IBS-QOL专用量表在肠易激综合征患者中的运用

Evaluation of IBS-QOL Scale in Irritable Bowel Syndrome

目的 评价Patrick等编制的IBS QOL专用量表在中国肠易激综合征 (irritablebowelsyn drome ,IBS)患者中的信度和效度。方法 通过自填方式调查消化科门诊 12 3例IBS患者。信度采用折半信度及内部一致性分析 ,效度采用维度相关分析及结构效度分析。结果 本研究中量表折半信度γ =0 86 ,内部一致性除躯体意念、挑食外 ,其余各领域的克朗巴赫系数α在 0 71～ 0 89之间 ;维度相关性分析 ,除行为障碍外 ,其他各维度中相关系数基本在 0 6 0以上 ,各纬度中的条目得分与其它维度无关。因子分析 ,在载荷系数 0 5的水准上选出 8个主成分 ,与理论结构基本一致 ,结构效度累计贡献率达 72 7%。结论 IBS QOL专用量表有较好的效度及信度 ,可试用于国人IBS患者生命质量的测评。

Objective To evaluate the reliability and validity of IBS-QOL scale in irritable bowel syndrome (IBS) patients. Methods IBS-QOL scale was applied to survey the quality of life of 123 IBS patients. The split-half and internal consistency method were used to evaluate the reliability, and with the construct method to evaluate the validity. Results The split-half reliability was 0.86. Cronbach's α-coefficient of all domains was between 0.71 and 0.89 except body image and food avoidance; In the correlation analysis, the correlations between items and its subscale structure were above 0.60 (except interference with activity), but there were no correlations between items and other subscale structure. Eight components from factorial analysis were in accordance with theoretical structure.The cumulative contribution rate was 72.7%. Conclusions The reliability and validity of IBS-QOL scale are acceptable. It might be useful for us to assess the QOL of IBS patients in China.
