This study investigated the psychometric properties of a widely-used adaptive functioning measure, the Adaptive Behavior Assessment System- Second Edition, with adults (ABAS-II; Harrison & Oakland, 2003). Participants included 102 adults with ID, ages 18 to 79 years, who resided at a Midwestern developmental center. Test-retest and inter-rater reliability were demonstrated for the ABAS-II General Adaptive Composite (GAC) and domain scores. Additionally, concurrent validity was also demonstrated with the Vineland Adaptive Behavior System- Second Edition (VABS-II) by statistically significant correlations for GAC and domain scores, as well as with the Wechsler Adult Intelligence Scale- Fourth Edition (WAIS-IV) and the Stanford Binet- Fifth Edition (SB-V) IQ scores. Past research indicates that comorbid psychiatric disorders and behavior/emotional symptoms impact the adaptive functioning of individuals with ID differently (Di Nuovo & Buono, 2007; Lopata et al., 2012). Therefore, it seemed likely that individuals displaying behavior or emotional problems/symptoms would weaken the reliability of an informant-rated instrument. Although the ABAS-II test-retest reliability coefficients were not significantly different between two groups (individuals who scored above and below the clinical threshold for comorbid behavioral/emotional problems), inter-rater reliability coefficients for the GAC and Practical domain scores were. These findings can be cautiously extended to the recently published ABAS-3 (Harrison & Oakland, 2015) as there is significant overlap between these two editions. 2016-04-22 English text Xavier University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=xavier1461253948 http://rave.ohiolink.edu/etdc/view?acc_num=xavier1461253948 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
