Diyabetik Ayak Öz-Bakım Davranış Ölçeğinin Tip 2 Diyabetli Hastalarda Yapı Geçerliliği Ve Madde Ayırt Ediciliği

Abstract

Amaç: Bu çalışma, Diyabetik Ayakta Öz Bakım Davranış Ölçeğinin (DAÖD) Türkçe versiyonunun Tip 2 diyabetli hastalarda test edilmesi ve geçerliliğinin sağlanması amacıyla planlanmıştır. Gereç ve Yöntem: Çalışmaya yaşları 53,3±4,7 olan 119 (57 kadın; 62 erkek) Tip-2 diyabetik hasta dahil edilmiştir. DAÖD'ün İngilizce'den Türkçe'ye ileri-geri çevirisi Beaton tarafından belirlenen metodoloji ile yapılmıştır. Katılımcılara DAÖD ile birlikte Dünya Sağlık Örgütü İyilik Hali Ölçeği-22 (İHÖ-22) ve Nottingham Sağlık Profili (NSP) uygulanmıştır. Sonuçlar: Yakınsak yapı geçerlilik analizi için DAÖD puanı ile İHÖ-22 (r=0.639, p<0.001) ve NSP toplam puanı (r=-0.200, p<0.029) arasındaki ilişkiler Pearson korelasyon katsayısı ile hesaplandı. Ayırt edici yapı geçerliği analizi, ölçek puanları açısından kadın ve erkekler arasında fark olmadığını göstermiştir. Açıklayıcı faktör analizi sonuçları, toplam varyansın %75'inin iki faktörle açıklanabileceğini göstermiştir. Doğrulayıcı faktör analizinin de gösterdiği gibi, Türkçe versiyonun faktör yapısı ile orijinal versiyonun faktör yapısı arasındaki uyum yeterli olarak bulunmuştur. Ek olarak, madde ayırt edici güç analizi, tüm maddelerin 'yüksek' ve 'düşük' yanıtları ayırt edebildiğini göstermiştir. Tartışma: DAÖD, diyabet ayak öz-bakım davranışlarını birey merkezli bir yaklaşımla değerlendirebilen ve ölçebilen nadir bir ölçektir. Bu ölçek, diyabetik ayak hastalarında öz-bakım davranışlarını değerlendirmek, müdahale ve eğitim programları planlamak için kullanılabilir.

Construct Validity and Item Discrimination of The Diabetes Foot Self-Care Behavior Scale in Patients with Type-2 Diabetes

Abstract

Background: This study was planned to test the construct validity of the Turkish version of the Diabetes Foot Self-Care Behavior Scale (DFSBS) in patients with type-2 diabetes. Method: 119 type-2 diabetic patients (57 women; 62 men) with a mean age of 53.3±4.7 years were included in this study. The forward-backward translation of the DFSBS was conducted for translation from English to Turkish according to the methodology outlined by Beaton. The World Health Organization Well-being Questionnaire-22 (WBQ-22) and Nottingham Health Profile (NHP) were administered to the participants along with the DFSBS. Results: For convergent construct validity analysis, the correlations between the DFSBS score and WBQ-22 (r=0.639, p<0.001) and NHP total score (r=-0.200, p<0.029) were calculated with the Pearson correlation coefficient. The discriminative construct validity analysis showed that there is no difference between men and women in terms of scale scores. The exploratory factor analysis results showed that 75% of the total variance is explainable by two factors. The fit between the factor structure of the Turkish version and the original version was adequate as shown by the confirmatory factor analysis. Additionally, item discriminative power analysis showed that all items were able to discriminate ‘high’ and ‘low’ responses. Conclusion: The DFSBS is a rare scale that can assess and measure diabetic foot self-care behaviors in a person-centered approach with satisfactory construct validity. This scale can be used to assess self-care behaviors, plan interventions and education programs with diabetic foot clients.
