Brief summary
The current study aims to explore the efficacy of a text message based safety behavior fading intervention compared to a progressive muscle relaxation intervention for appearance concerns.
Detailed description
Appearance-related safety behavior fading intervention procedures will follow methodology previously used in the Cougle Lab. The safety behavior fading intervention is designed to target a decrease or elimination of appearance-related safety behaviors. Individuals randomly assigned to the safety behavior fading condition will receive instructions to decrease or eliminate their endorsed appearance-related safety behaviors. In addition, they will receive daily reminders via text message to decrease these behaviors, along with a safety behavior monitoring checklist in which the participant indicates the extent to which they decreased and/or eliminated each safety behavior over the previous day. The daily reminder will include the following language: "Hi! This is a friendly reminder to avoid using your checklist behaviors. Please tap the link below to access today's checklist: \[link to checklist\]." Text messages will be delivered using EZtexting a text messaging platform used for research and marketing. Note that no identifying information will be included in this platform. Each participants phone number will be accompanied with a anonymized ID code. Individuals randomly assigned to the progressive muscle relaxation condition will be instructed to try and practice it daily for the 28 days. They will also receive daily text messages to remind them to practice relaxation and they can log which of the 10 different muscle groups they tensed and released in the past day.
Interventions
Participants are asked to reduce or eliminate safety behaviors via text message reminders and checklists to monitor progress.
BEHAVIORALProgressive Muscle Relaxation
Participants are asked to practice relaxation daily via text message reminder and checklists to monitor progress.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The Social Appearance Anxiety Scale (SAAS) | Day 0, Day 28, Day 56 | Self-report scale that measures appearance anxiety symptoms. Scores range from 16 to 80 with higher scores indicating higher levels of appearance concerns. |
| Appearance Behaviors Checklist past-week version (author constructed) | Day 0, Day 28, Day 56 | Self-report scale used to measure frequency of engaging in appearance-related safety behaviors. This scale will be used as a manipulation check. Each item is rated on a 0 to 10 scale. Total scores range from 0 to 130 with higher scores indicating greater engagement in appearance-related safety behaviors |
| Appearance Anxiety Inventory (AAI; Veale et al., 2014) | Day 0, Day 28, Day 56 | Self-report scale that measures of body dysmorphic symptoms. Scores range from 0 to 40 with higher scores indicating higher levels of body dysmorphic symptoms. |
| Social Phobia Inventory (SPIN; Connor et al., 2000) | Day 0, Day 28, Day 56 | Self-report scale that measures social anxiety symptoms. Scores range from 0 to 68 with higher scores indicating higher levels of social anxiety. |
| Eating Disorder-15 (ED-15; Tatham et al., 2015). | Day 0, Day 28, Day 56 | Self-report scale that measures eating disorder symptoms. Scores range from 0 to 90 with higher scores indicating higher levels of eating pathology. |
| The Eating Disorder Inventory-Body Dissatisfaction (EDI; Garner et al., 1983). | Day 0, Day 28, Day 56 | Self-report scale for measuring body dissatisfaction for use in clinical outcome studies. Each item is rated on a 0-5 scale with a total score range of 9-54 with higher scores indicating greater drive for thinness, bulimia, and body dissatisfaction. |
| Credibility and Expectancy Questionnaire (CEQ; Devilly & Borkovec, 2000). | Day 0 | Self-report scale for measuring treatment expectancy and rationale credibility for use in clinical outcome studies. Three items are rated on a 0-10 scale and one item is rated on a 0-100 scale with higher scores meaning greater expectancy and credibility. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Center for Epidemiologic Studies Depression Scale-10 (CESD; Andreson, 1994) | Day 0, Day 28, Day 56 | Self-report measure of depression symptom severity. Each item is rated on a 0 to 3 scale. Total scores range from 0 to 30 with higher scores indicating greater depression severity. |
| Generalized Anxiety Disorder-7 (GAD-7; Spitzer et al., 2006) | Day 0, Day 28, Day 56 | Self-report measure of anxiety symptom severity. Each item is rated on a 0 to 3 scale. Total scores range from 0 to 28 with higher scores indicating greater anxiety severity. |
| Appearance Preference Task | Day 0, Day 28, Day 56 | Computerized forced-choice task measuring appearance importance relative to other favorable characteristics. The APT randomly presents a series of 33 word pairs and asks the participant to select the concept that is more important to them. Each pair consists of a positive appearance-related adjective and a positive character trait unrelated to appearance (e.g., beautiful-responsible). Higher scores indicate greater endorsement of appearance words. |
| Social Interaction Scale (Author Constructed) | Day 0, Day 28, Day 56 | Single-item self-report scale that the extent to which individuals engage with their social support networks. This question asks: "what percentage of your time awake did you spend interacting with others this past week (0% =No time at all, 100% =all of the time)?" |
| Body Dysmorphic Disorder Symptom Scale-Cognitive Subscale (Wilhelm et al., 2016) | Day 0, Day 28, Day 56 | Self-report scale that measures cognitions related to body dysmorphic disorder. Scores range from 0 to 190 with higher scores indicating higher levels of maladaptive cognitions related to body dysmorphic disorder. |
