IVR-Based Physical Activity Intervention
The M.I.N.D. lab team is designing a physical activity intervention to be administered via an Interactive Voice Response (IVR) system and cell phones. The intervention encourages post-menopausal women to increase number of steps per day. Besides increased physical activity, endpoints include increased consumption of fruits and vegetables, and the changes in cancer-related biomarkers. This project is funded by the Breast Cancer Research Foundation (BCRF).

The M.I.N.D. lab team is collaborating with an interdisciplinary team of researchers drawn from public health, oncology, physical activity, and communication to develop a tailored intervention. Using self-management as the key variable within a goal-setting and problem-solving framework, the intervention aims to encourage sedentary, post-menopausal women to become active. Often, technology solutions designed with good intentions do not produce the intended outcomes. Despite the conveniences and advantages offered by technology, some technology-based interventions are not as effective as comparable interventions administered via a health coach. The social contracting and accountability that comes with human interaction is missing in human-computer interaction. We address this by introducing a health coach in one of the intervention conditions. The role of the coach is to offer social support and to explain and reiterate the tailored messages. Messages from the coach and to the coach are managed through the Interactive Voice Response system. In addition to innovative use of IVR technology, we also test whether cell phones can be used to capture Ecological Momentary Assessments (EMAs). Further, self-reports of physical activity are validated through a pre-post 1-mile walk test and other biomarkers, such as lipids and IGF-1.
