Table 4-4 presents examples of questions that can guide examiners in eliciting information regarding the three social-cognitive processes reviewed here. Adaptive behavior scales were not among the types of measures (or named measures) that respondents identified as important for the training of future practitioners. Adaptive Behavior Skills Assessment Guide. The adaptive behavior construct has both typical performance and maximum performance elements, a characteristic that complicates measurement operations. Currently available instruments typically do not provide sufficient coverage of some aspects of adaptive functioning for adolescents and adults who are functioning in the IQ range of 60 to 75, the range in which diagnostic decisions about mental retardation are most difficult. However, because several adaptive behavior scales contain maladaptive components, it is worth noting important challenges to reliable measurement. Aggressive could mean that she hits, bites, yells, or displays other forms of aggression. Greenspan (1999) also has argued for many years that the presence of maladaptive behavior, or mental illness, is irrelevant for the purpose of diagnosing of mental retardation. For example, adaptive behavior is defined in terms of effectively coping with common life demands and the ability to meet the standards of personal independence for a particular age group with a specific sociocultural background. Grooming 2. Their work in this area sparked broadened interest in measurement of adaptive behavior among practitioners serving people with mental retardation (Doll, 1927; Kuhlman, 1920; Porteus, 1921; Scheerenberger, 1983). The ABS-S:2 is used to identify students who are significantly below their peers in adaptive functioning for diagnostic purposes. A strength of this scale is that teachers are asked to record when they estimate behaviors, so the resulting threat to reliability and validity can be appraised. The skills needed to make a call today are very different from the skills that were required 20 years ago. In fact, semistructured interviews require the highest level of professional expertise, as the questioning and interpretation of answers requires a high level of training. This allows the rater to obtain a complete picture of the adaptive functioning of the person being assessed. As Switzky et al. The ABI has a normative sample representative of all school-age children, including those with disabilities, and of a sample with mental retardation. However, research that indicates a causal relationship between the childrearing practices of minority families in North America and developmental delay is very limited. National Academies Press (US), Washington (DC). Jane obtained a GAC score of 72. Norms are available to age 18 for the ABES and to age 12 for the parent scale. Adaptive Behavior Below is a listing of some of the adaptive behaviors measured by commonly used scales and checklists based on models of the construct of adaptive behavior. Correspondence Between SSI Classification Domains and Domains or Subdomains in Prominent Adaptive Behavior Measures. Nevertheless, there is merit to the idea of considering these subtle indicators of social competence, i.e., vulnerability, gullibility, and credulity, as important indicators of adaptive behavior in people with mild cognitive impairments. Thus, to the extent that a young adult with mild mental retardation has selected skills that are well developed relative to others, it may not be accurate to describe those skills in developmental terms. For example, assessments are used during classroom instruction to measure students' learning related to the academic content, and different assessments are used to measure students' overall cognitive, physical, or social . Adult norming samples are often included as well, but they tend to consist of people with already identified disabilities. If an appropriate respondent is not available, use of the instrument in some other way (e.g., self-report, unless a self-report version of the protocol is available) violates basic standardization procedures, rendering normative comparisons invalid. The committee therefore, makes two major recommendations to SSA: Recommendation: Standardized adaptive behavior instruments should be used to determine limitations in adaptive functioning. Comprehensive, convenient, and cost-effective, this behavior rating scale . The term concurrently suggests an interdependent relationship in which both constructs are equally important. For example, the SIB-R has four factors (Motor Skills, Social Interaction and Communication Skills, Personal Living Skills, and Community Living Skills) that are combined to yield a Broad Independence score. (1979) concluded from their review of factor analytic studies that adaptive behavior was definitely multidimensional and that the use of a total score would be inappropriate to indicate a general level of adaptation. This chapter has discussed problems with item and score scale floors and ceilings, item sampling in relation to the behaviors that are most problematic at different developmental periods, item density, reliability of informants, and validity of informants. Communication Skills Self-Care Social Skills School/Home Living Community Use Self-Management (includes self-regulation) Personal Health and Safety Functional Academics Leisure The Adaptive Behaviour Assessment System, Third Edition (ABAS-III) is a multidimensional and standardised assessment tool used to assess the functional skills necessary for the daily living of individuals from birth to 89 years of age. The technique of asking open-ended questions that tap the process of generating strategies for solving problems is widely used in standard assessments of intellectual functioning, such as the Wechsler scales. This is usually a parent or teacher. Skills assessed with ABAS-III. Although normed on smaller samples than comprehensive intelligence tests use, current adaptive behavior measures typically have adequate norming samples in relation to both representation of people with and without mental retardation and representation of age groups in the population in relation to the age span of the measure. Assessments work best when they document: (a) quantitative level of performance, (b) fluency of performance (e.g., qualitative criterion performance), (c) the extent to which the individual has failed to acquire skills or failed to perform skills already learned, and (d) the inability of the individual to perform skills through lack of opportunity. Because standard scores and percentile ranks do not indicate standing relative to people without developmental disabilities, and because the norming sample is probably not representative of the population of adults with developmental disabilities, the ABS-RC:2 may not fit the psychometric criteria used in determining a diagnosis of mental retardation according to AAMR requirements (American Association on Mental Retardation, 1992). They also found that it was not the selection of the instrument that determined the number of factors. What is an adaptive score? These concerns are heightened when informants have a stake in the outcome of the assessment (e.g., when responses may affect eligibility for services). Adaptive behavior assessments are often used in preschool and special education programs for determining eligibility, for program planning, and for assessing outcomes. (1) associate current level of functioning with amor activities or settings such as home or playground (2) current and future places where the child might participate are identified (3) identification of substrings in which the child currently participates or may in the future (4) requires an inventory of each subsetting The primary use of adaptive behavior scales in the classification of mental retardation has frequently been confirmatory (i.e., to confirm that a low IQ is associated with delayed acquisition or manifestation of everyday personal and social competencies). Often, there may be no substitute for assistance by a translator familiar with the informant's dialect, even for examiners who are fluent in the informant's primary language. The observational behavioral follow-up assessment (0360T, 0361T) is designed by the physician or other qualied health care professional to identify and evaluate factors that may impede the expression of adaptive behavior. Kamphaus (1987b) reported that the Vineland Adaptive Behavior Scales-Survey Form (Sparrow et al., 1984a) and the Scales of Independent Behavior (Bruininks et al., 1984) had adequate standardization samples. For individuals whose diagnosis is most in question because their measured IQs are near the cutoff, this vital area may determine the presence or absence of mental retardation. In this section, we discuss a variety of psychometric features of adaptive behavior scales that have implications for decision making about mental retardation. Such concerns arise in part because intellectual performance, the other criterion associated with mental retardation, is measured by comprehensive intelligence tests that are the most thoroughly researched forms of psychological assessment (Neisser et al., 1996). A danger of accepting erroneous domains that are not truly distinct from one another (Thompson et al., 1999, p. 17) is that it can lead to the inconsistent application of eligibility criteria and unequal treatment across groups of people. The determination of whether adaptive deficits are marked in character requires clinical interpretation informed in part by the data provided by the scoring of adaptive behavior measures. In the committee's view, the use of standardized measures of adaptive behavior is potentially valuable in the overall assessment of adaptive behavior. The focus is on the ability of the individual to function independently, with minimal external supports, by adjusting his or her behavior in a self-guided fashion to meet varied situational demands and expectations. This means that within any one subscale of an adaptive behavior scale, for example, there may be only one or two items typical of performance for a 10-year-old. However, depending on the age range of adult participants without disabilities sampled during norming studies, the ceiling (i.e., the highest level of behavioral performance assessed) may differ across scales and may affect the characterization of the degree of delay manifested. The residential and community version, ABS-RC:2, was developed to be appropriate for use with persons through 79 years of age. A relatively wide age range must be represented. One particular adaptive behavior scale was ranked 17th in use among 38 scales, but less than 15 percent of respondents reported using this scale frequently. Their repertoires often exclude certain types of socially adaptive strategies. It appears to have good potential for assessing adaptive behavior for diagnostic purposes. Through the assessment of strategy generation, researchers have been able to evaluate an individual's fund of social knowledge (i.e., his or her repertoire of social strategies), as well as the ability to adapt to varied social situations by generating situationally appropriate strategies. One of the key themes throughout the DSM-IV definition is the cultural aspect of adaptive behavior. Professionals voiced early caution about diagnosing mental retardation solely through the use of intelligence testing, especially in the absence of fuller information about the adaptation of the individual. Other scales permit someone to help the person answer questions that cannot be answered without assistance. For the Vineland Adaptive Behavior Scales (Sparrow et al., 1984a) the standardization sample was representative of the U.S. population. For example, a percentile rank of 41 indicates that the examinee scored higher than (or the same as) 41% of the age-matched norm sample. In their review, Thompson et al. The 1983 manual characterized the tasks or activities encompassed by adaptive behavior (and, plausibly social competence) as: During the 1960s, a wider variety of adaptive behavior measures was developed and disseminated (e.g., Allen et al., 1970; Balthazar & English, 1969; Leland et al., 1967). In adolescence and adult life: vocational and social responsibilities. Formal Adaptive Behavior Assessments Assessments are used for many different purposes in the K12 educational setting. Vineland Adaptive Behavior Scales What it measures: How a child's daily living skills compare to those of other kids his age. Doll emerged as a leader in the development of a psychometric measure of adaptive behavior, called social maturity at that time. One must consider not only general competencies across relevant domains but also the level, quality, and fluency of those behaviors. Additional measures of social cognition or social skills and issues relevant to social skills assessment of people with mental retardation have been discussed further (Bell-Dolan & Allan, 1998; Blacher, 1982; Blake & Andrasik, 1986; Jackson et al., 1981; Matson et al., 1983; Meyer et al., 1990; Monti, 1983; Smith & Greenberg, 1979; Van Hasselt et al., 1981). The ABAS-3 combines all-new norms with updated item content to create the leading adaptive skills assessment. Comprehensive adaptive behavior measures are those that assess adaptive behavior through multiple items in multiple domains of functioning. The evaluation is done with the purpose of determining whether a person demonstrates sufficient capacity to function independently . A widely used technique, which was first employed by Spivack and Shure (1974), is to present the individual with a story describing a social problem, as well as a particular strategy that the protagonist might use to resolve the problem. Reprinted with permission. Instead, they differentiate individuals with mental retardation based on the supports they need. In the mastery approach, examinees are encouraged to do their best, and testing conditions are designed to elicit maximum performance. Infants and toddlers may more appropriately be assessed with more specialized measures in most cases. In fact, only one adaptive behavior test manual provides data that would be useful for answering this question. Additional examples of adaptive skills include getting dressed, bathing, cleaning and completing chores, socializing with others, and managing finances. It also allows for reconciliation of ratings among these informants. The other consists of a person who also knows the individual being assessed well but who independently completes a checklist of specific items without assistance. This important finding has direct implications for definitions that require limitations to be observed in a specific number of areas. The VABS-3 assesses three domains of adaptive behaviors: communication, daily living, and socialization, with an additional optional motor skills assessment. It would be difficult to set up situations in which individuals can demonstrate their ability to perform a wide variety of social, communicative, and daily living behaviors. In order to make reliable and valid judgments about the presence or absence of many behaviors, the items may need such extensive clarification as to obscure the meaning of such behaviors for many respondents. In addition, there is a strong need to fund studies examining the nature and distribution of adaptive behavior deficits among individuals with mental retardation in general and those with mild mental retardation more specifically. Average reliability coefficients of the adaptive skill areas across age groups range from .86 to .97, with the majority above .90 and corrected reliability coefficients of individuals with clinical diagnoses above .98. The assessment of adaptive behavior became a formal part of the diagnostic nomenclature for mental retardation with the publication of the 1959 manual of the American Association of Mental Deficiency (Heber, 1959, distributed in 1961). Percentage of People Ages 5-18 Lower Than Two Standard Deviations Below the Mean on the Domains of the Adaptive Behavior Assessment System. Several other tests have been widely used and have many positive features but do not have the same reputation. There are vast differences in how the third-party respondent reports on the adaptive behaviors of a client, particularly in the structure for the interview. Does the person recognize that a social problem has occurred? As a result, the committee commissioned Monte Carlo simulations to understand better the implications of requiring a specific numeric cutoff point. As environments change, people must learn new skills in order continue to meet the environmental demands. These include clinical assessment by interview methods (unstructured, structured, semistructured, direct observation), usually with the aid of clinical instruments that are completed by the evaluator during the interview, and the use of checklists that are completed either by an observer or by the individual being assessed.

A record of maladaptive behavior may permit an individual to be qualified for SSI by virtue of concurrent IQ in the range of 2 to 2.66 SD and presence of another mental (or behavioral) disorder (Jacobson, 1990; Jacobson & Janicki, 1983). The available instruments include indirect assessments, such as rating scales that assess an individual's typical performance of social behaviors based on information from informants, including teachers, parents, and job coaches, as well as instruments that permit direct assessment of the processes that, according to theoretical models of successful social adaptation, underlie the ability to perform situationally appropriate behavior. These procedures, however, need to be employed using an instrument that is reliable, has valid criteria for evaluating adaptive behavior, and uses empirically based norms. Also, current measures also evidence strong validity, as described in the chapter. The implicit rationale for not providing any statistical criteria for adaptive behavior testing is based on the existing limitations in instruments that measure adaptive behavior, specifically in terms of the comprehensiveness of measuring all domains and the reliability of measuring individual domains. Edger Doll produced form board speeded performance tests, which were analogues to everyday vocational tasks. This facilitates the early identification of preschool children at risk of mental retardation and permits confirmation of persisting developmental delays. self-care, home living, social skills, self-direction, health and safety, etc.). Interpretation should focus on the composite score or, perhaps, implement the AAMR classification criterion of deficits in two or more adaptive skills areas. Conversely, adult scales would not need items on school-related behaviors (Kamphaus, 1987a). There is no mention of any standardized cutoffs for adaptive ability, except for mention of the use of scales of social maturity and adaptation in the measurement of adaptive behavior. Purpose of Behavioral Assessment. Because adaptive behavior scales are targeted either specifically at children and adolescents or at groups ranging from children to young adults, there is a strong developmental component to their structures (Widaman et al., 1987). Traditional measures of achievement and intellectual functioning are examples of maximum performance tests. In the recent Manual of Diagnosis and Professional Practice in Mental Retardation (Jacobson & Mulick, 1996), Division 33 of the American Psychological Association put forth a definition of mental retardation that emphasizes significant limitations in intellectual functioning and adaptive behavior. . assessment of Jane's adaptive behavior. Furthermore, these limitations may be more noticeable in certain settings or circumstances than in others (Greenspan, 1999). The Adaptive Behavior Evaluation Scale (ABESMcCarney, 1983) and the Parent Rating of Student Behavior (PRSBMcCarney, 1988) are used to identify mental retardation, learning disabilities, behavior disorders, vision or hearing impairments, and physical disabilities in students ages 5 to 21.
