The long-term effect on mental health symptoms and patient activation of using patient feedback scales in mental health out-patient treatment. A randomised controlled trial

•No significant effects from using feedback scales on mental health symptoms.•No significant effects from using feedback scales on patient activation.•This study showed no long-term effects from using PCOMS above that of usual care.

ObjectiveTo investigate the long-term effect on mental health symptoms and patient activation, from using the Partners for Change Outcome Management System (PCOMS) feedback scales in out-patient mental health consultations, compared to not using feedback scales.MethodsAn open parallel-group randomised controlled trial was conducted in a mental health hospital in Norway. Eight therapists treated the intervention group, using two feedback scales, and seventeen therapists treated the treatment as usual group.ResultsSeventy-five patients participated. Six and twelve months after starting treatment there were no significant effects on the primary outcomes mental health symptoms or patient activation. Compared to baseline assessment the PCOMS group had significantly improved their patient activation scores after twelve months.ConclusionWe found no long-term effects from using the PCOMS scales on mental health symptoms or patient activation.Practice implicationsThis study shows that the use of a feedback system does not increase mental health outcomes or patient activation.
