|Title:||Compliance with Chronic Dietary Regimens: Measurement, Prediction, and Outcome|
|Authors:||Campbell, Allen Kent|
|Description:||Compliance has been defined as "...the extent to which a person's behavior coincides with medical or health advice" (Haynes, 1978, pp. 1-2) and is an important area of research in behavioral medicine. There are several key issues involved in compliance research. Specifically these are: 1) How do we define and measure compliance?; 2) how can we predict compliance?; and 3) does compliance lead to a better outcome than does noncompliance? This dissertation focuses on the question of what does psychology have to contribute to our understanding of these issues? The first study investigated the amount of agreement between the various definitions of dietary compliance in patients on hemodialysis. It demonstrated that one reason why there is so little agreement on the factors that predict compliance is that researchers in this area define compliance in very different ways. The second study explored the possibility of using outcome to provide an objective definition of compliance. It was found that dietary compliance is not related to outcome for hemodialysis patients. The third study focused on the use of self-efficacy to predict compliance in patients with Type 2 diabetes mellitus, a condition where dietary compliance may be easily measured. The results suggested that gender differences influenced the predictive power of self-efficacy. The interaction between gender and self-efficacy was confirmed in a laboratory task as well. Much of the experimental research on dieting and weight regulation ignores the potential impact of gender differences. The results of these studies suggest other paths for future research and also demonstrate that psychology can make a valuable contribution to research on compliance with chronic dietary regimens.|
