Abstract:
We assessed changes in the body image of Spanish adolescents who participated in a programme aimed at preventing disordered eating, with a 30-month follow-up. 254 girls and 189 boys aged 12-14 were assigned to a control group (n=201) or one of two possible experimental conditions: media literacy programme (ML, n=143) and media literacy plus nutrition awareness programme (ML+NUT, n=99). Body image was assessed with the Body Image Questionnaire (Qüestionari d'Imatge Corporal; QÜIC). Pre-test, post-test, 7- and 30-month follow-up measurements were taken. Linear model analyses were carried out with a 2×3×3 ANOVA (sex×group×phase), adjusted by the baseline level. At 30-month follow-up, ML and ML+NUT participants showed fewer body problems and more body satisfaction than the control group. There is a need for prevention programmes addressing eating and body image disturbances that involve both boys and girls.
