The sample includes 642 students who were selected by random sampling. Explanatory Factor analysis with varimax rotation indicated six-factor structure as the simplest factorial solution which consisted with theoretical background. In addition, all the subscale had good reliability which ranged between 0.63 (for disruptive behavior) to 0.85 (for academic achievement deficit, self-regulation, attention deficit/hyperactivity disorder, and self-harm).
