To evaluate the measurement model of the Hungarian reduced Morningness-Eveningness Questionnaire (rMEQ), estimate chronotype prevalence, and examine associations between diurnal preferences and health-impairing behaviors in adolescents.
Surveyed ninth-grade Hungarian high-school students (N = 2565) on diurnal preferences using the rMEQ alongside self-reported smoking, alcohol consumption, and physical inactivity.
Analyzed the data using confirmatory factor analysis (CFA), latent profile analysis (LPA), structural equation modeling (SEM), and analysis of variance (ANOVA).
Confirmatory factor analysis verified a one-factor morningness model encompassing rising time, peak time, retiring time, and self-evaluated chronotype.
Latent profile analysis classified participants into intermediate type (50.7%), morning type (30.5%), and evening type (18.8%).
Morningness correlated with significantly lower risks of smoking, alcohol use, and physical inactivity, whereas evening-type adolescents were significantly more likely to engage in smoking, lifetime alcohol use, and sedentary behavior than intermediate- and morning-type peers.
