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 = .

Are self-report measures of adaptive functioning appropriate for those high in psychopathic traits?

There is ongoing debate about the methods that evaluators should use to assess the adaptive functioning of an individual in an Atkins claim, including the appropriateness of using self-report measures and extent to which adaptive functioning measures are valid for persons with a history of violent offending. This study examined whether offenders' self-report adaptive functioning scores tended to decrease as their level of psychopathic traits increased. Eighty-five male felony probationers completed the self-report version of the Adaptive Behavior Assessment System - II (ABAS-II: Harrison & Oakland, 2003), the Psychopathic Personality Inventory - Revised (PPI-R: Lilienfeld & Widows, 2005), and a brief intelligence screening measure.
