Brief Summary

College women are at risk for eating disorders, which have profound health impacts. Cross-sectional studies have shown that the use of dietary self-monitoring is associated with eating disorder risk among college students. However, causality cannot be established with cross-sectional studies.

This study utilizes a randomized controlled trial design to examine how the use of a popular dietary self-monitoring smartphone application impacts college females' well-being, including eating disorder risk. We hypothesize those who are randomized to dietary self-monitoring will have a greater increase in eating disorder risk compared to the control group.

Arm && Interventions

Group	Intervention	Description
Intervention	Dietary self-monitoring	Participants are instructed to use a popular dietary self-monitoring application on their smartphone for one month.

Primary Outcome Measures

Name	Time	Method
Eating Disorder Risk	30 days	Measured via survey using the validated SCOFF questionnaire which consists of five questions. Each question is a yes/no and a yes receives one point with a total score ranging from 0-5. Higher scores indicate higher risk. Modified to ask about pounds instead of stone as a measure of weight.

Secondary Outcome Measures

Name	Time	Method
Weight perception	30 days	Assessed using two questions on a survey pertaining to BMI category and weight.
Dietary Intake	30 days	Single item survey questions adapted from the Youth Risk Behavior Surveillance System
Weight Stigma	30 days	Measured via survey using five single item questions.
Weight	30 days	Blind weights taken on research grade laboratory scale.
Anxiety	30 days	State anxiety as measured via survey using the short-form of the state scale of the Spielberger State-Trait Anxiety Inventory. The scale consists of 6 questions with a range of scores 1-4 for each question. Three positive questions are reverse coded and scores are added together with higher scores indicating higher state anxiety.
Physical Activity	30 days	Single item survey questions adapted from the Youth Risk Behavior Surveillance System and an open ended question for amount of time physically active.
Weight-Related Self-Monitoring	30 days	Measured via survey that includes single item measures asking about physical activity self-monitoring and self-weighing frequency.
Body Image	30 days	Assessed via survey using the validated 6 question Body Image States Scale (BISS). Scores are the mean of the six items, three of which are reverse coded. Higher scores mean better body image states.
Depression Symptoms	30 days	Measured via survey using the Center for Epidemiologic Studies Depression Scale Revised (CESD-R-10). The CESD-R-10 is a 10 item scale with each question having the possibility of a score 0-3. Two questions are reverse coded, then scores from each question are added to give an overall score. Higher scores indicate more depressive symptoms.
Body changing intentions	30 days	Assessed using single item question on a survey asking how, if at all, participants wanted to change their body.
Social Media Use	30 days	Use of common social media sites assessed using five single item measures on a survey.
Subjective Quality of Life	30 days	Assessed using the Brunnsviken Brief Quality of Life Scale (BBQ) on a survey. The BBQ has 12 questions, each ranging from 0-4. Higher scores indicate higher subjective quality of life.
