Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameter in the current study is the error in size estimation of the size of the abdomen before and after providing multisensory input. By subtracting these two scores a difference score emerges. This allows for testing whether size estimation changed from pre to post multisensory input, and whether AN patients and healthy controls differ on this variable. In addition, participants will also estimate the size of control body parts (shoulders, hips, height), we do not expect any differences in size estimation error from pre to post multisensory stimulation. | — |
Secondary
| Measure | Time frame |
|---|---|
| The first secondary study parameter is again the difference in size estimation error from pre to post multisensory stimulation. However, not only group differences will be assessed, we will also investigate whether size estimation errors differ between synchronous and asynchronous multisensory stimulation. Based on our previous study we do not expect differences between providing multisensory input synchronously compared to asynchronously. The second secondary study parameter is the error in size estimation during the follow up measurement. This follow up error can be compared to pre and post size estimation errors. This will indicate whether within either group the change in body size experience after multisensory input is persistent over time. | — |
