Children and adolescents display varying trajectories of conduct problems (CP), but it is unclear if these CP trajectories can be distinguished by childhood antecedents and adolescent outcomes. Therefore, we tested if child- and environmental-level risk factors predict CP trajectory membership and if CP trajectories are associated with developmental outcomes in adolescence. Six waves of data (teacher-, parent- and child self-reports) were used from 2,045 children.

Conduct problems (CP) in childhood and adolescence have a significant impact on the individual, family, and community. To improve treatment for CP, there is a need to improve the understanding of the developmental pathways leading to CP in boys and girls. Prior research has linked the child's fearlessness and callous-unemotional (CU) traits, as well as experiences of parental warmth and punitive parenting, to CP.

Psychopathic traits in childhood have been revealed as potential identifiers of risk, being predictive of later forms of behavioral maladjustment. Yet, it is still under debate how psychopathic traits in children should be best conceptualized and which are the core dimensions for construct definition and prediction. The present study aims to examine the structure of psychopathic traits in childhood, and its predictive value, by using a combination of traditional factor analysis and more recent network-based methods.

Article Synopsis
  • Research investigated the link between externalizing behaviors (like violent/nonviolent crime and substance use disorders) in individuals born between 1973 and 1997 and the risk of Alzheimer's disease (AD) or dementia in their family members.
  • A nationwide study with over 2.4 million people showed that parents of those with such behaviors had a significantly higher risk of developing AD compared to parents without those behaviors.
  • Findings suggest that shared genetic and environmental factors may underlie both externalizing behaviors and the development of AD or dementia, prompting the need for further studies in this area.

Article Synopsis
  • This study explores new ways to classify children with conduct problems (CP) by proposing three traits: grandiose-manipulative, daring-impulsive, and callous-unemotional, rather than relying solely on callous-unemotional traits.
  • Researchers used data from community studies in Sweden and Spain, measuring these traits in young children and assessing their developmental outcomes years later through input from teachers, parents, and the children themselves.
  • Results showed that while all traits were linked to various developmental outcomes, callous-unemotional traits were effective in predicting social competence issues, whereas grandiose-manipulative and daring-impulsive traits were associated with aggression and delinquency, suggesting a need for careful evaluation before making changes to existing diagnostic criteria.

This study investigates whether the longitudinal association between fearlessness and conduct problems (CP) is mediated by warm and harsh parenting, parent-child conflict, anxiety, and callous-unemotional (CU) traits. The constructs under investigation were assessed at five different time points, spanning a period of eight years. A multi-informant approach was followed, collecting data from parents and teachers (N = 2,121; 47% girls).

Criminal behaviour has previously been associated with an increased risk for several mental health problems, but little is known about the association between criminal behaviour and dementia. We aimed to examine how the criminal background (type of crime, number of convictions, length of the sentence) is associated with dementia and mild cognitive impairment (MCI), and how mental and physical health disorders and educational attainment influenced these associations. A nationwide cohort of 3,617,028 individuals born between 1932 and 1962 were linked with criminal and medical records using Swedish national registers.

Studies on the psychopathy construct are mostly limited to Western cultures, and there is a lack of research in this area in non-Western countries, specifically in Iran. The present study aimed to examine the factor structure, internal consistency, and convergent validity of the Persian version of the Youth Psychopathic Traits Inventory-Short Version (YPI-S) with a sample of 668 school-attending adolescents in Iran (46% girls; M = 16.35).

Background: Previous research has indicated that attention-deficit/hyperactivity disorder (ADHD) is associated with an increased risk for dementia, but studies are scarce and inconclusive. We aimed to investigate the association between ADHD, and dementia and mild cognitive impairment (MCI). Additionally, we aimed to investigate the impact of comorbid conditions, educational attainment, head injuries, other developmental disorders, and sex on the association.

Presence of meaning in life is an important component of eudemonic wellbeing while aging. While subjective health and interpersonal relationships are among important sources of meaning for older adults, less research has explored the gender differences in the potential contribution of these sources to the presence of meaning in late life. The current study aims to examine the associations of frailty dimensions (daily activities, health problems, and psychosocial functioning) and social support with the presence of meaning in late life, and whether these associations differ for older men and women.

Fear of crime is a substantial problem for older adults and is associated with reduced subjective well-being. However, less is known about factors that could moderate the associations between fear of crime and mental health problems and well-being in advanced age. Cognitive emotion regulation could serve as a potentially buffering factor for adverse health outcomes related to fear of crime due to its potential importance in managing feelings when facing threatening situations.

Objective: A limited prosocial emotions (LPE) subtype of conduct disorder (CD) has been added to the DSM-5. Empirical studies on this categorically defined subtype are scarce, and existing work is predominantly cross-sectional. Hypotheses surrounding the LPE subtype that relate to comorbidity, prognosis, and developmental antecedents, and overlap with psychopathic personality, have received no or little scrutiny.

There is a significant knowledge gap in research on Attention-Deficit/Hyperactivity Disorder (ADHD) in older adults. Via a systematic review and meta-analysis, we aimed to investigate the prevalence of ADHD in older adults, considering different assessment methods. We searched five electronic databases up to June 26, 2020.

A systematic review with meta-analysis was performed to: 1) estimate the prevalence of both mental and physical health problems in older offenders; 2) calculate relative risks for the health conditions in relation to non-offender older adults and; 3) explore the potential confounding role of several variables. We searched five databases up to August 2019. Studies involving offenders older than 50 years old were included.

In the current study, we tested the relations between cyberbullying roles and several psychological well-being outcomes, as well as the potential mediation effect of perceived social support from family, friends, and teachers in school. This was investigated in a cross-sectional sample of 1707 young adolescents (47.5% girls, aged 10-13 years, self-reporting via a web questionnaire) attending community and private schools in a mid-sized municipality in Sweden.

The importance of Vesicular Glutamate Transporter 2 (VGLUT2)-mediated neurotransmission has been highlighted in studies on addiction-related phenotypes. The single nucleotide polymorphism rs2290045 in VGLUT2 has been associated with alcohol dependence, but it is unknown whether or how this association is affected by environmental factors. The present study determined whether the association of alcohol-related problems with the rs2290045 in the VGLUT2 gene was modified by negative and positive environmental factors.

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.

Children with early-onset conduct problems (CP) are at great risk for future behavior problems, and this risk seems to increase when CP co-occur with psychopathic traits. Even though studies are indicating that the entire psychopathic personality construct may be more useful in designating a meaningful subgroup of children with CP, research on psychopathic traits and CP in childhood have mainly focused on the role of callous unemotional (CU) traits. Prospective longitudinal data of 1867 3- to 5-year-olds (47% girls) followed annually for two years was used to compare groups of children with different combinations of CP and psychopathic traits on fearlessness and Attention-Deficit Hyperactivity Disorder (ADHD) symptoms.

The aim of this study was to compare callous-unemotional (CU) traits versus the multidimensional psychopathy construct in their ability to predict future and stable antisocial behavior. At baseline, a community sample of 996 Cypriot 12-year old adolescents (52% girls) completed measures that tap conduct problems (CP) and psychopathic traits, including CU. CP, aggression, and substance use were self-reported at 1-3 year follow-ups.
