Turkish adaptation of the Manager Nurse Research Leadership Scale: Validity and reliability study

This study was conducted to adapt the Nurse Manager Research Leadership Scale into Turkish and introduce it to the nursing literature. The study was conducted between January 2024 and June 2025 with institutional permissions and ethics committee approval. Personal information form and nurse manager research leadership scale were used as data collection tools. The psychometric properties of the scale were tested on 300 nurses working in Duzce province. 71.7% of the nurses participating in the study were female and the average age was 34.28±7.76. 70.76% of the participants stated that they had a bachelor's degree, 53.33% worked in a state hospital, and 34% worked in an intensive care unit. In the adaptation of the scale, translation, expert panel, back-translation and pilot application stages were used. In order to evaluate the validity of the scale, content validity, face validity, item analysis and construct validity were examined. Cronbach alpha, McDonald omega, Spearman-Brown split half and test-retest coefficients were calculated for the reliability analysis of the scale. Findings of the study; As a result of the Exploratory Factor Analysis in the Turkish adaptation of YHALÖ, a one-dimensional model was determined for 15 items in the scale. The single-factor structure obtained in the explanatory factor analysis explains 73.64% of the total variance. As a result of the confirmatory factor analysis, the model was found to be significant (χ²= 109.95, p= 0.075) and it showed a good level of fit with the obtained fit indices (χ²/df= 1.17, CFI=0.99, RMSEA=0.027, SRMR=0.038, RMR= 0.055, NFI= 0.99, NNFI= 0.99, GFI= 0.99, AGFI= 0.99). When the reliability findings of the scale were examined; Cronbach α and McDonald Omega coefficients were found to be 0.97, Spearman-Brown coefficient was found to be 0.94, and test-retest intraclass correlation coefficient was found to be 0.97. These results show that the scale is perfectly reliable. In conclusion; The Turkish adaptation of the Nurse Manager Research Leadership Scale is a valid and reliable scale and can be used to determine the research leadership competencies of nurse managers.
