Abstract
Background: Lifestyle choices and individuals’ behaviors have the potential to influence
health and improve the quality of life. Objectives: The purpose of this study was to develop
and psychometrically test an instrument for measuring healthy lifestyle in Iranian adolescents.
Materials and Methods: A comprehensive literature review related to health‑promoting lifestyles
was used to identify potential scale items. Data were collected from 797 school students. Construct
validity was analyzed using exploratory factor analysis. Confirmatory factor analysis (CFA) was
used to cross‑validate. Results: Nine factors emerged that explained 59.8% of the variance in
the 43 items. Cronbach’s a coefficient Healthy Lifestyle Questionnaire was r=0.82. After the
model was modified, the fit indices indicated that the data were an adequate‑to‑good fit to the
proposed models. Conclusions: The current study provides some support to the internal and
external validity of the healthy lifestyles questionnaire for Iranian adolescents.
