IMPORTANCEEmerging evidence suggests that integrated care models are associated with improved mental health care access and outcomes for youths (children Յ12 years and adolescents 12-21 years) served in pediatric primary care settings. However, the key components of these complex models remain unexamined.OBJECTIVE To identify and describe the key components of effective pediatric integrated mental health care models. EVIDENCE REVIEWThe PubMed, Embase, PsycINFO, and Cochrane Controlled Register of Trials electronic databases were searched for relevant peer-reviewed articles published between January 1, 1985, and April 30, 2019. Articles were restricted to those published in the English language. Eligible articles reported original data on youths 17 years or younger, implemented an integrated mental health care model in a pediatric primary care setting, and assessed the model's association with primary outcomes (eg, mental health symptom severity) and secondary outcomes (eg, functional impairment and patient satisfaction). Articles that specified some degree of systematic coordination or collaboration between primary care and mental health professionals were included in the final review. Two independent reviewers extracted data on study design, model type, model components, level of integration, and outcomes. Study quality was assessed using the Jadad scale. Data were analyzed between January 1, 2018, and May 31, 2019.FINDINGS Eleven randomized clinical trials involving 2190 participants were included. Three studies focused on youths with depression, 3 on youths with attention-deficit/hyperactivity disorder, and 5 on youths with behavioral disorders. Most studies (9 of 11) implemented either the collaborative care model (n = 3), a slightly modified version of the collaborative care model (n = 2), or colocated care (n = 4). The most commonly reported components of effective pediatric integrated mental health care models were population-based care, measurement-based care, and delivery of evidence-based mental health services; all 3 components were present in studies reporting clinical improvement of mental health symptoms. Other model components, such as treatment-to-target or team-based care, were common in studies reporting specific outcomes, such as functional impairment. CONCLUSIONS AND RELEVANCEThis review is the first to date to systematically search and qualitatively synthesize information on the key components of effective pediatric integrated mental health care models. This knowledge may be especially useful for pediatric primary care administrators in the selection of an integrated care model for their setting.

Objective: Nonincarcerated (community-supervised) youths who are first-time offenders have high rates of mental and substance use disorders. However, little is known about their use of psychiatric services (mental health and substance use) or factors associated with service use. This study examined the prevalence, determinants, and barriers to service use among community-supervised youths.Methods: Data were from a longitudinal study of mental health and substance use outcomes among adolescents ages 12-18 from a northeastern family court in which caregivers and youths completed assessments (N=423 dyads). The Behavior Assessment System for Children, Second Edition, assessed youths' psychiatric symptoms. The Child and Adolescent Services Assessment assessed service use and barriers. Family functioning and caregiver-adolescent communication were assessed with the McMaster Family Assessment Device and the Parent-Adolescent General Communication Scale, respectively. Multivariable regression analyses examined the cross-sectional relationship between youths' service use and determinants of use at baseline.Results: Of the 423 youths, 49% experienced psychiatric symptoms and 36% used psychiatric services in the past 4 months. The highest adjusted odds of service use were associated with youths' psychiatric symptoms and caregivers' history of a psychiatric diagnosis. The lowest odds were associated with caregivers' identifying as being from racial and ethnic minority groups. Caregiver-reported barriers to service use differed according to prior service use and by caregiver race-ethnicity.Conclusions: Results suggest a need for interventions to increase access to and engagement in psychiatric services for community-supervised youths and the importance of caregiver factors in designing such interventions.
