Modelo de riesgo suicida transcultural: Evidencias de la capacidad predictiva en dos países de Latinoamérica

Abstract

Introduction: The prevalence of suicide risk among countries such as Colombia and Mexico, has increased over the years, and parsimonious models with favorable explanatory capacity are required. Objective: To develop a suicide risk model with a cross-cultural predictive capacity based on the clinical variables such as depression, hopelessness, and suicidal ideation, in two Latin American countries. Materials and Method: There was a final sample of 807 Mexican and Colombian adults, 278 men, and 531 women. Scales of hopelessness (IDIS), suicidal ideation (PANSI and IDIS), depression (SDS), and suicidal risk (SRS), were used. Two predictive hypotheses were tested: a) depression is associated with hopelessness and suicidal ideation in the same way in both countries, and b) suicidal ideation predicts suicide risk and is associated with depression and hopelessness. Results: The findings indicated high and significant correlations between the predictor and criterion variables. The model obtained showed a total explained variance of 67% of the suicide risk and 66% for each country. Conclusions: It was verified that the model was invariant between the samples of the two participating countries, which represented new evidence of the cross-cultural utility of the model obtained based on cognitions and affect on suicidal behavior.
