Item numbers refer to the numbering used in the field test version of the survey.
Although we received 601 surveys, only 492 contained sufficient data to qualify as an analytic complete.
Shading indicates the correlation for items that were hypothesized to belong to the composite under that column. Item-scale correlations were corrected for item overlap with th total score (ie, item-rest correlations).
