We summarise the recent reflections of five thought leaders in the field of routine outcome measurement (ROM) for psychological therapy, and then add our own experience of introducing a national ROM system in the UK. We highlight, in particular, the post-implementation challenge of securing data of sufficient reliability to help inform service quality improvements. We ground our conclusions and recommendations in the rapidly evolving discipline of implementation science, and offer a best practice model for applying research recommendations in practice settings. In this context we portray ROM implementation as significant organizational change that benefits from rigorous process and clearly defined, well-communicated targets.

Using outcome questionnaires as conversational tools helps practitioners focus on change at the individual item level rather than the numeric level. Tracking Responses to Items in Measures helps provide clients and practitioners with feedback on areas of positive change that may be masked by summary score analysis. Exploring the lack of change or deterioration on particular questions helps practitioners to assess extra-therapeutic factors that may be compromising change. Using individual item change profiles as feedback for clients helps validate their progress and reinforce their strengths and self-efficacy.
