Despite recognition that pain management is an important component in the t
reatment of Japanese cancer patients, progress in this area has been slowed
by the lack of an appropriate measure of pain. In a prospective, single-in
stitution study, a Japanese translation of the Brief Pain Inventory (BPI-J)
was administered to 121 patients to assess the intensity and impact of can
cer-related pain. After an analysis of the instrument's reliability and val
idity, this study tested the utility of the new measure in an analysis of t
he adequacy of analgesic prescription. Results were compared with predictiv
e 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 i
ndicate a reliable self-report pain instrument. After comprising these two
subscales indicate a reliable self-report pain instrument. After establishi
ng the validity and reliability of the BPI-J, we examined possible predicto
rs of inadequate pain management in these Japanese cancer patients. Similar
to studies done in other countries, women patients and those whose pain se
verity was underestimated by their physician were more likely to be underma
naged for pain. The results of this study support the utility of the Japane
se BPI for studies of the epidemiology of cancer pain in Japan, as well as
for the assessment of pain treatment outcome Japanese-speaking patients. (C
