Abstract

Aim: The aim of this study is to examine the reliability and validity of the Turkish adaptations of the Positive Beliefs about Rumination Scale (PBRS) and the Negative Beliefs about Rumination Scale (NBRS) in clinical and non-clinical samples. Method: While the non-clinical sample of the study consisted of 455 participants, the clinical sample was composed of 60 major depressive disorder (MDD), 30 panic disorder (PD) and 30 social anxiety disorder (SAD) cases. Results: The results of the factor analyses confirm the construct validity and original factor structure of the scales. Findings obtained from internal consistency and test-retest analyses indicated good reliability for the scales. Supporting the convergent validity of the scales, the correlations between metacognitions about rumination and depressive symptoms, rumination, metacognitions about worry, pathological worry, and anxiety symptoms were found to be positive and significant in the non-clinical sample. Hierarchical regression analyses demonstrated that both scales have predictive validity for depressive symptoms after controlling for anxiety symptoms. As for extreme group comparisons, it supported the criterion-related validity of the scales. In discriminant clinical validity examinations, although both scales were able to differentiate MDD, PD, and SAD groups from healthy controls, they were unable to differentiate the depressive group from the other anxiety disorder groups. Conclusion: A comprehensive psychometric evaluation of the scales demonstrated that both PBRS and NBRS are reliable and valid assessment devices that can be used for research purposes both in clinical and non-clinical groups in Turkey

Özet

Amaç: Bu çalışmanın amacı Ruminasyonla İlgili Olumlu İnanışlar (RUMİ-Olumlu) ve Ruminasyonla İlgili Olumsuz İnanışlar (RUMİ-Olumsuz) ölçeklerinin Türkçe uyarlamasının, klinik ve klinik olmayan örneklemler üzerindeki geçerlik ve güvenilirliğini incelemektir. Yöntem: Araştırmanın klinik olmayan örneklemi 455 katılımcıdan, kli-nik örneklemi 60 majör depresif bozukluk (MDB), 30 panik bozukluk (PB) ve 30 sosyal anksiyete bozukluğu (SAB) vakasından oluşmaktadır.Bulgular: Faktör analizi sonuçları ölçeklerin yapı geçerliğini ve özgün faktör yapılarını doğrulamaktadır. İç tutarlılık ve test-tekrar test ana-lizlerinden elde edilen bulgular ölçeklerin güvenilirliğinin iyi olduğuna işaret etmiştir. Ölçeklerin yakınsak geçerliğini destekler şekilde, klinik olmayan örneklemde ruminasyonla ilgili üstbilişler ile depresif belir-tiler, ruminasyon, endişe ile ilgili üstbilişler, patolojik endişe ve kaygı belirtileri arasındaki korelasyonlar pozitif yönde ve anlamlıdır. Aşamalı regresyon analizlerinden elde edilen bulgular, kaygı belirtileri kontrol edildiğinde, her iki ölçme aracının da depresif belirtileri yordayıcı ge-çerliği olduğunu göstermektedir. Yapılan uç grup karşılaştırmaları ise ölçeklerin ölçüt bağıntılı geçerliğini destekler niteliktedir. Ayırt edici klinik geçerlik incelemelerinde, her iki ölçek de MDB, PB ve SAB grup-larını sağlıklı kontrol grubundan ayırt edebilmiş, buna karşılık depresif grubu diğer kaygı bozuklukları gruplarından ayırt edememiştir. Sonuç: Yapılan kapsamlı psikometrik değerlendirmeler ülkemizde klinik ve klinik olmayan gruplarla yürütülecek araştırmalarda RUMİ-Olumlu ve RUMİ-Olumsuz ölçeklerinin geçerli ve güvenilir birer de-ğerlendirme aracı olarak kullanılabileceğini göstermektedir
