Background: Adults with intellectual disability (ID) are at high risk of exhibiting challenging behaviors, especially those with autism spectrum disorder (ASD). There are clinical and transdiagnostic variables that are largely related to the existence of these behaviors, and it is necessary to know the particularities of their role in people with…

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…

We analyzed the Healthcare Cost and Utilization State Emergency Department (ED) Databases and State Inpatient Databases for all individuals who were 2 years of age or older with at least one ED visit from 2011 to 2016 in New York to estimate the association between suicide and non-fatal injury-related ED visits and autism spectrum disorder (ASD).…

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…

Autism spectrum disorder (ASD) is an etiologically heterogeneous neurodevelopmental condition that eludes a single explanation or cure. Epidemiological studies reveal risk factors, relevant comorbidities, and behavioral correlates to reach a better understanding of ASD. To contribute such data from an understudied ASD population, this paper…

Parents of children with ASD who had attended an Australian emergency department (ED; n = 421) completed a questionnaire relating to their experiences in the ED, including (1) child's reason for presentation and existing comorbidities, (2) quality of care during the visit (3) child's behaviour during visit, e.g. sensory responses to the ED…

Objective: This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods: A retrospective chart review studied characteristics of severe…

Psychiatric disorders are common in youth with intellectual and developmental disabilities. This is a vulnerable group of children whose behavioural problems often have more complicated care needs than other children, which can place a great deal of stress on their families. However, the association of family mental health issues, level of…

Introduction: Anxiety disorders are highly prevalent in individuals with autism spectrum disorder (ASD), but knowledge is limited regarding identification and treatment of these disorders in individuals with ASD and more severe levels of intellectual disability (ID). The current case study aims to explore and describe the inpatient, psychiatric…

Background: Epilepsy and challenging behaviour are both highly prevalent in the intellectual disability (ID) population and it is thus crucial to understand any possible associations between the two. Method: PsycINFO, MEDLINE, Embase, CINAHL and Web of Science were searched for quantitative data about epilepsy and any forms of challenging…

Background: The aim was to investigate the aggressive behavior of young people in specialized institutions with intellectual disability (ID) with or without autism spectrum disorder (ASD). Method: Data on 305 institutionalized young people were collected using two aggression scales, the 'Children's Scale of Hostility and Aggression:…

Self-injurious behavior (SIB) occurs in up to 50% of individuals with autism. As one of the most serious conditions in individuals with developmental disabilities, SIB affects the individual and his or her family in multiple contexts. A systematic analysis of factors most commonly associated with SIB could inform the development of individualized…

Objective: This study examined psychosocial distress and substance use in young adults with asthma (A), obesity (O), comorbid asthma and obesity (AO), or neither (controls). Participants: Eight hundred eighty-one young adults were included in the A, O, AO, or control group. Methods: ANCOVA and logistic regression analyses were performed to compare…

Although autism spectrum disorder (ASD) is associated with significant mental health concerns, little is known about suicidality, particularly among youth. To address this critical gap in the literature, the current study examined the predictive validity of (1) demographics, (2) core autism symptoms, (3) cognitive abilities and adaptive behavior,…

Adolescent risk-taking can potentially result in serious individual and societal consequences. Previous research demonstrates that emotional and behavioral problems, particularly externalizing behaviors, are significantly associated with an array of risky behaviors such as substance use, sexual behavior, injury, and violence. However, the…
