Abstract
The processes of change model has been successful in predicting behavior change across a wide range of both addictive and nonaddictive problem behaviors. This study was designed to examine the application of the processes of change model to weight control. Study participants included 285 women and men enrolled in three community-based weight loss programs. Results based on structural equation analyses showed that the processes of change model fit the data better than several plausible alternative models. In addition, structural analyses revealed the existence of two general (higher order) processes of change for weight control, the experiential and behavioral processes. These results are similar to those previously reported for eight other problem behaviors. Limitations of the current work and future directions for this line of research are discussed.
