CAMS is a clinical intervention designed to modify how clinicians engage, assess and plan treatment with suicidal patients. The foundational brief intervention that all participants will receive includes 1 90-minute session of CAMS assessment and planning interview with follow-up care navigation.

Specific skills are taught to youth based on CAMS drivers/case conceptualization of suicidality. Based on our pilot work, the common components of treatment include explicit coaching in skills informed by evidence-based treatments like Dialectical Behavior Therapy (DBT), Cognitive Behavioral Therapy (CBT), and Behavioral Activation (BA). Skills are drawn from the following 3 domains: emotion regulation and crisis survival skills (e.g., paced breathing, use of temperature and exercise to alter mood, Hope Box), behavioral activation strategies (e.g., goal-directed behavior, scheduling of activities, problem-solving) and communication skills (communication around suicidality, validation of self and others, making clear requests/DEAR MAN). Youth assigned to the Ongoing CAMS Intervention condition will receive three, 50-minute sessions that include the interim SSF and driver focused treatment encompassing skills instruction, in-session practice, and assigned homework.

Caregivers will receive 3, 30-minute modules across 3 sessions that provide explicit coaching in several skills. Module content will include 1) psychoeducation on suicidality and the escalation cycle and creation of a communication plan related to responding to youth suicidality (i.e., Crisis Escalation and Communication Plan); 2) positive communication and relationship building strategies including reflective listening, validation, and how to implement regular teen-directed one-on-one time; and 3) setting up behavioral expectations, house rules, and using positive reinforcement based contingency management in the home (i.e., targeted praise, using rewards to promote more effective behaviors). All modules will include didactic skill building, role-play of skill use with the therapist, and a check-in with the youth and youth therapist to collaboratively problem-solve barriers to use of skills.

CAMS is a clinical intervention designed to modify how clinicians engage, assess and plan treatment with suicidal patients. The foundational brief intervention that all participants will receive includes 1 90-minute session of CAMS assessment and planning interview with follow-up care navigation. CAMS is based around a model of STB which states that youth become suicidal in response to overwhelming pain, and treatment identifies and targets the drivers of suicide as the primary focus of assessment and intervention.

This measure assesses the frequency of suicidal ideation on a 5-point Likert scale, with 0 indicating "never" and 4 indicating "most or all of the time". Higher scores reflect higher severity and frequency of suicidal ideation.

ASuicidal thoughts and behaviors. Suicide ideation is rated on a scale of 1 to 5, with higher numbers reflecting more severe ideation. Suicidal behaviors are count measures, with higher numbers reflecting more attempts.
