Abstract
The presence of 10 warning signs for suicide proposed by the American Association of Suicidology was compared in 215 postings on a suicide forum and 94 postings on a self-injury forum. The suicide forum postings received a higher score on the 10 signs than the self-injury forum postings, and significant differences were found for 6 of the 10 signs: suicidal ideation, purposelessness, trapped, hopelessness, withdrawal, and, in the reverse direction, recklessness. Overall, the findings support the usefulness of the warning signs in identifying suicidal individuals.
