Brief Summary:
The aim of this study is to compare the efficacy of an internet-based guided self-help training for chronic tinnitus with a well-established outpatient group therapy and a discussion forum group.

Condition or disease Intervention/treatment Phase
Tinnitus Behavioral: Internet-based guided self-help for tinnitus Behavioral: Cognitive-behavior group therapy for tinnitus Other: Internet discussion forum Not Applicable

Detailed Description:
Chronic tinnitus can result in significant psychological suffering and reduce quality of life. Cognitive behavioral therapy (CBT) has been shown to be effective in decreasing the impairment caused by tinnitus. One recent way delivering CBT is an internet-based self-help intervention. Internet interventions for patients with chronic tinnitus, developed by Swedish scientists, showed promising results (Andersson et al., 2002; Kaldo et al., 2007; Kaldo et al., 2008). The main purpose of this study is to compare the efficacy of this internet-based self-help training for chronic tinnitus with a traditional well-established CBT group treatment and with a discussion forum group in a randomized controlled trial. Secondary goals are a process evaluation of both treatments, the identification of predictors of treatment success, an estimation of the cost-effectiveness of each treatment and the validation of the Tinnitus Cognitions Questionnaire (T-Cog; Hiller & Haerkötter, 2005).

Arm Intervention/treatment
Experimental: Internet-based guided self-help
This self-help training is exclusively provided via Internet over a period of 10 weeks. The treatment is based on the cognitive-behavioral approach and consists of 18 modules with helpful strategies to cope with tinnitus (e.g., applied relaxation, positive imagery, attention shift exercises, cognitive restructuring, sleep management, concentration management,). All modules include an information text, detailed practice instructions, worksheets and homework assignments. At the end of each treatment week, there is an e-mail contact between the participants and their therapist. The participants report on their work with the modules and if they had encountered any problems. The therapist provides feedback, support and recommendations on how to proceed.
Behavioral: Internet-based guided self-help for tinnitus
Internet-based self-help for tinnitus: provided via Internet, duration of 10 weeks

Experimental: Cognitive-behavior group therapy
This well-established, cognitive-behavior group therapy was developed by Hiller and Haerkötter (2005) and consists of 10 weekly group sessions of 90 minutes. The strictly manualized program includes the following components focusing on the special needs of chronic tinnitus patients: Education, relaxation techniques, cognitive restructuring, the role of attentional processes for tinnitus perception, analysis of avoidance behaviors, tinnitus and the health care system as well as relapse prevention. For each session participants receive written materials, exercises and homework assignments to enhance understanding and to transfer the new information into the daily routine.
Behavioral: Cognitive-behavior group therapy for tinnitus
Cognitive-behavior group therapy for tinnitus: weekly group sessions of 90 minutes, duration of 10 weeks

Active Comparator: Discussion forum group
To the participants of the control group the group therapy or the internet-based self-help after waiting time of 10 weeks is offered. During the waiting period participants receive access to a tinnitus online discussion forum.
Other: Internet discussion forum
Tinnitus-specific internet discussion forum over 10 weeks (no therapeutic intervention)

Primary Outcome Measures :
  1. Tinnitus Handicap Inventory (THI; Newman, Jacobson, & Spitzer, 1996; German version: Kleinjung et al., 2007) [ Time Frame: 18 months ]
    The measure assesses tinnitus-related disability and handicap.

  2. MINI-Tinnitus Questionnaire (Mini-TQ; Hiller & Goebel, 2004) [ Time Frame: 18 months ]
    The measure is a short version of the Tinnitus Questionnaire (TQ, Goebel & Hiller, 1998), to assess tinnitus-related psychological distress

Secondary Outcome Measures :
  1. Hospital Anxiety and Depression Scale (HADS-D; Zigmond & Snaith, 1983; German version: Herrmann-Lingen, Buss, & Snaith, 2005) [ Time Frame: 18 months ]
    The measure assesses depression and anxiety.

  2. Insomnia Severity Index (ISI; Bastien, Vallière, & Morin, 2001; German version: Pillmann, 2004) [ Time Frame: 18 months ]
    The measure assesses the quality of sleep (sleep duration, sleep quality and negative impact on daily functioning).

  3. Tinnitus Cognitions Questionnaire (T-Cog; Hiller & Haerkötter, 2005) [ Time Frame: 18 months ]
    The measure assesses dysfunctional beliefs and cognitions regarding the tinnitus.

  4. Tinnitus Acceptance Questionnaire (TAQ; Westin, Hayes, & Andersson, 2008; self-translated) [ Time Frame: 18 months ]
    The measure assesses psychological acceptance of the tinnitus.

  5. Anxiety Sensitivity Index - 3 (ASI-3; Taylor et al., 2007; German version: Kemper, Ziegler, & Taylor, 2007) [ Time Frame: 18 months ]
    The measure assesses the fear of anxiety-related sensations.

  6. Fear Avoidance Questionnaire (FAQ; self-developed measure) [ Time Frame: 18 months ]
    The measure assesses fear-avoidance beliefs and behavior.

  7. Working Alliance Inventory - Short Revised (WAI-SR; Horvath & Greenberg, 1986, 1989; German version: Wilmers et al., 2008) [ Time Frame: 2 months ]
    The measure assesses three aspects of the therapeutic alliance (development of an affective bond, agreement on the tasks of therapy and agreement on the goals of therapy).

  8. Credibility Scale (Devilly & Borkovec, 2000; self-translated and adapted to an intervention for tinnitus) [ Time Frame: 6 months ]
    The scale assesses treatment credibility.

  9. Therapy Expectancy Scale (self-developed) [ Time Frame: baseline ]
    The scale assesses therapy expectancy.

  10. Therapy Satisfaction Scale (self-developed) [ Time Frame: week 10 ]
    The scale assesses treatment satisfaction.

  11. Web Screening Questionnaire for Common Mental Disorders (WSQ; Donker, van Straten, Marks, & Cuijpers, 2009; self-translated German version) [ Time Frame: 3 months ]
    The questionnaire screens for depressive disorder, alcohol abuse/dependence, generalized anxiety disorder, posttraumatic stress disorder, social phobia, panic disorder, agoraphobia, specific phobia, and obsessive-compulsive disorder.
