- Addresses the question of whether it is possible to use a self-report measure of psychopathic traits on non-referred youth samples to identify a subgroup of problematic youths who are particularly problematic and different from other problem youths. A large sample of 1,279 eighth-grade, non-referred adolescents (mean age 14.42 yrs), and their parents were assessed. Students completed self-report measures that assessed personality, conduct problems, and family functioning. Parents responded by completing and mailing in a questionnaire. Results show that the adolescents exhibiting a low-socialized psychopathy-like personality constellation had a more frequent, violent, and versatile conduct-problem profile than other low-socialized and well socialized adolescents. The psychopathy-like adolescents also differed from other poorly socialized adolescents in ways that suggested that their etiological background was different from adolescents with non-psychopathy-like conduct problems. The authors conclude that self-report measures can indeed be useful for research purposes in subtyping youths with conduct problems.

Antisocial behavior in adolescence : the role of individual characteristics
- 2002
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The main aim of this dissertation is to investigate whether traits on the level of the individual are important in understanding violent, frequent antisocial behavior among adolescents. The first of the four studies included in this dissertation asks whether individual-level explanations are going to be a fruitful approach at all. The other three studies speak to the question which particular individual characteristics are related to violent, frequent antisocial behavior. Two different large samples of 14 to 16-year-old male and female non-referred adolescents were assessed. The adolescents were mainly assessed with self-report questionnaires but information from parents and teachers was also incorporated in one of the samples. Results show that aggressive, antisocial behavior for a subgroup of adolescents cuts across social contexts, indicating that their aggressive behavior is largely dependent on individual characteristics, more than on situational factors. It is further shown that a constellation of personality traits involving a grandiose, manipulative interpersonal disposition, callous, unemotional affective traits, and an impulsive, irresponsible behavioral style, characterizes a subgroup of antisocial adolescents who have more violent, frequent antisocial behavior than antisocial adolescents without this personality constellation. This same subgroup also shows more pronounced problem behaviors of other kinds — early behavioral problems, problems with inhibiting aggressive behaviors, and problems with hyperactivity, impulsivity, and attention. Moreover, the results show that the affective facet of this particular personality constellation, involving callous, unemotional traits, plays an important role in violent, frequent antisocial behavior independently of other antisocial-related dimensions such as impulsivity, hyperactivity, and sensation seeking traits. Importantly, the main findings were similar for males and females. It is concluded that specific personality traits are important to consider when moving further toward an understanding of violent, frequent antisocial behavior and that research on non-referred, community samples of youths can be particularly helpful for this purpose. Implications for prevention and intervention and directions for future research are discussed.

- Examined the relationship between bullying in school and street violence. 2,915 adolescents (aged 14-15 yrs) completed questionnaires concerning street violence, weapon carrying, violence victimization, loitering, bullying, and nights away from home. Results show that bullying others in school was strongly linked to violent behavior and weapon-carrying on the streets, both among males and females. Bullying others in school was also related to being violently victimized on the streets. Findings suggest that school bullying is in many cases a part of a more general violent and aggressive behavior pattern, and that preventive efforts targeting individuals with bullying behavior in school may decrease violence among adolescents in the community as well.

Tidskriftsartikel (refereegranskat)abstract
- Objective: In the present paper we ask whether it is meaningful to study psychopathic traits in non-referred youths and whether this kind of research can be used to understand the development of criminal full-blown psychopathy. Method: We review studies that have investigated the utility of assessing psychopathic traits in non-referred samples of youths. Results: Research shows that psychopathic traits in non-referred youths manifest similarly to how they are manifested among incarcerated offenders, as indicated by similarities in factor structures. Also, psychopathic traits relate similarly to frequent, violent antisocial behavior in non-referred youths as among adult and adolescent institutionalized criminal offenders. Thus, the differences between the non-referred conduct-problem youths exhibiting a psychopathic personality pattern and the incarcerated, criminal youths identified as psychopathic seem to be quantitative rather than qualitative. Conclusion: It is concluded that research on non-referred youth samples can provide important knowledge about the processes that underlie the development of psychopathic traits and how this development can be prevented. Implications for future research and intervention and prevention are discussed.

The rhythm of adolescence : morningness-eveningness and adjustment from a developmental perspective
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In recent developmental research, sleep-wake patterns and preferences, in other words Morningness-Eveningness, have been shown to be related to various kinds of problem behavior. Previous research on adolescents has demonstrated that individuals with a sleep-wake preference toward staying up late in the evening and arising late in the morning (i.e., Eveningness), are more likely to face problems in development. Accordingly, Eveningness has been proposed as a risk factor in development, but through processes which researchers have not been able to fully explain. The present dissertation focuses on the relationship between Morningness-Eveningness and developmental patterns across contexts in adolescence. Links between Morningness-Eveningness, and negative adjustment, life style, personality characteristics, family relationships, peer networks, and school achievement, are discussed within an interactionistic framework. Also, factors that might explain and/or moderate these associations are elucidated. The empirical material stems from two cohorts of 8th grade adolescents in a middle size Swedish community. Eveningness is proposed to be a concurrent marker of risk behavior. However, there seems to be different kinds of Evening types that encounter different kinds of problems. Also, the present findings do not support the notion of Morningness being protective. How temporal patterns in general, and Eveningness in particular, are connected to other behaviors is emphasized as important knowledge for stemming negative developmental processes and facilitating positive outcomes.

At first blush : the impact of shyness on early adolescents' social worlds
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Shyness as a behavioral characteristic has been in focus of research in psychology for a number of decades. Adolescent shyness has, however, been relatively overlooked compared with studies conducted on children and adults. This dissertation concentrated on adolescent shyness, aiming to attain a better comprehension about how shyness during this developmental phase might affect, and be affected by social relationships. The first aim of this dissertation was to study in which way shyness influences and is influenced by significant people in adolescents’ lives: peers, friends, and parents. Study III showed that shy youths socialized each other over time into becoming even more shy. Study VI demonstrated that youths’ shyness affected parenting behaviors, more so than parent’s behaviors affected youth shyness. The second aim of this dissertation was to investigate what shyness means for adolescents’ choices of relationships with friends, whereas the third aim focused on whether adolescents’ ways of dealing with peers would have consequences for their internal and external adjustment. As Study I showed, youths might take on off-putting, startling appearances in order to cope with their shyness. This strategy seemed, nonetheless, not particularly successful for the shy youths in terms of emotional adjustment. Study III showed that adolescents who were shy tended to choose others similar to themselves in shyness as friends. Study II showed that shyness might indeed have some positive implications for adolescent development, as it was found to serve a protective role in the link between advanced maturity and various types of problem behaviors. Overall, the findings point to some gender differences regarding all of the abovementioned processes. In sum then, the studies in this dissertation show that even though youths’ shy, socially fearful characteristics affect their emotional adjustment and those around them, shy youths are part of a larger social arena where they are active agents in shaping their own development. Although adolescent shyness might be linked with several negative outcomes, however, it might be other people’s reactions to socially fearful behaviors that help create and/or maintain these outcomes over time.
