Validación de un cuestionario específico de Calidad de Vida con una muestra de pacientes colostomizados o ileostomizados

Abstract

Validation of a stoma-specific quality of life questionnaire in a sample of patients with colostomy or ileostomy. The aim of this study was to assess the validity of a 20-item scale to measure quality of life in a sample of Spanish subjects with colostomy or ileostomy. A cross-sectional multicentresurvey was carried out in the province of Castellon between 2013 and 2014 in fourhospitals with colorectal surgery. The construct validity through confirmatory factor analysis (A.F.C) and structural equation modeling (S.E.M), and internal consistency was determined. A total of 125 patients were recruited for the study; the mean age was 66.72 years, 64% were male, 81.6% had colostomies, 85.6% were diagnosed with intestinal cancer, and 80% were autonomous in stoma care. S.E.M results suggest removing two items for proper fit of the model and two second-order factors, personal and social observed. Cronbach's α for Stoma QoL after S.E.M and for 18 items was 0.861. The study assessed the validity of the 20-item QOL questionnaire in a sample of 125 patients with colostomy or ileostomy. The scale is a valid research tool for stomata, but the number of items could be reduced.
