Obsesif Kompulsif Bozukluğun Kelime Kökü Tamamlama Testi (KKTT) ve Bilişsel Süreçlere Etkisi

Amaç: Bu çalışmada, Obsesif Kompülsif Bozukluğu (OKB) olan bireylerde örtük bellek performansı ile bilişsel süreçlerin ilişkisinin değerlendirilmesi amaçlandı. Materyal ve Metot: Bu çalışma; Yüzüncü Yıl Üniversitesi Tıp Fakültesi Hastanesi Psikiyatri Polikliniğine başvuran; 30 Obsesif Kompülsif Bozukluk (OKB) tanılı hasta ve rastgele seçilen 40 kişilik sağlıklı kontrol grubunda örtük bellek performansı ile bilişsel süreçler değerlendirildi. Her iki grup için; örtük bellek performansını değerlendiren Kelime Kökü Tamamlama Testi (KKTT) ve Sosyo-demografik bilgi formu uygulandı. Hasta grubuna ise bu teste ilave olarak, Yale– Brown Obsesyon Kompulsiyon Ölçeği (Y-BOCS), Boyutsal Yale- Brown Obsesyon Kompulsiyon Ölçeği (DY-BOCS), Obsesyonel İnanışlar Ölçeği (OİÖ), Düşünce Eylem Kaynaşması Ölçeği (TAF) ve Üst Biliş Ölçeği (ÜBÖ) uygulandı. Bulgular: Yapılan değerlendirme neticesinde; Y-BOCS ve bilişsel parametrelerin (TAF-OİÖ-ÜBÖ) puanlarındaki artışın KKTT performansını ters yönde etkilediği saptandı. Ortalama KKTT skoru hasta grubunda 7,63±3,05, kontrol grubunda 6,30±2,09 idi (p=0,034). Örtük bellek performansını en fazla etkileyen bilişsel parametre ise TAF parametresi idi. Sonuç: OKB’da, hastalığın şiddeti arttıkça örtük bellek performansı olumsuz etkilediği saptandı.
