Reliability and validity of the Chinese version of STRATIFY in geriatric inpatients / 中国实用护理杂志

ABSTRACT

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.
