Development and validation of an organisational justice measurement instrument for a South African context.

Abstract

Measuring organisational justice in a South African context is a concern as the concept is multi-dimensional and there is no comprehensive definition; therefore, an integrative and well-developed measure of organisational justice can advance the measurement and analysis of this concept. This study investigates the development and validity of an organisational justice measuring instrument (OJMI), and determines the relationships between the different dimensions of the concept organisational justice. Data was gathered from 289 participants, employed in a public service organisation. To analyse the data the descriptive and inferential statistics used are Cronbach alpha coefficient, means, the explanatory factor analysis (EFA) and the confirmatory factor analysis (CFA). It was found that the model fitted the data well and the measurement of each dimension, namely strategic direction; distributive, procedural, interactional, informational, diversity management; customer relations; service delivery innovation as well as ethical leadership and management justice were confirmed to be statistically significant and positive. These results indicate that OJMI is a reliable and valid measure that organisations need in order to measure perceptions of fairness, and to monitor trends of fair practices. The validated measuring instrument for organisational justice and the conducted analysis of the interrelationships between the different dimensions of the concept will enable organisations to initiate proactive and reactive interventions to facilitate justice and fair practices.
