IS PATH WARM: Mnemonic used to assess the risk of suicide (warning signs):

   I    Ideation (thinking, talking or wishing about suicide)
   S    Substance use or abuse (increased use or change in substance)
   P    Purposelessness (no sense of purpose or belonging)
   A    Anger
   T    Trapped (feeling like there is no way out)
   H    Hopelessness (there is nothing to live for, no hope or optimism)
   W   Withdrawal (from family, friends, work, school, activities, hobbies)
   A    Anxiety (restlessness, irritability, agitation, changes in sleep pattern)
   R    Recklessness (high risk-taking behavior)
   M    Mood disturbance (dramatic changes in mood)

SAD PERSONS: The score is calculated from ten yes/no questions, with points given for each affirmative answer as follows:

   S    Male sex → 1
   A    Age <19 or >45 years → 1
   D    Depression or hopelessness → 2
   P    Previous suicidal attempts or psychiatric care → 1
   E    Excessive ethanol or drug use → 1
   R    Rational thinking loss (psychotic or organic illness) → 2
   S    Single, widowed or divorced → 1
   O    Organized or serious attempt → 2
   N    No social support → 1
   S    Stated future intent (determined to repeat or ambivalent) → 2

This score is then mapped onto a risk assessment scale as follows:

   0-5:  May be safe to discharge (depending upon circumstances)
   6-8:  Probably requires psychiatric consultation
   8-13:  Probably requires hospital admission

Hope this helps!
