Giriş: Hasta düşmelerinin önlenebilmesi için ilk olarak hastaların düşme risk faktörlerinin ve bu risk faktörlerine yönelik önleyici girişimlerin belirlenmesi gerekmektedir. Hastaların düşme risk faktörlerinin doğru belirlenebilmesi içinse geçerli ve güvenilir risk değerlendirme aracına ihtiyaç vardır. Amaç: Araştırmanın amacı, İTAKİ Düşme Riski Ölçeği’nin psikometrik özelliklerinin değerlendirilmesidir. Yöntem: Vaka-kontrol metodolojik tasarıma sahip olan araştırma, bir üniversite ve eğitim araştırma hastanesinde gerçekleştirilmiştir. Vaka ve kontrol grubunda yer alan toplam 605 hastanın bilgilerine hastanelerin bilgi işlem birimlerinden ve hasta dosyalarından ulaşılmıştır. İTAKİ Düşme Riski Ölçeği’nin güvenirliği Cronbach alpha katsayısı ve madde toplam puan korelasyonu, geçerliği ise alıcı işlem karakteristiği (ROC eğrisi), duyarlılık, özgüllük, pozitif ön görü değeri ve negatif öngörü değerleri hesaplanarak değerlendirilmiştir. Bulgular: İTAKİ Düşme Riski Ölçeği’nin Cronbach alpha katsayısı .46 olarak hesaplanmıştır. Gerçekleştirilen madde toplam puan korelasyon analizi sonucunda ölçekte yer alan altı maddenin toplam puan ile istatistiksel olarak anlamlı bir korelasyona sahip olmadığı saptanmıştır. İTAKİ Düşme Riski Ölçeği’nin duyarlılık değeri .91, özgüllük değeri .17, pozitif öngörü değeri .36, negatif öngörü değeri ise .78 olarak hesaplanmıştır. ROC analizi sonucunda ROC Eğrisi Altında Kalan Alan .58 olarak hesaplanmıştır (p = .006, %95 Güven Aralığı = .53 - .64). Sonuç: Araştırma kapsamında İTAKİ Düşme Riski Ölçeği’nin güvenirliği ve ayırım gücü düşük saptanmıştır. Sonraki araştırmalarda ölçeğin revize edilerek daha geniş bir örneklemde uygulanması önerilir.

Evaluation of Psychometric Properties of ITAKI Fall Risk Scale

Öz

Background: In order to prevent patient falls, it is first necessary to determine the fall risk factors and preventive interventions for these factors. To determine the fall risk factors of patients correctly, a valid and reliable risk assessment tool is needed. Objectives: The aim of the research is to evaluate the psychometric properties of the ITAKI Fall Risk Scale. Methods: The research is case-control methodologically designed and conducted at a university and educational research hospital. The information of 605 patients in the case and control groups was accessed from the computing software of the hospitals and patient files. The reliability of the scale was evaluated by calculating the Cronbach alpha coefficient and item total score correlation, and validity was evaluated by ROC curve, sensitivity, specificity, positive predictive value and negative foresight values. Results: Cronbach alpha coefficient of the scale was calculated as .46. It was determined that the six items in the scale did not have a statistically significant correlation with the total score. The sensitivity value of the scale was calculated as .91, specificity value .17, positive prediction value .36 and negative prediction value .78. As a result of the ROC analysis, the Under the Area of ROC Curve was calculated as .58 (p = .006, 95% Confidence Intervals = .53 - .64). Conclusion: Reliability and discrimination validity of ITAKI Fall Risk Scale were found low. For future research, it is recommended that the scale is revised and applied in a larger sample.
