Aim and Background: Drug use is a very serious concern for general health. There are various factors involved in drug use, family, social, psychological, and biological. The aim of the present study was to investigate the relationship between family factors and drug use among adolescents.
Methods and Materials: Statistical population of this study consists of all the students of Bushehr schools in the academic years 2011-2012 .Sample of this study consists of 1006 people (414 females and 592 males) were selected through cluster random sampling. Data were collected by Risk and Protective Factors of Drug use Questionnaire (Mohammadkhani 2004 Data were analyzed by stepwise multivariate Regression analysis.
Findings: The results of the multivariate Regression analysis showed that there is a significant and positive  relationship.between family factors (family conflicts, lack of monitoring children's behavior and positive attitude of parents to drug use) and drug use. The results of the Regression test for prediction of the use of drugs from family factors showed that family conflicts did not play a predicting role in explaining the use of drugs among adolescents and the lack of parents supervision on adolescents as well as parents 'attitude could predict codeine use and the parents' positive attitude to drug use has been able to explain the use of cannabis, grasses, crackers, glasses, X-pills, Ritalin, tramadol, and energizing drug. The use of energizing drugs was predictable by positive attitude of parents to drug use.
Conclusions: The findings of this study can be used in family-based interventions related to prevention and treatment of adolescents’ drug use, with emphasis on parenting surveillance and parental attitude to drug use.

Aim and Background: Adolescence is the period of transition from childhood to adulthood in which adolescents experience many changes, and their reactions to these changes are different. One of the maladaptive behaviors in this regard is aggression, which has long been the focus of many interventions. The present study aimed to investigate the effect of supportive psychotherapy on reducing physical aggression in male adolescents
Methods and Materials: In this study, a single case method with an A-B design was used. The statistical population included male adolescents aged 12-18 who were referred to the social emergency center with symptoms of chronic aggression during the first six months of 2020, of whom three were selected by purposive sampling. After three baseline sessions, the intervention sessions began, and a supportive psychotherapy package was administered for eight sessions of 45 minutes per week. Two follow-up sessions were held two weeks and one month after the intervention, and the results were evaluated. The data were collected by the Physical Aggression subscale of the Aggression Questionnaire (1).
Findings: A stable change index and recovery percentage were used to test the research hypothesis. Based on the overall recovery percentage of the three samples after treatment (42.77) and follow-up (48.02), it was concluded that supportive psychotherapy was effective in reducing physical aggression in adolescents. Conclusions: Supportive psychotherapy was effective in reducing aggression in male adolescents. This treatment controls aggressive behaviors by increasing self-confidence and awareness of the strengths and weaknesses.

Aim and Background: Many attempts have been made to determine the nature of crime based on psychological, sociological, and cultural variables. This study seeks to answer whether dark personality traits and dimensions of temperament and character affect criminal behaviors through self-control.
Methods and Materials: The research method is descriptive-correlational modeling of structural equation modeling. The statistical population of this study was all adolescents aged 13 to 17 years in Khorramabad city in 2023. The sample consisted of 350 adolescents who were selected by cluster sampling method and responded to the Dark Personality Questionnaire (Paulus & Jones, 2011), the Temperament and Character Inventory of Adan et al. (2009), the Self-Control Questionnaire of Tangney et al. (2004), and Adapted Self-Report Delinquency Scale Pechorro and et al (2019). Using AMOS 24 and SPSS 26 software, structural equation modeling was used to evaluate the proposed model.
Findings: The correlation coefficient results showed a positive and significant relationship between the dark personality triad and the behaviors of juvenile offenders (P<0.001). The results also showed that there is a positive and significant relationship between novelty and harm avoidance with criminal behaviors (P<0.001) and there is a negative and significant relationship between the rewards of dependence, perseverance, self-direction, cooperation, and self-transcendence with criminal behaviors (P<0.001). The results of structural equation modeling showed that dark personality traits and temperament and character dimensions explain 30% of the variance of self-control. Finally, 43% of the variance in criminal behaviors is explained by dark personality traits, temperament and character dimensions, and self-control.
Conclusions: According to the results, it can be concluded that dark personality traits and dimensions of temperament and character have an indirect effect on the behaviors of juvenile offenders through weak self-control skills.  Therefore, it is suggested that social harm prevention programs focus on self-control and self-control skills
