Therapist affiliation and hostility in cognitive-behavioral therapy with and without motivational interviewing for...

Although therapist supportive, rather than directive, strategies have been particularly indicated during client resistance, little systematic research has examined how therapists responsively navigate resistance in different therapy approaches and how this responsiveness is related to outcome.

In the context of disagreement episodes in cognitive-behavioral therapy (CBT) for generalized anxiety disorder (GAD; Westra, H. A., Constantino, M. J., & Antony, M. M. Integrating motivational interviewing with cognitive-behavioral therapy for severe generalized anxiety disorder: An allegiance-controlled randomized clinical trial. Journal of Consulting and Clinical Psychology, 84(9), 768-782. https://doi.org/10.1037/ccp0000098, 2016), the present study examined (1) the degree to which therapist management of resistance differed between therapists trained in CBT integrated with motivational interviewing (MI-CBT; i.e., training centered on the responsive management of resistance) and therapists trained in CBT-alone, and (2) the impact of specific therapist behaviors during disagreement on client worry outcomes immediately posttreatment and 1-year posttreatment. Episodes of disagreement were rated used the Structural Analysis of Social Behavior (Benjamin, L. S. Structural analysis of social behavior. Psychological Review, 81(5), 392-425. https://doi.org/10.1037/h0037024, 1974).

Therapists trained in MI-CBT were found to exhibit significantly more affiliative and fewer hostile behaviors during disagreement compared to those trained in CBT-alone; both of these, in turn, were found to mediate client 1-year posttreatment outcomes, such that increased affiliation during disagreement was associated with improved outcomes.

This study highlights the value of training therapists in the responsive detection and management of resistance, as well as the systematic integration of MI into CBT.
