Methods: Data on challenging behaviour were collected for 225 students in one school over four annual time points and a range of potential risk…

This study aimed at analyzing the differences in challenging behaviors between adults with intellectual disability and ASD and those who only had intellectual disability, as well as to explore associations between transdiagnostic and clinical variables to these differences. Therapists and educators of 163 adults with intellectual disability (83…

Restricted or repetitive behavior (RRB) is common for individuals with visual impairment (VI), autism spectrum disorder (ASD), and intellectual disability.

Cornelia de Lange syndrome (CdLS) is associated with repetitive and self-injurious behaviors (RBs, SIB). Evaluating children with CdLS, this study: (1) characterizes the spectrum of RBs; (2) characterizes the impact and severity of RBs including SIB; (3) describes how age and adaptive functioning relate to RBs including SIB. Fifty children…

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,…
