In this paper we present the construct validity and reliability of 3D simulation program called My-School4Web, aimed to the detection of substance use, bullying and body image disturbances. In the same recreate different situations that have to do with this kind of behavior and, depending on the answers given by the participants, you get a risk profile. The sample consisted of 438 students of Secondary Education and students of the first university courses. Program factor structure shows the presence of four factors (accounting for 64.07% of the variance), which indicate the presence of three dimensions. Also acceptable reliability indexes are obtained. Results are discussed and the utility of this type of program
