Abstract
This paper aimed to identify evidences of validity of the internal structure of the Brazilian version of the multidimensional Leader-Member Exchange scale (LMX-MDM), which was administered to 363 people. Exploratory and confirmatory factorial analysis and correlation analysis with other constructs were performed. The scale presented nine items distributed in three low-order factors grouped into a higher-order LMX factor: Professional Respect (α = 0.93), Affect (α=0.92) and Loyalty (α=0.90), explaining 69.39% of the variance of the phenomenon. Adjustment indicators were satisfactory (χ 2 /g.l=2.20, GFI=0.97, CFI=0.99, RMSEA=0.06). LMX-MDM was positively associated to job satisfaction (r=0.11 to 0.76, p <0.05) and managerial skills (r=0.60 to 0.80, p <0.01), and negatively to turnover intention (r=-0.33 to -0.36, p <0.01). These findings suggest that the LMX-MDM presents evidences of validity for use in measuring quality of the leader-member relationship, which is associated to other organizational phenomena.
