Abstract

OBJECTIVE:

We report on the prevalence of suicidal thoughts and behaviors in Spanish university students and their risk and protective factors (distal/proximal; individual/environmental).

METHODS:

First-year university students completed an online survey including Self-Injurious Thoughts and Behaviors Interview (SITBI) items, the screening version of the Columbia-Suicide Severity Rating Scale (C-SSRS) along with adversities and positive relationships during childhood/adolescence, recent stressful experiences, and lifetime mental disorders. Nested logistic regression models were estimated and areas under the curve (AUC) compared.

RESULTS:

A total of 2,118 students completed the survey (mean age = 18.8 [SD = 1.4] years; 55.4% female). Twelve-month prevalence of suicide ideation (SI) was 9.9%, plans, 5.6%, and attempts, 0.6%. Risk factors of 12-month SI were as follows: parental psychopathology (OR = 1.7, 95% CI 1.2-2.5); sexual assault (OR = 5.6, 95% CI 1.4-22.1); lifetime mood disorder (OR = 5.2, 95% CI 3.5-7.7); and lifetime anxiety disorder (OR = 1.7, 95% CI: 1.1-2.5). Childhood positive relationships protected from SI were as follows: peers/others (OR = 0.6, 95% CI 0.4-0.9 for the second highest tertile) and family (OR = 0.4, 95% CI 0.3-0.7 for the highest tertile). AUC of the final model was 0.82 (SE = 0.015).

CONCLUSION:

Our results indicate a high prevalence of SI among Spanish university students and identify protective and risk factors from a comprehensive conceptual model.
