ADHD in children and young people: prevalence, care pathways, and service provision. Lancet Psychiatry 2018; 5:175-186. [PMID: 29033005 DOI: 10.1016/s2215-0366(17)30167-0] [Citation(s) in RCA: 516] [Impact Index Per Article: 86.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2016] [Revised: 03/30/2017] [Accepted: 03/30/2017] [Indexed: 12/17/2022]
Abstract
Attention-deficit hyperactivity disorder (ADHD) is a common childhood behavioural disorder. Systematic reviews indicate that the community prevalence globally is between 2% and 7%, with an average of around 5%. At least a further 5% of children have substantial difficulties with overactivity, inattention, and impulsivity that are just under the threshold to meet full diagnostic criteria for ADHD. Estimates of the administrative prevalence (clinically diagnosed or recorded) vary worldwide, and have been increasing over time. However, ADHD is still relatively under-recognised and underdiagnosed in most countries, particularly in girls and older children. ADHD often persists into adulthood and is a risk factor for other mental health disorders and negative outcomes, including educational underachievement, difficulties with employment and relationships, and criminality. The timely recognition and treatment of children with ADHD-type difficulties provides an opportunity to improve long-term outcomes. This Review includes a systematic review of the community and administrative prevalence of ADHD in children and adolescents, an overview of barriers to accessing care, a description of associated costs, and a discussion of evidence-based pathways for the delivery of clinical care, including a focus on key issues for two specific age groups-younger children (aged ≤6 years) and adolescents requiring transition of care from child to adult services.

Abstract
OBJECTIVE To examine dispensing patterns of methylphenidate (MPH) to determine how socioeconomic status (SES), ethnocultural affiliation, and gender affect the medical treatment of ADHD. METHOD We reviewed MPH prescription records for year 2011 of children aged 6 to 18, from regional pharmacies serving homogeneous neighborhoods. RESULTS MPH prescriptions showed an increase in prevalence from 4.2% to 7.5% in the years 2007 to 2011, respectively. Jewish children were four times more likely to be prescribed MPH than Arab children, with significant discrepancies along SES and gender lines ( p < .001). Higher SES and male gender were associated with greater use of MPH. General pediatric prescription rates of MPH in all communities increased by 85%, compared with year 2007 statistics ( p < .001). CONCLUSION Prescription patterns for MPH in children reflect diagnostic patterns of ADHD that appear to be heavily influenced by additive factors of SES, cultural attitudes, and gender. Dispensing data provide valuable information for targeting underserved groups and defining potential areas of abuse.

Abstract
OBJECTIVE There is a need for Australian studies of ADHD that utilize the individual child as the unit of analysis because they provide a more accurate picture of national patterns (in new prescriptions, start age, and duration). The aim of this study was to build toward a national picture of patterns in psychostimulant use for ADHD by undertaking a retrospective analysis of archival data on prescriptions within New South Wales (NSW), Australia's most populated state. METHOD A person-based data set was used to assess (a) rate of new prescriptions by age group, (b) demographic characteristics (age of start, male:female ratio), (c) duration of use, and (d) comparisons across the two decades. RESULTS Five findings were observed: (a) The prevalence of psychostimulant use was 1.24% in 2010, (b) there was significant variability in the rate of new prescriptions by age group after 2003, (c) start age declined over the 1990 to 2000 period, but began to increase from 2000 to 2010, (d) the male:female ratio declined, and (e) the duration of psychostimulant use declined consistently. CONCLUSION Results suggest disconnect between persistence across the life span and actual treatment patterns. A decline in medication treatment for more than 1 year and the growing proportion of discontinuous treatment suggests a need for strategies to assist families with the transition onto and off medications.

Abstract
OBJECTIVE To explore correspondences between the trajectories of symptoms and impairments in youth with attention-deficit hyperactivity disorder (ADHD) being treated by in primary care settings. METHODS Parents of youth (n = 1976) rated their child's symptoms of inattention and hyperactivity/impulsivity, and impairment across a variety of domains. Multilevel models were estimated to characterize the trajectories of symptoms and impairment and to determine whether changes in symptom dimension trajectories corresponded to changes in impairment trajectories over time. RESULTS Results indicated that symptom dimensions initially improved, then leveled off, and then decreased minimally. However, impairment domains remained largely stable (i.e., neither improved nor worsened). Improvement in inattention symptoms were associated with improved ratings of writing impairment, and improved ratings of hyperactivity/impulsivity symptoms were associated with improved relationship with peers. CONCLUSIONS Youths with ADHD who are treated by their community pediatrician tend to initially improve in their symptom presentation, although this symptom reduction plateaus and is not associated with corresponding improvements in most areas of impairment.

Abstract
This paper analyzes local and regional geographic variability in the use of antidepressant, antipsychotic and stimulant medications in the United States. Using a data set that covers 60% of prescriptions written in the United States, we find that use of antidepressants in three digit postal codes ranged from less than 1% of residents to more than 40% residents. Stimulant and antipsychotic use exhibited similar levels of local geographic variability. A Kulldorf Spatial Scan identified clusters of elevated use of antidepressants (RR 1.46; p<0.001), antipsychotics (RR 1.42; p<0.001), and stimulants (RR 1.77; p<0.001). Using a multilevel model, we find that access to health care, insurance coverage and pharmaceutical marketing efforts explain much of the geographic variation in use.

Abstract
OBJECTIVE To evaluate the clinical utility of the cutoff recommendations for the Vanderbilt ADHD Diagnostic Parent Rating Scale (VADPRS) comorbidity screening scales provided by the American Academy of Pediatrics/National Initiative for Children's Healthcare Quality and to examine alternative cutoff strategies for identifying and ruling out disorders commonly comorbid with attention-deficit/hyperactivity disorder. METHODS A sample of 215 children (142 with attention-deficit/hyperactivity disorder), ages 7 to 11 years, participated in the study. Parents completed the VADPRS and were administered a diagnostic interview to establish diagnoses of oppositional defiant disorder (ODD), conduct disorder (CD), anxiety, and depression. The clinical utility of the VADPRS comorbidity screening scales were examined. RESULTS The recommended American Academy of Pediatrics/National Initiative for Children's Healthcare Quality cutoff strategies did not have adequate clinical utility for identifying or ruling out comorbidities, with the exception of the VADPRS ODD cutoff strategy, which reached adequate levels for ruling out a diagnosis of ODD. An alternative cutoff approach using total sum scores was superior to the recommended cutoff strategies across all diagnoses in terms of ruling out a diagnosis, and this was particularly evident for anxiety/depression. Several individual items on the ODD and CD scales also had acceptable clinical utility for ruling in diagnoses. CONCLUSIONS The VADPRS comorbidity screening scales may be helpful in determining which children likely do not meet diagnostic criteria for ODD, CD, anxiety, or depression. This study suggests that using a total sum score provides the greatest clinical utility for each of these comorbidities and demonstrates the need for further research examining the use of dimensional assessment strategies in diagnostic decision making.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a common neurobehavioral condition that impairs functioning throughout childhood and adolescence. Evidence-based guidelines for the treatment of ADHD recommend recognizing ADHD as a chronic condition. The chronic care model for child health emphasizes the need for productive interactions between an informed, activated family and a prepared, proactive practice team. Key parent-physician interactions in the treatment of a child with ADHD include: family education, treatment goal setting, treatment plan formation, cardiovascular screening, medication titration and ongoing monitoring and treatment plan revision. Most care for children/adolescents with ADHD is provided in community-based primary care settings where there are significant barriers to delivering high-quality care to children with chronic conditions. This article reviews recommended physician-parent interactions, examines current practice patterns and identifies facilitators and barriers to the implementation of recommended practices for ADHD care.

Abstract
PURPOSE Although much literature reports small-area variation in medication prescriptions used to treat attention-deficit hyperactivity disorder (ADHD), scant research has examined factors that may drive this variation. We examine, across counties in the USA, whether the use of prescription medications to treat ADHD varies positively with supply-side healthcare characteristics. METHODS We retrieved annual prescription data for ADHD medications in 2734 US counties from a nationally representative sample of 35 000 pharmacies in 2001-2003. We used a county-level, multivariable fixed effects analysis to estimate the relation between annual changes in healthcare supply and ADHD medication prescriptions. Methods controlled for time-invariant factors unique to each county as well as ADHD prevalence. RESULTS From 2001 to 2003, retail prescription purchases for ADHD medications increased 33.2%. In the multivariable analysis, ADHD medication prescriptions move positively with an increase in the concentration of total physicians. In addition, ADHD medication prescriptions move inversely with changes in the percentage of non-Hispanic Black population. CONCLUSIONS Supply-side healthcare factors may contribute to the rise from 2001 to 2003 in ADHD medication prescriptions. This finding warrants attention because it implies that the relative capacity of the healthcare system may influence population prescription rates. We encourage further exploration of the contribution of the supply-side of the healthcare market to secular changes in ADHD medication prescriptions.

Abstract
OBJECTIVE To perform a novel geographic analysis of Attention-Deficit/ Hyperactivity Disorder (ADHD) diagnosis in Midwest United States. METHOD Primary care children age 5-17 with ADHD diagnosis (N = 6833; 13.5%) were compared to those receiving well child care without ADHD diagnosis (N = 43,630) in a Wisconsin integrated medical system. Street addresses, demographic, and block group level U.S. Census 2000 data were mapped and analyzed using ArcGIS, CrimeStat III, and SaTScan. Lead levels from a State database were linked to 2,837 subjects. Univariate analysis was done by chi-square test or Mann-Whitney U test, multivariate analysis by logistic regression. RESULTS ADHD cases were 74% male (p = 0.0001), and more frequently diagnosed in White children (17.3%) than Blacks (10.6%), Hispanics (9.4%), or Asians (3.7%; all p values < 0.001). Overall, male gender, white race, lower block group median household income and population density, and greater distance to nearest park and airport were more predictive of ADHD (p values < 0.001). In urban Milwaukee County (865 cases/10,493 controls) male gender, white race, suburban residence, and younger age were more predictive of ADHD (p values < 0.01). Among children with ADHD diagnosis and linked lifetime lead values, those with a maximum level of 10 microg/dl or more differed significantly from controls (9.3% vs. 5.6%; p = 0.003); elevated lead remained a significant predictor of ADHD diagnosis in multivariate analysis. CONCLUSIONS Further studies are needed to determine if geographic distribution of ADHD diagnosis can be partially explained by differential efficiency of referral for diagnosis by school districts, by race/ethnicity, and/or built environment.

Abstract
OBJECTIVE The goal was to examine the clinical utility of using the Vanderbilt Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale (VARS) to determine when to refer children with ADHD for learning disorder (LD) evaluations. METHODS A total of 128 stimulant-naive children with ADHD, 7 to 11 years of age, were included in the study. The parents and teachers of 128 children with diagnosed ADHD completed the VARS. The reading, numerical operations, and spelling subtests from the Wechsler Individual Achievement Test, Second Edition, were used to identify children with a comorbid LD. We examined the predictive validity and clinical utility of the VARS performance items for ruling in/out the presence of a comorbid LD. RESULTS Thirty-eight percent of the samples met the criteria for a comorbid LD. A cutoff score of 7.5 for the sum of the VARS parent and teacher reading items had excellent clinical utility for ruling out both reading and spelling LDs. Cutoff scores of 4 for the VARS teacher reading and writing items had excellent utility for ruling out comorbid reading and spelling LDs, respectively. None of the VARS performance items effectively identified or ruled out math LDs. CONCLUSION The VARS performance items should be used with an interview about school functioning and a review of school records to rule out the presence of a comorbid reading or spelling LD for children with diagnosed ADHD.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a commonly occurring behavioral disorder among children. Community-based physicians are often the primary providers of services for children with ADHD. A set of consensus guidelines has been published by the American Academy of Pediatrics that provides best-practice diagnostic procedures for primary-care physicians. These recommendations emphasize the importance of using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria as the basis for making an ADHD diagnosis and conducting systematic follow-up, including the collection of parent and teacher ratings scales to quantitatively assess response to treatment. Although these recommendations have been widely disseminated and their adoption actively promoted, guideline adherence, in general, is known to be poor. Two types of intervention models, ancillary service and office systems modification, have been proposed to promote adoption of evidence-based ADHD practice in primary-care settings. The present article reviews the efficacy of these intervention models, and discusses the cost and sustainability of each model as related to feasibility of intervention dissemination.

Abstract
OBJECTIVE The aim of the present study was to undertake a retrospective analysis of archival data on psychostimulant prescriptions from South Australia for the periods 1990-2000 and 2001-2006 for 7849 youths aged from birth to 18 years. METHOD A person-based data set was used to assess: (i) rate of new prescriptions by age group; (ii) demographic characteristics (age of psychostimulant start, male: female ratio); (iii) duration of psychostimulant use; and (iv) geographic variation in psychostimulant prescription. RESULTS Four major findings were observed: (i) the rate of new prescriptions was highly variable both for 1990-2000 and 2000-2006; (ii) demographic characteristics such as start age and male:female ratio declined over both periods; (iii) the duration of psychostimulant use was approximately 2.5 years for 1990-2000 and 2.0 years for 2000-2006; and (iv) there was geographic variation in both periods with a significant correlation between socioeconomic status and prescription rate per region. CONCLUSIONS The patterns of psychostimulant use in Australia closely parallel the USA. Physicians' prescribing practice may be extremely volatile. Duration of psychostimulant treatment should receive increased attention. There is pronounced geographic variability in prescription rates, which may be related to socioeconomic status.

Abstract
The Hastings Center, a bioethics research institute, is holding a series of 5 workshops to examine the controversies surrounding the use of medication to treat emotional and behavioral disturbances in children. These workshops bring together clinicians, researchers, scholars, and advocates with diverse perspectives and from diverse fields. Our first commentary in CAPMH, which grew out of our first workshop, explained our method and explored the controversies in general. This commentary, which grows out of our second workshop, explains why informed people can disagree about ADHD diagnosis and treatment. Based on what workshop participants said and our understanding of the literature, we make 8 points. (1) The ADHD label is based on the interpretation of a heterogeneous set of symptoms that cause impairment. (2) Because symptoms and impairments are dimensional, there is an inevitable "zone of ambiguity," which reasonable people will interpret differently. (3) Many other variables, from different systems and tools of diagnosis to different parenting styles and expectations, also help explain why behaviors associated with ADHD can be interpreted differently. (4) Because people hold competing views about the proper goals of psychiatry and parenting, some people will be more, and others less, concerned about treating children in the zone of ambiguity. (5) To recognize that nature has written no bright line between impaired and unimpaired children, and that it is the responsibility of humans to choose who should receive a diagnosis, does not diminish the significance of ADHD. (6) Once ADHD is diagnosed, the facts surrounding the most effective treatment are complicated and incomplete; contrary to some popular wisdom, behavioral treatments, alone or in combination with low doses of medication, can be effective in the long-term reduction of core ADHD symptoms and at improving many aspects of overall functioning. (7) Especially when a child occupies the zone of ambiguity, different people will emphasize different values embedded in the pharmacological and behavioral approaches. (8) Truly informed decision-making requires that parents (and to the extent they are able, children) have some sense of the complicated and incomplete facts regarding the diagnosis and treatment of ADHD.

Abstract
OBJECTIVES The goals were to implement and to test a quality-improvement intervention aimed at improving community-based primary care providers' adherence to the American Academy of Pediatrics, evidence-based diagnostic and treatment guidelines for attention-deficit/hyperactivity disorder. METHODS Nineteen practices (with 84 primary care providers) from a large urban community were trained by using quality-improvement methods with some academic detailing. Pretraining and posttraining adherence to evidence-based practices was assessed through review of patient charts. RESULTS Preintervention rates of guideline usage were uniformly low. After the intervention, primary care providers showed substantial improvement in their use of the guidelines for the assessment and treatment of elementary school-aged patients with newly diagnosed attention-deficit/hyperactivity disorder. Use of parent and teacher assessment rating scales increased from levels of 52% to 55% to levels of nearly 100%. Systematic monitoring of responses to medication improved from a baseline level of 9% to 40%. CONCLUSIONS Quality-improvement interventions such as the one used in this study seem quite effective in improving primary care providers' practices at offices that express interest in improving the quality of care for attention-deficit/hyperactivity disorder. The design of the intervention, problems associated with improving and sustaining treatment monitoring, and issues related to generalizability of the intervention model are discussed.

Abstract
OBJECTIVE We used population-based administrative prescription medication data to examine regional differences in psychostimulant and antidepressant (AD) use among children from 2 Canadian provinces: British Columbia (BC) and Manitoba (MB). METHOD Using 1997 to 2003 prescription data, annual rates of psychostimulant and AD use were determined for children aged 19 years and under in both provinces. Further comparisons of rates were made according to sex, age group, and specific classes of dispensed medications. RESULTS During 1997 to 2003, psychostimulant use rose by 44.9% in MB and 13.3% in BC. Among male children, psychostimulant use increased by 40.2% in MB, compared with an increase of only 8.6% in BC. AD utilization was similar between provinces, with increases of 80% and 75% in MB and BC, respectively. In both provinces, AD use was highest among older children. CONCLUSIONS Our observations of regional variation in psychotropic medication use potentially reflect provincial differences in drug benefit policies, disease prevalence, and (or) physician diagnosis and treatment.

Abstract
OBJECTIVE This study was designed to investigate the perceptions of primary care providers about their roles and the challenges of managing attention-deficit/hyperactivity disorder and to evaluate differences between providers who serve families primarily from urban versus suburban settings. METHODS The ADHD Questionnaire was developed to assess primary care provider views about the extent to which clinical activities that are involved in the management of attention-deficit/hyperactivity disorder are appropriate and feasible in primary care. Participants were asked to rate each of 24 items of the questionnaire twice: first to indicate the appropriateness of the activity given sufficient time and resources and second to indicate feasibility in their actual practice. Informants used a 4-point scale to rate each item for appropriateness and feasibility. RESULTS An exploratory factor analysis of primary care provider ratings of the appropriateness of clinical activities for managing attention-deficit/hyperactivity disorder identified 4 factors of clinical practice: factor 1, assessing attention-deficit/hyperactivity disorder; factor 2, providing mental health care; factor 3, recommending and monitoring approved medications; and factor 4, recommending nonapproved medications. On a 4-point scale (1 = not appropriate to 4 = very appropriate), mean ratings for items on factor 1, factor 2, and factor 3 were high, indicating that the corresponding domains of practice were viewed as highly appropriate. Feasibility challenges were identified on all factors, but particularly factors 1 and 2. A significant interaction effect, indicating differences between appropriateness and feasibility as a function of setting (urban versus suburban), was identified on factor 1. The challenges of assessing attention-deficit/hyperactivity disorder were greater for urban than for suburban primary care providers. CONCLUSIONS Primary care providers believe that it is highly appropriate for them to have a role in the management of attention-deficit/hyperactivity disorder. Feasibility issues were particularly salient related to assessing attention-deficit/hyperactivity disorder and providing mental health care. The findings highlight the need not only for additional training of primary care providers but also for practice-based resources to assist with school communication and collaboration with mental health agencies, especially in urban practices.

Abstract
OBJECTIVE To review what is currently known about service use by youth with attention-deficit/hyperactivity disorder (ADHD) and discuss research and policy implications. METHODS Literature review. RESULTS The primary care, mental health, and educational service system sectors all play an essential role in caring for youth with ADHD. Recent studies also suggest increasing use of stimulants and other psychoactive medication for youth with ADHD, decreasing mental health visits for ADHD unassociated with medication use, increased use of other psychotropic medications, and a number of barriers to care coordination across primary care, mental health, and schools. CONCLUSIONS Four important services, research, and policy areas that need to be addressed over the next decade include: 1) delving deeper into current service use, 2) paying attention to the context in which service use occurs, 3) operationalizing evidence-based care for real-world settings, and 4) learning what changes clinician and educator behavior.

Abstract
OBJECTIVE Accurate assessment of racial disparities in attention-deficit/hyperactivity disorder (ADHD) depends on measurement that is equally valid for all groups. This study examines differences among African American and white children in ADHD measurement with a widely used parental report instrument, the Diagnostic Interview Schedule for Children (DISC). METHODS Data come from 1070 children in the Fast Track Project, a longitudinal study of predominantly low-income children at risk of emotional and/or behavioral problems. Item Response Theory (IRT) methodology is used to determine whether ADHD screening items provide comparable information for African American and white children or whether differential item function (DIF) exists. IRT scores and race/ethnicity are entered in logistic regression models predicting use of ADHD medication. RESULTS Seven of 39 DISC items performed differently among African Americans and whites. In most cases, parents of white children were more likely to endorse these items than were parents of African American children at comparable underlying levels of children's hyperactivity. When items exhibiting differential functioning were deleted, race disparities predicting underlying need as indicated by ADHD medication use decreased and were no longer statistically significant. CONCLUSIONS Perceptions of ADHD-related symptoms among parents of African American children appear to differ in important ways from those of parents of white children, and screening instruments relying on parent report may yield different results for African American and white children with similar underlying treatment needs. Gathering information from additional sources including teachers and school counselors can provide a more complete picture of the behavioral functioning and therapeutic needs of children in all race/ethnic groups.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a prevalent chronic condition that affects people of all ages, including young children, school-aged children, adolescents, and adults. Symptoms can be noted as early as preschool age, tend to progress into functional impairment and behavioral problems in later childhood, and typically persist into adulthood. Contrary to previous belief, the disorder does not resolve with puberty for the majority of children; rather, the symptoms are manifested differently throughout the lifecycle. Presentation in adults is heavily biased toward inattentive symptoms, which are less likely to draw notice than hyperactive or impulsive symptoms and may contribute to the underrecognition of ADHD in this patient population. Diagnosis is particularly difficult due in large part to the pronounced comorbidity of psychiatric disorders in this patient population. Identification may be even more difficult in adults than children as the diagnostic criteria are not as clear, adults have difficulty remembering symptoms prior to 7 years of age, and there is a high prevalence of comorbid psychiatric disorders in adults. Early identification and treatment of symptoms of ADHD in preschool-age children is essential to effective long-term management of the disorder. Both medication and behavioral treatments appear to alleviate the symptoms of ADHD, and evidence suggests that discontinuation of treatment leads to the reemergence of the condition. Efforts are currently continuing toward understanding the genetic underpinnings of ADHD. This expert review supplement will address the prevalence, comorbidity, treatment issues, and special considerations surrounding ADHD management throughout each stage of the lifecycle beginning with ADHD in preschool-aged children, continuing with school-aged children and adolescents, and ending with adulthood.

Abstract
OBJECTIVE To describe the rationale and design of the Preschool ADHD Treatment Study (PATS). METHOD PATS was a National Institutes of Mental Health-funded, multicenter, randomized, efficacy trial designed to evaluate the short-term (5 weeks) efficacy and long-term (40 weeks) safety of methylphenidate (MPH) in preschoolers with attention-deficit/hyperactivity disorder (ADHD). Three hundred three subjects ages 3 to 5.5 years old who met criteria for a primary DSM-IV diagnosis of ADHD entered the trial. Subjects participated in an 8-phase, 70-week trial that included screening, parent training, baseline, open-label safety lead-in, double-blind crossover titration, double-blind parallel efficacy, open-label maintenance, and double-blind discontinuation. Medication response was assessed during the crossover titration phase using a combination of parent and teacher ratings. Special ethical considerations throughout the trial warranted a number of design changes. RESULTS This report describes the design of this trial, the rationale for reevaluation and modification of the design, and the methods used to conduct the trial. CONCLUSIONS The PATS adds to a limited literature and improves our understanding of the safety and efficacy of MPH in the treatment of preschoolers with ADHD, but changes in the design and problems in implementation of this study impose some specific limitations that need to be addressed in future studies.

Abstract
OBJECTIVE To examine socioeconomic, demographic, and behavioural factors that influence the incidence of methylphenidate use among children aged 4 to 13 years. METHOD A total of 11,316 children, aged 2 through 11 years, from Cycle 1 (1994-95) of the National Longitudinal Survey of Children and Youth were followed up 2 years later in Cycle 2 (1996-97). The outcome measure was methylphenidate use in Cycle 2. Individual-level explanatory variables included sex, age, socioeconomic status (SES), mother's age at birth of child, lone-parent family status, parental working status, and hyperactivity-impulsivity and inattention probabilities. Area-level explanatory variables included income and rural or urban residence. We used hierarchical linear modelling to examine individual- and area-level factors that predicted methylphenidate use. RESULTS The strongest predictors of methylphenidate use were behavioural: children with high hyperactive-impulsive and (or) inattention behaviours in 1994, compared with children low on these behaviours, were 4.5 to 6 times more likely to use methylphenidate 2 years later. SES remained a significant predictor of the incidence of methylphenidate use, even when other significant predictors were held constant, with lower SES being associated with higher use. Area-level income also predicted methylphenidate use. CONCLUSION Even when children with similar behavioural symptoms and demographic characteristics were compared, socioeconomic factors had a significant impact on incidence of methylphenidate use.

Abstract
OBJECTIVE To determine treatment patterns for youth attention-deficit/hyperactivity disorder (ADHD) symptoms in a general population sample of 1,610 twins. METHOD Twin pairs ages 7 to 17 years and parents ascertained from birth records in the state of Missouri were interviewed using the Missouri Assessment of Genetics Interview for Children between 1996 and 2001. Multivariate logistic regression analyses were used to determine which factors were significant in answering three questions about treatment for ADHD. RESULTS Of 302 boys, 177 (58.6%) and 26 of 57 girls (45.6%) who met full DSM-IV criteria for ADHD received stimulant medication in this sample. Of 314 youths, 111 (35.4%) who received stimulant medication did not meet DSM-IV criteria for ADHD. When controlling for comorbidity and other factors, the number of impairing ADHD symptoms and having a cotwin who was also brought to treatment for ADHD correlated with referral or treatment in youths without ADHD. Youths without ADHD who were treated had a large number of ADHD symptoms. CONCLUSION As is shown in earlier studies, children with ADHD are being undertreated. Complex factors, including comorbid disorders and family history of ADHD treatment, affect treatment patterns in the general population.

Abstract
OBJECTIVES This study aimed to estimate the prevalence of methylphenidate (MPH) use among Canadian children aged 2 to 11 years, from 1994-1995 to 1998-1999 and to identify sociodemographic, child, and parent-family correlates are identified. METHODS Cross-sectional data collections from the National Longitudinal Survey of Children and Youth (NLSCY) for 1994-1995, 1996-1997, and 1998-1999 were used and samples weighted up to population levels (n=17,814 in 1994-1995, 13,575 in 1996-1997, and 18,980 in 1998-1999). Logistic regression identified correlates of parent-reported MPH use in each time period. RESULTS MPH use by Canadian children increased from 1.33% (95% confidence interval [CI], 1.17% to 1.50%) in 1994-1995 to 1.60% (95% CI, 1.42% to 1.78%) in 1998-1999. Use among school children aged 6 to 11 years increased from 1.94% (95% CI, 1.68% to 2.20%) in 1994-1995 to 2.42% (95% CI, 2.14% to 2.71%) in 1998-1999. Use of MPH increased among girls, from 0.52% (95% CI, 0.32% to 0.67%) in 1994-1995 to 0.97% (95% CI, 0.77% to 1.17%) in 1998-1999. For a child with parent-reported hyperactivity, the odds ratios for using MPH were 6.30 (95% CI, 4.94 to 8.90) in 1994-1995 and 12.54 (95% CI, 9.74 to 16.16) in 1998-1999. Age 6 to 11 years, male sex, and absence of parental alcohol use were significant correlates of MPH use in all time periods. Parental smoking correlated with MPH use in 1994-1995 and in 1998-1999. CONCLUSIONS Less than 2% of Canadian children used MPH between 1994 and 1999. Some increase in use occurred among school-aged children and girls. Parent-reported hyperactivity was the most important correlate of MPH use.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is the most common mental disorder in childhood, and primary care clinicians provide a major component of the care for children with ADHD. However, because of limited available evidence, the American Academy of Pediatrics guidelines did not include adolescents and young adults. Contrary to previous beliefs, it has become clear that, in most cases, ADHD does not resolve once children enter puberty. This article reviews the current evidence about the diagnosis and treatment of adolescents and young adults with ADHD and describes how the information informs practice. It describes some of the unique characteristics observed among adolescents, as well as how the core symptoms change with maturity. The diagnostic process is discussed, as well as approaches to the care of adolescents to improve adherences. Both psychosocial and pharmacologic interventions are reviewed, and there is a discussion of these patients' transition into young adulthood. The article also indicates that research is needed to identify the unique adolescent characteristics of ADHD and effective psychosocial and pharmacologic treatments.

Abstract
The increased use of stimulant medications for children and teenagers is an ongoing issue of professional and public concern. Unlike methylphenidate, the growth of prescriptions and patterns of utilization of amphetamines for pediatric populations have not been well documented. The study objectives were to describe the trends of amphetamine prescription utilization among pediatric age groups in Michigan and to compare area variations. A population-based computerized data set from the state of Michigan was used to extract all outpatient prescriptions for Schedule II amphetamines dispensed from 1990 to 1997. The prescribing rates by age groups and by counties were computed with the projected population size of corresponding years, and mapped and analyzed with spatial statistical methods. Counties that did not conform to the global spatial dependence pattern in the prescription rate were identified using Moran scatter plot. A total of 236,661 outpatient prescriptions for amphetamines were dispensed in Michigan during the time frame, including less than 1% for methamphetamine, 24.5% for amphetamine, and 74.8% for dextroamphetamine. The prescribing rate was highest among children 10-14 years old (380 prescriptions per 10,000 people) in 1997, followed by children 5-9 years old (253 prescriptions per 10,000). Over the 8-year period, the prescribing rates of amphetamines increased significantly, ranging from 380% for children 2-4 years to 817% for teenagers older than 14 years. The rates among counties ranged from 60 to 1648 per 10,000 children 5-14 years old, with the highest prescribing rates in the northwestern regions of Michigan. Although spatial dependence explained 36% of the variance, the area variations that are unaccounted for are still considerable. In conclusion, there were substantial increases and unexplained area variations in amphetamine usage in Michigan during the study period. Both phenomena require awareness and evaluation from researchers, policy makers, clinicians, and the public.

Abstract
OBJECTIVES To determine methylphenidate use in children aged 2 to 13 years. To provide age- and sex-specific estimates of methylphenidate initiation and cessation during a 2-year period. METHOD Data from 2 cycles of a Canadian household survey yielded a sample of over 10 000 children aged 2 to 11 years at Cycle 1 who continued to participate at Cycle 2. We used logit modelling to estimate Cycle 2 methylphenidate use, methylphenidate use over a 2-year period, and methylphenidate initiation and cessation from Cycles 1 to 2. RESULTS In 1996 and 1997, methylphenidate use ranged from 0.32% to 6.31% among children aged 4 to 13 years. School-aged boys were more likely than girls to use methylphenidate. Odds were greater for boys aged 6 to 7 years than for boys aged 4 to 5 years; they were also greater for boys aged 10 to 11 years than for boys aged 12 to 13 years. Almost 1% of children used methylphenidate at both data cycles. Odds of Cycle 2 methylphenidate use were 135 times greater for children using methylphenidate at Cycle 1, compared with nonusers. Methylphenidate initiation ranged from 0.20% to 3.34%, and school-aged boys had higher initiation rates than girls. Cessation rates ranged from 18% to78%, and there were no statistically significant differences by age and sex. CONCLUSIONS Methylphenidate prevalence findings are consistent with past studies. We found an age-by-sex interaction on methylphenidate use. We also found both continuity and discontinuity in methylphenidate use.

Abstract
OBJECTIVE The aim of this study was to examine the use of stimulants among youths in a large and diverse health plan in California from 1996-2000. METHODS Computerized pharmacy, outpatient visit, and membership files were used to conduct a population-based analysis of stimulant use among over 500,000 enrollees aged 2-18 years. Annual prevalence rates of stimulant use were estimated by calendar year, age, gender, and geographic area. RESULTS The annual percentage of continuously enrolled 2- through 18-year-olds receiving at least one prescription for a stimulant rose from 1.86% (95% confidence interval (CI) 1.82-1.90) in 1996 to 1.93% (95% CI, 1.90-1.96) in 2000. An increase was observed only among girls 8 years of age or older and among boys 12 years or older. Use of methylphenidate decreased, whereas use of extended-release amphetamine products increased. Stimulant use was lower and use of other psychotropic drugs was higher among children with visits for attention-deficit/hyperactivity disorder (ADHD) and a coexisting psychiatric disorder than among those seen for ADHD alone. Of the 11,698 children receiving at least one stimulant in 2000, 24% of these children received a single prescription. Approximately 55% of stimulant prescriptions were written by physicians in pediatrics and 45% by physicians in psychiatry. CONCLUSIONS The prevalence of treatment with stimulants was lower than what generally has been reported in other parts of the United States; it increased by approximately 4% between 1996 and 2000, and was frequently short term or intermittent.

Abstract
This present study investigated the prevalence and the factors associated with the use, misuse, and diversion of prescribed stimulant medication for attention-deficit hyperactivity disorder (ADHD) in a sample of middle and high school students. As part of a school-based, self-administered web survey in May 2002, students from a Midwestern public school district in the United States in grades six through eleven (n = 1536) reported on three aspects of prescription stimulants; they reported on their use, misuse, and diversion (e.g. trading, selling, offering) of stimulant medication for ADHD. The total student sample was 57% White, 40% African American, and 3% other racial and ethnic groups. Gender and school level were approximately equally distributed in the student sample, and 81% of students had plans to attend college. The illicit use of stimulant medication was reported by 4.5% of the overall sample. Of the students who reported prescription stimulant use, 23.3% reported being approached to sell, give, or trade their prescription drugs. After adjusting for socio-demographic factors, the odds for illicit use of stimulant medication was lower among African American students and higher among those students with no plans for attending college. When compared with students who did not use stimulants or who did not misuse stimulant medications also reported significantly higher rates of alcohol and other drug use. High schools students had the highest rates of alcohol and other drug use. High schools students had the highest odds for being approached to divert their stimulant medications. Our findings suggest that community-based approaches are needed to reduce the illicit use and diversion of stimulant medications within middle and high school student populations.

Abstract
INTRODUCTION The use of methylphenidate for the treatment of attention deficit-hyperactivity disorder (ADHD) has increased dramatically in the past decade in some countries in Europe and North America. In response to a public debate in Israel, several Knesset members introduced a legislative initiative that aims to limit the prescription of methylphenidate by physicians. The objective of this study was to examine the rate methylphenidate prescriptions dispensed for the treatment of ADHD in children in northern and central Israel in 1999 and 2001. PATIENTS AND STUDY DESIGN The population included all children aged 0-18 years living in central or northern Israel and insured by the largest national health management organisation who were prescribed methylphenidate at least once in 1999 or 2001. This was a population-based prevalence study comparing the two timepoints using data from the health management organisation and descriptive statistics. RESULTS The overall 1-year prevalence of methylphenidate prescriptions dispensed to children was 1.01% in 1999 and 1.22% in 2001 (relative risk [RR] 1.21, 95% CI 1.15-1.26), an increase of 21%. Seventy-seven percent of those prescribed methylphenidate were boys. The prescription rate ranged from 0.2% (RR 1.24, 95% CI 0.76-2.05) in Arabic cities to 5.99% (RR 1.19, 95% CI 1.09-1.30) in kibbutzim; this wide variation by type of residence apparently involved cultural, racial and economic factors. CONCLUSION Israel shows no unusual or unexpected patterns in methylphenidate prescriptions dispensed to children and a lesser increase over time than other developed countries. This suggests that limiting physician freedom to prescribe methylphenidate to children may not be justified.

Abstract
OBJECTIVE It is widely believed that only a minority of vulnerable children and adolescents receive any mental health services. Although health care disparities associated with sociodemographic characteristics are well known, almost no information exists about another potentially important source of disparity for children: How does state of residence affect mental health service use? METHODS Observational analysis was conducted using the 1997 and 1999 waves of the National Survey of America's Families (N = 45 247 children aged 6-17), a population survey fielded in 13 states and a smaller geographically dispersed sample. We studied 4 dependent variables: 1) use of any mental health services and number of visits among users; 2) need for mental health care, based on 6 items from the Child Behavior Checklist; 3) unmet need (no services among children with identified need); and 4) need among users of mental health services. RESULTS Use of any mental health care differs >2-fold across states, ranging from 5% in California and Texas to >10% in Colorado and Massachusetts. The variation across states in service use and unmet need exceeds the differences across racial/ethnic groups or family income. For example, the odds ratio of unmet need in California versus Massachusetts is 3.04, compared with 2.33 between Hispanic and white children. Differences in population characteristics across states do not explain much of the observed geographic variation in mental health related outcomes for children. Perhaps the most disconcerting finding is that the differences in use are not paralleled by differences in need. Overall, there is no apparent relationship between levels of need and use of services across states. As a general rule, states with high rates of services do not have low levels of need or vice versa, although that situation exists. Alabama and Texas, for example, have higher rates of need and lower rates of use than the nation as a whole, whereas Washington state displays the opposite pattern. Even with the similar levels of need and service use, states differ in the effectiveness of their delivery system. Alabama and Mississippi have high rates of need and low levels of use, but rates of unmet need are not significantly higher in those 2 states than in the nation, whereas California, Florida, and Texas have the highest rates of unmet need. In California and Texas, children from high-income families are more likely to receive some mental health services than children from low-income families. In Alabama and Mississippi, as well as in the states with the lowest rates of unmet need (Colorado, Massachusetts, and Minnesota), the opposite is true: children from low-income families are much more likely to receive any mental health service than children from high-income families. CONCLUSIONS Large differences from the national average across states in service use and unmet need are the rule, rather than the exception. National averages obscure large differences that can exceed the effects of race/ethnicity or income. The differences in the rates of use or unmet need are not driven by differences in the racial/ethnic or socioeconomic makeup across states but more likely are the result of differences in state policies and health care market characteristics. These state policies and health care market characteristics can interact with sociodemographic characteristics and affect how effectively resources are used. For states such as California and Texas that have the lowest rates of mental health service use, it may be less important to raise the rates of service use than to deliver them to the children with the highest need, predominantly black and Hispanic children and children in low-income families.

Abstract
Management of a child or adolescent with attention-deficit/hyperactivity disorder (ADHD) is reviewed, including psychological and pharmacologic approaches. Psychological treatment includes psychotherapy, cognitive-behavior therapy, support groups, parent training, educator/teacher training, biofeedback, meditation, and social skills training. Medications are reviewed that research has revealed can improve the core symptomatology of a child or adolescent with ADHD. These medications include stimulants, antidepressants, alpha-2 agonists, and a norepinephrine reuptake inhibitor. Management of ADHD should include a multi-modal approach, involving appropriate educational interventions, appropriate psychological management of the patient (child or adolescent), and judicious use of medications. Parents, school officials, and clinicians must work together to help all children and adolescents with ADHD achieve their maximum potential.

Abstract
This study evaluates a measurement model for Attention Deficit/Hyperactivity Disorder (ADHD). The DSM-IV divides 18 symptoms into two groups, inattentive and hyperactive/impulsive. Elementary school teachers rated 21,161 children in 4 locations: Spain, Germany, urban US, and suburban US. Confirmatory factor analysis suggested that the 2-factor model (inattention, hyperactivity/impulsivity) shows the best fit. A third factor, impulsivity, was too slight to stand-alone. Children with academic performance problems were distinguished by inattention, but children with behavior problems typically had elevations in inattention, hyperactivity, and impulsivity. Between-site differences were statistically significant, but so small that we conclude that same measurement model fits all 4 samples in 2 continents.

Abstract
This study was undertaken to explore psychosocial factors associated with referral for attention deficit hyperactivity disorder (ADHD) evaluation or ADHD diagnosis among elementary school children in Rhode Island, as well as to examine the extent of drug therapy among this population. A survey was distributed to parents/guardians of 2,800 3rd- to 5th-grade public school students in 4 Rhode Island school districts. The average age of the children was 9.0 +/- 1.0 years with 52% girls. Approximately 12% of the students had been referred for ADHD evaluation (RFE). Of these, 52% (6% of all children in the survey) were receiving psychoactive prescription medications daily. While the male:female ratio in the non-RFE group was almost 1:1, there were more boys than girls in the RFE group (male/female ratio of 3:1, p < 0.0001) and in the medicated group (male/female ratio 4:1, p < 0.0001). RFE children and medicated children were older than classroom peers (p < 0.0001), and had a greater degree of school misconduct (p < 0.0001). RFE children and medicated children were significantly less likely to have parents who completed college (p < 0.05), were significantly more likely to have stepparents (p < 0.05), and to be only children (p < 0.05) when compared with their peers. Amphetamine was the most commonly prescribed drug (used by 54% of the medicated children) followed by methylphenidate (43%). Nearly 18% of the medicated children were receiving 1 to 3 additional psychoactive prescription medications on a daily basis. In conclusion, RFE children and children medicated for ADHD were more likely to have a stepparent, have no siblings, and have parents that had not completed college. Amphetamine rather than methylphenidate accounted for the majority of medications used in this study, and simultaneous use of multiple psychoactive medications was reported in 18% of the medicated children.

Abstract
BACKGROUND Population-based studies of pharmaceutical use in children provide information on disease prevalence, physician practice and adherence to treatment. We undertook an evaluation of regional differences in prescription drug use by Manitoba children. METHODS Using Manitoba's population-based prescription data for 1998/99, the prevalence of children receiving prescriptions for antibiotics, analgesics, iron supplements, and four classes of psychotropic drugs was reported for Regional Health Authorities and Winnipeg Community Areas, ranked by a measure of population healthiness, the premature mortality rate (PMR). Prevalence rates were also reported by census-based neighbourhood income areas. RESULTS 60% of children received at least one prescription in 1998/99. Antibiotics, antiasthmatics, analgesics, antidepressants, and psychostimulants were the most commonly dispensed drugs. Prescription use of antibiotics, iron supplements, analgesics, antidepressants, antipsychotics and anxiolytics was highest in low income, urban neighbourhoods. Few associations between a region's PMR and prescription utilization were observed, but children living in regions with the least healthy populations were more likely to use antibiotics, non-steroidal anti-inflammatory drugs and anxiolytics. Psychostimulant use was unrelated to neighbourhood income, but highest rates were documented in some of the healthiest Winnipeg neighbourhoods. CONCLUSION We documented regional variation in prescription use which may be related to differences in health, physician practice or child use.

Abstract
This study describes 4 help-seeking steps among children at high risk for attention deficit hyperactivity disorder (ADHD), and identifies barriers to ADHD symptom detection and treatment. Using a district-wide stratified random sample of 1615 elementary school students screened for ADHD risk, predictors of 4 help-seeking steps among a high-risk group (n = 389) and parent-identified barriers to care among children with unmet need for ADHD care (n = 91) were assessed. Study findings indicate that although 88% of children were recognized as having a problem, only 39% had been evaluated, 32% received an ADHD diagnosis, and 23% received current treatment. Older children and those with more severe behavior problems were more likely to be perceived by their parents as having a problem. Additionally, gender and ethnic disparities in the subsequent help-seeking process emerged. Boys had over 5 times the odds than girls of receiving an evaluation, an ADHD diagnosis, and treatment. Compared to African American youth, Caucasian children had twice the odds of taking these help-seeking steps. For those children with unmet need for ADHD care, poverty predicted lower treatment rates and was associated with the most pervasive barriers. The gap between parental problem recognition and seeking services suggests that thresholds for parental recognition of a child behavior problem and for seeking ADHD services may be different. Future research examining the help-seeking process for ADHD should include a qualitative component to explore the potential mechanisms for gender and ethnic differences.

Abstract
CONTEXT While an association between pediatric behavioral disorders and injuries is generally acknowledged, no studies have measured the risk for injury in the context of a large, population-based study that is free of cohort biases. OBJECTIVES To examine the association between childhood behavior disorders ([CBDs] as indicated by prescription for methylphenidate [MPH]) and a variety of injury outcomes, and to evaluate the risk for injury among these children after controlling for known demographic correlates. DESIGN Population-based database analysis of all children in British Columbia (BC) under the age of 19 as of December 31, 1996; comparison of those who had been prescribed MPH and therefore placed in the CBD group (n = 16, 806) and those who were not (n = 1,010,067). Demographic information collected was as follows: age, sex, measures of socioeconomic status, and region of residence. OUTCOME MEASURES Common types of childhood injury in BC: International Classification of Diseases, Ninth Revision N-codes (fractures, open wounds, poisoning/toxic effect, concussion, intracranial, burns) and E-codes (falls, postoperative complications, motor vehicle accidents, struck by object, adverse effects of drugs, suffocation, drowning). DATA SOURCE BC Linked Health Data Set and the BC Triplicate Prescription Program. RESULTS After controlling for known demographic correlates, odds for injury was greater among those treated with MPH and presumed to have a behavioral disorder, when injury was characterized either by type (1.67; 99% confidence interval: 1.54-1.81) or cause (1.52; 99% confidence interval: 1.40-1.66) of injury. This increased risk extended to unexpected categories of injury such as postoperative complications and adverse effects of drugs. CONCLUSIONS Children with CBDs have >1.5 times the odds of sustaining injuries of a variety of types from a variety of causes, even after controlling for known demographic correlates, than those without behavioral disorders. The risks for these children extend beyond those that might be directly associated with impulsivity and overactivity. Injury prevention strategies aimed at this group of children and youth would be beneficial. Policy-makers should account for increased risk of a wide variety of injuries in this group of children and youth.

Abstract
BACKGROUND Prescribing practices amongst child and adolescent psychiatrists in other countries appear to have changed in the past 10 years. This study sought to examine changes over the same time period in the UK. METHOD A questionnaire survey of prescribing practices of child and adolescent psychiatrists in Oxford Region and Wales was compared with results of a similar survey of Oxford Region 7 years previously. RESULTS The notable changes over time were an increase in prescribing to treat Attention Deficit Hyperactivity Disorder and an increase in prescribing of selective serotonin reuptake inhibitors for the treatment of depression. The findings between Oxford and Wales in the year 2000 were similar, suggesting that these findings may be generalised throughout Britain. CONCLUSIONS Prescribing practices in the UK may have changed in the past decade with more use of stimulants and SSRIs. This is similar to the changes noted in the USA.

Abstract
BACKGROUND Psychotropic medications have become an integral component in the treatment of children with mental illnesses. METHODS Selective reviews of the empirical evidence for the efficacy of psychotropic medications and studies of their use patterns were reviewed. RESULTS Very strong efficacy for at least the short-term benefits and safety of stimulant medications was found and some good efficacy and safety evidence for the treatment of anxiety and depressive disorders with seratonin reuptake inhibitors (SSRI) was also found. Efficacy for tricyclic antidepressants to treat attention deficit hyperactivity disorder was found but the presence of significant side effects makes them less the drugs of choice. Other medications are presented but with less rigorous evidence. Studies of use found that stimulant medications are extensively prescribed in the US by both psychiatrists and primary care physicians. SSRI are also prescribed extensively but not to the extent of stimulants and are more frequently prescribed by psychiatrists. CONCLUSIONS There is now good evidence for the efficacy of some psychotropic agents and their use is an integral component in the management of childhood mental illnesses.

Abstract
OBJECTIVE The purpose of this study was to evaluate geographic variation in the prevalence of prescription stimulant use and predictors of use among a nationally representative, commercially insured population 5 to 14 years old. METHODS Prescription claims activity from January 1, 1999 through December 31, 1999 for a continuously eligible population 5 to 14 years old was evaluated. Age-gender adjusted prevalence rates were estimated for each state. Multivariate logistic regression using hierarchical linear modeling was used to evaluate the impact of age, gender, number of child dependents, and region of the country on stimulant prevalence. The contextual effects of urban or rural residence, median income, percent white, and physician rate per 100 000 residents were also controlled for. RESULTS The 1-year prevalence of stimulant treatment for the entire study sample was 4.2%. Multivariate logistic regression indicated that stimulant prescription use was positively associated with age, male gender, fewer child dependents, living in higher income communities, and living in communities with greater percent white. Compared with children living in the Western region of the country, children living in the Midwest and South were 1.55 (99% confidence interval: 1.28-1.87) and 1.71 (99% confidence interval: 1.42-2.06) times more likely to consume at least 1 stimulant medication, respectively. Differences in stimulant prevalence across urban and rural residence were also noted. CONCLUSIONS Geographic variation in the prevalence of stimulant use exists nationally, despite controlling for important predictors of use including age and gender. Possible reasons for the variation are discussed as are calls for additional research.

Abstract
Children evaluated for attention deficit hyperactivity disorder (ADHD) may have other disorders resembling ADHD leading to inappropriate stimulant medication use. This study was completed to identify relationships between referral complaints of ADHD, behavior problems or learning problems and age, gender, final diagnosis, and medication use. One hundred eighty-nine children ages 2 to 15 years referred for evaluation of ADHD, behavior or learning problems were evaluated by an interdisciplinary team. Diagnoses of ADHD, specific learning disability (SLD), mental retardation (MR), developmental language disorders (LANG), and other behavior disorders (DIS) were established. Medication use pre- and post-evaluation was reviewed. Forty-three percent of all subjects had a final diagnosis of ADHD. Forty percent referred specifically for presumed ADHD did not have it. More children older than 5 years were diagnosed as having ADHD than those 5 years old or younger (p < 0.0001). More subjects 5 years old or younger were diagnosed as having LANG than those older than 5 years (p < 0.0001). Fewer subjects with a chief complaint of ADHD were diagnosed with MR than those with behavior or learning problems (p = 0.001). In subjects 5 years old or younger, 35% were diagnosed with MR and 49% with other DIS. In children older than 5 years, 41% were diagnosed with SLD. Ten percent of subjects without ADHD were using stimulants. Only 48% of subjects with confirmed ADHD took stimulants. Children presenting with behavior problems or those 5 years old or younger are at higher risk for MR, LANG, and DIS and less likely to have ADHD. Children presenting with learning problems or those older than 5 years are more likely to have SLD or ADHD. Multiple diagnoses were common for all ages and presentations. Ten percent of children without confirmed ADHD used stimulants before evaluation.

Abstract
OBJECTIVE A retrospective analysis of archival data on psychostimulant prescriptions from South Australia for the period 1990 to 2000 for 5,189 youths from birth to age 18 years was conducted. METHOD A person-based data set was used to assess (1) rate of new prescriptions by age group, (2) demographic characteristics (age of psychostimulant start, male-to-female ratio), (3) duration of psychostimulant use, and (4) geographic variation in psychostimulant prescription. RESULTS Four major findings were observed: (1) the rate of new prescriptions increased dramatically until 1995 but is now declining; (2) demographic characteristics and changes over time mirror those observed in the United States; (3) median duration of psychostimulant use (for a subset of 1,688 children) was approximately 2.5 years; and (4) there was a significant correlation between geographic location and prescription rate. CONCLUSIONS The patterns of psychostimulant use in Australia closely parallel U.S. patterns. Physicians'prescribing practices may be extremely volatile. Duration of medication treatment should receive increased attention. There is pronounced geographic variability in prescription rates which may be related to socioeconomic status.

Abstract
OBJECTIVE To provide a description of the ambulatory use of psychotropic medications by children and adolescents in a large, geographically diverse employer-insured population. DESIGN This retrospective observational study used administrative claims data for 1995-1999 for members under age 20 in 6 Independent Practice Association health plans affiliated with UnitedHealth Group. We calculated the prevalences of use for 4 major therapeutic drug classes: central nervous system stimulants (CNSSs), selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), and other antidepressants (OADs). Changes over time by age, gender, geographic region, and prescriber specialty were analyzed across drug classes. RESULTS The prevalence of CNSS, SSRI, and OAD use steadily increased over the 5-year period, whereas TCA use decreased. The prevalence of use of the most commonly used classes, the CNSS and SSRI classes, increased from 23.8 to 30.0 per 1000 and 7.9 to 12.8, respectively. There was variability across and within geographic regions. Pediatricians were the most frequent first prescribers of CNSS, and psychiatrists were most likely to prescribe SSRIs. CONCLUSION Acceleration of use of psychotropic medications is slower in an employer-insured national population. Since primary care physicians are frequent prescribers of psychotropics, their training and expertise are crucial.

Abstract
Psychotropic medications are increasingly used for very young children. Patterns of use in a well-described group of children 3 years and younger with a diagnostic label of attention-deficit hyperactivity disorder (ADHD) reveal both reasons to use such medications and concerns about how these medications are used. Of 223 children with ADHD, more than half (n = 127) received psychotropic medications in an idiosyncratic manner, both in the specific medication and in use over time. Almost half of the children who were medicated did not have opportunities for monitoring as often as every 3 months, despite the fact that more than half received psychotropic medications for 6 months or longer. Children with comorbid mental health conditions and chronic health conditions were at greater risk for receiving psychotropic medications. These patterns of use demonstrate a compelling need for guidance in psychopharmacological treatment of very young children.
