A quantitative empirical research was conducted employing a non-experimental design, an instrumental variable and cross-sectional analysis. Three 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.

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 reliable and valid measure, however, further evaluations on sensitivity and specificity are encouraged. http://revistas.usb.edu.co/index.php/IJPR/article/view/2100/1877SuicideSuicidal ideationHopelessnessPsychometricClassical test theoryItem response theory |
