Propiedades psicométricas del inventario de ideación suicida positiva y negativa PANSI

Abstract

Suicide behavior as a mental health problem requires a good management with improved assessment tools, particularly for suicide ideation. An instrumental study was carried out to establish the psychometric properties of the Positive and Negative Suicide Ideation Inventory (PANSI) in 1318 students, 13 to 19 years-old, from three cities in Colombia, with ages from, and from attending 8th to 11th secondary school levelsgrade in three cities in Colombia. The expected theoretical structure was obtained by exploratory and confirmatory factorial analysis. Also, a favorable fit was found, according to the Rasch model (except item 4). Moreover, when internal consistencies were analyzed, a value of ? = .77 was obtained for positive suicide ideation, while ? = .89 was shown for negative suicide ideation. These data indicate that PANSI presents construct validity and consistency, according to the purpose and context in which it was elaborated. Therefore, we suggest the use of a 13 items PANSI in high school students able to identify the two dimensions of suicidal ideation.
