The Effect of Roy Adaptation Model-Based Intervention on Self Concept of Teenage Girls

Background: Self-concept is among the most important factors influencing health, particularly during adolescent years. Mental health in adolescents, social adaptation, and healthy behaviors require coordination and adaptation with physical and mental changes resulting from this period. Objectives: The purpose of the present study was to determine the effect of the Roy adaptation model-based intervention on the self-concept of teenage girls. Methods: This quasi-experimental study was conducted in 2016 on 64 teenage girls with the available random sampling method; subjects were randomly assigned into control and intervention groups. For the intervention group, 12 weeks of intervention were performed as instruction and follow-up. Data were collected before and after intervention using personal information form and a researcher-made questionnaire, including 50 questions of self-concept in teenage girls based on the Roy adaptation model. The validity was examined by content validity, and the reliability was examined by internal consistency with the Cronbach’s alpha of 0.74. Finally, data were analyzed using SPSS 16, descriptive statistics (mean, standard deviation, frequency), and analytical tests (independent t-test, chi-square). The significance level was below 0.05. Results: The average age of participants was 14.2 ± 1.21. Average self-concept before intervention in the control group was 171.31 ± 11.95 and in the intervention group was 165.03 ± 17.82 where no significant difference existed (P = 0.10). Average self-concept after intervention on control group was 176.62 ± 12.18 and in the intervention group was 197.06 ± 10.09, where a significant difference existed (P < 0.001). The results of the independent t-test in research groups after intervention showed that the employment of the Roy adaptation model promoted the average self-concept in teenage girls (P < 0.001). Conclusions: Employment of the designed program, based on the Roy adaptation model, can promote the self-concept of girls regarding transformations during their adolescent years.
