摘要：Se diseñó el Inventario de Desesperanza e Ideación Suicida "IDIS" para identificar Ideación Suicida (IS) y Desesperanza (DS). El estudio fue cuantitativo, no experimental instrumental. Participaron 339 personas (67.6% mujeres y 31.6% hombres), entre estudiantes (54.6%) y empleados (34.8%), el 50.4% pertenecía a estrato medio-bajo. Los instrumentos aplicados fueron el IDIS, BDI-II, PANSI y BHS. Los re sultados obtenidos indicaron favorable armonía interjueces y validez convergente en ambas escalas. En IS se obtuvo una consistencia interna α = .77 con tres factores que explican el 57.87% de la varianza. En la escala DS se obtuvo un α = .86 con dos factores que explican el 57.32% de la varianza. Desde la TRI los ajustes en INFIT y OUTFIT quedaron en el rango esperado. Se concluye que el IDIS puede ser usado como medida confiable y válida, aunque se sugiere revisiones posteriores con la escala IS y estudios de sensibilidad y especificidad.
其他摘要：The objective was to design the Hopeless and Suicide Ideation Inventory, also know as IDIS - Sp anish acronym for inventario de Desesperanza e ¡deación Suicida - and to analyze its psychometric properties. A quantitative empirical research was conducted employing a non-experimental design, an instrumental variable and cross-sectional analysis. Ihree hundred and thirty-nine people participated in the study (67.6% females, 31.6% males), in which 54.6% were students and 34.8' % were employees. Participants completed the IDIS, the Beck Depression Inventory (BDI-II), the Po sitive and Negative Suicide Ideation Inventory, and the Beck Hopelessness Scale. The results indicated an inter-rater reliability and a positive convergent validity in both scales. Suicidal ideation revealed an internal consistency of α = .76, and α = .81 for hopelessness; a total variance of 41 .77% and 47.52% was obtained correspondingly. Based on the Item Response Theory (IRT), the adjustments for INFIT and OUTFIT fell under the expected range. It was concluded that the IDIS is a reli able and valid measure, however, further evaluations on sensitivity and specificity are encouraged.
