Abstract [en]

Background: Chronic pain is a major health problem and more knowledge is needed regarding the interference of pain on behaviors in different life domains. Clinically useful and statistically sound pain interference measures are highly important. Studies on youths have shown that the Pain Interference Index (PII) is a reliable and valid instrument that is sensitive to change following behavioral treatment. This measure may also have utility for adults, but no study has so far evaluated the statistical properties of the PII for long-standing pain in adults. Methods: Data were collected from 239 consecutive adults with non-specific chronic pain referred to a tertiary pain clinic. We investigated the factor structure of items using a principal component analysis. Cronbachs alpha was calculated to assess internal consistency. The questionnaires ability to predict levels of, e.g., disability was analyzed by means of regression analyses. Results: Analyses illustrated the adequacy of a one-factor solution with six items. Cronbachs alpha (0.85) suggested a satisfactory internal consistency among items. The PII explained significant amounts of variance in pain disability, physical, and mental health-related quality of life and depression, suggesting concurrent criteria validity. Conclusion: The PII is a brief questionnaire with reliable and valid statistical properties to assess pain interference in adults. Other studies support the reliability and validity of PII for use with youths, and now the PII can be used to analyze the influence of pain on behaviors across age groups. Potentially, the PII can also be used as an outcome measure in clinical trials.

Abstract [en]

Despite demonstrated efficacy of behavioral and cognitive techniques in treating the impact of tinnitus (constant ringing in the ears), little is known about the mechanisms by which these techniques achieve their effect. The present study examined acceptance of tinnitus as a potential mediator of treatment changes on global tinnitus severity in internet-delivered acceptance and commitment therapy (iACT) and internet-delivered cognitive behavior therapy (iCBT). Data from 67 participants who were distressed by tinnitus and who were randomly assigned to 1 of the 2 treatments were analyzed using a multilevel moderated mediation model. We predicted that acceptance as measured with the two subscales of the tinnitus acceptance questionnaire (i.e., activity engagement and tinnitus suppression) would mediate the outcome in iACT, but not in iCBT. Results provided partial support to the notion that mediation was moderated by treatment: tinnitus suppression mediated changes in tinnitus severity in iACT, but not in iCBT. However, inconsistent with the view that the treatments worked through different processes of change, activity engagement mediated treatment changes across both iACT and iCBT. Acceptance is identified as a key source of therapeutic change in behavioral-based treatments for tinnitus.

Abstract [en]

The concept of acceptance has recently received growing attention within tinnitus research due to the fact that tinnitus acceptance is one of the major targets of psychotherapeutic treatments. Accordingly, acceptance-based treatments will most likely be increasingly offered to tinnitus patients and assessments of acceptance-related behaviours will thus be needed. The current study investigated the factorial structure of the Tinnitus Acceptance Questionnaire (TAQ) and the role of tinnitus acceptance as mediating link between sound perception (i.e. subjective loudness of tinnitus) and tinnitus distress. In total, 424 patients with chronic tinnitus completed the TAQ and validated measures of tinnitus distress, anxiety, and depression online. Confirmatory factor analysis provided support to a good fit of the data to the hypothesised bifactor model (root-mean-square-error of approximation = .065; Comparative Fit Index = .974; Tucker–Lewis Index = .958; standardised root mean square residual = .032). In addition, mediation analysis, using a non-parametric joint coefficient approach, revealed that tinnitus-specific acceptance partially mediated the relation between subjective tinnitus loudness and tinnitus distress (path ab = 5.96; 95% CI: 4.49, 7.69). In a multiple mediator model, tinnitus acceptance had a significantly stronger indirect effect than anxiety. The results confirm the factorial structure of the TAQ and suggest the importance of a general acceptance factor that contributes important unique variance beyond that of the first-order factors activity engagement and tinnitus suppression. Tinnitus acceptance as measured with the TAQ is proposed to be a key construct in tinnitus research and should be further implemented into treatment concepts to reduce tinnitus distress.

Abstract [sv]

Har du ett klingande, ringande, tjutande, brusande, surrande, visslande ljud i huvudet eller öronen som påverkar ditt dagliga liv? Ett stort antal personer i Sverige upplever att tinnitus inverkar på deras mående, sömn, koncentrationsförmåga och livskvalitet.Ljudet kan uppfattas störande i ett flertal situationer och ljudmiljöer såsom i tystnad, vid restaurangbesök eller vid samtal. Vissa upplever inte längre samma glädje i aktiviteter som de tidigare uppskattade. Andra känner en oro och frågar sig om deras tinnitus kommer att bli värre, eller om den är tecken på något allvarligt fel.Leva med tinnitus är en självhjälpsbok som bygger på material som arbetats fram och prövats med goda resultat under flera år av forskning och som tillvaratar den senaste utvecklingen inom tinnitusbehandling. Metoderna i boken är hämtade från kognitiv beteendeterapi (KBT) och acceptance and commitment therapy (ACT). Läsaren får arbeta med olika beprövade tekniker och tillägnar sig nya förhållningssätt. Syftet är att tinnitus inte längre ska behöva ta lika stor plats i den enskildes liv.

Abstract [en]

Objective: Our aim in this randomized controlled trial was to investigate the effects on global tinnitus severity of 2 Internet-delivered psychological treatments, acceptance and commitment therapy (ACT) and cognitive behavior therapy (CBT), in guided self-help format. Method: Ninety-nine participants (mean age = 48.5 years; 43% female) who were significantly distressed by tinnitus were recruited from the community. Participants were randomly assigned to CBT (n = 32), ACT (n = 35), or a control condition (monitored Internet discussion forum; n = 32), and they were assessed with standardized self-report measures (Tinnitus Handicap Inventory; Hospital Anxiety and Depression Scale; Quality of Life Inventory; Perceived Stress Scale; Tinnitus Acceptance Questionnaire) at pre-, posttreatment (8 weeks), and 1-year follow-up. Results: Mixed-effects linear regression analysis of all randomized participants showed significant effects on the primary outcome (Tinnitus Handicap Inventory) for CBT and for ACT compared with control at posttreatment (95% CI [-17.03, -2.94], d = 0.70, and 95% CI [-16.29, -2.53], d = 0.68, respectively). Within-group effects were substantial from pretreatment through 1-year-follow-up for both treatments (95% CI [-44.65, -20.45], d = 1.34), with no significant difference between treatments (95% CI [-14.87, 11.21], d = 0.16). Conclusions: Acceptance-based procedures may be a viable alternative to traditional CBT techniques in the management of tinnitus. The Internet can improve access to psychological interventions for tinnitus.

Abstract [en]

Tinnitus is defined as a sound in the ear(s) and/or head without external origin and is a serious health concern for millions worldwide. The aim of the present study was to determine whether Cognitive Behavior Therapy (CBT) is effective in reducing distress associated with tinnitus. Randomized, controlled trials that assessed the efficacy of CBT for tinnitus-related distress in adults were identified by searching electronic databases (PsychINFO, PubMed, the Cochrane Library), and by manual searches. Fifteen studies (total of 1091 participants) were included in the meta-analysis. CBT compared with a passive and active control at post-assessment yielded statistically significant mean effect sizes for tinnitus-specific measures (Hedgess g = 0.70. and Hedgess g = 0.44, respectively). The average weighted pre-to-follow-up effect size for the CBT group suggested that these effects were maintained over time. Smaller but yet statistically significant effects of CBT were found for mood outcome measures. Characteristics of the studies were unrelated to effect sizes. Methodological rigor, publication bias, and a series of sensitivity analyses did not influence the findings. The results suggest that CBT is an effective treatment of tinnitus distress. However, caution is warranted given that few large-scale, well-controlled trials were identified.

Abstract [en]

The study compared the effects of Acceptance and Commitment Therapy (ACT) with Tinnitus Retraining Therapy (TRT) on tinnitus impact in a randomised controlled trial. Sixty-four normal hearing subjects with tinnitus were randomised to one of the active treatments or a wait-list control (WLC). The ACT treatment consisted of 10 weekly 60min sessions. The TRT treatment consisted of one 150min session, one 30min follow-up and continued daily use of wearable sound generators for a recommended period of at least 8h/day for 18 months. Assessments were made at baseline, 10 weeks, 6 months and 18 months. At 10 weeks, results showed a superior effect of ACT in comparison with the WLC regarding tinnitus impact (Cohen's d=1.04), problems with sleep and anxiety. The results were mediated by tinnitus acceptance. A comparison between the active treatments, including all assessment points, revealed significant differences in favour of ACT regarding tinnitus impact (Cohen's d=0.75) and problems with sleep. At 6 months, reliable improvement on the main outcome measure was found for 54.5% in the ACT condition and 20% in the TRT condition. The results suggest that ACT can reduce tinnitus distress and impact in a group of normal hearing tinnitus patients.
