Abstract
The purpose of this study was to examine the effect of a six-month lifestyle-based intervention on health-related quality of life (HRQOL) in older adults with hypertension. A secondary analysis of a randomized controlled trial was conducted to test the differences between the intervention and control groups on HRQOL (N=196). The results indicated that there were no statistically significant differences between the intervention and control groups on change in HRQOL, but the final regression models were statistically significant. SF-36 mental component summary (MCS) score at baseline, stress at baseline, and change in stress were significant predictors for predicting change in the SF-36 MCS. SF-36 physical component summary (PCS) at baseline and change in stress were significant predictors for predicting change in the SF-36 PCS. The findings suggest that the development of an effective intervention in improving HRQOL should be considered within individual, interpersonal, societal, and cultural factors for future research and clinical practice.

SF-36 physical component summary (PCS) at baseline and change in stress were significant predictors for predicting change in the SF-36 PCS. e findings suggest that the development of an effective intervention in improving health-related quality of life (HRQOL) should be considered within individual, interpersonal, societal, and cultural factors for future research and clinical practice
Few research studies tested the effects of lifestyle interventions in older adults with hypertension. e current study performed secondary data analysis to investigate the effect of a lifestylebased intervention on HRQOL in this population
Conceptual Framework and Hypotheses e conceptual framework guiding the current study was derived from the Social Cognitive eory [29] and literature review. is study assumes that there is a relationship between person, environment, and the outcome (e.g., HRQOL)
Summary
E purpose of this study was to examine the effect of a six-month lifestyle-based intervention on health-related quality of life (HRQOL) in older adults with hypertension. Few research studies tested the effects of lifestyle interventions in older adults with hypertension. Lifestyle-based interventions would significantly improve changes in stress (person), social support (environment), and HRQOL (outcome). E purpose of this study was to test the effects of a 6month lifestyle-based intervention on HRQOL in older American adults with hypertension, accounting for stress and social support as mediating variables. After receiving a 6-month lifestyle-based intervention, the intervention group was hypothesized to significantly improve in person (stress) and environment (social support) (H1) and outcome (HRQOL) (H2) in older adults with hypertension from pretest (baseline) to posttest (6 months) compared to the control group
