Morningness–eveningness across two student generations : would two decades make a difference?

The majority of morningness-eveningness questionnaires measure differences in preferred time of various daily activities. This study measured differences in actual habits during a 24-hour period by means of the Student Morningness-Eveningness Questionnaire (SMEQ) developed by B. Šverko, S. Vidaček and Lj. Kaliterna (1979). Data on actual daily habits were collected in the 1998 student generation (N = 189) and compared to those of the generation examined in 1977 (N = 128) that were published by Šverko et al. (1979). The aim of the study was to examine psychometric properties of the SMEQ as well as to see if two student generations, 21-year apart, differ in their results on the questionnaire. Cronbach alpha coefficients were identical for both generations (0.77). Discriminant validity of the items has not changed significantly, except in four questions. The results in the SMEQ distributed normally in both generations and no significant differences were found between the mean values of two groups. The results of the study testify to a high stability of the SMEQ as well as to stability of the morningness-eveningness dimension across two generations.
