Correspondence between correctional staff and offender ratings of adaptive behavior

Although several experts have raised concerns about using correctional officers as informants for adaptive behavior assessments, no studies have compared ratings from correctional officers to those from other informants. We compared Adaptive Behavior Assessment System-Second Edition (ABAS-II; Harrison & Oakland, 2003) scores assigned by correctional staff to those assigned by probationers (N = 56) residing in a community corrections facility. Correctional staff assigned markedly lower scores than did probationers on many ABAS-II scales (d = .59 to 1.41 for ABAS-II composite scores). Although none of the probationers qualified for a diagnosis of intellectual disability, 29% received a staff-report ABAS-II composite score that was more than 2 SDs below the normative sample mean, suggesting significant impairment. Correlations between ABAS-II and intelligence measure scores were lower than expected for both types of informants, although they were somewhat stronger for self-report. Lower staff-report scores were associated with higher levels of probationer-reported psychopathology and need for treatment. Overall, these findings highlight limitations of using correctional staff as informants for adaptive behavior assessments. (PsycINFO Database Record
