A Longitudinal Study of Suicidality in a Homeless Population Sample.

This study's findings contradict assumptions that the high prevalence of suicidal symptoms in homeless populations can be explained by the difficulties and miseries of homelessness. Psychiatric illness, substance abuse, and psychosocial factors associated with homelessness may be direct contributors to suicidal symptoms and thus represent strategic intervention targets.HIGHLIGHTSMost suicidality reported at baseline first emerged long before first homelessnessAfter baseline, few reported new suicidal symptoms or had active suicidal symptomsSignificantly fewer reports of suicidal ideation/plans over time were found in those with the most stable housing outcome.
