Behavioral correlates to happiness (i.e., indices of happiness) have been used as means of measuring happiness in individuals with developmental disabilities. However, research has not yet evaluated the possibility that indices of happiness/unhappiness (IHUs) may signal the presence of a setting event that could affect other behaviors. The purpose…

Little is known about the attributional patterns of caregivers of autistic children, particularly in relation to caregivers of children with other developmental or behavioral disorders. This study examined differences in caregiver attributions of child behavior between three groups: toddlers with (1) Autism spectrum disorder (ASD) or ASD concerns;…

Individuals with autism spectrum disorder and other developmental disabilities (ASD/DD) may engage in socially inappropriate masturbation that puts them or others at risk for harm. This may lead professionals, parents, and other stakeholders to intervene in ways that suppress safe, socially appropriate, and gratifying masturbation. Single case…

Objective: This study was conducted to explore the effect of motor coordination on repetitive behaviors in children with Autism Spectrum Disorder (ASD) aged 5-15 years. Methods: The study employed the causal-comparative design, one of the correlational survey designs. The study was carried out with data obtained from parents of 241 children with…

Children with neurodevelopmental disorders often have social-emotional and behavioural difficulties. The present study explored these difficulties in children (n = 50, aged 6-10 years) with autism spectrum disorder, attention-deficit/hyperactivity disorder and developmental language disorder. Parents, teachers and therapists evaluated children's…

Children and adults with developmental disabilities often experience oral health problems such as excessive plaque accumulation and dental restorations related to caries. Researchers have examined the efficacy of a variety of behavioral intervention packages to teach preventative strategies (brushing, flossing) and to decrease challenging…

This 10-year study followed 134 caregivers of young adults with autism and intellectual disability, examining the effects of caregivers' coping strategies, sociodemographic features, and young adult symptomatology on caregiver well-being and depression. Lower caregiver education and higher young adult externalizing behaviors predicted lower…

The prevalence of challenging behavior, such as aggression, self-injurious behavior, tantrums, and noncompliance with everyday expectations among young children with intellectual and developmental disability (IDD), is higher than the prevalence of challenging behavior for children without disabilities. Without appropriate intervention, challenging…

Functional communication training (FCT) is a well-established, evidence-based practice used to address challenging behavior among individuals across settings, ages, and disability categories. However, the research is limited on the implementation of FCT in inclusive school settings for students with intellectual and developmental disabilities. The…

Functional behavior assessment (FBA) is an integral component of treatment development for students with intellectual and developmental disabilities. The continuum of FBA methods includes indirect, direct, and functional analysis assessment methods. However, there is not a standard for the best approach to the FBA process. This evaluation compared…

Objective: To determine whether functional self-care skills and presence of behavior problems in youth with developmental disabilities are associated with parents planning for the youth's transition to adulthood. Methods: This multi-site study consisted of 167 parents of youth aged 10-22 years with autism spectrum disorder, ADHD and/or other…

Despite the early onset of challenging behaviors, there is a lack of research investigating the function of challenging behavior in toddlers with autism spectrum disorder (ASD) and developmental disabilities (DDs). The current study evaluated group differences in the frequency and severity of five functions of challenging behavior (i.e.,…

To date, most studies seeking to explore the impact of COVID-19 school closures on student outcomes have focused on cognitive/academic losses. This study explores changes in adaptive behaviors experienced by children and youth with autism spectrum disorders or other developmental disabilities when in-person, one-to-one behavior training was…

Background: Limited data exist on problematic sexual behaviour (PSB) in youth with developmental disabilities in South Korea. Method: Sixty-one parents of children with intellectual disabilities or autism spectrum disorder (aged 13-30) reported children's PSB and emotional, behavioural, cognitive, and interpersonal factors. The frequency of PSB in…

Food selectivity affects up to 72% and 45% of individuals with and without disabilities, respectively, and there is a need for interventions that rely on positive, unrestrictive strategies. We evaluated an assessment and treatment package for food selectivity for young children with developmental disabilities that prioritized caregiver…
