This report delves into the integration of counselling theories, specifically examining the compatibility of Person-Centred Therapy (PCT) and Cognitive Behavioral Therapy (CBT) within the assimilative integration model. It explores the views of humanness, wellness, and the processes of behavior change from both PCT and CBT perspectives, highlighting how their metatheoretical orientations complement each other. The report emphasizes the importance of understanding these theoretical underpinnings to effectively integrate the two approaches, ultimately aiming to enhance counselling practice. It discusses how PCT's developmental and organismic metatheory aligns with CBT's positivism, and how this integration can lead to a more comprehensive understanding of mental health and improved client outcomes. The report also reviews the application of technical eclecticism, and cultural responsiveness in this context. The provided assignment reviews different models of integration, and the views of humanness, wellness and how behaviour changes occur.
