Psychometric properties of the Turkish version: The Osteoporosis Smoking Health Belief Scale

ABSTRACT

Background: Smoking-related health beliefs regarding osteoporosis may be of use to health professionals in helping those at risk of osteoporosis or those with osteoporosis to reduce or stop smoking. Aims: The aim of the study was to evaluate the psychometric properties of the Turkish version of the Osteoporosis Smoking Health Belief Scale (OSHBS). Design and methods: The methodological study sample consisted of 168 people. Cronbach alpha, Spearman–Brown, Guttman split-half method, item-total subscale correlation, and base and ceiling effects were used for reliability analysis. Validity was examined using content validity, construct validity, and contrasted group comparison. Construct validity was examined using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results: EFA revealed that three factors accounted for 67.36% of the explained variance. CFA validity testing supported the three-factor structure and the construct validity. The Cronbach’s alpha coefficients were 0.91 for the benefit subscale, 0.87 for the barrier subscale, and 0.91 for self-efficacy. Conclusion: The scale was found to be a reliable and valid tool for determining the health beliefs of Turkish people concerning smoking in relation to osteoporosis. Health professionals can use the Turkish version of the OSHBS for research and evaluation of the health beliefs of Turkish people concerning smoking in relation to osteoporosis.
