ABSTRACT

Meta-analytic methods were used to examine global and domain-specific (i.e., academic, social, behavioral) self-esteem in children and adolescents with and without ADHD. Potential moderators of effect size heterogeneity were also examined via meta-regressions within a three-level approach. Findings from 49 aggregated global self-esteem effect sizes (ADHDN = 2500, TDN = 9448), 12 academic self-esteem effect sizes (ADHDN = 386, TDN = 315), 11 social self-esteem effect sizes (ADHDN = 258, TDN = 254), and 8 behavioral self-esteem effect sizes (ADHDN = 231, TDN = 211) suggest that children and adolescents with ADHD experience moderate global (ES = 0.46, p < .001), academic (ES = 0.60, p = .009), and social (ES = 0.67, p = .001) self-esteem impairments compared to children and adolescents without the disorder. The aggregated behavioral self-esteem effect size (ES = 0.20, p = .54), however, was not significant, and the global self-esteem effect size was markedly smaller compared to effect sizes for the academic and social domains. Further, examination of potential moderators of effect size heterogeneity indicated null effects for medication status, diagnostic complexity, informant, age, sex, comorbid psychopathology, and self-esteem dimension. Collectively, findings suggest that children and adolescents with ADHD do not hold a ubiquitous negative self-perception of difficulties across academic, social, and behavioral domains of functioning, and unexamined domains that are distal to ADHD may serve to bolster global self-esteem.

ABSTRACT

Previous examinations of working memory impairments in children with attention-deficit/hyperactivity disorder (ADHD) have predominantly focused on discreet visuospatial and phonological subsystem processes, as well as the domain-general central executive. The episodic buffer component of working memory, a neurocognitive process that allows for temporary storage and maintenance of bound episodes/features of information, is understudied in ADHD and initial findings have been equivocal. Heterogeneity in previous findings may reflect between-study methodological variability, floor effects unrelated to episodic buffer processes (i.e., excessive central executive demands), and limitations associated with previous investigations' use of novel paradigms. This study examined ADHD-related episodic buffer processing via an established paradigm (Allen et al., 2006) in well-defined groups of children with attention-deficit/hyperactivity disorder (ADHD) and typically developing peers (TD). Seventy-one children (ADHD n = 34, TD n = 37) aged 8-12 years (M = 9.81, SD = 1.50; 32% female) completed two conditions of a computerized working memory task that presented single feature stimuli (color and shape), and a third condition that presented dual-feature stimuli (color/shape binding). Overall, the ADHD group exhibited a large-magnitude deficit during the color/shape binding condition (d = .77), and both groups evinced worse performance accuracy in the color/shape binding condition compared to the single feature color and shape conditions. Collectively, these findings appear to provide evidence that children with ADHD exhibit large magnitude episodic buffer deficits that are not attributable to visuospatial subsystem or domain-general central executive processes.

ABSTRACT

Meta-analytic methods were used to examine ADHD-related risk-taking in children and adults, and to compare the magnitude of risk taking across behavioral, self-report, and virtual reality metrics. Potential moderators of effect size heterogeneity were also examined via a three-level multi-level approach and a hybrid meta-analytic/systematic review approach. Aggregated effect sizes obtained from 56 behavioral-task studies (82 effect sizes; ADHDN = 2577; TDN = 2606), 51 self-report studies (130 effect sizes; ADHDN = 18,641; TDN = 113,163), and 8 virtual reality studies (16 effect sizes; ADHDN = 382; TDN = 436) suggest that children and adults with ADHD exhibit moderately more risk-taking compared to children and adults without the disorder. Notably, the aggregated effect size obtained from virtual reality simulations (Hedges', g = 0.43) was 30-40% larger than effect sizes obtained from self-report and behavioral task metrics (Hedges' g = 0.31 and 0.27), respectively. Suboptimal Decision Making was the only significant moderator identified via multi-level modeling; however, comparison of subgroup effect sizes revealed potential moderating effects of ADHD presentation and trial-by-trial feedback on behavioral tasks. Collectively, findings suggest that ADHD is reliably associated with small to moderate magnitude greater risk-taking behavior and virtual reality simulations appear be the most sensitive currently available metric.
