Treatment services for children with ADHD: a national perspective.

OBJECTIVE: To summarize knowledge on treatment services for children and adolescents with attention-deficit hyperactivity disorder (ADHD), trends in services from 1989 to 1996, types of services provided, service mix, and barriers to care. METHOD: A review of the literature and analyses from 2 national surveys of physician practices are presented. RESULTS: Major shifts have occurred in stimulant prescriptions since 1989, with prescriptions now comprising three fourths of all visits to physicians by children with ADHD. Between 1989 and 1996, related services, such as health counseling, for children with ADHD increased 10-fold, and diagnostic services increased 3-fold. Provision of psychotherapy, however, decreased from 40% of pediatric visits to only 25% in the same time frame. Follow-up care also decreased from more than 90% of visits to only 75%. Family practitioners were more likely than either pediatricians or psychiatrists to prescribe stimulants and less likely to use diagnostic services, provide mental health counseling, or recommend follow-up care. About 50% of children with identified ADHD seen in real-world practice settings receive care that corresponds to guidelines of the American Academy of Child and Adolescent Psychiatry. Physicians reported significant barriers to service provision for these children, including lack of pediatric specialists, insurance obstacles, and lengthy waiting lists. CONCLUSIONS: The trends in treatment services and physician variations in service delivery point to major gaps between the research base and clinical practice. Clinical variations may reflect training differences, unevenness in the availability of specialists and location of services, and changes in health care incentives.

Use of the Pediatric Symptom Checklist to screen for psychosocial problems in pediatric primary care: a national feasibility study.

BACKGROUND: Routine use of a brief psychosocial screening instrument has been proposed as a means of improving recognition, management, and referral of children's psychosocial morbidity in primary care. OBJECTIVE: To assess the feasibility of routine psychosocial screening using the Pediatric Symptom Checklist (PSC) in pediatrics by using a brief version of the checklist in a large sample representative of the full range of pediatric practice settings in the United States and Canada. We evaluated large-scale screening and the performance of the PSC in detecting psychosocial problems by (1) determining whether the prevalence of psychosocial dysfunction identified by the PSC was consistent with findings in previous, smaller samples; (2) assessing whether the prevalence of positive PSC screening scores varied by population subgroups; and (3) determining whether the PSC was completed by a significant proportion of parents from all subgroups and settings. PATIENTS AND METHODS: Twenty-one thousand sixty-five children between the ages of 4 and 15 years were seen in 2 large primary care networks: the Ambulatory Sentinel Practice Network and the Pediatric Research in Office Settings network, involving 395 pediatric and family practice clinicians in 44 states, Puerto Rico, and 4 Canadian provinces. Parents were asked to complete a brief questionnaire that included demographic information, history of mental health services, the 35-item PSC, and the number of pediatric visits within the past 6 months. RESULTS: The overall prevalence rates of psychosocial dysfunction as measured by the PSC in school-aged and preschool-aged pediatric outpatients (13% and 10%, respectively) were nearly identical to the rates that had been reported in several smaller samples (12%-14% among school-aged children and 7%-14% among preschoolers). Consistent with previous findings, children from low-income families were twice as likely to be scored as dysfunctional on the PSC than were children from higher-income families. Similarly, children from single-parent as opposed to those from 2-parent families and children with a past history of mental health services showed an elevated risk of psychosocial impairment. The current study was the first to demonstrate a 50% increase in risk of impairment for male children. The overall rate of completed forms was 97%, well within an acceptable range, and at least 94% of the parents in each sociodemographic subgroup completed the PSC form. CONCLUSIONS: Use of the PSC offers an approach to the recognition of psychosocial dysfunction that is sufficiently consistent across groups and locales to become part of comprehensive pediatric care in virtually all outpatient settings. In addition to its clinical utility, the consistency and widespread acceptability of the PSC make it well suited for the next generation of pediatric mental health services research, which can address whether earlier recognition of and intervention for psychosocial problems in pediatrics will lead to cost-effective outcomes.

Somatization in pediatric primary care: association with psychopathology, functional impairment, and use of services.

OBJECTIVE: To determine whether classification as pediatric "somatizers" identifies a group of children and adolescents at high risk for psychopathology, functional impairment, and frequent use of health services in a large, multisite study of pediatric primary care. METHOD: Parental reports of frequent aches and pains and visits to the doctor for medically unexplained symptoms in children aged 4 to 15 years were used to construct a classification of somatization in pediatric primary care. Affected and unaffected children and adolescents were compared on measures of demographics, family functioning, psychopathology, functional status, and service use. RESULTS: Classification as a somatizer was more common in adolescents, females, minority subjects, urban practices, nonintact families, and families with lower levels of parental education and was associated with heightened risk of clinician- and parent-identified psychopathology, family dysfunction, poor school performance and attendance, perceived health impairment, and more frequent use of health and mental health services. CONCLUSIONS: Children classified as pediatric somatizers are at heightened risk for psychiatric disorder, family dysfunction, functional impairment, and frequent use of health services. Additional research is warranted, and clinicians should recognize the need for careful assessment and potential behavioral health referral in this population.

The Physician Belief Scale and psychosocial problems in children: a report from the Pediatric Research in Office Settings and the Ambulatory Sentinel Practice Network.

Clinicians' management of children with psychosocial problems may vary with their attitudes and beliefs. However, we lack sound instruments to assess these factors. This study examined the psychometric properties of the Physician Belief Scale (PBS). A modified version of the PBS was sent to clinicians who participated in two primary care research networks. Using factor analysis, we reduced the PBS to 14 items and 2 subscales. Cronbach's alpha values were high. Female clinicians, those using DSM-IV, and those having completed training earlier rated themselves as more psychosocially oriented. Identification and treatment of psychosocial problems were significantly related to scores on the Belief and Feeling subscale. The PBS provided only a modest amount of information regarding primary care practices. It is not clear if these limitations are attributable to the instrument or the many other barriers to effective psychosocial care.

Patient race and ethnicity in primary care management of child behavior problems: a report from PROS and ASPN. Pediatric Research in Office Settings. Ambulatory Sentinel Practice Network.

BACKGROUND: Minority persons have less access to many specialty treatments and services, possibly because of clinician biases. It is not clear whether any such biases exist in primary care settings, especially for children with psychosocial problems. OBJECTIVES: The objective was to compare primary care recognition and treatment of pediatric psychosocial problems among African American, Hispanic American and European American patients. DESIGN: A survey was made of parents and respective clinicians in primary care offices in two large practice-based research networks (PROS and ASPN) from 44 states, Canada, and Puerto Rico. Mixed regression analyses were employed to control for patient, clinician, and practice effects. SUBJECTS: The subjects were 14,910 children aged 4 to 15 years seen consecutively for non-emergent care by 286 primary care clinicians in office-based practice. MEASURES: Measures were parents' report for sociodemographics and behavioral symptoms using the Pediatric Symptom Checklist, and clinicians' report of psychosocial problems, type, management, and severity. RESULTS: Of the sample, 8.0% were African American youth, 9.5% were Hispanic American youth, and 82.5% were European American youth. After controlling for other factors, race and ethnicity were not associated with any differences in psychotropic drug prescribing, counseling, referral, or recognition of psychosocial problems. Clinicians reported spending slightly more time with minority patients. CONCLUSION: Race and ethnic status were not related to receipt of mental health services for children in primary care offices, suggesting that clinician biases may not be the primary cause of the racial differences in services noted earlier research. Improving services for minority youth may require increasing access to office-based primary care.
