What this Trial Is About

Suicide is a significant public health issue, especially affecting adults aged 50 and older. This research aims to evaluate the effectiveness of a brief problem-solving psychological intervention designed to prevent suicide in this age group. The study addresses the need for accessible interventions that can be delivered face-to-face, by telephone conference call, or through a smartphone app, expanding options beyond traditional face-to-face therapy. Participants will be randomly assigned to one of four groups: a face-to-face group receiving six weekly 90-minute problem-solving sessions, a telephone conference call group with the same format and duration, a smartphone app group completing six modules of similar content and length, or a usual care group receiving standard psychotherapy or medication as determined by their health providers. The intervention includes training in problem-solving, mood monitoring, relaxation, mindfulness, and coping strategies. Before the intervention, information on demographics, family and personal history, and suicide risk will be collected. Participants will be assessed at post-intervention (7 weeks) and at 3, 6, and 12 months to measure changes in suicidal thoughts, hopelessness, anxiety, depression, reasons for living, impulsivity, problem-solving skills, social support, anger, treatment adherence, and satisfaction. The study will monitor outcomes and safety over this period to evaluate the intervention's impact.
