Background: Identifying accurate methods of assessing suicidal ideation has important implications. The lack of a universal definition of suicidal ideation has complicated measurement efforts. This study details the development of a brief self-report measure of suicidal ideation which specifically focuses on thoughts of suicide. Method: The Questionnaire for Suicidal Ideation (QSI) was developed by collating items from three existing measures of suicidal ideation. Items explicitly describing acts or behaviours were removed and Posner et al.’s (2007) definition of suicidal ideation was applied to the remaining items. The final questionnaire consisted of 6 items. Participants were adults (n = 192) and adolescents (n = 152) attending community mental health services in the Irish public health service. Results: The QSI demonstrated excellent reliability in adult (α = .91) and adolescent (α = .90) samples. Exploratory factor analysis produced a one-factor solution explaining 70% and 66% of the variance in adult and adolescent samples respectively. Evidence of relation with other variables was demonstrated with strong correlations between the QSI and measures of depression, hopelessness and borderline symptoms (r = .48 - .68). Conclusions: The results suggest that the QSI may be a reliable and valid method of assessing suicidal ideation in clinical populations.
Antecedentes: Identificar métodos precisos para evaluar ideación suicida es importante. La falta de una definición universal de ideación suicida ha complicado su evaluación. Este estudio describe el desarrollo de un instrumento breve de pensamientos de suicidio. Método: El Cuestionario para Ideación Suicida (CIS) se desarrolló a partir de tres medidas establecidas de ideación suicida. Se eliminaron los ítems de actos o conductas y, para los ítems restantes, se aplicó la definición de ideación suicida de Posner et al. (2007). El cuestionario final tuvo 6 ítems. Se incluyeron adultos (n = 192) y adolescentes (n = 152) de centros de salud mental del servicio de salud pública de Irlanda. Resultados: El CIS demostró una excelente fiabilidad en adultos (α = 0,91) y adolescentes (α = 0,90). En un análisis factorial exploratorio, se identificó una solución de un solo factor que explicó el 70% y el 66% de la varianza en adultos y adolescentes, respectivamente. AAdemás, se demostraron relaciones con otras variables por medio de correlaciones entre el QSI y medidas de depresión, desesperanza y síntomas límite (r = 0,48 - 0,68). Conclusiones: Los resultados sugieren que el QSI puede ser un método fiable y válido para evaluar ideación suicida.
