Criminality, Substance abuse and Problematic Family Relations in Adolescence

During adolescence there is an increasing possibility of becoming a perpetrator of violence or being involved in atrisk behaviors, such as drugs use and unlawful acts. Such behavioral diffi culties burden families, schools, communities, and society at large.

Introduction
During adolescence there is an increasing possibility of becoming a perpetrator of violence or being involved in atrisk behaviors, such as drugs use and unlawful acts. Such behavioral diffi culties burden families, schools, communities, and society at large. Substance abuse during adolescence is often associated with delinquency and aggressive conduct, which are common among adolescents who experience family confl ict or parental neglect.
Delinquency and substance use could become habitual modes of conduct and communication for adolescents. The importance of the family system and parenting in this regard has been emphasized by several studies carried out in Europe, the United States, South America, Africa and Asia. They all conclude individually on the large impact of parental support and parenting style, parental drinking and incarceration on the youth's illicit and antisocial behavior and on substance use [1][2][3].

Data on adolescents with risky behavior in consideration of their family structures
To begin, an overview about various data collected on adolescents' risky behavior will be given. This will stress the signifi cance of parents' presence and infl uence or lack thereof.
Data from the Youth Risk Behavior Surveillance [4], report that 11.1% of youths has been in a physical fi ght in school, and 5.6% has carried a weapon at least once in the past month and that one of the signifi cant risk factors in their behaviors is family disruption. Analysing adolescents' focus-group data regarding their perceptions of violence and their coping strategies in managing confl ict, emerged that they were aggressive mostly to protect family. Participants also used terms of endearment and possession to identify family membership, for instance, the term "my princess" referring to a cousin. They described their communities and lives as lacking in supports and safety, affi rming that the use of violence is a strategy to survive. The adults in their lives were perceived as unable to protect and https://www.peertechz.com/journals/journal-of-addiction-medicine-and-therapeutic-science Citation: Saladino  help them in avoiding fi ghts. Most participants affi rmed that their parents were absent all the time and that they did not provide any protection against others' violence. For some of the participants in the study, their mothers were perceived as protective against neighborhood violence. Additionally, this perception of the family involved an excess of responsibility and a lack of confi dence, which affected the participants' interpersonal anger management skills.
Data from the National Longitudinal Study of Adolescent Health [5], confi rm these results, reporting low-income family background as one of the primary predictor variables of early adolescent substance use. Participants who had unemployment parents and relationships with people involved in illegal acts, were more likely to perceive lower cohesion and safety in their social context and to experiment binge drinking and smoking marijuana.
On the other hand, participants who perceived their parents as more conscientious and present were less likely to engage in substance use and delinquent acts. Moreover, the use of drugs is not affected by social and individual risk factors whether the family is intact. Tucker and colleagues (Ibidem) examined the infl uence of family risk factors in the use of substances, assessing the following variables: low parental control, closeness to mother, availability of drugs at home, differentiating between alcohol and illegal drugs.
Regarding marijuana initiation, an intact family is a protective factor that is not associated to personal demographics, as gender, age and ethnicity; while binge drinking is associated with behavioral and family risk factors, such as the use of marijuana, delinquent behavior, low parental supervision, permissive or absent parents, and having alcohol readily available in the home. Moreover, these results show a difference between risk factors and type of substance: marijuana is more related to peers and linked to illicit activities, while binge drinking relates to the family system (opportunity to drink at home or parents who drink).
Additionally, adolescents who experienced these risk factors foresee few opportunities for themselves and have less hope for the future. Consequently, they may be at higher risk in drug selling and related activities. Along the same lines, the Northeast Communities Against Substance Abuse conducted a survey, involving rural and suburban communities and associating alcohol consumption with parental drinking.
In fact, parental drinking seems to be associated with increased odds to become an alcohol experimenter, occasional polysubstance user, or frequent polysubstance user. At the same time, parental disapproval of substance use is associated with decreased odds to become a frequent polysubstance user compared to other users.
According to Canadian Institutes of Health Research and the Heart and Stroke Foundation of Canada the same results are valid for the use of marijuana [6]. Marijuana remains the most commonly used illicit drug among adolescents, frequently related to addiction, to the use of other illicit drugs (OID) and to delinquent and aggressive behaviors. As in alcohol users, frequent marijuana use is negatively related to parental support, as shown by a comparison between frequent lifetime marijuana users to never or less frequent lifetime marijuana users. Therefore, good relationships with parents may reduce the risk to develop an addiction or to use OID during adulthood.
The family system infl uences adolescents' risky behavior.
Regarding to violence it has been shown that it is considered a form of communication, often connected to the perceived unreliability of adults. For substance abuse, there seems to be evidence that, although experiments with binge drinking and marijuana depend on different circumstances, an intact family system functions as a protective factor. Accordingly, it will be shown in the next paragraph how certain parenting styles affects teens' tendencies towards criminal behavior and substance abuse.

Infl uence of different parenting styles on adolescent development
According to the literature, each family is a dynamic system composed by a specifi c parenting style. The construct of parenting style, initially described by Baumrind in 1991 [7], is characterized in two dimensions: affection or responsiveness and control or demandingness, giving rise to four distinct categories: authoritarian style, authoritative style, indulgent style and negligent style [8].
Responsive parents are affective, empathic, and close. They pay attention to their children's lives, communicating affection and recognizing their achievement. Conversely, demandingness refers to control, severe education and enforcing to respect strict rules of behavior.
Based on this theory, parents with an authoritarian style report a low level of affection and a high level of control; authoritative style is characterized by a high level of both affection and control; indulgent style involves high affection but low control, and negligent style is characterized by low level of both affection and control.
Adolescents whose parents are authoritative are less likely to become heavy drinkers. They show more resilience, selfesteem and a better psychological adjustment. Additionally, authoritative parenting is negatively related to alcohol use even when adolescents have friends who drink [9].
Negligent parental style impairs self-regulation skills of youths, thus teenagers may develop problems of adaptation and functionality related to behavioral problems, or social competence [10][11][12][13][14]. A research on German students showed the relationship between negative parenting and aggressive conducts [15]; another research on Turkish adolescents emphasized the importance of perceived parenting on aggression and self-esteem [16,17].
In contrast with these fi ndings, some studies consider authoritarian parental style as a risk and indulgent style as a protective factor [18,19] and show that adolescents who have authoritarian and authoritative parents appear more hostile than others, and that mother's deprivation, physical Citation: Saladino  coercion, and mother's verbal coercion are the most signifi cant predictors of hostility [19][20][21][22]. Also, data obtained from class analysis showed an inverse association between negligent parenting styles and alcohol users/binge drinkers, tobacco, marijuana and synthetic drugs [23]. However, the majority of fi ndings identify authoritative style as a protective factor. Other studies focused on the differences between mother and father [24], found that mother is often more indulgent than father, who is more negligent.
Negligent father' style may involve externalization problems in teens more than the indulgent mother' style. Studying the association between fathers' and mothers' parenting style and externalizing behaviors, Groh, et al. [25], found that father's participation has a positive impact on the acquisition of empathy and social skills, factors related to lower rates of risky behaviors. The relevance of father's parental style was confi rmed by a longitudinal study conducted by the Centre for Research into Parenting and Children, Oxford, United Kingdom. As noted in this study, father's involvement in the adolescent life plays a protective role in well-being of the adolescent. These fi ndings are also associated with positive parent-adolescent relationship, and with a low level of aggressiveness [26].
In this line, the Baltimore Prevention Project [27], collected data from high school students and examined associations between incarcerated fathers (FEI) and substance use during adolescence for the US population; 13% of the sample had fathers in jail and this is associated with an increasing use of marijuana and OID, and higher levels of delinquency. Other outcomes suggested the positive correlation between father imprisonment and alcohol and marijuana use; 51.3% of males and 39.3% of females with FEI reported using marijuana, compared to 37.7% and 28.3% of males and females, respectively, without FEI. Father's imprisonment is not the only factor, but it is related to other factors of the family system, such as parental separation, poor parenting, history of physical abuse, maltreatment and parents' neglect, which are also associated with criminal involvement. Violence, abuses, and abandonment are more related with criminality during adolescence and adulthood than parental substance use.
The mother also plays an important role in adolescent life: National Longitudinal Study of Adolescent Health indeed reported that mother' binge drinking and demandingness could be a predictor of substance use in adolescence [28].
Finally, the most favorable situation for adolescents is to have support and involvement in their lives from both parents. Moreover, authoritative parenting style is associated with less confl ict within the family and subsequent developmental adjustment for adolescents [12]. In late adolescence parentchild relationship gradually become less hierarchical and more horizontal, and teens need more emotional support from their parents. Hence, in this phase maternal and paternal support should focus on emotional regulation [29,30]. Based on the review of the literature, therefore, the important central aspect is the balance between affection and control and the role of father and mother in parenting: the father as the educator in social and normative skills and mother as a caregiver [31].
Additionally, attachment and sense of belonging to the family or surrogates like school, peers, and religious communities, mediate the use of violence. These aspects guarantee informal control during the transition to adulthood and reduce likelihood of future involvement in the legal system. Secure attachment and close relationship with parents decrease the rate of violence [32] and promote relational and social skills [33]. Adolescents with secure attachment show more confi dence and better emotional regulation skills than adolescents with avoidant attachment, who have more diffi culty in interpersonal relationships [34].
The role played by the father is essential for attachment and also as a predictor of adolescent' aggressive conducts.
The scientifi c literature highlights that family structure also infl uences behavior. Children who lived in mono-parental and dysfunctional family are more likely to fall into risky behavior during adolescence [35] than children who lived in an intact family. Data collected from 372 single-mother families showed that maternal responsiveness positively infl uences adolescent development as compared to "broken" homes and "defi ciency" of single-mother families [36].
Similar results are common in adolescents who have good family' communication and disclosure [37]. This confi dence facilitates emotional managing, problem-solving and coping skills, decreasing violent and risky acts [38].

Contrariwise poor communication involves an emotional
gap, which may develop in risky behavior and parental drug talk styles in early adolescent may increase the use of substance in teens [39].
Parenting and children-parent relationship is important also in order to promote the development of self-control, aspect often involved in criminal and risky conducts.

Crime and self-control: the importance of family education
According to the well know General Theory of Crime by Gottfredson and Hirschi [40], criminal conduct derives from two elements: self-control and opportunity. The authors affi rm that a reduced ability to self-control can leads to an increased probability of committing a crime when the opportunity in engaging the behavior is present [41].
The level of self-control in children is strongly infl uenced by the parenting style, and becomes stable during the development: their children to resist to easy gratifi cation, supporting them, increase the possibility of their success in social institutions and interpersonal relationshipswhich require delay in gratifi cation, tolerance of frustration and the acceptance of compromises [43]. Indeed, children who develop a good self-control are more likely to implement prosocial behaviors in adolescence and adulthood, avoiding criminal conduct.
Based on the general theory of crime and on the main studies on parenting styles, Li, et al. [44], focused their study on three categories of parenting: positive educational practices, negative educational practices, and parent-child relationships.
Their study described positive parenting as a balance between control and warmth, such as monitoring, supervision and support; negative parenting characterized by overprotection, hostility and coercive punishment, and parentchild relationships as children's bonds with their parents.
These parenting styles infl uence the development of selfcontrol and the relational skills of youths. For instance, positive parenting promotes close parent-child relationship and help parents in teaching self-control to their children [45,46]. In the same line, youth with good self-control are more likely in engaging socially desirable behavior and in listening their parents.
These results suggest the infl uence that parenting style has in youths' self-control and vice versa, underling the protective role of both, in behavioral problems and risky conducts of adolescents.

Conclusion
Taken together, these fi ndings suggest that parental support, psychological control, and parental monitoring, attachment and communication are mediators in teen's risky behaviors, emphasizing the importance to promote parental skills in order to decrease negligent parenting.
It would be simplistic, however, to continue considering the relationship between parent and adolescent as a oneway street. Based on the most recent researches, it would be closer to reality the description of this relationship as coconstructed by parents and adolescents, as a circular system. It will therefore be necessary for future studies to collect data that considers the interplay of parents and adolescents in order to gain a better understanding of the causes and motivations behind adolescents' risky behavior.
