Background: The Learning Disability Screening Questionnaire (LDSQ) has been shown to have high sensitivity and specificity to identify those who are likely to meet intellectual disability diagnostic criteria (McKenzie, et al. [McKenzie K., 2015]). However, there is no independent research to date to support these findings. Materials and Methods:…

In Oman and elsewhere in Arab countries school professionals rely on measures that were developed in Western countries. Measures that assess adaptive behaviour (AB) that have been developed in Western cultures are argued to be culturally bound. Nevertheless, these measures are used elsewhere despite a paucity of data that examine their…

The adaptive behavior construct has gained prominent attention in human services over the last several years in Portugal, and its measurement has become an integral part of the assessment of populations with intellectual disability. In Portugal, diagnosis remains exclusively based on IQ measures, although some attention recently has been given to…

A reliability study on the public school version of the American Association on Mental Deficiency Adaptive Behavior Scale (ABS) calculated three different reliability estimates: exact agreeement, kappa, and weighted average. Results demonstrated that while the ABS may be useful in making placement decisions, lack of exact reliability raises…

In a study designed to examine the effects of the difference in method of administration of interrater reliability of the Adaptive Behavior Scale, there were no significant differences in reliability coefficients among informants using three administration methods. Levels of agreement apparently differed with the type of behavior being observed.…

Ratings for 550 mentally retarded adolescents on the American Association of Mental Deficiency Adaptive Behavior Scale (ABS) established the reliability and criterion validity of the ABS and demonstrated sensitivity to variation in behavior between subgroups of mentally retarded students representing differences in seven personal variables…

Mentally retarded adult trainees (N=370) at work preparation centers were rated by their supervisors on the Adaptive Behavior Scale (ABS). Results confirmed the reliability and criterion validity of the ABS, demonstrating its sensitivity to differences in adaptive and maladaptive behavior between subgroups representing variation in seven personal…

The strengths of the scales were concentrated in the areas of domain and construct validity, weaknesses in the areas of discriminant validity, interobserver reliability, and decision-making reliability. (DB)

Potential problems such as scoring errors, interrater reliability, and length of administration in using the Adaptive Behavior Scale to assess functional behavior of severely disabled persons are reviewed, and solutions to the problems are offered. (Author/MC)

Presents and discusses a variety of psychometric information pertaining to the American Association of Mental Deficiency (AAMD) Adaptive Behavior Scale. Presents reliability and validity data. Delineates the technical characteristics of the AAMD Adaptive Behavior Scale. (Author/RC)

With an understanding of the rules of scoring and an appreciation of the need for correctness, the scoring of the Adaptive Behavior Scale, Public School Version, will result in fewer errors. Lacking adequate preparation in scoring, the practitioner should be aware of the potential unreliability of results. (Author)

Evaluations were made of 46 mentally retarded residents (mean age=18.32 years) in a central Ohio state institution using part one of the American Association on Mental Deficiency's Adaptive Behavior Scale. A significant overall setting effect was not revealed in the multivariate analysis of variance for repeated measures. (Author)

The Residential Checklist portion of the Adaptive Functioning Index was evaluated with 218 individuals with mental retardation in a large Australian residential facility, and found to be both valid and reliable for rating the intellectual and behavioral functioning of individuals, despite some inconsistency in the more subjectively rated measures.…

Evaluation of the cumulative files of 143 severely disabled students (ages 6 to 20 years) in five school districts indicated: (1) a lack of appropriate technically adequate norm-referenced tests, (2) technical adequacy not a major determinant in test selection, and (3) less frequent use (than expected) of criterion-referenced and adaptive behavior…

The Adaptive Behavior Scale, as developed, contains 10 domains of behavior reflecting independent functioning and social-emotional responsibility in Part One, and 14 domains of behavior appraising social-emotional adaptation in Part Two. The establishment of construct validity and standardization of the Scale for use with normal and handicapped…
