Brief Problem-solving Intervention in Different Formats for the Prevention of Suicide in Adults Over 50

The intervention will include training in the components of the problem-solving model and other behavioral and cognitive skills such as detecting warning signals, monitoring mood, relaxation techniques, self-reinforcement, strategies for acting in crisis situations, engaging in enjoyable activities, mindfulness meditation techniques, or strategies for reframing irrational thoughts. It will be developed from the problem-solving model (D'Zurilla and Nezu, 1982) and will reference the indicated prevention program for depression (Vázquez et al., 2015), which has shown efficacy in reducing depressive symptoms and preventing the onset of depression episodes (Otero et al., 2015; Vázquez et al., 2013), with results on symptomatology maintained at 8 years (López et al., 2020); and the indicated prevention intervention that demonstrated efficacy in reducing suicide risk (Xavier et al., 2019).
