ABSTRACT
 Objective: The aim of the study is to evaluate the validity and reliability of Turkish version of the Alzheimer's Disease Knowledge Scale (ADKS). Material and Methods: In this methodological study, the data of the study were collected by a questionnaire consisting of socio-demographic information, questions about dementia experience and ADKS Turkish form. The sample of the study is a total of 600 people consisting of university students, adults aged 50 years and over and caregivers of Alzheimer's patient. Results: Participants' ADKS scores ranged from 7 to 26, with an average of 16,17 ± 2,93. Kendall's W coefficient was calculated as 0.79 (p<0.05). ADKS score was found to be higher in the subgroup of caregivers, among people who had family members with dementia, and among caregivers of dementia patients (p<0.05). The difficulty indices of the items are between 0.24 and 0.75; the discrimination indices are above 0.10. The results of reliability analysis showed that the test-retest reliability correlation coefficient was 0.81, the Kuder-Richardson 20 coefficient was 0.74, and the correlations of the items with the total score were above the standard value of 0.20. Conclusion: It was concluded that Turkish version of ADKS was a reliable and valid scale with adequate psychometric properties.

ÖZET
 Amaç: Çalışmanın amacı, Alzheimer Hastalığı Bilgi Ölçeğinin (ADKS) Türkçe geçerlilik ve güvenilirliğini değerlendirmektir. Gereç ve Yöntemler: Metodolojik araştırma olarak planlanan çalışmanın verileri sosyo-demografik bilgiler, demans deneyimi ile ilgili sorular ve ADKS Türkçe formundan oluşan anket ile toplanmıştır. Çalışmanın örneklemi üniversite öğrencileri, 50 yaş ve üzeri yetişkinler ve Alzheimer hastasına bakım verenler alt gruplarından oluşan toplam 600 kişidir. Ölçeğin geçerliliği; kapsam geçerliliği ve yordama geçerliliği ile değerlendirilmiştir. Ölçeğin madde analizleri kapsamında madde güçlük ve madde ayırt edicilik indeksleri hesaplanmıştır. Ölçeğin güvenilirliğini test etmek için test-tekrar test güvenilirliği, iç tutarlılık katsayısı ve düzeltilmiş madde-toplam korelâsyonu katsayıları hesaplanmıştır. Bulgular: Katılımcıların ADKS puanı 7 ile 26 arasında dağılım göstermekte olup ortalaması 16,17±2,93 olarak hesaplanmıştır. Ölçeğin Kendall's W sayısı 0,79 olarak hesaplanmıştır (p<0,05). ADKS ölçek puanının bakım verenler alt grubunda, ailesinde demanslı birey bulunanlarda ve demanslı bireye bakım verenlerde daha yüksek olduğu belirlenmiştir (p<0,05). Ölçekteki maddelerin güçlük indeksleri 0,24 ile 0,75 arasında; ayırt edicilik indeksleri 0,10'un üzerindedir. Ölçeğin üvenilirliğinin değerlendirilmesinde incelenen test-tekrar test güvenilirliği korelasyon katsayısı 0,81, Kuder'Richardson 20 katsayısı 0,74 olarak hesaplanmış, maddelerin toplam puanla korelâsyonları da standart değer 0,20'nin üzerinde belirlenmiştir. Sonuç: ADKS'nin Türkçe versiyonunun yeterli psikometrik özelliklere sahip güvenilir ve geçerli bir ölçek olduğu sonucuna ulaşılmıştır.
