RESUMO
Background and purpose:
Although rumination and schizotypal traits can be considered transdiagnostic phenomena and can occur within non-clinical population as well, a relatively small number of research has been carried out on the topic involving both patient and non clinical participants. The aim of this study is to examine the relationship between schizotypal traits and rumination using a transdiagnostic approach, involving participants living with psychotic disorders and sine morbo individuals.
. Methods:We recruited participants living with psychotic disorders (paranoid schizophrenia, hebephrenia, schizoaffective disorder, etc.) (n = 30) and controls who had not been diagnosed with any mental illnesses (n = 67). The connection between rumination and schizotypal traits was examined by self-report questionnaire method in a cross-sectional arrangement. The Oxford-Liverpool Inventory was used to measure schizotypal traits, and the Ruminative Thought Style Questionnaire was used to determine the level of rumination.
. Results:Schizotypal symptoms (β = 0.575; p < 0.001), especially cognitive disorganization (β = 0.459; p < 0.001) and unusual experiences (β = 0.221; p = 0.029) significantly explained the degree of rumination.
. Conclusion:Our results support the hypothesis that the association between rumination and schizotypic traits is due to decreased cognitive inhibitory functions.
