Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
<p>The primary endpoint of this study is the effectiveness of the expectation<br /><br>manipulations in affecting sensitivity to pain, itch, and fatigue, i.e. the<br /><br>difference between the conditions in sensitivity to pain, itch, and fatigue<br /><br>after the expectation manipulations, as rated on Visual Analogue Scales (VAS). </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>The secondary endpoints of this study are to explore the effects of the<br /><br>expectation manipulations on autonomic (heart rate, alpha amylase) and<br /><br>endocrine responses (cortisol), as well as to explore the influence of<br /><br>individual characteristics (e.g., general expectations) on the effectiveness of<br /><br>the expectation manipulations.</p><br>
