Objective: Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by impaired social interaction and restrictive/repetitive interests. Autistic traits are similar to symptoms in ASD, but are present at the sub threshold level. Autism Spectrum Questionnaire (AQ) is the only questionnaire that has been translated into Turkish to measure autistic traits. Although populations consisting of university students are used in the studies, the reliability coefficients of AQ in this population are insufficient. The aim of the study is to examine the reliability of AQ in university students.

Material and Methods: Undergraduate and graduate students aged between 18-30 were included in the study. AQ consists of 50 questions in total and is answered in four-point Likert type. In the study, the reliability of the questionnaire was examined by dichotomous scoring, which is the classical approach, and Likert scoring as an alternative. In order to assess reliability, alpha coefficient, Spearman-Brown coefficient, and item-total correlations were analyzed to examine the consistency of items with the total questionnaire.

Results: Seven hundred and sixty participants (438 women, mean age=21.08 years, SD=2.78 range [18-30]) were included in the study. The reliability of the dichotomically scored data were found to be low (α=0.589, rsb=0.580). For Likert scoring, alpha coefficient and Spearman-Brown coefficient were higher but not sufficient (α=0.678, rsb=0.642). Reliability coefficients reached an acceptable level (α=0.789, rsb=0.746) after the removal of 13 items with low coefficients in the item-total correlation analysis.

Conclusion: The study shows that AQ has insufficient validity in university students. An alternative to this is the revised questionnaire AQ-R, which is formed by excluding 13 items. In studies conducted with the participation of university students, AQ-R, which is designed for the target population and has an acceptable reliability level, can be used.

ÜNİVERSİTE ÖĞRENCİLERİNDE OTİZM SPEKTRUM ANKETİ TÜRKÇE FORMUNUN GÜVENİRLİĞİNİN DEĞERLENDİRİLMESİ

Öz

Amaç: Otizm spektrum bozuklukları (OSB) toplumsal etkileşimde bozulma ve buna ek olarak yineleyici hareketlerle karakterize nörogelişimsel bozukluklardır. Otistik özellikler, OSB’li bireylerdeki semptomlara benzer, fakat eşik altı düzeyde görülür. OSB’nin spektrum özelliğine benzer şekilde, otistik özellikler genel popülasyonda dağılım gösterir. Otistik özellikleri ölçmek için Türkçeye kazandırılan tek anket Otizm Spektrum Anketidir (OSA). Çalışmalarda üniversite öğrencilerinden oluşan popülasyonlar kullanılmakla beraber OSA’nın bu popülasyonda güvenirlik katsayıları yetersizdir. Çalışmanın amacı üniversite öğrencilerinde OSA’nın güvenirliğinin incelenmesidir.

Gereç ve Yöntemler: Çalışmaya 18-30 yaş arası lisans ve yüksek lisans öğrencileri dahil edilmiştir. Anket katılımcılara sınıflarda yüz yüze, kâğıt üzerinde uygulanmıştır. OSA, toplam 50 sorudan oluşmaktadır ve dörtlü Likert tipte yanıtlanmaktadır. Çalışmada anketin güvenirliği klasik yaklaşım olan dikotomik puanlama ve buna alternatif olacak şekilde Likert puanlama ile incelenmiştir. Güvenirliğin değerlendirilmesi için alfa katsayısı, Spearman-Brown katsayısı ve maddelerin anketin tümü ile uyumunun irdelenmesi için madde-bütün korelasyonları incelenmiştir.

Bulgular: Yedi yüz altmış katılımcı (438 kadın, ortalama yaş=21,08 yıl, standart sapma [SS]=2,78 aralık [18-30]) çalışmaya dahil olmuştur. Dikotomik olarak puanlanan verilerin güvenirliği düşük bulunmuştur (α=0,589, rsb=0,580). Likert puanlama türünde alfa katsayısı ve Spearman-Brown katsayısı daha yüksek olmakla beraber yeterli değildir (α=0,678, rsb=0,642). Madde-bütün korelasyonu analizinde katsayıları düşük olan 13 maddenin çıkarılması ile güvenirlik katsayılarının kabul edilebilir düzeye ulaşmıştır (α=0,789, rsb=0,746).

Sonuç: Çalışmamızda, üniversite öğrencilerinde OSA’nın güvenirliğinin yetersiz olduğu gösterilmiştir. Buna alternatif olarak 13 maddenin dışlanması ile oluşan revize anket (OSA-R) önerilmiştir. Üniversite öğrencilerinin katılımı ile gerçekleştirilen çalışmalarda hedef popülasyona yönelik olarak düzenlenen ve güvenirliği kabul edilebilir düzeyde olan OSA-R kullanılabilir.
