SummaryObjective: This study aims to investigate the validity and reliability of the Turkish Revised American Pain Society Patient Outcome Questionnaire (APS-POQ-R-TR). Methods: A methodological and cross-sectional design was used. This study included a total of 250 surgical patients (98 males, 152 females) between January 2015 and January 2016. Data were collected using a demographic questionnaire and the APS-POQ-R. Language equivalence, content and construct validity, and reliability of the scale were evaluated. Results: The Pearson correlation coefficient of the scale for parallel test reliability was 0.362, and the Cronbach's alpha value was determined as 0.88 in the APS-POQ-R-TR. According to fit indexes of the confirmatory factor analysis [x2/SD=362.53/125=2.90; RMSEA=0.087 (90% CI: 0.077-0.098); CFI=0.95; IFI=0.95; NNFI=0.94], three factors were found to be appropriate for the APS-POQ-R-TR.
Conclusion:The adaptation of the translated APS-POQ-R in Turkey is reliable and valid to measure and evaluate the quality of postoperative pain management in the Turkish population.
