I have a set of agreement statements designed to measure staff engagement. The data has very low variability between variables (statements) and within respondents. All statements very negatively skewed.  Each statement far from normally distributed. Most claims to be happy with all statements. If i run a factor analysis there is basically one factor with ev gt 1. CFA in Rs lavaan also struggles. I tried a log10 transformation to help the normality issue with little improvement.

I think the underlying issue is that the statements are not "contentious" enough.

What tests are available to analyse non-normal, low variability data?

Or is the only solution to measure issues in such a way as to get more variability and more normal data distributions?

Any comments on "boring" low variability data and poor normality welcome.

Thank you in advance.

Mark
