چکیده انگلیسی

Prospective longitudinal birth cohort data was used to examine the association between peer aggression at 14 years and mental health and substance use at 17 years. A sample of 1590 participants from the Western Australian Pregnancy Cohort (Raine) study were divided into mutually exclusive categories (victims, perpetrators, victim-perpetrators and uninvolved). Involvement in any type of peer aggression as a victim (10.1%), perpetrator (21.4%), or a victim-perpetrator (8.7%) was reported by 40.2% of participants. After adjusting for confounding factors, those who were a victim of peer aggression had increased odds of later depression and internalising symptoms whilst perpetrators of peer aggression were found to be at increased risk of depression and harmful alcohol use. Victim-perpetrators of peer aggression were more likely to have externalising behaviours at 17 years. These results show an independent temporal relationship between peer aggression and later mental health and substance use problems in adolescence.

There are three main groups of participants in peer aggression; the victim, the perpetrator and a third group who are both the victim and the perpetrator (victim-perpetrator) (Austin and Joseph, 1996, Haynie et al., 2001 and Veenstra et al., 2005). The estimated prevalence of peer aggression (victim or perpetrator) ranges from 5% to 35% with lower prevalence (3%–13%) for those in the victim-perpetrator group (Copeland et al., 2013, Craig et al., 2009, Cross et al., 2009, Due et al., 2008, Jansen et al., 2012, Solberg and Olweus, 2003 and Sourander et al., 2007b). The variation in prevalence has been linked to methodological differences in definition and measurement (Griffin and Gross, 2004 and Shaw et al., 2013) with recent studies now incorporating cyber-aggression. Irrespective of this, it is clear that a large number of children and adolescents are involved in peer aggression. Victims of peer aggression are more likely to have fewer close friends, and are at increased risk of mental health problems, particularly internalising symptoms which are characterised by an over control of emotion expressed through behaviours such as excessive worrying and social withdrawal (Achenbach and Edelbrock, 1978, Arseneault et al., 2006, Boulton and Underwood, 1992, Nansel et al., 2001 and Zeman et al., 2006). It has been further demonstrated that victims of peer aggression are likely to display sub-assertive behaviour which may increase their likelihood of becoming victims of peer aggression, as perpetrators of peer aggression perceive them as easy targets that are less likely to retaliate (Fekkes, Pijpers, Fredriks, Vogels, & Verloove-Vanhorick, 2006). Longitudinal studies have consistently found strong links between victims of peer aggression as a child or adolescent and later mental health problems including depression, anxiety, suicide ideation and suicide attempts (Copeland et al., 2013, Heikkilä et al., 2013, Hemphill et al., 2011, Klomek et al., 2008, Sourander et al., 2007b and Ybrandt and Armelius, 2010). The association between being a victim of peer aggression and later substance abuse problems is less clear with some studies reporting that victims of peer aggression are less likely to drink alcohol later in life (Nansel et al., 2001) whereas others suggest that being a victim of peer aggression is associated with an increased risk of later harmful alcohol use (Goebert et al., 2011 and Tharp-Taylor et al., 2009). Similarly some studies have shown an association between being a victim of peer aggression and later illicit drug and tobacco use (Goebert et al., 2011, Niemela et al., 2011 and Tharp-Taylor et al., 2009), whereas others have found no association at all (Copeland et al., 2013, Hemphill et al., 2011 and Sourander et al., 2007b). Perpetrators of peer aggression have been consistently found to be at increased risk of mental health problems particularly externalising behaviours which are characterised by an under control of emotions and are displayed through acts such as impulsivity, defiance, swearing and aggression towards others (Achenbach and Edelbrock, 1978, Kim et al., 2006, Sourander et al., 2010, Van der Wal et al., 2003 and Veenstra et al., 2005). Most longitudinal studies show perpetrators of peer aggression in early adolescence to be at an increased risk of later alcohol dependence and other substance abuse problems as well as increased risk of later criminal and violent behaviour (Farrington and Ttofi, 2011, Hemphill et al., 2011, Niemela et al., 2011, Sourander et al., 2007a and Sourander et al., 2007b). Some studies suggest that being a perpetrator of peer aggression in childhood or adolescence increases the risk of later depression, however this is seen predominately in males (Kaltiala-Heino et al., 2010 and Klomek et al., 2008). Furthermore longitudinal evidence suggests that perpetrators of peer aggression are more likely at risk of anti-social personality disorder (Copeland et al., 2013 and Sourander et al., 2007b). Compared to studies of victims and perpetrators of peer aggression, there is less research examining the concurrent and later mental health problems of victim-perpetrators of peer aggression. This group are more likely to display externalising behaviours similar to perpetrators of peer aggression, but also have internalising behaviours similar to victims (Ivarsson, Broberg, Arvidsson, & Gillberg, 2005). Victim-perpetrators of peer aggression have the highest risk of later psychiatric problems (Copeland et al., 2013; Kumpulainen and Räsänen, 2000 and Sourander et al., 2007b) and the poorest psychosocial functioning out of the three groups (Haynie et al., 2001 and Veenstra et al., 2005). They have an increased risk of wide ranging adverse outcomes including anxiety, depression, suicidal ideation, substance use disorders and criminal behaviour (Copeland et al., 2013, Kim et al., 2005, Klomek et al., 2008, Sourander et al., 2007a, Sourander et al., 2007b and Winsper et al., 2012). General strain theory is a framework that explains the underlying process in which peer aggression affects mental health and substance use (Agnew, 1992 and Agnew, 2001). This argues that those who are exposed to strain or strenuous events (i.e. peer aggression) often develop negative emotions as a result. These negative emotions such as depression, anxiety, and anger can then lead to the individual trying to escape the strain through acts such as substance use, self-harm or suicide (Hay, Meldrum, & Mann, 2010). Although this provides a rationale for why victims or victim-perpetrators of peer aggression develop mental health and substance use problems it does not explain why perpetrators of peer aggression are at increased risk of adverse outcomes. Keeping this theoretical framework in mind it is possible that adolescents become perpetrators of peer aggression to escape strain or a strenuous event in their life. However, perpetrating peer aggression may alienate these adolescents from their peers and teachers, further exacerbating existing strain, causing these perpetrators like victims, to be at increased risk of mental health and substance use problems. An alternative explanation for the increased risk of mental health and substance use problems after involvement in peer aggression is that early adverse experiences (i.e. peer aggression) that occur during vulnerable developmental periods can cause neurobiological changes (Anda et al., 2006 and Shonkoff et al., 2009) expressed as illnesses such as depression in later years (Shonkoff et al., 2009). Currently there are some limitations to the existing studies examining the mental health problems of children and adolescents involved in peer aggression. Initially many studies were cross sectional (Fekkes et al., 2004, Kaltiala-Heino et al., 2000, Nansel et al., 2004, Nansel et al., 2001 and Van der Wal et al., 2003) which prevents the determination of the direction of causality (Reichenheim & Coutinho, 2010). The advantage of more recent longitudinal studies is that they may permit the direction of causality between peer aggression and mental health problems to be inferred. However, the majority of longitudinal studies have only adjusted for mental health problems at the time peer aggression was measured and not for pre-existing mental health problems prior to the age that the peer aggression was measured (Heikkilä et al., 2013, Kaltiala-Heino et al., 2010, Kim et al., 2006, Klomek et al., 2008 and Sourander et al., 2007b). It has been previously shown that children exhibiting emotional and behavioural problems including aggression from as early as 17 months are at an increased risk of becoming a victim or perpetrator of peer aggression in later life (Barker et al., 2008 and Jansen et al., 2011). This aggression in very young children is not necessarily directed towards another child but may consist of behaviours such as destroying toys or temper tantrums (Reebye, 2005). Fisher et al. (2012) suggests that there are individual characteristics such as pre-existing mental health problems that make certain children and adolescents more vulnerable to becoming victims of peer aggression. Incorporating this into their methodology, Fisher et al. (2012) found that after controlling for early internalising and externalising problems at age 5 the association remained between being a victim of peer aggression (at 7 and 10 years) and later self-harm (at 12 years). This current study builds on this premise by additionally controlling for co-existing mental health problems at the age peer aggression was measured and including a broader range of outcomes. By adjusting for pre-existing and co-existing mental health problems, any association between peer aggression and later mental health and substance use problems provides strong evidence of a temporal relationship. The presence of a temporal relationship is one of the required criteria to show that a relationship is causal (Hill, 1965). The aim of the present study was to examine the association between peer aggression (victim, perpetrator, victim-perpetrator) at 14 years and mental health and substance use problems at 17 years using a large prospective longitudinal birth cohort after adjusting for pre-existing mental health problems at 5 years of age, and co-existing mental health and substance use problems at 14 years.
