Hello everyone,

I conducted an exploratory factor analysis using the maximum likelihood method. In total 20 items were included in the analysis which relate either to work demands or non-work demands. Both the Bartlett test and the KMO criterion provide evidence that factor analysis is appropriate for these data. The correlation matrix of the variables also shows that the individual items are correlated and that clusters form among certain groups of items.

However, the data are not measured on an interval scale therefore polychoric correlations were calculated for both the parallel analysis and the factor analysis itself. Based on the parallel analysis six factors should be extracted.…
