Abstract While Routine Outcome Monitoring (ROM) of change and therapeutic alliance is proving to be a promising way to address the issues of drop-out and client deterioration in psychotherapy, at present ROM is infrequently employed in French-speaking contexts. This study aimed at testing psychometric properties of the French versions of two popular and widely used ROM tools in the Partners for Change Outcome Management System (PCOMS): The Outcome Rating Scale (ORS) and Session Rating Scale (SRS). The project necessitated a multiple study survey with online data collection of clinical and non-clinical samples, to investigate psychometric qualities (including factorial structure of the two scales), using parametric and non-parametric procedures. In addition, we documented, preliminary estimates regarding clinical cut-off and reliable change indices for ORS. Both ORS and SRS have good psychometric properties regarding brevity. Reliability, normative data, a reliable change index and scale thresholds are reported for the French versions. The clinical use of PCOMS appears promising regarding delivering, regulation, and improvement of psychotherapy in French-speaking areas.

Evidence supporting the effectiveness of psychotherapy for health is well-established (Cooper, 2008; Lambert & Ogles, 2004; Wampold & Imel, 2015). The effectiveness of treatment in naturalistic practice can be comparable to the efficacy of psychotherapy assessed in randomized control trials (Shadish, Matt, Navarro, & Phillips, 2000; Minami et al., 2008). Nevertheless, complementary data indicate that not all clients benefit from psychotherapy (approximately 50% terminating service before achieving reliable change). A significant percentage drops out ([~25%] Swift & Greenberg, 2012), and a consistent percentage reports deterioration following care (5% to 10% of adult clients participating in clinical trials (Lambert & Ogles, 2004).

Differences in outcomes between bona fide interventions for a specific problem are generally considered non-significant, while therapists represent an important part of the variance in outcomes (Wampold, 2001; Wampold & Imel, 2015).These differences are incorrectly explained by therapists’ characteristics (level of
