Evidence of Technical Quality
Populations for which technical quality evidence has been collected

Evidence is based on 700 ratings from adolescents.

Reliability evidence

Internal consistency estimates ranged from 0.75 to 0.88. Test-retest reliability (over a two-to-four-week period) ranged from 0.81 to 0.90. Inter-rater reliability estimates ranged from 0.54 to 0.86.

Validity evidence
Evidence based on content
Intervention-sensitive items were selected using Intervention Item Selection Rules (Meier, 1997). Then, expert clinical judgment was used to identify clusters, revise items, and appraise age-appropriateness.
Evidence based on response processes
No information available in the references reviewed.
Evidence based on internal structure
Confirmatory Factor Analysis was used to support scale scores.
Evidence based on relations with other variables
BIMAS scores showed consistent, positive correlations with scores on similar constructs from the Conners Comprehensive Behavior Rating Scales (CBRSTM; Conners, 2008).
Since only the norm-referenced Standard form is discussed in this chapter, “BIMAS” is used to denote the BIMAS Standard throughout the chapter.
