Investigating contingencies: An examination of the impact of span of supervision and upward controllingness on leader–member exchange using traditional and multivariate within- and between-entities analysis.

Using a sample of 150 bank employees, span of supervision and subordinate use of influence tactics were examined as moderators of relationships between leader-member exchange (LMX) and subordinate performance and organizational commitment. Raw score analyses indicate that moderators are present. Span of supervision and upward controlling influence tactics moderate relationships between LMX and both performance and commitment. However, using multiple relationship analysis and multivariate within- and between-entities analysis to assess the level of analysis results in some discrepant findings. These discrepancies are discussed, as are implications for future LMX research.
