Using extensive African American community input, Black researchers developed the Behavioral Assessment for Children of African Heritage (BACAH). Information regarding its strength dimensions is published but not its behavioral and emotional problem scales. Rational (i.e., expert opinion and mathematical) procedures grouped BACAH problem item responses from 1,465 youth, parent, and teacher informants into eight cross-informant scales labeled Anxiety-, Attention/Hyperactive-, Conduct-, Depression-, Hypomania/Mania-, Oppositional-Defiance-, Self-Destructive-, and Reality-Contact-Problems. Data analyses showed no response bias across child gender, socioeconomic status, or age groupings, but bias emerged across informant type, referral status, and rating scale type (i.e., presence and magnitude vs. concern levels regarding problems). Item linking reduced this bias. Items on each BACAH scale discriminate well for problem levels they assess and capably measure children’s problem levels, ranging from moderately below to above the mean. This study’s foundation and findings provide professionals and their test respondents with culturally valid, user friendly, economical, and highly flexible, clinical/research tools to assess Black children’s functioning.
