The therapeutic alliance in the cognitive behavioral treatment of pediatric obsessive-compulsive disorder.

Although cognitive-behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD) is considered a first-line treatment, not all youth have a positive treatment response, suggesting need for investigating factors that may enhance or reduce treatment effects. Few studies have investigated predictors of treatment response in pediatric OCD, and there is an absence of studies examining the influence of treatment process variables (e.g., therapeutic alliance [TA]) on treatment outcome. Using a multiple-informant and multiple-time point design, the current study examined the role of the TA in family-based CBT for pediatric OCD. Analyses examined (1) the predictive value of the TA on OCD symptom reduction and (2) whether changes in the TA over time predict treatment response. Findings indicated that (1) stronger child-rated, parent-rated, and therapist-rated TAs were predictive of better treatment outcome and (2) larger and more positive early alliance shifts (as rated by changes in child-rated TA between sessions 1 and 5) were predictive of better treatment outcome. Implications for the treatment of youth with OCD within family-based CBT are discussed.
