Mediation remediation

摘要

Theorizing in strategic organization often leads researchers to state hypotheses involving mediating effects, in which an antecedent variable, X, affects an outcome, Y, through the intermediate channel of a mediator, M (Whetten, 1989). Sometimes the entire effect of X on Y is thought to operate through M (i.e. complete mediation), and sometimes X is thought to affect Y directly and also indirectly through M (i.e. partial mediation). When empirical researchers set out to test such mediating hypotheses the vast majority of tests use either of two standard methodologies introduced in the mid-1980s. The first is the 'causal steps' approach of Baron and Kenny (1986), extended in Kenny et al. (1998) and further discussed in MacKinnon et al. (2002) and Shrout and Bolger (2002). The second is the SEM approach, advocated in James and Brett (1984) and further discussed in James et al. (2006).
