Meme Kanseri Tedavi Sonuçları Ölçeği Türkçe versiyonunun geçerlik ve güvenirliği

Öz

Amaç: Bu araştırmanın amacı koruyucu meme cerrahisi geçiren hastalarda Meme Kanseri Tedavi Sonuçları Ölçeği (MKTSÖ) Türkçe versiyonunun, geçerlik ve güvenirliğini araştırmaktı.

Yöntem: Çalışmaya, tek taraflı koruyucu meme cerrahisi geçirmiş 50 meme kanseri hastası dahil edildi. Anketin Türkçeye çevrilmesinin ardından güvenirliği ve iç tutarlılığı test edildi. Test-tekrar test güvenirliğini değerlendirmek ve sınıf içi korelasyon katsayısını (ICC) hesaplamak amacıyla anket tüm hastalara iki kez uygulandı. Cronbach alfa değeri anketin iç tutarlılığını belirlemek için hesaplandı. Ölçeğin kriter geçerliğinin belirlenebilmesi için MKTSÖ alt ölçekleri ile Avrupa Kanser Tedavisi ve Araştırmaları Örgütü-Hayat Kalitesi Ölçeği (EORTC-QLQ C30-BR23) alt ölçekleri korelasyonuna bakıldı.

Bulgular: Anketin iç tutarlılığının analizinde, alt ölçekler için Cronbach alfa katsayıları 0,604-0,882 arasında bulundu. Test tekrar test güvenirliği mükemmel (ICC 0,941-1,000 arasında (%95 güven aralığında)) olarak bulundu. MKTSÖ ile EORTC-QLQ C30-BR23 alt ölçekleri arasında orta seviyeden yüksek seviyeye (r=-0,324-r=0,812 aralığında) korelasyon bulundu. En yüksek korelasyon kol semptomları ve MKTSÖ fonksiyonel seviye alt ölçekleri arasında bulundu (r: 0,812). C30 Emosyonel durum ve BR23 seksüel fonskiyon alt ölçekleri ile MKTSÖ’nin hiçbir alt ölçeği arasında korelasyon bulunmadı.

Sonuç: Çalışmanın sonuçları MKTSÖ Türkçe versiyonunun, koruyucu meme cerrahisi geçirmiş hastalarda tedavi sonuçlarını fonksiyonel ve kozmetik açıdan değerlendirmede geçerli ve güvenilir bir ölçüm aracı olduğunu göstermektedir.

Validity and reliability of the Turkish version of the Breast Cancer Treatment Outcome Scale

Öz

Purpose: Aim of this study was to evaluate validity and reliability of Turkish version of the Breast Cancer Treatment Outcome Scale (BCTOS) in patients with conservative breast cancer surgery.

Methods: 50 breast cancer patient who had undergone unilateral conservative breast surgery were included in the study. After the questionnaire was translated into Turkish, the reliability and internal consistency of BCTOS was computed. The questionnaire was applied twice to all patients to evaluate the test-retest reliability and to calculate the “Intraclass Correlation Coefficient” (ICC) value. Cronbach alpha value was calculated to determine the internal consistency of the questionnaire. To determine the criterion validity of the scale; BCTOS subscales and EORTC Quality of Life Questionnaire (EORTC-QLQ C30-BR23) subscales correlation was calculated.

Results: In the analysis of the internal consistency of BCTOS, Cronbach's alpha coefficients was ranged between 0.604-0.882 for the subscales. Test-retest reliability was found to be excellent (ICC between 0.941 to 1,000 (%95 confidence interval)). A moderate to high level (ranges from -0.324 to 0.812) correlation was found between BCTOS and EORTC-QLQ C30-BR23 subscales. The strongest correlation was found between BR23 arm symptoms and BCTOS functional status subscales (r=0.812). No correlations was found between emotional status, sexual function subscales and any subscales of BCTOS.

Conclusion: The results of the study showed that the Turkish version of BCTOS is a valid and reliable measurement tool for evaluating functional and cosmetic treatment outcomes in patients who have undergone conservative breast cancer surgery.
