评估盆腔器官脱垂症状评分（POP-SS）的内部一致性、结构效度和对变化的敏感性。分析来自三项脱垂研究的数据，包括完成POP-SS的有症状和无症状女性。(1)新西兰的一个社区，（2）苏格兰的两个妇科门诊部和（3）苏格兰的一个妇科手术部。(1)参与者来自12年随访的产后女性调查，被邀请填写脱垂问卷并进行脱垂评估，（2）出现脱垂症状的新妇科门诊患者，随机接受盆底肌肉训练（PFMT）或对照组，（3）接受前部和/或后部脱垂手术的女性，随机接受补片插入或无补片。分析数据以评估内部一致性，结构效度和对POP-SS变化的敏感性。Cronbach’s α、研究间POP-SS评分差异的显著性和干预前后POP-SS评分差异的显著性。内部一致性的Cronbach’s α范围为0.723 - 0.828。接受手术的女性POP-SS评分高于接受保守治疗的女性（平均差异5.0，95% CI 3.1-6.9），后者的评分又高于无症状女性（平均差异5.9，95% CI 4.4-7.4）。POP-SS评分在手术和PFMT后检测到显著差异。手术后的改善显著大于PFMT（z =-3.006，P = 0.003）。POP-SS具有良好的内部一致性和结构效度，对变化敏感。
To assess the internal consistency, construct validity and sensitivity to change of a pelvic organ prolapse symptom score (POP-SS).Analysis of data from three prolapse studies, including symptomatic and asymptomatic women who completed the POP-SS.(1) A community setting in New Zealand, (2) two gynaecology outpatient departments in Scotland and (3) a gynaecological surgery department in Scotland.(1) Participants from a survey of postnatal women at 12-year follow up, invited to complete a prolapse questionnaire and have prolapse assessment, (2) new gynaecology outpatients presenting with prolapse symptoms, randomised to pelvic floor muscle training (PFMT) or control and (3) women having anterior and/or posterior prolapse surgery, randomised to mesh insert or no mesh.Data were analysed to assess internal consistency, construct validity and sensitivity to change of the POP-SS.Cronbach's alpha, significance of differences in POP-SS scores between studies and significance of difference in POP-SS scores pre- to post-intervention.For internal consistency, Cronbach's alpha ranged from 0.723 to 0.828. Women having surgery had higher POP-SS scores than those having conservative management (mean difference 5.0, 95% CI 3.1-6.9), who in turn had higher scores than the asymptomatic women (mean difference 5.9, 95% CI 4.4-7.4). Significant differences in POP-SS score were detected after surgery and PFMT. The improvement due to surgery was significantly greater than that associated with PFMT (z = -3.006, P = 0.003).The POP-SS has good internal consistency and construct validity and is sensitive to change.
