What is LMX theory?

Many earlier leadership theories assumed a leader uses one style with the whole group. Leader-member exchange (LMX) theory instead takes each leader-follower dyad as the unit of analysis.

Development

  1. Vertical dyad linkage (VDL; Dansereau, Graen & Haga, 1975): leaders formed high-trust, high-latitude relationships with some members (in-group) and contract-level relationships with others (out-group).
  2. LMX and outcomes: higher-quality relationships were linked to better performance, satisfaction and commitment and lower turnover.
  3. Leadership making (Graen & Uhl-Bien, 1995): leaders should build high-quality relationships with all members through three phases, stranger, acquaintance and mature partnership.

In-group vs out-group

In-group (high LMX)Out-group (low LMX)
BasisTrust, respect, mutual obligationEmployment contract, formal role
Leader providesInformation, latitude, support, opportunitiesPrescribed support
Member providesExtra effort, responsibilityEffort within the job description

Measurement

The most common instrument is the seven-item LMX-7 (Graen & Uhl-Bien, 1995). Meta-analyses (Gerstner & Day, 1997; Dulebohn et al., 2012) report positive links with performance, satisfaction and commitment and a negative link with turnover intentions.

Criticism

  • In-group/out-group differentiation can look unfair or like favoritism.
  • How relationship quality develops is under-specified.
  • There is debate over unidimensional versus multidimensional measures (LMX-MDM).
