Treating Depression With Text Messaging

Study Overview
=================
Brief Summary
-----------------
The purpose of the research study is to investigate whether CBT-txt, a counseling program delivered by text messages is effective in stopping or reducing depressive symptoms. CBT-txt is based on a counseling program that has been proven to reduce depression when delivered in-person and on the web, but has not yet been tested or shown to be effective when delivered by text.

Detailed Description
-----------------
After being informed about the study and potential risks, participants will complete online screening assessments. Once eligibility is confirmed, participants will be randomized either to the intervention group or to the waitlist-control group. Those who are randomized to the intervention group will receive the 8-week text intervention via smartphone and complete assessments at baseline, 1 month, 2 months, and 3 months. Those who are randomized to the waitlist-control group will only complete the assessments at baseline, 1 month, 2 months, and 3 months. Participants who are initially assigned to the waitlist-control group can choose to receive the text intervention once their 3-month participation is complete.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Participants will be randomly assigned to either the treatment group or the waitlist control group. The treatment group will receive 8 weeks of the text based intervention (CBT-txt) and complete surveys at baseline, 1 month, 2 months and 3 months. The waitlist control group will only do surveys at baseline, 1 month, 2 months, and 3 months and will then have the option of receiving the intervention after their 3 months of study participation.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Treatment<br>This arm will receive 8 weeks of the text-based intervention (CBT-txt). CBT-txt is a version of Cognitive Behavioral Therapy tailored to be delivered by automated text message. This arm will also complete surveys at baseline, 1 month, 2 months, and 3 months. | Behavioral: CBT-txt<br>* Cognitive Behavioral Therapy delivered via automated text messaging.<br>|
| No Intervention: Waitlist Control<br>This arm will not receive the text-based intervention during study participation. These participants will only complete surveys at baseline, 1 month, 2 months, and 3 months and will be given the option to receive CBT-txt after they complete study participation. | |
