The Positive and Negative Suicide Ideation Inventory: Development and Validation

Abstract

We conducted two studies to develop and validate a brief self-report measure for assessing the frequency of positive and negative thoughts related to suicidal behavior. Items on this new measure, the Positive and Negative Suicide Ideation inventory, were generated by undergraduates. In Study 1, we administered a 20-item version of the inventory to 150 male and 300 female undergraduates and conducted an exploratory principal axis factor analysis with varimax rotation. Two factors, Positive Ideation and Negative Ideation, were retained. In Study 2, we conducted a confirmatory factor analysis to validate the fit of the one-factor and the oblique two-factor models to data from another sample of 84 men and 202 women. The oblique two-factor model provided an excellent fit to the sample data. We also examined preliminary evidence of concurrent and predictive validity. Over-all, these findings suggested that the inventory is a well-developed self-report measure for assessing the frequency of positive and negative thoughts related to suicidal behavior.

Development and initial psychometric properties of the University of Texas at San Antonio Future Disposition Inventory

“…Approximately 222 (85.4%) were single, never married. In addition to the new inventory, all study participants completed the 14‐item Positive and Negative Suicide Ideation (PANSI; Osman, Gutierrez, Kopper, Barrios, & Chiros, 1998) inventory. The PANSI is used widely to assess thoughts and feelings about suicide (see, e.g., Gutierrez & Osman, 2008; Muehlenkamp, Gutierrez, Osman, & Barrios, 2005; Osman et al, 2003).…”

Gender Differences in Risk and Protective Factors for Suicidal Ideation Among College Students

“…Estimates of internal consistency and concurrent validity of the total RFL-YA and the five subscales are satisfactory (see Gutierrez et al, 2000;Osman, 1999). Scores on the RFL-YA have been shown to be correlated with the Suicide Probability Scale (SPS; Cull & Gill, 1992) and the Positive and Negative Affect Schedule (PANAS; Osman, Gutierrez, Kopper, Barrios, & Chiros, 1998) in young adults (Gutierrez et al, 2002). The scale had good reliability and predictive validity, distinguishing suicidal ideators from suicide attempters.…”

Factores de riesgo de la ideación suicida en adolescentes de media vocacional de dos Instituciones Educativas de la localidad de Fontibón. Un análisis desde la Psicología Forense

“…A partir de lo presentado anteriormente, donde se observa la importancia del estudio científico de la conducta suicida, teniendo en cuenta los factores precipitantes que lo conducen, Osman et al (1998), diseñaron un cuestionario que contiene 14 ítems, el cual mide la frecuencia con que se presenta la ideación suicida en los adolescentes y adultos, incorporando pensamientos positivos y negativos de riesgo. Este inventario positivo y negativo de Ideación Suicida (PANSI), se divide en dos sub-escalas: positivos ideación (PANSI-PI; seis puntos) y la ideación suicida negativo (PANSI-NSI; ocho ítems).…”

“…Algunas de las investigaciones realizadas fueron las desarrolladas por Osman et al (1998); Villalobos y Galvis (2010); Chang, Lin y Chou (2009).…”
