There is substantial comorbidity between autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD), and there are well-documented executive functioning (EF) deficits in both populations. An important question concerns whether EF deficits in children with ASD are related to severity of ASD, ADHD, or both. We examined ADHD…

Individuals with ADHD report diminished emotion regulation capacities and adversity in childhood detrimentally affects emotion regulation development; however, how positive childhood experiences (PCEs) and whether and how social support are related to PCEs and emotion regulation for those with ADHD is unknown. Objective: To identify direct and…

Background: Many children with attention-deficit/hyperactivity disorder (ADHD) demonstrate impairment in social skills. However, ADHD rarely occurs in isolation, with approximately one-third of children with ADHD having one additional disorder, and another third having two or three comorbidities. Few studies have considered the global and specific…

This research aims to develop an instrument for the evaluation of impulsivity traits in children and to examine the psychometric features of the developed scale. The process of developing the scale involved three main phases: namely, item generation, evaluation of content validity, and analysis of psychometric properties. The study sample…

Objective: The study aims to examine family functionality, emotion regulation difficulties, preference for loneliness, social exclusion, internalizing and externalizing disorders, and executive functions in children with Attention Deficit Hyperactivity Disorder (ADHD) and Cognitive Disengagement Syndrome (CDS) and compare with ADHD, and ADHD+…

Objective: The QbTest that combines a continuous performance task (CPT) with a motion-tracking system may help identify attention deficit hyperactivity disorder (ADHD). This study examined the structure and diagnostic ability of the QbTest in children and adolescents. Method: Retrospective data from 1,274 children and adolescents were analyzed.…

Commonly proven abnormalities in the structure and functioning of the prefrontal cortex (PFC) are related to cognitive deficits in children with ADHD. The purpose of the randomized controlled study was to assess the efficacy of intervention using hemoencephalographic biofeedback (HEG BFB) in PFC in ADHD and neurotypical children. The final cohort…

Understanding and regulating emotions influence children's friendships. Children with Attention Deficit/Hyperactivity Disorder (ADHD) and Specific Learning Disorder (SLD) have difficulties in understanding emotions and in controlling themselves. ?he present study examines how children's friendships and their quality may be affected by emotion…

Research suggests that a childhood diagnosis of Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD) is associated with poorer teacher-child relationship quality and higher rates of externalising behaviours. It is proposed that the socio-emotional problems experienced by those children with ASD and/or ADHD lead to poor…

We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5-12 years. Children (n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child…

Non-pharmacological interventions for attention-deficit/hyperactivity disorder are useful treatments, but it is unclear how effective school-based interventions are for a range of outcomes and which features of interventions are most effective. This paper systematically reviews randomised controlled trial evidence of the effectiveness of…

ADHD is a disability characterised by hyperactivity, impulsivity and difficulties maintaining attention. Despite extensive research on ADHD, the effects of existing treatments are moderate and inconsistent. Knowledge regarding children's and adolescents' everyday experiences of Attention Deficit Hyperactivity Disorder (ADHD) and their…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…

Background: The development of mindfulness parenting programs in recent years offers a promising direction for targeting parental emotional dysregulation in families of children with attention deficit hyperactivity disorder (ADHD). Nevertheless, research on the effectiveness of mindfulness parenting programs is limited, and little is known about…

Autism spectrum disorder (ASD) and Attention-deficit/hyperactivity disorder (ADHD) are often comorbid. The purpose of this study is to explore the relationships between ASD and ADHD symptoms by applying causal modeling. We used a large phenotypic data set of 417 children with ASD and/or ADHD, 562 affected and unaffected siblings, and 414 controls,…
