Methods & Materials: The present study is a descriptive comparative causal description. The statistical population included all 18-50 who participated in the survey online. People who completed the questionnaire online were selected for sampling. The research instruments included the circadian inventory rhythms Horne and Ostberg (1976), Petersburg Quality of Sleep Questionnaire (1989), and Alipour et al.’s (2020) Corona-related Anxiety Scale in the Iranian sample. Multivariate analysis of variance (MANOVA) and the Scheffe test were used to analyze the data.
Ethical Considerations: This study was registered with the Ethics Committee Razi University Technology Units Development Center at Institute for Psychoanalytic Studies (No.: 99133).
Results: The results showed that the mean of mental and corona physical anxiety in women and men with evening type is higher than in other classes. Men and women in the evening type have a lower sleep quality than in the morning and middle types. The results also showed significant differences between the types regarding corona anxiety, sleep quality, and sex. The difference between the mean of the morning type and evening types’ mean was more than other differences between the means.
