Theories and model provide different ways of understanding psychological phenomena. While theories help us understand and explain phenomena, models provide an overview of the structure of phenomena. Both are useful for guiding research and generating hypotheses to test.
Over the past 20+ years I have proposed and tested several theories and models to inform research. A brief summary of each model along with the supporting scientific article(s) are presented by clicking the links below.
The Procrastination-Health model
The procrastination-health model (Sirois et al., 2003; Sirois, 2007) is the first model to explicate the links between chronic procrastination and physical health. The model proposes that procrastination confers risk for poor health through both a stress-related route and a behavioral route. However, cross-sectional and longitudinal research suggest that stress is the key pathway linking procrastination to poor health.
