Objective: Prior studies of Cognitive Behavioral Therapy (CBT) have focused on the quantity and quality of clients' homework completion and only rarely have considered the role of therapist competence.
Methods: The present study examined (a) therapist competence across the entire process of integrating homework into CBT, including the review, design, and planning of tasks; (b) homework engagement, including client appraisals of the difficulty and obstacles encountered in task completion using the Homework Rating Scale - Revised (HRS-II); (c) pre-post symptom reduction as the index of outcome; and (d) considered client factors such as suicide risk in a community-based trial for adolescent depression. Trained independent observers assessed therapist competence and engagement with homework at two consecutive sessions of CBT for N = 80 young people (Mage = 19.61, SD = 2.60).
Results: Significant complementary mediation effects were obtained; there was an indirect mediation effect of HRS-II Beliefs (b = 1.03, SE B = 0.42, 95% BCa CI [0.35, 2.03]) and HRS-II Perceived Consequences on the Competence-Engagement relationship (b = 0.85, SE B = 0.31, 95% BCa CI [0.39, 1.61]). High levels of suicidal ideation were also shown to moderate this relationship.
Conclusions: The present findings contribute to the growing body of CBT process research designed to examine the complex interrelationships of client and therapist variables, in a manner that reflects the actual process of therapy, and advances beyond studies of isolated predictors of symptom change.
