Theory Development and Integration

 

Trans-Contextual Model. Together with my colleague Nikos Chatzisarantis, I have developed an integrated model that explains the processes by which autonomous motivation and autonomy support for activities (e.g., physical activity, learning) in an educational setting relates to autonomous motivation, attitudes, and intention toward, and actual participation in, activities outside of school. The model has been applied in numerous educational contexts (e.g., physical education classes, math and science lessons) and extra-mural behaviors (e.g., physical activity, math and science homework).

Theory Integration. I am keen on the integration of theories to address shortcomings of current theory, such as redundancy across constructs and boundary conditions, and, in so doing, facilitate more comprehensive, effective prediction of behavior. In particular I am interested in integrating theories such as self-determination theory with theories of social cognition like the theory of planned behavior and reasoned action approach, and incorporating constructs that represent non-conscious processes (e.g., implicit attitudes, habit) as behavioral determinants within current social cognition models.

Synthesis and Development of Theories

 

Testing Theories Using Meta-Analysis. A key strand of my research is testing key hypotheses from social psychological theories, particularly theories that have been applied to health behaviors using meta-analysis. The aim is to examine the cumulative evidence for theory predictions across the extant literature to provide an overview of the general efficacy in predicting behavior. The research also enables testing of whether theory effects vary across contexts according to key methodological and theoretical moderating variables. The typical approach to doing this is through meta-analysis, including means to test theories across studies using meta-analytic structural equation modeling and path analysis.

Development of Theory-Based Behavior Change Interventions

 

Alongside theory testing and development, I also focus on leveraging these theoretical insights to develop effective health behavior change interventions. I am currently involved in multiple grant-funded projects aimed at developing, implementing, and evaluating theory-based behavior change interventions in multiple contexts, populations, and behaviors.
