Their app works by allowing you to send items from participating restaurants to a friend.
Activity behavior included three items: exercising, participating in outdoor activities and doing household duties.
Sample items include, "Participating in this study has helped me feel like a person, not just a disease," and "The process of completing this study was worthwhile".
Based on the answers to these 3 items, the participating physicians were categorised as non drinkers (AUDIT-C score 0), drinkers (AUDIT-C score 1 to 3 for women and 1 to 4 for men), and at risk drinkers (AUDIT-C score ≥ 4 for women and ≥ 5 for men).
The field team estimated that nearly half of the community required some form of food aid over the study period, and requested to provide food items to participating households as part of study compensation for the considerable time taken in follow-up visits.
Each WinFS Item has two properties, named IncomingRelationships and OutgoingRelationships, which provides access to the set of relationship instances the item participates in.
To describe a relation, one needs to specify a list of annotations or relations that participate in the relation and roles for how each item participates in the relation.
