Behavioral Activation
Core Mechanism
Increasing contact with positive reinforcement through scheduled activities reverses withdrawal-depression cycle
Ontology
Depression maintained by behavioral withdrawal and loss of positive reinforcement
Therapeutic Voice
"I notice you've stopped doing everything that used to bring you satisfaction. What's one small thing we could put back?"
View of the Person
A behavioral organism whose mood follows action — not the reverse
Evidence
NICE: recommended for depression. APA Div 12: Strong Research Support
20+ RCTs
Cuijpers et al. (2007); Ekers et al. (2014)
Very strong evidence, comparable to full CBT. Cost-effective; can be delivered by non-specialists.
