Abstract

The cortisol rise after awakening (CAR) is a frequently applied measure of pituitary-adrenal activity. This measure seems to reflect the acrophase of the diurnal cycle and can easily be assessed in saliva samples, collected by the proband or patient under real life conditions. Since different state and trait factors affect the CAR, we here address the questions (a) to which extent state and trait factors affect the CAR, and (b) how often cortisol measures after awakening have to be taken to obtain reliable results. In this study, we assessed the CAR on 6 consecutive days. After applying structural equation models and correlation analyses, we conclude that (a) the CAR of a single day is determined to a great extent by situational factors and only for a small proportion by trait factors and (b) from two (AUC(t)) to six (AUC(i)) days are necessary to achieve reliable trait measures, since state factors bias data from a single day.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
