Benchmarking Community-Based Couple Therapy: Considering Measurement Reactivity

Couple therapy has been shown to be effective in randomized clinical trials; however, results from naturalistic couple therapy have been less consistent. This study utilized a benchmarking approach to compare the effectiveness of couple therapy in a community-based setting with findings from efficacy treatments, such as treatment within randomized clinical trials. The current study is the largest couple therapy sample published to date (N = 3,347 couples). Clients in couple therapy were asked to provide initial and weekly ratings of symptomology on the Outcome Questionnaire (OQ-45.2). We found that treatment effect sizes found at community clinics were smaller than efficacy studies (i.e., the benchmark). However, when taking into account measurement reactivity, the effect sizes were comparable. This is the first benchmarking study for community-based couple therapy, allowing for meaningful comparisons and understanding of outcomes in real-world couple therapy. Implications for the field are offered in terms of evaluating community-based psychotherapy studies with benchmarking for couple therapy. Results of this study provide clinicians and researchers a way to meaningfully compare couple therapy outcomes, accounting for differences in community-based practices and randomized clinical trials. This benchmark also underscores the impact of measurement sensitivity, an issue commonly overlooked in psychotherapy research and practice.
