Resumen:
The current study used clinical and statistical significance tests to investigate the effects of two forms (didactic or interactive) of a universal prevention program on attitudes about shape and weight, eating behaviors, the influence of body aesthetic models, and self-esteem. Three schools were randomly assigned to one, interactive, didactic, or a control condition. Children (61 girls and 59 boys, age 9-11 years) were evaluated at preintervention, postintervention, and at 6-month follow-up. Programs comprised eight, 90-min sessions. Statistical and clinical significance testing showed more changes with the interactive program versus the didactic intervention and control group. The findings support the use of interactive programs that emphasize identified risk factors and construction of identity based on positive qualities unrelated to physical appearance.
