Este estudio trata la reevaluacion de la confiabilidad y validez del Inventario de Actitudes frente al Dolor Cronico-version breve, (IAD-breve) con 183 pacientes con dolor cronico no oncologico. El IAD-breve 28 items evalua las creencias en el dolor cronico relacionadas al control, emocion, solicitud, cura medica, dano fisico, incapacidad y medicacion. El analisis resulto en siete dominios y 28 items. Hubo diferencias en la ubicacion de dos items y, despues de analisis, se decidio removerlos. Cuatro dominios presentaron valores de alfa de Cronbach considerados buenos (entre 0,74 y 0,85) y en tres, moderados (entre 0,58 y 0,65). El IAD-breve 28 items en lengua portuguesa es superior a la primera version.
