Discuss the findings of a study that utilized BIG data, economic theory and a social media intervention aimed to improve nutritional behavior of college students. Millions of data points were collected to provide insight into daily food choice through a centralized Point-of-Sale system (32-weeks of daily meals purchased for over 3,700 emerging adults). This data then informed a 12-week intervention measuring the efficacy of FB, Instagram, SnapChat, and Slingshot to influence eating behaviors.

    8. 8. Research Study 32-weeks collecting BIG nutritional data Focus groups informing a: 12-week nutritional change intervention Analysis Nutritional Economic Social media efficacy
    9. 9. BIG Data Who & What 3,700 students purchase data for 32-weeks. Millions of data points collected. Millions of dollars spent. Where Every on-campus point of sale for prepared food When Fall 2014 – Spring 2015 Why Set a baseline for current nutritional purchase (via caloric intake, USDA food grouping, etc.)
    10. 10. Econ Analysis AIDS Model
    11. 11. Nutritional Data match All menu items will be matched nutritionally to the student USDA Caloric intake
    12. 12. 12-week intervention
    13. 13. Recruitment of Participants 450 students recruited Fall 2014 Pre-data collected (BMI, weight, questionnaire = $25 incentive) Post-data (BMI, weight, questionnaire = $25 incentive)
    14. 14. Recruitment of Participants 75 assigned to each group 75% engagement = $50 incentive Engagement = follow and engage with assigned medium
    15. 15. Experimental Design & Group Assignment
    16. 16. 12-week intervention 2 nutrition messages delivered per week (specific to campus dining locations) To receive a $50 incentive participants must respond to 75% of the messages: Instagram group must like SnapChat group must view Slingshot group must SnapBack their most recent meal Facebook group must like Face-to-face group must attend in person Control group – no enrollment or action
    17. 17. Example
    18. 18. Social media purposefully chosen for this study for graduated levels of engagement Facebook = Baseline (many nutrition educators and dining facilities use it) Instagram = passive (only have to “like”) SnapChat = moderate engagement (must watch before it dissappears FOREVER) SlingBox = high engagement (must sling-back photo so see our message) Face-to-face = traditional education medium Control = gotta have it for strong research design ;-)
    19. 19. Analysis Engagement level with medium Efficacy of each medium Maximum payoff for administrators of social media accounts Nutritional Change pre-, during, post- study Economic Theory Application (AIDS Model)

    21. 21. Greg Heiberger, Ph.D. Dr. Heiberger is an engaged and analytical leader in the research, design and implementation of emerging technologies into the higher education learning environment. He has 10 years of experience in higher education - spanning university administration, teaching and research in both academic and student affairs. He has won numerous awards from his peers and students for his rigorous and engaging teaching and advising. Dr. Heiberger was also recently names an HHMI & National Academies of Sciences Education Fellow. Greg’s research-to-practice approach has spanned projects including one of the first studies examining Facebook and student involvement theory, Twitter’s impact on college student engagement and more recent research analyzing the impacts of social media in micro-aggressions with under-represented students and the impacts of iPads in collaborative learning environments. He is at the forefront of researching the impact of new technology and social media in emerging adulthood.
    22. 22. Lacey McCormack, Ph.D., MPH, RD, LN, HFS Dr. McCormack has a background in public health nutrition and holds a PhD in nutrition from South Dakota State University. In addition, she is a licensed, Registered Dietitian and an American College of Sports Medicine certified Health/Fitness Specialist. She has spent over 10 years in research, spanning a variety of positions and responsibilities, building a solid understanding of how to design, conduct and disseminate research. She has worked on an observational study that’s followed over 1,200 rural individuals in South Dakota for almost 10 years and directed the implementation of the multi-state, multi-million dollar NIH funded research study. She has played a role in multiple cross-sectional and behavioral intervention studies and has experience crafting study designs, securing funding and collecting, managing, analyzing and publishing data. Her nutrition expertise and research background positions her well for overseeing nutrition-related aspects of this project (including social media messaging) and in study design and analysis.
    23. 23. Kuo-Liang (Matt) Chang, Ph.D. Dr. Kuo-Liang “Matt” Chang holds a Ph.D. in Economics from University of Utah. His expertise is in the areas of consumer economics and value identification, with an emphasis on agricultural products that contribute to the profits and sustainability of regional economy and local community. Dr. Chang’s background is very relevant to this project because much of the research he has conducted has involved with research methods that examine consumers’ behavior and producers’ price strategies. He is also very interested in studies of how financial incentives affect consumers’ behavioral towards unhealthy consumption such as tobacco, betel, and alcohol.
