Glukoz İzleme Memnuniyet Anketi'nin Türkçe Versiyonunun Geçerlilik ve Güvenilirlik Çalışması

Öz

Amaç: Glukoz İzleme Memnuniyet Anketi, diyabet yönetimini değerlendirmek için önemli bir araçtır, ancak Türk hastalardaki geçerliliği ve güvenilirliği henüz araştırılmamıştır. Bu çalışma, Glukoz İzleme Memnuniyet Anketi’nin Türkçe versiyonunun geçerliliğini ve güvenilirliğini değerlendirmeyi amaçlamaktadır. Gereç ve Yöntem: Bu metodolojik, tanımlayıcı ve korelasyonel çalışma, Ekim 2023 ile Şubat 2024 arasında, Tip 1 Diyabet tanısı almış 220 hasta ile gerçekleştirilmiştir. Çalışma verileri, Anket Formu, Glukoz İzleme Memnuniyet Anketi ve DSÖ-5 İyi Oluş İndeksi kullanılarak çevrimiçi anket tekniği ile toplanmıştır. İstatistiksel analizler IBM SPSS v27 ve IBM SPSS Amos v24 kullanılarak yapılmıştır. Güvenirlik analizlerinde ölçeğin tümü ve dört alt boyutu için Cronbach alfa katsayıları, madde-toplam korelasyonları, “madde silindiğinde Cronbach alfa” değerleri ve Spearman-Brown Split-Half analizi incelenmiştir. Yapı geçerliliği, Doğrulayıcı Faktör Analizi (DFA) ile test edilmiş, varsayımlar kontrol edilmiştir ve maksimum olabilirlik yöntemi kullanılmıştır. Ayrıca, DSÖ-5 İyi Oluş İndeksi ile paralel form güvenirliği değerlendirilmiştir. Bulgular: Madde düzeyindeki içerik geçerliliği indeksleri 0.80 ile 1 arasında değişirken, ölçek düzeyindeki içerik geçerliliği indeksi 0.960 bulunmuştur. Ölçeğin Cronbach alfa katsayısı 0,897, alt boyutlar için ise 0,85 ile 0,90 arasında hesaplanmıştır. Madde-ölçek korelasyonları 0,347 ile 0,719 arasında değişmiştir ve “madde silindiğinde alfa” değerleri 0,85’in üzerinde kalmıştır. Spearman-Brown Split-Half analizinde ölçeğin iki yarısı arasında yüksek düzeyde pozitif yönlü bir korelasyon (0,885) bulunmuştur. DFA, dört faktörlü yapıyı doğrulamış ve uyum indeksleri kabul edilebilir düzeyde bulunmuştur. DSÖ-5 İndeksi ile hem ölçek hem de tüm alt boyutları arasında istatistiksel olarak anlamlı pozitif korelasyonlar gözlemlenmiştir (p<0,001). Sonuç: Bu çalışma, Glukoz İzleme Memnuniyet Anketi’nin, Türk toplumunda Tip 1 Diyabet hastalarında glukoz izleme memnuniyetini ölçmek için geçerli ve güvenilir bir araç olduğunu göstermektedir. Ancak, katılımcıların çoğunluğunu kadınların (%72,7) oluşturması, sonuçların genellenebilirliğini sınırlayabilir. Bu durum, gelecekteki araştırmalarda dikkate alınmalıdır

Validity and Reliability of the Turkish Version of the Glucose Monitoring Satisfaction Survey

Öz

Objective: The Glucose Monitoring Satisfaction Survey (GMSS) is crucial for assessing diabetes management, but its psychometric properties in Turkish patients remain unexplored. This study aimed to evaluate the validity and reliability of the Turkish version of the GMSS. Material and Method: This methodological, descriptive, and correlational study was conducted with 220 patients with type 1 diabetes between October 2023 and February 2024. Data were collected online using a sociodemographic questionnaire, the GMSS, and the WHO-5 Well-Being Index. Statistical analyses were performed with IBM SPSS v27 and IBM SPSS Amos v24. Reliability was evaluated with Cronbach’s alpha coefficients for the overall scale and each subscale, Spearman-Brown Split-Half analysis, item–total correlations, and “Cronbach’s alpha if item deleted.” Validity was examined through language validity, expert-based content validity, and construct validity using Confirmatory Factor Analysis (CFA). Assumptions for CFA were checked, and the maximum likelihood method was applied. Parallel form reliability was also assessed with WHO-5. Results: Item-level content validity indexes ranged between 0.80 and 1.00, while the scale-level index was 0.960. Cronbach’s alpha was 0.897 for the overall scale and ranged between 0.85 and 0.90 across the four subscales. Item–total correlations varied from 0.347 to 0.719, and “alpha if item deleted” values remained above 0.85. The Spearman-Brown Split-Half coefficient was 0.885. CFA supported the four-factor model with acceptable fit indices. Parallel form reliability showed significant positive correlations between the GMSS and WHO-5 (p<0.001). Conclusion: The Turkish version of the GMSS demonstrated strong validity and reliability for assessing satisfaction with glucose monitoring in type 1 diabetes patients. However, the predominance of female participants (72.7%) may limit the generalizability of the findings and should be considered in future research.
