Abstract

BACKGROUND: We aimed to develop and validate a Portuguese version of the Obstetric Quality of Recovery-10 (ObsQoR-10-Portuguese) patient-reported outcome measure and evaluate its psychometric properties.METHODS: After ethical approval, we recruited term pregnant women undergoing uncomplicated elective cesarean delivery in a single Brazilian institution. Women were invited to complete the translated ObsQoR-10-Portuguese and EuroQoL (EQ-5D) questionnaires (including a global health visual analog scale [GHVAS]) at 24hours (±6hours) following delivery, and a subset of women an hour later. We assessed validity and reliability of ObsQoR-10-Portuguese.RESULTS: One hundred thirteen and 29 enrolled women completed the surveys at 24h and 25h (100% response rate).VALIDITY: (i) Convergent validity: ObsQoR-10-Portuguese correlated moderately with EuroQoL score (r=-0.587) and GHVAS score (r=0.568) at 24h. (ii) Discriminant validity: ObsQoR-10 discriminated well between good versus poor recovery (GHVAS score = 70 versus < 70; difference in mean scores 14.2; p<0.001). (iii) Hypothesis testing: 24-h ObsQoR-10-Portuguese scores correlated with gestational age (r=0.191; p=0.043). (iv) Cross-cultural validity: Differential item functioning analysis suggested bias in 2 items. Reliability: (i) Internal consistency was good (Cronbach's alpha=0.82 and inter-item correlation=0.31). (ii) Split-half reliability was very good (Spearman-Brown Prophesy Reliability Estimate=0.80). (iii) Test re-test reliability was excellent (intra-class correlation coefficient=0.87). (iv) Floor and ceiling effects: <5% women scored either 0 or 100 (lowest and highest scores, respectively).CONCLUSION: ObsQoR-10-Portuguese is valid and reliable, and should be considered for use in Portuguese-speaking women to assess their quality of inpatient recovery following cesarean delivery.
