Abstract:

 Objectıves: The aim of this study was to develop a valid and reliable measurement tool to assess occupational therapy students attitudes and acceptance levels toward 3D printer technology. Materials and Methods: Based on the Technology Acceptance Model, a literature review was conducted and an item pool was created during the scale development process. Items were revised based on expert opinions, and a pilot study was subsequently carried out. A total of 114 occupational therapy students completed a sociodemographic information form and the 3D Printer Acceptance Model Scale. The construct validity of the scale was evaluated using Exploratory Factor Analysis EFA and Confirmatory Factor Analysis CFA; its reliability was assessed using Cronbachs alpha internal consistency coefficient and test-retest analysis. Results: The mean item scores ranged from 1.84 to 4.29. The EFA revealed a three-factor structure. The CFA results indicated a good model fit RMSEA0.052; NNFITLI0.977; CMINDF1.281; CFI0.982. The Cronbachs alpha coefficient was calculated as 0.863, indicating high internal consistency. Significant correlations were found in test-retest analyses for the sub-factors: Perceived Usefulness r0.848; p0.001, Perceived Ease of Use r0.925; p0.001, and Attitude and Intention to Use r0.703; p0.001. Conclusion: The findings indicate that the developed 3D Printer Acceptance Model Scale is a valid and reliable instrument for assessing occupational therapy students attitudes and acceptance levels toward 3D printer technology.

 Amaç: Bu çalışmanın amacı, ergoterapi öğrencilerinin 3 boyutlu yazıcı teknolojisine yönelik tutum ve kabul düzeylerini değerlendirmek için geçerli ve güvenilir bir ölçüm aracı geliştirmektir. Gereç ve Yöntem: Ölçek geliştirme sürecinde Teknoloji Kabul Modeli temel alınarak literatür taraması yapıldı ve madde havuzu oluşturuldu. Uzman görüşleri ile maddeler düzenlendi, ardından pilot uygulama gerçekleştirildi. Çalışmaya katılan 114 ergoterapi öğrencisi sosyodemografik bilgi formu ve 3 Boyutlu Yazıcı Kabul Modeli Ölçeğini tamamlandı. Ölçek yapı geçerliği Açımlayıcı Faktör Analizi AFA ve Doğrulayıcı Faktör Analizi DFA ile; güvenirliğini ise Cronbachs alpha iç-tutarlılık katsayısı ve test-tekrar testi ile değerlendirildi. Bulgular: Ölçek maddelerinin ortalama puan aralığı 1,84-4,29 olarak bulundu. AFA sonucunda ölçeğin üç faktörlü bir yapıya sahip olduğu belirlendi. DFA sonuçları ölçeğin iyi uyum sağladığını gösterdi RMSEA0,052; NNFI TLI0,977; CMINDF1,281; CFI0,982. Cronbachs alpha katsayısı 0,863 olarak bulundu ve ölçeğin yüksek iç tutarlılığa sahip olduğu görüldü. Alt faktörlere ilişkin test-tekrar test analizlerinde anlamlı düzeyde korelasyon saptandı: Algılanan Kullanışlılık r0,848; p0,001, Algılanan Kullanım Kolaylığı r0,925; p0,001 ve Kullanıma Yönelik Tutum ve Niyet r0,703; p0,001. Tartışma: Elde edilen bulgular, geliştirilen 3 Boyutlu Yazıcı Kabul Modeli Ölçeğinin, ergoterapi öğrencilerinin bu teknolojiye yönelik tutum ve kabul düzeylerini ölçmek amacıyla kullanılabilecek geçerli ve güvenilir bir araç olduğunu göstermektedir.
