Journal article (peer-reviewed)abstract
- In this article, we give a presentation of the longitudinal research program Individual Development and Adaptation (IDA) that can be helpful as a template for researchers considering to launch their own longitudinal studies, and that opens the door to IDA for researchers looking for suitable data to be analyzed within their own project or in collaboration with IDA. We also introduce the holistic-interactionistic theoretical framework of IDA and the associated person-oriented approach – an approach that is especially suited for analyzing the rich IDA data set with its broad coverage of different areas of adjustment and related factors. The paper provides an overview of the essential features of the IDA database, as well as of ongoing and planned IDA research

- Objective: To explore whether children with various externalizing/prosocial behavior profiles benefit differently from face-to-face training than from an internet-based parent management training (PMT) programme. Methods: A total of 231 families with children (aged 10 to 13 years) with externalizing behavior problems (EBP) were randomized to receive either the Family Check-Up, delivered by therapists in the community, or the internet-based PMT program (iComet). Person-oriented analysis was used for subtyping the children according to combinations of prosocial behavior and EBP. Results: The person-oriented analysis resulted in five significantly different clusters. There were no significant differences between the five clusters in relation to the total difficulties score of the Strengths and Difficulties Questionnaire, family warmth or family conflict, but the within-group effect sizes for the main outcome (total difficulties score) from baseline to post-treatment varied from Cohen’s d of 0.52 to 2.56. There were no significant interaction effects between the clusters and type of intervention. However, for children high on symptoms of attention deficit hyperactivity disorder and moderate to high on oppositional defiant disorder, and low to relatively high on prosocial behaviors (Cluster 3 respectively 5), substantial residual EBP-symptomatology remained at post-treatment, although both interventions resulted in significant effects. The other three clusters were within the non-clinical EBP-range at post-intervention, irrespective of treatment condition. There were no significant differences between the clusters regarding treatment completion rate (ranging from 47.2% to 67.4%). This study illustrates the value of distinguishing between different profiles of children in the context of PMT for parents of children with EBP.

A bad start: The combined effects of early onset substance use and adhd and cd on criminality patterns, substance abuse and psychiatric comorbidity among young violent offenders

Journal article (peer-reviewed)abstract
- © 2020, Lundh Research Foundation. All rights reserved. Substance abuse, conduct disorder (CD) and attention deficit/hyperactivity disorder (ADHD) are all known risk factors for developing aggressive behaviors, criminality, other psychiatric comorbidity and substance use disorders (SUD). Since early age of onset is important for aggravating the impact of several of these risk factors, the aim of the present study was to investigate whether young adult violent offenders with different patterns of early onset externalizing problems (here: substance use < age 15, ADHD, CD) had resulted in different criminality profiles, substance use problem profiles and psychiatric comorbidity in young adult age. A mixed-method approach was used, combining a variable-oriented approach (with Kruskal Wallis tests) and a person-oriented approach (with Configural frequency analysis). Overall, this combined approach indicated that persons with combined ADHD+CD and persons with CD + early onset of substance use had a more varied history of violent crimes, a more comprehensive history of aggressive behaviors in general, and more psychiatric comorbidity, as well as more varied SUD and destructive substance abuse in adult age, than persons without ADHD, CD or early SU. Results are in line with previous variable-oriented research, but also indicate that individuals in this group with heavy problem aggregation early in life have a wider spectrum of problems in young adult age. Importantly, among these young violent offenders, problem aggregation was the overwhelming norm, and not the exception, as in studies of the general population. This emphasizes the need for early coordinated interventions, but also that treatment within correctional facilities in adult age needs to be comprehensive and take individual patterns of comorbidity into account.

Journal article (peer-reviewed)abstract
- Purpose: Perfectionism has been found to predict outcomes in the treatment of eating disorders (ED). In the present study, we took advantage of longitudinal data to:a) investigate whether thereare different patterns of perfectionism during the first six months after admission in a clinical sample of patients with ED, and b) describe how these patterns are related to long-term outcome.Methods: A sample of patients (N=294) fromthe Coordinated Evaluation and Research at Specialized Units for Eating Disorders database was divided into clusters according to perfectionism patterns measured with the EDI-2 perfectionism scale at baseline, and six months in treatment. Cluster analysis was performed on the extent and perseverance/changeability of self-oriented and socially described perfectionism. Outcome was measured with the EDI-2 and the SCL-63. Frequencies of eating disorder diagnoses were investigated.Results: Five clusters were identified. Low perfectionism was associated with lower levels of ED and psychiatric symptomatology at baseline. There were nosignificant differences between clusters on outcome variables at 36-month follow-up.Conclusions: Results indicated better psychiatric and psychological health three years after the initial measure. Patterns of relations between the extent and possible changes of perfectionism, measured with the EDI-P at baseline and after six months, did not appear to be associated with long-term outcomes on psychiatric health ratings.

Stability and Change in Patterns of Adolescent Antisocial Behavior

Journal article (peer-reviewed)abstract
- Research examining relations between various types of antisocial behavior (ASB) have generally been based on cross-sectional data. Although there is a strong correlation between types of ASB, it has been less common to examine how patterns of adolescents’ problems vary over time. This study used a person-oriented approach to examine patterns of ASB in adolescents longitudinally and also investigated how these patterns were associated with three outcomes. The sample con-sisted of 778 Swedish adolescents in grade 7 (13 years old) followed over time to grade 9. Patterns of ASB were identified based on adolescent-reported tobacco and alcohol use, truancy, bullying in school, and delinquency. The outcomes were drug use, depressive symptoms, and missing grades in grade 9. Results revealed an escalation in the frequency and seriousness of ASB over time, although the largest single cluster over time evidenced no ASB. One cluster in particular increased the risk of drug use, depression, and missing grades at grade 9. Results are discussed in relation to school-based prevention efforts.

Adolescent girls in context : Not all patterns may be created equal

Journal article (peer-reviewed)abstract
- Much research exists on the importance of risk factors within individual contexts of parenting, neighborhood, school, and peers for adolescent development. However little exists on whether risks in certain contexts may be more or less likely for risk accumulation across contexts – referred to as the Weighted Risk Phenomenon (WRP). One way to study WRP is to study adolescent patterns of co-existing risk characteristics across domains and over time. The present study focuses on studying information about parenting, neighborhood, school, and peers in order to understand how risk can have different patterns over time. Participants were all girls recruited from junior high schools in rural and metropolitan areas of Sweden. The results illustrate that there are stable structural and individual pathways across four contexts of adolescent girls which may represent risk over time. Structurally, patterns which emerged at grade 7 reappeared again a year later and again a year after that in grade 9. In general, the same individuals seem to re-emerge in the same or similar patterns over time. Those who showed risk accumulation patterns tended to report prior risk factors in the parenting context. Such trends are supported in the literature and give support to the postulation that parenting is one of the strongest risk factors for adolescents. The findings indicate possible underpinnings of WRP.
