Participants in this two-year, single-blind study will be randomly assigned to receive either cognitive therapy combined with enriched care or enriched care alone. Participants will be identified in primary care settings as having experienced suicide ideation in the past month. Cognitive therapy will be provided by Ph.D.-level therapists and will be geared specifically toward older men with suicidal tendencies. The enriched care condition will consist of the usual care that individuals receive for suicide prevention, plus assessment and referral services provided by independent evaluators and study case managers. All participants will be assessed pre-treatment to attain baseline measures of suicide ideation, hopelessness, and depression. Study visits will occur at baseline and Months 1, 3, 6, 12, 18, and 24 to assess suicide ideation. Self-report and clinician-administered measures will be used to assess participants' progress.
