The Barriers Questionnaire II (BQ-II) was developed to assess barriers to effective pain management. In this study, we aimed to assess the reliability and validity of the newly developed Japanese version of the BQ-II (JBQ-II).
This study used a cross-sectional design. The study was conducted an ambulatory infusion center for cancer in a general hospital in Tokyo, Japan. Participants were 120 Japanese patients with cancer and 21 Japanese health professionals with experience in pain management. Cronbach's alpha coefficient was used to calculate reliability. Test-retest reliability was assessed with Spearman's intra-class correlation coefficient (ICC). Construct, criterion-related, and discriminant validity were assessed using information about pain management, daily life, mental health, and subjective health.
The Cronbach's alpha was 0.90 for the JBQ-II, and all ICCs exceeded 0.70 (P < 0.01). Factor analysis showed the JBQ-II had a virtually identical structure to the BQ-II, and path analysis supported the JBQ-II constructs. The JBQ-II was weakly correlated with poor mental state (r = 0.36, P < 0.01). Patients' JBQ-II scores were significantly higher than health professionals' scores.
The JBQ-II is a valid and reliable measure of patient-related barriers to pain management among Japanese adult patients with cancer.
障碍问卷 II（BQ-II）是为评估有效疼痛管理障碍而开发的。本研究旨在评估新开发的日本版 BQ-II（JBQ-II）的可靠性和有效性。
本研究采用横断面设计。研究在日本东京的一家综合医院的门诊输液中心进行。参与者包括 120 名日本癌症患者和 21 名具有疼痛管理经验的日本卫生专业人员。使用克朗巴赫α系数评估可靠性。使用 Spearman 组内相关系数（ICC）评估重测信度。使用有关疼痛管理、日常生活、心理健康和主观健康的信息评估结构、效标关联和判别有效性。
JBQ-II 的克朗巴赫α系数为 0.90，所有 ICC 均超过 0.70（P<0.01）。因子分析显示，JBQ-II 与 BQ-II 的结构几乎相同，路径分析支持 JBQ-II 的结构。JBQ-II 与较差的精神状态呈弱相关（r=0.36，P<0.01）。患者的 JBQ-II 评分明显高于卫生专业人员的评分。
JBQ-II 是一种有效且可靠的工具，可用于评估日本成年癌症患者疼痛管理的患者相关障碍。
