Measurement equivalence of the Empowerment Scale for White and Black persons with severe mental illness.

Objective: The current study examined the measurement equivalence on a measure of personal empowerment for Black and White consumers of mental health services.

Method: Confirmatory factor analysis was used to assess measurement equivalence of the 28-item Empowerment Scale (Rogers, Chamberlin, Ellison, & Crean, 1997), using data from 1,035 White and 301 Black persons with severe mental illness.

Results: Metric invariance of the Empowerment Scale was supported, in that the factor structure and loadings were equivalent across groups.

Ammons quick test validity among randomly selected referrals.

After selection using a random number table, from volunteer referrals, 89 Youth (61 boys, 28 girls; 48 African Americans, 2 Asian Americans, 27 Euro-Americans, 12 Hispanic Americans), and 147 Adults (107 men, 40 women; 11 African Americans, 6 Asian Americans, 124 Euro-Americans, 6 Hispanic Americans) were administered the Ammons Quick Test (QT). Means, confidence intervals, standard deviations, and Pearson product-moment correlations among tests were computed. The Ammons QT was moderately to strongly and significantly correlated statistically with: the Peabody Picture Vocabulary Test-3b (PPVT-3b); the Vineland Adaptive Behavior Scales-2 Parent/Teacher Form; the Wechsler Intelligence Scale for Children (WISC-4) or the Wechsler Adult Intelligence Scale (WAIS-4); and the Wide Range Achievement Test-Fourth Edition (WRAT-4) Blue and Green Forms.
