Abstract
The goal of our study is to evaluate the decision making and reasoning of the paranoid type schizophrenic patients, and their confidence in reasoning and perseverance in keeping to their decisions via using Reasoning with Inductive Argument Test (RIAT).
Thirty-two delusional patients and 30 healthy volunteers were included in the study. After the diagnostic interview was conducted by SCID-I to the patients who were asked to participate in the study, RIAT test was applied by the interviewer in order to detect the inferential thinking patterns.
Apart for the 3rd item out of 11 RIAT items the difference of initial scores are not statistically significant. After both delusional patient group and control groups’ RIAT items are read, according to ANOVA results of the difference between the belief levels in the result of their initial reasoning and belief level after seeing the alternatives (RIAT belief level before and after), no significant differences were detected for both groups in terms of changes between the belief levels to the RIAT items before and after.
According to this study apart from the area of delusions, it can be say that the reasoning of the patients is normal. Our study indicates that when the delusional patients are compared to the control group in terms of jumping to conclusion and modifying their initial beliefs, they are not different when given similarly sufficient amount of data.

Key words: delusions, reasoning, psychosis, schizophrenia, decision



Paranoid Tip Şizofreniye Sahip Hastalarda Tümevarımsal Akıl Yürütme

Özet
Çalışmamızın amacı paranoid tip şizofreni olan hastaların sağlıklı kontrol grubuyla karar verme, akıl yürütme, akıl yürütmelerine güven dereceleri ve kararlarını sürdürmedeki sebatlarını Tümevarımsal Kanıtlarla Akıl Yürütme Testi (TKAYT) kullanarak değerlendirilmesidir.
Çalışmaya otuz iki delüzyonel hasta ve otuz sağlıklı gönüllü dahil edildi. Araştırmaya çağrılan Hastalara SCID-I ile tanı görüşmesi yapıldıktan sonra inferansiyel düşünme biçimlerini tespit etmek için görüşmeci tarafından TKAYT testi uygulanmıştır.
Delüzyonel bozukluk grubunun ve kontrol grubunun her bir RIAT maddesi ilk inanç düzeyleri arasındaki fark RIAT üçüncü madde dışında istatistiksel olarak anlamsızdı. Delüzyonel bozukluğa sahip hasta grubu ile sağlıklı kontrol grubunun RIAT ifadeleri (maddeleri) okunduktan sonra çıkardıkları ilk sonuca inanma düzeyi ile alternatifleri gördükten sonraki inanma düzeyi (RIAT önce ve sonra inanma düzeyi) arasındaki farkın ANOVA sonuçlarına göre iki grubun önce ve sonra RIAT maddelerine olan inanma düzeyleri açısından oluşan değişimler arasında anlamlı fark saptanmadı (p>0.05).
Çalışmamıza göre delüzyonel alan dışında hastaların karar vermelerinin normal olduğu söylenebilir. Çalışmamız delüzyonel bozukluğa sahip hastaların aynı miktarda veri sunulduğunda ulaştıkları sonuçtaki eminlik düzeyinin sağlıklı kontrollerle benzer olduğunu ve yeni veriler sunulduğunda başlangıç inanç düzeylerinin değişme oranlarının kontrol grubuyla benzer şekilde olduğunu göstermiştir.

Anahtar Kelimeler: delüzyon, akıl yürütme, psikoz, şizofreni, karar verme
