简要总结
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.
详细描述
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.

研究组 & 干预措施
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.
干预措施: Safety Behavior Fading for Appearance Concerns (Behavioral)
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.
干预措施: Progressive Muscle Relaxation (Behavioral)
