The authors used a one-group pre-test-post-test design to examine the feasibility and acceptability of an osteoporosis prevention program and the effects of the program on knowledge, health beliefs, self-efficacy; and osteoporosis preventive behaviors in older adults. Participants included 48 older adults who attended a health center in Thailand. Results revealed that the program was feasible and acceptable. A significant improvement in osteoporosis knowledge, health beliefs, self-efficacy, and osteoporosis preventive behaviors occurred. Findings suggest that the program helps older adults incorporate new knowledge and skills into their daily lives and helps them maintain bone health.
