Items with one or more cross-loadings (i.e., loadings of ≥ 0.30 on components other than the primary/highest loading item)
The “sexual” component is not a true component, as less than three items load on it. It is depicted here primarily to compare our findings with the MENQOL’s subscales as originally conceived.
Note Values represent primary component loadings for each item. Each component is named in quotations for the items of which it is composed. From the physical subscale, items 11, 13, 14, 16, 17, 20, 21, & 26 are not shown here due to loadings on non-extracted components (i.e., components which did not explain a significant amount of variance or did not have ≥ 3 item loadings); Items 18 and 25 are not represented due to absence of loadings on any component.
