How do I compare two questionnaires with Likert Scales

#1
Hi, I am in need of some assistance. I have completed data collection with two questionnaires that are based on Likert scales. One questionnaire has 9 nine groups withscales and the other is one. I have conducted descriptive statistics, completed reversed items and conducted a Cronbach's Alpha test on each group. But I am wanting to find a relationship between the two questionnaires/concepts.
I have been told to do this with a Multiple Linear Regression. But what would be the independent and dependent variable? Would I have to calculate total means for this?
I have also read a possible Spearman's Correlation? But I do not think my data is Linear.
What can I do?
I am doing this all is SPSS.
Many Thanks.
Hannah.
