Mechanisms of the Acceptance and Commitment Therapy: A meta-analytic structural equation model

Following the Behavioral Therapy and the Cognitive-Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT) is considered as one of the third wave of behavioral therapies. ACT is based on the relational frame theory, and its therapeutic model includes 6 components (i.e., acceptance, cognitive defusion, self-as-context, committed action, contact with the present moment, values) and psychological flexibility. What is the empirical evidence for these hypothesized components or mechanisms? In recent years, integrating meta-analysis and structural equation modeling, the meta-analytic structural equation model (MASEM) has made it possible to systematically examine the mechanisms of psychotherapy. Compared to the traditional single randomized controlled trial (RCT) studies, the MASEM combines multiple samples to increase statistical power and obtain more robust model estimates. The current study utilized two-stage structural equation modeling (TSSEM) to examine three aspects of the mechanisms of ACT, including: (1) the mediational effects of psychological flexibility and the 6 components, (2) the unique mechanisms of ACT compared to CBT, and (3) the generalizability of these mechanisms to internet-based ACT interventions.
