Interventions (Strategies)	• Quality improvement strategies (e.g., strategies targeting systems and practitioners of mental health care to children and adolescents with the goal of improved quality of care)	Interventions targeting only patients, only drug interventions (although strategies to implement or disseminate drug interventions would qualify), and interventions not otherwise described in inclusion criteria
	• Implementation strategies (e.g., strategies to integrate evidence-based practice (EBP) interventions that meet National Registry of Evidence-based Programs and Practices (NREPP) inclusion criteria with the goal of changing practice patterns)
	• Dissemination strategies (e.g., strategies to enhance the adoption and implementation of evidence-based interventions that meet NREPP inclusion criteria)
Comparator	Any control strategy, including usual care or different variants of the same intervention	None
Outcomes	Intermediate outcomes (at least one intermediate outcome is required for KQs 1, 3)	All outcomes not otherwise specified
	Patient
	• Access to care  • Satisfaction  • Treatment engagement  • Therapeutic alliance with practitioner
	Practitioner
	• Satisfaction with or acceptability of approach  • Protocol adherence/program model fidelity  • Competence or skills
	System or organization
	• Feasibility  • Uptake  • Timeliness  • Penetration  • Sustainability  • Resources (including costs)
	Patient health and service utilization outcomes (at least one of these outcomes is required for KQs 1 and 3 unless the strategy uses an intervention that is an EBP)
	Required:
	• Change in mental health status, including symptom change, response, remission, relapse, and recurrence
	• Coexisting physical health conditions, substance use problems, developmental disorders, other mental health problems
	Not Required:
	• Mortality • Socialization skills and behavior • Functional status • Quality of life • Service utilization (e.g., visits, hospitalizations)
	Harms of strategy
