Benchmarking Community-Based Couple Therapy: Considering Measurement Reactivity.

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Couple therapy demonstrates efficacy in controlled trials, but real-world effectiveness varies.
• Naturalistic studies often yield less consistent results than randomized clinical trials.
• A need exists for standardized methods to evaluate community-based couple therapy outcomes.

Purpose of the Study:

• To benchmark the effectiveness of community-based couple therapy against efficacy treatments.
• To compare real-world couple therapy outcomes with findings from randomized clinical trials.
• To introduce a novel benchmarking approach for psychotherapy research.

Main Methods:

• Utilized a benchmarking approach with the largest couple therapy sample to date (N=3,347 couples).
• Collected weekly symptomology ratings using the Outcome Questionnaire (OQ-45.2).
• Compared effect sizes from community clinics to established efficacy benchmarks.

Main Results:

• Community couple therapy effect sizes were initially smaller than efficacy studies.
• Effect sizes became comparable after accounting for measurement reactivity.
• This is the first benchmarking study for community-based couple therapy.

Conclusions:

• Benchmarking provides a meaningful way to compare couple therapy outcomes across different settings.
• Measurement sensitivity significantly impacts the interpretation of psychotherapy effectiveness.
• This approach aids in evaluating community-based psychotherapy studies and understanding real-world therapy impact.
