Operational definitions have a significant history in applied behavior analysis. The practice's importance stems from the role operational definitions play in detecting an event, human thought, or action. While operationalizing target behaviors has enjoyed widespread practice, some concerns have recently arisen with translation validity and…

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…

Purpose: To investigate serum levels of VEGF, IGF-1 and FGF-2, and relationships with several clinical characteristics in children and adolescents with autism spectrum disorder (ASD) with and without bipolar disorder (BD). Method: 40 subjects with ASD + BD as study group, and 40 subjects with ASD as control group were included. Serum levels of…

Substantial efforts have been dedicated to understanding, assessing, and managing suicide risk in youth broadly. However, little attention has been focused specifically on autistic youth and youth with intellectual disability. Because emergency departments are an essential point of suicide-related care, we used the National Emergency Department…

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,…

Autistic people experience a higher prevalence of self-harming behaviours than do the general population. Self-harm remains a stigmatised topic, and until recently, self-harming behaviours in autism were considered to be limited to self-injurious behaviours experienced by intellectually impaired autistic children and not to be experienced by…

Rates of self-injurious thoughts and behaviors are elevated among autistic youth, yet research is limited to caregiver report or single-item questionnaires. Investigation of specific suicidal thoughts, triggers, and disclosure is needed to improve risk assessment and interventions. The current study characterized self-injurious thoughts and…

Autistic people are at greater risk of self-harm than non-autistic people, yet no tools exist specifically for assessing self-harm in this population. We therefore conducted two focus groups with autistic adults (n = 5) and professionals (n = 4) to examine their perspectives on three existing self-harm assessment tools (Non-Suicidal Self-Injury --…

Background: Understanding the operant function of self-injurious behavior in autistic individuals is imperative to understanding its etiology and designing effective prevention strategies. Methods: We conducted a postal survey of residential care facilities including two functional assessment tools: QABF and IfES. Questionnaires for N = 178…

This was an exploratory cross-sectional study comparing 45 children with ASD to 24 typically developing drug-naïve controls, group-matched on age, sex, and body mass index. Objective data was obtained using the following: an ambulatory circadian monitoring device; saliva samples to determine dim light melatonin onset (DLMO): and three…

Purpose: Emergency department (ED) visits for suicidal ideation and self-harm are more prevalent in autistic than non-autistic youth. However, providers are typically offered insufficient guidance for addressing suicide risk in autistic youth, likely impacting confidence and care. Methods: In this pilot study, we conducted semi-structured…

Given that autistic children are hospitalized at higher rates than neurotypical peers, it is important to understand the autism-specific preparedness of healthcare providers. Certified Child Life Specialists (CCLSs) play a crucial role in pediatric hospitalizations by providing socioemotional support and coping strategies. The present study…

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).…

Communication deficits are one of the main characteristics of autism spectrum disorder (ASD). Self-injurious behavior (SIB) in individuals with ASDs often occurs due to the individuals' lack of social-communicative abilities to express what they want (e.g., attention; access to tangible items; help). Many researchers have successfully used…

Purpose: Several studies have reported on the intersection of autism and gender incongruence (GI) in clinical populations. This study aims to investigate autistic characteristics and registered autism spectrum diagnoses (ASD) in a clinical cohort of 83 adolescents referred to the National Gender Team for Children and Adolescents in Norway during…
