Dual Assessment of Suicidal Risk: Integrating the Clinician-Administered CHRT-Beh and Self-Report CHRT-SR₉: Findings...

Suicide prevention requires reliable assessment tools, integrating the Food and Drug Administration (FDA)-endorsed Columbia Classification Algorithm of Suicide Assessment domains and psychological risk factors, capturing patient-reported experiences and clinician-reported characterizations of suicidality comprehensively. The 9-item Concise Health Risk Tracking - Self-Report (CHRT-SR₉) is a patient-reported outcome that was designed to capture suicide-related constructs such as pessimism, helplessness, despair, and suicidal thinking/planning. The semi-structured, clinician-administered CHRT-Behavior (CHRT-Beh) scale was created to capture recent suicidal events (ideation and behaviors) in alignment with the FDA-endorsed system for coding suicidality. In this report, we present a two-step approach for assessing suicidality and provide preliminary data for the dual use of the CHRT-SR₉ and CHRT-Beh.

Data from the Texas Resilience Against Depression (T-RAD) cohort were used for the analysis. T-RAD consists of two datasets, one with participants with a history of depression and healthy controls (D2K, n=1040, ages 10 and above) and one with youth ages 10-24 years at risk for depression (RAD, n=365). Participants completed both the CHRT-SR₉ and CHRT-Beh at study entry.

Using the CHRT-Beh, a subset of D2K participants aged ≥ 24 years reported suicidal ideation (14.07%), non-suicidal self-injury (1.11%), and self-injurious behavior (0.28%) in the past week. Findings were similar in D2K participants aged 10-24 years. A subset of RAD participants (1.64%) reported suicidal ideation without attempt or self-injurious behavior in the past week. Participants who reported suicidal ideation on the CHRT-Beh had significantly higher CHRT-SR₉ total scores (17.1 ±7.4 vs 5.6 ±6.2; p<0.0001) and CHRT-SR₉ suicidal ideation subscale scores (4.0 ±3.1 vs 0.6 ±1.7; p<0.0001) than those without suicidal ideation.

The co-administration of CHRT-SR₉ and CHRT-Beh provides researchers with a suicidality risk measure and a retrospective assessment of suicidal behaviors. The CHRT-SR₉ and CHRT-Beh package provides a holistic clinical evaluation of suicidal risk meeting regulatory requirements.
