Abstract
Introduction: Given the increasing risk-taking behaviors among adolescents and young people, the aim of the present study is to investigate structural relationship model of risky behaviors in adolescents, specifically investigating the roles of family cohesion and impulsivity, with rumination serving as a mediating variable.
Methods: The statistical population of the study consisted of all eighth-grade male adolescents in Mashhad in the academic year 1403-1404, which was 2997 people. From the statistical population, considering the probability of dropout, 300 people were considered as a sample and were selected using the available sampling method and responded to questionnaires on high-risk behaviors, family cohesion, and impulsivity, Rumination. Inferential statistics indicators such as path analysis were used to analyze the research data. The data were analyzed using SPSS 22 and PLS 3 software.
Results: The results showed that there is a negative and significant relationship between family cohesion and risky behavior (r= -0.36) (p< 0.01). There is also a positive and significant relationship between impulsivity and risky behavior (r= 0.45). Also, rumination was significantly related to risky behaviors (r= 0.33). The indirect effect of family cohesion on risky behavior through the mediation of rumination is significant (p< 0.05), and the indirect effect of impulsivity on risky behavior through the mediation of rumination is significant (p< 0.01). Rumination was also significantly related to risky behaviors. Also, according to the fitted model, the indirect relationship between impulsivity and high-risk behaviors in teenagers with the mediation of mental rumination is significant (SRMR= 0.09, NFI= 0.05, df/χ2= 5.98).
Conclusion: Based on the findings, the assumed research model was confirmed by emphasizing the role of family cohesion and impulsivity and with the mediation of mental rumination. This finding shows that the combination of low family cohesion, high mental rumination, and extreme impulsivity are among the factors behind the occurrence of high-risk behaviors in teenagers.
