An observational study in Suicidal Behaviors, sponsored by Parc de Salut Mar. Recruiting at 2 sites in Spain. Open to participants aged 12 Years and older. Per ClinicalTrials.gov, last updated 2026-04-28.
Sponsored by Parc de Salut Mar · Observational
The goal of this observational study is to learn more about people who come to emergency departments in Spain after a suicide attempt and to find ways to prevent another attempt. The main questions are whether some personal, social, biological, and clinical factors are linked to a higher risk of trying again, and whether different follow-up strategies can help lower this risk over time.
Researchers will follow a total of about 3,600 people who attempted suicide: around 1,800 who were already recruited in a previous study and about 1,800 new participants who will be added in this project, in several hospitals across Spain.
Some participants may also be invited to give blood samples, answer online questionnaires, or use smartphone-based tools to understand better changes in mood and suicidal thoughts in daily life. A subset of participants may be invited to join separate clinical trials that test different follow-up programs to prevent another suicide attempt; these trials will be registered and described in their own study records.
BACKGROUND: Suicide is the leading preventable cause of death in the world. In Spain, the data show a growing trend in recent years, indicating the need to implement evidence-based prevention strategies. OBJECTIVES: The main objective of this study is to continue monitoring a previously established cohort of 1,800 suicide attempts and extend it to include 3,600 cases. The secondary objectives are: 1) to identify risk factors (1a: socioeconomic, psychological, and clinical, 1b: biological, and 1c: genetic) that can predict a repeat attempt, 2) to study suicidal behavior in the pandemic and post-pandemic times, 3) to identify phenotypes related to suicidal ideation and behavior using momentary ecological assessment and 4) to determine the efficacy of secondary prevention programs for suicidal behavior compared with treatment as usual (TaU). METHOD: Multi-center-coordinated cohort study with five nested clinical controlled trials. The participants will be recruited in nine centers distributed in the Spanish territory. The primary variable will be the time to repeat the attempt.
SUB-PROJECT 1: a) long-term follow-up study (5 years) of a cohort of suicide attempts (total n = 3600 cases), b) study of biological and c) genetic markers associated with a suicide attempt. SUB-PROJECT 2: will study suicidal ideation and behavior phenotypes using momentary ecological assessment and experience sampling. SUB-PROJECT 3: will evaluate the efficacy of different secondary prevention programs compared to TaU.

Individuals (adolescents and adults) who present to the emergency departments of participating hospitals in Spain after a suicide attempt. The study will follow approximately 3,600 participants (about 1,800 already enrolled in a previous cohort and about 1,800 newly recruited) for up to 3 years to examine suicidal behavior and related risk and protective factors

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Adults and adolescents who present to participating Spanish hospitals after a suicide attempt and are enrolled in the SURVIVE cohort. This group includes about 1,800 participants from a previous study and about 1,800 newly recruited participants, all followed for up to 3 years.
Columbia Suicide Severity Rating Scale (C-SSRS)
The Columbia-Suicide Severity Rating Scale (C-SSRS) is a brief, structured interview that uses simple questions about suicidal thoughts and behaviors to identify whether someone is at risk for suicide and how severe and urgent that risk is.

Time frame: Baseline
Plan to share: No — Individual participant data (IPD) will not be shared because the dataset includes highly sensitive information on suicidal behavior collected in a limited number of centers, which increases the risk of re-identification even after de-identification. Data sharing is therefore restricted to protect participant privacy and comply with ethical and regulatory requirements.
