Adolescent Outcomes of Childhood Attention-Deficit/Hyperactivity Disorder in a Diverse Community Sample

OBJECTIVE To describe adolescent outcomes of childhood attention-deficit/hyperactivity disorder (ADHD) in a diverse community sample. METHOD ADHD screening of a school district sample of 1,615 students aged 5 to 11 years was followed by a case-control study 8 years later. High-risk youths meeting full (n = 94) and subthreshold (n = 75) DSM-IV ADHD criteria were matched with demographically similar low-risk peers (n = 163). Outcomes domains included symptom, functional impairment, quality of life, substance use, educational outcomes, and juvenile justice involvement. RESULTS In all, 44% of youths with childhood ADHD had not experienced remission. Compared with unaffected peers, adolescents with childhood ADHD were more likely to display oppositional defiant disorder (odds ratio [OR] = 12.9, 95% confidence interval [CI] 5.6-30.0), anxiety/depression (OR = 10.3, 95% CI 2.7-39.3), significant functional impairment (OR = 3.4, 95% CI 1.7-6.9), reduced quality of life (OR = 2.5, 95% CI 1.3-4.7), and involvement with the juvenile justice system (OR = 3.1, 95% CI 1.0-9.1). Subthreshold ADHD, but not full ADHD, increased the risk of grade retention, whereas both conditions increased the risk of graduation failure. Oppositional defiant disorder (ODD), but not childhood ADHD, increased the risk of cannabis and alcohol use. None of the adolescent outcomes of childhood ADHD were moderated by gender, race or poverty. CONCLUSIONS ADHD heralds persistence of ADHD and comorbid symptoms into adolescence, as well as significant risks for functional impairment and juvenile justice involvement. Subthreshold ADHD symptoms typically do not qualify affected students for special educational interventions, yet increase the risk for adverse educational outcomes. Findings stress the importance of early ADHD recognition, especially its comorbid presentation with ODD, for prevention and intervention strategies.

ADHD and Conduct Disorder: An MRI Study in a Community Sample

Summary: MRI studies of children with Attention-Deficit Hyperactivity Disorder (ADHD) have consistently attributed core deficits of inattention and impulsivity to frontal-striatal-cerebellar abnormalities; however, no study has investigated the neuroanatomical characteristics of children with ADHD and Conduct Disorder (CD). This study examined a community sample of 12 children with combined subtype ADHD (aged 8-12, 7 with CD) and 19 healthy controls matched for age, gender, handedness and poverty. Volume measurements, including left/right asymmetries, were quantified from MRI of the total brain, caudate and cerebellar vermis. No significant differences in total brain volume, caudate volume, asymmetry of the hemispheres or asymmetry of the caudate were found between the groups. Measurements of the left and total posterior superior and inferior lobes of the vermis, however, indicated smaller volumes for both pure ADHD and co-morbid children compared to the controls. Analysis of variance demonstrated no significant volumetric differences between the pure ADHD and co-morbid types. Prolonged exposure to methylphenidate was associated with caudate volumes. These results suggest ADHD and ADHD co-morbid with CD have similar deviant cerebellar morphology and replicate previous studies with an epidemiologically derived sample.

Child Temperament, ADHD, and Caregiver Strain: Exploring Relationships in an Epidemiological Sample

OBJECTIVE To investigate the relationship between child-reported dimensions of temperament and attention-deficit/ hyperactivity disorder (ADHD), as well as other indicators of child psychopathology, including disruptive disorders, depression, and anxiety. It also examined whether difficult child temperament scores independently predicted caregiver strain. METHOD A school-district-wide, two-phase screening design (response rate 70% for phase 2) identified elementary school children at high risk for ADHD. Two hundred high-risk children and their parents completed standardized instruments to assess child temperament, diagnoses of disruptive disorders, childrens symptoms of anxiety and depression, and caregiver strain. Relationships were examined using analysis of variance, correlations, and multivariate prediction models, adjusting for child sociodemographic characteristics and psychopathology. All estimates were weighted for sampling design and differential participation. RESULTS Combined subtype ADHD was associated with lower scores on task orientation and higher scores on general activity level. Depressive symptoms correlated significantly with all but one difficult temperament dimension, in a pattern consistent with clinical symptoms of depression. Child temperament did not vary by ADHD treatment status. Among these high-risk children, maternal caregiver strain experiences were increased by male gender, inattention symptoms, and oppositional defiant disorder, but not by difficult temperament scores. CONCLUSION This study provides support for Graham and Stevensons hypothesis of continuity between specific temperament traits and certain child psychiatric disorders, namely ADHD and depressive disorders.

Exploring Help-Seeking for ADHD Symptoms: A Mixed-Methods Approach

Objective: Gender and race differences in treatment rates for attention‐deficit/hyperactivity disorder (ADHD) are well documented but poorly understood. Using a mixed‐methods approach, this study examines parental help‐seeking steps for elementary school students at high risk for ADHD. Methods: Parents of 259 students (male/female, African American/Caucasian) identified as being at high risk for ADHD completed diagnostic interviews and provided detailed accounts of help‐seeking activities since they first became concerned about their child. Help‐seeking steps (n=1,590) were analyzed using two methods: inductive analysis based on grounded theory, and deductive quantitative analysis of coded data derived from application of the network‐episode model, merged subsequently with demographic and other characteristics. Results: The inductive analysis revealed unique parental perceptions of their childrens sick role and of the agents of identification and intervention for each of the four groups. Deductive analysis showed significant variations by race and gender in consultation experiences, in the person or entity being consulted and in the transactions occurring in the consultation, and in illness careers. Conclusion: ADHD symptoms are interpreted as having different implications for the sick role and the intervention, dependent on a childs gender and race. Educational interventions need to address cultural stereotypes contributing to inequitable access to treatment.

Receiving Treatment for Attention-Deficit Hyperactivity Disorder: Do the Perspectives of Adolescents Matter?

PURPOSE This study describes the perspectives of parents and adolescents regarding clinical need for and attitudes toward care for attention-deficit hyperactivity disorder (ADHD). In addition, it explores as to how these views relate to past year usage of mental health services. METHODS Parents and adolescents were interviewed 6 years after the school district was screened for ADHD. Using standardized measures, mental health service usage, adolescent and parent perceived clinical needs (ADHD symptoms, disruptive behavior disorders, anxiety and/or depression, functioning), and enabling attitudes (treatment receptivity, ADHD stigma), as well as parent factors (caregiver strain, distress, instrumental social support) were assessed. Nested logistic regression modeling was used to determine the hierarchical contribution of parent and adolescent perspectives on past year service usage, after adjusting for previous usage of mental health services. Stepwise regression was conducted to identify the variables that were most predictive of service usage. RESULTS Among the adolescents who were at a high risk for ADHD, 79% had a history of lifetime mental health service usage, but only 42% had received any kind of mental health services in the past year. In hierarchical modeling, only parent inattention ratings and medication receptivity and adolescent ADHD stigma perceptions contributed significantly toward improved model fit. Stepwise regression confirmed these three variables to be predictors (OR: 1.2, 3.8, and .2, respectively) and identified adolescents-reported functioning as an additional predictor of service usage (OR: 1.1). CONCLUSION Perceptions of adolescents regarding the stigma related to ADHD are influential in treatment receipt. Quality improvement interventions for adolescents with ADHD should include psychoeducational interventions for adolescents and their parents that target medication receptivity and the stigma related to ADHD.

ADHD knowledge, perceptions, and information sources: perspectives from a community sample of adolescents and their parents.

PURPOSE The chronic illness model advocates for psychoeducation within a collaborative care model to enhance outcomes. To inform psychoeducational approaches for ADHD, this study describes parent and adolescent knowledge, perceptions, and information sources and explores how these vary by sociodemographic characteristics, ADHD risk, and past child mental health service use. METHODS Parents and adolescents were assessed 7.7 years after initial school district screening for ADHD risk. The study sample included 374 adolescents (56% high and 44% low ADHD risk) aged, on average, 15.4 (standard deviation = 1.8) years, and 36% were African American. Survey questions assessed ADHD knowledge, perceptions, and cues to action and elicited used and preferred information sources. Multiple logistic regression was used to determine potential independent predictors of ADHD knowledge. McNemar tests compared information source utilization against preference. RESULTS Despite relatively high self-rated ADHD familiarity, misperceptions among parents and adolescents were common, including a sugar etiology (25% and 27%, respectively) and medication overuse (85% and 67%, respectively). African American respondents expressed less ADHD awareness and greater belief in sugar etiology than Caucasians. Parents used a wide range of ADHD information sources, whereas adolescents relied on social network members and teachers/school. However, parents and adolescents expressed similar strong preferences for the Internet (49% and 51%, respectively) and doctor (40% and 27%, respectively) as ADHD information sources. CONCLUSIONS Culturally appropriate psychoeducational strategies are needed that combine doctor-provided ADHD information with reputable Internet sources. Despite time limitations during patient visits, both parents and teens place high priority on receiving information from their doctor.

Agreement between CASA parent reports and provider records of children's ADHD Services

This study examines agreement between parental reports of childrens ADHD outpatient services ascertained with the Child and Adolescents Services Assessment (CASA) and provider records among a sample of elementary school students who participated in an epidemiologically based health services study. Parental reports of any outpatient mental health treatment, services intensity, and medication regimens were compared to records of the specified mental health and primary care providers using intraclass correlations and kappa estimates. Results indicated that parental reports using the CASA produced valid data on whether any outpatient ADHD services had been received in the past 12 months (83% agreement), and on details of the childs medication regimens (kappas above 0.90), but that agreement was poor on how many times the child had been seen (intraclass correlation 0.29), without agreement differences by provider type. These findings support the validity of using parental report for ADHD services in primary care settings and for study of medication regimens.This study examines agreement between parental reports of childrens ADHD outpatient services ascertained with the Child and Adolescents Services Assessment (CASA) and provider records among a sample of elementary school students who participated in an epidemiologically based health services study.

Academic Outcome Trajectories of Students With ADHD Does Exceptional Education Status Matter

Attention-deficit/hyperactivity disorder (ADHD) has been associated with poor academic performance, but little is known about learning trajectories and risk factors for poor academic outcomes. This study investigates the relationship between ADHD and academic performance in students with ADHD (n = 87), students with subclinical ADHD (n = 23), and matched comparisons (n = 112), accounting for exceptional student education (ESE) status. Academic outcomes included reading and math scores on a state-mandated achievement test, the Florida Comprehensive Assessment Test (FCAT), grade point averages, retention, and graduation. Cross-sectional and longitudinal analyses were conducted, adjusting for sociodemographic characteristics and ESE, to test ADHD status as an independent outcome predictor. Students with ADHD received more special education services (53%) than subclinical (26%) and comparison (10%) students (p < .01). ADHD was associated with poorer academic performance on all outcome measures, but only when ESE status was not accounted for. In the longitudinal analysis students with ADHD and special education needs consistently achieved lower FCAT scores than peers in the comparison group but showed comparable learning gains, or slopes, over time. Students without special education needs and gifted students with ADHD had comparable achievement and learning gains as comparison students of the same ESE status. Results suggest that special education status is a driving factor in underachievement among students with ADHD.

Frequency and Correlates of Suicidal Ideation in Pediatric Obsessive–Compulsive Disorder

This study examined the frequency and sociodemographic and clinical correlates of suicidal ideation in a sample of children and adolescents with obsessive–compulsive disorder (OCD). Fifty-four youth with OCD and their parent(s) were administered the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime, Children’s Yale-Brown Obsessive Compulsive Scale, and Children’s Depression Rating Scale-Revised. Children completed the Suicidal Ideation Questionnaire-Junior (SIQ-JR), Child Obsessive Compulsive Impact Scale-Child, and Multidimensional Anxiety Scale for Children; parents completed the Child Obsessive Compulsive Impact Scale-Parent, Swanson, Nolan, and Pelham-IV Parent Scale, and Young Mania Rating Scale-Parent Version. Seven youth endorsed clinically significant levels of suicidal ideation on the SIQ-JR. Suicidal ideation was significantly related to clinician-rated depressive symptoms, age, child-rated impairment and anxiety symptoms, and symmetry, sexuality/religiosity and miscellaneous symptom dimensions. There was no significant association between suicidal ideation and obsessive–compulsive symptom severity, comorbidity patterns, or several parent-rated indices (e.g., impairment, impulsivity). These results provide initial information regarding the frequency and correlates of suicidal ideation in treatment-seeking youth with OCD. Clinical implications are discussed, as well as directions for future research.
