Subjects were 120 adolescent girls aged 13-14years studying in the girls' high school that were randomly assigned to intervention and control groups. The data collection tool was the demographic questionnaire and the researcher-made questionnaire consisting of six domains based on the BASNEF model. Validity and reliability of the questionnaires were confirmed before data collections. The educational program was developed based on the BASNEF model in four sessions lasting from 30 to 45min. Data was collected before, immediately and 1month after the educational program and was analyzed via the SPSS software v.18.ResultsNo statistically significant differences were reported between the groups in terms of knowledge (p=0.48), attitude (p=0.94), subjective norms (p=0.17), behavioral intention (p=0.82), enabling factors (p=0.62), and osteoporosis preventive behaviors (p=0.32). Meanwhile, immediately and 1month after the educational program, differences were reported between the two groups in knowledge (p<0.001), attitude (p=0.002, p<0.001), subjective norms (p=0.024, p=0.001), behavioral intention (p<0.001, p=0.001), enabling factors (p<0.001), and osteoporosis preventive behaviors (p<0.001).ConclusionIt is suggested that educational program based on the BASNEF model is used to strengthen the osteoporosis preventive behaviors among adolescent girls.
