It is recognized that day forms (morning, moderate, eventide) are related to many of meta-physiologic, cognitive and conductive variables and therefore there is need to Persian questionnaire for measurement of these body preferences. This research was done aimed at surveying psychometric features of morning-eventide questionnaire (Horne and Ostberg, 1976). This study was conducted on 270 students of Allame Tabatabaie University and Tehran University of Science and Researches and four questionnaires of morning-eventide, Beck depression, Oxford happiness, and general health were used for examination of structure validity (convergent, divergent, and factor structure). Considering the correlations achieved between morning-eventide questionnaire and other three questionnaires, and also main questionnaire factor analysis, structure validity of Persian version of this questionnaire was approved. In addition, appropriate Cronbach Alpha Coefficient (-0.79) was achieved. According to suitable statistical analyses and obtained results, it seems that Persian version of morning-eventide questionnaire has appropriate validity and reliability for measurement of day forms and could be effective tools for this.
