Columbia-Suicide Severity Rating Scale (C-SSRS) Assessing Suicidal Ideation and Behaviour using 5-Point Scales156 weeksA clinician-rated instrument that reports the severity of both suicidal ideation and behavior. Suicidal ideation is classified on a 5-item scale: 1 (wish to be dead), 2 (nonspecific active suicidal thoughts), 3 (active suicidal ideation with any methods \[not plan\] without intent to act), 4 (active suicidal ideation with some intent to act, without specific plan), and 5 (active suicidal ideation with specific plan and intent). Suicidal behavior is classified on a 5-item scale: 0 (no suicidal behavior), 1 (preparatory acts or behavior), 2 (aborted attempt), 3 (interrupted attempt), and 4 (actual attempt). More than 1 classification can be selected provided they represent separate episodes. (Minimum total score 0, maximum total score 5; higher total scores indicate more suicidal ideation and/or suicidal behavior)
