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…

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…

Parents of children with autism spectrum disorder (ASD) often experience elevated levels of caregiver strain (CGS). Few studies have examined the relationship between core ASD symptoms and each facet of CGS: objective, subjective internalized, and subjective externalized strain. The predictive effect of core and associated features of ASD on CGS…

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and…

The purpose is to test the applicability of the Positive and Negative Affect Scale (PANAS) to Chinese children with intellectual disabilities. The study was done by distributing the questionnaire to the parents through teachers online. Asked the parents to fill out the scale based on their observations of their children's daily life. The…

Echolalia has been described as the repetition of words, phrases, songs or other more elaborate dialogues uttered by another person, which may be immediate or delayed (International Classification of Diseases, 11th Revision; "Diagnostic and Statistical Manual of Mental Disorders", 5th ed.). Some classify echolalia as a communication…

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…

Mental health conditions are more prevalent in autistic people than non-autistic people. The Strengths and Difficulties Questionnaire is a commonly used screening tool for emotional and behavioural difficulties in autistic children and adolescents. However, few studies have assessed the psychometric properties of the Strengths and Difficulties…

Paternal incarceration is an important predictor of teen delinquency, but the factors that may explain this relationship--such as early child problem behaviors and level of father engagement--have not been adequately explored. The current longitudinal study examined paternal history of incarceration as a predictor of teen self-reported delinquency…

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and…

Behaviour problems in early childhood have a lasting impact on cognitive development and education attainment in later adolescence and into adulthood. Here we address the relationship conduct and hyperactivity problems at school entrance, and vocabulary acquisition in adolescence. We compare performance in identical assessments across two…

There is increasing concern regarding additional psychiatric problems that co-occur with Autism Spectrum Disorder (ASD), as reflected in recent changes to diagnostic schemes. However, there remains little research with population-based samples across childhood. We report on additional problems, as measured by the Strengths and Difficulties…

Individuals diagnosed with autism spectrum disorder (ASD) are more likely to have suicidal thoughts and behaviors. However, little research delineates the temporal and mechanistic associations between potential risk factors and suicidality in autistic individuals. We assessed 129 autistic and 121 age-matched and sex-assigned-at-birth-matched…

The Nisonger Child Behavior Rating Form (NCBRF) was developed to specifically screen psychopathology and problem behavior in children and adolescents with IDD. This study aimed to update the NCBRF to the "Diagnostic and Statistical Manual of Mental Disorders, 5th Edition" (DSM-5) and screen for the most prevalent psychopathologies that…
