RESUMO
BACKGROUND: Health-promoting lifestyle is receiving increasing attention concerning its prominent role in healthcare. This study examined to adapt the health-promoting lifestyle profile II culturally and to assess its psychometric properties. METHODS: In this cross-sectional study, content validity was established using translation and back-translation procedures, pilot testing of the instrument, and getting views of the expert panel. Concurrent validity was estimated with Pearson's correlation between the HPLP II, the quality of life (SF-12), self-efficacy variables, and demographic variables. Construct validity was evaluated by confirmatory factor analysis (CFA). Sample size for CFA included 500 people. HPLP II reliability was estimated with Cronbach's alpha coefficients. RESULTS: The content validity Index (CVI) surpassed 0.80 for the HPLP II and for four subscales. The CFA four-factor model represented an acceptable fit. Their factor loadings was more than 0.40. Correlations between the HPLP II and the subscales were acceptable. The relationships between the HPLP II, self-efficacy, SF-12 domain scores, and demographic variables were also significantly positive. Cronbach's α coefficient was 0.86 for the HPLP II and for the subscales ranged from 0.70 to 0.77. CONCLUSION: The shortened HPLP II had satisfactory psychometric properties. The revised 34-item four-factor model had perfect fit. It can be used to measure health-promoting lifestyle in the Iranian female adolescents' population.
RESUMO
PURPOSE: To examine the preliminary psychometric properties of the Chinese health-promoting lifestyle profile II (HPLP II) among Taiwanese women. METHODS: We conducted a secondary analysis of cross-sectional data from 137 middle-aged women in southern Taiwan. HPLP II reliability was estimated with Cronbach's α coefficient, and concurrent validity was estimated with Pearson's correlation between the HPLP II, the World Health Organization's abbreviated Quality of Life assessment (WHOQOL-BREF), perceived health, and demographic variables. Confirmatory factor analysis (CFA) evaluated construct validity. RESULTS: Initial CFA using a six-factor measurement model aligned with the original HPLP II, excepting the factor loading of one subsequently excluded item. CFA of the revised 51-item HPLP II yielded a good estimate of fit. Correlations between the revised instrument and the six subscales were acceptable >0.7. The Cronbach's α coefficient surpassed 0.7 for the revised instrument and six subscales ranged from 0.71 to 0.91. The relationships between the 51-item instrument, perceived health, WHOQOL-BREF domain scores, and demographic variables were also significantly positive. CONCLUSIONS: The revised HPLP II scale is appropriate to measure the health-promoting lifestyles of Taiwanese women.
