Cornelia de Lange syndrome (CdLS) is associated with repetitive and self-injurious behaviors (RBs, SIB). Evaluating children with CdLS, this study: (1) characterizes the spectrum of RBs; (2) characterizes the impact and severity of RBs including SIB; (3) describes how age and adaptive functioning relate to RBs including SIB. Fifty children…

Understanding barriers to treatment-seeking among college students with suicidal ideation (SI) is critical to campus suicide prevention efforts. We used data from the Healthy Minds Study to test for gender and racial/ethnic differences in self-reported barriers to professional help-seeking among college students with past-year SI. Students (n…

Previous research suggests that nonsuicidal self-injury (NSSI; the intentional destruction of bodily tissue without suicidal intent) occurs among elementary-aged children. However, it remains unclear to what extent elementary school educators encounter NSSI among students and how they respond. Therefore, this study investigated cross-national…

Objective: Increased demands during the transition into college can negatively impact students' physical and mental wellness, and increase risk of suicide. A supportive campus culture that promotes social connectedness and meaningful engagement may amplify wellness and prevent suicide. This study explored whether involvement in extracurricular…

Traditional self-injurious behavior (SIB) management can place compliance demands on the caregiver and have low ecological validity and accuracy. To support an SIB monitoring system for autism spectrum disorder (ASD), we evaluated machine learning methods for detecting and distinguishing diverse SIB types. SIB episodes were captured with body-worn…

The goal of the current analyses was to explore associations of self-rated physical attractiveness with facets of psychological well-being across adolescence. Participants provided information on their perceived physical attractiveness, internalized distress, suicidal ideation, and self-harm at 15, 17 and 20 years of age. Male adolescents…

Research on bullying victimization has expanded to specific forms of harassment based on discriminatory bias, which involve aggressive behavior targeting an individual's identity characteristics, such as sexual orientation and/or gender expression. Recent studies have documented elevated health risks associated with victimization based on…

Restricted interests and repetitive behaviors (RRBs) are core symptoms of autism spectrum disorder (ASD), and commonly occur in attention-deficit/hyperactivity disorder (ADHD). Little is known about how RRBs manifest in ADHD. We quantified and compared factor structures of RRBs in children with ASD (n = 634) or ADHD (n = 448), and related factors…

Self-injurious behaviors (SIB) are elevated in autism spectrum disorder (ASD) and related genetic disorders, but the genetic and biological mechanisms that contribute to SIB in ASD are poorly understood. This study examined rates and predictors of SIB in 112 individuals with disruptive mutations to ASD-risk genes. Current SIB were reported in 30%…

Self-injurious behaviour is purportedly common in autism, but prevalence rates have not yet been synthesised meta-analytically. In the present study, data from 14,379 participants in thirty-seven papers were analysed to generate a pooled prevalence estimate of self-injury in autism of 42% (confidence intervals 0.38-0.47). Hand-hitting topography…

Self-harm is purportedly common in autistic individuals, but under-researched, particularly in younger samples and those "without" intellectual disability. This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n =…

This study investigated rates of suicidal ideation (SI) and suicidal and/or self-injurious behaviour (SSIB) reported by parents on the Child Behavior Checklist for 178 children with ASD over four annual assessments (ages 7-11 years). Analyses examined the frequency and persistence of SI and SSIB, and the association of SI and SSIB at any time…

This study explored racial differences in internalizing and externalizing problems among minority adolescents in impoverished urban communities. The study centered on a sample of 211 participants who were engaged in the 2018 Building Resilience Against Violence Engagement (BRAVE) programs. Their internalizing and externalizing problems were…

Support from parents and school staff are important for adolescent well-being. However, few studies have examined the role of parental involvement and adult social support at school on high school students' mental health, specifically, suicidal thoughts and behaviors (STBs). Data were collected from 362,980 high school students (51.85% female)…

Elevated salivary cortisol levels have been documented in individuals who engage in self-injurious behavior (SIB), indicating acute physiological stress. Less is known about the chronicity of stress and SIB. We analyzed the relationship between parent ratings of problem behavior and hair cortisol concentrations (an index of chronic adrenocortical…
