Both identity dimensions fully mediate the link between leadership and citizenship behavior

Evidence

When affective commitment was added to the equation in Step 3, Adj. R2 equaled .37, F(2, 51) = 11.50, p < .001; ΔR2 = .11, F(1, 51) = 9.13, p < .001. The beta weight for transformational leadership was no longer significant when both social categorization and affective commitment were in the equation, suggesting both dimensions of social identity together acted as a full mediator of the effects of transformational leadership on OCB. — Roderick M.
