Concepts from the ITHBC were used to develop an intervention related to the prevention or attenuation of osteoporosis (1R15NR009021). A description of the intervention is provided as an example of a theory-based intervention. The intervention was designed to foster health behavior change, specifically osteoporosis prevention, by enhancing knowledge and beliefs, facilitating development of self-regulation skills and beliefs, and enriching social facilitation. The intervention is delivered electronically and enhances, not eliminates, individualized care.
