Text Message Treatment for Social Anxiety

Study Overview
=================
Brief Summary
-----------------
This is an intervention study designed to evaluate a text message based safety behavior fading treatment for people with social anxiety disorder.

Detailed Description
-----------------
This study hopes to assess whether a month long text message based safety behavior fading protocol is effective in reducing safety behaviors and social anxiety symptoms. Over the course of four consecutive weeks, text messages will be sent to participants the first day of the study and every other day for four weeks (14 texts in total). These text messages will remind participants to either avoid using their three most engaged in safety behaviors (assessed at pre-treatment) or to stay present-focused. The past week frequency of the participants' safety behaviors will be assessed at the beginning of pre-treatment, post-treatment, and four week follow up assessments Participants will be asked to complete an additional online questionnaire for both a post-treatment and a 4-week post-treatment follow up assessment. We hypothesize that: 1) the safety behavior group will show a greater overall reduction in social anxiety symptoms, 2) that the safety behavior group will show a reduction in the frequency of safety behavior use, and 3) that the present-focused group will show an increase in mindfulness.

| --- | --- |
| Experimental: Safety Behavior Fading<br>Participants are asked to pick their three most common safety behaviors from a list and then receive texts every other day for a month reminding them to fade those behaviors. | Behavioral: Safety Behavior Fading<br>* Participants are asked to fade their three most common safety behaviors associated with their social anxiety<br>|
| Active Comparator: Present Centered<br>Participants receive texts every other day for a month asking them to try to focus on the present that day. | Behavioral: Present Centered<br>* Participants are asked to try to increase their focus on the present.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Social Phobia Inventory (SPIN) | Self-report scale that measures Social anxiety symptoms. Scores range from 0 to 68 with higher scores indicating higher levels of social anxiety symptoms. | Change in social anxiety symptoms from baseline to post treatment (4 weeks) and one month follow up (8 weeks) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Subtle Avoidance Frequency Examination(SAFE) | Self report scale used to assess how often people use safety behaviors to cope with their anxiety. Scores range from 33 to 165. Higher total scores are associated with more frequent safety behavior use. | Change in safety behavior use from baseline to post treatment (4 weeks) and one month follow up (8 weeks) | 
| Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) | Self-report used to measure mindfulness, including awareness of thoughts and feelings. Total scores range from 12 to 48 with higher scores indicating a greater ability to be mindful, present in the moment, and aware of thoughts and feelings. | Change in mindfulness from baseline to post treatment (4 weeks) and one month follow up (8 weeks) |
