Our objective was to develop a self-report quality of life measure specific to urinary incontinence (I-QOL) that could be used as an outcome measure in clinical trials and in patient care centers.
The I-QOL was developed from interviews of 20 individuals with urinary incontinence. Refining the questionnaire was accomplished by structured interviews of 17 individuals with urinary incontinence. Testing the I-QOL's psychometric properties involved two administrations (n = 62) along with measures of psychologic well-being and functional status.
The rigorous development process ensured that the measure was complete and understandable. The I-QOL proved to be internally consistent (alpha 0.95) and highly reproducible (r = 0.93; 18 days; SD 4). For discriminant validity, severity of incontinence (P < 0.0001) and number of medical appointments in the past year to treat incontinence (P < 0.0001) significantly predicted I-QOL scores. Convergent validity analyses confirmed our predictions that the I-QOL scores were more closely related to overall well-being than bodily pain.
The I-QOL proved to be valid and reproducible as a self-administered measure for assessing quality of life of patients with urinary incontinence.
我们的目标是开发一种专门针对尿失禁的生活质量自我报告测量工具（I-QOL），可用于临床试验和患者护理中心作为结局指标。
I-QOL是通过对20名尿失禁患者进行访谈而开发的。通过对17名尿失禁患者进行结构化访谈来完善问卷。对I-QOL的心理测量学特性进行测试涉及两次施测（n = 62）以及心理幸福感和功能状态测量。
严格的开发过程确保了该测量工具完整且易于理解。I-QOL被证明具有内部一致性（α = 0.95）且高度可重复（r = 0.93；间隔18天；标准差4）。对于判别效度，尿失禁严重程度（P < 0.0001）和过去一年中治疗尿失禁的医疗预约次数（P < 0.0001）显著预测I-QOL得分。收敛效度分析证实了我们的预测，即I-QOL得分与总体幸福感的相关性比与身体疼痛的相关性更紧密。
I-QOL被证明是一种有效且可重复的自我施测测量工具，用于评估尿失禁患者的生活质量。
