Digital therapy apps improve mental health support for college students

The researchers found that students receiving the digital intervention were more likely to report being symptom free at the six-week, six-month and two-year marks, and that these students were more likely to engage these services compared to the campus referral group. Specifically, services uptake - or when a person actually receives a service - was seven times greater for college students assigned to a digital intervention than to on-campus clinic referrals. Approximately 74% of individuals given access to the digital intervention started the program, compared to 30% of individuals who were given a referral to a campus clinic and received at least one therapy session or a new medication prescription.

Michelle Newman, lead author, professor of psychology and psychiatry at Penn StateOne of the challenges with any digital intervention is that people sometimes download an app but then do not use it. We were also interested in learning the extent to which people actually received services after being randomized to the app or on-campus counseling center. We found that uptake was significantly better in the digital intervention than referral to the counseling center."

To test the effectiveness of the digital intervention, the researchers worked with 26 colleges and universities across the U.S. to send an email to the entire student body - what researchers call a population-level approach - inviting them to take part in a mental health screening. Of the 39,194 individuals who completed the screening, 6,205 had clinical levels of or were at high risk for developing generalized anxiety disorder, panic disorder, social anxiety disorder, depression or an eating disorder. Those individuals completed an additional baseline survey and were randomized into one of two groups. One group received access to the coached digital intervention for six months, while the other group received referrals to their campus counseling center.

The therapy app offered six to eight 20-minute-long modules for each mental health problem. Participants in the digital therapy group completed an average of 2.4 modules and received about 15 messages from a trained therapy coach. Newman explained that individuals in the digital therapy group began with modules addressing their main mental health concern and then worked with their coaches to receive additional modules that addressed co-occurring issues.

For example, compared to the campus referral group, those who used the digital intervention had a 4.3% lower prevalence of having any mental health disorder at the six-week mark, 4.9% lower prevalence at the six-month mark and 3.8% lower prevalence at the two-year follow-up. This result showed that the coached digital intervention both prevented the development of new disorders as well as treated disorders that were present before the intervention.

The population-level screening and digital therapy approach can complement existing in-person services beyond college campuses, Newman said.

"This approach could potentially be used anywhere where you have access to a full population in terms of email addresses, like at a company, to help disseminate mental health services that people might not think about seeking," she said, explaining that the proactive screening process taken in the study helped individuals prevent disorders for which they were at high risk of developing and treated disorders for which they may not have sought face-to-face services.
