Abstrakt:	Objective: Catatonia is a common syndrome which can be lifethreatening due to its complications. The aims of the study were to translate the Bush Francis Catatonia Rating Scale (BFCRS) and the KANNER Scale into Turkish, conduct the validity and reliability analyses and to compare the two scales. Method: During the study period extending over 20 consecutive months, the Turkish versions of the scales were administered to 84 patients who were hospitalized in the psychiatry ward or who were admitted to the hospitalization list. The clinical and sociodemographic characteristics of all patients were evaluated. The scales were administered to the patients by two raters, one of whom was permanently involved. Results: Convergent and criterion validities revealed a high correlation between the screening instruments of both scales and between the BFCRS total score and 2nd and 3rd part scores of the KANNER Scale. BFCRS total score of ≥6, KANNER Scale 2nd part score of ≥15, or 3rd part score of ≥1 can be used with high accuracy in diagnosing catatonia according to DSM-5. Internal consistency for both scales was found to be high (Cronbach's alpha 0.902 for BFCRS and 0.9, 0.891, 0.806 for KANNER Scale subsections). Inter-rater reliability was also high for most of the scale items (mean Kappa coefficient: 0.885 for BFCRS and 0.904 for KANNER Scale). Conclusion: In conclusion, the Turkish adaptations of both scales were found to be valid and reliable, showing strong psychometric properties. This study is the first validity and reliability study for the KANNER Scale.
