Self-efficacy, motivation, social support, and alliance as predictors of youth psychotherapy outcomes in usual care.

Objective: We examined how youth self-efficacy, motivation for treatment, social support, and therapeutic alliance relate to psychotherapy outcomes of patients receiving services at outpatient community clinics. We hypothesized that (1) these variables would increase throughout the course of therapy, (2) baseline scores would predict initial ratings of distress, (3) baseline scores would predict the rate of change in symptoms throughout treatment, and (4) changes in these variables would be associated with symptom change over the course of treatment.

Method: Participants included 150 adolescents at community outpatient treatment centers. Data was collected prior to beginning treatment, and every three weeks afterward until termination. We used hierarchical linear modeling (HLM) to address our hypotheses.

Results: We found that (1) youth ratings of self-efficacy, social support, and motivation increased throughout treatment, (2) initial self-efficacy and social support were associated with initial levels of distress, (3) ratings of youth self-efficacy at intake predicted its rate of change over therapy, and (4) changes in all variables during therapy were related to lower distress at termination.

Discussion: Results suggest that these variables may affect the trajectory and course of treatment in community-based treatment settings. These results may have implications for treatment planning to maximize treatment effectiveness.
