Presentation
Behavioral Activation (BA) is a therapeutic approach for depression derived from the behavioral component of CBT. Initially a component of Beck's cognitive therapy, it was developed as a standalone treatment in the 2000s by Christopher Martell, Sona Dimidjian and Neil Jacobson at the University of Washington, after studies showed the behavioral component alone was as effective as full CBT for depression.
The fundamental principle is that depression is maintained by a behavioral vicious cycle: depressed mood leads to withdrawal from rewarding activities, reducing positive reinforcement, which worsens mood. BA breaks this cycle by reversing the logic: act first, mood improvement will follow ('outside-in' rather than 'inside-out').
Founders: Christopher Martell, Sona Dimidjian and Neil Jacobson, University of Washington
Core Principles
BA rests on the reinforcement model of depression: when a person reduces activities, they lose pleasure, accomplishment and social connection sources that normally maintain stable mood. BA identifies this avoidance pattern and replaces it with progressive engagement in targeted activities.
The TRAP/TRAC technique is a central tool: identify the Trigger → Response → Avoidance Pattern, then transform it into Trigger → Response → Alternative Coping.
Main Indications
- Major depression (primary indication)
- Chronic and recurrent depression
- Mild to moderate depression
- Burnout with depressive component
- Complicated grief with social withdrawal
- Agoraphobia with marked behavioral avoidance
Session Overview
Treatment comprises 8 to 16 weekly sessions of 50 minutes. The first session covers psychoeducation on the behavioral model of depression and introduces the activity log (daily activity tracking with mood rating).
Subsequent sessions include: activity log review, avoidance pattern identification, next week's activity planning (gradual progression), problem-solving for overcoming obstacles, and outcome evaluation.
Variations and Sub-techniques
- Martell's behavioral activation (BATD protocol)
- Brief behavioral activation (6-8 sessions)
- Group behavioral activation
- Online behavioral activation
- Behavioral activation adapted for elderly
Contraindications
- Manic or hypomanic episode
- Severe physical exhaustion requiring rest first
- Depression with psychotic features
