Brief Summary

Suicide represents a personal tragedy and an enormous global public health problem. 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.

Outcome Measures

Primary Outcomes (2)

  • Change from baseline suicidal ideation to post-treatment (7 weeks), and follow-ups at 6 and 12 months.

    Suicidal ideation will be assessed using the Suicidal Ideation Scale (SSI; Beck et al., 1979), a semi-structured scale of 19 items with an internal consistency (Kuder-Richardson coefficient \[KR-20\]) of .89 and an inter-rater reliability (k) of .83.

    Pre- and post-intervention (7 weeks) with follow-ups at 3, 6 and 12 months

  • Change from baseline suicidal ideation to post-treatment (7 weeks), and follow-ups at 6 and 12 months.

    Aditionally, the severity of ideation and suicidal behavior over the last month will be assessed using the Columbia Scale for assessing suicide risk (C-SSRS; Posner et al., 2011). It consists of a semi-structured interview with good convergent and discriminant validity and high sensitivity (100.0%) and specificity (99.4%) for the classification of suicidal behavior; the ideation intensity subscale showed a Cronbach's alpha of .73-.95.

    Pre- and post-intervention (7 weeks) with follow-ups at 3, 6 and 12 months

Secondary Outcomes (9)

  • Change from baseline hopelessness to post-treatment (7 weeks), and follow-ups at 6 and 12 months

    Pre- and post-intervention (7 weeks) with follow-ups at 3, 6 and 12 months

  • Change from baseline anxiety and depressive symptoms to post-treatment (7 weeks), and follow-ups at 6 and 12 months

    Pre- and post-intervention (7 weeks) with follow-ups at 3, 6 and 12 months

  • Change from baseline reasons for living to post-treatment (7 weeks), and follow-ups at 6 and 12 months

    Pre- and post-intervention (7 weeks) with follow-ups at 3, 6 and 12 months

  • Change from baseline impulsivity to post-treatment (7 weeks), and follow-ups at 6 and 12 months

    Pre- and post-intervention (7 weeks) with follow-ups at 3, 6 and 12 months

  • Change from baseline problem-solving skills to post-treatment (7 weeks), and follow-ups at 6 and 12 months

    Pre- and post-intervention (7 weeks) with follow-ups at 3, 6 and 12 months

Study Arms (4)

Problem-solving-based psychological intervention delivered in a face-to-face format (PSPI-FF)

EXPERIMENTAL

Participants in this group will receive a problem-solving intervention for suicide prevention in a face-to-face format. The intervention will consist of 6 sessions, approximately 90 minutes in duration each, once a week, in a group format, in person.

Behavioral: Problem-solving-based psychological intervention

Problem-solving-based psychological intervention delivered via telephone conference call (PSPI-CC)

EXPERIMENTAL

Participants in this group will receive the intervention described in a teleconference call format, with the same duration, contents, and structure.

Behavioral: Problem-solving-based psychological intervention

Problem-solving-based psychological intervention delivered via a smartphone app (PSPI-A)

EXPERIMENTAL

Participants in this group will receive the intervention described adapted to be administered through a smartphone app, with equivalent duration, content, and structure (approximately 90 minutes to complete each of the 6 modules).

Behavioral: Problem-solving-based psychological intervention

Usual care (UCCG)

NO INTERVENTION

Participants in this group will receive usual care. Usual treatment will include individual and group psychotherapy and/or psychiatric medication as determined by the health professionals they are currently consulting, whether in public or private facilities.

Interventions

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).
