Summary This study investigated the cross-cultural factor stability and internal consistency of the Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R); a measure of the quality of postoperative pain management employed internationally. We conducted exploratory factor analysis (EFA) of APS-POQ-R data from two point-prevalence studies comprising 268 and 311 surveys of Danish and Australian medical-surgical patients. Parallel analysis indicated four and three factor solutions for Danish and Australian patients respectively, which accounted for 58.1% and 52.9% of variance. Internal consistency was unsatisfactory among both Danish (Cronbach α=.54) and Australian (Cronbach α=.63) cohorts. There was a high degree of between-group similarity in item-factor loadings of variables coded as "pain experience", but not "pain management". This reflected cross-cultural differences in ratings of treatment satisfaction. For Danish patients, satisfaction was associated with the degree of pain severity and activity interference whereas for Australian patients, satisfaction was associated with their perceived ability to participate in treatment. To facilitate further cross-cultural comparison, we compared our findings to past research conducted in the U.S. and Iceland. EFA supported the construct validity of the APS-POQ-R as a measure of "pain experience", but indicated that items measuring "pain management" may vary cross-culturally. Findings highlighted the need for further validation of the APS-POQ-R internationally. PERSPECTIVE: This study revealed the APS-POQ-R as a valid measure of postoperative pain experience for Danish and Australian patients. Measures of patients' perception of pain management were not robust to group differences in treatment expectations and demonstrated cross-cultural instability. Results highlighted difficulties in establishing stable cross-cultural, cross-population subscales for the APS-POQ-R.
