Construct Validation of the Health Enhancement Lifestyle Profile (HELP) with Quality of Life among Community-Dwelling Older Adults

Abstract

ABSTRACTObjective: This study aimed to provide evidence of construct validity of the health enhancement lifestyle profile (HELP) by exploring its relationship with health-related quality of life. Method: Both the HELP and RAND-36 health survey were administered with a sample of 158 community-dwelling older adults. Pearson r and multiple regression were performed to analyze the correlations between different scales of the two instruments. Results: Bivariate correlations between the HELP scale scores and the overall RAND-36 ranged from low to high (r is from 0.39 to 0.69). Multiple regression revealed that five of seven HELP scales served as significant predictors for the RAND-36 (R2 = 0.69, p < 0.0001). The patterns of the multiple correlations persisted even after the inclusion of two potential contributing factors, age and chronic conditions. Conclusion: The construct validity of the HELP was supported. The HELP holds promise as a comprehensive measure for monitoring health promotion and risk behaviors and determining the outcome of lifestyle interventions conducive to quality of life in older adults.
