How they work
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
Problem-Solving Therapy
Core mechanism: Structured problem-solving skills (define, generate, evaluate, implement) counteract hopelessness and behavioral inaction in depression
Ontology: Depression maintained by poor problem orientation (negative appraisal of problems) and deficient problem-solving skills

What each assumes — and misses
Behavioral Activation
Philosophical roots: Skinner (behavior as function of consequences); Lewinsohn (behavioral model of depression); pragmatism (act first, meaning follows)
Blind spots: Addresses behavioral withdrawal but not underlying meaning-making, relational patterns, or trauma
Therapeutic voice: I notice you've stopped doing everything that used to bring you satisfaction. What's one small thing we could put back?
Problem-Solving Therapy
Philosophical roots: Dewey (reflective problem-solving); cognitive-behavioral tradition; D'Zurilla (social problem-solving model); pragmatism
Blind spots: Narrow skill focus may miss emotional depth; assumes problems are solvable — less suited for existential or grief concerns
Therapeutic voice: Let's list every possible solution, even the ones that seem impractical. We'll evaluate them after.
Choosing between them
Behavioral Activation and Problem-Solving Therapy both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
