# Regression with Likert Scales

My study

I have seven independent variables (likert scales 1-5) who are skewed to the right. I have one independent variable (likert item 1-5) which is skewed to the left. With SPSS (24) I want to measure what influence the independent variable have on the dependent variable.

I have read multiple articles that discuss the analysis of Likert based data, but can't find a test that fits with my data. I have tried Ordinal Regression, but seeing as I get very high numbers I believe the results are biased. (https://i.sstatic.net/MFkxa.jpg)

Questions

1) Could the problem be that my independent variable are scales and thus have a wide range of answers, because they consist of combined items? And if so, do I have to transform them?

2) Or do I have to tranform the dependent variable, seeing as it is left skewed?

3) Are there other ways to measure regression for Likert scale variable?

Here are two graphs, visualizing my independent and dependent variable: https://i.sstatic.net/8qqHF.jpg

• 'Can't find a test that fits my data' - might be a translation error, but with this I mean that I have read numerous papers on analysis and that I can't find a paper that is applicable to my data. Hence, I am not sure which tests 'fits' my data. 'I get very high numbers' - imgur.com/a/wM6gpqT I have treated my IV as 'Covariates', because there are a lot of answer possiblities.

• I'm not sure what "high numbers" means, but your nagelkerke pseudo r-square is 0.1, so the fit isn't too impressive. Commented Jun 7, 2018 at 21:33
