I investigate how and why people initiate behavioral change and factors which promote the maintenance of newly adopted behaviors, especially among adults with prediabetes or type 2 diabetes. Mechanisms for promoting behavioral change are examined to identify those most potent. These mechanisms of change are incorporated into behavioral lifestyle interventions for evaluation. The relationship among and intervention impact on psychosocial, dietary, physical activity, and clinical outcomes are determined to develop more effective interventions. Variation in intervention outcomes also is examined to better tailor lifestyle interventions for subgroups of interest. Both qualitative and quantitative research methods are incorporated into intervention development and evaluation.
