The micro-process rating system for psychotherapeutic interventions - CBT (RPI-CBT): development and validation

OBJECTIVE: Psychotherapy process research examines what happens within therapy sessions to clarify how therapeutic change unfolds, a scope expanded through modern observational methods. Building on this development, the rating system systematically identifies cognitive-behavioral interventions at the micro-process level, including their duration, and frequency. METHOD: to assess the inter-rater reliability. Descriptive analyses were conducted to illustrate which interventions were captured and how they could be differentiated. RESULTS: = .499 - .892). Primarily, interventions from early therapeutic phases were identified and clearly distinguishable from one another. CONCLUSION: Overall, the RPI-CBT emerged as a reliable rating system capable of identifying and differentiating cognitive-behavioral interventions, although not all interventions were captured.
