This community-based study used multiple informants to develop and apply a DSM -IVTR-based case definition of ADHD to screening and diagnostic interview data collected for children 5-13 years of age. Teachers screened 10,427 children (66.4%) in four school districts across two states (SC and OK). ADHD ratings by teachers and parent reports of diagnosis and medication treatment were used to stratify children into high and low risk for ADHD. Parents (n = 855) of high risk and gender frequency-matched low risk children completed structured diagnostic interviews. The case definition was applied to generate community prevalence estimates, weighted to reflect the complex sampling design. ADHD prevalence was 8.7% in SC and 10.6% in OK. The prevalence of ADHD medication use was 10.1% (SC) and 7.4% (OK). Of those medicated, 39.5% (SC) and 28.3% (OK) met the case definition. Comparison children taking medication had higher mean symptom counts than other comparison children. Our ADHD estimates are at the upper end of those from previous studies. The identification of a large proportion of comparison children taking ADHD medication suggests that our estimates may be conservative; these children were not included as cases in the case definition, although some might be effectively treated.

A random sample of youth ages 13–17 who were referred for mental health services (n=120) and not referred for services (n=120) at a juvenile detention facility were studied. Psychopathology was evaluated using the Diagnostic Interview Schedule for Children and the Child Behavior Checklist. Ninety-six percent of referred youth and 69% of non-referred youth had one or more psychiatric diagnoses. Co-morbidity was common in both groups. The findings suggest that youths in the juvenile justice system have noteworthy psychopathology that often remains unidentified.

NHIS includes 10,367 children ages 4 to 17. Parents report lifetime diagnosis of ADHD and complete the Strengths and Difficulties Questionnaire (SDQ). Prevalences of clinically significant ADHD and comorbid symptoms by race and ethnicity, gender, and age are presented. Prevalence of clinically significant SDQ ADHD symptoms is 4.19% (males) and 1.77% (females). Male prevalence by race is 3.06% for Hispanics, 4.33% for Whites, and 5.65% for Blacks. Significant differences in prevalence occur across gender (p < .01) and among males across race (p < .01), age (p < .01), and income (p < .02). In the full sample, 6.80% of males and 2.50% of females have a parent-reported lifetime ADHD diagnosis but are negative for SDQ ADHD. Likewise, 1.59% of males and 0.81% of females are positive for SDQ ADHD but negative for parent report of ADHD diagnosis. SDQ ADHD positive children have substantially higher proportions of elevated scores on other SDQ subscales. ADHD symptoms vary by race and ethnicity, gender, and age and are associated with other emotional and behavioral difficulties. Both overdiagnosis and underdiagnosis of ADHD may be issues in the U.S. population of 4- to 17-year-olds.
Attention Deficit Hyperactivity Disorder (ADHD) and Post-Traumatic Stress Disorder (PTSD) show a ... more Attention Deficit Hyperactivity Disorder (ADHD) and Post-Traumatic Stress Disorder (PTSD) show a high degree of comorbidity in traumatized children. Two hypotheses may help explain this relationship: children with ADHD are at higher risk for trauma due to their impulsivity, dangerous behaviors, and parents who may have a genetic predisposition for impairment of their own impulse control; and hyperarousal induced by severe trauma and manifested by hypervigilance and poor concentration may impair attention to create an ADHD-like syndrome. Four illustrative cases are presented, and implications for treatment are discussed.

These were all the adolescent admissions during an entire calendar year (1988). There were 101 African-American and 251 white subjects. The data were abstracted from patients' hospital medical records and nursing incident reports. DSM-III-R discharge diagnoses were assigned to five non-mutually exclusive groupings (organic/psychotic, mood/anxiety, disruptive, personality, substance abuse). Racial differences were analyzed using chi 2, logistic regression, and T statistics. African-Americans were more likely to be involuntarily committed at the time of admission (p = .010). Organic/psychotic diagnoses were much more frequent in African-Americans (odds ratio = 3.15, p < .003). Whites (p = .0347) were almost two times more likely to receive mood/anxiety diagnoses even when controlling for gender, type of admission, and comorbid diagnoses. Substance abuse was more often diagnosed in whites (odds ratio = 5.46, p < .0001). This study identifies significant racial differences in the discharge diagnoses of psychiatrically hospitalized adolescents. African-Americans have fewer mood/anxiety and substance abuse diagnoses but significantly more organic/psychotic diagnoses. Some of these differences may reflect ethnocentric clinician bias in the diagnostic assessment of youth from differing cultural/racial backgrounds.

We examined suicide rates among 4 age groups from 1970 to 2002 and the factors that may have contributed to the decline. We paid particular attention to newer anti-depressants because of recent concerns and controversy about a possible association with suicidal behaviors. These trends warrant more extensive analysis of suicide rates among specific subgroups, including consideration of additional variables that may influence rates differentially. The relative contributions of depression diagnosis and treatment, postsuicide attempt care, and other contextual factors (e.g., overall economic conditions) also deserve attention. If the decline is associated with contextual factors, clarifying these associations will better inform public policy decisions and contribute to more effective interventions for preventing suicide.

Evidence suggests that race is a factor in the referral of children for treatment. This study examines race and gender differences in treatment of adolescent psychiatric disorders. During a two-stage, school-based, epidemiological study of depression, data were collected on 478 adolescents. Instruments included the Schedule for Affective Disorders and Schizophrenia for School-Age Children and the Children's Global Assessment Scale. Twenty-two percent of the sample had contact with professionals during the prior year, including 56% of adolescents with a psychiatric diagnosis. Significant odds ratios (ORs) were found between all diagnoses and treatment. Trends for undertreatment of females and African-Americans were evident in univariable and multivariable models. The OR (0.34) for African-American females was significant in the multivariable model. African-Americans were significantly more likely to receive only one or two treatment contacts. Data suggest race and gender differences in the treatment of adolescent psychiatric disorders. Possible explanations include referral bias, low cultural competence of mental health professionals, and cultural differences in the expression and tolerance of symptoms and help-seeking behaviors. Further study of factors influencing treatment decisions is needed.

Prevalence estimates of interview validated nonsuicidal physically self-damaging acts were 2.46% in males and 2.79% in females. Significant relationships were found between nonsuicidal physically self-damaging acts and suicidal ideation, major depression and undesirable life events. Data suggest that physically self-damaging acts occur at substantial rates during early adolescence. The strong correlation between nonsuicidal self-destructive acts and both suicidal ideation and major depression clarifies prior conflicting reports in the literature and suggests that a history of self-damaging acts should be taken into consideration when evaluating for possible depression and suicide risk.

Based on the Center for Epidemiologic Studies Depression Scale scores, a stratified sample of middle-school students was interviewed using the Schedule for Affective Disorders and Schizophrenia for School-Aged Children: cycle one (n = 579; mean age 12.83) and cycle two (n = 490; mean age 18.65). Service use also was assessed by mailed questionnaire: cycle three (n = 330; mean age 20.60). Service use decreased over time. Whites and males received significantly more treatment in the first cycle. In the second cycle, service use by race and gender was equal; in the third cycle, females received more treatment. Those with a psychiatric diagnosis (first cycle 54%; second cycle, 33%) received treatment in the prior year. Under-treatment of youth with psychiatric diagnoses is a significant problem, with differences in service use by race and gender over time.

A two-stage epidemiological study originally designed to investigate adolescent depression was conducted between 1986 and 1988 in the southeastern United States. In the first stage, a self-report depressive symptom questionnaire was administered to a community sample of 3,283 adolescents. In the diagnostic stage, the Schedule for Affective Disorders and Schizophrenia for School-Age Children and the Children's Global Assessment Scale were administered to 487 mother-child pairs. Prevalence rates of clinical, subsyndromal, and subthreshold phobia were 2.3%, 14.5%, and 22.2%, respectively. One-year incidence rates were 0.4%, 8.0%, and 16.9%, with 43.0% of phobic subjects categorized at the same or a more severe level after a year. Females, blacks, subjects not living with both biological parents, and older adolescents were more likely to meet the diagnostic criteria for clinical phobia. The majority (77%) of subjects with clinical phobia experienced multiple phobias. Subsyndromal (52%) and subthreshold (74%) phobics were more likely to experience simple phobias only. Phobic symptoms are relatively common at a moderate level and in the majority of adolescents are somewhat transitory in nature. Characteristic symptomatology and comorbidity may facilitate earlier identification of subjects at risk of persistent symptomatology and in need of treatment.

Adolescents from a two-stage, community-based longitudinal study were classified into suicidal behavior categories (attempt, plan, ideation, and none) for baseline and follow-up years. Transition probabilities for movement among categories were calculated, and polytomous logistic regression analysis was used to examine predictors of suicidal behaviors. Among those with no suicidal behaviors at baseline, 1-year incidence rates were 1.3% for attempts and 1.7% each for plans and ideation. Increasing family cohesion was protective for suicide attempts (odds ratio [OR] = 0.9). Female subjects were more likely than males to report plans (OR = 8.9) and ideation (OR = 4.1). Increasing impulsivity (OR = 2.3), prior suicidal behavior (OR = 10.6), and undesirable life events (OR = 1.1) were significant predictors of plans. While there are a number of predictors of suicidal behaviors, the false-positive rate is high. Focusing on proximal risk factors, particularly stressors in adolescent development, may overlook the fundamental role of underlying mental disorder and familial factors--both biological and environmental. Suicide and suicidal behaviors are the result of a constellation of adverse factors requiring a range of interventions for prevention.

The 2001 National Health Interview Survey (NHIS) contained the Strengths and Difficulties Questionnaire (SDQ; used to determine probable ADHD), data on medical problems, overall health, and health care utilization. Asthma was two and headaches were three times more prevalent, and overall health was significantly lower, among children with SDQ ADHD. Of children with SDQ ADHD, 45% saw a mental health professional in the past year and over half were not taking medication regularly. Urban residence, age (9-13), higher family education, having health insurance, and having comorbid emotional problems were associated with mental health care utilization in children with SDQ AD/HD, while race, gender and family income were not associated. Children with SDQ AD/HD had more medical problems and were more likely to visit the emergency room. Treatment data suggest a problem with under-treatment of ADHD in the United States. Interventions should be targeted in rural areas, and among families with low education and without health insurance.
