Competing hypotheses for explaining the role of anxiety in the relation between attention-deficit/hyperactivity disorder (ADHD) symptoms and childhood aggression were evaluated. Two studies tested whether anxiety exacerbated, attenuated, or had no effect on the relation between ADHD and aggression subtypes among psychiatrically hospitalized…

In this study a homophily selection hypothesis was tested against a default selection hypothesis, to answer whether preferred and realized friendships of highly aggressive boys differed. In a large peer-nomination sample, we assessed who highly overt aggressive, low prosocial boys (n = 181) nominated as friends (preferred friendships) and who…

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…

Researchers have recognized the importance of developing an accurate classification system for externalizing disorders, though much of this work has been framed by a priori preferences for categorical vs. dimensional constructs. Newer statistical technologies now allow categorical and dimensional models of psychopathology to be compared…

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…

Objective: The authors conducted a meta-analysis of empirical studies investigating associations between indices of posttraumatic stress disorder (PTSD) and intimate relationship problems to empirically synthesize this literature. Method: A literature search using PsycINFO, Medline, Published International Literature on Traumatic Stress (PILOTS),…

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: Psychiatric evaluation of adults with intellectual disability (ID) remains complex because of limitations in verbal abilities, atypical clinical presentation and challenging behaviour. This study examines the clinical presentation of adults with depression compared with bipolar disorder, anxiety disorders and non-psychiatric control…

The authors' goals in the study were to investigate the possible gains made by including multiple assessments of status in the prediction of change in psychosocial adjustment and to compare the effectiveness of continuous and categorical measures of peer status in predicting adjustment. The authors obtained continuous and categorical measures of…

Overt-relational and reactive-proactive subtypes of aggression have demonstrated a reliable network of relationships with social-adjustment variables and these variables have been shown to be effective predictors of future behavior problems and social maladjustment. In this study, the two measures representing these classification systems were…

The "Handbook of Research on Electronic Surveys and Measurements" is the comprehensive reference source for innovative knowledge on electronic surveys. This commanding handbook of research provides complete coverage of the challenges associated with the use of the Internet to develop online surveys, administer Web-based instruments, and conduct…
