The present meta-analysis integrates research from 1,435 studies on associations of parenting dimensions and styles with externalizing symptoms in children and adolescents. Parental warmth, behavioral control, autonomy granting, and an authoritative parenting style showed very small to small negative concurrent and longitudinal associations with…

Within the past few decades, scholars, lawmakers, and educators have increased attention to a specific type of aggressive behavior known as bullying. While bullying is like peer aggression and harassment, in that they all pertain to negative aggressive actions, there are important distinctions among these three forms of behavior. The key features…

Background: Juvenile offenders with intellectual disability (ID) have been largely ignored in the literature of risk assessment, while they are overrepresented in the criminal justice system, and ID is a risk factor for juvenile delinquency and recidivism. The aim of this study was to examine whether there are differences between juvenile…

As the "Behavioral Assessment System for Children, Second Edition" ("BASC-2") is often used to aid in diagnosis it is important to discern how children and adolescents with Autism Spectrum Disorder (ASD) score on the "BASC-2" compared to typically developing controls. This study compared scores of typically developing…

In 2006, the administration of a state-run, secure juvenile correctional facility initiated an attempt to transform its institutional culture using a strength-based approach to assessment and case planning. This resulted in a rapid improvement in institutional climate. The current study revisits this setting several years later to see if those…

Background: A functional polymorphism in the promoter region of the monoamine oxidizing gene "monoamine oxidase A" ("MAOA") has been associated with behavioral sensitivity to adverse environmental conditions in multiple studies (e.g., Caspi et al. 2002; Kim-Cohen et al., 2006). The present study investigates the effects of…

Individuals with intellectual and developmental disabilities are often prescribed psychotropic medication to treat behaviors such as aggression and self-injury. Evaluation of these medications is often based on caregiver report or changes in frequency of behavior. The purpose of this research was to characterize the rate and function of problem…

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…

Recent evidence suggests that 2 largely orthogonal dimensions underpin the latent construct assessed by the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996): Fearless Dominance (PPI-I) and Impulsive Antisociality (PPI-II). Relatively few data exist on the correlates of these 2 dimensions in offender samples, however. The…

Background: The "Questions About Behavioral Function" (QABF) correctly identifies maintaining variables of challenging behaviour. However, for adults who have a long history of challenging behaviours, identifying one clear function of the maladaptive behaviour is difficult. Additionally, the person may develop multiple functions of their…

The validity of using rapidly alternating multiple schedules (RAMS) as a method for assessing and treating aggression was demonstrated by using the naturally occurring reinforcers identified in the RAMS to develop treatments that were experimentally tested. All treatments using the reinforcers identified in the RAMS were effective. Possible uses…

A common covarying group of behaviors with ASD are self-injury, aggression, noncompliance, and stereotypies. These problems and related challenging behaviors are problematic in that they are physically dangerous and can impede learning and access to normal activities. Additionally, they require a considerable amount of resources, and compound the…

Exploratory factor analysis (EFA) is a frequently used multivariate analysis technique in statistics. Jennrich and Sampson (1966) solved a significant EFA factor loading matrix rotation problem by deriving the direct Quartimin rotation. Jennrich was also the first to develop standard errors for rotated solutions, although these have still not made…

In planning interventions it is essential to understand how adverse risk factors in early childhood are associated with child mental health problems, whether some types of problems can be better explained by the specific risk factors, and whether early risk factors are differently related to different types of child behavior problems. A community…

Background: Reliable measures of aggressive challenging behaviour are required if interventions aimed at reducing this behaviour among people with intellectual disability (ID) are to be formally evaluated. The present authors examined the reliability of the Modified Overt Aggression Scale (MOAS), an instrument not yet formally tested in those with…
