Answer to Question 1

ANS: C
The natural history of disease model explains disease from prepathogenesis through resolution of the disease process. The epidemiological model involves the epidemiological triangle: agent, host, and environment. The ecosocial model emphasizes the role of evoloving macro-level socio-environmental factors to understand health and illness. The wheel model subscribes to multiple-causation rather than single-causation disease theory, and is more useful in analyzing complex chronic conditions and identifying factors that are amendable to intervention.

Answer to Question 2

ANS: B
Evaluation includes reflecting on each previous stage to determine strengths and weaknesses. Process evaluation, also called formative evaluation, would allow one to change the project while it is being implemented. By collecting data one month after the project starts, it will be hard to determine if the desired outcomes are being met. Aggregate involvement is not increased by filling out evaluation forms one month after project implementation. Collecting data one month after project implementation is not typically completed to assure ongoing funding.
