Reliability and Validity of the Turkish Translation of the Delirium Rating Scale- Revised-98

Deliryum Derecelendirme Ölçeği-Revize-98 Türkçe versiyonunun geçerlik ve güvenirliği Amaç: Deliryum yaygın bir nöropsikiyatrik bozukluktur. Deliryum Derecelendirme Ölçeği-Revize-98 (DDÖ-R98), deliryum tanısı ve şiddetinin belirlenmesi için yaygın olarak kullanılan, birçok dile çevrilmiş, iyi derecede geçerli bir ölçektir. Bu çalışmada Deliryum Derecelendirme Ölçeği-Revize-98 Türkçe versiyonunun geçerlik ve güvenirliğini araştırdık.Yöntem: Araştırmaya Konsültasyon liyezon psikiyatri birimine yönlendirilen 30 ardışık deliryum hastası ve kardiyovasküler cerrahi sonrasında rutin olarak takip edilen ve deliryum gelişmeyen 30 hasta alınmıştır. Tüm olguların tanılarını iki psikiyatri uzmanı araştırmacı DSM-IV ölçütlerini kullanarak koymuşlar ve birbirlerinden bağımsız olarak DRS-R-98 ve Standardize Mini Mental Test (SMMT) uygulamışlardır. Tanımlayıcı analizlerin yanında, yapı geçerliliği, ölçek içi faktör analizi, değerlendiriciler arası güvenilirlik, DRS-R-98 ölçeğinin SMMT ile uyumu, iç tutarlılık analizleri ile çeşitli kesme değerleri için özgüllük ve duyarlılık analizleri yapılmıştır.Bulgular: Deliryum ve deliryum gelişmeyen gruplar için sırasıyla katılımcıların yaşları 70.2±15.4 ve 62.8±12.6 (Ort.±SS), DRS-R-98 toplam puanları 25.7±6.3 ve 4.5±2.5 olarak bulunmuştur. Değerlendiriciler arası güvenilirlik için Cronbach ? değeri hem DRS-R-98 toplam hem de şiddet puanları için 0.99 (SVD: 203.74; SVD: 282.98, sırasıyla) olarak saptanmıştır. DRS-R-98-T Şiddet puanları SMMT ile uyumlu bulunmuştur (her iki değerlendirici için r=-0.87, p

Deliryum Derecelendirme Ölçeği–Revize–98 Türkçe versiyonunun geçerlik ve güvenirliği

Reliability and validity of the Turkish translation of the Delirium Rating Scale-Revised-98 Objective: Delirium is a common neuropsychiatric disorder. The Delirium Rating Scale-Revised-98 (DRS-R-98) is a widely used and well-validated delirium diagnostic and severity scale that has been translated into many languages. We investigated the reliability and validity of the Turkish version of the DRS-R-98.Method: Data for 30 consecutive delirium patients were obtained from consultation-liaison psychiatry referrals and 30 non-delirium patients were from routine screening following cardiovascular surgery. Two psychiatrist researchers diagnosed all cases using DSM-IV criteria, and independently administered the DRSR-98 and Mini Mental State Examination (MMSE). Concurrent validity, interrater reliability, inter-battery factor analysis, internal consistency, sensitivity and specificity at various scale cut-off values were analyzed as well as descriptive analyses were performed. Results: Mean age was 70.2±15.4 and 62.8±12.6, and mean DRS-R-98 total score was 25.7±6.3 and 4.5±2.5 for delirium and non-delirium groups, respectively. Cronbachs’ α intraclass coefficients measuring interrater reliability for DRS-R-98 severity and total scale scores were both 0.99 (SVD: 203.74; SVD: 282.98, respectively). DRS-R-98 severity scores were correlated with MMSE (r=-0.87, p
