Psychosis spectrum disorders (PSD) are chronic mental illnesses that feature positive and negative symptoms, disorganized behavior, and cognitive impairments, often beginning in early life and significantly impacting psychological well-being and functioning (1,2).In addition to these symptoms, patients with PSD show marked cognitive biases, defined as systematic errors in cognitive processing and content in certain situations (3).Consistent evidence indicates a strong association between cognitive bias and psychopathology in PSD (4,5).Cognitive limitations and biases also play an essential role in the formation of delusions and hallucinations (6-8).Cognitive biases do not affect processing capacity; however, cognitive processes are sometimes biased in judgment, leading to distorted perceptions, illogical interpretations, or general irrationality (9,10).Cognitive biases are dysfunctional thinking patterns that lead to incorrect inferences and abnormal perceptions (11).They affect various cognitive domains, including attention, interpretation, decision-making, and memory (12).Several cognitive biases have been linked to delusions and psychosis (4,13).Some cognitive biases observed in PSD include Methods: The sample consisted of 171 patients with PSD and 162 age and sex-matched healthy controls (HC).We investigated I) the factor structure with confirmatory factor analysis (CFA), II) the reliability (internal consistency and test-retest reliability), III) discriminative power, IV) convergent validity, and V) the concurrent validity of DACOBS and CBQp.Results: The 7-factor solution for DACOBS, similar to the original study, and the 5-factor solution for CBQp provided the best fit.DACOBS and CBQp total and their subscale scores showed good internal consistency and test-retest reliability.DACOBS and CBQp total and their subscale scores could differentiate between PSD patients and HCs when controlling for age, sex, and education.DACOBS and CBQp showed a positively moderate correlation.DACOBS and CBQp scores were associated with psychotic symptoms in PSD patients and positive psychic experiences in HCs.Conclusions: Both the DACOBS and the CBQp have good psychometric properties and are suitable instruments for assessing cognitive biases in the Turkish population.The Turkish versions of the DACOBS and CBQp were as reliable and valid as the original.
