Investigators Connecting Health and Social Media/mHealth

Our team is directed by Dr. Patricia Cavazos-Rehg, PhD, and Dr. Hannah Szlyk, PhD, who are currently conducting research on the uMAT-R app, which is a supportive app for individuals in recovery for substance use disorders. We also are researching other mobile app interventions that support individuals with mental health-related behaviors such as alcohol use, vaping, eating disorders, and depression.


Current Research Areas of Interest

uMAT-R: A mobile health (mHealth) app to support adults in recovery from substance use in Missouri and collect feedback to improve the app features- including projects focusing on the needs of pregnant and post-partum people and Black adults
Alcohol EMA: Developing an Ecological Momentary Assessment (EMA) app to learn more about associations between discrimination and alcohol use among Black young adults
VapeFree: Designing and evaluating an mHealth app intervention with a chatbot guide to reduce vaping behaviors among youth and young adults
Suubi mHealth: Addressing depression among adolescents living with HIV in Uganda with a mobile support app
Space from Body and Eating Concerns- Teen: Recruiting teens from social media and connecting them with treatment for eating disorders via an mHealth app
Cannabis Marketing: Assessing the online/social media presence of cannabis retailers and evaluating how exposure to cannabis-related content may impact public attitudes and cannabis use

Principal Investigators

Patricia Cavazos-Rehg, PhD

professor of psychiatry, principal investigator

Concerns about social media platform engagement and associations with mental health risk continue to increase, particularly among youth and young adults and those from minoritized groups. We are exploring innovative ways to utilize social media in mental health promotion and prevention initiatives. Recent and current studies include outreach and digital interventions for eating disorders, depression, alcohol use and vaping among youth and young adults on social media.

Hannah Szlyk, PhD, LCSW

assistant professor, department of psychiatry

Dr. Hannah S. Szlyk, PhD is a doctoral-level licensed clinical social worker (LCSW) with training in suicidology among underserved and minoritized populations and in qualitative and mixed methods study design and analyses. Her current work extends this research program to include mHealth interventions for SUD (e.g., opioid use disorder (OUD), alcohol, cannabis, and vaping) among adolescents and adults, and special populations, like pregnant and postpartum women and people. She is especially interested in understanding how mHealth tools can be used to amplify health equity. She holds graduate degrees in social work from Columbia University (MSSW) and the University of Texas at Austin (PhD) and received additional training at The Menninger Clinic and the Brown School (as a NIMH T32 postdoctoral fellow).

Recent Findings

Attitudes toward medication for opioid use disorder among pregnant and postpartum women and people seeking treatment.

In this study we learned about pregnant and postpartum women and people’s attitudes towards using medication for opioid use disorder (MOUD).

Exploring social media recruitment strategies and preliminary acceptability of an mHealth tool for teens with eating disorders.

We leveraged social media to connect with teens with EDs to pilot an mHealth tool. We found that using social media to recruit teens with EDs is feasible and may allow us to connect with groups who are more difficult to reach.
