• Title: A Personalized Health Behavior System to Promote Well-Being in Older Adults

• Summary: The project addresses the needs of the aging U.S. population, which is expected to increase significantly by 2040. It focuses on vulnerable groups such as the oldest old, minorities, and those of lower Socio-Economic status (SES), who are at risk for social isolation, poor diet, and decreased physical activity. The study will utilize mobile and tablet-based technologies to deliver personalized behavior-change programs and social support. The Fittle Senior System (FSS) developed will provide online social interactions and adaptively coach users for better diet and increased physical activity.

• Study Phases:

  • Phase 1: Development and pilot testing with representative samples of older adults.

  • Phase 2: Two-group randomized trial comparing FSS against a paper-based educational control, including a 12-week active intervention followed by a 12-week maintenance phase.

• Participants: 180 community-dwelling adults aged 65+ who live alone and are at risk for social isolation.

• Assessments: Participants will be assessed at baseline, post-intervention (3 months), and post-maintenance (6 months) for health behaviors and social support.

• Public Health Relevance: The project aims to improve management of chronic conditions such as hypertension, diabetes, and obesity among diverse older adults through a technology-based intervention.

• SCH: INT: Collaborative Research: FITTLE+: Theory and Models for Smartphone Ecological Momentary Intervention

• Summary: This interdisciplinary project aims to refine and extend existing health behavior change theories into fine-grained, predictive computational models for use in smartphone platforms. Fittle+ will utilize Ecological Momentary Intervention (EMI) to enhance diet and physical activity through autonomously planned personalized coaching and social support, utilizing mobile sensing and cognitive tutoring.

• Challenge: The project seeks to overcome limitations in current behavior-change methodologies by leveraging the capabilities of smartphones for detailed measurement and intervention.

• Research Team: Includes experts in mobile sensing, artificial intelligence, computational cognition, social psychology, human-computer interaction, computer tutoring, and measurement theory.

• Collaboration: The research involves collaboration with weight-loss interventionists at a major health organization in Hawaii.

• Featured: NSF Research News, July 24, 2015

• Goal: Develop a scientific smartphone tool that supports personalized health interventions based on individual user data and predictive models.
