a potentially effective approach to preventing illness and disability and promoting health in this vulnerable population." 10 To test this hypothesis, they randomly assigned 361 seniors living in two large, government-subsidized apartment complexes to one of three groups: an occupational therapy intervention group, a social activity group and a group which received neither service. The occupational therapy group attended a group program two hours each week for nine months. In the groups, participants examined the role of everyday activities in maintaining their health and well-being and analysed how best to incorporate health-promoting activities. Seniors in the social group spent a similar amount of time in planned activities designed to increase their interaction with one another. The third group received no intervention. At the end of nine months, the occupational therapy group felt better mentally and physically, and reported a higher life satisfaction. Further analysis demonstrated that the occupational therapy group used fewer medical services during the six-month follow-up period. 11 Clearly, occupational therapy is an essential service in the community, promoting continued participation in daily activities throughout the life span despite acute and/or chronic conditions.
