†Alternate forms reliability estimated for both the 13-item and 6-item forms.
‡Standard deviation estimates used to compute the aforementioned SEMs were as follows: Ordinal, 13-item form (SD = 10); Dichotomous, 13-item form (SD = 5); Ordinal, 6-item form (SD = 3); Dichotomous, 6-item form (SD = 2), and were drawn from both the literature as well as our current sample.
