膀胱过度活动症症状评分表对中国OAB患者结果评估的重复信度及与其他症状评分工具间相关性的研究

目的 评估中文版膀胱过度活动症(OAB)症状评分表(OABSS)对中国OAB患者症状评估的重复信度及与其他评分工具间的相关性. 方法 50例OAB患者分别于第0天和第(14±2)天填写2次OABSS、患者感知膀胱症状情况分级量表(PPBC)、国际前列腺症状评分表(IPSS)及3 d排尿日志卡.采用内部相关系数(ICC)评价基线(0 d)和2周后OABSS问卷表总评分间的相关程度,采用加权Kappa系数评估OABSS各问题评分间的相关程度,采用Cronbach's α系数计算OABSS的内部信度;分别计算基线和2周后OABSS问卷表总评分与3 d排尿日志卡中临床变量、IPSS总评分、IPSS QOL评分及PPBC评分之间的Pearson或Spearman相关系数. 结果 OABSS总评分的ICC为0.9172,各项评分的加权Kappa系数为0.5902～0.9274,基线与2周后OABSS的Cronbach's α系数分别为0.3069和0.3285;OABSS与排尿日志卡上的临床变量间(日平均排尿次数除外)Pearson相关系数为0.2643～0.6900;与IPSS总评分的 Pearson相关系数为0.4734和0.4929,Spearman相关系数为0.4133和0.4149;与PPBC的Spearman相关系数为0.4083和0.4127.结论中文版OABSS对中国OAB患者结果评估的重复信度较好,与排尿日志卡上的临床变量、IPSS总评分以及PPBC之间的相关程度较高.

Test-retest reliability of the Overactive Bladder Symptom Score and its correlation with other overactive bladder symptom evaluation tools among Chinese overactive bladder symptom patients

Objective To assess the test-retest reliability of the Chinese version of Overactive Bladder Symptom Score (OABSS) and its correlation with other overactive bladder symptom (OAB)evaluation tools among Chinese OAB patients. Methods Fifty OAB patients completed the OABSS,PPBC, IPSS forms and a three-day voiding diary card for twice in day 0 and day 14±2, respectively.Test-retest reliability was examined using internal correlation coefficient (ICC) and weighted Kappa coefficients between first and second application of OABSS. The internal reliability was evaluated using Cronbach's α coefficient method. Pearson or/and Spearman correlation coefficients were calculated for testing the correlation between OABSS and IPSS, IPSS QOL, PPBC as well as clinical variables in the three-day voiding diary cards. Results ICC of OABSS total score was 0.9172, weighted Kap-pa coefficients of individual scores in OABSS were 0.5902-0.9274;Cronbach's α coefficients were 0. 3069 and 0. 3285, respectively. In the first and second application of OABSS, the Pearson correlation coefficients were 0. 2643-0. 6900 between OABSS and clinical variables in the three-day voiding diary card (except for average daily frequency of urination);the Pearson correlation coefficients were 0. 4734 and 0. 4929, and the Spearman correlation coefficients were 0. 4133 and 0. 4149 between OABSS and IPSS total score;the Spearman correlation coefficients were 0.4083 and 0.4127 between OABSS and PPBC. Conclusions The Chinese version of OABSS manifest test-retest reliability among Chinese OAB patients. It has also a high correlation with IPSS total score, PPBC and clinical variables in the three-day voiding diary cards.
