This paper discusses challenges in utilizing findings and constructs from different (health behavior) theories. There is a multitude of theories that can be used, but the question is what to do with so many theories. As a result there is debate about the need for integrating health behavior theories. Opponents of integrating theories suggest that this may lead to a theory of everything without adding anything. Supporters, however, see advantages of such an approach. Integration is more than simply combining theories. Combining theories implies using a simple additive model. Integration, however, implies critical testing of these constructs, and constructs will only be added if they have supplementary value theoretically and empirically and will lead to developing and testing new hypotheses. This paper outlines what the advantages of critical testing and integration of theories could be, using the Integrated-Change Model as an example.
