The relationship between subordinates' perception of the quality of the leader-member exchange (LMX), organizational commitment (OC), and willingness to engage in organizational citizenship behavior (OCB) was investigated in this pilot study. By surveying direct service staff at a large rehabilitation organization, we examined (a) differences in LMX according to the dyadic gender of the supervisor compared to the employee and dyadic duration of the relationship; and (b) moderation effects of both dyadic duration on the relationship between LMX and OCB and OC, and of dyadic gender on the relationship between LMX and both OCB and OC. The correlation between LMX and OC was significant, r = .38, p = .01. There was evidence of moderating effects of dyadic duration on the relationship between LMX and OCB, F (3.37) = 2.86, P = .05, as well as LMX and DC, F (3. 37) = 6.34, P = .001. There was also evidence that dyadic gender moderates the LMX & OC relationship, F (3. 37) = 5.98, P = .002.
