ADAPTATION OF HYPERTENSION TREATMENT ADHERENCE SCALE INTO TURKISH, A VALIDITY AND RELIABILITY

Öz

Objective: This study was conducted to adapt the Hypertension Treatment Adherence Scale into Turkish and to assess its validity and reliability. Method: It was conducted using a methodological design with 263 hypertension patients between January 31, 2024 and April 31, 2024. Data were collected using a Patient Information Form, the Hypertension Treatment Adherence Scale, and the Hill-Bone Compliance to High Blood Pressure Therapy Scale. The linguistic validity, content validity, and construct validity of the scale were assessed. Internal consistency was assessed using Cronbach’s alpha reliability coefficient, item-total correlation, split-half method, and time invariance tests. The reliability of the scale was further assessed through test-retest measurements. Statistical significance was accepted as p<0.05. Results: In this study, 58.9% of the patients were women, and 52.9% were primary school graduates. The average duration of hypertension was 10.48±9.06 years and the average duration of medication use was 10.06±8.90 years. The content validity index of the scale was 0.98. In the factor analysis, the Kaiser-Meyer-Olkin value was 0.759, Bartlett’s test of sphericity was χ²=3051.078, p=0.000. In the exploratory factor analysis, the total explained variance was found to be 70.377%. The fit indices obtained from the confirmatory factor analysis indicated that the values were within acceptable and normal ranges, demonstrating a good fit. The Cronbach’s alpha reliability coefficient of the scale was 0.760, while those of the subscales ranged from 0.733 to 0.930. Conclusion: The Hypertension Treatment Adherence Scale was found to be a valid and reliable instrument for assessing treatment adherence among hypertension patients among the Turkish population.

HİPERTANSİYON TEDAVİ UYUM ÖLÇEĞİ’Nİ TÜRKÇEYE UYARLAMA, GEÇERLİK VE GÜVENİRLİK ÇALIŞMASI

Öz

Amaç: Bu araştırma Hipertansiyon Tedavi Uyum Ölçeği’ni Türkçeye uyarlama, geçerlik ve güvenirliğini belirlemek amacıyla yapıldı. Yöntem: Araştırma 31 Ocak 2024-31 Nisan 2024 tarihleri arasında 263 hipertansiyon hastasıyla metodolojik tasarım kullanılarak yapıldı. Veri toplama aşamasında Hasta Bilgi Formu, Hipertansiyon Tedavi Uyum Ölçeği, Hill Bone Hipertansiyon Tedavisine Uyum Ölçeği kullanıldı. Ölçeğin geçerlik çalışmasında dil geçerliği, kapsam geçerliği ve yapı geçerliği incelendi. Ölçeğin yapı geçerliliğini belirlemek için açıklayıcı faktör analizi ve doğrulayıcı faktör analizi yapıldı. İç geçerliliği değerlendirmeye yönelik ise Cronbach alfa güvenirlik katsayısı, madde toplam korelasyonu, yarıya bölme, zaman göre değişmezlik testleri kullanıldı. İstatistiksel anlamlılık p<0.05 kabul edildi. Bulgular: Bu araştırmada hastaların %58.9’u kadın, %52.9’u ilkokul mezunuydu. Hipertansiyon süresi ortalama 10.48±9.06 yıl ve ilaç kullanma süresi ortalama 10.06±8.90 yıldır. Bu ölçeğin kapsam geçerlik indeksi 0.98, faktör analizinde Kaiser-Meyer-Olkin=0.759, Bartlett küresellik testi x2=3051.078, p=0.000, açıklayıcı faktör analizi sonucunda açıklanan varyans 70.377 olarak bulundu. Doğrulayıcı faktör analizine ilişkin bulunan uyum indeksi değerlerinin, normal ve kabul edilebilir değerler arasında olması uyumun iyi olduğunu gösterdi. Ölçeğin Cronbach alfa güvenirlik katsayısı 0.760, alt boyutlarının Cronbach alfa güvenirlik katsayısı ise 0.733 ile 0.930 arasında bulundu. Sonuç: Hipertansiyon Tedavi Uyum Ölçeğinin Türk toplumunda hipertansiyon hastalarının tedaviye uyumunu değerlendirebilmek için geçerli ve güvenilir bir araç olduğu belirlendi.
