Objectives:
To present the challenges and adaptations done to the EuroQol Valuation Technology (EQ-VT) protocol to fit the Egyptian culture during the extensive pilot phase of the Egyptian EuroQol 5 Dimension five level (EQ-5D-5L) valuation study DESIGN: This study was a cross-sectional, interviewer-administered face-to-face survey of representative Egyptians using the Arabic version of the EuroQol Group Valuation Technology (EQ-VT-2.1) and a country specific questionnaire pertaining to participants' demographics and opinions about health, life and death SETTING: Participants were recruited from workplaces, university campuses, sporting clubs, shopping malls and other public areas from different Egyptian governorates representing all geographical areas of the country.
Participants:
A total of 1378 participants were interviewed from July 2019 to March 2020 by 12 interviewers to select a representative sample in terms of: geographical distribution, age and gender, of which 75 participants did not complete the interview, 298 interviews were pilot and 1005 interviews were real of which 974 interviews were used for the valuation study. Two participants did not complete the country-specific questionnaire but completed the valuation protocol; therefore, 1301 interviews were included in the final analysis of country specific questions.
Results:
Some modifications were applied to the protocol. The 'wheelchair example' was modified to 'migraine example' since most of the participants in the pilot interviews considered being in a wheelchair 'worse than dead'. There was some ambiguity in the Egyptian translated version for the EQ-5D-5L between levels 4 and 5 of the pain and depression dimensions. This was overcome by using colour coding to express the different levels of severity. A pictorial representation for the EQ-5D-5L health states was used to interview illiterate and less educated participants.
Conclusion:
In the Egyptian valuation study, the modifications made to the EQ-VT protocol made it feasible and culturally acceptable to the Egyptian participants.
