It was not known what school staff identifies as student behavioral concerns in rural, low-income elementary schools, what they attribute as the cause of these behaviors, and how this attribution may affect their response to such behavior. This qualitative case study explored the experiences of school staff members at a low-income elementary…

Background: It is mandatory for staff in Swedish community services for people with intellectual disabilities to report incidents of error or malpractice. Aim The aim is to study if incident reports contribute to developing quality in services for people with intellectual disabilities who present with challenging behaviours. Method: 159 reports on…

Background: The aim was to investigate the aggressive behavior of young people in specialized institutions with intellectual disability (ID) with or without autism spectrum disorder (ASD). Method: Data on 305 institutionalized young people were collected using two aggression scales, the 'Children's Scale of Hostility and Aggression:…

Technologically mediated contexts are social arenas in which adolescents can be both perpetrators and victims of aggression. Yet, there remains little understanding of the developmental etiology of cyber aggression, itself, as experienced by either perpetrators or victims. The current study examines 3-year latent within-person trajectories of…

Behaviour problems in young children are fairly common. It has been suggested that approximately 5-14% of preschool children exhibit problem behaviour. There are many reasons for behaviour problems in preschool-aged period children. Researches reveal that link between victimisation and individual differences. However, but still, we do not know the…

Investigating heterogeneity in antisocial behavior early in life is essential for understanding the etiology, development, prognosis, and treatment of these problems. Data from the longitudinal National Institute of Child Health and Development (NICHD) study of Early Child Care were used to identify homogeneous groups of young antisocial children…

Background: Behavioural interventions conceptualise self-injurious behaviour (SIB) as developing from early repetitive behaviours through acquisition of homeostatic functions in regulating stimulation and subsequent shaping into SIB through socially mediated or automatic operant reinforcement. Despite high success rates, such interventions rarely…

This study considers school violence. It was investigated in secondary schools in the governorate of Mafraq. The aim is to identify the forms and causes of the phenomenon; hence to come out with the preventive and remedial measures, accordingly. The study was conducted in one of the secondary schools selected randomly in the city of Mafraq in the…

Williams-Beuren syndrome (WBS) is a genetically determined neurodevelopmental disorder caused by a heterozygous deletion of 26-28 genes on chromosome band 7q11.23. During the past few years, researchers and clinicians have significantly contributed to define the phenotype of the syndrome, including its cognitive and behavioral aspects. However, it…

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe…

Although fragile X syndrome (FXS) is a single gene disorder with a well-described phenotype, it is not known why some individuals develop more significant maladaptive behaviors such as aggression or autistic symptoms. Here, we studied two candidate genes known to affect mood and aggression, the serotonin transporter (5-HTTLPR) and monoamine…

Background: Children with Autistic Disorder (AD) evidence more co-occurring maladaptive behaviours than their typically developing peers and peers with intellectual disability because of other aetiologies. The present study investigated the prevalence of Clinically Significant maladaptive behaviours during early childhood and identified at-risk…

A portion of the paper was presented at the 1969 International Congress of Psychology in London. (Author)

Objective: Prenatal smoking is robustly associated with increased risk of conduct problems in offspring. Observational studies that provide detailed phenotypic description are critical for generating testable hypotheses about underlying processes through which the effects of prenatal smoking may operate. To this end, we use a developmental…

University women (N=277) completed questionnaires providing retrospective reports of childhood abuse. History of psychological abuse was uniquely associated with low self-esteem, physical abuse was linked to aggression toward others, sexual abuse was related to maladaptive sexual behavior, and physical and emotional abuse together resulted in…
