The effect of teaching puberty health concepts on the basis of a health belief model for improving perceived body image of female adolescents: a quasi-experimental study

BACKGROUND: As children approach adolescence, they focus increasingly on their appearance and physical attraction due to teenage body-image. Teaching the concepts of adolescent health changes an individual’s attitudes towards parts of the body. The health belief model (HBM) is one of the significant pedagogic models in health education. According to this model, the individual’s decision and motivation for adopting healthy behaviors depends on three separate categories “personal perception, adaptive behaviors, and probability of performing that action or behavior”. This study investigated the effect of teaching puberty health concepts on the basis of a HBM on perceived body image in female adolescents. METHODS: A quasi-experimental research design was used in the study. This study was conducted with 60 sixth grade girls in state elementary schools in Yazd, Iran, that were selected with cluster sampling method and assigned randomly into experimental and control groups. The experimental group were educated in the school during eight 45-min sessions based on the HBM, whereas the control group were educated using the traditional lecturing method. The data were collected with demographic and self-body image questionnaires completed before and after intervention. The data were analyzed with SPSS16 using analysis of covariance (ANCOVA). RESULTS: The mean age of the participants was 12.16 ± 0.74 years. The findings showed that “perceived body image” and “students’ self-attitude” improved significantly after intervention; yet, no significant difference was found between the subscales “attitudes towards weight” and “satisfaction with various parts of the body”. CONCLUSION: The results of the study confirmed the efficacy and efficiency of teaching puberty health on the basis of the HBM on improving perceived body image in female adolescents.
