A population approach to the study of emotion: Diurnal rhythms of a working day examined with the day reconstruction method

To date, diurnal rhythms of emotions have been studied with real-time data collection methods mostly in relatively small samples. The Day Reconstruction Method (DRM), a new survey instrument that reconstructs the emotions of a day, is examined as a method for enabling large-scale investigations of rhythms. Diurnal cycles were observed for 12 emotion adjectives in 909 women over a working day. Bimodal patterns with peaks at noon and evenings were detected for positive emotions; peaks in negative emotions were found at mid-morning and mid-afternoon. A V-shaped pattern was found for tired and an inverted U-shaped pattern for competent. Several diurnal patterns from prior studies were replicated. The DRM appears to be a useful tool for the study of emotions. (PsycINFO Database Record (c) 2007 APA, all rights reserved) (from the journal abstract)
