Adolescence begins with physical, psychological, social, and spiritual changes and encompasses the age range from 10 to 19 years (
1). In addition to the physical and emotional upheavals, this transition also changes adolescents' value systems and social attitudes (
2). The developmental process and brain changes during this time make adolescent girls vulnerable to emotional reactivity and poor decision-making, leading to susceptibility to risky behaviors such as delinquency (
3).
Deviant behaviors such as tobacco use, violence, aggression, addiction, drug dealing, school vandalism, theft, and murder are recognized as delinquent acts (
4). Juvenile delinquency is associated with a variety of negative consequences, such as poor academic performance (
5,
6), social adjustment (
6), and substance abuse (
7). The process of detachment from the family can also be hindered by institutional influences, leading to frustrations that cause adolescents to engage in behaviors that demonstrate independence, such as delinquent behaviors, in an attempt to express maturity (
8). To explain this temporary increase in delinquency, Moffitt (
9) hypothesizes in her developmental taxonomy that delinquency confined to adolescence is motivated by the developmental need for autonomy and independence arising from role ambiguity caused by a discrepancy between biological and social maturation (i.e., the maturation gap). Deviance could thus become a normative part of the search for gender identity (
10). Gender identity is a crucial concept that can have a significant impact on the physical and psychological condition and quality of life of adolescent girls, whether or not they are delinquent (
11). Psychologists define gender identity as the image and feeling individuals have of their femininity or masculinity and the expectations they have of themselves as different genders (
12). Socio-cultural conditions, upbringing and instilled values and teachings influence individuals' understanding and beliefs about their gender identity. Therefore, gender identity is a composite identity directly or indirectly influenced by various personal and social conditions, factors, and roles (
13). Gender identity disorders can lead to deviant and antisocial behaviors, including criminality (
14). Researchers also believe that the occurrence of gender identity disorders may be associated with delinquency. For example, delinquency and personal identity are related during adolescence. Experimentation with delinquency hampers identity formation by increasing rumination and decreasing commitment (
15). Delinquency was found to be associated with self-esteem (
16). Focusing on promoting positive self-esteem may also reduce the risk of male adolescents struggling with the harmful consequences of delinquency (
17). Traditionally; self-esteem has been considered an important correlate of psychosocial competence and adjustment (
18). Several studies have shown a high correlation between low self-esteem dimensions and deviant and delinquent behavior (
19). For example, Mier and Ladny's (
16) meta-analysis of 42 studies showed that adolescents with low self-esteem commit criminal and delinquent acts. High self-esteem had a significant effect on preventing delinquency (
16). Another study found a significant positive relationship between drug use and social self-esteem (
20). Self-esteem is also a factor directly related to lower delinquency rates (
21,
22). From an ecological perspective, the lack of a healthy family life is considered one of the most influential factors that can lead to delinquency in adolescents through lowered self-esteem and gender identity disorders (
23). Ode et al. (
24) found that the rupture of family ties leads to adolescent delinquent behavior. Parsons emphasizes the importance of positive family functions such as emotional support, love, and a safe environment for children to prevent deviant behavior (
25).
Positive parental relationships can help buffer this stress and have been associated with lower-risk behaviours, including delinquency (
26,
27). Parental efficacy significantly affected delinquency, even after controlling for self-control (
28,
29). In this context, Kroese et al. (
30), who compared the family atmosphere of delinquent and nondelinquent youth, showed that the family relationships of delinquent youth were not as conventional as those of nondelinquent youth. That is, there was a lack of understanding between parents and delinquent youth, and there was less respect and solidarity among family members, leading to a decline in self-esteem, especially among children. In addition, the protective effect of parental warmth on delinquency has been demonstrated (
31).
Studies by Bezin et al. (
23) and Rezaei-Dehaghani et al. (as cited by Aggarwal et al.) (
32) have found that those who grow up in healthy families have higher self-esteem and better coping skills, leading them to be less prone to delinquency. However, girls who experience humiliation or failure, have cold and inferior relationships with their parents and face gender discrimination may engage in delinquent behavior to boost their self-esteem or compensate for feelings of inadequacy resulting from experiencing gender inequalities in the family.
As you can see, the issue of crime and deviance among youth has always been an important topic for many scholars. A review of crime rates worldwide, including Iran, shows that crime is one of the critical issues in our society. In surveys conducted in most countries, crime rates and delinquency, especially between the ages of 12 and 25, continue to rise. The quantitative trend of juvenile delinquency in Iran increased from 7,644 cases in 1995 to 25,089 cases in 2000 (
33).
Considering the importance of the issue of delinquency among girls as future mothers and creators of the next generation, which can be a serious obstacle to the development of individual talents and the development and progress of a country, and considering that most studies on this issue have been quantitative, the main difference of this research is its qualitative exploration based on the lived experiences of delinquent adolescent girls.
