Objective: This study explores in cognitive-behavioral therapy (CBT) for generalized anxiety disorder (GAD) to what degree therapists’ perceptions of their patients as interpersonally challenging (IC) is explained by the therapist or patient effects, if baseline patients’ characteristics predict IC, and if IC is related to outcome. Method: Eighty patients diagnosed with GAD and treated by 20 therapists with 16 sessions of CBT were randomized to two different implementation conditions. Patients completed baseline measures of depression, anxiety, interpersonal problems, and interpersonal strengths. The therapists completed a single-item assessing IC session-by-session. As an outcome, patients completed a worry measure at baseline, session 5, session 10, and posttreatment. Results: Multilevel models showed meaningful therapist effects, explaining 18% of IC variance. Interpersonal strengths were the only baseline predictor significantly and negatively associated with IC during treatment. Structural equation models showed significant negative IC effects on subsequent patient worry during therapy. Conclusions: IC might represent a risk factor for psychotherapy outcome. Patient interpersonal strengths at baseline may buffer therapists perceiving their patients as ICs. The therapist effects on IC suggest that CBT clinicians treating GAD might benefit from identifying cases that are interpersonally challenging for them and reflecting about what might trigger that perception.
