We have a data set from N=193 participants. They assessed Corporate Image, Employer Image, Customer Experience and Employer Attractiveness (on Likert scales) for 8 different companies (each of the participants assessed all 8 companies). Employer Attractiveness is the DV. We ran regression for the total of 193*8 = 1544 observations to identify which of the IDVs (Corporate Image, Employer Image, Customer Satisfaction) has the largest impact on Employer Attractiveness (which is our research question). Now feedback of reviewers is mixed and irritating. One says, we must run a SEM in order to discern impact strength of the IDVs. Another says, we should apply a repeated-measures/within-subjects design. Can anybody help?
