While extensive research has been conducted in the field of health enhancing behavioral change, the factors contributing to the maintenance of healthy lifestyle modifications remain relatively unknown. This is a crucial theoretical and empirical shortcoming, because, on one hand, in the long run of behavioral change attempts, relapsing into a previous bad habit or unhealthy behavior seems to be the rule rather an exception and, on the other hand, short term changes are not sufficient to reduce rates of morbidity and mortality. Attempting to address this gap, the current research proposal will investigate factors which may contribute to sustaining the adoption of healthy behaviors, by means of experience sampling. A promising theoretical assumption is that behavioral maintenance depends on one’s feeling of satisfaction with the outcomes of behavioral change (Rothman et al., 2004); however, the predictors of satisfaction are still unknown. The field of interest is physical activity and healthy eating, reflecting recent advances which stress the benefits of targeting multiple behavioral components simultaneously (e.g. Blue, & Black, 2005).
