Üstün Yetenekli Çocuklarda WÇZÖ-R ve WÇZÖ-IV* Zekâ Puanlarının Karşılaştırılması

Wechsler Çocuklar için Zekâ Ölçeği Geliştirilmiş Formu (WÇZÖ-R), üstün yetenekli çocukların belirlenmesinde ya da değerlendirilmesinde yaygın olarak kullanılmaktadır. Ülkemizde, WÇZÖ-R'den sonra Wechsler zekâ ölçeklerinin dördüncü sürümü olan WÇZÖ-IV yakın zamanda kullanılmaya başlanmıştır. Bu açıdan, hem üstün yetenekli çocukları belirlemede WÇZÖ-IV'ün etkililiğini değerlendirmek hem de kullanımda olan WÇZÖ-R ile WÇZÖ-IV arasında ortaya çıkabilecek puan farklarını belirlemek önem kazanmaktadır. Bu çalışmanın amacı, üstün yetenekli çocukların WÇZÖ-R ve WÇZÖ-IV üzerinde elde ettikleri puanları karşılaştırmaktır. Daha önce WÇZÖ-R ile üstün yetenekli olduğu belirlenen 50 çocuğa WÇZÖ-IV uygulanmıştır. Çalışmanın bulguları, WÇZÖ-R Toplam Zekâ Bölümü (ZB) ile WÇZÖ-IV Tüm Ölçek Zekâ Puanı (TÖZP) arasında ve WÇZÖ-R Performans ZB ile WÇZÖ-IV Algısal Akıl Yürütme Puanı (AAYDP) puanları arasında istatistiksel olarak anlamlı fark bulunduğunu göstermektedir. Buna göre, üstün yetenekli çocuklar söz konusu puanlarda, WÇZÖ-R üzerinde daha yüksek puanlar elde etmiştir. Ayrıca, karşılaştırılabilir alt test standart puanları açısından, çocukların WÇZÖ-R üzerinde, Sözcük Dağarcığı alt testi dışında, Benzerlikler, Küplerle Desen ve Şifre alt testlerinden daha yüksek puanlar aldıkları gösterilmiştir. Korelasyon analizleri, her iki sürümden elde edilen puanlar arasında istatistiksel olarak anlamlı ilişkilerin olduğunu ve bu iki sürümün benzer yapıları ölçtüğünü ortaya koymuştur. Değerlendiriciler, WÇZÖ-IV'ü üstün yetenekli çocukları belirlemede kullanırken, eski sürüme göre, bazı alt test standart puanlar ya da dönüştürülmüş puanlar arasında farklılıkların olabileceğini göz önünde bulundurmalıdır.

Comparison of WISC-R and WISC-IV Intelligence Scores in Gifted Children

Wechsler Intelligence Scales for Children-Revised (WISC-R) has been widely used in identifying or assessing gifted children. In our country, WISC-IV, which is the fourth version of Wechsler intelligence scales, will be in use soon. In this respect, it is important to assess both efficiency of WISC-IV in identifying gifted children and to determine the possible score differences between WISC-R and WISC-IV. The purpose of the present study is to compare WISC-R and WISC-IV scores of gifted children. WISC-IV was administered to 50 children who were identified as gifted by WISC-R. The findings of the study showed that there were statistically significant differences between WISC-R Full Scale Intelligence Quotient (FSIQ)/WISC-IV FSIQ and WISC-R Performance IQ/WISC-IV Perceptual Reasoning Index (PRI). Accordingly, gifted children had higher scores on WISC-R than WISC-IV. In terms of comparable subtest scores, they had also higher scores on WISC-R Similarities, Block Design and Coding subtests compared to WISC-IV's same subtests, except for the Vocabulary subtest. The correlation analysis revealed that there were significant relationships between WISC-R and WISC-IV composite and index scores and that both of these versions tested the same constructions. Administering WISC-IV for gifted identification, practitioners should consider some subtest or composite score differences compared to its previous version.
