PROJECT SUMMARY – BEHAVIORAL SCIENCE AND ANALYTICS CORE The UAB NORC Behavioral Science and Analytics Core fulfills the need among nutrition and obesity researchers for guidance in developing study designs, consultation for statistical analysis, and development of new statistical methods to answer the unique questions posed by NORC investigators. It also provides consultation and assistance with behavioral techniques to support the development and delivery of behavioral and other clinical interventions for nutrition- and obesity-related conditions. We will guide investigators in the selection of theoretically-grounded and empirically-informed interventions; assist with decisions related to intervention dose, modality, and content; and offer resources and staff to deliver selected interventions. The core also supports the selection and implementation of study designs to evaluate behavioral constructs and outcomes in nutrition/obesity research. We will provide consultation and support in developing obesity-related behavioral studies and assist with the selection of study design, including quantitative, qualitative, and mixed methods; sample size estimation; and choice of behavioral assessments using quantitative and qualitative methods. The core provides electronic data capture and data management support for nutrition/obesity studies. We will assist in implementing data capture systems for trials and observational studies, which would include setting up electronic case report forms, integrated implementation of randomization techniques including minimization, and integration of wearable and remote data collection technologies such as integrated voice response and text message for remote collection of behavioral data. Finally, the core provides data analyses consultation and support for behavioral studies related to nutrition/obesity.
