Long-term pain is an important outcome after inguinal hernia repair. The aim of this study was to test the validity and reliability of a specific Inguinal Pain Questionnaire (IPQ).
The study recruited patients aged between 15 and 85 years who had undergone primary inguinal or femoral hernia repair. To test the validity of the questionnaire, 100 patients received the IPQ and the Brief Pain Inventory (BPI) 1 and 4 weeks after surgery (group 1). To test reliability and internal consistency, 100 patients received the IPQ on two occasions 1 month apart, 3 years after surgery (group 2). Non-surgery-related pain was analysed in group 3 (2853 patients).
A significant decrease in IPQ-rated pain intensity was observed in the first 4 weeks after surgery (P < 0.001). Significant correlations with corresponding BPI pain intensity items corroborated the criterion validity (P < 0.050). Logical incoherence did not exceed 5.5 per cent for any item. Values for kappa in the test-retest in group 2 were higher than 0.5 for all but three items. Cronbach's alpha was 0.83 for questions on pain intensity and 0.74 for interference with daily activities.
This study found good validity and reliability for the IPQ, making it a useful instrument for assessing pain following groin hernia repair.
长期疼痛是腹股沟疝修补术后的一项重要结果。本研究旨在检验特定腹股沟疼痛问卷（IPQ）的有效性和可靠性。
该研究招募了年龄在15至85岁之间、接受过原发性腹股沟疝或股疝修补术的患者。为检验问卷的有效性，100例患者在术后1周和4周接受IPQ及简明疼痛量表（BPI）（第1组）。为检验可靠性和内部一致性，100例患者在术后3年，相隔1个月接受两次IPQ（第2组）。在第3组（2853例患者）中分析了与手术无关的疼痛。
术后前4周观察到IPQ评定的疼痛强度显著降低（P<0.001）。与相应BPI疼痛强度项目的显著相关性证实了效标效度（P<0.050）。任何项目的逻辑不连贯均未超过5.5%。第2组重测的kappa值除3项外均高于0.5。疼痛强度问题的Cronbach's α为0.83，日常活动干扰问题的Cronbach's α为0.74。
本研究发现IPQ具有良好的有效性和可靠性，使其成为评估腹股沟疝修补术后疼痛的有用工具。
