This study aimed to identify and reach a consensus on factors contributing to adolescent suicidality following biopsychosocial model. The research was conducted in three stages: (1) literature review and school counselor interview on self-harm and suicidal risk factors in the adolescent population; (2) development of a list of risk factors (3)…

Suicide has been identified as a leading cause of premature death in autistic populations. Elevated autistic traits have also been associated with higher rates of self-harm, suicidal ideation, and suicidal self-harm in the general population, but this has yet to be examined in older age. Using baseline cross-sectional data from the PROTECT study,…

Background: Suicidality in individuals with intellectual disability is a critical but under-researched area. This systematic review aims to synthesize existing literature on the prevalence, risk factors, and interventions for suicidality among individuals with intellectual disability. Methods: Adhering to the PRISMA guidelines, a comprehensive…

Background: Adolescent self-harm is a major public health issue internationally. Various factors associated with adolescent self-harm have been identified, including being bullied and experiencing mental health problems. Stuttering and speech sound disorder are associated with both of these factors. It was hypothesized that both stuttering and…

Objective: The current study evaluated frequency of nonsuicidal self-injury (NSSI) and associated maladaptive traits between three time periods: pre-pandemic, early pandemic, and later pandemic. Participants: Two college student samples (n = 362; n = 337) were collected via two online studies. Method: Participants completed measures assessing…

Background: Longitudinal research is needed to strengthen evidence for risk factors for challenging behaviour in children with intellectual disabilities and to understand patterns of change over time. Methods: Data on challenging behaviour were collected for 225 students in one school over four annual time points and a range of potential risk…

Objective: The current study aimed to better understand the relationship between exposure to non-suicidal self-injury (NSSI) through peers, group conformity characteristics (i.e., over-dependency, need-to-belong), and personal NSSI engagement. Methods: One hundred thirty-eight undergraduate students (n = 40 with history of NSSI) completed an…

Self-injurious behavior (SIB) is inherently problematic because it can lead to injuries, including those that are quite severe and may result in loss of function or permanent disfigurement. The current study replicated and extended Rooker et al. (2018) by classifying the physical characteristics of injuries across groups of individuals with…

Suicidal thoughts and behaviors and nonsuicidal self-injury are more common in autistic adolescents than non-autistic adolescents, per parent- and self-report. Clinician-rated measures of suicide risk (e.g. Columbia Suicide Severity Rating Scale) have not been investigated with autistic youth despite high parent-child rating discrepancies. In the…

In response to the widespread youth mental health crisis, some kindergarten-through-12th-grade (K-12) schools have begun employing artificial intelligence (AI)--based tools to help identify students at risk for suicide and self-harm. The adoption of AI and other types of educational technology to partially address student mental health needs has…

Objective: Combine National Collegiate Health Assessment (NCHA) measures indicating LGBTQ + membership into a single variable in order to analyze health responses of this group as compared to their cisgender, heterosexual (cis-het) peers. Participants: Students at a liberal arts university who completed the Spring 2019 NCHA-II study (n = 1107).…

To examine the risk for premature mortality and intentional self-harm in autism spectrum disorders (ASD). Based on a national birth cohort. Children born in 1987-2005, diagnosed with ASD by 2007 (n = 4695) were matched with four non-ASD subjects (n = 18,450) and followed until 2015 for mortality and intentional self-harm. The risk among ASD…

Objective: We examined whether meaningful subgroups of self-injurious behaviors (SIBs) would emerge within a pool of first-year college students already deemed at elevated risk. Participants: First-year undergraduates (N = 1,068) recruited in 2015-2018 Fall terms. Methods: Past-year nonsuicidal self-injury (NSSI) frequency, past-year number of…

This study builds on existing literature on autism spectrum disorder (autism) and sexual and gender minority (SGM) identities and is the first to examine self-declared frequency rates, associated functional impairments, and treatment engagement levels for sexual minority (SM) and non-SM populations with and without autism cross-sectionally via a…

Objective: Previous studies have linked ADHD with self-harm, but the processes underlying this association are not fully understood. This research aims to investigate the role of sleep disturbances as a potential pathway between ADHD diagnosis and self-harm behaviors. Materials and Methods: The study included 90 youth aged between 11 and 18 years,…
