Türkiye'de Hemşireler için Liderlik Uygulamaları Envanterinin Geçerlilik ve Güvenirliğinin Değerlendirilmesi

Amaç: Bu metodolojik çalışmanın amacı, Türkiye'de hemşireler için Liderlik Uygulamaları Envanteri'nin geçerlilik ve güvenirliğinin değerlendirilmesidir. Yöntem: Araştırmanın örneklemini 97 servis sorumlu hemşiresi (SSH) ve 98 servis hemşiresi oluşturmuştur. Veriler, Liderlik Uygulamaları Envanteri- Öz Değerlendirme ve Gözlemci Değerlendirmesi (Leadership Practices Inventory -LPI) kullanılarak toplanmıştır. Verilerin analizinde Doğrulayıcı Faktör Analizi ve Cronbach Alpha kat sayısı kullanılmıştır. ve toplam üç model sınanmıştır. Modellerin uyum değerlendirilmesinde Ki Kare uyum testi (X2), İyilik Uyum İndeksi (GFI), Ayarlanabilen İyilik Uyum İndeksi (AGFI), Yaklaşık Hata Karaler Ortalamasının Karekökü (RMSEA), Standartize Edilmiş Hataların Ortalama Karelerinin Karekökü (S-RMR), Karşılaştırmalı Uyum İndeksi (CFI) ve Normlaştırılmamış Uyum İndeksi (NNFI) kullanılmıştır. Sonuç: Geliştirilen modellerden üçüncü modelin Ki-kare değerinin (x2= 826.88, p= 0.25) anlamlı olduğu görülmüştür. Uyum indeksi değerleri ise RMSEA= 0.00, NNFI= 0.94, CFI= 1.00, I GFI= 0.89 ve SRMR= 0.052 olarak bulunmuştur. Uyum indeksi değerleri modelin iyi uyum verdiğini göstermektedir. İç tutarlılık incelemesi sonucunda Liderlik Ugulamaları Envanteri'nin Cronbach Alpha kat sayısı lider formu için 0,92, gözlemci için 0.97 bulunmuştur. Öneriler: Bu değerler gözönüne alındığında Liderlik Uygulamaları Envanteri'nin Türkçe formunun, hemşirelerin liderlik uygulamalarını ölçebilecek, yeterli geçerlilik ve güvenilirliğe sahip olduğu bulunmuştur.

Assessing Validity and Reliability of the Leadership Practices Inventory (LPI) for Nurses in Turkey

Aim: The aim of this methodological study was to examine the psychometric properties of the Leadership Practices Inventory (LPI) for nurses in Turkey. Methods: Sample of this study consisted 97 unit charge nurses (UCN) and 98 staff nurses (observers) from two university hospitals. Data were collected through Nurses Data Sheet and LPI-Self and Observer. Confirmatory Factor Analysis and Cronbach alpha coefficients were used to test three alternate models of transformational leadership. c2, Goodness of Fıt Index (GFI), Comparative Fit Index (CFI), Nonnormed Fit Index (NNFI) , Standardized Root Mean Square Residual (SRMR), and Root Mean Square Error of Approximation (RMSEA) were used to evaluate the models. Results: Third model was found to have a good fit when χ2/df ≤ 2.0, fit indices (CFI, NNFI etc) ≥ .95, RMSEA ≤ .06, and SRMR ≤ .08. According to the χ2/df, fit indices, RMSEA, and SRMR values, third model provided better fit than the other models. The internal reliability of the LPI for nurses was 0,92 for leader and 0,97 for observer. Recommendations: When all of these values were taken into account, validity and reliability of the LPI Turkish version was found sufficient to measure nurses' leadership practices.
