Health Status in Adults With Chronic Conditions: Intervention Strategies for Improving Patient-Reported Outcomes.

This literature review analyzes 418 articles from 2 periods (2000-2010 and 2011-2017) to provide interpretative guidelines for the change in physical (PCS) and mental component summaries (MCS) of well-established patient-reported measures (MOS SF-36 V1, HOS SF-12, VR-36, and VR-12). The magnitude of the intervention effects was calculated using baseline and follow-up data. Results were similar across the 2 periods, although the effects of social and behavioral interventions are less consistent and are smaller for PCS. Both single interventions and multicomponent interventions met the moderate to large effect size criterion for PCS and MCS.
