Objective: Alcohol use is a substantial problem among college students and has several negative consequences. The current study examined the associations between anhedonia and alcohol use and related problems "via" impulsive behavior (e.g., negative urgency, sensation seeking). We parsed anhedonia into four specific facets: consummatory,…

Adolescent marijuana use has become increasingly more problematic compared with the past; thus, understanding developmental processes that increase the liability of marijuana use is essential. Two developmental pathways to adolescent substance use have been proposed: an externalizing pathway that emphasizes the expression of aggressive and…

Objective: Problem-drinking among university students is common and poses serious health-related risks. Therefore, identifying and addressing associated factors is important. Participants and methods: A large cross-sectional online-survey with 12,914 university students from Berlin was conducted from November 2016 to August 2017. Relative-risk-…

To investigate the contribution made by autistic children's Challenging Behaviour (CB) to their parents' anxiety and depression, parents of 32 autistic boys and 32 autistic girls (aged 6 to 18 years) completed standardised instruments on their children's behaviour and their own anxiety and depression. Significant associations were found between…

Objectives: Researchers examined associations between specific forms of emotion dysregulation and numerous behavioral manifestations of impulsivity (i.e., problematic alcohol use, drug use, risky sexual activity, binge eating, non-suicidal self-injury). Participants: Participants were 238 undergraduate students (69% female). Method: Emotion…

Growing evidence demonstrates associations between child race, teacher-child race match, and teacher ratings of externalizing behaviour problems in the early years of school. The present study deepens understanding of the relations between child, teacher, and classroom racial factors and teacher-reported externalizing behaviours by examining…

Adults with autism spectrum disorder often experience co-occurring mental health problems such as attention-deficit/hyperactivity-disorder, as well as impairments in executive function. Sluggish cognitive tempo, a cluster of behaviors including slow processing, daydreaming, and mental fogginess, has been shown to be associated with…

Introduction: The primary aim of this retrospective study was to assess differential associations between sleep disturbances with externalizing/internalizing problems, ADHD profiles (inattention, hyperactivity/impulsivity), and social impairment among children with ADHD, autism spectrum disorder (ASD), and comorbid diagnoses (ASD+ADHD). Methods:…

Background: In the general population, sleep problems have an impact on daytime performance. Despite sleep problems being common among children with Down syndrome, the impact of sleep problems on daytime behaviours in school-age children with Down syndrome is an understudied topic. Our study examined the relationship between parent-reported and…

A growing body of research has acknowledged the heterogeneity of subclinical social anxiety, identifying a subgroup of individuals who exhibit high levels of impulsivity. In a sample of Swedish early adolescents (N=2,509, M[subscript age]=13.64; 52.8% girls), we conducted latent transition analyses (LTA) to identify four classes of subclinical…

This study investigated categories of autism spectrum disorder (ASD) symptoms measured by the Autism Diagnostic Observation Schedule-Second Edition and their association with maternal stress. Social affect and restricted and repetitive behaviors were compared with levels of maternal stress, measured by the Parenting Stress Index, in 102 children…

Background: There is limited research documenting the health and/or psychological services accessed by adults with rare genetic syndromes who engage in challenging behaviour. The study documented service receipt and associations with person characteristics. Method: Thirty-two parents of adults with rare genetic syndromes completed an adapted…

Research on the role of puberty in adolescent psychological development requires attention to the meaning and measurement of pubertal development. Particular questions concern the utility of self-report, the need for complex models to describe pubertal development, the psychological significance of pubertal timing vs. tempo, and sex differences in…

Despite increasing interest in sluggish cognitive tempo (SCT) in children, the field is stymied by the lack of a standard symptom set that can be used across studies. Without a standard symptom set, it is difficult to determine if differences across studies are due to methodological or sample differences, or simply the way SCT was measured. To…

Young adults with attention-deficit/hyperactivity disorder (ADHD) symptoms are more likely than their peers to engage in risk-taking behaviors, including harmful alcohol use, consumption of illicit drugs, and risky sexual behaviors. These behaviors become more common in the general population of young adults as they enter college, particularly for…
