Stereotypy or automatically occurring behaviors, as commonly seen in children with autism spectrum disorder, can be divided into three main categories: self-injury, stereotypy, and aggressive behaviors. Researchers have suggested different intervention approaches to treat stereotypy, such as redirecting or replacing undesired action. This Delphi…

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…

Restricted interests and repetitive behaviors (RRBs) are core symptoms of autism spectrum disorder (ASD), and commonly occur in attention-deficit/hyperactivity disorder (ADHD). Little is known about how RRBs manifest in ADHD. We quantified and compared factor structures of RRBs in children with ASD (n = 634) or ADHD (n = 448), and related factors…

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…

Objectives: Researchers examined associations between specific forms of emotion dysregulation and numerous behavioral manifestations of impulsivity (i.e., problematic alcohol use, drug use, risky sexual activity, binge eating, non-suicidal self-injury). Participants: Participants were 238 undergraduate students (69% female). Method: Emotion…

Using a dataset involving 415 individuals with irritability, aggression, agitation and self-injury (IAAS) behaviors from the fragile X syndrome (FXS) FORWARD database, we describe the psychopharmacologic management of IAAS and features of the population of persons with FXS treated with drug therapy for IAAS. Among those with FXS exhibiting IAAS,…

Background: Challenging behaviour, such as self-injury and physical aggression, is an issue of concern regarding a high proportion of individuals with fragile X syndrome. The aim of this review was to provide a comprehensive overview of the topographies and operant functions of challenging behaviours within the syndrome. Method: Five electronic…

Previous research is not conclusive in detailing the prevalence of challenging behaviour and its correlates in children with intellectual disabilities in school settings in particular. In the current study, an amended version of the Behaviour Problems Inventory -- Short Form was used to collect data from a sample of 321 students in a special…

Background: Behaviour problems are most common in people with intellectual disabilities. Nature of behaviour problems can vary depending upon the age, sex and intellectual level (IQ). Objectives: This study examined the distribution of behaviour problems across intellectual disability categories and their association with IQ age and sex in…

Introduction: Children and young adults with Down syndrome can demonstrate increased behavior problems compared to their typically developing peers through childhood and adolescence. Though current tools measure behavior problems in persons with intellectual disabilities, they do not capture all the behavioral problems that can occur in…

Results from the 2009 "National College Health Assessment" were analyzed by gender and sexual orientation for college students' nonmedical use of prescription drugs. Male and female students identified as having a minority sexual orientation (gay or bisexual) were significantly more likely to use nonmedical prescription drugs than…

Patterns of nonsuicidal self-injury (NSSI) and their association with other psychological difficulties were studied in a community sample of young Swedish adolescents, by a two-wave longitudinal design with a 1-year interval. Hierarchical cluster analysis at T1 identified eight NSSI subgroups in each gender, of which five were clearly replicated…

Before the 1990s, research on the early identification and prevention of severe behavior disorders (SBDs), such as aggression, self-injury, and stereotyped behavior, among young children with intellectual and developmental disabilities (IDD), was mostly done with children 3 years or older. More recent work suggests that signs of SBDs may occur as…

Background: Recurrent respiratory infections (RRI) are among most common diseases in school-aged children. Little is known about possible associations between RRI and children psychological well-being. Aim: To study possible associations between RRI in junior school pupils and their emotional/behavioural characteristics. Methods: The RRI group…

Runaway and homeless youth often have a constellation of background behavioral, emotional, and familial problems that contribute to stress and maladaptive behaviors, which, in turn, can lead to self-harming and suicidal behaviors. The current study examined the roles of stress and maladaptive behaviors as mediators between demographic and…
