A survey of the effect of an information-motivation-behavioral model-based intervention on university students’ osteoporosis knowledge, health beliefs, and self-efficacy

This randomized controlled trial investigated the effectiveness of a Healthy Living Awareness Program for the Prevention of Osteoporosis based on the Information-Motivation-Behavioral Skills Model (HLAPPO-IMB) in university students [intervention group (<i>n</i> = 43), control group (<i>n</i> = 44)]. The intervention group completed the online training to prevent osteoporosis in the information stage of the IMB. In the motivation stage, the researchers texted (WhatsApp) the intervention group spot and reminder notifications concerning the prevention of osteoporosis. They also provided them with telephone counseling. In the final stage, the researchers evaluated whether the intervention group participants developed target behavioral skills. The intervention group had significantly higher mean posttest and follow-up Osteoporosis Knowledge Test scores than the control group (respectively, <i>r =</i> .519, <i>r =</i> .513, <i>p <</i> .001), indicating a large effect size in the posttest and follow-up test. There was no significant difference in pretest and follow-up Osteoporosis Health Belief Scale, Osteoporosis Self-Effective Scale, and International Physical Activity Questionnaire-Short Form scores between the groups (<i>p ></i> .05). The results showed that the HLAPPO-IMB helped the intervention group participants expand their knowledge of osteoporosis. However, it did not improve their self-efficacy in doing weight-bearing exercises, taking calcium, and engaging in physical activity.
