April 9, 2026 updated by: University of Kansas Medical Center

The Firefly Mobile App: A Digital Health Solution for Healthy Sleep in Teens

The goal of this study is to form a Teen Advisory Board (TAB), who will partner with our study team to co-design a beta-test a new prototype of the Firefly program, a mobile-native insomnia cognitive behavioral therapy intervention for teens. This new prototype will have addressed issues that adolescents who had used the first version of the program deemed to be barriers to engaging with the treatment.

Detailed Description

The aims of this study are to: 1) form a Teen Advisory Board (TAB) of teens with self-reported insomnia symptoms, 2) co-design a functional app prototype for sleep with TAB, 3) conduct two rounds of beta-testing to inform the iterative refinement of the app prototype. Participants will include 40 youth and their parents; 10 youth will participate in the TAB and first round 1 of beta-testing, and a separate cohort of 30 youth will participate in a second round of beta-testing. Youth will be ages 13-18 years and will have self-reported insomnia symptoms.
