Abstract Introduction: Antisocial behaviors—characterized by actions that violate social norms and laws, such as aggression, violence, and property damage—can have severe consequences for adolescents, including academic struggles, social difficulties, and legal repercussions. These behaviors also harm interpersonal relationships with family and peers. This study examined the mediating role of vengeful tendencies in the relationship between effortful control and antisocial behavior among adolescents in Shiraz, Iran.  Method: The study population included all high school students in Shiraz during the 2022-2023 academic year. A sample of 567 students was selected using multi-stage cluster random sampling. Participants completed validated measures of Effortful Control (Ellis & Rothbart, 2001), Vengeful Tendencies (Flores-Camacho et al., 2022), and Antisocial Behavior (Burt & Donnellan, 2009). Path analysis was conducted using SPSS-24 and AMOS-24 to test the proposed model.  Results: The model demonstrated good fit. Findings revealed significant direct effects of effortful control on vengeful tendencies (p = 0.000, β = -0.51), effortful control on antisocial behavior (p = 0.000, β = -0.11), and vengeful tendencies on antisocial behavior (p = 0.000, β = 0.13). Additionally, vengeful tendencies mediated the relationship between effortful control and antisocial behavior (p = 0.000, β = -0.29) at the 0.01 level.  Conclusion: The results suggest that improving effortful control may reduce vengeful tendencies and, consequently, antisocial behaviors in adolescents. 

Abstract Introduction: Present study aimed to mediate the role of Self-regulation in the relationship between Sports self-efficacy and Self-concept with weight loss behaviors of students. Method: The current research is a descriptive survey of the correlation based on structural equation modeling. The study’s statistical population included all female and male first-high school students in Eqlid (Fars province) in the academic year 2022-2023. The sample size of 250 students was selected by multi-stage cluster random sampling. After examining the questions related to the subject’s height and weight, they were grouped as overweight and obese with a body mass index of 25 or higher. Data were collected using the standard Mendaglio and Pirist self-concept (1995), Kerel and colleagues (2007) sports self-efficacy, Miller and Brown (1999) self-regulation, and weight loss behavior questionnaire by Mazloumi Mahmoudabad and colleagues (2017). Data analysis was performed by Structural Equation Modeling and with PLS 8.8 software. Results: The results showed that sports self-efficacy and self-concept a had direct and significant effect on weight loss behaviors. Also, the results showed that self-regulation has a mediating role in the relationship between sports self-efficacy and self-concept with behaviors related to weight loss behaviors. Conclusion: By increasing sports self-efficacy, self-concept, and self-regulation, weight loss Behaviors will also increase. Therefore, it is better in environments where therapists, pay more attention to sports self-efficacy, self-concept, and self-regulation in obese and overweight teenagers.
