Objective: This study aimed to develop a healthy body image package for adolescents aged 12 to 15 years with body image dissatisfaction. Methods and Materials: The research method was a theory-driven deductive thematic analysis. In the qualitative content determination phase, the content, structure, and final form of the healthy body image package were developed using a five-step method based on theory-driven thematic analysis in line with Attride-Stirling's (2001) thematic network analysis. The statistical population included scientific texts related to a healthy body image and experts in the field of adolescent psychotherapy. Purposeful sampling was employed based on the content relevance of 30 scientific texts to strategies for promoting a healthy body image in adolescents until theoretical saturation was reached. Additionally, 6 expert psychotherapists with more than 10 years of experience in adolescent psychotherapy participated. Data were analyzed using theory-driven thematic analysis. Findings: The findings indicated that the content of the healthy body image package included four main concepts: perceptual strategies training, emotional strategies training, cognitive strategies training, and behavioral strategies training. The content validity of the educational package was equal to 1. Conclusion: According to the results of the present study, it is suggested that this educational package be taught to managers, teachers, and counselors to reduce body image dissatisfaction in adolescents.
