Study Protocol 
The study will take 3-6 months and will consist of the following: 
● Participants will complete a 1.5 hour enrollment session including the informed consent 
process, self-report questionnaires, phone set-up, and a phone usage and safety briefing.  
● Over the course of 3 months, participants will have access to automated self-help 
interventions designed as a kit of smartphone tools, which are based on principles of 
cognitive-behavioral therapy. Participants will also have access to three services that will 
connect them with a real person if they need emotional support. 
● Participants will have the opportunity to complete two optional 30-minute interviews at 2 
weeks and 4 weeks into the study period. 
● Participants will also be asked to complete a daily survey and rate a daily tip via a mobile 
app. 
● At the 3-month point of the intervention, participants will be asked to complete another 
series of self-report questionnaires. If these questionnaires are completed with valid 
responses, participants will receive another 3 months of paid phone service and study 
participation will be extended to 6 months.  
● At the end of the 6-month period, participants will be asked to complete an endpoint 
assessment consisting of self-report questionnaires. A $25 incentive will be offered for 
completing this assessment. 
 
 
Statistical Analysis Plan 
● We will examine usage of the mobile applications, ratings of acceptability, and ratings of 
perceived benefit.  
● We will conduct paired t-tests to assess pre-post change in posttraumatic stress disorder, 
depression, anxiety, substance use, risky behaviors, satisfaction with life, and 
psychosocial flourishing.
