The aim of this paper was to discuss the arguments for and against the use of atypical antipsychotics in children and adolescents with aggression, and provide recommendations for future research. A MEDLINE search (1985-2004) was performed to identify key literature. Search terms included, but were not limited to, clozapine, olanzapine, quetiapine, risperidone, ziprasidone, children, and adolescents. The search was limited to English-language literature and randomized controlled trials. The use of atypical antipsychotics in children and adolescents has increased significantly over the past few years. Atypical antipsychotics are associated with a more favorable side-effect profile, and growing evidence supports their efficacy for aggression in this population. However, the long-term effects of these agents are unknown. No head-to-head evidence exists to suggest whether pharmacological or nonpharmacological treatments are superior for managing aggression associated with childhood and adolescent psychiatric and behavioral conditions. Future research of atypical antipsychotics in children and adolescents needs to evaluate not only the efficacy but also the effectiveness. Examination of treatment mediators and moderators may help to optimize treatment regimens and improve patient outcomes. Finally, effective interventions require the development and implementation of evidence-based treatment strategies using a multidisciplinary approach.

In the rising quest for evidence-based interventions, recent research often does not give adequate attention to "nonspecific therapeutic factors," including the effects of attention, positive regard, and therapeutic alliance, as well as the effects of treatment dose, intensity and actual processes mediating therapeutic change. To determine the extent to which recent clinical trial designs fully this problem, the authors conducted a systematic review of Psych-Lit/Medline of all controlled child psychotherapy treatment studies from 1995 to 2004. A total of 52 studies were identified that met review criteria: two or more therapy conditions and random assignment of participants to intervention groups. Of the 52 studies, one group (n = 29) compared a presumably active treatment with 1 or more similarly intensive treatments (often an attention control group) presumably not containing the active therapeutic ingredients. Of these, 14 studies found evidence of consistent differences between the two groups, whereas 15 did not. An additional group of studies (n = 27) compared therapy groups with different levels of intensity and "dose" of the putatively active treatment; 13 of these found evidence of the effects of different levels of treatment dose/intensity on outcomes and 14 did not. Four studies met criteria for inclusion in both groups. Across both groups of studies, when positive effects were found, few studies systematically explored whether the presumed active therapeutic ingredients actually accounted for the degree of change, nor did they often address plausible alternative explanations, such as nonspecific therapeutic factors of positive expectancies, therapeutic alliance, or attention. Findings suggest that many child psychotherapy treatment studies have not inadequately controlled for nonspecific factors such as attention and treatment intensity and have failed to assess specific mediators of change. Specific recommendations for future studies are offered, specifically: 1. Initial specification in study design how investigators will test if the intervention is efficacious over and above the effects of positive expectancies, positive regard, or attention; 2. Planned (rather than post hoc) analyses to explore whether and how a given treatment's specific ingredients or the overall intensity of its "dose" are related to treatment outcomes; 3. More studies conducting head-to-head tests of different types but equally credible forms of treatment, with planned analyses testing different mechanisms of change 4. When positive effects of a treatment vs. a control are found, systematic elimination of specific, competing hypotheses of reasons for treatment efficacy (e.g., attention, therapeutic alliance, face validity of treatment and client's treatment expectations, changes in self-efficacy), and 5. When negative effects are reported, appropriate analyses to address alternative explanations (lack of power, floor or ceiling effects, mediator analyses to address possible fidelity or adherence problems, therapist effects, absence of main effects but possible subgroup/moderator effects, etc.).

Major national, state, and local systems reform efforts are under way to close the gap between science and service through implementation of a range of evidence-based practices (EBPs). A set of rhetorical distinctions and ensuing debates about the relevance of science versus service and efficacy versus effectiveness threatens to widen rather than close the gap. However, methodological and conceptual approaches, drawing upon strong theory-driven models, offer considerable promise for an integrated science on implementation effectiveness. This paper outlines some of the major scientific and policy challenges in strengthening the link between science and service in school psychology within the context of the papers in this series.

This paper describes the process of modifying and transporting an evidence-based treatment, Interpersonal Psychotherapy for Depressed Adolescents (IPT-A), from a university setting to school-based health clinics. It addresses conceptual issues involved in the shift from efficacy to effectiveness research as well as operational issues specific to the transport of IPT-A into school-based health clinics. Consideration is given to the rationale for an IPT-A effectiveness study, methodological concerns, and the timing of the move from the "lab" to the community. The authors identify challenges and barriers to initiating effectiveness and transportability research and provide suggestions for overcoming these barriers. Recommendations for conducting research in school-based practice settings are provided.

OBJECTIVE: To describe the psychometric properties and test the reliability of a new instrument designed to measure mental health services use within pediatric clinical samples, the Services for Children and Adolescents-Parent Interview (SCAPI), which was developed by the National Institute of Mental Health Multimodal Treatment Study of Children With Attention Deficit Hyperactivity Disorder (MTA). METHOD: Similarities and differences with other measures of services use are described. Ten types of services are measured by the SCAPI. Formal test-retest reliability testing was carried out in 104 subjects with a mean time between tests of 18 days. RESULTS: Test-retest kappa values ranged from 0.49 to 1.00, with an overall kappa value for all services of 0.97. Seven of the 10 service types had kappa values of 0.75 or higher, indicating excellent reliability. In addition, matched responses on specific questions about reasons for seeking services, starting and ending dates, number and length of visits, and type of provider seen were more than 75% for most service categories, consistently so for reporting of medications and school services. CONCLUSIONS: The SCAPI is a reliable instrument for assessing mental health and related services use and may be an especially valuable adjunct in studies involving clinical samples, especially clinical trials.

OBJECTIVE: To date, no instrument has been developed that captures children's services use across primary care, specialty mental health, and other settings, including setting, treatment type, provider discipline, and length and intensity of specific interventions over varying follow-up periods. The authors developed a highly structured services assessment measure [Services for Children and Adolescents-Parent Interview (SCAPI)] for use in the National Institute of Mental Health Multimodal Treatment Study of Children With Attention Deficit Hyperactivity Disorder (MTA). METHOD: After successfully piloting and refining the SCAPI during initial phases of the MTA, the authors used this measure at 24 months post-randomization to ascertain the previous 6 months of services use for all participating (516 of 579) MTA children and families and 285 age- and gender-matched classroom control children. RESULTS: Findings revealed meaningful, face-valid differences between MTA and control children in levels and types of services used during the previous 6-month period. Services use data reported by parents was substantially in accord with data independently gathered by the research data center. Site variations were found in the level and use of several specific services, such as individual child psychotherapy (sites ranged from 0% to 6.8% among classroom controls compared with 9.7% to 46.1% among MTA participants) and special education services (0% to 14.6% among classroom controls, 27.5% to 34.8% among MTA participants), consistent with differences reported in other studies. CONCLUSIONS: These data support the descriptive validity of SCAPI-ascertained services use data and indicate that the SCAPI can provide investigators and policymakers a valid means of assessing services type, intensity, onset and offset, provider type, and content.

OBJECTIVE: : Clinical research depends on the participation of representative samples. At the 2001 Annual Meeting of the American Academy of Child and Adolescent Psychiatry, the Workgroup on Research conducted a research forum with the purpose of improving recruitment and retention of children and adolescents in research protocols. METHOD: : An interdisciplinary group of participants focused on (1) consumers and families, (2) communities, (3) professionals and health care delivery systems, (4) regulatory bodies, and (5) alternative research designs. Obstacles and challenges were identified and solutions were discussed. RESULTS: : Key recommendations include the following: Investigators must become involved with community stakeholders and more explicitly communicate with families about research procedures, risks, and benefits; budgets should include explicit items for case management and referrals to families who do not meet entry criteria; the culture of clinical settings must incorporate research conducted by clinicians; regulatory bodies must streamline and coordinate protocols and procedures; designs emphasizing flexible treatment strategies and adaptive treatments should be encouraged; and health care systems should consider changing incentives for research participation, including the radical notion that reimbursement be made in terms of improvement rather than service units. CONCLUSIONS: : An integrated approach is recommended, requiring direct involvement of investigators in communities where research is to be conducted
