Problem-solving therapy for suicide prevention in adults over 50

This trial is testing a brief problem-solving therapy program designed to help prevent suicide in adults age 50 and older. The same therapy will be offered in three different formats — in-person groups, phone calls, or a smartphone app — so researchers can see which works best and which is easiest for people to access. The study compares these therapy formats to usual care to see if this focused, short-term approach actually reduces suicidal thoughts and behaviors.

Suicide is a major public health crisis, and adults over 50 are at especially high risk. While problem-solving therapy has shown promise for suicide prevention, very few studies have tested it in older adults, and most require face-to-face visits which aren't accessible to everyone. This trial aims to fill that gap by testing whether this treatment works in formats that are easier to reach — like phone calls and apps — and can be delivered quickly without requiring extensive therapist training.
