Abstract
The objective of this study was to investigate the internal structure of the Performance Index in order to
establish the interrelationships between the eight unit performance latent variables. The present study forms
part of a larger study aimed at validating the Leadership Behaviour Inventory (LBI) (Spangenberg & Theron,
2002b) against work unit performance. The validation sample, after imputation of missing values, consisted of
273 cases with observations on all 56 items. Item analysis and dimensionality analysis was performed on each
of the sub-scales using SPSS-windows. Thereafter, confirmatory factor analysis was performed on the reduced
data set using LISREL. The results indicated satisfactory factor loadings on the measurement model. Acceptable
model fit was achieved. Subsequently, the structural model was tested using LISREL. The results provided
statistics of good fit. Only four hypotheses failed to be corroborated in this study. The results are discussed and
suggestions for further research are made.
