Osteoporosis Health Belief Scale (OHBS) and the Osteoporosis Self-Efficacy Scale (OSES) in healthy postmenopausal women and older men. METHODS: OHBS and OSES measures were collected before intervention in two longitudinal randomized clinical trials designed to study how receipt of personal dual energy x-ray absorptiometry (DXA) information influences osteoporosis preventing behavior (OPB). A series of models was estimated, first establishing fit of a single-group 9-factor model, and then testing nested multi-group models specifying the equivalence of factor loadings, factor means, and factor covariances across the two

gender groups. RESULTS: ESEM analyses demonstrated: (a) factor loading equivalence across the two samples for the set of 9 factors, as Selleckchem Fludarabine indicated by a non-significant nested chi-square test, SB-scaled Δχ2 (405) = 430.076, p = .1874, with additional evidence provided by statistically significant (p < .001) factor profile similarity indices ranging from .62 to .98; (b)significant latent factor mean differences between the two samples, with men having higher levels BCKDHA of exercise self-efficacy, health motivation and perceived barriers to calcium, and lower levels of perceived osteoporosis susceptibility and seriousness; and (c) equivalence of factor covariance relationships in the two samples. CONCLUSIONS: Discussion addresses

the implications of establishing measurement invariance, benefits of the ESEM approach, and conceptual explanations and nursing implications for the observed differences in latent factor means for behavior change.

While many groups suggest DXA in men, there is no approved screening code.
