IS PATH WARM?
Psychiatric literature has mixed reviews of the value of the mnemonic. Several studies have found that some of the warning signs are associated with having thoughts about suicide.  A study compared 215 postings on an online "suicide forum" with 94 postings on a "self-injury forum". They found that posters in the 'suicide forum' were more likely than those in the 'self-injury forum' to express thoughts about suicide, purposelessness, feeling trapped, and social withdrawal. The comparison also found that this is not true for recklessness, people in the self-injury forum were more likely to be reckless. The study said that individuals who show "IS PATH WARM" warning signs were more likely to have suicidal ideation.
