“…Spanish version of the SOI-30 reported a Cronbach's alpha reliability index of .89. In Colombia it has been used with university population, showing an internal consistency with Cronbach's alpha of .89 (Arango-Tobón et al, 2021;Gómez & Montalvo, 2021). The internal consistency for this study was .932 (Cronbach's alpha) and .93 (McDonald's Omega).…”

“…In Colombia, findings have not been consistent on the psychological risk variables for suicidal orientation, possibly because there has been a tendency to rely on descriptive theories rather than explanatory models about this phenomenon (Benavides Mora et al, 2019). Nevertheless, some studies highlight that impulsivity could play an important additional predictor role (Arango-Tobón et al, 2021;Bedoya Cardona & Montaño Villalba, 2016;Gómez et al, 2020;Gómez Tabares et al, 2019;Nock et al, 2008).…”

The aim of this research was to describe the effect of depression, hopelessness, and impulsivity on orientation to suicide and the role of impulsivity as a mediator of suicidal orientation in university students with a history of self-injury behaviors. 1645 young people between 18 and 29 years old participated, from two Colombian cities. 218 young people were selected (M= 21.00; SD= 2.99) who reported at least one suicide attempt in the last year, who answered the “Suicidal Orientation Inventory”, the “Beck Hopelessness Scale”, the “Beck Depression Inventory” and the “Barratt Impulsivity Scale”. Depression, hopelessness, and impulsivity explained 63% of the variation in suicidal orientation (R2= .635, IC 95% [.555, .713], p= .001). Impulsivity mediated with depression in those cases in which suicidal orientation was high, whose total, direct and indirect effects were statistically significant (p< .001). Impulsivity plays a mediating role between depression and hopelessness in predicting suicidal orientation.

“…The combination of depression severity and impulsivity may intensify suicidal ideation. Arango-Tobón et al [ 21 ] also emphasized that impulsivity is a significant risk factor for suicide, particularly in individuals experiencing depressive symptoms and hopelessness. Furthermore, prospective studies have found that depression, mediated by hopelessness, contributes to suicidal ideation [ 22 ].…”

Background Close relationships have been observed among impulsivity, depression, hopelessness, and suicidal ideation in depressed patients. However, the precise mechanism that connects these psychological symptoms remains unclear. This study aims to explore the mediation effect of depression and hopelessness on the relationship between impulsivity and suicidal ideation in depressed patients. Methods A total of 258 depressed patients were evaluated using the Hamilton Depression Scale, the Beck Hopelessness Scale, the Scale for Suicide Ideation, and the Barratt Impulsiveness Scale. A path analysis was afterwards performed to determine the specified relationships in the proposed model. Results The relationship between impulsivity and suicidal ideation was found to be serially mediated by depression and hopelessness. The mediating effect of depression and hopelessness accounted for 26.59% of the total effect. Specifically, in the pathway from impulsivity to hopelessness, the mediating effect of depression accounted for 40.26%. Moreover, the relationship between impulsivity and suicidal ideation was mediated by hopelessness, with the mediating effect accounting for 12.41%. It is important to note that these relationships were observed to be independent of age and marital status. Furthermore, the proposed model demonstrated a good fit with the data. Conclusions This study identified a serial mediation pathway between impulsivity and suicidal ideation, mediated by depression and hopelessness. Our findings indicate that impulsivity indirectly influences suicidal ideation through its association with depression, which subsequently contributes to feelings of hopelessness. These results emphasize the importance of addressing symptoms of depression and hopelessness in the prevention and intervention efforts targeting individuals with depression. Additionally, monitoring and addressing impulsivity levels may also be crucial in reducing the risk of suicidal ideation among this population. These findings provide valuable insights for future preventive programs and interventions aimed at mitigating suicidal ideation in individuals with depression.

“…Se han encontrado relaciones entre ideación suicida persistente y problemas de salud mental como depresión, consumo de sustancias psicoactivas y problemas de regulación emocional (Aparicio Castillo & Blandón Rodríguez, 2020;Gomes et al, 2022;Mars et al, 2019). También se ha hallado que la impulsividad se constituye en un factor de alto riesgo en la progresión del plan al intento suicida (Arango Tobón et al, 2021).…”

El objetivo del presente estudio bibliométrico consistió en analizar la producción científica acumulada sobre los factores de riesgo biopsicosocial conducentes al suicidio en la infancia y la adolescencia mediante la implementación de la teoría de grafos. Se consultaron las bases de datos Scopus (Elsevier) y Web of Science, y el análisis se efectuó en bibliometrix, Sci2 tool y Gephi. Se encontraron 2,058 registros. El análisis mostró una red de citaciones de 2,905 registros y cuatro clústeres principales. Los resultados arrojaron una estructura de red de la producción de conocimiento en cuatro tendencias de investigación: (1) factores de predicción de tipo psiquiátrico del comportamiento suicida en niños y adolescentes; (2) asociación entre conducta autolesiva no suicida y comportamiento suicida en adolescentes; (3) relación entre maltrato infantil y suicidio; (4) uso de antidepresivos en la niñez y adolescencia y comportamiento suicida. Finalmente, se plantean consideraciones para la prevención del suicidio en la población objeto de estudio.
