What this trial measures

• Adoption of Measurement-Based Care (MBC) strategies4-month (follow-up 2)

  Clinicians will complete weekly caseload service logs, that document whether each of the 3 core MBC practices (i.e., measure administration, clinician reviewing results, discussing results with patient to support collaborative treatment planning) were used with each identified patient in their caseload. MBC adoption (client level) will be a binary measure for each youth on the clinicians' caseload-evidence of any MBC practice will be considered adoption. This is a longitudinal outcome that will be collected on a weekly basis to allow for the observation of growth over time.

• Penetration or saturation of Measurement-Based Care (MBC) strategies use4-month (follow-up 2)

  Clinicians will complete weekly caseload service logs, that document whether each of the 3 core MBC practices (i.e., measure administration, clinician reviewing results, discussing results with patient to support collaborative treatment planning) were used with each identified patient on their caseload. MBC penetration will be derived from dividing the number of youths on the clinician's caseload who is receiving any MBC practices by the total number of youths on the caseload, which should yield a percentage score.

• Sustainment of Measurement-Based Care (MBC) strategies use4-month (follow-up 2)

  Clinicians will complete weekly caseload service logs, that document whether each of the 3 core MBC practices (i.e., measure administration, clinician reviewing results, discussing results with patient to support collaborative treatment planning) were use with each identified patient on their caseload. MBC sustainment will be indicated by the change in MBC penetration at 1 months post-training (Follow-Up 1) and 3 months post-training (Follow-Up 2).

• Fidelity of Measurement-Based Care (MBC) Strategies use4-month (follow-up 2)

  Clinicians will complete weekly caseload service logs, that document whether each of the 3 core MBC practices (i.e., measure administration, clinician reviewing results, discussing results with patient to support collaborative treatment planning) were used with each identified patient on their caseload. Fidelity will be measured by percentage of a clinician's caseload with whom all 3 MBC core components were reported on their caseload service logs.

• Change in Clinician's Implicit Association Test (IAT) Scores0-months (Pre-training), 1-month (post-training), 2-month follow-up 1, and 4-month (follow-up 2)

  The Implicit Association Test (IAT), the most well-established measure of implicit racial attitudes with over 20 years of empirical support, is a computer-based reaction time task that measures the relative strength of association between pairings of two groups with two evaluative attributes (e.g., White-good and Black-bad vs White-bad and Black-good). The difference in reaction time between the two pairings would reveal the respondent's relative bias. Clinicians will complete 4 distinct IATs (via the online surveys) at each data collection timepoint. The IATs will measure (1) implicit prejudice toward Black (2) and Latinx youth (both in comparison to White youth), (3) implicit stereotyping of Black youth as aggressive compared to White youth (peaceful), and (4) implicit stereotyping of Latinx youth associated with academic failure and White youth with academic success.

• Change in Clinician and Youth Working Alliance Inventory--Short Form scores1-month (post-training), 4-month (follow-up 2)

  Working Alliance Inventory--Short Form is a 12-item clinician- and patient-report rating scale of the therapeutic relationship with items that capture agreement on the goals and tasks of therapy as well as the therapeutic bond. It has been validated for use with youth 11-18 years old, demonstrating excellent internal consistency (α = 0.93 to 0.96) for both youth and clinician rating forms, and evidencing a single factor structure.

• Change in Strengths and Difficulties Questionnaire (SDQ) youth and caregiver report scores1-month (post-training), 4-month (follow-up 2)

  The Strengths and Difficulties Questionnaire (SDQ) is a 25-item self- and informant-reported symptom questionnaire that has been validated for use with youths ages 4-18 (self-report for 11-18+) with 5 subscales (emotional distress, conduct problems, attention, peer relationships, prosocial behaviors). Internal consistency for these subscales is adequate, ranging from α = .78 to .82. An additional 5 items comprise an "impact scale" that assesses the degree to which youth's symptoms interfere with different domains of functioning. The impact and prosocial subscale scores will serve as our measures of functional impairment. The SDQ has demonstrated strong psychometrics in large-scale studies with US and international samples and has been shown to be sensitive to treatment change. Spanish versions have been validated with evidence of similar factor structure, measurement invariance, and adequate internal consistency for both youth and parent report, α = .71 to .75.
