INTELLIGENCE QUOTIENT (IQ) AND RECEPTIVE-EXPRESSIVE LANGUAGE SKILLS IN 5–6-YEAR-OLD CHILDREN

Öz

Objective: This study examined the association between intelligence quotient (IQ) scores and receptive, expressive, semantic, and grammatical language performance in 5–6-year-old children. Methods: This cross-sectional study prospectively enrolled and assessed 50 children from four cities in Türkiye. IQ was assessed using the Stanford–Binet Intelligence Scale, and language skills were evaluated using the Turkish Early Language Development Test (TEDİL). IQ was treated as a continuous variable, and associations between IQ and language outcomes were examined using Spearman rank correlations. Exploratory sex comparisons used the Mann–Whitney U test. Results: The sample included 25 girls and 25 boys; 37 children were aged 5 years and 13 were aged 6 years. Mean IQ was 110.38±12.72. IQ scores were positively correlated with receptive language (ρ=0.643, p<0.001), expressive language (ρ=0.764, p<0.001), and total language (ρ=0.766, p<0.001). Positive correlations were also observed for all four language subdomains (ρ=0.569–0.726; all p<0.001). Conclusion: Higher IQ scores were associated with stronger receptive, expressive, semantic, and grammatical language performance in this study.

5–6 YAŞ ÇOCUKLARINDA ZEKA BÖLÜMÜ (IQ) VE ALICI-İFADE EDİCİ DİL BECERİLERİ

Öz

Amaç: Bu çalışma, 5–6 yaşındaki çocuklarda zekâ bölümü (IQ) puanları ile alıcı dil, ifade edici dil, anlamsal ve dilbilgisel dil performansı arasındaki ilişkiyi incelemeyi amaçlamıştır. Yöntem: Bu kesitsel çalışmaya Türkiye’nin dört farklı şehrinden 50 çocuk prospektif olarak dahil edilmiş ve değerlendirilmiştir. IQ, Stanford–Binet Zekâ Ölçeği kullanılarak; dil becerileri ise Türkçe Erken Dil Gelişimi Testi (TEDİL) kullanılarak değerlendirilmiştir. IQ sürekli bir değişken olarak ele alınmış ve IQ ile dil sonuçları arasındaki ilişkiler Spearman sıra korelasyon analizi kullanılarak incelenmiştir. Cinsiyete göre yapılan keşifsel karşılaştırmalarda Mann–Whitney U testi kullanılmıştır. Bulgular: Örneklem 25 kız ve 25 erkek çocuktan oluşmuştur; çocukların 37’si 5 yaşında, 13’ü ise 6 yaşındadır. Ortalama IQ puanı 110,38±12,72 olarak bulunmuştur. IQ puanları ile alıcı dil (ρ=0,643, p<0,001), ifade edici dil (ρ=0,764, p<0,001) ve toplam dil (ρ=0,766, p<0,001) arasında pozitif yönde korelasyon saptanmıştır. Dört dil alt alanının tamamında da pozitif korelasyonlar gözlenmiştir (ρ=0,569–0,726; tümü için p<0,001). Sonuç: Bu çalışmada, daha yüksek IQ puanlarının daha güçlü alıcı dil, ifade edici dil, anlamsal ve dilbilgisel dil performansı ile ilişkili olduğu bulunmuştur.
