Background: Aggressive behaviors are the most critical and common challenges shown by children with autism spectrum disorders (ASD) through their life. Children- scale for hostility and aggression: reactive and proactive (C-SHARP) is a comprehensive instrument for measuring aggressive behaviors. No instruments have been developed for measuring aggression in children with ASD or other developmental disabilities in the Persian language; therefore, this study aimed to assess the reliability, validity and responsiveness to change of Persian version of C-SHARP in children with ASD.Methods: This is a psychometric study with three phases including translation process, assessment of the validity and reliability, and responsiveness to change. World health organization (WHO) guidelines for translation and adaptation process were used to translate the C-SHARP. To evaluate the psychometric properties of the instrument, we performed across-sectional study on 162 children with ASD and dimensionality and convergent validity, internal consistency, and composite reliability were used. In order to measure responsiveness, we performed a comparative study in the form of a free-gluten dietary intervention, and gamma correlation coefficient was used to correlate change the scores with GRS.Results: Cronbach’s alpha coefficients were reported greater than 0.85 for all subscales and the composite reliability coefficient for C-SHARP was 0.94. Root mean square error of approximation (RMSEA) was 0.052 which confirmed robust construct of C-SHARP Persian version. Average variance extracted (AVE) for total C-SHARP was >0.50. Gamma correlation coefficient was 0.77, indicating excellent responsiveness to change of the instrument.Conclusion: The current study approved the reliability, validity, and responsiveness to change of the Persian C-SHARP in children with ASDs. Persian C-SHARP can be used in clinical and research settings to assess aggression.

Introduction: Given the importance of aggression in adolescents and the effects of parenting practices, the present study was conducted to investigate the effects of parenting skills intervention on adolescent aggression in Abadeh Tashk town, Fars province, in 2018. Methods: This randomized clinical trial was carried out on 200 adolescents and their parents in Abadeh Tashk in 2018. The sampling was done through the cluster sampling method and the subjects were randomly divided into the experimental and control groups (100 in each group). The study outcomes were aggression and parenting styles measured by the control and education groups before and two months after the intervention. The data were analyzed using the SPSS20 software as well as the statistical tests such as paired t-test, independent t-test and chi-square test. Results: The results showed that there was no significant difference between the experimental and control groups in terms of physical aggression (P = 0.98), verbal aggression (P = 0.62), anger (P = 0.40), hostility (P= 0.15), and the total aggression score (P= 0.38) before the intervention. However, after the intervention, a significant difference was found between the two groups in terms of physical aggression, verbal aggression, anger, hostility, and overall aggression score (P <0.05). Conclusion: The results of this study showed that parenting style intervention was effective in reducing physical and verbal aggression, anger, hostility, and overall aggression in students. It is suggested that long term interventions should be conducted aiming at parental control over the problems of students since childhood.
