*
α for English version was significantly higher than for Spanish version, p <.05.
†
Item correlates more highly with a different composite from one hypothesized. Pairwise correlations conducted with imputed data, n =76,696 for English responses and n =2,344 for Spanish responses.
Boldface is used to denote the diagonal of the item intercorrelation matrix, which lists the correlation between the items and the scale that each item is induced in.
