PATH 2 Purpose: Primary Care and Community-Based Prevention of Mental Disorders in Adolescents

Time will be measured to nearest minute for all intervention related activities including initial screening, engagement phone calls, use of CATCH-IT, TEAMS group activities, including travel time to and from TEAMS groups. Time will be measured from adolescent, family, practice, community center, healthcare organization, health system perspective. For time that cannot be directly measured by study staff, the investigators will sample direct observation or questionnaires to capture time required for health system related activities such as screening and engagement.

Cultural acceptability for each stakeholder using appropriate, validated instruments. Adolescent and family: Usefulness, Satisfaction, and Ease Questionnaire (USE, 30 items, self-report, 7-point Likert scale, 30-210 score range, higher score indicates more acceptable). An example statement is: "I would recommend this to a friend."

Costs will be measured for all stakeholders. For practice, community center, healthcare organizations, health systems, cost will be measured to nearest dollar by converting time measures into employment related costs based on mean wages an benefits for staff at that occupational level. Adolescent and family costs will be measured by converting time into mean hourly wages and benefits for adolescent and family members involved in the project (based on mean wage for age and occupation).

Mini-International Neuropsychiatric Interview for Children and Adolescents (MINI Kid, self-report). This is a structured psychiatric interview administered by a trained staff member which uses stem questions and follow-ups to determine the presence of symptoms and date of onset. The staff member then determines if and when the symptoms developed an episode is present. Measure is either episode present or not and date of onset.

The Socio-Cultural Relevance Scale (10-item and 14-item versions, self-report, 5-point Likert scale, 10-40 or 14-56 score ranges, higher score indicates greater socio-cultural relevance) will assess perceived change and satisfaction with the intervention, component of cultural acceptability to adolescent)

Organizational Readiness to Change Assessment (ORCA, 18 questions, 4 items per question, self-report, 5-point Likert scale, 18-90 score range, higher score indicates higher organizational readiness, component of cultural acceptability to practice, community center, healthcare organizations, health systems)

Program Sustainability Assessment Tool (PSAT, 8 questions, self-report 5 items per question, 7-point Likert scale, 8-56 score range, higher score indicates higher capacity for program sustainability, component of cultural acceptability to practice, community center, healthcare organizations, health systems)

Acceptability of Intervention Measure (AIM, 1 question with 4 items, self-report, 5-point Likert scale, 1-5 score range, higher score indicates greater acceptability of intervention, to be completed by all staff and leadership, repeatedly, component of cultural acceptability to practice, community center, healthcare organizations, health systems)

Feasibility of Intervention Measure (FIM, 1 question with 4 items, self-report, 5-point Likert scale, 1-5 score range, higher score indicates greater feasibility of intervention, to be completed by all staff and leadership, repeatedly, component of cultural acceptability to practice, community center, healthcare organizations, health systems)

Intervention Appropriateness Measure (IAM, 1 question with 4 items, self-report, 5-point Likert scale, 1-5 score range, higher score indicates greater appropriateness of intervention, to be completed by all staff and leadership, repeatedly, component of cultural acceptability to practice, community center, healthcare organizations, health systems)

Patient Health Questionnaire-Adolescent (PHQ-A, 9 items plus 4 follow-up items, self-report, 3-point Likert scale, 0-27 score range, higher score indicates more depression symptoms/severity)

Disruptive Behavior Disorders Rating Scale-Adolescent (DBD-A, 41-items, self-report, 4-point Likert scale, 0-123 score range, higher score indicates greater externalizing symptoms)

Screen for Child Anxiety Related Disorders (SCARED, 41-items, self-report, 3-point Likert scale, 0-82 score range, higher score indicates greater anxiety symptoms)

Car, Relax, Alone, Forget, Friends, Trouble substance use assessment (CRAFFT, 6 items, self-report, 2-point scale, 0-6 score range, higher score indicates greater substance abuse symptoms)

Child Post Traumatic Symptoms Disorder Scale (24-items, self-report, 4-point Likert scale, 0-72 score range, higher score indicates greater PTSD symptom levels)

Tendency towards rumination will be assessed by the Children's Response Style Scale (CRSS, 10-items, self-report, 5-point Likert scale, 0-50 score range, higher score indicates greater rumination (more repeated negative thinking, less resilient, component of resiliency)

The Dysfunctional Attitude Scale (DAS, 9-item, self-report, 7-point Likert scale, 9-63 score range, higher score indicates more dysfunctional attitude, less resiliency, component of resiliency)

Child Report of Parental Behavior Inventory (CRPBI, 30-item, self-report, 3-point Likert scale, 0-60 score range, higher scores indicate more positive parent child relationship).

Measured in millimeters of mercury

Calculated by measuring height (centimeters) and weight (kilogram) to calculate kg/meters squared (BMI, Body Mass Index)

Measured in kilograms by standard medical office scale, fully clothed participant

Measure by standard medical office practice measure, without shoes, in centimeters

With the addition of a second cohort to be recruited through a public health media campaign, we will compare results between groups in each arm, and between the two recruitment models. We will compare implementation and clinical outcomes in the same trial arm, but also across the two recruiting methods.

Consolidated Framework for Implementation Research (CFIR) will be used to explore experience of the study from the perspective of 25 stakeholders

We will examine factors related to the COVID-19 pandemic that may be moderators of study outcomes: (1) COVID-19-related behaviors and consequences (e.g. social distancing, sheltering-in-place, family illness and death), and (2) Social determinants of health (e.g. food insecurity, internet access, unemployment) in both cohorts using the Holliston at-Home Questionnaire (a 26-item, adolescent self-report, 5-point Likert scale, 0-150 score range, higher score indicates greater externalizing symptoms).
