Morningness-Eveningness and Lifestyle Regularity
Abstract
The relation between morningness (M) - eveningness (E) and lifestyle regularity was studied in a convenience sample of 100 healthy subjects aged between 20 and 59 yrs (47 males and 53 females; mean age 33.6 yrs). Morningness-eveningness was measured by a single administration of the 13-item Composite Scale for Morningness (CSM). Lifestyle regularity was measured by requiring subjects to complete a five-item Social Rhythm Metric diary (SRM-5) each evening for two weeks. Each week of SRM-5 was analyzed separately and the two SRM scores averaged to yield the lifestyle regularity measure for the subject. Subjects were categorized by morningness into top and bottom quartiles of CSM score (denoted M-types and E-types, respectively), with the remaining 50% of subjects denoted as intermediate (I-types). Mean SRM scores significantly differed between the three morningness groups (p <0.001) in the order E-types (SRM = 3.6), then I-types (SRM=4.0), then M-types (SRM=4.9), with higher scores indicating greater daily lifestyle regularity. The effect size of the E-type versus M-type difference was approximately 1.3. The relationship between the CSM and SRM scores was also confirmed using a correlational analysis (rho = 0.428; p < 0.001). This correlational finding was substantially weaker when age was partialed out (r=0.186; p=0.065), although there was still a trend toward a significan relationship. Thus it appears that morning types appear to be more regular in their daily lifestyle than are evening types, suggesting a relationship between these two aspects of human circadian behavior.

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.
