摘要
目的 检验中文版托马斯跌倒风险评估工具(St Thomas's Risk Assessment Tool in Falling Elderly Inpatients,STRATIFY)的信度和效度.方法 翻译STRATIFY,使用中文版STRATIFY对404例住院老年患者进行调查,评价中文版量表的信效度.结果 量表的评定者间信度为0.951,重测信度0.885,内部一致性信度(Cronbachα)为0.523.各条目与总分相关系数>0.3.区分效度方面有跌倒史组和无跌倒史组STRATIFY总分比较差异有统计学意义.预测能力尚可,建议最佳临界值为2分,此时灵敏度与特异度相对平衡,为64.3%与78.2%.结论 中文版STRATIFY应用于我国住院老年患者具有良好的评定者间信度、重测信度、区分效度以及预测效度,可作为老年住院患者跌倒风险的初步筛选工具.此外,由于量表的内部一致性较低,建议对量表的条目进行修订,以提供更为准确的跌倒预测工具.
Objective To test the reliability and validity of the Chinese version STRATIFY (St Thomas Risk Assessment Tool in Falling Elderly Inpatients) for geriatric inpatients.Methods The scale was translated and 404 geriatric inpatients were evaluated by the Chinese version STRATIFY and evaluate its reliability and validity.Results Chinese version STRATIFY was found with good feasibility.The Pearson correlation coefficient of reliability between testers was 0.951,the retest reliability was 0.885,internal consistency reliability (Cronbach's αt) was 0.523.The values of item-total correlation was over 0.3.The distinguish validity in difference of STRATIFY scores between groups with/without fall history was statistically significant.Predictive validity was moderate,the best cut-off point was determined at 2 points,and sensitivity and specificity were respectively 64.3% and 78.2%.Conclusions Chinese version STRATIFY applied in Chinese geriatric inpatients showed good reliability between testers,retest reliability,distinguish validity and predictive validity,and it could be used to assess the fall risk of Chinese geriatric inpatients.In addition,as the internal consistency was lower,we can revise the entry of STRATIFY to provide a more accurate predicting tool.
