Routine outcome monitoring (ROM) is the practice of using self- or other report measures to inform treatment by monitoring client symptoms and treatment progress while providing feedback to clinicians and clients. Although ROM has been found to improve therapeutic outcomes and reduce early termination and is considered an evidence-based practice, this essential process is underutilized by clinicians due to philosophical and practical implementation barriers. To improve clinician knowledge and utilization, there have been several recent calls for the study of ROM education and training practices. This paper describes a multiyear study of standardized ROM implementation in a psychology training clinic following a process model. We discuss features of the model and the implementation process including procedures, barriers, facilitators, and outcomes. While initially there were barriers to ROM implementation consistent with the literature, the use of an implementation framework along with evaluation (e.g., clinician feedback, client surveys) helped to address these barriers and improve ROM implementation, resulting in high utilization and compliance rates. The discussion highlights lessons learned and identified facilitators to help aid successful ROM implementation within a training setting. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
