Lessons from a systematic review of effects of multisystemic therapy

Influential Campbell-style systematic review showing that MST effects are substantially smaller and less consistent in INDEPENDENT trials than in developer-led trials. Some Cochrane-quality outcomes were null. Sparked decade-long debate about "developer effect" in evidence-based psychotherapies. Modern reading: MST works modestly in serious delinquent youth, especially with high fidelity, but is not the magic bullet original trials suggested. Must be paired with critical reading when recommending.
