Intervention in Depression: Randomized Control Trial Examining a Fully Automated Mobile Behavioral Activation Intervention

Participants in the experimental (BA) condition will complete an introduction video about the intervention. They will then take a pre-intervention survey, after which they will choose five enjoyable activities from a large list. Daily text message reminders will be sent to BA participants in the morning to remind them to do their enjoyable activities for the day, as well as a link to a checklist where they will report how frequently they have completed any of their five activities from the previous day (example text message in documentation). At the end of the month, they will complete a follow-up survey consisting of the same measures from the pre-intervention survey.

Participants in the active control condition will complete mostly the same tasks as those in the experimental (BA) condition. They will then take a pre-intervention survey and choose five enjoyable activities from the same list; however, active control participants will not explicitly be asked to complete these activities for the intervention. Instead, participants in the active control condition will be promoted to complete tasks such as drinking more water, going to bed early, brushing their teeth, showering or bathing for that day, and eating well balanced meals. Daily text reminders will be sent about these healthy living activities in the morning. In that same message, they will receive a link to a checklist where they will report about their completed healthy living activities for the previous day (example text message in documentation).At the end of the month, they will also complete a follow-up survey consisting of the same measures from the pre-intervention survey. Importantly, participants in this condition will have the option to complete the BA digital intervention after completing the active control condition if they desire; however, these participants would not be paid for their time upon completing the BA intervention.

Finally, participants in the passive control condition will complete mostly the same tasks as those in the experimental (BA) and active control conditions. They will take a pre-intervention survey and choose five enjoyable activities from the same list; however, passive control participants will not explicitly be asked to complete these enjoyable activities or any of the healthy living activities during the month. To further clarify, passive control participants will not be enrolled in SlickText and will therefore not be sent daily text reminders or checklists. At the end of the month, they will also complete a follow-up survey consisting of the same measures from the pre-intervention survey. Importantly, participants in this condition will also have the option to complete the BA digital intervention after completing the passive control condition if they desire; however, these participants would not be paid for their time upon completing the BA intervention.
