Deficits in Working Memory (WM) are related to symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD). In children with ADHD visuospatial WM is most impaired. WM is composed of Short-Term Memory (STM) and a Central Executive (CE). Therefore, deficits in either or both STM and the CE may account for WM impairments in children with ADHD. WM-comp...

Deficits in working memory (WM) and reinforcement sensitivity are thought to give rise to symptoms in the combined (ADHD-C) and inattentive subtype (ADHD-I) of ADHD. Children with ADHD are especially impaired on visuospatial WM, which is composed of short-term memory (STM) and a central executive. Although deficits in visuospatial WM and reinforcem...

Executive functions (EFs) training interventions aimed at ADHD-symptom reduction have yielded mixed results. Generally, these interventions focus on training a single cognitive domain (e.g., working memory [WM], inhibition, or cognitive-flexibility). However, evidence suggests that most children with ADHD show deficits on multiple EFs, and that the...

Objective: Executive functioning (EF) training-interventions aimed at ADHD-symptom reduction have limited results. However, EF-training might only be effective for children with relatively poor EF capacity. This randomized double-blind placebo-controlled study examined if pre-training EF capacity moderates the outcome of an EF-training intervention...

Abstract Neurodevelopmental conditions and associated disabilities such as autism spectrum disorders (ASD), attention deficit hyperactivity disorder (ADHD), and learning disorders (LD) become apparent in childhood. These conditions often come with difficulties in cognitive functions, e.g., executive functions (EFs). Targeting EFs in an intervention...

A new perspective on ADHD; The role of executive functioning and motivation S. Dovis, S. Van der Oord, R.W. Wiers & P.J.M. Prins In this 14 page Dutch article, focused mainly on clinicians, parents and teachers, we explain how deficits in executive functioning (EF) and motivation can result in ADHD symptoms. Further, we discuss reinforcement effe...

Interventions in School: learning problems Schools leren bij kinderen kan problematisch verlopen door verschillende oorzaken, zoals dyslexie, dyscalculie, cognitieve beperkingen of juist hoogbegaafdheid. Leerproblemen kunnen ook worden veroorzaakt door een non-verbale leerstoornis of door tekorten in de executieve functies, zoals vaak het geval is...

Dutch translation of the Childhood Executive Functioning Inventory (CHEXI) for Parents and Teachers. The CHEXI (including the Dutch translation) is freely available at www.chexi.se. The CHEXI focuses on working memory, inhibition, planning and regulation and seems more suited for children with ADHD than the BRIEF (and it has less items).

Both cognitive and motivational deficits are thought to give rise to the problems in the combined (ADHD-C) and inattentive subtype (ADHD-I) of attention-deficit hyperactivity disorder (ADHD). In both subtypes one of the most prominent cognitive weaknesses appears to be in visuospatial working memory (WM), which is composed of short-term memory (STM...

In the area of childhood attention-deficit hyperactivity disorder, there is an urgent need for new, innovative, and child-focused treatments. A computerized executive functioning training with game elements aimed at en-hancing self-control was developed. The first results are promising, and the next steps involve replication with larger samples, ev...

Visual-spatial Working Memory (WM) is the most impaired executive function in children with Attention-Deficit/Hyperactivity Disorder (ADHD). Some suggest that deficits in executive functioning are caused by motivational deficits. However, there are no studies that investigate the effects of motivation on the visual-spatial WM of children with- and...

Obesitas bij kinderen is de afgelopen decennia sterk toegenomen. Er is een aantal redenen om te interveniëren bij obesitas op de kinderleeftijd. Cardiovasculaire risicofactoren komen bij ernstige obese kinderen veel vaker voor dan bij kinderen zonder gewichtsproblemen en obesitas op de kinderleeftijd vergroot het risico op cardiovasculaire morbidit...

This study examined the benefits of adding game elements to standard computerized working memory (WM) training. Specifically, it examined whether game elements would enhance motivation and training performance of children with ADHD, and whether it would improve training efficacy. A total of 51 children with ADHD aged between 7 and 12 years were ran...

Er is grote behoefte aan nieuwe behandelmethodieken voor kinderen met ADHD bij wie medicatie niet of slechts gedeeltelijk werkt of bij wie psychosociale interventies nog ruimte voor verbetering laten. Er is bovendien naast de beschikbare methoden voor de ouders en leerkrachten van de kinderen met ADHD grote behoefte aan een methodiek die op het kin...

Question
Hi,
We are doing moderation analyses via Hayes Process tool (model 1), and are wondering about how to exactly interpret the “R-square increase due to interaction” output (parameter “R2-chng”). We know that it is part of the R-squared parameter in the model summary, but how can we interpret the value of this ‘effect size’.
For instance, when is a value small, medium or large and can it be interpreted in the same way as in a regression analysis?
And finally, how much importance should we give to this parameter in the context of the whole (moderation) analysis.
Also, papers with examples on how to report on this are very much appreciated.
Warm regards from rainy Amsterdam
Question
I'm looking for an alternative for the parent-rated BRIEF (Behavior Rating Inventory of Executive Function) to use in a studie of children (aged 8 to 12) with ADHD. I'm specifically interested in an EF questionnaire that measures working memory. Preferably a questionnaire that has been translated into Dutch.
Thanks!
