Validity and reliability evidence of Health-Promoting Lifestyle Profile (HPLP)-II among nursing students: A confirmatory factor analysis

Background: Health-promoting behaviors are an essential aspect of health promotion, especially for nursing students. However, studies to measure health-promoting behaviors among nursing students remain scarce. The Health-Promoting Lifestyle Profile-II questionnaire may be used to assess the HPB among nursing students. Aim: To determine psychometric properties of the Health-Promoting Lifestyle Profile-II scale among under-graduate nursing students.Methods: As part of a major cross-sectional study regarding health-promoting behaviors of 866 undergradu-ate nursing students, exploratory and confirmatory factor analyses were conducted to assess the validity and reliability evidence of the Health-Promoting Lifestyle Profile-II questionnaire. The participants completed an online survey using the original 6-factor model Health-Promoting Lifestyle Profile-II.Results: The exploratory factor analysis provided a novel 12-factor model for Health-Promoting Lifestyle Pro-file-II. The 12-factor model demonstrates high internal consistency with a Cronbach's alpha of = .929. The confirmatory factor analysis demonstrates a goodness-of-fit index: x2 (1208) = 6939.04, p <= .01, Root Mean Square Error of Approximation = .074, Goodness-of-fit Index = .76, Adjusted Goodness-of-fit Index =.72, the Parsimony Goodness-of-fit Index =.67 and the Comparative Fit Index .76, with x2 and degrees of freedom ratio of 5.74. The 12-factor model shows a better fit compared to the original 6-factor Health-Promoting Life-style Profile-II.Conclusions: As emerging members of health care team, nursing students must project themselves to be models of health promotion. While the Health-Promoting Lifestyle Profile-II shows strong evidence of reli-ability and validity among nursing students, the researchers recommend conducting more studies on health -promoting behaviors using the 12-factor model on different population groups.Published by Elsevier Inc. on behalf of Organization for Associate Degree Nursing.
