Bullying, drug use, and eating disorders: An assessment by using a 3D simulation instrument in educational settings

My-School4web consists of 12 three-dimensional scenes that recreate situations in the life of adolescents in which drug use, bullying and body image problems take place. To investigate the validity of My-School4web's scenes, the answers obtained using My-School4web were compared with three questionnaires. 438 students from Spain participated. Results show there are statistically significant associations (p<.05) between the responses obtained from the 12 scenes of My-School4web and those obtained from the questionnaires. Considering the effect size of the associations, 10 out of 12 scenes showed large to medium strength of the associations.
