Despite recognition that pain management is an important component in the treatment of Japanese cancer patients, progress in this area has been slowed by the lack of an appropriate measure of pain. In a prospective, single-institution study, a Japanese translation of the Brief Pain Inventory (BPI-J) was administered to 121 patients to assess the intensity and impact of cancer-related pain. After an analysis of the instrument's reliability and validity, this study tested the utility of the new measure in an analysis of the adequacy of analgesic prescription. Results were compared with predictive models from studies using non-Japanese patient groups. Factor analysis of the BPI items resulted in two factors, pain severity and pain interference, showing consistency with other language versions of the tool. Coefficient alphas of greater than 0.80 for the items comprising these two subscales indicate a reliable self-report pain instrument. After establishing the validity and reliability of the BPI-J, we examined possible predictors of inadequate pain management in these Japanese cancer patients. Similar to studies done in other countries, women patients and those whose pain severity was underestimated by their physician were more likely to be undermanaged for pain. The results of this study support the utility of the Japanese BPI for studies of the epidemiology of cancer pain in Japan, as well as for the assessment of pain treatment outcome in Japanese-speaking patients.
尽管人们认识到疼痛管理是日本癌症患者治疗中的一个重要组成部分，但由于缺乏合适的疼痛测量方法，该领域的进展一直较为缓慢。在一项前瞻性的单机构研究中，对121名患者进行了《简明疼痛问卷》日语版（BPI-J）的测试，以评估癌症相关疼痛的强度和影响。在分析了该工具的信度和效度后，本研究在分析镇痛处方的充分性时测试了这一新测量方法的效用。将结果与使用非日本患者群体的研究中的预测模型进行了比较。对BPI项目的因子分析产生了两个因子，即疼痛严重程度和疼痛干扰，这与该工具的其他语言版本一致。构成这两个子量表的项目的系数阿尔法大于0.80，表明这是一个可靠的自我报告疼痛工具。在确立了BPI-J的效度和信度后，我们研究了这些日本癌症患者疼痛管理不足的可能预测因素。与其他国家的研究类似，女性患者以及那些疼痛严重程度被医生低估的患者更有可能在疼痛管理方面不足。本研究结果支持日语版BPI在日本癌症疼痛流行病学研究以及对讲日语患者的疼痛治疗结果评估中的效用。
