ÖZET
 Amaç: Diller Arası Sözcük Bilgisi Testi [Cross-Linguistic Lexical Tasks (CLT)], tek ve çoklu dil bağlamında yaşayan okul öncesi çocukların, isim ve eylemleri anlama ve üretim becerilerini değerlendirmek için tasarlanmıştır. Mevcut araştırma, CLT Türkçe (TR) versiyonunun geçerlik ve güvenirlik ön çalışması niteliğindedir. Bu kapsamda çalışmanın amacı, test maddelerinin uygunluklarının, testin uygulanabilirliğinin incelenmesi ve okul öncesi çocuklara ait CLT-TR ön bulgularının ortaya konmasıdır. Gereç ve Yöntemler: Çalışmanın katılımcıları; Türkçe konuşan tek dilli, tipik gelişim gösteren 120 okul öncesi çocuktur. Katılımcıların yaşları 2, 3, 4 ve 5 şeklinde 4 gruba ayrılmıştır. Madde analizleri kapsamında, CLT-TR madde güçlük ve madde ayırt edicilik değerleri hesaplanmış, katılımcıların alt test puanları yaş grupları arasında ve grup içinde istatistiksel analizlerle karşılaştırılmıştır. Bulgular: Madde analizi sonuçlarına göre testin 128 maddesinden 14'ü kabul edilebilir madde güçlük ve ayırt edicilik değerlerine sahip değildir. Yaş gruplarının CLT-TR alt test puanları, 4-5 yaş grubu dışında bütün yaş grupları arasında anlamlı olarak farklılaşmaktadır. CLT-TR alt testlerinin grup içi karşılaştırmalarında; katılımcılar, üretim alt testlerine kıyasla anlama alt testlerinde; eylemlere kıyasla isimlerde anlamlı derecede daha yüksek puan almışlardır. Sonuç: CLT-TR'nin geçerlik ve güvenirlik çalışması öncesinde bazı test maddelerinin gözden geçirilmesi gerekmektedir. Katılımcıların sözcük bilgisi performansı, anlama alt testlerinde ve isimlerde daha yüksektir. Ön bulgular, testin yapı geçerliğini destekler niteliktedir. Testin, tipik-atipik dil gelişimi gösteren çocuklarda kullanılarak puanlarının karşılaştırması önerilmektedir.

ABSTRACT
 Objective: Cross-Linguistic Lexical Task (CLT) is designed to assess comprehension and production of nouns-verbs in preschool children living in mono/multilingual context. The current research is a preliminary study of CLT Turkish (TR) version. The aim of this study is to examine the quality of test items and to present preliminary findings in measuring lexical knowledge of preschool children. Material and Methods: Participants of the study are 120 typically developing Turkish speaking monolingual preschool children. With item analysis, item difficulty-discrimination indexes are calculated. Participants' scores in CLT-TR subtests are compared between four age groups (2-3-4-5) and within groups. Results: Item analysis results revealed that out of 128, 14 items have low item discrimination and too high item difficulty values. Comparison results show significant difference between the age groups' CLT-TR scores. Younger participants have significantly lower scores than the olders'. There is no significant difference between 4 and 5 years old. Repeated measurements pointed significant differences between subtests within the age groups. Participants' scores are significantly higher in comprehension subtests comparing to production tasks. And they have greater performance in nouns subtests than verbs. Conclusion: Before the validity-reliability study of CLT-TR, some items should be revised. Preschool children's lexical knowledge is greater in comprehension than in production and in nouns than verbs. Preliminary findings are compatible with the theoretical background which can be evidence for the construct validity. It is suggested that CLT-TR can be used to compare preschoolers with and without language disorder.
