|Evidence of Technical Quality|
|Populations for which technical quality evidence has been collected||
No information is available in the references reviewed.
Internal consistency reliability coefficients for the overall BSI and composite scores were in the upper 0.80s.
The internal consistency reliability for individual scales of were in the lower 0.80s.
Test-retest reliability was estimated by having the same teacher rate the same students twice (with a lag of 8-65 days).
The test-retest reliability of the composite scores ranged from the middle 0.80s to the low 0.90s.
Inter-rater reliability was estimated by having each child rated by two different teachers (with a lag of 0-62 days between ratings).
The inter-rater reliability of the composite scores ranged from .18 to .82 (Tan, 2007).
