Therapeutic Alliance, Attendance, and Outcomes in Youths Receiving CBT or Client-Centered Therapy for Anxiety.

Objective: Positive associations between therapeutic alliance and outcome (e.g. youth symptom severity) have been documented in the youth anxiety literature; however, little is known about the conditions under which early alliance contributes to positive outcomes in youth. The present study examined the relations between therapeutic alliance, session attendance, and outcomes in youths ( N  = 135; 55.6% female) who participated in a randomized clinical trial testing the efficacy of cognitive-behavioral therapy or client-centered therapy for anxiety.

Method: We evaluated a conceptual model wherein: (1) early alliance indirectly contributes to positive outcomes by improving session attendance; (2) alliance-outcome associations differ by intervention type, with stronger associations in cognitive-behavioral therapy compared to client-centered therapy; and (3) alliance-outcome associations vary across outcome measurement timepoints, with the effect of early alliance on outcomes decaying over time.

Results: Contrary to hypotheses, provider ratings of early alliance predicted greater youth-rated anxiety symptom severity post-treatment (i.e. worse treatment outcomes). Session attendance predicted positive youth-rated outcomes, though there was no indirect effect of early alliance on outcomes through session attendance.

Conclusions: Results show that increasing session attendance is important for enhancing outcomes and do not support early alliance as a predictor of outcomes.
