方法：UCLA PCI的日语版本（1.2版）是在采访患者后通过翻译、回译和完善过程开发的。125例日本局限性前列腺癌患者的信度和效度进行了检查。患者同时回答日文版的兰德36项健康调查问卷（SF-36）和国际勃起功能指数（IIEF）中的5个代表性问题。结果：泌尿和性功能量表的内部一致性信度非常高，而肠功能量表的内部一致性信度较低。排尿功能、性功能量表和排尿困扰量表的重测信度稳定，而肠功能和困扰量表的重测信度相对不稳定。性功能评分与性困扰评分没有高度相关性。此外，性功能差和烦恼与SF-36评分几乎没有关联。泌尿和肠道功能/困扰量表的缺失数据最少（0.8%-2.4%），而性功能和困扰量表的缺失数据相对较高（4.8%-11.2%）。结论：这项初步研究的结果以及之前的美国研究表明，性功能受损如何融入整体生活质量存在种族或文化差异。未来的跨文化比较研究，使用加州大学洛杉矶分校PCI和SF-36将提供有用的信息，文化或种族差异的影响，健康相关的生活质量的前列腺癌患者。
Methods:The Japanese version (version 1.2) of the UCLA PCI was developed through a process of translation, back-translation, and refinement after interviewing patients. Reliability and validity were examined for 125 Japanese patients with localized prostate cancer. The patients simultaneously responded to the Japanese version of the RAND 36-Item Health Survey (SF-36) and five representative questions from the International Index of Erectile Function (IIEF).Results:Internal consistency reliability was very high for both urinary and sexual function scales, and lower for bowel function. The test-retest reliability of the urinary and sexual function scales and the urinary bother scales was stable, while that of the bowel function and bother scales was relatively unstable. Sexual function scores did not correlate highly with sexual bother scores. Furthermore, poor sexual function and bother had little association with the SF-36 scores. Missing data as to urinary and bowel function/bother scales were minimal (0.8%–2.4%), while those for sexual function and bother were relatively high (4.8%–11.2%).Conclusions:The results of this pilot study, together with the previous American study, suggest ethnic or cultural difference in how impaired sexual function is integrated into overall QOL. A future cross-cultural comparative study using the UCLA PCI and SF-36 will provide useful information about the influence of cultural or ethnic differences on health-related QOL in prostate cancer patients.
