The aim of this study was to test the efficacy of a 6-wk. educational program designed to improve physical self-concept, which was carried out in the classrooms of a university physical activity and sports faculty. The experimental group comprised 45 students (M age = 18.8 yr., SD = 1.5) and a control group (N = 41; M age = 21.7 yr., SD = 1.2). The Autokontzeptu Fisikoaren Itaunketa/Physical Self-concept Questionnaire (AFI) was administered pre- and post-intervention, with a statistically significant increase being observed in the post-test scores of the experimental group on the General physical self-concept scale, as well as on the Condition, Attractiveness, and Strength scales. No statistically significant changes were observed in the control group.
