Reliability and validity of the short-version instrument to measure health promotion for Korean cancer survivors

Purpose The current study tests the validity and reliability of the short version of the Health Promoting Lifestyle Profile II (HPLP-II) when used to measure health promotion for Korean cancer survivors. Methods The survey data were collected from 175 Korean cancer survivors who were diagnosed with breast or colorectal cancer in South Korea. The confirmatory factor analysis (CFA) and structural equation modeling were conducted to examine the construct and criterion validity of the Korean version of the HPLP-II. Results Findings demonstrated that excluding nutrition and stress management, four subscales showed good internal consistency. The three competing models of the HPLP-II were tested to determine the factor structure of the HPLP-II for Korean cancer survivors: (a) the original 6-factor, (b) the modified 4-factor, and (c) the modified 5-factor. The five-factor solution with 23 items was selected for the final model. The criterion-related validity based on the relationships between health promotion and HRQOL was demonstrated. Discussion This study makes an important contribution to understanding the health promotion measure used by Korean cancer survivors. Specifically, this study provides a rationale to investigate the validity of a measure before such measures are used in the different language and cultural groups.
