Comment on van Wijk et?al.

摘要

We were interested to read the paper by van Wijk et al. The authors aimed to assess the reproducibility and validity of a continuous pain-rating procedure resulting to participants having produced reliable mean area under the curve (AUC; van Wijk et al., 2013). These results do not reflect reliability and validity analysis of a test and is a common mistake in reliability analysis (Jeckel et al., 2007; Szklo and Nieto, 2007; Rothman et al., 2008). I found the manuscript title of van Wijk et al. misleading. As the authors point out in their conclusion, a continuous pain registration procedure, using an AUC approach, may be a promising direction to explore.
