Abstract
Smoking has a deleterious effect on bone mineral density. Psychometric properties were conducted for 3 smoking cessation subscales of the Osteoporosis Smoking Health Belief (OSHB) instrument: barriers, benefits, and self-efficacy. The instrument was evaluated by 6 nurse researchers, administered to a pilot sample of 23 adult smokers aged 19-39, and to a convenience sample of 59 adult smokers aged 19-84 years attending bingo at churches and community centers. Principal components factor analyses were conducted on the 18 items at both time points and accounted for 65.05% of the variances in the matrix at Time 1 and 71.19% at Time 2. The 3 statistical factors corresponded to the theoretically derived concepts. Cronbach's [alpha]s for benefits of not smoking were .86 at Time 1 and .88 at Time 2; for barriers, .78 at Time 1 and .89 at Time 2; and for self-efficacy, .94 at Time 1 and .96 at Time 2. The test-retest correlations were .68 for benefits, .74 for barriers, and .79 for self-efficacy. Paired t tests showed no significant change over time. The OSHB meets relevant measurement criteria.
