T2 Mood Tracker is an app designed to help users track their emotions over time. It comes with six pre-installed areas: Anxiety, Depression, Well-Being, Head Injury, Post-Traumatic Stress, and Stress. Users can also add and customize additional scales. T2 Mood Tracker compiles the user’s ratings in each of these areas and creates a graph that can be printed or shared directly with a treatment provider. There is also space to note important or meaningful events during the day. This is intended to help users and their providers see patterns and identify triggers in the user’s daily life. Users can also connect their FitBit data to see that information directly within the app and observe any relationship between exercise and mood.

Research on this App

No direct research has been done about the efficacy of T2 Mood Tracker. There have been a few studies about the usability and acceptability of the app.

In a study published in 2019, a small scale usability test was conducted which involved recruiting nine army interns and residents to serve as proxy patients. The System Usability Scale (SUS) was used to rate subjective usability along with focus groups and self-report questionnaires. Proxy patients rated the mobile app as acceptable on the SUS, with average usability and above average learnability. (McCreight, S. J., Brinton, C., Kinn, J., Bush, N., & Hoyt, T. 2019.

In a study published in 2014, T2 Mood Tracker was test in a small sample of redeployed soldiers (n=8, 5 male) under treatment for behavioral health issues. Participants used the app an average of 10 different days over the 2- to 3-week test period. At the end of the study, participants were asked to rate their experience with qualitative feedback, quantitative self-reports (e.g., Likert scales), and to provide usage logs. The study found that T2 Mood Tracker was easy to use, useful and beneficial. (Bush, N. E., Ouellette, G., & Kinn, J. 2014.
