The Turkish Validity and Reliability Study of Female Self-Advocacy in Cancer Survivorship Scale

Year 2024, Volume: 5 Issue: 2, 1 - 21, 30.09.2024

Abstract

Aim: It is important to provide the necessary intervention and support to improve the health and quality of life of women with cancer during the fight against cancer. In this regard, first of all, women with low self-advocacy levels in the fight against cancer should be determined. This study aimed to evaluate the Turkish validity and reliability of the Female Self-Advocacy in Cancer Survivorship (FSACS) Scale, which can be used for this purpose.
Methods: This methodological study was conducted in medical and gynecologic oncology clinics between December 1, 2023 and June 1, 2024. The study included 200 women diagnosed with invasive cancer. The data were collected using the individual information form, the FSACS Scale, the Cancer Empowerment Scale (CES) and the Mental Adjustment to Cancer (MAC) Scale. Scale validity was assessed by language, content, construct, criterion and known group validity methods; scale reliability was evaluated by calculating Cronbach's alpha and McDonald’s omega values. Descriptive statistics were analyzed using frequency analysis, and scale validity and reliability were analyzed using Confirmatory Factor Analysis (CFA), correlation analysis, and mean comparison tests.
Results: The scale's Content Validity Index was 0,78 and content validity was confirmed. According to the CFA results, the scale was categorized under three factors (Being an informed decision maker, Connected strength, and Communicating with my health care providers), and all items had significant factor loadings. The model was validated according to the fit indexes. The Cronbach's alpha and McDonald’s omega values were 0,89 and 0,92, respectively. The scale was high reliable. The corrected item-total correlations of the items were high. Coefficients indicating strong and significant correlations between the FSACS Scale, the CES, the MAC and their subscales provided evidence of criterion validity. The scale successfully determined differences in self-advocacy skills between those with high-low levels of education, with-without metastases, and with-without women gender-specific cancer type.
Conclusion: The Turkish version of the FSACS Scale is a valid and reliable measurement that can be used to assess the self-advocacy of Turkish women with cancer.

Kanserle Mücadelede Kadınların Öz-Savunuculuğu Ölçeği’nin Türkçe Geçerlik ve Güvenirlik Çalışması

Year 2024, Volume: 5 Issue: 2, 1 - 21, 30.09.2024

Abstract

Amaç: Kanser tanısı alan kadınların kanserle mücadele sürecinde sağlığının ve yaşam kalitesinin iyileştirilmesi için gerekli müdahale ve desteğin sağlanması önemlidir. Bu bakımdan öncelikle kanserle mücadelede öz-savunuculuk düzeyi düşük kadınlar belirlenmelidir. Çalışmada bu amaçla kullanılabilecek Kanserle Mücadelede Kadınların Öz-Savunuculuğu Ölçeği (KÖSÖ)’nin Türkçe geçerlik ve güvenirliğinin değerlendirilmesi amaçlanmıştır.
Yöntem: Metodolojik tipteki bu çalışma 1 Aralık 2023 – 1 Haziran 2024 tarihleri aralığında tıbbi onkoloji ve jinekolojik onkoloji kliniklerinde yürütülmüştür. Çalışmaya invaziv kanser tanısı alan 200 kadın katılmıştır. Veriler bireysel bilgi formu, KÖSÖ, Kanser Güçlendirme Ölçeği (KGÖ) ve Kansere Tepki Tarzı Ölçeği (KTTÖ) kullanılarak toplanmıştır. Ölçek geçerliği dil, kapsam, yapı, kriter ve bilinen grup geçerliği yöntemleriyle; ölçek güvenirliği ise Cronbach alfa ve McDonald omega değerlerinin hesaplanmasıyla değerlendirilmiştir. Tanımlayıcı istatistikler frekans analizi, ölçek geçerlik güvenirliği Doğrulayıcı Faktör Analizi (DFA), Pearson korelasyon analizi, ortalama karşılaştırma testleri kullanılarak incelenmiştir.
Bulgular: Ölçeğin Kapsam Geçerlik İndeksi 0,78 olup, kapsam geçerliği sağlanmıştır. DFA sonuçlarına göre ölçek üç faktör (Bilinçli karar verici olma, İlişki kurmanın gücü ve Sağlık çalışanlarıyla iletişim) altında toplanmıştır ve tüm maddelerin anlamlı faktör yüklerine sahip olduğu belirlenmiştir. Ölçeğe ait uyum indekslerine göre model doğrulanmıştır. Ölçeğin Cronbach alfa ve McDonald omega değerleri sırasıyla 0,89 ve 0,92 olup, yüksek güvenirliğe sahip olduğu belirlenmiştir. Ölçek maddelerinin düzeltilmiş madde-toplam korelasyonları yüksek bulunmuştur. KÖSÖ, KGÖ, KTTÖ ve bu ölçeklerin alt boyutları arasında güçlü anlamlı korelasyon olduğunu gösteren katsayılar ölçeğin kriter geçerliğini kanıtlamıştır. Ölçek yüksek-düşük eğitim seviyesine sahip, metastazı olan-olmayan ve kadın cinsiyete özgü kanser türüne sahip olan-olmayanlar arasında öz-savunuculuk becerilerindeki farklılıkları başarılı bir şekilde tespit etmiştir.
Sonuç: KÖSÖ’nün Türkçe versiyonu kanser tanısı alan Türk kadınlarının öz-savunuculuğunun değerlendirilmesinde kullanılabilecek geçerli ve güvenilir bir ölçüm aracıdır."
