    Pain and activity limitations in women and men with contemporary treated early RA compared to 10 years ago: the Swedish TIRA project2015In: Scandinavian Journal of Rheumatology, ISSN 0300-9742, E-ISSN 1502-7732, Vol. 44, no 4, 259-264 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: To study differences regarding pain and activity limitations during the 3 years following diagnosis in women and men with contemporary treated early RA compared with their counterparts who were diagnosed 10 years earlier. Method: This study was based on patients recruited to the Early Intervention in RA (TIRA) project. In the first cohort (TIRA-1) 320 patients were included in time for diagnosis during 1996-1998 and 463 patients were included in the second cohort (TIRA-2) during 2006-2009. Disease activity, pain intensity (Visual Analogue Scale, VAS), bodily pain (BP) in the 36-item Short Form Health Survey (SF-36), activity limitations (Health Assessment Questionnaire, HAQ), and medication were reported at inclusion and at follow-up after 1, 2, and 3 years. Results: Disease activity, pain, and activity limitations were pronounced at inclusion across both genders and in both cohorts, with some improvement observed during the first year after diagnosis. Disease activity did not differ between cohorts at inclusion but was significantly lower at the follow-ups in the TIRA-2 cohort, in which the patients were prescribed traditional disease-modifying anti-rheumatic drugs (DMARDs) and biological agents more frequently. In TIRA-2, patients reported significantly lower pain and activity limitations at all follow-ups, with men reporting lower pain than women. Women reported significantly higher activity limitations at all time points in TIRA-2. Conclusions: Pain and activity limitations were still pronounced in the contemporary treated early RA cohort compared with their counterparts diagnosed 10 years earlier and both of these factors need to be addressed in clinical settings.

    A System Identification Approach to Determining Listening Attention from EEG Signals2016In: 2016 24TH EUROPEAN SIGNAL PROCESSING CONFERENCE (EUSIPCO), IEEE , 2016, 31-35 p.Conference paper (Refereed)
    Abstract [en]

    We still have very little knowledge about how ourbrains decouple different sound sources, which is known assolving the cocktail party problem. Several approaches; includingERP, time-frequency analysis and, more recently, regression andstimulus reconstruction approaches; have been suggested forsolving this problem. In this work, we study the problem ofcorrelating of EEG signals to different sets of sound sources withthe goal of identifying the single source to which the listener isattending. Here, we propose a method for finding the number ofparameters needed in a regression model to avoid overlearning,which is necessary for determining the attended sound sourcewith high confidence in order to solve the cocktail party problem.

    Stable associations between behavioral problems and language impairments across childhood - the importance of pragmatic language problems2014In: Research in Developmental Disabilities, ISSN 0891-4222, E-ISSN 1873-3379, Vol. 35, no 5, 943-951 p.Article in journal (Refereed)
    Abstract [en]

    This study investigated language function associated with behavior problems, focusing on pragmatics. Scores on the Children’s Communication Checklist Second Edition (CCC-2) in a group of 40 adolescents (12–15 years) identified with externalizing behavior problems (BP) in childhood was compared to the CCC-2 scores in a typically developing comparison group (n=37). Behavioral, emotional and language problems were assessed by the Strengths and Difficulties Questionnaire (SDQ) and 4 language items, when the children in the BP group were 7–9 years (T1). They were then assessed with the SDQ and the CCC-2 when they were 12–15 years (T2). The BP group obtained poorer scores on 9/10 subscales on the CCC-2, and 70% showed language impairments in the clinical range. Language, emotional and peer problems at T1 were strongly correlated with pragmatic language impairments in adolescence. The findings indicate that assessment of language, especially pragmatics, is vital for follow-up and treatment of behavioral problems in children and adolescents.

    Guided Internet-based vs. face-to-face cognitive behavior therapy for psychiatric and somatic disorders: a systematic review and meta-analysis2014In: World Psychiatry, ISSN 1723-8617, E-ISSN 2051-5545, Vol. 13, no 3, 288-295 p.Article in journal (Refereed)
    Abstract [en]

    Internet-delivered cognitive behavior therapy (ICBT) has been tested in many research trials, but to a lesser extent directly compared to face-to-face delivered cognitive behavior therapy (CBT). We conducted a systematic review and meta-analysis of trials in which guided ICBT was directly compared to face-to-face CBT. Studies on psychiatric and somatic conditions were included. Systematic searches resulted in 13 studies (total N=1053) that met all criteria and were included in the review. There were three studies on social anxiety disorder, three on panic disorder, two on depressive symptoms, two on body dissatisfaction, one on tinnitus, one on male sexual dysfunction, and one on spider phobia. Face-to-face CBT was either in the individual format (n=6) or in the group format (n=7). We also assessed quality and risk of bias. Results showed a pooled effect size (Hedges' g) at post-treatment of -0.01 (95% CI: -0.13 to 0.12), indicating that guided ICBT and face-to-face treatment produce equivalent overall effects. Study quality did not affect outcomes. While the overall results indicate equivalence, there are still few studies for each psychiatric and somatic condition and many conditions for which guided ICBT has not been compared to face-to-face treatment. Thus, more research is needed to establish equivalence of the two treatment formats.

    A 3.5-year follow-up of Internet-delivered cognitive behavior therapy for major depression2013In: Journal of Mental Health, ISSN 0963-8237, E-ISSN 1360-0567, Vol. 22, no 2, 155-164 p.Article in journal (Refereed)
    Abstract [en]

    BackgroundInternet-delivered cognitive behavior therapy (ICBT) for major depression has been tested in several trials, but only with follow-ups up to 1.5 years.

    AimThe aim of this study was to evaluate the outcome of ICBT 3.5 years after treatment completion.Methods

    A total of 88 people with major depression were randomized to either guided self-help or e-mail therapy in the original trial. One-third was initially on a waiting-list. Treatment was provided for eight weeks and in this report long-term follow-up data were collected. Also included were data from post-treatment and six-month follow-up. A total of 58% (51/88) completed the 3.5-year follow-up. Analyses were performed using a random effects repeated measures piecewise growth model to estimate trajectory shape over time and account for missing data.

    ResultsResults showed continued lowered scores on the Beck Depression Inventory (BDI). No differences were found between the treatment conditions. A large proportion of participants (55%) had sought and received additional treatments in the follow-up period. A majority (56.9%) of participants had a BDI score lower than 10 at the 3.5-year follow-up.

    ConclusionsPeople with mild to moderate major depression may benefit from ICBT 3.5-years after treatment completion.

    Effects of Two Forms of Internet-Delivered Cognitive Behaviour Therapy for Depression on Future Thinking2013In: Cognitive Therapy and Research, ISSN 0147-5916, E-ISSN 1573-2819, Vol. 37, no 1, 29-34 p.Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to investigate if future thinking would change following two forms of Internet-delivered cognitive behavior therapy (ICBT) for major depression. A second aim was to study the association between pre-post changes in future thinking and prepost changes in depressive symptoms.

    Background: Effects of psychological treatments are most often tested with self-report inventories and seldom with tests of cognitive function.

    Method: We included data from 47 persons diagnosed with major depression who received either e-mail therapy or guided self-help during 8 weeks. Participants completed the future thinking task (FTT), in which they were asked to generate positive and negative events that they thought were going to happen in the future and rated the events in terms of emotion and likelihood. The FTT was completed before and after treatment. Data on depressive symptoms were also collected.

    Results: FTT index scores for negative events were reduced after  treatment. There was no increase for the positive events. Change scores for the FTT negative events and depression symptoms were significantly correlated.

    Conclusions: We conclude that ICBT may lead to decreased negative future thinking and that changes in depression symptoms correlate to some extent with reductions in negative future thinking.

    Cognitive correlates of visual speech understanding in hearing impaired individuals2001In: Journal of Deaf Studies and Deaf Education, ISSN 1081-4159, Vol. 6, no 2, 103-116 p.Article in journal (Refereed)
    Abstract [en]

    This study examined the extent to which different measures ofspeechreading performance correlated with particular cognitiveabilities in a population of hearing-impaired people. Althoughthe three speechreading tasks (isolated word identification,sentence comprehension, and text tracking) were highly intercorrelated,they tapped different cognitive skills. In this population,younger participants were better speechreaders, and, when agewas taken into account, speech tracking correlated primarilywith (written) lexical decision speed. In contrast, speechreadingfor sentence comprehension correlated most strongly with performanceon a phonological processing task (written pseudohomophone detection)but also on a span measure that may have utilized visual, nonverbalmemory for letters. We discuss the implications of this pattern.

    Dealing with Digits: Arithmetic, Memory and Phonology in Deaf Signers2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Deafness has been associated with poor abilities to deal with digits in the context of arithmetic and memory, and language modality-specific differences in the phonological similarity of digits have been shown to influence short-term memory (STM). Therefore, the overall aim of the present thesis was to find out whether language modality-specific differences in phonological processing between sign and speech can explain why deaf signers perform at lower levels than hearing peers when dealing with digits. To explore this aim, the role of phonological processing in digit-based arithmetic and memory tasks was investigated, using both behavioural and neuroimaging methods, in adult deaf signers and hearing non-signers, carefully matched on age, sex, education and non-verbal intelligence. To make task demands as equal as possible for both groups, and to control for material effects, arithmetic, phonological processing, STM and working memory (WM) were all assessed using the same presentation and response mode for both groups. The results suggested that in digit-based STM, phonological similarity of manual numerals causes deaf signers to perform more poorly than hearing non-signers. However, for  digit-based WM there was no difference between the groups, possibly due to differences in allocation of resources during WM. This indicates that similar WM for the two groups can be generalized from lexical items to digits. Further, we found that in the present work deaf signers performed better than expected and on a par with hearing peers on all arithmetic tasks, except for multiplication, possibly because the groups studied here were very carefully matched. However, the neural networks recruited for arithmetic and phonology differed between groups. During multiplication tasks, deaf signers showed an increased  reliance on cortex of the right parietal lobe complemented by the left inferior frontal gyrus. In contrast, hearing non-signers relied on cortex of the left frontal and parietal lobes during multiplication. This suggests that while hearing non-signers recruit phonology-dependent arithmetic fact retrieval processes for multiplication, deaf signers recruit non-verbal magnitude manipulation processes. For phonology, the hearing non-signers engaged left lateralized frontal and parietal areas within the classical perisylvian language network. In deaf signers, however, phonological processing was limited to cortex of the left occipital lobe, suggesting that sign-based phonological processing does not necessarily activate the classical language network. In conclusion, the findings of the present thesis suggest that language modality-specific differences between sign and speech in different ways can explain why deaf signers perform at lower levels than hearing non-signers on tasks that include dealing with digits.

    Abstract [en]

    Similar working memory (WM) for lexical items has been demonstrated for signers and non-signers while short-term memory (STM) is regularly poorer in deaf than hearing individuals. In the present study, we investigated digit-based WM and STM in Swedish and British deaf signers and hearing non-signers. To maintain good experimental control we used printed stimuli throughout and held response mode constant across groups. We showed that deaf signers have similar digit-based WM performance, despite shorter digit spans, compared to well-matched hearing non-signers. We found no difference between signers and non-signers on STM span for letters chosen to minimize phonological similarity or in the effects of recall direction. This set of findings indicates that similar WM for signers and non-signers can be generalized from lexical items to digits and suggests that poorer STM in deaf signers compared to hearing non-signers may be due to differences in phonological similarity across the language modalities of sign and speech.

    Abstract [en]

    Deaf students generally lag several years behind hearing peers in arithmetic, but little is known about the mechanisms behind this. In the present study we investigated how phonological skills interact with arithmetic. Eighteen deaf signers and eighteen hearing non-signers took part in an experiment that manipulated arithmetic and phonological knowledge in the language modalities of sign and speech. Independent tests of alphabetical and native language phonological skills were also administered. There was no difference in performance between groups on subtraction, but hearing non-signers performed better than deaf signers on multiplication. For the deaf signers but not the hearing non-signers, multiplicative reasoning was associated with both alphabetical and phonological skills. This indicates that deaf signing adults rely on language processes to solve multiplication tasks, possibly because automatization of multiplication is less well established in deaf adults.

    Abstract [en]

    Arithmetic and language processing involve similar neural networks, but the relative engagement remains unclear. In the present study we used fMRI to compare activation for phonological, multiplication and subtraction tasks, keeping the stimulus material constant, within a predefined language-calculation network including left inferior frontal gyrus and angular gyrus (AG) as well as superior parietal lobule and the intraparietal sulcus bilaterally. Results revealed a generally left lateralized activation pattern within the language-calculation network for phonology and a bilateral activation pattern for arithmetic, and suggested regional differences between tasks. In particular, we found a more prominent role for phonology than arithmetic in pars opercularis of the left inferior frontal gyrus but domain generality in pars triangularis. Parietal activation patterns demonstrated greater engagement of the visual and quantity systems for calculation than language. This set of findings supports the notion of a common, but regionally differentiated, language-calculation network. (C) 2015 The Authors. Published by Elsevier Inc.

    Abstract [en]

    Evidence suggests that the lag reported in mathematics for deaf signers derives from difficulties related to the verbal system of number processing as described in the triple code model. For hearing individuals the verbal system has been shown to be recruited for both arithmetic and language tasks. In the present study we investigate for the first time neuronal representations of arithmetic in deaf signers. We examine if the neural network supporting arithmetic and language, including the horizontal portion of the intraparietal sulcus (HIPS), the superior parietal lobule (SPL) bilaterally, the left angular gyrus (AG), pars opercularis (POPE) and pars triangularis (PTRI) of the left inferior frontal gyrus (IFG), is differently recruited for deaf and hearing individuals. Imaging data were collected from 16 deaf signers and 16 well-matched hearing nonsigners, using the same stimulus material for all tasks, but with different cues. During multiplication, deaf signers recruited rHIPS more than hearing non-signers, suggesting greater involvement of magnitude manipulation processes related to the quantity system, whereas there was no evidence that the verbal system was recruited. Further, there was no support for the notion of a common representation of phonology for sign and speech as previously suggested.

    Deaf signers and hearing non-signers recruit similar networks for arithmetic and phonological tasks2013Conference paper (Other academic)
    Abstract [en]

    Profoundly deaf individuals sometimes have difficulty with arithmetic and phonological tasks. In the present study we investigate if these differences can be attributed to differences in recruitment of neurobiological networks. Seventeen hearing non-signers (HN) and sixteen deaf signers (DS) matched on age, gender and non-verbal intelligence took part in an fMRI study. In the scanner three digit/letter pairs were visually presented and the participants performed six different blocked tasks tapping processing of digit and letter order, multiplication, subtraction and phonological ability. Data were analysed using two 2x2x2 ANOVAs; process (arithmetic, language) x level (high, low) x group (DS, HN). A main effect of process revealed language networks in the left inferior frontal gryus, supramarginal gyrus, fusiform gyrus and insula. Arithmetic networks included left middle orbital gyrus and superior medial gyrus. A main effect of level revealed low level processing (digit/letter order) in the right middle occipital gyrus and the right precuneus and high level processing (subtraction/multiplication/phonological ability) in left inferior frontal gyrus. There was no main effect of group but a significant task x group interaction in the right temporal pole which in DS (but not HN) was activated more for arithmetic than language processing (pfwe = .022) when multiplication was included in the analysis. This region is implicated in conceptual representation. These results suggest that both arithmetic and language are processed similarly by DS and HN with possible between-group differences in the use of conceptual representation in arithmetic and language tasks.

    Deaf signers use magnitude manipulatioin strategies for mulitplication: fMRI evidence2014Manuscript (preprint) (Other academic)
    Abstract [en]

    Evidence suggests that the lag reported in mathematics for deaf signers derives from difficulties related to the verbal system of number processing as described in the triple code model. For hearing individuals the verbal system has been shown to be recruited for both arithmetic and language tasks. In the present study we investigate for the first time neuronal representations of arithmetic in deaf signers. We examine if the neural network supporting arithmetic and language, including the horizontal portion of the intraparietal sulcus (HIPS), the superior parietal lobule (SPL) bilaterally, the left angular gyrus (AG), pars opercularis (POPE) and pars triangularis (PTRI) of the left inferior frontal gyrus (IFG), is differently recruited for deaf and hearing individuals. Imaging data were collected from 16 deaf signers and 16 well-matched hearing nonsigners, using the same stimulus material for all tasks, but with different cues. During multiplication, deaf signers recruited rHIPS more than hearing non-signers, suggesting greater involvement of magnitude manipulation processes related to the quantity system, whereas there was no evidence that the verbal system was recruited. Further, there was no support for the notion of a common representation of phonology for sign and speech as previously suggested.

    Phonology and arithmetic in the language-calculation network2015In: Brain and Language, ISSN 0093-934X, E-ISSN 1090-2155, Vol. 143, 97-105 p.Article in journal (Refereed)
    Abstract [en]

    Arithmetic and language processing involve similar neural networks, but the relative engagement remains unclear. In the present study we used fMRI to compare activation for phonological, multiplication and subtraction tasks, keeping the stimulus material constant, within a predefined language-calculation network including left inferior frontal gyrus and angular gyrus (AG) as well as superior parietal lobule and the intraparietal sulcus bilaterally. Results revealed a generally left lateralized activation pattern within the language-calculation network for phonology and a bilateral activation pattern for arithmetic, and suggested regional differences between tasks. In particular, we found a more prominent role for phonology than arithmetic in pars opercularis of the left inferior frontal gyrus but domain generality in pars triangularis. Parietal activation patterns demonstrated greater engagement of the visual and quantity systems for calculation than language. This set of findings supports the notion of a common, but regionally differentiated, language-calculation network. (C) 2015 The Authors. Published by Elsevier Inc.

    Deaf signers use phonology to do arithmetic2014In: Learning and individual differences, ISSN 1041-6080, E-ISSN 1873-3425, Vol. 32, 246-253 p.Article in journal (Refereed)
    Abstract [en]

    Deaf students generally lag several years behind hearing peers in arithmetic, but little is known about the mechanisms behind this. In the present study we investigated how phonological skills interact with arithmetic. Eighteen deaf signers and eighteen hearing non-signers took part in an experiment that manipulated arithmetic and phonological knowledge in the language modalities of sign and speech. Independent tests of alphabetical and native language phonological skills were also administered. There was no difference in performance between groups on subtraction, but hearing non-signers performed better than deaf signers on multiplication. For the deaf signers but not the hearing non-signers, multiplicative reasoning was associated with both alphabetical and phonological skills. This indicates that deaf signing adults rely on language processes to solve multiplication tasks, possibly because automatization of multiplication is less well established in deaf adults.

    Relationship between distortion, hearing loss and working memory for digital noise reduction2015In: Ear and Hearing, ISSN 0196-0202, E-ISSN 1538-4667, Vol. 36, no 5, 505-516 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: This study considered speech modified by additive babble combined with noise-suppression processing. The purpose was to determine the relative importance of the signal modifications, individual peripheral hearing loss, and individual cognitive capacity on speech intelligibility and speech quality.

    Design: The participant group consisted of 31 individuals with moderate high-frequency hearing loss ranging in age from 51 to 89 years (mean = 69.6 years). Speech intelligibility and speech quality were measured using low-context sentences presented in babble at several signal-to-noise ratios. Speech stimuli were processed with a binary mask noise-suppression strategy with systematic manipulations of two parameters (error rate and attenuation values). The cumulative effects of signal modification produced by babble and signal processing were quantified using an envelope-distortion metric. Working memory capacity was assessed with a reading span test. Analysis of variance was used to determine the effects of signal processing parameters on perceptual scores. Hierarchical linear modeling was used to determine the role of degree of hearing loss and working memory capacity in individual listener response to the processed noisy speech. The model also considered improvements in envelope fidelity caused by the binary mask and the degradations to envelope caused by error and noise.

    Results: The participants showed significant benefits in terms of intelligibility scores and quality ratings for noisy speech processed by the ideal binary mask noise-suppression strategy. This benefit was observed across a range of signal-to-noise ratios and persisted when up to a 30% error rate was introduced into the processing. Average intelligibility scores and average quality ratings were well predicted by an objective metric of envelope fidelity. Degree of hearing loss and working memory capacity were significant factors in explaining individual listener’s intelligibility scores for binary mask processing applied to speech in babble. Degree of hearing loss and working memory capacity did not predict listeners’ quality ratings.

    Conclusions: The results indicate that envelope fidelity is a primary factor in determining the combined effects of noise and binary mask processing for intelligibility and quality of speech presented in babble noise. Degree of hearing loss and working memory capacity are significant factors in explaining variability in listeners’ speech intelligibility scores but not in quality ratings.

    Relationship between distortion and working memory for digital noise-reduction processing in hearing aids2014In: Journal of the Acoustical Society of America, ISSN 0001-4966, Vol. 133, no 5Article in journal (Refereed)
    Abstract [en]

    Several recent studies have shown a relationship between working memory and the ability of older adults to benefit from specific advanced signal processing algorithms in hearing aids. In this study, we quantify tradeoffs between benefit due to noise reduction and the perceptual costs associated with distortion caused by the noise reduction algorithm. We also investigate the relationship between these tradeoffs and working memory abilities. Speech intelligibility, speech quality, and perceived listening effort were measured in a cohort of elderly adults with hearing loss. Test materials were low-context sentences presented in fluctuating noise conditions at several signal-to-noise ratios. Speech stimuli were processed with a binary mask noise-reduction strategy. The amount of distortion produced by the noise reduction algorithm was parametrically varied by manipulating two binary mask parameters, error rate, and attenuation rate. Working memory was assessed with a reading span test. Results will be discussed in terms of the extent to which intelligibility, quality, and effort ratings are explained by the amount of distortion and/or noise and by working memory ability.

    The Relationship between Reading Comphehension, Working Memory and Language in Children with Cochlear Implants2007In: Acta Neuropsychologica, ISSN 1730-7503, Vol. 5, no 4, 163-186 p.Article in journal (Refereed)
    Abstract [en]

    and profound hearing impairment treated by cochlear implants (CI). In this study we explore this relationship in sixteen Swedish children with CI. We found that over 60% of the children with CI performed at the level of their hearing peers in a reading comprehension test. Demographic factors were not predictive of reading comprehension, but a complex working memory task was. Reading percentile was significantly correlated to the working memory test, but no other correlations between reading and cognitive/linguistic factors remained significant after age was factored out. Individual results from a comparison of the two best and the two poorest readers corroborate group results, confirming the important role of working memory for reading as measured by comprehension of words and sentences in this group of children.

    ICBEN review of research on the biological effects of noise 2011-20142015In: Noise & Health, ISSN 1463-1741, E-ISSN 1998-4030, Vol. 17, no 75, 57-82 p.Article, review/survey (Refereed)
    Abstract [en]

    The mandate of the International Commission on Biological Effects of Noise (ICBEN) is to promote a high level of scientific research concerning all aspects of noise-induced effects on human beings and animals. In this review, ICBEN team chairs and co-chairs summarize relevant findings, publications, developments, and policies related to the biological effects of noise, with a focus on the period 2011-2014 and for the following topics: Noise-induced hearing loss; nonauditory effects of noise; effects of noise on performance and behavior; effects of noise on sleep; community response to noise; and interactions with other agents and contextual factors. Occupational settings and transport have been identified as the most prominent sources of noise that affect health. These reviews demonstrate that noise is a prevalent and often underestimated threat for both auditory and nonauditory health and that strategies for the prevention of noise and its associated negative health consequences are needed to promote public health.

    Speech-language pathologists preferences for patient-centeredness2017In: Journal of Communication Disorders, ISSN 0021-9924, E-ISSN 1873-7994, Vol. 68, 81-88 p.Article in journal (Refereed)
    Abstract [en]

    Purpose: Preferences for patient-centeredness is an important indicator in healthcare service delivery. However, it remains largely unexplored in the field of communication science and disorders. This study investigated speech-language pathologists (SLPs) preferences for patient-centeredness Method: The study involved a cross-sectional survey design. SLPs (n = 102) fully completed the modified Patient-Practitioner Orientation Scale (PPOS; Krupat et al, 2000) and also provided demographic details. Data were analyzed using descriptive statistics, correlation, and linear regression methods. Results: Mean PPOS scores indicated that SLPs value patient-centeredness. There was a strong positive correlation among sharing and caring subscales with the full-scale. Results from the linear regression modeling suggested no relationship between demographic factors and preferences for patient-centeredness. Conclusions: SLPs value patient-centeredness, although there may be regional and cultural variations. Qualitative investigations may help uncover dimensions of patient-centeredness that were not captured in the PPOS scale. In addition, further research should explore congruence in preferences for patient-centeredness among SLPs and patients.

    Spectrotemporal modulation sensitivity as a predictor of speech intelligibility in noise with hearing aids2014In: Spectrotemporal modulation sensitivity as a predictor of speech intelligibility in noise with hearing aids, 2014Conference paper (Refereed)
    Abstract [en]

    The audiogram predicts less than a third of the variance in speech reception thresholds (SRTs) for hearing-impaired (HI) listeners properly fit with individualized frequency-dependent gain. The remaining variance is often attributed to a combination of su-prathreshold distortion in the auditory pathway and non-auditory factors such as cogni-tive processing. Distinguishing between these factors requires a measure of suprathresh-old auditory processing to account for the non-cognitive contributions. Preliminary re-sults in 12 HI listeners identified a correlation between spectrotemporal modulation (STM) sensitivity and speech intelligibility in noise presented over headphones. The cur-IHCON 2014 27 August 13-17, 2014rent study assessed the effectiveness of STM sensitivity as a measure of suprathreshold auditory function to predict free-field SRTs in noise for a larger group of 47 HI listeners with hearing aids.SRTs were measured for Hagerman sentences presented at 65 dB SPL in stationary speech-weighted noise or four-talker babble. Pre-recorded speech and masker stimuli were played through a small anechoic chamber equipped with a master hearing aid pro-grammed with individualized gain. The output from an IEC711 Ear Simulator was played binaurally through insert earphones. Three processing algorithms were examined: linear gain, linear gain plus noise reduction, or fast-acting compressive gain.STM stimuli consist of spectrally-rippled noise with spectral-peak frequencies that shift over time. STM with a 2-cycle/octave spectral-ripple density and a 4-Hz modulation rate was applied to a 2-kHz lowpass-filtered pink-noise carrier. Stimuli were presented over headphones at 80 dB SPL (±5-dB roving). The threshold modulation depth was estimated adaptively in a two-alternative forced-choice task.STM sensitivity was strongly correlated (R2=0.48) with the global SRT (i.e., the SRTs averaged across masker and processing conditions). The high-frequency pure-tone aver-age (3-8 kHz) and age together accounted for 23% of the variance in global SRT. STM sensitivity accounted for an additional 28% of the variance in global SRT (total R2=0.51) when combined with these two other metrics in a multiple-regression analysis. Correla-tions between STM sensitivity and SRTs for individual conditions were weaker for noise reduction than for the other algorithms, and marginally stronger for babble than for sta-tionary noise.The results are discussed in the context of previous work suggesting that STM sensitivity for low rates and low carrier frequencies is impaired by a reduced ability to use temporal fine-structure information to detect slowly shifting spectral peaks. STM detection is a fast, simple test of suprathreshold auditory function that accounts for a substantial pro-portion of variability in hearing-aid outcomes for speech perception in noise.

    Spectrotemporal Modulation Sensitivity as a Predictor of Speech-Reception Performance in Noise With Hearing Aids2016In: TRENDS IN HEARING, ISSN 2331-2165, Vol. 20, 2331216516670387Article in journal (Refereed)
    Abstract [en]

    The audiogram predicts amp;lt;30% of the variance in speech-reception thresholds (SRTs) for hearing-impaired (HI) listeners fitted with individualized frequency-dependent gain. The remaining variance could reflect suprathreshold distortion in the auditory pathways or nonauditory factors such as cognitive processing. The relationship between a measure of suprathreshold auditory function-spectrotemporal modulation (STM) sensitivity-and SRTs in noise was examined for 154 HI listeners fitted with individualized frequency-specific gain. SRTs were measured for 65-dB SPL sentences presented in speech-weighted noise or four-talker babble to an individually programmed master hearing aid, with the output of an ear-simulating coupler played through insert earphones. Modulation-depth detection thresholds were measured over headphones for STM (2cycles/octave density, 4-Hz rate) applied to an 85-dB SPL, 2-kHz lowpass-filtered pink-noise carrier. SRTs were correlated with both the high-frequency (2-6 kHz) pure-tone average (HFA; R-2 = .31) and STM sensitivity (R-2 = .28). Combined with the HFA, STM sensitivity significantly improved the SRT prediction (Delta R-2 = .13; total R-2 = .44). The remaining unaccounted variance might be attributable to variability in cognitive function and other dimensions of suprathreshold distortion. STM sensitivity was most critical in predicting SRTs for listenersamp;lt;65 years old or with HFA amp;lt;53 dB HL. Results are discussed in the context of previous work suggesting that STM sensitivity for low rates and low-frequency carriers is impaired by a reduced ability to use temporal fine-structure information to detect dynamic spectra. STM detection is a fast test of suprathreshold auditory function for frequencies amp;lt;2 kHz that complements the HFA to predict variability in hearing-aid outcomes for speech perception in noise.

    Speech-in-Speech Listening on the LiSN-S Test by Older Adults With Good Audiograms Depends on Cognition and Hearing Acuity at High Frequencies2015In: Ear and Hearing, ISSN 0196-0202, E-ISSN 1538-4667, Vol. 36, no 1, 24-41 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: The main objective was to investigate age-related differences on the listening in spatialized noise-sentences (LiSN-S) test in adults with normal audiometric thresholds in most of the speech range. A second objective was to examine the contributions of auditory, cognitive, and linguistic abilities to LiSN-S outcomes. Design: The LiSN-S test was administered to participants in an older group (M-Age = 72.0, SD = 4.3 years) and a younger group (M-Age = 21.7, SD = 2.6 years) with N = 26 per group. All the participants had clinically normal audiometric thresholds at frequencies up to and including 3000 Hz. The LiSN-S test yields a speech reception threshold (SRT) in each of the four speech-in-speech listening conditions that differ in the availability of voice difference cues and/or spatial separation cues. Based on these four SRTs, the scores were calculated for the talker advantage, the spatial advantage, and the total advantage as a result of both the types of cues. Additionally, the participants completed four auditory temporal-processing tests, a cognitive screening test, a vocabulary test, and tests of linguistic closure for high-and low-context sentences. The contributions of these predictor variables and measures of pure-tone hearing acuity to LiSN-S outcomes were analyzed for both the groups using regression analyses. Results: Younger listeners outperformed the older listeners on all four LiSN-S SRTs and all the three LiSN-S advantage measures. Age-related differences were larger for conditions involving the use of spatial cues. For the younger group, all LiSN-S SRTs were predicted by the measure of linguistic closure in low-context sentences; in addition, the SRT for the condition with voice difference cues but without spatial separation cues was predicted by vocabulary, and the SRT for the condition with both voice difference cues and spatial separation cues was predicted by temporal resolution at low frequencies. Vocabulary also contributed to the talker advantage in the younger group, whereas the spatial advantage was predicted by high-frequency pure-tone hearing acuity in the range 6,000 to 10,000 Hz (pure-tone average [ PTA] HIGH). For the older group, the LiSN-S SRT in the condition with neither voice difference cues nor spatial separation cues was predicted by age; their other three LiSN-S SRTs and all advantage measures were predicted by PTA HIGH. In addition, for the older group, cognition predicted LiSN-S SRT outcomes in three of the four conditions. Measures of auditory temporal processing, linguistic abilities, or hearing acuity up to and including 4000 Hz did not predict LiSN-S outcomes in this group. Conclusions: LiSN-S outcomes were poorer for adults aged 65 years or older, even those with good audiograms, compared with younger adults and also compared with people up to the age of 60 years from a previous study. In the present study, regardless of the types of cues, auditory and cognitive interactions were reflected by the combined influences on LiSN-S outcomes of high-frequency hearing acuity and measures of linguistic and cognitive processing. The data also suggest a hierarchy in the deployment of processing resources, which would account for the observed shift from linguistic abilities in the younger group to general cognitive abilities in the older group.

    How Linguistic Closure and Verbal Working Memory Relate to Speech Recognition in Noise-A Review2013In: Trends in Amplification, ISSN 1084-7138, Vol. 17, no 2, 75-93 p.Article in journal (Refereed)
    Abstract [en]

    The ability to recognize masked speech, commonly measured with a speech reception threshold (SRT) test, is associated with cognitive processing abilities. Two cognitive factors frequently assessed in speech recognition research are the capacity of working memory (WM), measured by means of a reading span (Rspan) or listening span (Lspan) test, and the ability to read masked text (linguistic closure), measured by the text reception threshold (TRT). The current article provides a review of recent hearing research that examined the relationship of TRT and WM span to SRTs in various maskers. Furthermore, modality differences in WM capacity assessed with the Rspan compared to the Lspan test were examined and related to speech recognition abilities in an experimental study with young adults with normal hearing (NH). Span scores were strongly associated with each other, but were higher in the auditory modality. The results of the reviewed studies suggest that TRT and WM span are related to each other, but differ in their relationships with SRT performance. In NH adults of middle age or older, both TRT and Rspan were associated with SRTs in speech maskers, whereas TRT better predicted speech recognition in fluctuating nonspeech maskers. The associations with SRTs in steady-state noise were inconclusive for both measures. WM span was positively related to benefit from contextual information in speech recognition, but better TRTs related to less interference from unrelated cues. Data for individuals with impaired hearing are limited, but larger WM span seems to give a general advantage in various listening situations.

    New measures of masked text recognition in relation to speech-in-noise perception and their associations with age and cognitive abilities2012In: Journal of Speech, Language and Hearing Research, ISSN 1092-4388, E-ISSN 1558-9102, Vol. 55, no 1, 194-209 p.Article in journal (Refereed)
    Abstract [en]

    Purpose: This research aimed to increase the analogy between text reception threshold (TRT) and speech reception threshold (SRT) and to examine the TRT's value in estimating cognitive abilities important for speech comprehension in noise.

    Method: We administered five TRT versions, SRT tests in stationary (SRTSTAT) and modulated (SRTMOD) noise, and two cognitive tests: a reading span (RSpan) test for working memory capacity, and a letter-digit-substitution test for information processing speed. Fifty-five normal hearing adults (18–78 years, mean = 44) participated. We examined mutual associations of the tests and their predictive value for the SRTs with correlation and linear regression analyses.

    Results: SRTs and TRTs were well associated, also when controlling for age. Correlations for the SRTSTAT were generally lower than for the SRTMOD. The cognitive tests were only correlated to the SRTs when age was not controlled for. Age and the TRTs were the only significant predictors of SRTMOD. SRTSTATwas predicted by level of education and some of the TRT versions.

    Conclusions: TRTs and SRTs are robustly associated, nearly independent of age. The association between SRTs and RSpan is largely age-dependent. The TRT test and the RSpan test measure different non-auditory components of linguistic processing relevant for speech perception in noise.

    Internet-Based Intervention for Tinnitus: Outcome of a Single-Group Open Trial2017In: Journal of american academy of audiology, ISSN 1050-0545, E-ISSN 2157-3107, Vol. 28, no 4, 340-351 p.Article in journal (Refereed)
    Abstract [en]

    Background: Managing chronic tinnitus is challenging, and innovative ways to address the resulting health-care burden are required. Internet-based cognitive behavioral therapy (iCBT) for tinnitus shows promise as a cost-effective treatment option. The feasibility and effectiveness of iCBT in the United Kingdom are yet to be explored. Furthermore, it is not known if iCBT can be supported by an audiologist rather than a psychologist. Purpose: This study aimed to determine the feasibility of guided iCBT using audiological support on tinnitus distress and tinnitus-related comorbidities. Furthermore, it aimed to establish the feasibility of iCBT for tinnitus distress in the United Kingdom, by determining recruitment, attrition, and compliance rates. Finally, it aimed to identify which aspects of the protocol require refinement for subsequent clinical trials. Research Design: A single-group open trial design was implemented. This study would serve as a prerequisite study, to identify barriers, before undertaking effectiveness trials. Study Sample: Participants consisted of 37 adults (18 males, 19 females), with an age range of between 50 and 59 yr. The mean preintervention tinnitus severity rating was 56.15 (standard deviation = 18.35), which is categorized as "severe tinnitus" as measured by the Tinnitus Functional Index (TFI). Five participants withdrew during the study, and 29 of the remaining participants completed the postintervention questionnaire. Intervention: The guided iCBT intervention ran over an eight-week period and consisted of 16 obligatory modules and five optional modules. The intervention was designed to be interactive, interesting, and stimulating. A key element was the provision of support from an audiologist throughout the program. Data Collection and Analysis: Online questionnaires were used throughout the study. These were administered at baseline and postintervention to determine attrition and compliance rates and to facilitate sample size estimates for further clinical trials. Outcome measures for tinnitus severity, hearing handicap, insomnia, cognitive functioning, hyperacusis, anxiety, depression, and life satisfaction were used to investigate the effects of iCBT with audiological support. In addition, a weekly questionnaire was incorporated to monitor change in tinnitus distress while undertaking the intervention. Results: Feasibility was established using an audiologist to support this guided iCBT intervention, as a significant change postintervention was found for tinnitus severity, as measured by the TFI and the Tinnitus Handicap Inventory, Screening version. The attrition rate was 22% and compliance was variable. Although these results were based on a small sample, they provide encouraging evidence for the feasibility of delivering iCBT treatment for tinnitus symptoms with audiology support in the United Kingdom. Conclusions: An Internet-based intervention of tinnitus appears to be feasible in the United Kingdom when using audiological support. Randomized controlled trials to further investigate the effectiveness of iCBT for tinnitus in the United Kingdom are required.

    Guided Internet-based versus face-to-face clinical care in the management of tinnitus: study protocol for a multi-centre randomised controlled trial2017In: Trials, ISSN 1745-6215, E-ISSN 1745-6215, Vol. 18, 186Article in journal (Refereed)
    Abstract [en]

    Background: Innovative strategies are required to improve access to evidence-based tinnitus interventions. A guided Internet-based cognitive behavioural therapy (iCBT) intervention for tinnitus was therefore developed for a U.K. population. Initial clinical trials indicated efficacy of iCBT at reducing tinnitus severity and associated comorbidities such as insomnia and depression. The aim of this phase III randomised controlled trial is to compare this new iCBT intervention with an established intervention, namely face-to-face clinical care for tinnitus. Methods/design: This will be a multi-centre study undertaken across three hospitals in the East of England. The design is a randomised, two-arm, parallel-group, non-inferiority trial with a 2-month follow-up. The experimental group will receive the guided iCBT intervention, whereas the active control group will receive the usual face-to-face clinical care. An independent researcher will randomly assign participants, using a computer-generated randomisation schedule, after stratification for tinnitus severity. There will be 46 participants in each group. The primary assessment measure will be the Tinnitus Functional Index. Data analysis will establish whether non-inferiority is achieved using a pre-defined non-inferiority margin. Discussion: This protocol outlines phase III of a clinical trial comparing a new iCBT with established face-to-face care for tinnitus. If guided iCBT for tinnitus proves to be as effective as the usual tinnitus care, it may be a viable additional management route for individuals with tinnitus. This could increase access to evidence-based effective tinnitus care and reduce the pressures on existing health care systems.

    Internet-based cognitive behavioural therapy for adults with tinnitus in the UK: study protocol for a randomised controlled trial2015In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 5, no 9, e008241- p.Article in journal (Refereed)
    Abstract [en]

    Introduction: Tinnitus is one of the most distressing hearing-related symptoms. Innovative ways of managing tinnitus distress and the related healthcare burden of treating tinnitus are required. An internet-based cognitive behavioural therapy (iCBT) intervention has been developed in Sweden to improve access to evidence-based tinnitus treatments. This study aims to determine the feasibility and effectiveness of iCBT in reducing the impact associated with tinnitus, in the UK. It, furthermore, aims to establish whether there are subgroups of tinnitus sufferers for whom this iCBT intervention may be more suitable. Methods and analysis: A two-armed randomised control trial-with a 1-year follow-up design-will be used to evaluate the effectiveness of iCBT on tinnitus distress. A delayed treatment design using a weekly check-in control group will be used. 70 participants will be randomly assigned to each group by an independent researcher by using a computer-generated randomisation schedule, and after being prestratified for age and tinnitus severity. They will undergo the iCBT e-health intervention online together with audiological therapeutic support. The main outcome measure is the Tinnitus Functional Index. Process evaluation of the intervention will also be conducted. Data analysis will be in accordance with Consolidated Standards of Reporting Trials guidelines. Ethics and dissemination: Ethical approval has been granted. If this intervention proves effective, it may be possible that at least some tinnitus sufferers can be managed though an iCBT e-learning treatment programme. This would be cost effective and potentially will free up services for those with more severe problems that need face-to-face treatment.
