WHAT'S KNOWN ON THIS SUBJECT: Children with attentiondeficit/hyperactivity disorder (ADHD) have poorer academic and social functioning and more language problems than typically developing peers. However, it is unknown how language problems impact the academic and social functioning of these children.WHAT THIS STUDY ADDS: Language problems are common in children with ADHD and are associated with markedly poorer academic functioning independent of ADHD symptom severity and comorbidities. There was little evidence that language problems were associated with poorer social functioning for children with ADHD.abstract OBJECTIVES: To examine the prevalence of language problems in children with attention-deficit/hyperactivity disorder (ADHD) versus non-ADHD controls, and the impact of language problems on the social and academic functioning of children with ADHD.METHODS: Children (6 to 8 years) with ADHD (n = 179) and controls (n = 212) were recruited through 43 Melbourne schools. ADHD was assessed by using the Conners 3 ADHD Index and the Diagnostic Interview Schedule for Children IV. Oral language was assessed by using the Clinical Evaluation of Language Fundamentals, fourth edition, screener. Academic functioning was measured via direct assessment (Wide Range Achievement Test 4) and teacher report (Social Skills Improvement System). Social functioning was measured via parent and teacher report (Strengths and Difficulties Questionnaire; Social Skills Improvement System). Logistic and linear regression models were adjusted for sociodemographic factors and child comorbidities. RESULTS:Children with ADHD had a higher prevalence of language problems than controls after adjustment for sociodemographic factors and comorbidities (odds ratio, 2.8; 95% confidence interval [CI], 1.5 to 5.1). Compared with children with ADHD alone, those with language problems had poorer word reading (mean difference [MD], 211.6; 95% CI, 216.4 to 26.9; effect size, 20.7), math computation (MD, 211.4; 95% CI, 215.0 to 27.7; effect size, 20.8), and academic competence (MD, 210.1; 95% CI, 214.0 to 26.1; effect size, 20.7). Language problems were not associated with poorer social functioning. CONCLUSIONS:Children with ADHD had a higher prevalence of language problems than controls, and language problems in children with ADHD contributed to markedly poorer academic functioning.

WHAT'S KNOWN ON THIS SUBJECT: Children who have attentiondeficit/hyperactivity disorder (ADHD) attending clinical services have poorer outcomes in adolescence on a range of measures. However, it is unknown how early in development these impairments appear, particularly for community-ascertained samples.WHAT THIS STUDY ADDS: At age 6 to 8 years, children in the community with ADHD have significantly poorer mental health, academic performance and social function compared with control children. Children who have impairing ADHD symptoms should be referred early for assessment and intervention. abstract OBJECTIVES: To examine the functional status (mental health, academic performance, peer problems) of a community-based sample of children who have attention-deficit/hyperactivity disorder (ADHD) and non-ADHD controls, and to investigate gender and subtype differences. METHODS:Children aged 6 to 8 years were recruited through 43 Melbourne schools, using a 2-stage screening (parent and teacher Conners 3 ADHD index) and case confirmation (Diagnostic Interview Schedule for Children, Version IV; [DISC-IV]) procedure. Outcome measures were mental health disorders (DISC-IV), academic performance (Wide Range Achievement Test 4), and peer problems (Strength and Difficulties Questionnaire). Unadjusted and adjusted linear and logistic regression were used to compare ADHD and non-ADHD controls.RESULTS: A total of 179 children who have ADHD and 212 non-ADHD controls were recruited. Compared with controls, children who had ADHD had higher odds of externalizing (odds ratio [OR], 11.0; 95% confidence interval [CI], 5.6-21.6; P , .001) and internalizing (OR, 2.9; 95% CI, 1.2-7.2; P = .02) disorders; poorer reading (effect size, 20.66) and mathematics (effect size, 20.69) performance; and more peer problems (P , .001). Boys and girls who had ADHD were equally impaired. Only 17% of children in our ADHD group had been previously diagnosed. Previous diagnosis was higher in the Combined group and for boys. CONCLUSIONS:In their second year of school, children who had ADHD performed worse than controls across all functional domains, yet only a minority had been formally diagnosed with ADHD. Findings highlight the need for earlier diagnosis and intervention.

Objective: The present study examined the impact of Attention Deficit Hyperactivity Disorder (ADHD) on core educational outcomes in two large community cohorts of Australian school children. Method: Academic (reading and numeracy) and non-academic (school engagement, attendance, peer victimization, and parental expectations) outcomes were compared between children with ADHD, subthreshold ADHD, and controls when children were in grade 5 (M age = 10.5). Data were drawn from the Longitudinal Study of Australian Children birth cohort (LSAC; N = 3,540) and the Children’s Attention Project (CAP; N = 356). Results: Both subthreshold ADHD and ADHD groups had poorer outcomes on all measures, with medium effects sizes. Differences were not evident between subthreshold ADHD and ADHD groups. Conclusions: Educational outcomes examined in this study highlight the educational risk for upperprimary school children with ADHD or subthreshold ADHD, in comparison to their peers. Monitoring these outcomes is necessary to inform policy, practice, and intervention.

Objective: This review aimed to understand the broader community’s attitudes toward ADHD, which could facilitate public health interventions to improve outcomes for individuals with ADHD. Methods: A standardized protocol identified peer-reviewed studies focusing on attitudes of broader community samples, published from January 2014 to February 2020 (inclusive). Results: A total of 1,318 articles were screened and 10 studies were included, examining attitudes of broader community samples from Australia, Sweden, Germany, Finland, Korea, Indonesia, and the United States. Findings revealed that broader community samples displayed varying degrees of ADHD-related knowledge, negative attitudes (that ADHD is over-diagnosed; that pharmacological treatment is not acceptable; that those with ADHD are more likely to exhibit poor behavior), and a desire for maintaining social distance from individuals with ADHD. Conclusion: Findings suggest that community attitudes are generally negative toward those with ADHD. Targeted mental health literacy could provide an important avenue for improving the broader community’s attitudes toward those with ADHD.
