The current study used a dismantling design to investigate the relative efficacy of components of the Partners for Change Outcome Management System (PCOMS; Duncan, 2012). Clients (n = 94) from a university counseling center were randomly assigned to 1 of 3 conditions: PCOMS Full, Outcome Rating Scale (ORS)-only, or Session Rating Scale (SRS)-only and nested within therapists (n = 12). Results from hierarchical linear modeling and a 2-way analysis of variance indicated no statistically significant differences in outcome or rate of change on the Behavior Symptom Checklist-18 (BSI-18; Derogatis, 2001) across all 3 conditions. These findings suggest that using either the ORS or SRS component of the PCOMS may yield equivalent outcomes to that of the full PCOMS. Additional dismantling studies with various populations and settings are needed to further clarify the relative influence of the ORS, SRS, and full PCOMS on client outcomes.
