Aim The aim of this study was to determine how socio‐demographic and clinical variables affect quality of life ( Q o L ) and to assess the validity of a 20‐item scale in a sample of I talian subjects with colostomy, ileostomy and multiple stomata. Method A cross‐sectional multicentre survey was carried out in I taly between 2009 and 2010 in 73 stoma centres coordinated by the U niversity of P adova. Patients aged 18 years old and above with a history of nontemporary stoma were included in the study. The S toma C are Q o L scale was measured and validated using a R asch model. Socio‐demographic and clinical characteristics were considered in the analyses. Results Two hundred and fifty‐one patients were recruited for the study; the mean age was 62 years, 58% were men, 72% had colostomy and 25% ileostomy; approximately 70% of patients had intestinal cancer requiring a stoma, 13% a complication and 10% an inflammatory disease. No significant differences were observed throughout strata in the S toma Care Q o L scale index, except for geographical area, where subjects from south Italy showed a significantly lower index than subjects living in other parts of Italy ( P < 0.01). Colostomy and ileostomy patients reported very similar Q o L . Cronbach's alpha for the S toma Care Q o L scale was 0.90 (95% CI 0.88–0.92). Rasch analysis supported the viability of the S toma Care Q o L scale questionnaire and showed acceptable goodness‐of‐fit. Three under‐fitted items were observed. Conclusion The study confirms the validity of the 20‐item S toma C are Q o L scale questionnaire as a research tool for stoma patients but the number of items could be reduced.
