Turkish adaptation of the Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 with users of prosthetics and orthotics

Abstract

Purpose: Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST-2.0) is a standardized scale which is widely used for assessment of satisfaction of individuals using different types of assistive devices. The aim of this study was to analyze validity and reliability properties of the QUEST in individuals using prosthetics and orthotics in Turkish population.
Methods: One hundred fifty-one individuals, who uses lower extremity orthosis, spinal orthosis, lower extremity or upper extremity prosthesis were included in the study. QUEST was translated into Turkish language and administrated to the participants for two sessions with 7 days interval. Reliability of QUEST was tested with test-retest method (intraclass correlation coefficient-ICC), while internal consistency was analyzed with Cronbach alpha. The validity was assessed using the correlation between the QUEST and Visual analog scale, which measures assistive device and service satisfaction.
Results: Test-retest reliability of the QUEST was found to be perfect (ICC= 0.96, 95% confidence interval: 0.944-0.976). Internal consistency of the QUEST was very good. The Cronbach alpha was found 0.851 for total score, 0.801 for assistive device subscale and 0.835 for service subscale. The high correlations between QUEST and Visual analog scale defined very good validity.
Conclusion: Findings of this study revealed that Turkish QUEST is valid and reliable method and considered to be applicable for assessment of individual satisfaction with assistive device in people using prosthetics and orthotics in Turkish population.

Quebec Yardımcı Teknoloji Kullanıcı Memnuniyeti Değerlendirme 2.0 Anketi’nin protez ve ortez kullanan bireylerde Türkçe adaptasyonu

Abstract

Amaç: Quebec Yardımcı Teknoloji Kullanıcı Memnuniyeti Değerlendirme (Q-YTKMD) anketi, çok çeşitli teknolojik yardımcı cihaz kullanan bireylerin memnuniyetlerinin değerlendirilmesinde yaygın olarak kullanılan, standardize bir ankettir. Bu çalışmanın amacı Türk popülasyonunda protez ve ortez kullanan bireylerde Q-YTKMD anketinin geçerlik ve güvenirlik özelliklerini araştırmak idi.
Yöntem: Çalışmaya çeşitli alt ekstremite ortezi, gövde ortezi ve alt ekstremite veya üst ekstremite protezi kullanan 151 birey dahil edildi. Q-YTKMD anketinin Türkçe çevirisi yapılarak, bireylere 7 gün ara ile 2 kez uygulandı. Anketin güvenirliği test-tekrar test yöntemi (sınıf içi korelasyon katsayısı-ICC) ile değerlendirilirken, iç tutarlılık Cronbach alpha ile analiz edildi. Anketin geçerliği, cihaz ve servis memnuniyetini sorgulayan vizüel analog skalası ile ilişkisine (Pearson korelasyon katsayısı) bakılarak değerlendirildi.
Bulgular: Q-YTKMD-TR anketinin test - tekrar test güvenilirliği mükemmel bulundu (ICC= 0,96, %95 güven aralığı: 0,944-0,976). Anketin iç tutarlık değeri çok iyi olarak tespit edildi. Cronbach alpha katsayısı, anketin toplam skoru için 0,851, yardımcı cihaz memnuniyeti alt başlığı için 0,801 ve hizmet memnuniyeti alt başlığı için 0,835 idi. Q-YTKMD-TR anketi toplam skorunun, vizüel analog skalası gösterdiği yüksek korelasyonlar, anketin çok iyi derecede geçerliliği olduğunu ifade etmekteydi.
Sonuç: Bu çalışmanın sonuçlarına göre Q-YTKMD-TR anketi, protez ve ortez kullanıcılarında, bireylerin yardımcı cihaz memnuniyetini değerlendirmede geçerli ve güvenilir bir yöntem olması ile Türk popülasyonunda uygulanabileceği düşünülmektedir.
