Validation of the Revised American Pain Society- Patient Outcome Questionnaire (APS-POQ-R) for Arabic speaking patients
INTRODUCTION: The American Pain Society-Patient Outcome Questionnaire-Revised (APS-POQ-R) was designed to assess the quality of postoperative pain management in hospitalized patients over 24 hours . It measures 5 domains for pain outcomes; pain severity, interference with function and sleep, adverse effects, perception of pain control, and use of alternative methods for pain control.
OBJECTIVE: To validate the APS-POQ-R Arabic version for the purpose of qaulity improvement, clinical research and clinical practice.
METHODS: The work group that developed the APS-POQ-R encourages its use in local clinical settings. The instrument is translated into 11 languages including Arabic . We piloted tested the survey in 25 Arabic fluent patients before proceeding with a validation study. The Arabic APS-POQ-R was then completed by 200 Egyptian patients at Aswan University Hospital, Aswan, Egypt, 24 hours after surgery. Internal consistency reliability (Cronbach’s alpha) was measured, and group comparisons and correlations conducted.
RESULTS: Two-hundred patients (males n=79, 40%) completed the survey instrument. Means and standard deviations (STD) for age and BMI were (43±17) and (28±4), respectively. Worst pain over 24 hours was significantly higher (P<0.01) for orthopedic surgery (n=49, 24%) compared to general abdominal, urologic and gynecologic surgery (n=128). Patient satisfaction was positively correlated with perception of pain relief, r=0.634, P<0.001 (figure 1A), and negatively correlated with the percentage of time in severe pain, r=-0.602, P<0.001 (figure 1B). Acceptable reliability was demonstrated (Cronbach alpha = 0.78).
CONCLUSION: The Arabic APS-POQ=R version was found to be reliable and valid in detected significant differences in the sample. These findings extend the research on the APS-POQ-R in culturally diverse populations.
