Description
Summary:There is a paucity of empirical studies comparing unidimensional and multidimensional measures of PSM in Sub-Saharan Africa. Data was collected from 350 respondents in 26 Ministries in Ghana and the model was estimated with structural equation modelling. The findings showed that the four-dimensional measure of PSM is not comparable to the unidimensional measure, however, a three-dimensional and unidimensional measure of PSM is comparable. The findings further suggest that there is no significant difference between the three-dimensional and unidimensional measures of PSM in predicting affective commitment and organisational citizenship behaviour. The study contributed to testing the multi-dimensional and uni-dimensional measures of PSM in an African context.
