Biasing Food Value Construction for Anorexia Nervosa
This study is looking at whether a simple training task can help people with anorexia nervosa make food choices more like healthy eaters. You would view images of foods and focus on different qualities, like how tasty or healthy they are. Researchers want to see if this training can change how important tastiness versus healthiness is when you decide what to eat. This study is for individuals aged 16 to 45 who can read and speak English. The goal is to see if this training can make food choices more similar to those of healthy eaters. The current recruitment status is unclear.
- Study design
- This is an interventional study planning to enroll 150 participants. It involves a behavioral intervention where participants focus on food attributes.
- What's involved
- You would participate in a training session where you view food images and focus on their attributes. Immediately before and after this session, you would complete assessments, all on the same day, approximately one hour apart.
- Compensation
- Not stated in the trial record.
- Follow-up
- The primary endpoint is measured immediately following the training session, approximately one hour later.

What this trial measures
- Change in Decision Weight for Tastiness vs. Healthiness Attributes in Food ChoiceImmediately prior to and immediately following the training session (pre- and post-assessments, approximately 1 hour apart on the same day)
Food choice will be assessed using a binary choice task in which participants choose between pairs of food items that vary on healthiness, tastiness, savoriness, and overall preference. Choice data will be modeled using mixed-effects logistic regression, with delta-healthiness (difference in healthiness rating between paired items) and delta-tastiness (difference in tastiness rating) entered as predictors of choice. The parameter of interest is the regression coefficient (beta weight) for delta-tastiness relative to delta-healthiness, reflecting the degree to which choice is driven by tastiness versus healthiness attributes. We predict that tastiness beta weight will increase pre- to post-training in patients with AN.
