RESUMEN

Las personas con sobrepeso u obesidad enfrentan frecuentemente situaciones de estigmatización por el peso; sin embargo, no existen instrumentos validados en español que midan este constructo. En consecuencia, el objetivo de este estudio fue examinar las propiedades psicométricas una versión breve del Inventario de Situaciones Estigmatizantes (ISE) en población chilena. Participaron 377 adultos (Medad = 45.0, DE = 8.7; 62% mujeres). Veinticuatro ítems disponibles en versiones previas del ISE fueron retrotraducidos del inglés al español y adaptados semánticamente. La estructura factorial fue explorada con los registros de 173 de los participantes, y posteriormente confirmada con los 204 restantes. Fue identificada una estructura uni-factorial, con cargas factoriales › .60 e indicadores de bondad de ajuste excelentes. La consistencia interna del inventario fue alta (α = .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.
