A Study to Assess the Validation and Mapping of the Suicide Ideation and Behavior Assessment

The Clinical Global Impression - Severity of Suicidality - Revised (CGI-SS-R) was derived from the Clinical Global Impression Severity Scale (CGI-S), a global rating scale that gives an overall measure of the severity of a participants illness. The CGI-SS-R rating is scored on a 7-point scale from 0 (normal, not at all suicidal) to 6 (among the most extremely suicidal participants).

CGI-SR-I describes aspects of participant's suicidal thinking, behavior and related contributory/protective factors, what is best clinical judgment of participant's imminent risk for suicide within the next 7 days. Scale indicates: 0 (No imminent suicide risk), 1 (Minimal imminent), 2 (Mild imminent), 3 (Moderate imminent), 4 (Marked imminent), 5 (Severely imminent), 6 (Extreme imminent).

CGI-SR-I describes aspects of participant's suicidal thinking, behavior and related contributory/protective factors, what is best clinical judgment of participant's imminent risk for suicide (that is, they will likely end their life by suicide sometime in the future). Scale indicates : 0 (No suicide risk in the long term), 1 (Minimal suicide risk), 2 (Mild suicide risk), 3 (Moderate suicide risk), 4 (Marked suicide risk), 5 (Serious suicide risk), 6 (Extreme risk).

Frequency of Suicidal Thinking describes the clinician determined estimate of the frequency of the participant's suicidal thinking (The FoST rating is scored on a 6-point Likert scale : 0 (Never), 1 (Rarely), 2 (Sometimes), 3 (Often), 4 (Most of the time), 5 (All of the time).

C-SSRS is a clinician rated assessment of suicidal behavior and / or intent. Scale consists of 28 items in 4 sections: suicide behavior, actual attempts, suicidal ideation, and intensity of ideation. Suicidal ideation consists of 5 'yes/no' items: wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods (not plan) without intention to act, active suicidal ideation with some intent to act without specific plan, active suicidal ideation with specific plan and intent. Only items with yes responses are listed. Worsening of suicidal ideation was an increase in severity of suicidal ideation from baseline.

The S-STS CMCM is a multi-item scale that can be administered either by a clinician or patient through self-report. Each item in the S-STS CMCM patient self-report suicide phenomena section (14 items) is scored on a 5-point Likert scale : 0 (not at all), 1 (a little), 2 (moderately), 3 (very), and 4 (extremely).

Patient-reported dynamic suicide risk and protective characteristics (My Risk/Protective Factors) will be assessed based on Suicide Ideation and Behavior Assessment Tool (SIBAT) with up to 31 items that best describes how participant have acted or felt in the past 7 days in terms of responses (Never, Rarely, Sometimes, Often, Most of the time, All the time). This best describes how participants are thinking or feeling right now in terms of Strongly Disagree, Disagree, Slightly Disagree, Slightly agree, Agree, Strongly Agree.

Patient-reported current suicide ideation (My current thinking) will be assessed based on SIBAT with 48 items. The best describes how participants are thinking or feeling right now in terms of Strongly Disagree, Disagree, Slightly Disagree, Slightly agree, Agree, Strongly Agree.
