Brief summary

Topic: Information on “functional nutrition” helps to reduce disordered eating. Functional nutrition is psychoeducation about the biological benefits of nutrition accompanied by a simple message: eat carbs regularly throughout the day. This randomised trial will compare a control condition to two intervention groups – both will receive a single session intervention containing psychoeducation about functional nutrition. One group will receive a goal setting exercise related to nutrition (i.e., indulging) and the second group will additionally be asked to think about current obstacles that impede the realization of the goal (i.e., mental contrasting). Evidence suggests that mental contrasting significantly increases the likelihood of behaviour change. Aims: 1. Can we replicate the effect of psychoeducation on disordered eating and body image? This would involve a comparison of the combined intervention groups with the control. 2. Does the use of mental contrasting produce significantly better outcomes than indulging or control in terms of goal attainment, disordered eating, body image, and mood? 3. Does weight concern status (low, high) moderate outcomes? Design: Conducted in first year Psychology students. Assessment will occur on three occasions: baseline (state and trait variables), immediately post-baseline after psychoeducation (state variables), 1-week post baseline (state and trait variables). We can categorise students as being at high or low risk of having disordered eating – using the 5-iem Weight Concern Scale.

Functional nutrition is psychoeducation about the biological benefits of nutrition accompanied by a simple message: eat carbs regularly throughout the day. This randomised trial will compare a control condition to two intervention groups – both will receive a single session intervention containing psychoeducation about functional nutrition. The psychoeducation will be delivered online via PowerPoint slides embedded on the Qualtrics survey platform incorporating interactive components (such as text entry questions and a small quiz to assess understanding). The anticipated duration of this psychoeducation is 15 mins. One group will receive a goal setting exercise related to nutrition (i.e., indulging) and the second group will additionally be asked to think about current obstacles that impede the realization of the goal (i.e., indulging + mental contrasting). Specifically, the indulging group will receive these instructions: "Imagine yourself looking ahead over the next week like a path stretching before you. At the end of this path is your wish, something that will be happening differently in your life. What is it? Name your wish in 3-6 words:" "Imagine yourself achieving this wish. Picture the scene in vivid detail—how does it feel to have achieved this? What does it say about you as a person?" Whereas, the mental contrasting group will receive these instructions in addition: Imagine yourself looking ahead over the next week like a path stretching before you. At the end of this path is your wish, something that will be happening differently in your life. What is it? Name your wish in 3-6 words:" "Imagine yourself achieving this wish. Picture the scene in vivid detail—how does it feel to have achieved this? What does it say about you as a person?" Although no homework is assigned, participants will be assessed to what extent they have met their nutritional goal at one-week follow-up using this question "In the last week, on how many days did you have at least 4 serves of carb, examples of serves are provided below. N Days ____" All questionnaires, psychoeducation and goal setting will be administered in an online self-guided format.
