Conclusions/limitations
- This study is the first RCT to show that patients with agoraphobia could benefit from mobile-based interventions.
- Limitations: There was no waitlist control group. Limited information was collected about participant characteristics; there were no data on comorbid disorders, other psychological or physiological treatments, or other demographic characteristics such as ethnicity or computer literacy.

The apps MoodTracker, ImproveYourMood, and ImproveYourMood+ deliver content “just in time” (in response to acute negative symptoms) to help patients with depression. In an RCT, Everitt et al7 evaluated delivering acute care for depressive mood states via a smartphone app. They sought to delineate whether symptom improvement was due to microintervention content, mood augmentation, or just-in-time prompts to use content.
Study design
- Participants (N = 235) from the general population who said they wanted to improve their mood were randomly assigned to a waitlist control group (n = 55) or 1 of 3 intervention groups: MoodTracker (monitoring-only; n = 58), ImproveYourMood (monitoring and content; n = 62), or ImproveYourMood+ (monitoring, content, and prompts; n = 60).
- The microintervention content provided by these apps consisted of 4 audio files of brief (2- to 3-minute) mindfulness and relaxation exercises. Participants used the assigned app for 3 weeks.
- Depressive symptoms, anxiety symptoms, and negative automatic thoughts were assessed at baseline, immediately following the intervention, and 1 month after the intervention using the 9-item Patient Health Questionnaire (PHQ-9), 7-item GAD scale (GAD-7), and 8-item Automatic Thoughts Questionnaire, respectively.
Outcomes
- Compared to the waitlist control group, participants in the ImproveYourMood group showed greater declines in depressive symptoms and anxiety symptoms (at follow-up only), and negative automatic thoughts (at both postintervention and follow-up).
- Those in the ImproveYourMood+ group only showed significantly greater improvements for automatic negative thoughts (at postintervention).
- MoodTracker participants did not differ from waitlist controls for any variables at any timepoints.
