Chronotype is defined as individual circadian preference, most often represented on the continuum between two extremes: morningness and eveningness. Growing number of studies show associations between circadian preference and various psychopathological symptoms. Eveningness has been shown to be related with depressiveness in non-clinical population, while mornigness has been presented as protective factor. Schizotypy is a schizophrenic-spectrum personality trait linked with a tendency to eccentricity, magical thinking and unusual experiences. Features of schizotypy has been identified in patients with mood disorders i.e bipolar disorder. While there is growing number of studies evaluating associations between chronotype and affective symptons, to our best knowledge there are no studies adressing the issue of association between schizotypy and circadian preferences. A total of 887 healthy individuals took part in the web-based study. Chronotype has been assessed with the use of Composite Scale of Morningness. Schizotypy has been measured with the use of the enlarged version of The Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE). Analysis revealed significant positive correlations between cognitive disorganization, introvertive/anhedonia, implusiveness/nonconformity and eveningness. To our best knowledge, results indicate for the first time relationship between eveningness and schizotypy, measured by O-LIFE.
