One of the most vulnerable groups is adults 50 years and older. Despite this stage of life is particularly amenable to the implementation of targeted suicide prevention strategies, we have few studies of the efficacy of psychological interventions, those that do exist have methodological limitations, and none were implemented in formats other than face-to-face, which limits their accessibility. There is a need for brief psychological interventions that can be administered in both face-to-face and remote formats, do not require long training periods, and are effective in different contexts: for example, problem-solving therapy. The main objective of this project is to evaluate the efficacy of a brief problem-solving psychological intervention for targeted suicide prevention in people aged 50 years and older, administered in face-to-face, conference call, and smartphone app formats. A randomized controlled trial will be performed. Participants will be recruited through healthcare centers in the Autonomous Community of Galicia (Spain). To be included, participants must: (a) be at least 50 years old, (b) reside in Galicia, and (c) present suicidal ideation. Subjects will be excluded if they: (a) present serious mental health or medical disorders; (b) have begun receiving psychological or psychopharmacological treatment in the previous two months or are participating in other suicide prevention research; (c) do not have an appropriate mobile device or sufficient fluency to communicate in Spanish, or have problems that make it impossible to participate; or (d) plan to move in the next 18 months. At pre-intervention information will be collected on sociodemographic, family, personal history, current suicide risk and other clinical variables. 212 participants will be randomly assigned to (1) a problem-solving-based psychological intervention delivered face-to-face (PSPI-FF; experimental group 1); (2) a problem-solving-based psychological intervention delivered via telephone conference call (PSPI-CC; experimental group 2); (3) a problem-solving-based psychological intervention delivered via a smartphone app (PSPI-A; experimental group 3); or (4) a usual care control group (UCCG). Participants in the experimental groups will complete the six sessions/modules of the interventions. Finally, subjects in all groups will be evaluated at post-intervention and 3, 6 and 12-month follow-ups. conditions: Suicide studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL primaryPurpose: PREVENTION masking: QUADRUPLE whoMasked: PARTICIPANT whoMasked: CARE_PROVIDER whoMasked: INVESTIGATOR whoMasked: OUTCOMES_ASSESSOR count: 212 type: ACTUAL name: Problem-solving-based psychological intervention measure: Change from baseline suicidal ideation to post-treatment (7 weeks), and follow-ups at 6 and 12 months. measure: Change from baseline suicidal ideation to post-treatment (7 weeks), and follow-ups at 6 and 12 months. measure: Change from baseline hopelessness to post-treatment (7 weeks), and follow-ups at 6 and 12 months measure: Change from baseline anxiety and depressive symptoms to post-treatment (7 weeks), and follow-ups at 6 and 12 months measure: Change from baseline reasons for living to post-treatment (7 weeks), and follow-ups at 6 and 12 months measure: Change from baseline impulsivity to post-treatment (7 weeks), and follow-ups at 6 and 12 months measure: Change from baseline problem-solving skills to post-treatment (7 weeks), and follow-ups at 6 and 12 months measure: Change from baseline social support to post-treatment (7 weeks), and follow-ups at 6 and 12 months measure: Change from baseline syndrome of clinical anger to post-treatment (7 weeks), and follow-ups at 6 and 12 months measure: Treatment adherence measure: Satisfaction with the service received measure: Sociodemographic, familial, personal history, and current suicide risk variables sex: ALL minimumAge: 50 Years stdAges: ADULT stdAges: OLDER_ADULT facility: Research Group on Mental Health and Psychopatology city: Santiago de Compostela state: A Coruña zip: 15782 country: Spain lat: 42.88052 lon: -8.54569 hasResults: False
