Abstract [en]

Introduction

Today's assessment instruments for dissociation among adolescents are either relatively extensive or are specifically designed to identify either psychoform or somatoform dissociation.

Objective

A questionnaire that is shorter than any of the existing questionnaires and is concerned with both forms of dissociation would be helpful for both clinicians and researchers.

Method

Existing data from 462 adolescents who had answered Dis-Q Sweden and SDQ-20 were used to create a new questionnaire consisting of 12 items. A pilot study with 42 participants 15-19 years old, was carried out to test this new instrument, Dissociation Screening Questionnaire 12 (DSQ-12). DSQ-12 was then tested on 451 adolescents 10 to 20 years old. A matched clinical group of 25 adolescents in the same age range was used, in order to test the classification performance of DSQ-12.

Results

Results showed good reliability, convergent and construct validity was satisfactory, and dissociation differed between age groups as well as between genders.

Conclusions

Conclusions are that the developed DSQ-12 performed well psychometrically, was reliable and valid. DSQ-12 is easy to answer and is suitable for clinical screening purposes and future research.

Abstract [en]

In addition to money or other compensation, other motives for selling sex may be important in a welfare country such as Sweden. The aim of this study was to carry out an exploratory investigation of adolescents motives for selling sex in a population-based survey in Sweden. A total of 5839 adolescents from the third year of Swedish high school, mean age 18.0 years, participated in the study. The response rate was 59.7% and 51 students (0.9%) reported having sold sex. Exploratory factor analysis and hierarchical cluster analysis were used to identify groups of adolescents according to underlying motives for selling sex. Further analyses were carried out for characteristics of selling sex and risk factors. Three groups of adolescents were categorized according to their motives for selling sex: Adolescents reporting; 1) Emotional reasons, being at a greater risk of sexual abuse, using sex as a means of self-injury and having a non-heterosexual orientation. 2) Material but no Emotional reasons, who more often receive money as compensation and selling sex to a person over 25 years of age, and 3) Pleasure or no underlying motive for selling sex reported, who were mostly heterosexual males selling sex to a person under 25 years of age, the buyer was not known from the Internet, the reward was seldom money and this group was less exposed to penetrative sexual abuse or using sex as a means of self-injury. In conclusion, adolescents selling sex are a heterogeneous group in regard to underlying motives.

Abstract [en]

Introduction. – The Trauma Symptom Inventory-2 (TSI-2) is a broad-spectrum assessment instrumentdesigned to identify symptoms that can appear in the aftermath of potentially traumatic experiences.

Objective. – This study aimed to evaluate the external and internal validity of this newly reconstructedinstrument.Method. – In total, 696 individuals participated in the study, including 83 psychiatric outpatients. Participants answered the TSI-2, together with a trauma history questionnaire, and other questionnairesassumed to correlate with the different scales included in the TSI-2.

Results. – Validity was evaluated by correlations between the TSI-2 and the other instruments and bythe differences between clinical and non-clinical populations. Reliability was calculated by testinginternal consistency and test-re-test reliability. A confirmatory factor analysis (CFA) was computed totest the postulated four-factor structure. Cronbach’s alpha was found to be good and ranged froma = .77 to .91 and test-retest reliability was strong. Strong to satisfactory correlations were foundbetween the TSI-2 and the other instruments. The student sample scored significantly lower than theclinical group on all clinical scales. Sensitivity and specificity were calculated with different cut-offscores.

Conclusion. – Despite the CFA demonstrating a questionably good model of fit, most of the scales provedto be sound and the TSI-2 could be recommended as a broad-spectrum assessment instrument.

Abstract [en]

Speech perception in noise is dependent on stimulus-driven and knowledge-driven processes. Here we investigate the neural correlates and time course of discrepancies between incoming auditory information (i.e. stimulus-driven processing) and linguistic expectations (knowledge-driven processing) by including 20 normal hearing adults in a MEG study. Participants read 48 rhyming sentence pairs beforehand. In the scanner, they listened to sentences that corresponded exactly to the read sentences except that the last word (presented after 1600 millisecond delay and with 50% intelligibility) was only correct in half of the cases. Otherwise, it was 1) phonologically but not semantically related, 2) semantically but not phonologically related, or 3) neither phonologically nor semantically related to the sentence. Participants indicated by button press whether the last word matched the sentence they had read outside the scanner. Behavioural results showed more errors in condition 1 than in conditions 2 or 3, suggesting that phonological compatibility overrides semantic discrepancy when intelligibility is poor. Event-related field analysis demonstrated larger activity on frontal sites for correct than unrelated words, suggesting that the former were more accurately expected than the latter. An early M170 component was also observed, possibly reflecting expectation violation in the auditory modality. Dipole analysis will reveal whether M170 could be modulated by type of linguistic discrepancy. Distributed-network analysis will further our understanding of the time course and neural correlates of discrepancies between incoming auditory information and linguistic expectations.

Abstract [en]

Sport participation is associated with a risk of sports-related injuries and illnesses, and Paralympic athletes additional medical issues can be a challenge to health care providers and medical staff. However, few prospective studies have assessed sports-related injuries and illnesses in Paralympic sport (SRIIPS) over time. Advances in mobile phone technology and networking systems offer novel opportunities to develop innovative eHealth applications for collection of athletes self-reports. Using eHealth applications for collection of self-reported SRIIPS is an unexplored area, and before initiation of full-scale research of SRIIPS, the feasibility and usability of such an approach needs to be ascertained.

Abstract [en]

Purpose: This research analysed general pain intensity, hand pain at rest and hand pain during activity in women and men in early rheumatoid arhtritis (RA).

Method: Out of the 454 patients that were recruited into the Swedish early RA project "TIRA" the 373 patients (67% women) that remained at 12 months follow-up are reported here. Disease activity 28 joint score (DAS-28), disability (Health Assessment Questionnaire = HAQ) and pain (VAS) were recorded at inclusion and after 3 (M3), 6 (M6) and 12 (M12) months. General pain, hand pain during rest, hand pain during test of grip force as assessed by Grippit™, prescribed disease-modifying anti-inflammatory drugs (DMARDs) and hand dominance were recorded.

Results: DAS-28 and HAQ scores were high at inclusion and improved thereafter in both women and men. There were no significant differences between sexes at inclusion but women had higher DAS-28 and HAQ at all follow-ups. Women were more often prescribed DMARDs than were men. In both women and men all pain types were significantly lower at follow-up compared to at inclusion and women reported higher pain than men at follow-ups. The pain types differed significantly from each other at inclusion into TIRA, general pain was highest and hand pain during rest was lowest. There were no significant differences in hand pain related to hand dominance or between right and left hands.

Conclusions: Disease activity, disability and pain were high at inclusion and reduced over the first year. Despite more DMARDs prescribed in women than in men, women were more affected than were men. General pain was highest and not surprisingly hand pain during active grip testing was higher than hand pain during rest that was lowest in both sexes. Although our cohort was well controlled, it was evident that hand pain remains a problem. This has implications for rehabilitation and suggests potential ongoing activity limitations that should continue to receive attention from a multi-professional team.

  • Implications for Rehabilitation
  • General pain and hand pain remain a problem in RA despite today's early intervention and effective disease control with new era biologics.
  • The extent of hand pain evidenced in our work gives a more detailed and comprehensive account of pain status.
  • Higher hand pain during active grip testing than that during rest indicates a potential relationship to ongoing activity limitation.
  • Hand pain assessment can help guiding multi-professional interventions directed to reduce hand pain and thereby probably reduce activity limitations.

Abstract [en]

The purpose of this study is to examine whether the neural correlates of lexical expectations could be used to predict speech in noise perception. We analyse mag-netoencephalography (MEG) data from 20 normal hearing participants, who read a set of couplets (a pair of phrases with rhyming end words) prior to the experiment. During the experiment, the participants are asked to listen to the couplets, whose intelligibility is set to 80%. However, the last word is pronounced with a delay of 1600 ms (i.e. expectation gap) and is masked at 50% of intelligibility. At the end of each couplet, the participants are asked to indicate if the last word was cor-rect, i.e. corresponding to the expected word. Given the oscillatory characteristics of neural patterns of lexical expectations during the expectation gap, can we predict the participant’s actual perception of the last word? In order to approach this re-search question, we aim to identify the correlation patterns between the instances of neural pre-activation, occurring during the interval of the expectation gap and the type of the given answer. According to the sequential design of the experiment, the expectation gap is placed 4400 ms prior to the time interval dedicated to the participant’s answer. Machine Learning approach has been chosen as the main tool for the pattern recognition.

Abstract [en]

Whether cognitive load and other aspects of task difficulty increases or decreases distractibility is subject of much debate in contemporary psychology. One camp argues that cognitive load usurps executive resources, which otherwise could be used for attentional control, and therefore cognitive load increases distraction. The other camp argues that cognitive load demands high levels of concentration (focal task engagement), which suppresses peripheral processing and therefore decreases distraction. In this article, we employed an functional magnetic resonance imaging (fMRI) protocol to explore whether higher cognitive load in a visually-presented task suppresses task-irrelevant auditory processing in cortical and subcortical areas. The results show that selectively attending to an auditory stimulus facilitates its neural processing in the auditory cortex, and switching the locus-of-attention to the visual modality decreases the neural response in the auditory cortex. When the cognitive load of the task presented in the visual modality increases, the neural response to the auditory stimulus is further suppressed, along with increased activity in networks related to effortful attention. Taken together, the results suggest that higher cognitive load decreases peripheral processing of task-irrelevant information which decreases distractibility as a side effect of the increased activity in a focused-attention network.

Abstract [en]

Workplaces are one of the most important regular meeting places in society. The aim of this study was to use simulation experiments to examine the impact of different workplace cultures on influenza dissemination during pandemics. The impact is investigated by experiments with defined social-mixing patterns at workplaces using semi-virtual models based on authentic sociodemographic and geographical data from a North European community (population 136 000). A simulated pandemic outbreak was found to affect 33% of the total population in the community with the reference academic-creative workplace culture; virus transmission at the workplace accounted for 10.6% of the cases. A model with a prevailing industrial-administrative workplace culture generated 11% lower incidence than the reference model, while the model with a self-employed workplace culture (also corresponding to a hypothetical scenario with all workplaces closed) produced 20% fewer cases. The model representing an academic-creative workplace culture with restricted workplace interaction generated 12% lower cumulative incidence compared to the reference model. The results display important theoretical associations between workplace social-mixing cultures and community-level incidence rates during influenza pandemics. Social interaction patterns at workplaces should be taken into consideration when analysing virus transmission patterns during influenza pandemics.
