Intervention Video (I), Weight Control Video (C1), Weight Neutral Control Video (C2)
Conditions
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.
Interventions
