Identifying, evaluating, diagnosing, and treating ADHD in minority youth

The Role of Reactive Aggression in the Link Between Hyperactive-Impulsive Behaviors and Peer Rejection in Adolescents

Attention-deficit/hyperactivity disorder (ADHD) symptoms and aggressive behaviors are both associated with peer rejection, but little is known the nature of this association with respect to the two symptom dimensions of hyperactivity-impulsivity and inattention and different types of aggression. The present study examines the relations between dimensions of ADHD symptomatology, proactive and reactive aggression, and peer rejection in adolescence. Teacher-reported data were obtained for 200 high school students (grades 9-12; 48% female; predominately Latino). In structural equation modeling path analyses, the indirect effects of reactive aggression accounted for the link between hyperactivity-impulsivity and peer rejection. Within the same model, neither inattention nor proactive aggression were associated with peer rejection. These findings suggest that reactive aggression may be a key mechanism through which hyperactive-impulsive behavior is associated with peer rejection. Future research and intervention efforts should address the role of reactive aggression among youth with ADHD symptomatology.

Minorities are Disproportionately Underrepresented in Special Education: Longitudinal Evidence Across Five Disability Conditions

We investigated whether and to what extent minority children attending elementary and middle schools in the U.S. are over- or under-identified as disabled and so disproportionately represented in special education. To address existing limitations in the field's knowledge base, we (a) analyzed multi-year longitudinal data, (b) used hazard modeling to estimate over-time dynamics of disability identification across five specific conditions, and (c) extensively corrected for child-, family-, and school-level potential confounding variables (e.g., child-level academic achievement and behavior, family-level socioeconomic status, school-level state location). Despite long-standing and on-going federal legislative and policy efforts to reduce minority over-representation in special education, our analyses indicated that this has not been occurring in the U.S. Instead, minority children are less likely than otherwise similar White, English-speaking children to be identified as disabled and so receive special education services. From kindergarten entry to at least the end of middle school, racial and ethnic minority children are less likely than otherwise similar White children to be identified as having (a) learning disabilities, (b) speech or language impairments, (c) intellectual disabilities, (d) health impairments, or (d) emotional disturbances. Language minority children are less likely to be identified as having (a) specific learning disabilities or (b) speech or language impairments.

Racial/ethnic disparities in ADHD diagnosis by kindergarten entry

BACKGROUND

Whether and to what extent racial/ethnic disparities in attention-deficit/hyperactivity disorder (ADHD) diagnosis occur by kindergarten entry is currently unknown. We investigated risk factors associated with an ADHD diagnosis by kindergarten entry generally, and specifically whether racial/ethnic disparities in ADHD diagnosis occur by this very early time period.

METHODS

Secondary analysis of data from children enrolled in the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), a large, nationally representative cohort of U.S. children born in 2001. Data include information from birth certificates, parent and teacher questionnaires, and in-person developmental assessments conducted with children at intervals from 9 months through kindergarten entry. The analytic sample included children enrolled in the ECLS-B at the 60-month assessment (N = 6,550).

RESULTS

Black children in the United States were 70% (1 - OR of .30) less likely to receive an ADHD diagnosis than otherwise similar White children. Hispanic children initially appeared to be underdiagnosed for ADHD. However, their disparity with Whites became statistically nonsignificant after controlling for whether a language other than English was primarily spoken in the home. Analyses of kindergarten teacher-reported classroom behavior indicated that neither Black nor Hispanic children displayed less frequent ADHD-related behaviors than Whites.

CONCLUSIONS

Although they are not less likely to display ADHD-related behaviors, children who are Black or being raised in households where non-English is primarily spoken are less likely than otherwise similar White children to be diagnosed with ADHD in the US.

Adolescent and caregiver reports of ADHD symptoms among inner-city youth: agreement, perceived need for treatment, and behavioral correlates

OBJECTIVE

This study investigated adolescent and caregiver reports of ADHD symptoms in a sample of clinically referred inner-city adolescents.

METHOD

Participants (N = 168) included youth ages 12-18 (54% male, 98% ethnic minority) and their caregivers who each completed diagnostic interviews of ADHD symptoms and assessments of perceived need for ADHD treatment and correlated behavior problems.

RESULTS

Informants showed poor agreement on DSM-IV diagnostic categories and also dimensional scales, Inattention/Disorganization (I/D) and Hyperactivity/Impulsivity (H/I). Both caregiver and adolescent reports of I/D symptoms, but not H/I symptoms, were related to perceived need for ADHD treatment. Caregiver reports were linked to behavioral correlates typically associated with ADHD: I/D symptoms correlated with planning/organization and socioemotional deficits, and H/I symptoms correlated with externalizing and behavior regulation deficits. In contrast, adolescent reports of I/D were related to internalizing and externalizing problems, and their reports of H/I correlated with externalizing only. Few gender effects were found.

CONCLUSION

Study results underscore the developmental salience of I/D symptoms and have implications for ADHD diagnosis and treatment planning for adolescents.

Racial and ethnic disparities in ADHD diagnosis from kindergarten to eighth grade

OBJECTIVE

Whether and to what extent racial/ethnic disparities inattention-deficit/hyperactivity disorder (ADHD) diagnosis occur across early and middle childhood is currently unknown. We examined the over-time dynamics of race/ethnic disparities in diagnosis from kindergarten to eighth grade and disparities in treatment in fifth and eighth grade.

METHODS

Analyses of the nationally representative Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 (N = 17 100)using discrete-time hazard modeling.

RESULTS

Minority children were less likely than white children to receive an ADHD diagnosis. With time-invariant and -varying confounding factors statistically controlled the odds of ADHD diagnosis for African Americans, Hispanics, and children of other races/ethnicities were 69% (95% confidence interval [CI]: 60%–76%), 50% (95% CI: 34%–62%), and 46% (95% CI: 26%–61%) lower, respectively, than for whites. Factors increasing children’s risk of an ADHD diagnosis included being a boy,being raised by an older mother, being raised in an English-speaking household, and engaging in externalizing problem behaviors. Factors decreasing children’s risk of an ADHD diagnosis included engaging in learning-related behaviors (eg, being attentive), displaying greater academic achievement, and not having health insurance. Among children diagnosed with ADHD, racial/ethnic minorities were less likely than whites to be taking prescription medication for the disorder.

CONCLUSIONS

Racial/ethnic disparities in ADHD diagnosis occur by kindergarten and continue until at least the end of eighth grade. Measured confounding factors do not explain racial/ethnic disparities in ADHD diagnosis and treatment. Culturally sensitive monitoring should be intensified to ensure that all children are appropriately screened, diagnosed,and treated for ADHD.

The patient-centered medical home, practice patterns, and functional outcomes for children with attention deficit/hyperactivity disorder

OBJECTIVE

To determine whether children with attention deficit/hyperactivity disorder (ADHD) receive care in a patient-centered medical home (PCMH) and how that relates to their ADHD treatment and functional outcomes.

METHODS

Cross-sectional analysis of the 2007 National Survey for Children's Health, a nationally representative survey of 91,642 parents. This analysis covers 5169 children with parent-reported ADHD ages 6-17. The independent variable is receiving care in a PCMH. Main outcome measures are receiving ADHD medication, mental health specialist involvement, and functional outcomes (difficulties with participation in activities, attending school, making friends; having problem behaviors; missed school days; and number of times parents contacted by school).

RESULTS

Only 44% of children with ADHD received care in a PCMH. Children with ADHD receiving care in a PCMH compared with those who did not were more likely to receive medication for ADHD (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.1-1.9); less likely to have mental health specialist involvement (OR, 0.6; 95% CI, 0.4-0.7); less likely to have difficulties participating in activities (OR, 0.6; 95% CI 0.4-0.8), making friends (OR, 0.6; 95% CI, 0.5-0.9), and attending school (OR, 0.4; 95% CI, 0.3-06); less likely to have problem behaviors (OR 0.6; 95% CI 0.5-0.9); had fewer missed school days (β = -1.5, 95% CI -2.4 to -0.5); and parents were contacted by school less frequently (β = -0.2, 95% CI -0.3 to -0.1).

CONCLUSIONS

For children with ADHD, receiving care in a PCMH is associated with practice pattern change and better outcomes. The PCMH may represent a promising opportunity to improve quality of care and outcomes for children with ADHD.

Parents' conceptualization of adolescents' mental health problems: who adopts a psychiatric perspective and does it make a difference?

How parents give meaning to the problems of adolescents diagnosed with mental disorders and receiving treatment is likely related to important outcomes including parental well-being and commitment to treatment, as well as their own behaviors and reactions to their child. The aim of this cross-sectional, mixed-method study of 70 parents of adolescents receiving wraparound mental health services is to examine: (1) how parents conceptualize their child's MH problems; (2) factors related to parents' conceptualization of youths' problems using medical model terms; and (3) associations between parents' problem conceptualization and their emotional or coping responses to their child having psychiatric problem(s). Content analysis indicated that 54.3% of parents definitively conceptualized adolescents' problems using psychiatric terms, 37.1% reported uncertainty about the nature of their child's problems, and 8.6% gave alternative, non-psychiatric explanations for their child's problems. We found significant relationships between parents' problem conceptualization and their attitudes and experience with MH treatment, demographics, as well as with adolescents' clinical characteristics. Parents who conceptualized problems using psychiatric terminology were more likely to express sadness and pessimism relative to other parents, though there were no differences in expressions of worry, guilt, pragmatism and optimism by problem conceptualization.

Unveiling the mystery about adult ADHD: one woman's journey

Attention deficit hyperactivity disorder (ADHD), a neurobiological disorder, affects millions of individuals and can significantly impact an individual's life course. Research guidelines used in assessment, diagnosis, and treatment have focused primarily on Caucasian males generating, in part, the need to redress how gender and other contextual factors are considered. Consequently many women and persons from diverse cultural groups can be ignored or misdiagnosed. Undiagnosed and untreated women with ADHD are therefore limited in their potential to flourish socially, academically, interpersonally, and in their family roles. This case example of a 38-year-old African American woman illustrates how her life journey was affected by undiagnosed ADHD.
