The role of working memory and organizational skills in academic functioning for children with attention-deficit/hyperactivity disorder.

OBJECTIVE: Children with attention-deficit/hyperactivity disorder (ADHD) exhibit difficulties with organizational skills such as task planning, managing materials, and organizing activities that have downstream consequences on academic functioning. At the same time, deficits in working memory have been linked with both the organizational skills difficulties and academic underachievement and underperformance observed in children with ADHD and have been hypothesized to account for the link between organizational and academic functioning. However, the extent to which working memory and organizational skills independently versus jointly contribute to ADHD-related academic difficulties remains unclear. METHOD: The present study is the first to examine the unique and shared roles of working memory and organizational skills for explaining ADHD-related underachievement and underperformance in a clinically evaluated sample of 309 children with and without ADHD (Mage = 10.34, SD = 1.42; 123 girls; 69.6% White Not Hispanic or Latino). RESULTS: Bias-corrected, bootstrapped latent path analyses revealed that working memory and organizational skills together accounted for 100% of the academic achievement (d = -1.09) and 80.6% of the academic performance (d = -0.58) difficulties exhibited by children with ADHD. Working memory (d = -0.95 to -0.26), organizational skills (d = -0.30 to -0.11), and shared variance across working memory and organizational skills (d = -0.13 to -0.06) each independently predicted ADHD-related difficulties in both academic achievement and performance outcomes. CONCLUSIONS: These findings are consistent with models suggesting that working memory has downstream consequences for functional impairments in ADHD, as well as evidence that organizational skills and working memory are each important predictors of ADHD-related academic functioning.

Improving the efficacy and effectiveness of evidence-based psychosocial interventions for attention-deficit/hyperactivity disorder (ADHD) in children and adolescents.

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent, chronic, and impairing mental health disorder of childhood. Decades of empirical research has established a strong evidence-based intervention armamentarium for ADHD; however, limitations exist in regards to efficacy and effectiveness of these interventions. We provide an overview of select evidence-based interventions for children and adolescents, highlighting potential approaches to further improving the efficacy and effectiveness of these interventions. We conclude with broader recommendations for interventions, including considerations to moderators and under-explored intervention target areas as well as avenues to improve access and availability of evidence-based interventions through leveraging underutilized workforces and leveraging technology.

Working memory and inhibitory control deficits in children with ADHD: an experimental evaluation of competing model predictions.

Introduction: Children with ADHD demonstrate difficulties on many different neuropsychological tests. However, it remains unclear whether this pattern reflects a large number of distinct deficits or a small number of deficit(s) that broadly impact test performance. The current study is among the first experiments to systematically manipulate demands on both working memory and inhibition, with implications for competing conceptual models of ADHD pathogenesis. Method: A clinically evaluated, carefully phenotyped sample of 110 children with ADHD, anxiety disorders, or co-occurring ADHD+anxiety (Mage=10.35, 44 girls; 69% White Not Hispanic/Latino) completed a counterbalanced, double dissociation experiment, with two tasks each per inhibition (low vs. high) x working memory (low vs. high) condition. Results: Bayesian and frequentist models converged in indicating that both manipulations successfully increased demands on their target executive function (BF10>5.33x108, p<.001). Importantly, occupying children's limited capacity working memory system produced slower response times and reduced accuracy on inhibition tasks (BF10>317.42, p<.001, d=0.67-1.53). It also appeared to differentially reduce inhibition (and non-inhibition) accuracy for children with ADHD relative to children with anxiety (BF10=2.03, p=.02, d=0.50). In contrast, there was strong evidence against models that view working memory deficits as secondary outcomes of underlying inhibition deficits in ADHD (BF01=18.52, p=.85). Discussion: This pattern indicates that working memory broadly affects children's ability to inhibit prepotent tendencies and maintain fast/accurate performance, and may explain the errors that children with ADHD make on inhibition tests. These findings are broadly consistent with models describing working memory as a causal mechanism that gives rise to secondary impairments. In contrast, these findings provide evidence against models that view disinhibition as a cause of working memory difficulties or view working memory as a non-causal correlate or epiphenomenon in ADHD.

Social functioning in children with ADHD: an examination of inhibition, self-control, and working memory as potential mediators.

Children with attention-deficit/hyperactivity disorder (ADHD) experience a host of social problems, in addition to significant impairments in behavioral inhibition, working memory, and self-control. Behavioral inhibition and working memory difficulties have been linked with social functioning deficits, but to date, most studies have examined these neurocognitive problems either in isolation or as an aggregate measure in relation to social problems, and none has considered the role of self-control. Thus, it remains unclear whether all of these executive functions are linked with social problems or if the link can be more parsimoniously explained by construct overlap. Fifty-eight children with ADHD and 63 typically developing (TD) children completed tests assessing self-control, behavioral inhibition, and working memory; parents and teachers rated children's social functioning. Examination of potential indirect effects with the bootstrapping procedure indicated that working memory mediated the relation between group membership (ADHD, TD) and child social functioning based on teacher but not parent ratings. Behavioral inhibition and self-control did not have direct relations with either parent- or teacher-rated social functioning. These findings point to important differences regarding how executive functioning difficulties manifest at school compared to home, as well as the specific executive function components that predict ADHD-related social difficulties.

[Formula: see text] Neurocognition in children with cognitive disengagement syndrome: accurate but slow.

Cognitive disengagement syndrome (CDS), previously termed sluggish cognitive tempo (SCT), is characterized by excessive daydreaming, mental confusion, and slowed behavior or thinking. Prior research has found inconsistent relations between CDS and neurocognition, though most studies have used small or ADHD-defined samples, non-optimal measures of CDS, and/or examined limited neurocognitive domains. Accordingly, this study examined the association of parent- and teacher-reported CDS symptoms using a comprehensive neurocognitive battery in a sample of 263 children (aged 8-12) selected with a range of CDS symptomatology. Parents and teachers provided ratings of CDS and ADHD inattentive (ADHD-IN) symptoms. Path analyses were conducted to examine CDS and ADHD-IN as unique predictors of neurocognitive functioning after covarying for age, sex, and family income. CDS symptoms were uniquely associated with slower performance across a range of cognitive domains, including verbal inhibition, rapid naming/reading, planning, divided attention, and set shifting. In contrast, ADHD-IN symptoms were uniquely associated with poorer performance on a Go/NoGo task (inhibition/distractibility), visual scanning and discrimination, and interference control. Findings from the current study, amongst the first to recruit children based on levels of CDS symptomatology, provide the strongest evidence to date that the neurocognitive phenotype of CDS is characterized by slowed cognitive processing, and add to its validity as a separate syndrome from ADHD. If replicated, these findings have implications for assessment, treatment, and school accommodations for CDS. Neuroimaging studies exploring the neurobiological basis of CDS are also needed.

ADHD, chronotype, and circadian preference in a multi-site sample of college students.

Attention-deficit/hyperactivity disorder and an evening chronotype are both common among college students, and there is growing interest in understanding the possible link between attention-deficit/hyperactivity disorder and circadian function. However, mixed findings have been reported, and many of the existing studies have used small samples that were unable to examine chronotype across attention-deficit/hyperactivity disorder presentations. Participants were 4751 students (73% female; 80% White), aged 18-29 years (M = 19.28, SD = 1.50), from five universities who completed measures assessing attention-deficit/hyperactivity disorder, depressive and anxiety symptoms, as well as the Morningness-Eveningness Questionnaire to assess chronotype (categorical) and circadian preference (dimensional). Participants with either attention-deficit/hyperactivity disorder predominantly inattentive presentation or attention-deficit/hyperactivity disorder combined presentation had higher rates of being an evening type (47.2% and 41.5%, respectively) than participants without elevated attention-deficit/hyperactivity disorder (28.5%), and participants with attention-deficit/hyperactivity disorder predominantly inattentive presentation also had higher rates of being an evening type than participants with attention-deficit/hyperactivity disorder predominantly hyperactive-impulsive presentation (30.7%). Dimensional analyses indicated that attention-deficit/hyperactivity disorder inattentive symptoms were more strongly associated than hyperactive-impulsive symptoms with eveningness preference. Finally, greater eveningness preference strengthened the association between attention-deficit/hyperactivity disorder inattention and depressive symptoms but not anxiety symptoms. This is the largest study to document that college students with elevated attention-deficit/hyperactivity disorder symptoms are more likely to be evening types than other college students, and inattentive symptoms in particular are associated with later circadian preference.

Working memory and math skills in children with and without ADHD.

OBJECTIVE: Children with attention-deficit/hyperactivity disorder (ADHD) frequently demonstrate deficits in working memory and in multiple domains of math skills, including underdeveloped problem-solving and computation skills. The Baddeley model of working memory posits a multicomponent system, including a domain-general central executive and two domain-specific subsystems-phonological short-term memory and visuospatial short-term memory. Extant literature indicates a strong link between neurocognitive deficits in working/short-term memory and math skills; however, the extent to which each component of working/short-term memory may account for this relation is unclear. METHOD: The present study was the first to use bifactor (S·I-1) modeling to examine relations between each working/short-term memory subcomponent (i.e., central executive, phonological short-term memory, and visuospatial short-term memory), ADHD symptoms, and math skills in a clinically evaluated sample of 186 children ages 8-13 (Myears = 10.40, SD = 1.49; 62 girls; 69% White/non-Hispanic). RESULTS: Structural equation modeling indicated that all three working/short-term memory components exert a significant and approximately equal effect on latent math skills (ß = .29-.50, all p < .05) and together explain 56% of the variance in children's math achievement (R² = .56). Exploratory analyses indicated that teacher-reported ADHD inattentive symptoms provided a small but significant contribution to predicting latent math skills (ΔR² = .07) and accounted for 24% of the central executive/math association. CONCLUSIONS: These findings suggest that math difficulties in children with ADHD and clinically evaluated children without ADHD are associated, in large part, with their neurocognitive vulnerabilities in working/short-term memory and, to a lesser extent, overt ADHD symptoms.

Does Anxiety Systematically Bias Estimates of Executive Functioning Deficits in Pediatric Attention-Deficit/Hyperactivity Disorder?

Growing evidence suggests that childhood ADHD is associated with larger impairments in working memory relative to inhibition. However, most studies have not considered the role of co-occurring anxiety on these estimates - a potentially significant confound given prior evidence that anxiety may increase working memory difficulties but decrease inhibition difficulties for these children. The current study extends prior work to examine the extent to which co-occurring anxiety may be systematically affecting recent estimates of the magnitude of working memory/inhibitory control deficits in ADHD. The carefully-phenotyped sample included 197 children with ADHD and 142 children without ADHD between the ages of 8 and 13 years (N = 339; Mage = 10.31, SD = 1.39; 144 female participants). Results demonstrated that ADHD diagnosis predicted small impairments in inhibitory control (d = 0.31) and large impairments in working memory (d = 0.99). However, child trait anxiety assessed dimensionally across multiple informants (child, parent, teacher) did not uniquely predict either executive function, nor did it moderate estimates of ADHD-related working memory/inhibition deficits. When evaluating anxiety categorically and controlling for ADHD, anxiety diagnosis predicted slightly better working memory (d = 0.19) but not inhibitory control for clinically evaluated children generally. Findings from the current study indicate that trait anxiety, measured dimensionally or categorically, does not differentially affect estimates of executive dysfunction in pediatric ADHD. Further, results suggest that trait anxiety is generally not associated with executive dysfunction above and beyond the impact of co-occurring ADHD. Future research is needed to further assess the role of anxiety in ADHD behavioral symptomatology, neurocognitive functioning, and mechanisms underlying these relations.

Evaluating the Simple View of Reading for Children With Attention-Deficit/Hyperactivity Disorder.

The 'simple view of reading' is an influential model of reading comprehension which asserts that children's reading comprehension performance can be explained entirely by their decoding and language comprehension skills. Children with ADHD often exhibit difficulty across all three of these reading domains on standardized achievement tests, yet it is unclear whether the simple view of reading is sufficient to explain reading comprehension performance for these children. The current study was the first to use multiple indicators and latent estimates to examine the veracity of key predictions from the simple view of reading in a clinically-evaluated sample of 250 children with and without ADHD (ages 8-13, Mage=10.29, SD=1.47; 93 girls; 70% White/Non-Hispanic). Results of the full-sample structural equation model revealed that decoding and language comprehension explained all (R2=.99) of the variance in reading comprehension for children with and without ADHD. Further, multigroup modeling (ADHD, Non-ADHD) indicated that there was no difference in the quantity of variance explained for children with ADHD versus clinically-evaluated children without ADHD, and that the quantity of explained variance did not differ from 100% for either group. Sensitivity analyses indicated that these effects were generally robust to control for monomethod bias, time sampling error, and IQ. These findings are consistent with 'simple view' predictions that decoding and language comprehension are both necessary and together sufficient for explaining children's reading comprehension skills. The findings extend prior work by indicating that the 'simple view' holds for both children with ADHD and clinically-evaluated children without ADHD.

A preliminary 'shortlist' of individual, family, and social-community assets to promote resilience in pediatric ADHD.

BACKGROUND: Understanding factors that promote resilience in pediatric ADHD is important though highly understudied. AIMS: The current study sought to provide a preliminary 'shortlist' of key individual, family, and social-community assets among children with ADHD. METHODS AND PROCEDURES: The study included well-characterized, clinically-evaluated samples of children with (n=108) and without ADHD (n=98) ages 8-13 years (M=10.31; 41.3% girls; 66.5% White/Non-Hispanic). All subsets regression and dominance analysis identified the subset of predictors that accounted for the most variance in broad-based resilience for children with ADHD and their relative importance. Findings were compared for children with versus without ADHD as preliminary evidence regarding the extent to which identified assets are promotive, protective, or conditionally helpful. OUTCOMES AND RESULTS: Higher levels of peer acceptance, social skills, and academic performance were top predictors of resilience among children with ADHD. Better child working memory, attention, higher levels of hyperactivity, older age, and fewer parent self-reported mental health concerns were also identified as predictors of resilience in ADHD. Both overlapping and unique factors were associated with resilience for children with versus without ADHD. Conclusions and Results: These results, if replicated, provide a strong preliminary basis for strength-based basic/applied research on key assets that promote resilience in ADHD.

Central executive training for ADHD: Impact on organizational skills at home and school. A randomized controlled trial.

OBJECTIVE: The current randomized controlled trial (RCT) was the first to examine the benefits of central executive training (CET, which trains the working components of working memory [WM]) for reducing organizational skills difficulties relative to a carefully matched neurocognitive training intervention (inhibitory control training [ICT]). METHOD: A carefully phenotyped sample of 73 children with attention-deficit/hyperactivity-impulsivity disorder (ADHD; ages 8-13, M = 10.15, SD = 1.43; 20 girls; 73% White/Non-Hispanic) participated in a preregistered RCT of CET versus ICT (both 10-week treatments). Parent-rated task planning, organized actions, and memory/materials management data were collected at pretreatment, posttreatment, and 2-4 month follow-up; teacher ratings were obtained at pretreatment and 1-2 month follow-up. RESULTS: CET was superior to ICT for improving organizational skills based on teacher report (Treatment × Time interaction: d = 0.61, p = .01, BF10 = 31.61). The CET group also improved significantly based on parent report, but this improvement was equivalent in both groups (main effect of time: d = 0.48, p < .001, BF10 = 3.13 × 107; Treatment × Time interaction: d = 0.29, p = .25, BF01 = 3.73). Post hocs/preregistered planned contrasts indicated that CET produced significant and clinically meaningful (number needed to treat = 3-8) pre/post gains on all three parent (d = 0.50 -0.62) and all three teacher (d = 0.46 -0.95) subscales, with gains that were maintained at 1-2 month (teacher report) and 2-4 month follow-up (parent report) for five of six outcomes. CONCLUSIONS: Results provide strong initial evidence that CET produces robust and lasting downstream improvements in school-based organizational skills for children with ADHD based on teacher report. These findings are generally consistent with model-driven predictions that ADHD-related organizational problems are secondary outcomes caused, at least in part, by underdeveloped working memory abilities.

The relation between executive functions, error-related brain activity, and ADHD symptoms in clinically evaluated school-aged children.

Two event-related potentials (ERPs) elicited following errors, the error-related negativity (ERN) and error positivity (Pe), have been proposed to reflect cognitive control, though the specific processes remain debated. Few studies have examined the ERN and Pe's relations with individual differences in cognitive control/executive functioning using well-validated tests administered separately from the inhibition tasks used to elicit the ERN/Pe. Additionally, neurocognitive tests of executive functions tend to strongly predict ADHD symptoms, but the extent to which task-based and EEG-based estimates of executive functioning/cognitive control account for the same variance in ADHD symptoms remains unclear. The current study addressed these limitations by examining relations between the ERN/Pe and three core executive functions (working memory, inhibitory control, set shifting) in a clinically-evaluated sample of 53 children ages 8-12 (Mage = 10.36, SD = 1.42; 77.4% White/Non-Hispanic; 16 girls) with and without ADHD. Results demonstrated that neither the ERN nor Pe were related to overall cognitive control/executive functioning, or to working memory or set shifting specifically (all 95%CIs include 0.0). In contrast, a larger Pe was associated with better-developed inhibitory control (ß=-.35, 95%CI excludes 0.0), but did not capture aspects of inhibitory control that are important for predicting ADHD symptoms. Neither the ERN nor Pe predicted ADHD symptoms (95%CIs include 0.0). Results were generally robust to control for age, sex, SES, ADHD symptom cluster, and anxiety, and emphasize the need for caution when interpreting the ERN/Pe as indices of broad-based cognitive control/executive functioning, as well as using the ERN/Pe to examine cognitive processes contributing to ADHD symptomatology.

[Formula: see text] Does training working memory or inhibitory control produce far-transfer improvements in set shifting for children with ADHD? A randomized controlled trial.

Children with ADHD show impairments in set shifting task performance. However, the limited available evidence suggests that directly training shifting may not improve shifting performance in this population. We hypothesized that this incongruence may be because impairments exhibited by children with ADHD during shifting tasks are due to deficits in other executive functions, as shifting tasks also engage children's working memory and/or inhibitory control abilities. This randomized controlled trial examined the extent to which neurocognitive training of working memory vs. inhibitory control can produce downstream (far-transfer) improvements in set shifting task performance. Children with ADHD ages 8-12 (M = 10.41, SD = 1.46; 12 girls; 74% White/Non-Hispanic) were randomized to either central executive training (CET; n = 25) or inhibitory control training (ICT; n = 29), two next-generation digital therapeutics previously shown to improve their intended neurocognitive targets. Two criterion set shifting tests were administered at pre- and post-treatment. Results indicated that ICT was superior to CET for improving shifting accuracy (treatmentxtime: p = .03, BF10 = 3.01, η2 = .09, d = 0.63). ICT was also superior to CET for improving shifting speed, albeit on only one of the two outcome tasks (p = .02, BF10 = 4.53, η2 = .08, d = 0.59). CET did not produce improvements in shifting speed or accuracy on either task (p > .52, BF01 > 2.62), but showed evidence for more general (non-shifting-specific) improvement in response times on one of the outcome tasks (shift trials, d = 0.70; non-shift trials, d = 0.68). Taken together, these findings confirm that inhibitory control is important for successful performance on shifting tests, and suggest that training inhibitory control may reflect a method for improving set shifting difficulties in children with ADHD.

Is reduced social competence a mechanism linking elevated autism spectrum symptoms with increased risk for social anxiety?

OBJECTIVES: Approximately 50% of children with autism spectrum disorder (ASD) develop comorbid social anxiety disorder, and this comorbidity predicts poorer treatment outcomes than either syndrome alone. ASD and social anxiety are both associated with reduced social competence as evidenced by difficulties implementing fundamental social skills for successful social interactions, but it remains unclear whether reduced social competence reflects a mechanism that explains the increased risk for social anxiety associated with elevated autism spectrum symptoms. DESIGN/METHODS: To address this gap in the literature, the current study combined multi-informant measures (child, parent and teacher report) with a sample of 194 children with and without psychiatric disorders (ages 8-13; 68 girls; 69% White/Non-Hispanic). Autism spectrum traits, social competence and social anxiety symptoms were measured continuously. RESULTS: Bias-corrected, bootstrapped conditional effects modelling indicated that elevated parent-reported autism spectrum symptoms predicted reduced teacher-perceived social competence (ß = -.21) and elevated child self-reported social anxiety (ß = .17); reduced social competence accounted for 20% of the autism/social anxiety link (indirect pathway ß = .04, ER = .20), and reduced social competence also predicted higher social anxiety independent of autism symptoms (ß = -.16; all 95% CIs exclude 0.0, indicating significant effects). Exploratory analyses suggested that these findings were driven primarily by autism spectrum social communication difficulties rather than restricted/repetitive behaviours/interests. CONCLUSIONS: The current findings are consistent with prior work implicating reduced social competence as a risk factor for the development of social anxiety among children with ASD, and extend prior work by demonstrating that this link is robust to control for mono-informant/mono-measure bias, age, sex, SES, majority/minoritized race/ethnicity status, clinical comorbidities, and item overlap across measures.

Are Reading Interventions Effective for At-Risk Readers with ADHD? A Meta-Analysis.

OBJECTIVE: Utilizing a multi-level meta-analytic approach, this review is the first to systematically quantify the efficacy of reading interventions for school-aged children with ADHD and identify potential factors that may increase the success of reading-related interventions for these children. METHOD: 18 studies (15 peer-reviewed articles, 3 dissertations) published from 1986 to 2020 (N = 564) were meta-analyzed. RESULTS: Findings revealed reading interventions are highly effective for improving reading skills based on both study-developed/curriculum-based measures (g = 1.91) and standardized/norm-referenced achievement tests (g = 1.11) in high-quality studies of children with rigorously-diagnosed ADHD. Reading interventions that include at least 30 hours of intervention targeting decoding/phonemic awareness meet all benchmarks to be considered a Level 1 (Well-Established) Evidence-Based Practice with Strong Research Support for children with ADHD based on clinical and special education criteria. CONCLUSIONS: Our findings collectively indicate that reading interventions should be the first-line treatment for reading difficulties among at-risk readers with ADHD.

Linking ADHD and ASD Symptomatology with Social Impairment: The Role of Emotion Dysregulation.

Children with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) often experience social impairments. These children also frequently struggle with emotion regulation, and extant literature suggests that emotion dysregulation predicts social impairment in both clinical and neurotypical populations. However, the evidence base linking ADHD/ASD with social impairment comes primarily from samples meeting full diagnostic criteria for ADHD and/or ASD despite evidence that both syndromes reflect extreme ends of natural continuums that are normally distributed across the general population. To our knowledge, the present study is the first to concurrently examine unique and overlapping relations among ADHD/ASD symptoms, emotion regulation, and social difficulties using multi-informant measures (parent, teacher) with a clinically-evaluated sample of 108 children ages 8-13 (40 girls; 66% White/Non-Hispanic) with and without clinically-elevated ASD and ADHD symptoms and other common clinical disorders. Bias-corrected, bootstrapped conditional effects modeling revealed that ADHD-inattentive (ß=-0.23) and ASD-social communication (ß=-0.20) symptoms predicted social impairment directly, whereas ADHD-hyperactive/impulsive (ß=-0.06) and ASD-restricted/repetitive behavior/interests (ß=-0.06) symptoms predicted social impairment only via their shared associations with emotion dysregulation. Sensitivity analyses revealed that most relations were robust to control for item overlap across measures. In contrast, only the ADHD-inattention/social impairment link was robust to control for mono-informant bias, highlighting the importance of multi-informant methods and the potential for different determinants of social functioning across settings. Overall, this study implicates emotion regulation skills and all four ADHD/ASD symptom clusters as potential influences on children's social functioning, albeit with a more nuanced and potentially setting-specific pattern than suggested by prior work.

Does central executive training and/or inhibitory control training improve emotion regulation for children with attention-deficit/hyperactivity disorder? A randomized controlled trial.

Introduction: Approximately 48-54% of children with attention-deficit/hyperactivity disorder (ADHD) have impairing difficulties with emotion regulation, and these difficulties are not ameliorated by first-line ADHD treatments. Working memory and inhibitory control represent promising intervention targets given their functional, if not causal, links with ADHD-related emotion dysregulation. Methods: This preregistered randomized controlled trial tested whether two digital therapeutic training protocols that have been previously shown to improve working memory (Central Executive Training [CET]) and inhibitory control (Inhibitory Control Training [ICT]) can improve emotion regulation in a sample of 94 children with ADHD aged 8-13 years (M = 10.22, SD = 1.43; 76% White/non-Hispanic; 29 girls). Results: Results of Bayesian mixed model ANOVAs indicated both treatment groups demonstrated significant decreases in emotion dysregulation relative to pre-treatment at immediate post-treatment (parent report; d = 1.25, BF10 = 8.04 × 1013, p < 0.001), at 1-2 months after completing treatment (teacher report; d = 0.99, BF10 = 1.22 × 106, p < 0.001), and at 2-4-months follow-up (parent report; d = 1.22, BF10 = 1.15 × 1014, p < 0.001). Contrary to our hypotheses, the CET and ICT groups demonstrated equivalent reductions in emotion dysregulation and maintenance of effects. Exploratory analyses revealed that results were robust to control for informant expectancies, ADHD medication status/changes, in-person vs. at-home treatment, child age, and time from treatment completion to post-treatment ratings. Discussion: To determine whether working memory and inhibitory control are causally linked with ADHD-related emotion dysregulation, future studies should include active control conditions that do not train executive functions prior to making decisions about the clinical utility of CET/ICT for the treatment of emotion dysregulation in ADHD. Clinical trial registration: [https://clinicaltrials.gov/], identifier [NCT03324464].

ADHD and dangerous driving in emerging adults: The moderating role of family climate for road safety.

Dangerous driving accounts for 95% of driving fatalities among emerging adults. Emerging adult drivers exhibiting symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) are at greater risk for motor vehicle crashes and engaging in unsafe driving practices; however, not all individuals with ADHD symptoms exhibit such risk. Several studies have found that drivers' perceptions of their family's values and priorities related to driving practices predict driving outcomes among emerging adults; these factors have not been examined in the context of ADHD symptomology. We examined family climate for road safety as a moderator of ADHD symptoms and dangerous driving behaviors in a sample of college students. A total of 4,392 participants completed surveys measuring self-reported ADHD symptoms, dangerous driving behavior, and family climate for road safety. Results indicated that higher levels of parental feedback weakened the relation between ADHD symptoms and aggressive driving; higher levels of parental monitoring strengthened this relationship. Higher levels of parental monitoring strengthened the association between ADHD symptoms and negative emotion while driving. When participants perceived their parents as having high levels of noncommitment to road safety, the association between ADHD symptoms and self-reported risky driving increased. Higher levels of open communication about unsafe driving attenuated the relation between ADHD and risky driving. Overall, some but not all components of family climate for road safety appear to affect the relation between ADHD symptoms and dangerous driving in the expected direction.

Does Child Anxiety Exacerbate or Protect Against Parent-Child Relationship Difficulties in Children with Elevated ADHD Symptoms?

Pediatric ADHD is associated with parent-child relationship difficulties. However, the extent to which these relations are attributable to specific ADHD symptom clusters (i.e., inattentive vs. hyperactive/impulsive), and the extent to which child anxiety symptoms may exacerbate or protect against these difficulties, remains unclear. To address these gaps in the literature, the current study combined multi-informant measures (parent, teacher, child) with a clinically-evaluated and carefully-phenotyped sample of 188 children with and without ADHD and anxiety (ages 8-13; 63 girls). Results indicated that child-reported anxiety (ß = .46) and teacher-reported inattentive (ß = .71) symptoms, and their interaction (ß = -1.06), along with child age and IQ (ß = -.14 to -.15), predict the extent to which parents perceive themselves as confident and competent parents (all p < .05). In contrast, only comorbid oppositional-defiant disorder conferred risk for increased parent-reported relational frustration, and we were unable to detect any reliable child-level demographic, diagnostic, or behavioral predictors of parent-reported discipline practices. These findings were robust to control for child demographic characteristics, clinical diagnoses, and intellectual functioning, with sensitivity analyses highlighting the importance of assessing ADHD inattentive vs. hyperactive/impulsive symptoms separately for understanding parenting outcomes. Taken together, the current findings suggest that child ADHD and anxiety symptoms may influence specific rather than broad-based aspects of the parent-child relationship, and produce differently valenced outcomes in the presence vs. absence of the other condition. Interestingly, it appears that the combination of greater child inattention and anxiety, rather than elevations in either symptom domain independently, predict adverse parenting outcomes in terms of reduced parental confidence.

Central executive training for ADHD: Effects on academic achievement, productivity, and success in the classroom.

OBJECTIVE: Central executive training (CET) is a "Level 2" evidence-based treatment for improving ADHD-related executive dysfunction and behavioral symptoms, but the extent to which these gains extend to the disorder's well-documented academic difficulties is unknown. METHOD: Across two clinical trials, 108 children with attention-deficit/hyperactivity disorder (ADHD) 8-13 years old (M = 10.29, SD = 1.50; 32 girls; 75% White/Non-Hispanic) were treated with CET (n = 52), inhibitory control training (ICT; n = 29), or gold-standard behavioral parent training (BPT; n = 27). RESULTS: CET was superior to BPT and ICT (d = 0.62-0.88) for improving masked teacher perceptions of academic success, impulse control, and academic productivity at 1-2 months posttreatment. At 2-4-month follow-up, CET (d = 0.76) and ICT (d = 0.54) were superior to BPT for improving objectively-tested academic achievement overall (reading comprehension, math problem-solving, language comprehension), and CET was superior to ICT (d = 0.56) for improving math problem-solving. The significant benefits of CET on academic success, academic productivity, reading comprehension, and math problem-solving replicated across both trials and were clinically significant as evidenced by low number needed to treat estimates (Needed to Treat; NNT = 3-7) and significantly higher proportions of individual cases demonstrating reliable improvements in academic success/productivity (33%-36% vs. 0%-18%) and achievement (38%-72% vs. 18%-54%) across outcomes (all p ≤ .01). CONCLUSIONS: Results across the two trials provide strong support for the efficacy of CET for ADHD, and are consistent with model-driven hypotheses that academic difficulties in ADHD are due, in part, to these children's underdeveloped executive functioning abilities.
