About this study
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Online Educational VideosOther
The videos were developed by the researchers based on a prior study to test if specific information about obesity and weight control influence weight bias.
| Study group | Role | What they receive |
|---|---|---|
| Intervention (I) | Experimental | 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. Receives: Other: Online Educational Videos |
| Weight Control (C1) | Active comparator | 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. Receives: Other: Online Educational Videos |
| Weight Neutral Control (C2) | Placebo comparator | The arm was randomized to a 20 min video about the role dietitians play in society, that made no mention of weight or obesity. Receives: Other: Online Educational Videos |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in "Blame" explicit bias
"Blame" subscore of Anti-fat Attitudes Test, higher score means more bias
Measured: Change from pre to immediately post intervention (1 hour)

Change in "Physical" explicit bias
"Physical" subscore of Anti-fat Attitudes Test, higher score means more bias
