Evidence of Technical Quality
Populations for which technical quality evidence has been collected No information available in the references reviewed.
Reliability evidence

The internal consistency reliability for individual scales of were in the lower 0.80s.

Test-retest reliability was estimated by having the same parent rate the same students twice (with a lag of 9-70 days).

The test-retest reliability of the composite scores were generally above 0.90.

Inter-rater reliability was estimated by having each child rated by two different parents e (with a lag of 0-70 days between ratings).

The median inter-rater reliability of the composite scores ranged from 0.70 (Tan, 2007).

Validity evidence
Evidence based on content
No information available in the references reviewed.
Evidence based on response processes
No information available in the references reviewed.
Evidence based on internal structure
Factor analysis revealed that the P items had moderate to high loadings on their factors (Tan, 2007).
Evidence based on relations with other variables
Evidence about the validity of BASC came from studies that examined the relationships between BASC scores and scores on other behavior rating scales. Most of the correlations between two scales that measure the same or similar construct were moderate (Tan, 2007).
