Which behavioral evaluations would be most useful for evaluating the healing project campaign?

Recently, Vaseline’s management and marketing teams devised a new program. The Vaseline Healing Project was created to place Vaseline and small first aid kits into the hands of people in less-developed countries. One advertisement notes that most people only think of Vaseline when they have chapped lips or some other small malady, but that in some parts of the world a skin problem can result in far more serious health issues.26 The program is relatively straightforward. The purchase of one container of Vaseline results in one “healing donation” to the fund. The “relief kits” contain hygiene products as well as Vaseline. Families and first responders are eligible to receive them.
The fund also supports “healing stations” in various countries.
By the end of 2016, the program had touched more than 1.5 million lives.
