Study 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.

Read the 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.

Study arms

  • Experimental
    Safety Behavior Fading

    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 engaged in each safety behavior over the previous day.

  • Active comparator
    Progressive Muscle Relaxation

    Participants in this condition will be instructed to try and practice progressive muscle relaxation daily for 28 days. To match safety behavior fading 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.

What researchers measure

Primary outcomes

  1. The Social Appearance Anxiety Scale (SAAS)

    Self-report scale that measures appearance anxiety symptoms. Scores range from 16 to 80 with higher scores indicating higher levels of appearance concerns.

    Time frame: Day 0, Day 28, Day 56

  2. Appearance Behaviors Checklist past-week version (author constructed)

    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

    Time frame: Day 0, Day 28, Day 56

  3. Appearance Anxiety Inventory (AAI; Veale et al., 2014)

    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.

    Time frame: Day 0, Day 28, Day 56

  4. Social Phobia Inventory (SPIN; Connor et al., 2000)

    Self-report scale that measures social anxiety symptoms. Scores range from 0 to 68 with higher scores indicating higher levels of social anxiety.

    Time frame: Day 0, Day 28, Day 56

  5. Eating Disorder-15 (ED-15; Tatham et al., 2015).

    Self-report scale that measures eating disorder symptoms. Scores range from 0 to 90 with higher scores indicating higher levels of eating pathology.

    Time frame: Day 0, Day 28, Day 56

  6. The Eating Disorder Inventory-Body Dissatisfaction (EDI; Garner et al., 1983).

    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.

    Time frame: Day 0, Day 28, Day 56

  7. Credibility and Expectancy Questionnaire (CEQ; Devilly & Borkovec, 2000).

    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.

    Time frame: Day 0

Secondary outcomes

  1. Center for Epidemiologic Studies Depression Scale-10 (CESD; Andreson, 1994)

    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.

    Time frame: Day 0, Day 28, Day 56

  2. Generalized Anxiety Disorder-7 (GAD-7; Spitzer et al., 2006)

    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.

    Time frame: Day 0, Day 28, Day 56

  3. Appearance Preference Task

    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.

    Time frame: Day 0, Day 28, Day 56

  4. Social Interaction Scale (Author Constructed)

    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)?"

    Time frame: Day 0, Day 28, Day 56

  5. Body Dysmorphic Disorder Symptom Scale-Cognitive Subscale (Wilhelm et al., 2016)

    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.

    Time frame: Day 0, Day 28, Day 56

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2026 (actual). Primary completion is estimated for Dec 2026, 7 months after the start.

Of 26 interventional studies with no phase under Body Dysmorphic Disorders, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 34. This study's planned 7 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
