Social media is an exciting new space to learn about health behaviors and attitudes in ways that avoid the response bias in traditional research methods. Our team engages in novel data mining, natural language processing, and network dynamics methodologies to understand how individuals and populations communicate about health on social media. In addition to self-reporting behaviors and attitudes, social media allows for the development of virtual communities that allows for individuals who identify with particular behaviors, attitudes and sentiments to discuss topics of interest, which can then be identified for researchers studying these groups. For hard-to-reach populations, social media is particularly useful in filling in gaps in the research regarding health behaviors and attitudes that may carry stigma or are understudied more generally. To compliment our research activities, we are also at the cutting-edge of using social media to positively influence health behaviors online.
Our team has leveraged social media data to study an array of topics, including: cervical cancer screening, opioid misuse and cancer survivorship.
