This article provides meta-analyses of the relation between goal consensus and collaboration and individual psychotherapy outcome using studies published in English between 1978 and June 2017. Inclusion criteria involved (a) a measure of psychotherapy outcome, (b) a measure of goal consensus and/or collaboration, (c) a group design, (d) adult patients (aged 18 years or older), and (e) a reported effect or statistic that could be converted to an effect size. For the 54 studies (N ϭ 7,278) of goal consensus and outcome, the result was r ϭ .24 (95% confidence interval [CI] [.19, .28]) or d ϭ .49, representing a medium effect. For the 53 studies (N ϭ 5,286) of patient-therapist collaboration and outcome, the result was r ϭ .29 (95% CI [.24, .34]) or d ϭ .61, another medium effect. In all, 21 studies (N ϭ 2,081) of therapist collaboration and outcome yielded an omnibus effect of .26 (95% CI [.18, .35]) or d ϭ .54. Results suggest patient-therapist goal consensus and collaboration enhance psychotherapy outcome. The article concludes with research limitations, diversity considerations, and therapeutic practices. Limitations of the studies included a dearth of diverse samples, assessment of goal consensus and/or collaboration at a single time during treatment, failure to relate measures to outcome, and analyses that do not permit causal conclusions. Research suggests that therapists seek input from patients to form and effect treatment goals and plans, provide patients with regular feedback, and seek their involvement throughout therapy.
Clinical Impact StatementQuestion: This article uses three meta-analyses to address the relation of patient-psychotherapist goal consensus and collaboration to psychotherapy outcome. Meaning: Clinicians could use the study findings to achieve better results for their patients. Findings: Results suggest that when therapists and patients agree on psychotherapy goals and actively work together, patients tend to have more positive treatment outcomes. Next Steps: Future research that examines goal consensus and collaboration throughout psychotherapy with ethnically diverse patients would add to our understanding of these therapy processes.
