The studies were published between 2008 and 2023, in the publication types of thesis, conference paper, and article, in Turkish and English publication languages, and with a cross- sectional study design. The effect of transformational leadership behavior on organizational commitment was examined in a sample of a total of 7.353 health personnel. Egger’s regression method did not test for publication bias (t: 0.92; p: 0.19). The results of the meta-analysis show that transformational leadership behavior has a high- level positive effect on organizational commitment in health institutions (M: 0.41; 95% CI: 0.31-0.49; p<0.001). This result obtained from the study should be supported by studies that will investigate the effect of transformational leadership behavior on organizational commitment according to the types of health personnel."> 0.75; Ʈ>0.19).
