How to deal with non-detectable and outlying values in biomarker research: Best practices and recommendations for univariate imputation approaches

Autor: Robert C. Miller, Andreas Walther, Judith Herbers, Lena Schindler, Florian Rupprecht, Wei Gao, Kornelius Schmidt

Publikováno v: Comprehensive psychoneuroendocrinology. 7

Non-detectable (ND) and outlying concentration values (OV) are a common challenge of biomarker investigations. However, best practices on how to aptly deal with the affected cases are still missing. The high methodological heterogeneity in biomarker-

Automating LC-MS/MS mass chromatogram quantification. Wavelet transform based peak detection and automated estimation of peak boundaries and signal-to-noise ratio using signal processing methods

Autor: Kornelius Schmidt, Sören Enge, Robert C. Miller, Florian Rupprecht, Wei Gao

While there are many different methods for peak detection, no automatic methods for marking peak boundaries to calculate area under the curve (AUC) and signal-to-noise ratio (SNR) estimation exist. An algorithm for the automation of liquid chromatogr

Comparison of hair cortisol concentrations between self- and professionally-collected hair samples and the role of five-factor personality traits as potential moderators

Autor: Kornelius Schmidt, Sören Enge, Alexander Hadj-Abo, Robert C. Miller, Felix Butt, Clemens Kirschbaum, Monika Fleischhauer

Publikováno v: Psychoneuroendocrinology

Highlights • HCC of self- and professionally collected hair samples was examined. • A between-subject (N = 482) and a within-subject sample (N = 50) was used. • No significant differences between the two hair collection methods occurred. • Pe

Reconsidering the construct validity of self-reported chronic stress: A multidimensional item response theory approach

Autor: Robert C. Miller, Kornelius Schmidt, Sören Enge

Publikováno v: Psychological assessment. 32(11)

Emerging evidence shows that the construct validity of commonly used chronic stress measures is questionable. Item response theory was used to evaluate the psychometric properties of the Perceived Stress Questionnaire (PSQ), the Perceived Stress Scal

Chronic stress and executive functioning: A specification-curve analysis

Autor: Lisa J. Weckesser, Marcus Möschl, Robert Miller, Kornelius Schmidt, Sören Enge

Publikováno v: Physiology & Behavior. 243:113639

To investigate the association between chronic stress and executive functioning (EF), we assessed 514 young to middle-aged adults in three EF tasks (i.e., Number-Letter, 2-Back, Go/Nogo) that assessed shifting, updating, and inhibition. Chronic stres

Intra-individual stability of hair endocannabinoid and N-acylethanolamine concentrations

Autor: Kornelius Schmidt, Sören Enge, Clemens Kirschbaum, Wei Gao

Publikováno v: Psychoneuroendocrinology. 133:105395

Hair analysis of endocannabinoids and N-acylethanolamines presents a promising methodological advancement for the retrospective assessment of long-term cumulative endocannabinoids and N-acylethanolamines secretion over extended periods of time. A mai

Comparability, stability, and reliability of internet-based mental chronometry in domestic and laboratory settings

Autor: Clemens Kirschbaum, Robert Miller, Kornelius Schmidt, Sören Enge

Publikováno v: Behavior research methods. 50(4)

The internet-based assessment of response time (RT) and error rate (ERR) has recently become a well-validated alternative to traditional laboratory-based assessment, because methodological research has provided evidence for negligible setting- and se
