This NIMH R34 award application proposes to conduct an adaptation, implementation, and pilot testing of the culturally centered CBT protocol, the Socio-Cognitive Behavioral Therapy for Suicidal Behaviors (SCBTSB), among suicidal youth in Mexico City, Mexico.

The research plan will (a) culturally adapt and contextualize the SCBT-SB for its implementation in the Mexican public health system, (b) pilot test the protocol through an RCT (SCBT-SB vs TAU; 60 patients and caregivers) and (c) evaluate the implementation process of the SCBT-SB and assess qualitatively possible factors that may promote or hinder its future uptake.

This R34 application proposes to conduct an adaptation, implementation, and pilot testing of the culturally centered CBT protocol, the Socio-Cognitive Behavioral Therapy for Suicidal Behaviors (SCBT-SB), among suicidal youth in Mexico City, Mexico. SCBT-SB is a psychosocial treatment developed with the support of the NIMH specifically for suicidal Hispanic youth. SCBT-SB is available in Spanish, has an established training model, and has yielded promising results in intent to treat analyses in reducing suicide attempts and depressive symptoms in comparison to treatment as usual (TAU). Furthermore, it is the CBT protocol with the most empirical evidence for Latinx youth with suicidal behaviors. SCBT is attuned to the cultural needs of Hispanic suicidal youth in real-world service settings. The "EPIS" implementation framework (Exploration, Preparation, Implementation, and Sustainment) and the Ecological Validity Model (ECV) will guide the SCBT-SB implementation and cultural adaptation into the Mexican culture and mental health system. The study will be conducted in one of the main public hospitals in Mexico City, the Hospital Psiquiatrico Infantil "Dr. Juan N. Navarro". In line with this objective, the following research aims are proposed: Aim 1: Adapt the SCBT-SB for its implementation and pilot testing in the Mexican public health system. An open trial with 10 participants will be completed as part of the adaptation process before the pilot randomized controlled trial (RCT). Aim 2: To conduct a pilot RCT to assess feasibility, acceptability, and treatment effect of SCBT-SB in clinical outcomes versus treatment as usual (TAU). Participants will be 60 youth ages 12-17 admitted to the inpatient units receiving services for suicidal thoughts and behavior (STB). STB and depressive symptoms will be examined at baseline, at hospital discharge (approximately 2 weeks), six-, and 9-months following baseline. Aim 3: To identify organizational/system-level, provider-level, and client factors that may promote or hinder uptake of the new intervention in the public system.

Youth Inclusion Criteria:

• ages 12 to 17,
• severe SI, defined as a score of 22 or above on the SIQ-JR or having made a SA or having a suicidal crisis (e.g., threats of attempting suicide) within the last 3 months
• not be engaged in mental health services outside HPIJNN.

Exclusion Criteria:

• having a diagnosis of a psychotic disorder
• having a diagnosis of substance use disorder, rated severe on the DSM-593 (i.e., endorsement of 6 or more symptoms),
• not having sufficient cognitive ability to enter a psychotherapy service (whether reported by the parents or by data in the clinical record)

Basic demographics and outcome measures will be uploaded to the NIMH Data Archive with a data dictionary.

Data will be available starting 6 months after main study results publication.

Researchers with access to the NIMH Data Archive will have access to the uploaded data. Data will also be made available to other researchers by request through a Data Sharing Agreement between institutions and as per NIH data sharing guidelines. The PI will also consult to anyone interested in replicating the intervention and study.
