Current Research Areas of Interest

Substance Use

Many youth and young adults are exposed to substance use-related content via social media. We are using social media for insights into drug use behaviors, especially use of newly emerging drugs that are increasing in popularity. This information will help us understand how social media can be used for delivering substance use messages to young people.

Depression

As more and more people engage with social media, it is important to learn the motivations of individuals who publicly post about their depression, suicidal thoughts, and self-harm struggles via postings on social media. We are seeking to understand why this type of social networking occurs online and how it impacts users’ overall mental health.

Eating Disorders

There is increasing concern about online communities that promote eating disorder (ED) behaviors. We are exploring innovative strategies for online, accessible, and timely ED-related outreach that could facilitate novel ways to utilize social media in mental health promotion and prevention initiatives.

Recent Findings

Supportive social networking on Reddit

In this study we examine a supportive and accessible subreddit for individuals with the desire to quit cannabis use and highlight the potential of online communities as tools for individuals coping with addiction recovery.

Depression on Tumblr

We establish a baseline picture of the depression, self-harm, and suicidal ideation content on Tumblr that can serve as a starting point for discussions of this topic in the mental health community.

lmpact of Policy on Youth Tobacco Use

We confirmed that higher cigarette prices could help to reduce youth tobacco use behaviors. Several states still lag behind in terms of their low cigarette tax and should enact tax policies to reduce youth tobacco use.

Marijuana Advertising

We surveyed young adult marijuana users and over half reported viewing marijuana ads — either online or in more traditional forms of advertising such as billboards and print media.
