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 Intervention/treatment
Experimental: Intervention
Participants are instructed to use a popular dietary self-monitoring application on their smartphone for one month.
Other: Dietary self-monitoring
Participants use a popular smartphone application to track their food and drink intake for one month.

No Intervention: Control
Participants are not asked to use the smartphone application.

Primary Outcome Measures :
  1. Eating Disorder Risk [ Time Frame: 30 days ]
    Eating disorder risk will be measured on a survey via the Eating Disorder Examination Questionnaire Short Form (EDE-QS). The EDE-QS is a validated 12 question scale. Each question has a score range 0-3, and the average of all scores is the overall score. A higher score indicates higher risk.

  2. Eating Disorder Risk [ Time Frame: 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 :
  1. Weight-Related Self-Monitoring [ Time Frame: 30 days ]
    Measured via survey that includes single item measures asking about physical activity self-monitoring and self-weighing frequency.

  2. Body Image [ Time Frame: 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.

  3. Weight Stigma [ Time Frame: 30 days ]
    Measured via survey using five single item questions.

  4. Dietary Intake [ Time Frame: 30 days ]
    Single item survey questions adapted from the Youth Risk Behavior Surveillance System

  5. Physical Activity [ Time Frame: 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.

  6. Weight perception [ Time Frame: 30 days ]
    Assessed using two questions on a survey pertaining to BMI category and weight.

  7. Body changing intentions [ Time Frame: 30 days ]
    Assessed using single item question on a survey asking how, if at all, participants wanted to change their body.

  8. Social Media Use [ Time Frame: 30 days ]
    Use of common social media sites assessed using five single item measures on a survey.

  9. Weight [ Time Frame: 30 days ]
    Blind weights taken on research grade laboratory scale.

  10. Subjective Quality of Life [ Time Frame: 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.

  11. Anxiety [ Time Frame: 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.

  12. Depression Symptoms [ Time Frame: 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.
