Background: Adolescents need an optimal level of self-efficacy in order to function optimally in different dimensions of their lives. One of the factors that can largely explain why and how self-efficacy is formed in teenagers is codependency. So far, few educational programs and codependency injury treatment models based on lived experiences have been used to strengthen the self-efficacy of adolescents.
Aims: The present study was conducted with the aim of investigating the effectiveness of the training provided through the educational-therapeutic model of codependency injury based on the perception of lived experiences on the self-efficacy of teenagers in Khatam city.
Methods: The present research method was a semi-experimental pre test-post test type with a control group. The statistical population of the research included all teenagers of Khatam city in the academic year of 2021-2022. Among them, 30 people were selected as a purposive sampling and randomly assigned to two experimental and control groups. The experimental group received 12 sessions of educational-therapeutic model based on students' experiences, but the control group did not receive any intervention. In order to collect data, the Self-Efficacy Questionnaire for Children (Muris, 2003) was used. For data analysis, multivariate covariance analysis and SPSS-22 software were used.
Results: The results of the present study showed that after adjusting the pre-test scores between the groups, the post-test scores had a significant difference between the experimental and control groups (P< 0.001). Also, the results showed that education based on the educational model used had the greatest impact on academic self-efficacy, followed by social self-efficacy and the least impact on emotional self-efficacy (P< 0.001).
Conclusion: According to the findings of the present study, it is suggested that the officials of the education system consider the proposed model of this study in order to design and implement effective training for the growth and improvement of the self-efficacy of codependency teenagers.
