Psychometric properties of the health-promoting lifestyle profile (HPLP II) in a sample of Iranian adolescents

Health-promoting behaviors of individuals are important determinants of health status. The objective of this study was to examine the psychometric properties of the Iranian version of health-promoting lifestyle profile II (HPLP II) among adolescent girls. Pender''s Health Promotion Model was the theoretical framework for this cross-sectional study of a sample of 500 high school girls (grade9-11)، in Kashan، Iran. The HPLP II reliability was estimated using the Cronbach''s alpha coefficient and test-retest. Concurrent validity was estimated by performing Pearson’s correlation between the HPLP II، and the 12-item Short Form Health Survey (SF-12)، perceived self-efficacy. In addition confirmatory factor analysis (CFA) was performed in order to evaluate construct validity. The data were analyzed using SPSS v. 18 and LISREL8. 8 programs. The Cronbach’s α coefficient was 0. 86 for the instrument and for subscales ranged from 0. 70 to 0. 77. The correlation between the HPLP II and the SF-12 and perceived self-efficacy were significant as expected. The confirmatory factor analysis yielded a good estimate of fit (χ2=6. 34، df =2، P = 0. 420،NFI = 0. 99، CFI = 0. 99، RMSEA = 0. 066). The psychometric properties of Iranian version of HPLP II showed satisfactory results and now it can be used in studies of health promotion among young adolescents.
