Adolescence is a pivotal stage for the onset of risk-taking behaviors, including antisocial behaviors. Most individuals exhibit aggressive or antisocial behaviors from time to time. Typically, growing children sometimes disobey adults, lie, fight, and scare other children. Antisocial behaviors are unacceptable because everyone has the right to live in an environment free from such behaviors (Saadu, 2024). However, when antisocial behaviors occur repeatedly, they have significant adverse effects on a child's functioning and development, such as emotional and cognitive problems (Bishop & Rutter, 2008; Raine, 2018). Among all adjustment problems, the theoretical foundations for the study of childhood and adolescent antisocial behaviors are the most abundant and historically rich (Costello & Angold, 2000). According to the DSM-5, antisocial personality disorder (ASPD) is characterized by a persistent pattern of antisocial and criminal behavior. However, it is not synonymous with criminality. Rather, individuals with ASPD demonstrate an inability to conform to social norms and exhibit inflexible and maladaptive interpersonal interactions. Individuals with ASPD typically have a history of conduct disorder (CD) from childhood. CD is characterized by a persistent and stable pattern of behavior in which the fundamental rights of others are violated or age-appropriate social norms or rules are broken (American Psychiatric Association, 2023). Antisocial behaviors, which often peak in adolescence, are costly to society and individuals and hinder the positive development of adolescents (Crocetti et al., 2016; Racz & McMahon, 2011; Crocetti et al., 2013). Antisocial behaviors, characterized by a persistent pattern of disregard for the rights and feelings of others, can have far-reaching consequences for individuals, communities, and schools. These behaviors not only cause direct harm to victims but can also disrupt the overall quality of life for individuals, communities, and schools. Victims of antisocial behaviors may experience fear, anxiety, and social isolation, which can lead to reluctance to attend school or leave their homes (Saadu, 2024). Individuals who chronically engage in antisocial behaviors are at increased risk for a range of negative life outcomes, including suicide, dropping out of school, unemployment, substance abuse, and incarceration (Caspi, Wright, Moffitt & Silva, 1998; Fergusson, Horwood & Ridder, 2005). Adolescents who engage in antisocial behaviors often face a multitude of psychosocial problems, as well as diminished educational and employment opportunities (Lyons et al., 2001; Odgers et al., 2008). Furthermore, their tendency to engage in risk-taking behaviors, often due to an underdeveloped understanding of the consequences of their actions, increases their likelihood of experiencing premature death (Boyer, 2006; Stoiber & Good, 1998). Reducing social harm is a critical objective for any nation's development programs, and achieving this goal requires a thorough understanding of the factors that contribute to these issues within society. Recognizing the vulnerability of adolescents and emphasizing that the emergence of antisocial behaviors is an inevitable aspect of adolescence can lead to more realistic approaches to identifying and preventing these behaviors. Consequently, parents, educators, and experts are constantly seeking ways to reduce these behaviors and prevent them from becoming entrenched patterns of behavior in adolescents (Crocetti et al., 2016).
Social psychologists and experts in social psychology have long been interested in prosocial and antisocial behaviors. They have identified a number of predictors of both prosocial and antisocial behaviors, and one of these predictors is moral identity (Hardy & Carlo, 2011). Moral identity can be defined as the extent to which moral ideals, values, traits, goals, roles, and behaviors are central to one's self-concept (Hardy & Carlo, 2011). Individuals with a stronger moral identity tend to engage in more prosocial behaviors (such as helping and volunteering), be more forgiving, show greater concern for others, adhere to moral commitments, and engage less in antisocial behaviors (Frimer & Walker, 2009; Hardy, 2006; Pratt, Hunsberger, Pancer & Alisat, 2003; Pratt, Arnold, & Lawford, 2009; Hardy, Bhattacharjee, Aquino & Reed, 2010; Colby & Damon, 1992; Barriga,Morrison, Liau & Gibbs, 2001). In line with this, Hardy, Bean & Olsen (2015) and Yildiz, Senel & Yildiran (2018) found in their studies that moral identity has a positive and significant relationship with prosocial behaviors and a negative and significant relationship with antisocial behaviors.
According to previous research, another variable associated with antisocial behaviors is effortful control. Effortful control is a temperament component defined as the ability to inhibit dominant responses, detect errors, and engage in planning (Rothbart & Bates, 2006). Individuals with lower levels of effortful control exhibit poorer social skills, lower social competence, higher levels of aggressive and delinquent behavior, more problems at home and school, and greater involvement with the police (Bakker, Ormel, Verhulst & Oldehinkel, 2011; Buckner, Mezzacappa & Beardslee, 2009; Cipriano & Stifter, 2010; King, Lengua, & Monahan, 2013; Kochanksa & Knaack, 2003; Lengua, 2002). Numerous other studies have also shown that low effortful control is a predictor of delinquency and recidivism, and this evidence exists across stages of development from childhood to adulthood, regardless of race, ethnicity, and gender (Heatherton & Baumeister, 1996; Rothbart, 2011; Sulik et al., 2010; DeLisi & Vaughn, 2015; Walters, 2014; Evans-Chase, 2014; Evans-Chase & Zhou, 2014; Gordon, Diehl, & Anderson, 2012; Roose et al., 2013; Stevenson & Goodman, 2001). In this line of research, Atherton, Lawson, Ferrer & Robins (2020) found a significant negative relationship between levels of effortful control and symptoms of hyperactivity, oppositional defiance, and conduct disorder problems in their study. This means that children who had lower levels of effortful control at age 10 showed more symptoms of hyperactivity, oppositional defiance, and conduct problems at the same age. This relationship was observed across all three components of effortful control (attentional control, activational control, and inhibitory control) and the two components of hyperactivity (inattention/impulsivity) and the two components of oppositional defiance (emotional dysregulation and defiance). Purwono et al.'s research also showed that effortful control is inversely related to antisocial behaviors (Purwono et al., 2019).
Another variable related to antisocial behaviors in the present study is the vengeful tendencies.Revenge is an important universal phenomenon in interpersonal relationships that can be described as an attempt to inflict suffering on those who have caused harm (Jackson, Choi & Gelfand, 2019; Elshout, Nelissen & Van Beest, 2015; Elster, 1990). One of the possible reasons for the vengeful tendencies is self-protection against the antisocial behaviors of others, and vengeful acts may be accompanied by impulsivity (Bushman & Anderson, 2001; Dodge, 1991). Fluck (2017) found that when he asked subjects to account for their bullying behavior,they identified revenge as the primary motivator for their actions. Numerous other studies have also shown the role of revenge in delinquent behaviors (Kivivuori, Savolainen & Aaltonen, 2016). In line with this, Dyduch-Hazar and Mrozinski (2021) found in their study that there is a correlation between the belief in the hedonic function of revenge and intergroup violence. Choe & Read (2019) also showed in their study that revenge has a positive and significant relationship with hostility, anger, physical aggression, and verbal aggression.
As previously mentioned, antisocial behaviors are predicted by the vengeful tendencies. Some research has shown that the vengeful tendencies can itself be predicted by moral identity and effortful control. People with high moral identity have a stronger moral motivation to avoid immoral behaviors such as revenge (Hardy, Krettenauer & Hunt, 2020). Acts of revenge can create significant personal risks through subsequent retaliation (Yoshimura, 2007). When personal aggression occurs, it may be followed by an irresistible urge to seek revenge (Lefranc, 2017). This compelling desire for revenge involves seeking compensation for the harm done in the form of retaliation (Acosta et al., 2020). Given that high levels of moral traits and moral identity are associated with prosocial behaviors, while they are negatively related to aggressive and antisocial behaviors, it can be said that high moral identity reduces vengeful tendencies and revenge-seeking behaviors (Hertz & Krettenauer, 2016; Hardy et al., 2014; Pozzoli, Gini & Thornberg, 2016; Teng, Nie, Zhu & Guo, 2020). The findings are also supported by research from Barclay & Whiteside and Aquino (2014). A high level of effortful control enables individuals to regulate their angry reactions when faced with a potentially provocative situation (such as revenge). Individuals with low effortful control, in contrast to those with high effortful control, are characterized as egocentric, impulsive, quick-tempered, and indifferent to the suffering of others (Gottfredson & Hirschi, 1990). They also have a lower tolerance for frustration and prefer immediate gratification. As a result, individuals with low effortful control have difficulty resisting their tendency to seek revenge (Restubog et al., 2015). In line with this, research by Balliet & Pronk (2013) and Burnette et al. (2014) shows that effortful control can effectively inhibit vengeful behaviors.
Current Study
The consequences of antisocial behaviors in adolescents have a detrimental impact not only on society but also on all those who are somehow connected to the individual. Annually, society bears immense costs for the maintenance, treatment, and rehabilitation of adolescents with antisocial behaviors. Correctional and educational programs for such adolescents focus on changing antisocial behaviors, neglecting the fact that these vulnerable youth are the product of the misconduct and malfunctions of certain social institutions such as families and schools (Foster, 2010). Antisocial behaviors exhibited by children and adolescents also vary in nature depending on the individual child or adolescent.These issues pose a significant obstacle to education and prevent educators from successfully imparting academic skills. Therefore, without understanding the factors influencing antisocial behaviors, efforts to modify such behaviors will have a limited scope and will not yield the desired effectiveness. Examining antisocial behaviors enables relevant authorities to gain insight into the formation of these deviant behaviors and subsequently seek appropriate methods to address them. Exploring the topic of antisocial behavior in adolescents can contribute to existing knowledge by uncovering the impact of these behaviors on their psychological development and social interactions. By conducting research and gathering information in this area, a better understanding of the factors influencing antisocial behaviors and their effect on society as a whole can be achieved. These findings can be utilized in the development of effective interventions and treatment strategies for those exhibiting such behaviors, as well as in informing programs and policies aimed at preventing antisocial behaviors. Additionally, such research can contribute to a broader understanding of the social and psychological factors that shape adolescent development, furthering our knowledge of human behavior and promoting adolescent well-being. Therefore, studies and research are necessary to gain a deeper understanding of deviant and maladaptive behaviors, uncover their origins, and pave the way for corrective and rehabilitative approaches through the identification and impact of the role of social institutions. Another application of the results of such research is the possibility of preventing the onset of delinquency and the downfall of talents, freeing families and the government from the losses of the present and future of the country.
This study aims to analyze the gaps in the research literature regarding the prediction of antisocial behaviors. In this field, the primary focus has been on relationships during adulthood, with limited studies on related predictions during adolescence. The absence of such studies underscores the significance of conducting this research. Many antisocial behaviors stem from a confused and disoriented identity (Wit-De Visser, Rijckmans, Vermunt & Van Dam, 2023). Investigating moral identity among adolescents holds importance due to their being at a crucial stage of development, during which their values and beliefs are shaped. By understanding the current state of moral identity among adolescents through research and data collection, educators can develop strategies and programs to promote positive moral development and prevent negative behaviors such as substance abuse, bullying, and violence. This information can also be used to inform policies and initiatives aimed at improving overall social and cultural values in the country. Additionally, given the emphasis on youthfulness, it is crucial for psychological research to delve into fundamental issues such as moral identity to serve as a beacon for passionate and hopeful adolescents.
The importance of examining the concept of effortful control is underscored by research indicating its role as a protective factor against engaging in risky behaviors such as substance use, aggression, and delinquency. Therefore, addressing effortful control plays a significant role in preventing or reducing various behavioral abnormalities, criminal behaviors, and delinquency (Clark, Donnellan, Robins & Conger, 2015). Effective interventions and strategies that enhance effortful control in adolescents can potentially reduce the occurrence of negative outcomes and promote positive outcomes such as academic success, social competence, and emotional well-being. Exploring effortful control can significantly contribute to existing knowledge by providing insights into how individuals regulate their emotions and behaviors and determining its contribution to antisocial behaviors. By reviewing theoretical frameworks and synthesizing research findings, a better understanding of this concept's impact on development, functioning, and enhanced psychological well-being can be achieved.
The necessity of examining the variable of revenge proneness is further emphasized by the paucity of research on this topic, particularly in the context of adolescence. Exploring the relationship between revenge proneness and antisocial behaviors can contribute to identifying more precise mechanisms involved in these processes. Revenge does not constitute a healthy or constructive approach to coping with conflicts or negative experiences. Instead, it often leads to heightened anger, hostility, aggression, risky behaviors, and social isolation. Additionally, revenge-seeking can exacerbate conflicts, inflict further harm on oneself and others, and result in legal consequences that have long-lasting effects on adolescents' lives (Chester & DeWall, 2016).
Ultimately, no study has investigated whether vengeful tendencies mediates the relationship between moral identity, effortful control, and antisocial behaviors. Moreover, a closer examination of empirical work on moral identity, effortful control, and vengeful tendencies in individuals with antisocial behaviors suggests that the relationships between these concepts are far more complex than these simplistic hypotheses imply. Therefore, this study was conducted to further examine the relationship between moral identity, effortful control, vengeful tendencies, and antisocial behaviors. In this study, vengeful tendencies is expected to mediate the relationship between moral identity and effortful control with antisocial behaviors (see Fig. 1). Consequently, the following hypotheses are proposed:
Hypothesis 1
Vengeful tendencies mediates the relationship between moral identity and antisocial behaviors.
Hypothesis 2
Vengeful tendencies mediates the relationship between effortful control and antisocial behaviors.
