Abstract
Objective: Delusions are fixed wrong beliefs based on false inference and resistant to change. Most prominent feature of delusions is patients have no insight about their delusional belief. Psychiatry benefits from the scales that evaluate the presence of delusion, the strength of delusion and insight. Out of many scales The Brown Assessment of Beliefs Scale (BABS) is one of the most common scale that used in psychiatry. The aim of our study is to test reliability and validity of BABS’ Turkish version in Turkish population.
Method: BABS is translated from English to Turkish by two clinicians and administered to 30 patients with obsessive compulsive disorder (OCD), and 29 patients with schizophrenia. In order to evaluate inter-rater reliability BABS was administered by two different clinicians. In order to evaluate test- retest reliability, BABS was applied to 57 patients one week later. To examine BABS Turkish discriminant validity we used Beck Cognitive Insight Scale, Schedule for Assesing the Three Components of Insight Scale and insight item of Yale-Brown ObsessiveCompulsive Scale . In order to test construct validity factor analysis was done.
Results: Interrater reliability (Kappa =0.54-0.83) and test–retest reliability (r=0.80-0.96, p<0.001) for the total score and individual item scores was excellent with a high degree of internal consistency (Cronbach alfa=0.90). BABS has strong corelation with Beck Cognitive Insight Scale (r=0.84, p<0.001), Schedule for Assesing the Three Components of Insight Scale (r=0.85, p<0.001) and insight item of Yale-Brown Obsessive Compulsive Scale (r=0.67, p<0.001).
Conclusion: The data attained from the study of reliability and validity of the scale shows that The Brown Assesment of Beliefs Scale supports reliability and validity in Turkish population.

Key words: Insight, reliability, validity
