Psychometric properties of a brief Spanish version of Stigmatizing Situations Inventory / Propiedades psicométricas de una versión breve en español del Inventario de Situaciones Estigmatizantes

Abstract

Abstract Overweight and obese people are a frequent target of weight stigma. However, there are no Spanish-Language validated inventories measuring weight stigma situations. Therefore, we sought to validate a brief Spanish version of the Stigmatizing Situations Inventory (SSI) in a sample of Chilean adults. A psychometric study with 377 Chilean adults was designed (Mage = 45.0, SD = 8.7; 62% female). Twenty-four items available from two previous versions of the SSI developed were back-translated from English to Spanish, and semantically adapted to the Chilean sample. We explored the factorial structure with 173 participants, and then confirmed it with 204 subjects. We obtained evidence of concurrent validity with other psychological measures, as well as evidence of reliability. Our results identified a single factor structure grouping 10-items, with factorial loadings greater than .60. The overall fit indices are excellent. There is evidence of concurrent validity with body mass index (r = .43), anger (r = .19), anxiety (r = .29), and daily life discrimination (r = .26); all with p.60 e indicadores de bondad de ajuste excelentes. La consistencia interna de la escala fue alta (a = .91, ). Además se obtuvo evidencia de la validez concurrente del ISE con otras medidas: índice de masa corporal (r = .43), ira (r = .19), ansiedad (r = .29) y discriminación en la vida diaria (r = .26); todos con p < .05. La versión breve en español del ISE mostró ser válida y confiable. Esta escala puede ser utilizada por investigadores y profesionales de la salud que estudian las consecuencias psicológicas de la obesidad.
