The purpose of this study was to examine this association in these patients. METHODS: 300 ICU patients were randomized into an exercise program (ExP) or standard of care (SoC). Self-report (SF-36 Physical Function Subscale (SF-36pfs), Functional Performance Inventory-Short Form (FPI-SF)) as well as performance-based (Short Physical Performance Battery (SPPB), skeletal muscle strength) measures were taken at hospital discharge, 2, 4, and 6 months post-enrollment. Partial correlations between self-report and performance-based measures of physical function in each group were calculated. Covariates included age, APACHE III score, and gender. Alpha was set at p < 0.05. RESULTS: At hospital discharge, a significant, but weak, correlation (r = 0.32) was found between the SF-36 and SPPB in the SoC group. At 2 months, weak to moderate correlations were found between self-report and performance measures in both groups. In the SoC group, the SF-36 was significantly correlated with the SPPB (r = 0.47) and muscular strength (r = 0.34); the FPI was significantly correlated with the SPPB (r = 0.64) and muscular strength (r = 0.52. In the ExP group, the SF-36 was significantly correlated with the SPPB (r = 0.61) and muscular strength (r = 0.42); the FPI was significantly correlated with the SPPB (r = 0.54) and with muscular strength (r = 0.28). A similar pattern was seen at 4 and 6 months in both groups. CONCLUSION: Self-report and performance-based measures of physical function appear to assess different constructs at hospital discharge. Following recovery from an ICU stay, these measures become complementary, but indicate different constructs are being assessed. en Wake Forest University acute respiratory failure exercise intensive care unit performance physical function self report THE RELATIONSHIP BETWEEN SELF-REPORT AND PERFORMANCE-BASED MEASURES OF PHYSICAL FUNCTION FOLLOWING AN INTENSIVE CARE UNIT STAY Thesis Berry, Michael J Miller, Gary D Mihalko, Shannon L Health and Exercise Science 2018-05-20 open.access
