Adolescents at risk of persistent antisocial behaviour and alcohol problems : The role of behaviour, personality and biological factors
- 2005

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Antisocial behaviour and alcohol problems are areas of great concern to society, not only associated with personal and emotional costs for the affected individuals and their victims, but also with major societal financial costs. What makes some individuals more likely than others to develop these kinds of problems? The general aim of this thesis was to explore the role of individual characteristics in the development of antisocial behaviour and alcohol problems. More specifically, the research focused on aspects of hyperactive behaviour, personality traits and biological vulnerability indicators in relation to self-reported norm breaking and violent behaviour, registered general criminality and violent offending in particular, and further, on risky alcohol use and drinking offences. The studies were based on both a prospective longitudinal project in which a group of adolescent male lawbreakers and controls were followed from the 1960s into the 1990s, and on more recently collected data on a representative group of Swedish male and female adolescents.The results of the thesis supported that neuropsychological deficits, manifested in attention difficulties, and personality traits reflecting disinhibition and negative emotionality, influence the development of antisocial behaviour and risky alcohol use, which in turn increases the risk of subsequent alcohol problems. The findings indicated, furthermore, that these neuropsychological deficits may be associated with an underlying biological vulnerability to various forms of disinhibitory psychopathology. Although the thesis focuses on individual characteristics, the results also support the view that environmental risk factors such as the influence of family and peers and possible stress experiences, play an important role. It was emphasized that individual characteristics continuously interact with environmental conditions in shaping each individual’s developmental course. Results also revealed that adolescent females displaying violent behaviour and engaging in potentially harmful use of alcohol deviated more in personality traits than did the corresponding group of males. Further knowledge of the development of these problems in females is crucial, since most theories in this area have been developed primarily on male samples.

- Previous research shows that a disadvantaged school setting is associated with increased risk of adolescent delinquency. However, there is limited research on individual differences in such contextual effects. In this study, we investigated whether the association between impulsive and sensation-seeking traits and delinquency is modified by the school setting, focusing on schools’ socioeconomic and ethnic composition and average school performance. We also examined whether the association between gender and delinquency varies by school context. Participants were adolescents in ninth grade from the Stockholm School Survey (5619 pupils in 89 schools). The findings showed an attenuating effect of school advantage on adolescents’ individual risk of delinquency. Impulsive and sensation-seeking adolescents, and boys in particular, committed less crime if they attended more advantaged schools.

- The present study focused on personality characteristics in adolescent boys (n = 414) and girls (n = 552) in 8th grade with self-reported violent behavior and risky alcohol use. Adolescents with indications of violent behavior and/or risky alcohol use, compared to others, were generally more impulsive, had a stronger need for change and action, were less adjusted and socially conforming, as well as more aggressive. The findings pointed toward a clustering of problem behaviors. Furthermore, adolescents with a combination of violent behavior and alcohol use had more pronounced personality scores than subjects who reported only one of these behaviors. The main finding was that among girls these behaviors appeared to be associated with more deviant levels of the personality characteristics in focus.

Romantic relationships and delinquent behaviour in adolescence : the moderating role of delinquency propensity

- There is some evidence that adolescent romantic involvement is associated with delinquent behaviour. One aim of this longitudinal study was to determine whether this holds for romantic relationships deemed important by the participants. A second aim was to test whether this association was stronger for adolescents with pre-existing delinquent behaviour and personality traits of impulsivity and thrill seeking (delinquency propensity). Sex differences also were examined. Participants were 686 7th and 8th grade students who completed three assessments over three years. The results showed that delinquency was associated with earlier romantic relationships among those who were higher in delinquency propensity one year earlier. This association was stronger among girls than boys. Thus, romantic relationships amplified girls' and boys' existing delinquency propensity, but this was strongest among girls.

Tidskriftsartikel (refereegranskat)abstract
- With Moffitt's developmental typology of antisocial behavior as a starting point, the general aim of the study was to investigate the stability of and change in criminal behavior from early adolescence to early adult age. The purpose was also to explore the role of individual, family, peer and school related risk factors in the development of criminal behavior. The study was based on data from the prospective longitudinal research project ‘Young Lawbreakers as Adults’, in which a group of adolescent male lawbreakers and controls were followed from the 1960s into the 1990s. The results were in favor of a distinction between adolescencelimited and persistent criminality, and supported the suggestion of a common set of risk factors dimensionally related to offending, rather than trajectory-specific risk factors. The findings indicated that, in addition to these common risk factors, early attention deficits and manifestations of aggression might be of specific importance to persistent criminality.
