Over the past three decades, routine outcome monitoring (ROM), or formal feedback (also called measurement-based care), has emerged as a pivotal advance in psychotherapy. ROM entails the systematic collection of client-reported outcomes to track therapeutic progress and guide clinical decision-making. Since the introduction of “patient focused research” in 1996, ROM has garnered sustained scholarly attention due to its demonstrated efficacy in improving treatment outcomes, reducing client dropout, and bridging the research-practice gap.

In China, preliminary studies have reviewed ROM’s clinical effectiveness and applicability. However, research has largely focused on early-stage developments, with limited attention to its overall effectiveness, practical implementation challenges, and strategies for its adoption. Advances in information technology, accumulating meta-analytic evidence, and the global dissemination of ROM have created both opportunities and challenges, motivating this systematic review of three decades of research. This review addresses three core questions: “When and for whom is ROM effective?”, “What implementation challenges exist?”, and “How can ROM research and practice be effectively promoted in China?”

Evidence from over 60 clinical trials and 11 meta-analyses confirms the positive effect of ROM on treatment outcomes, with effect sizes ranging from small (g =.10) to moderate (g =.49). Variability is influenced by several factors including client feedback system, implementation process, client symptom severity, and clinical context. Only two feedback systems have extensive randomized clinical trial (RCT) support: the Outcome Questionnaire−45 System and the Partners for Change Outcome Management System (PCOMS). These two systems account for 74% of the studies included in the recent meta-analysis. The evidence shows that the PCOMS and the use of additional clinical support tools (CST) yield stronger effects, a larger effect for not-on-track clients and those with moderate baseline symptoms, and studies conducted in the U.S. Conversely, feedback may be less effective, or potentially counterproductive, for clients with severe baseline symptoms.

Challenges in ROM research and practice are multifaceted. Cross-cultural and population-specific evidence is limited, with 97% of trials conducted in Western contexts and sparse evidence for children, adolescents, or group therapy. Quantitative studies have primarily focused on therapists, leaving client contributions underexplored despite ROM’s current client-centered foundation. Research design issues, including researcher allegiance and dual use of measures for intervention and evaluation, may introduce bias, although large-sample trials controlling for these factors still support ROM’s effectiveness.

At the clinical level, therapist fidelity remains a recurrent challenge. Effective ROM requires three interrelated clinical processes: collecting client-reported outcome data, sharing feedback with clients, and acting on the data to guide shared decision-making. Evidence suggests that merely collecting or reviewing feedback without collaborative discussion limits its impact. High-quality application, characterized by integrating feedback data into therapeutic dialogue, is critical for enhancing treatment outcomes.

Barriers to ROM adoption operate across individual, organizational, and cultural levels. Individual-level challenges include client concerns about privacy, perceived burdens and therapists’ attitudes, knowledge, and confidence in using feedback. Organizational constraints encompass limited resources, lack of electronic feedback systems, insufficient training, and weak leadership support. Cultural factors, such as “face” concerns in Chinese contexts, may inhibit therapist engagement, particularly when negative outcomes are perceived to threaten professional authority.

Strategies to enhance ROM’s effectiveness and uptake include rigorous, culturally sensitive research, flexible implementation in group or long-term therapy, and technology-assisted data collection. Adoption is further shaped by culture: in non-Western societies like China, therapists’ concerns about perceived risks or “face concern” may be a more salient barrier to its use, indicating training should prioritize mitigating perceived risks. Finally, systemic policy and clinical guideline support are also essential for routine, institutionally supported ROM implementation, as evidenced by initiatives in the United States.

In summary, ROM represents an evidence-based intervention with substantial potential to enhance psychotherapy outcomes, facilitate early identification of stagnating cases, support individualized treatment, and strengthen therapeutic alliances. Despite preliminary domestic research, widespread implementation faces challenges related to cultural adaptation, therapist training, and organizational support. Future work should consolidate empirical evidence, examine client-centered mechanisms, and develop culturally appropriate strategies and policy frameworks to promote routine feedback-based psychotherapy in China. This review provides a comprehensive overview of ROM’s development, current challenges, and future directions, aiming to advance research and standardize evidence-based psychotherapy practice.
