    Tinnitus is a highly prevalent health condition creating moderate or severe interference on mood, sleep and daily functioning for a group of those affected. The aims of this thesis were 1) to explore the role of acceptance and psychological flexibility in understanding tinnitus interference both experimentally and with a longitudinal design 2) to evaluate the immediate and long-term outcomes of an acceptance based behaviour therapy (Acceptance and Commitment Therapy; ACT) in the treatment of people with tinnitus and, 3) to investigate the relationship between treatment outcome and processes assumed to be the active ingredients of treatment (acceptance and cognitive defusion). Study I (n=47) was an experiment comparing the impact of acceptance to that of thought suppression or a neutral instruction on the ability to maintain attention on an imagery task. Results indicated that participants could benefit from an acceptance strategy when performing the task. Study II (n=47) was a longitudinal trial studying the mediating role of acceptance on the relationship between tinnitus interference at baseline and tinnitus interference, anxiety, life quality, and depression at a seven-month follow-up. Full mediation was found for life quality and depression, and partial mediation for tinnitus interference. Study IV (n=64) was a randomised controlled trial evaluating the immediate and long-term effects of ACT in comparison to those of Tinnitus Retraining Therapy (TRT) and to a wait list control. Results showed that ACT had large immediate effects on tinnitus interference in comparison to wait list, and medium long-term effects in comparison to TRT. Results were also seen on secondary outcome. Self-reported tinnitus acceptance significantly mediated the immediate outcome of ACT. Study III (n=24) was a process study where the video recorded sessions of ACT from study IV were observed and rated with regard to client behaviour. Results showed that in-session acceptance and defusion behaviours rated early in therapy were predictors of sustained positive treatment effects of ACT. These associations continued to be substantial even when controlling for the prior improvement in outcome. This whereas prior symptom change could not predict process variables rated late in therapy. Participants in all trials were chronic tinnitus patients, mainly from different departments of audiology. These findings implicate that 1) acceptance and psychological flexibility may contribute to the understanding of tinnitus interference 2) ACT can reduce tinnitus interference in a group of normal hearing tinnitus patients and 3) acceptance and cognitive defusion are important processes in ACT, related to outcome.Tinnitus är ett mycket vanligt hälsoproblem där en grupp av de drabbade upplever påtagliga besvär såsom påverkan på sömn, välbefinnande och funktionsnivå. Denna avhandlings syften var att 1) utforska den roll acceptans och psykologisk flexibilitet har för förståelsen av tinnitusbesvär såväl experimentellt som med en longitudinell design 2) utvärdera de omedelbara och långsiktiga effekterna av en acceptansinriktad beteendeterapi (Acceptance and Commitment Therapy; ACT) vid behandling av personer med tinnitus samt 3) undersöka relationen mellan behandlingsutfall och processer som antas utgöra behandlingens aktiva komponenter (acceptans och kognitiv defusion). Studie I (n=47) var ett experiment där man jämförde förmågan att bibehålla uppmärksamheten på en mental bild vid tre olika betingelser: acceptans, tankesuppression eller en neutral betingelse. Resultaten indikerade att deltagarna som slumpats till acceptans var hjälpta av denna strategi i genomförandet av uppgiften. Studie II (n=47) var en självrapportstudie med longitudinell design där det undersöktes om acceptans fungerade som en mediator i sambandet mellan tinnitusbesvär i baslinjen och livskvalitet, depression, ångest och tinnitusbesvär vid en uppföljning efter sju månader. För variablerna livskvalitet och depression visade resultaten en fullständig mediation och för tinnitusbesvär en partiell mediation. Studie IV (n=64) var en randomiserad kontrollerad prövning av de omedelbara och långsiktiga effekterna av ACT i jämförelse med Tinnitus Retraining Therapy (TRT) och en väntelistekontrollgrupp. Resultaten visade att ACT hade en stor omedelbar effekt på tinnitusbesvär i jämförelse med väntelistan och en medelstor effekt i jämförelse med TRT. Även sekundära utfallsmått visade på effekter. Utfallet i ACT medierades av självrapporterad acceptans av tinnitus. Studie III (n=24) studerade processer i ACT-behandlingen genom observation och skattning av klientbeteenden under de videoinspelade sessionerna. Resultaten visade att klienternas acceptans- och defusionbeteende under sessioner tidigt i terapin predicerade det långsiktiga utfallet i behandlingen. Dessa samband kvarstod även när man kontrollerade för symtomförbättring fram till den skattade sessionen. Detta medan tidigare symtomförbättring inte predicerade klientbeteende senare i behandling. Deltagare i samtliga studier var patienter med kronisk tinnitus, huvudsakligen rekryterade från reguljär hörselvård. Resultaten från dessa studier indikerar att 1) acceptans och psykologisk flexibilitet kan bidra till förståelsen av tinnitusbesvär 2) ACT kan minska tinnitusbesvär hos en grupp normalhörande patienter 3) acceptans och kognitiv defusion är viktiga processer i ACT vilka är relaterade till behandlingutfallet

    Acceptance of Tinnitus: Validation of the Tinnitus Acceptance Questionnaire

    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

    Does cognitive flexibility predict treatment gains in Internet-delivered psychological treatment of social anxiety disorder, depression, or tinnitus?

    Little is known about the individual factors that predict outcomes in Internet-administered psychological treatments. We hypothesized that greater cognitive flexibility (i.e. the ability to simultaneously consider several concepts and tasks and switch effortlessly between them in response to changes in environmental contingencies) would provide a better foundation for learning and employing the cognitive restructuring techniques taught and exercised in therapy, leading to greater treatment gains. Participants in three trials featuring Internet-administered psychological treatments for depression (n = 36), social anxiety disorder (n = 115) and tinnitus (n = 53) completed the 64-card Wisconsin Card Sorting Test (WCST) prior to treatment. We found no significant associations between perseverative errors on the WCST and treatment gains in any group. We also found low accuracy in the classification of treatment responders. We conclude that lower cognitive flexibility, as captured by perseverative errors on the WCST, should not impede successful outcomes in Internet-delivered psychological treatments
