An Analysis of Relationships Among Transformational Leadership, Organisational Culture and Organisational Success Using SEM for Three Public Hospitals in Turkey

The aim study is to analyse using structural equation modelling (SEM) the impacts of transformational leadership (TFL) and organisational culture (OC) on organisational success (OS) from the hospital employees’ perspective, using SEM. Furthermore, we would like to investigate the mediating role of OC between TFL and OS. This study is a cross-sectional analytical study. Research data were collected by questionnaires from 304 hospital employees. Descriptive statistics, Pearson correlation analysis, confirmatory factor analysis and SEM were calculated using R Studio with lavaan and SemPlot packages. TFL was positively correlated with OS ( r = 0.514, p < .01), OC ( r = 0.408; p < .01) and education ( r = 0.177; p < .01). In effect on the OS model, TFL positively and significantly affected OS ( β = 0.311; p < .01) and OC ( β = 0.644; p < .001). TFL had an indirect effect on OS by the mediator role of OC ( β = 0.244; p < .05). Positive relationships were found between TFL, OC and OS. TFL had a significant direct effect on OS. TFL had an indirect effect on OS by the mediator role of OC. Although the direct effect was larger than the mediation effect, the mediation effect of OC is significant.
