My research applies social psychological theories to predict and change health behaviors. I study the theory-based effects of psychological constructs such as attitudes, intentions and motives, self-efficacy, perceived control, self-control, habit, planning, and personality traits on health behavior, and how health professionals can use data on these effects to promote health behavior change through intervention. I am also interested in developing and advancing psychological theory through theoretical integration, particularly the integration of constructs and process from social cognition theories, theories of motivation, and dual-process and dual-phase models. In addition, I am interested in research synthesis, particularly testing predictions of psychological theory across multiple populations, contexts, and behaviors using meta-analysis.
