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.

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.
