The aim of this study was to determine how socio-demographic and clinical variables affect quality of life (QoL) and to assess the validity of a 20-item scale in a sample of Italian subjects with colostomy, ileostomy and multiple stomata.
A cross-sectional multicentre survey was carried out in Italy between 2009 and 2010 in 73 stoma centres coordinated by the University of Padova. Patients aged 18 years old and above with a history of nontemporary stoma were included in the study. The Stoma Care QoL scale was measured and validated using a Rasch model. Socio-demographic and clinical characteristics were considered in the analyses.
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 Stoma Care QoL 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 QoL. Cronbach's alpha for the Stoma Care QoL scale was 0.90 (95% CI 0.88-0.92). Rasch analysis supported the viability of the Stoma Care QoL scale questionnaire and showed acceptable goodness-of-fit. Three under-fitted items were observed.
The study confirms the validity of the 20-item Stoma Care QoL scale questionnaire as a research tool for stoma patients but the number of items could be reduced.
本研究旨在确定社会人口统计学和临床变量如何影响生活质量（QoL），并评估一种 20 项量表在意大利结肠造口、回肠造口和多个造口患者样本中的有效性。
2009 年至 2010 年，在帕多瓦大学协调的 73 个造口中心的意大利进行了一项横断面多中心调查。纳入研究的患者为有非临时性造口史、年龄在 18 岁及以上的患者。使用 Rasch 模型测量和验证造口护理生活质量量表。分析中考虑了社会人口统计学和临床特征。
研究共纳入 251 名患者；平均年龄为 62 岁，58%为男性，72%为结肠造口，25%为回肠造口；约 70%的患者因肠道癌症需要造口，13%的患者因并发症需要造口，10%的患者因炎症性疾病需要造口。除地理区域外，造口护理生活质量量表指数在各层之间无显著差异，意大利南部地区的患者指数明显低于其他地区的患者（P < 0.01）。结肠造口和回肠造口患者报告的生活质量非常相似。造口护理生活质量量表的 Cronbach's alpha 为 0.90（95%置信区间 0.88-0.92）。Rasch 分析支持造口护理生活质量量表问卷的可行性，并显示出可接受的拟合优度。观察到 3 个拟合不足的项目。
本研究证实了 20 项造口护理生活质量量表问卷作为研究工具的有效性，但项目数量可以减少。
