Making comparisons using z-scores

I am trying to examine the degree to which people use different emotion regulation strategies, which includes five different constructs. I operationalized each construct using questions and subscales from different validated measures, which all have different scales. So I need to standardize the scores, and converted the subscale total scores into z-scores. Now I need to compare across the constructs, to see the degree to which people used one emotion regulation strategy over the other. But all my scores are standardized, with a mean of 0 and SD of 1, so how can I make these comparisons while still accomplishing the goal of being able to compare different scales to one another?! Help! :)
