Abstract

Introduction: Healthy lifestyle behaviors are at the core of maintaining health. This study analyzed the psychometric properties of the 16-item healthy lifestyle beliefs (HLB) scale that measures a person's beliefs about their ability to live a healthy lifestyle.

Method: Descriptive statistics, exploratory factor analysis, confirmatory analysis, and measurement invariance were conducted for this study.

Results: Cronbach alpha was 0.894. The Exploratory factor analysis scree plot identified two factors with eigenvalues greater than one. All factor loadings were greater than 0.40 and no items cross-loaded. A two-factor solution was retained for Confirmatory factor analysis. The measurement invariance results suggested that there was no gender difference in HLB regarding factor structure, factor loading, threshold, and residual variances.

Discussion: The HLB scale was found to have adequate internal consistency and fit with the data. Findings show it is valid and acceptable for both boys and girls.

Trial registration: ClinicalTrials.gov NCT01704768.

Keywords: Adolescent; health; surveys and questionnaires.
