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.

RECRUITINGColumbia 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: 1 year
Alcohol Use (AUDIT-C)
Three-item self-report questionnaire that screens for hazardous alcohol consumption; higher scores indicate higher risk drinking
Time frame: 1 year
Heaviness of Smoking Index (HSI)
Two-item index derived from cigarettes per day and time to first cigarette; higher scores indicate greater nicotine dependence
Time frame: 1 year
Drug Abuse Screening Test (DAST)
Self-report screening tool for problematic use of non-alcohol drugs; total score reflects severity of drug-related problems
Time frame: 1 year
Difficulties in Emotion Regulation Scale (DERS-18)
Eighteen-item self-report measure of problems in emotion regulation across several domains; higher scores reflect greater difficulties regulating emotions.
Time frame: 1 year
Barratt Impulsiveness Scale (BIS-11)
Self-report questionnaire with 30 items that evaluates different facets of impulsivity (attentional, motor and non-planning); higher total scores indicate greater impulsive traits.
Time frame: 1 year
Health-related Quality of Life (EuroQol-5D)
Standardized questionnaire that assesses health-related quality of life across five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression); higher index values reflect better perceived health.
Time frame: 1 year
UCLA-3 Item Loneliness Scale
Three-item self-report scale that screens for perceived loneliness and social isolation; higher scores indicate greater feelings of loneliness
Time frame: 1 year
Reflective Functioning Questionnaire - RFQ-8
