Q: What are the eligibility criteria for getting a HKD50 supermarket voucher?
A: Every participant who has completed the baseline questionnaire is entitled to receive a supermarket voucher worth HKD50. Additional supermarket vouchers (each HKD50) would be offered to participants who complete at least 3 monthly updates in every 6 months (months 1-6, months 7-12, months 13-18 and so on).

Q: How many HKD50 supermarket vouchers can I get at most throughout the whole study?
A: [For participants enrolled in 2022] At most, you can get 7 supermarket vouchers worth HKD50 each, amounting to HKD350. ( $50 [completing baseline questionnaire] + $50 x 6 [completing specified number of monthly updates throughout the 24-/36-month study period] = $350 )

[For participants enrolled in 2023] At most, you can get 5 supermarket vouchers worth HKD50 each, amounting to HKD250. ( $50 [completing baseline questionnaire] + $50 x 4 [completing specified number of monthly updates throughout the 24-month study period] = $250 )

Q: How do I know whether I am eligible to receive a supermarket voucher?
A: If you have met the eligibility criteria for getting a supermarket voucher, the system will automatically notify you and ask for your delivery address after you have completed the corresponding monthly update. If the eligibility criteria were not met, the sentence "No redeemable incentives yet" will be displayed on the "Incentive" page. The page also shows the number of monthly updates you have completed every 6 months subsequent to your completion of baseline questionnaire.

A: All data collected in this study will be kept strictly confidential and reported only in aggregate form for publicity and publication in academic journals. They will also be destroyed in no more than 5 years after the completion of study.

Q: Can I invite my friends and family members to join this study?
A: As households are invited based on random sampling and participation is limited to one member within the household only, participants could not invite their own friends or family members to join this study.
