Arm Description

This arm was randomized to a 20 min video that emphasized information about factors other than individual behaviors that influence weight, weight loss and ability to maintain weight. It also indirectly addressed weight bias by explaining how to have conversation about weight and health with a patient with obesity that is free of biases.

This arm was randomized to a 20 min video that emphasized the controllable aspects of weight and gave dietitians an overview of a tool to help plan and monitor weight loss.

The arm was randomized to a 20 min video about the role dietitians play in society, that made no mention of weight or obesity.

5. Study Description

Brief Summary

Weight bias in dietitians is prevalent and may affect patient care. The investigators conducted a randomized controlled trial to test if explicit and implicit bias could be influenced by a short, 20 minute educational video.

Detailed Description

This randomized controlled trial studied the effect of three different videos on weight bias in a nationally representative sample of dietitians. The "intervention" group (I) watched a video about the etiology of obesity, reasons for weight regain, and how to talk to patients about weight. The first "control" group (C1) received information about the role of the environment and individual behavior in weight gain, and tools to help patients control their weight. The second control group (C2) received a weight neutral video about the role of dieticians in society. Bias measures were taken before and just after watching the video, and again one month later.

Masking Description

Participants were told they would be participating in a study that aims to determine the effectiveness of online education in dietitians. They were unaware that determining the effect of the videos on weight bias was the objective of the study.
