The purpose of this study is to compare an internet-based behavioral activation program with a physical activation program, as treatments for mild to moderate depression. The added effect of rationale and motivational interviewing will also be studied, as well as the effects of relapse prevention program.
BACKGROUND: Despite their potential as low-threshold, low-cost and high-flexibility treatments of depression, behavioural activation and physical exercise have not yet been directly compared. This study will examine the effects of these interventions, administered via the Internet. The added effect of providing a treatment rationale will also be studied, as well as a relapse prevention program featuring cognitive behavioural therapy components. METHODS/DESIGN: This randomised controlled trial will include 500 participants meeting the diagnostic criteria for major depression, recruited in multiple cycles and randomised to either a waiting list control group with delayed treatment, or one of the four treatment groups: (1) physical exercise without a clear treatment rationale; (2) physical exercise with treatment rationale; (3) behavioural activation with treatment rationale; or (4) behavioural activation without a clear treatment rationale. Post treatment, half of the participants will be offered a relapse prevention program. Primary outcome measure will be the Patient Health Questionnaire 9-item. Secondary measures include diagnostic criteria for depression, as well as self-reported anxiety, physical activity and quality of life. Measurements - done via telephone and the Internet - will be collected pre-treatment, weekly during treatment period, immediately post treatment and then monthly during a 24-month follow-up period. DISCUSSION: The results of this study will constitute an important contribution to the body of knowledge of the respective interventions.

Focus is on physical exercise, motivated by research findings that it has a positive effect on depressive symptoms. An individualized exercise program is constructed, to be followed by the respective participant. A user-friendly pulse watch will be mailed to participants. Exercise is monitored through online self-registration with automated feedback.

Change from baseline in Patient Health Questionnaire (PHQ-9)
The PHQ-9 is the nine item depression scale of the Patient Health Questionnaire. The PHQ-9 is a powerful tool for assisting primary care clinicians in diagnosing depression as well as selecting and monitoring treatment. The PHQ-9 is based directly on the diagnostic criteria for major depressive disorder in the Diagnostic and Statistical Manual Fourth Edition (DSM-IV).
Time frame: Weekly during treatment period of 12 weeks

A behavioral activation program, based on the TRAP-TRAC model according to which suffering individuals are trapped in a vicious circle of avoidance and ever fewer reinforcers, leading to increasing discomfort. To break free of this vicious circle, patients have to replace avoidance patterns with alternative coping strategies. Unlike previous applications of this program done in the U.S., this study will feature an internet-based administration. Approximately 15 minutes of electronic therapist support will be included per week.
A behavioral activation program without TRAP-TRAC rationale, but with some encouragement provided ("Activate yourself and feel better!"). Approximately 15 minutes of electronic therapist support will be included per week.
