Key provisions used in wiki

  • Defines a 7-level severity framework for classifying suicidal ideation, from wish to die through active ideation with specific plan and intent
  • Gold standard instrument for crisis classification, adopted by the FDA, VA, DoD, and multiple state legislatures (including CA SB 243)
  • Provides the clinical foundation for InvisibleBench crisis-detection scenarios that test whether AI systems recognize and appropriately escalate ideation signals
  • Distinguishes between passive ideation (wish to die) and active ideation (plan, intent, method), requiring different response urgencies
  • Enables standardized severity scoring that maps directly to InvisibleBench crisis-gate evaluation criteria
