Attention Deficit/Hyperactivity Disorders (ADHD) are typically diagnosed in terms of Inattention Problems (INP) and Hyperactivity/Impulsivity Problems (HIP). However, considerable evidence supports an additional set of attentional problems designated as Sluggish Cognitive Tempo (SCT), characterized by lethargy, daydreaming, and confusion. To test relations between genetic and environmental influences on SCT, INP, and HIP, Moruzzi et al…. Read more »

Research on bullying has revealed high prevalence rates and adverse consequences in many countries. However, less is known about protective factors that might reduce adverse effects of bullying on children’s behavioral and emotional problems. To test effects of bullying and of protective factors, Bowes et al. (2010) assessed 1,116 twin pairs with the CBCL and… Read more »

Research has revealed enlarged error-related negativity (ERN) in people with OCD. ERN is a negative deflection of an event-related potential that peaks within 100 milliseconds after an incorrect response. Enlarged ENTs apparently reflect overactive performance monitoring involving an alarm signal to increase cognitive control. Hanna et al. (2016) tested associations between the ERN and CBCL… Read more »

A “Dysregulation Profile” defined by elevated scores on the ASEBA Anxious/Depressed, Attention Problems, and Aggressive Behavior syndromes has been identified in multiple studies. Deutz et al. (2016) analyzed mothers’ and fathers’ CBCL ratings and teachers’ TRF ratings of 697 children living in Flanders, the Dutch-speaking region of Belgium, at a mean age of 7.9 years…. Read more »

Millions of children and youths around the world have become refugees from war, persecution, and ethnic cleansing. Many of the young refugees have been accepted for resettlement in host countries. To optimize care for young refugees, it is important to evaluate their functioning in host countries and to identify factors associated with good versus poor… Read more »

The Adult Self-Report (ASR) assesses adaptive functioning, personal strengths, and diverse behavioral, emotional, social, and thought problems and substance use on the basis of self-reports by 18-59-year-olds. The parallel Adult Behavior Checklist (ABCL) assesses most of the same aspects of functioning on the basis of reports by collaterals (spouse, partner, family member, friend, therapist, etc.)… Read more »

Although events such as the World Trade Center (WTC) attacks are apt to be traumatic for people of all ages, research has shown that preschoolers who had experienced other traumatic events prior to the WTC attacks were more likely to develop behavioral/emotional problems than children exposed only to the WTC events (Chemtob et al., 2008,… Read more »

Immaturity has been implicated as a possible component of ADHD. To test the possible role of immaturity, Brikell et al. (2016) obtained Swedish parents’ ratings of 1,302 pairs of 8-9-year-old twins’ immaturity relative to average children of the same age. The ratings of relative immaturity (RI) were analyzed in relation to parents’ CBCL ratings of… Read more »

Of the adverse conditions faced by children, one of the most appalling is the conscription of tens of thousands of children to serve in armed conflicts. In order to help former child soldiers, it is necessary to identify their particular problems and strengths, plus associated risk and protective factors. Although outcomes of very adverse experiences… Read more »

According to DSM-IV, there are three types of Attention Deficit Hyperactivity Disorder (ADHD): Primarily Inattentive (PI), Hyperactive/Impulsive (H/I), and Combined type (CT). The DSM criteria specify that 6 out of 9 PI symptoms and/or 6 out of 9 H/I symptoms are required to qualify for a diagnosis of ADHD. The fact that any 6 symptoms… Read more »

Recent studies have suggested that a general factor underlies associations among diverse aspects of psychopathology. Newmann et al. (2016) tested the presence and heritability of a general psychopathology factor in parent-, teacher-, and self-reports for 2,115 Dutch 6-8-year-olds participating in the longitudinal Generation R (R = Rotterdam) study. The use of parent-, teacher-, and self-reports… Read more »

ADHD is commonly assumed to affect far more boys than girls. However, diagnostic criteria for ADHD may be less able to detect attention problems among girls because some ADHD criteria reflect characteristics that are more annoyingly conspicuous and have higher population base rates among boys than girls. To learn more about ADHD in girls, Stephen… Read more »
