Introduction Importance of children's mental health issues at personality evolution and the impact of dysfunctional behavioral responses during this period make it clear that there is a need to interpretation. Hence, in this field, assessment and screening is a one of the fundamental solution in order to identifying the problems. The present study was designed and conducted to assess the behavioral responses. Methods :This descriptive-analytic study was conducted with random and available sampling of 240 students (both girl and son) in the range of 9-16 years old (from Tehran preps and secondary schools-2015) using the scale of dysfunctional behavior, feeling and thoughts. The ANOVA, Kruskal-Wallis, Chi-square, Fisher and U Mann – Whitney tests, were used for analysis. Findings Results have shown that intensity of dysfunctional behavioral, emotional and intellectual responses were observed in 61.6% of the samples. The frequency and intensity were higher in girls than boys. This situation was true about 73.7% of girls and 50% boys. Conclusion: As for involving the large number of students with dysfunctional behavioral disorders, screening seemed to be necessary for identifying these individuals and referrals them to consulting centers because of diagnosis disorder, and interventions – educational treatment.
