- Aims: The overall aim was to study patterns of delinquent behaviour in relation to adolescent alcohol use. The more specific aims were to examine whether alcohol use varied between groups of adolescents with different patterns of delinquent behaviour, and to explore whether the association between delinquent behaviour patterns and alcohol use was similar for males and females.Methods:The participants were male (n = 406) and female (n = 532) adolescents in the eighth grade (age 14 years) in a medium-sized city of Sweden. We used information about self-rated alcohol use and different types of delinquent behaviour. Results: The results revealed that the occurrence of excessive alcohol use and drunkenness varied between groups of adolescents with different delinquency patterns, and that the associations between alcohol use and patterns of delinquent behaviours were relatively similar for males and females. Adolescents with patterns characterized by more serious non-violent delinquency or by violent delinquency reported the highest occurrence of alcohol use and frequency of drunkenness. Adolescents with well-adjusted behaviour or occasional minor delinquency were less likely to report drinking large amounts of alcohol or to the point of feeling drunk. Conclusions: The present results further emphasize the importance of distinguishing between different offender groups when examining the relationship between delinquent behaviour and associated problems, such as excessive alcohol use.

- The present study examined subgroups of delinquent adolescents and the short-term development of delinquency and personality traits characterizing these subgroups. Participants were girls and boys examined at the beginning of the 8th grade and followed up at the end of the 9th grade (n = 901). Four delinquency subgroups were identified for boys and for girls on both occasions, primarily characterized by well-adjusted behaviour, minor delinquency, serious delinquency or violent delinquency. The findings indicated that most adolescents displaying a certain delinquency pattern in 8th grade displayed a similar delinquency pattern in 9th grade. However, boys and girls involved in minor delinquency, and boys involved in violent delinquency, were more likely than expected to develop serious delinquency over time, indicating a progression towards more serious and versatile delinquency. Delinquent adolescents were in general more disinhibited, less adjusted and conforming, and more aggressive than well-adjusted adolescents, whereas boys in the serious delinquency subgroup and girls in the violent delinquency subgroup also were characterized by somatic anxiety. The findings support making a distinction between antisocial behaviour subgroups and indicate some personality traits associated with certain subgroups of delinquent adolescents.

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.

- 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.

- 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.
