目的 探讨 WaLIDD(working ability,location,intensity,days of pain,dysmenorrhea)量表对女大学生痛经的诊断价值并分析痛经的影响因素.方法 采用方便整群抽样,于2023年5-7月抽取广东省619名女大学生作为研究对象,采用WaLIDD量表、简版经前期综合征量表(SPAF)及人口学特征问卷等对研究对象进行调查.结果 WaLIDD量表的Cronbach'sa系数为0.755.采用经期服用止痛药作为效标测量工具,Spearman相关分析结果显示,女大学生 WaLIDD量表得分、各条目得分与经期服用止痛药均呈正相关.受试者工作特征(ROC)曲线分析显示,WaLIDD量表诊断痛经的曲线下面积(AUC)为0.931(95％CI:0.910～0.952),敏感度为0.989,特异度为0.744;WaLIDD量表得分5.5分是区分有无痛经的分界值.二元logistic逐步回归分析结果显示,互联网搜寻月经相关信息、经前期综合征、月经过多均正向预测痛经(OR=1.615、2.236、1.395,P＜0.05),自评健康状况负向预测痛经(OR=0.763,P＜0.05).结论 WaLIDD量表在广东女大学生群体中具有良好信效度,可作为痛经的测评工具.互联网搜寻月经相关信息、自评健康状况、经前期综合征、月经过多是女大学生痛经的主要预测因素.
Diagnostic efficacy of the WaLIDD scale and analysis of influencing factors in dysmenorrhea among female college students
Objective To explore the diagnostic value of the WaLIDD(working ability,location,intensity,days of pain,dysmenorrhea)scale for dysmenorrhea in female college students and analyze the influencing factors of dysmenorrhea.Meth-ods Convenience cluster sampling was used to select 619 female college students in Guangdong Province from May to July 2023 as the research participants.The WaLIDD scale,the Shortened Premenstrual Assessment Form(SPAF),and a demo-graphic characteristics questionnaire were used to investigate the research participants.Results The Cronbach's α coefficient of the WaLIDD scale was 0.755.Using pain relievers during menstruation as the criterion measurement tool,Spearman cor-relation analysis showed that the scores of the WaLIDD scale and each item of female college students were positively corre-lated with the use of pain relievers during menstruation.The receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC)of the WaLIDD scale for diagnosing dysmenorrhea was 0.931(95％CI:0.910-0.952),with a sensitivity of 0.989 and a specificity of 0.744.Moreover,a score of 5.5 on the WaLIDD scale was the cutoff value for distinguishing the presence or absence of dysmenorrhea.Binary logistic stepwise regression analysis indicated that searching the internet for menstrual-related information,premenstrual syndrome,and menorrhagia all positively predicted dysmenorrhea(OR=1.615,2.236,1.395,P＜0.05),while self-rated health status negatively predicted dysmenorrhea(OR=0.763,P＜0.05).Conclusion The WaLIDD scale has good reliability and validity in the female college student pop-ulation in Guangdong and can be used as a tool for evaluating dysmenorrhea.Searching the internet for menstrual-related in-formation,self-rated health status,premenstrual syndrome,and menorrhagia are the main predictive factors for dysmenor-rhea in female college students.
