We have trimmed the paper to focus on two of the five elements of sexual subjectivity and anticipated that these two elements would show different results. Thus, we have maintained the separate analyses of these two elements. Please see the added Hypotheses on p. 5-6.
Fourth, each analysis is conducted for each subscale separately, but (with the exception of sexual body-esteem) the scales are consistently (if moderately) intercorrelated. I think it would be informative to test whether associations with age or sexual experience group are operating through a general underlying factor of sexual subjectivity versus are unique to specific facets. The shift to a latent factor approach would have the added benefit of allowing the authors to use FIML to account for missing data at T2, and they could thus use their entire sample.
