|Evidence of Technical Quality|
|Populations for which technical quality evidence has been collected||
Evidence has been collected from high school seniors (N=921) enrolled in two large public high schools in the Northeast United States (Galla et al., 2014).
Reliability was assessed by examining correlations in the three subscores across tasks. Coefficients ranged from 0.41 to 0.66. Internal consistency (alpha) was also estimated by treating tasks as items. Coefficients ranged from 0.84 to 0.89. (Galla et al., 2014).
