Test-Retest and Inter-Rater Reliability of the Quebec Adaptive Behavior Scale.
Tasse, Marc J.; And Others
The Quebec Adaptive Behavior Scale (QABS) is widely used in Quebec (Canada) to assess behavior of people with mental retardation in educational, vocational, residential or hospital settings. This study estimated the interrater agreement and test-retest reliability of the QABS. To determine test-retest reliability, the QABS was completed by 27 evaluators for 45 individuals (ages 6 to 47) from group homes, residential facilities, schools, and hospitals. To determine interrater agreement, 44 individuals (ages 3 to 54) were each assessed by two raters. Test-retest reliability coefficients for the global score were .92 between levels of adaptive functioning and .99 between total raw scores. Interrater agreement reliability coefficients for the global score were .83 between levels of adaptive functioning and .99 between total raw scores. The QABS was found to be a highly reliable, norm and criterion-referenced adaptive behavior scale, with clearly written scoring procedures and easy administration. (JDD)
