In this study, we sought to determine if the "Scales for Assessing Emotional Disturbance -- Third Edition" ("SAED-3"; Epstein et al., 2020) demonstrated adequate validity using criterion validation techniques. The associations between the "SAED-3" subscales and composite scores were examined in relation to similar…

Behavioral correlates to happiness (i.e., indices of happiness) have been used as means of measuring happiness in individuals with developmental disabilities. However, research has not yet evaluated the possibility that indices of happiness/unhappiness (IHUs) may signal the presence of a setting event that could affect other behaviors. The purpose…

The increasing usage of social media has sparked interest in identifying characteristics that contribute to problematic social media use (PSMU). Using the Interaction Person-Affect-Cognition-Execution (I-PACE) model, the current study analyzes whether fear of missing out (FoMO) and dissociative experiences affect the link between trait emotional…

The mental health and well-being of children and adolescents are critical public health concerns globally. This cross-sectional study analysed nationally representative data from the combined 2016-2022 National Survey of Children's Health (n = 239,534) to produce estimates of parent-reported diagnoses of children's anxiety, depression and…

This study used latent transition analysis to examine the stability and change in perceived threats in youth's primary social contexts--neighborhoods, schools, and families--and associations with emotional and behavioral problems when youth transitioned from childhood to adolescence. The sample included 8208 racially and ethnically diverse youth…

Previous research has indicated that student mental health is linked to their engagement at school. However, there is a lack of empirical studies examining students' school engagement from the more comprehensive dual-factor model, which assesses both psychopathology and subjective well-being [SWB]. The current study examined this relationship via…

Recent work indicates clinically meaningful differences in domains of psychopathic personality -- such as grandiose-manipulative (GM), callous-unemotional (CU), and daring-impulsive (DI) traits -- and parenting factors. Yet, different domains of parenting and reports from multiple informants may vary in their associations to psychopathic traits.…

Background: Children with neurodisabilities, including those with intellectual and developmental disabilities (IDD), autism and other complex needs, frequently experience sleep disturbances, impacting their health, behaviour and caregiver well-being. This study evaluates the effectiveness of Cubby Beds, sensory safety beds designed to improve…

Purpose: The study objective was to determine if the validated Behavioral Inflexibility Scale (BIS) is sensitive to the detection of developmental changes in inflexibility in a sample of autistic children. Methods: Parents of autistic children (n = 146, 3-17 years) completed the BIS at two time points, one year apart, to examine change. Results:…

This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

In this systematic review, we aimed to identify the impact of the COVID-19 pandemic on children/adolescents with a diagnosis of autism spectrum disorder (ASD). The protocol was registered on PROSPERO CRD42021255848. Articles were selected from PubMed, Embase, and LILACS according to these characteristics: patients from zero to 18 years old,…

This study explored how caregiver-reported executive functioning domains, assessed by the BRIEF2 at baseline, predicted behavioral challenges reported by caregivers using the CBCL six months later. The sample included 94 youth with Down syndrome, aged 6 to 18 years. Results of hierarchical regression analyses revealed that, after controlling for…

Non-suicidal self-injury (NSSI) is a significant public health concern, with severely impacts for adolescent mental health. As awareness of the harmful effects of NSSI grows, there is an increasing emphasis on understanding the underlying mechanisms in this age group. This study explores how internalizing and externalizing issues related to…

Problematic internet use (PIU) has become a noticeable issue among adolescents, which negatively affects their physical and mental health. Previous research has noted the protective role of school climate in reducing PIU, but the underlying mechanisms need to be further explored. Based on the ecological systems theory, this study focused on the…

Toward the development of a new parent-rating for insomnia, this multi-site qualitative study explored sleep problems and related impacts in children with autism spectrum disorder (ASD) and their families. To ensure content validity of the measure, we conducted six focus groups with caregivers (N = 25) of 24 children (age 3 to 18 years) with ASD.…
