Abstract

Risky play is defined as a type of play which includes uncertainty, challenge, excitement, fear and the possibility of physical injury and this type of game allows children to realize their own strengths and weaknesses by testing and pushing their limits. The main purpose of this research was to adapt the Tolerance of Risk in Play Scale (TRiPS), which was originally developed by Hill and Bundy in 2012, into Turkish language and culture, and to test the validity and reliability of the adapted scale using Rasch analysis. Findings related to internal validity, external validity and internal reliability of the original form of the scale were consistent with the adapted scale. Additionally, the item hierarchy that emerged in the original scale development study was similarly observed in the current study. The sample of the study consists of 340 parents, collected via purposive sampling method, whose children enrolled in five different public kindergartens located in Mersin province in Turkey. In conclusion, the findings obtained from the validity and reliability analyzes of the adaptation study of the Tolerance of Risk in Play Scale (TRiPS) into Turkish language and culture show that this scale is a valid and reliable measurement tool to investigate the effect of parents’ risk tolerance on children's risky play.

Oyunda Risk Alma Toleransı Ölçeği’nin (ORAT) Türkçe’ye Uyarlanması: Geçerlik ve Güvenirlik Çalışması

Abstract

Riskli oyun; belirsizlik, mücadele, heyecan, korku ve fiziksel yaralanma olasılığı barındıran ve çocukların kendi güçlü ve zayıf yönlerinin farkına varıp, bu yönlerini test etmelerine ve sınırlarını zorlamalarına fırsat veren bir oyun türü olarak tanımlanmaktadır. Bu araştırmanın temel amacı, 2012 yılında Hill ve Bundy tarafından geliştirilen Oyunda Risk Alma Toleransı Ölçeği’ni (TRiPS) Türkçe’ye uyarlamak ve uyarlanan ölçeğin geçerlilik ve güvenirlik çalışmalarını Rasch analizi ile gerçekleştirmektir. Ölçeğin uyarlanan formuna ilişkin iç geçerlilik, dış geçerlilik ve iç güvenilirlik bulguarı, orijinal ölçek ile tutarlılık göstermiştir. Ayrıca, orijinal ölçek geliştirme çalışmasında ortaya çıkan madde hiyerarşisi, mevcut çalışmada da benzer şekilde bulunmuştur. Araştırmanın örneklemi, Türkiye'de Mersin ilinde yer alan beş farklı devlet anaokuluna kayıtlı çocuğu bulunan 340 ebeveynin, amaçlı örnekleme yöntemi ile seçilmesi ile oluşturulmuştur. Sonuç olarak, Oyunda Risk Alma Toleransı ölçeği (ORAT)’ın Türkçe’ye uyarlama çalışmasına yönelik yapılan geçerlik ve güvenirlik analizlerininden elde edilen bulgular, bu ölçeğin yetişkinlerin risk toleransının çocukların riskli oyunları üzerindeki etkisini araştırmak için geçerli ve güvenilir bir ölçme aracı olduğunu göstermektedir.
