Primary Outcome Measures

Name	Time	Method
<p>BODY SCHEMA<br /><br>The Body Schema task will be used to assess possible disturbances in body<br /><br>schema. De outcome measure of this task is the A/S (aperture to shoulder<br /><br>ratio), which is based on the smallest aperture for which participants rotate<br /><br>their shoulders when they walk through it, and the participants* shoulder<br /><br>width. It will be tested whether AN patients and controls have different A/S<br /><br>values.<br /><br><br /><br>PMT PILOT<br /><br>The PMT pilot contains one main study variable, namely changes in body schema<br /><br>over time (pre vs post assessment). Body schema is assessed with an imagery<br /><br>task in which participants judge whether they would fit through hoops varying<br /><br>in size, while imagining performing this action.<br /><br>We will calculate the critical hoop ratio, based on the smallest hoop for which<br /><br>participants indicated they would fit through at least two out of three trials. </p><br>
