examples of adaptive behavior assessments

Scores on the revised version of this measure, the CTAB-R, are based on a standardization sample that includes four of five regions of the United States (Adams, 2000). 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. There is evidence that the ABI has adequate construct, content, and criterion-related validity, as well as internal reliability, but no data were provided on interrater reliability. The committee's review of the scientific and practice literature also reveals that adaptive behavior is a broadly focused construct. Question Guide for the Assessment of Social-Cognitive Processes. The Vineland-3 is a standardized measure of adaptive behavior-the things that people do to function in their everyday lives. The latter measure requires a more skilled interviewer, as well as a relatively verbal respondent who spontaneously offers sufficient information to permit the interviewer to determine scores on items, or evocation of relevant information through prompts for further details. 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. These data are presented in Chapter 5. This problem, and recommended strategies to avoid errors in diagnosis, are discussed in the section on norms. However, a maladaptive behavior is quite different from adaptive behavior. About three-quarters of children with mild mental retardation had two or more domain scores falling in the marked limitation range, compared with slightly less than one-third of the children without mental retardation (last row). The DSM-IV definition identifies four levels of mental retardation based on IQ: mild, moderate, severe, and profound. Individuals with mental retardation often demonstrate difficulties at the most basic level of recognizing specific types of social cues (e.g., recognizing a person's emotional state on the basis of his or her facial expression) (Adams & Markham, 1991; Gumpel & Wilson, 1996; Harris, 1977; Hobson et al., 1989). SOURCE: Data from Harrison & Oakland (2000b, p. 89). 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. The definition also includes the notion that adaptive skills are affected by the presence of appropriate supports and with appropriate supports over a sustained period, the life functioning of the person with mental retardation will generally improve.. The frequency of performance can be classified along a dimension from never to usually or always. The number of choice points varies by specific instrument or by the variation in the clinical interpretation of the assessor when a formal assessment instrument is not used. This facilitates the early identification of preschool children at risk of mental retardation and permits confirmation of persisting developmental delays. This is usually a parent or teacher. One concern that emerged over time was that it was developed and normed for use with children and youth. 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. As a result, they may become less available for use in disability determinations. This allows the rater to obtain a complete picture of the adaptive functioning of the person being assessed. The CBC differentiates between internalizing (e.g., withdrawal, diminished interests, depressive affect) and externalizing (e.g., aggression against peers or adults, property destruction) behavior problems that may be consistent with a mental disorder (see also Borthwick-Duffy et al., 1997; Fidler et al., 2000; Hodapp et al., 1997). As previously noted, primary concerns in the use of adaptive behavior scales in eligibility determination decisions center on informant bias. Gifted Testing. 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. Dr. Smagula is the 2022 . The standardization sample consisted mostly (80 percent) of adults living in residential facilities, and the overall functioning level of the sample may be lower than if other community-dwelling adults had been included (Harrison, 1998). 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. This test is not administered directly to the child. This nomenclature has dimensions of impairments of body functions, impairments of body structures, activity limitations and participation restrictions, and environmental factors. Under ideal circumstances, adaptive behavior measures should be administered in an examinee's or informant's primary language. 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. In general, the cutoff scores for adaptive behavior should be one standard deviation below the mean in two adaptive behavior areas or one and one-half standard deviations below the mean in one adaptive behavior area. Scales typically include items that permit behavioral assessments for young children and adolescents without disabilities (i.e., superior behavioral development or skill). The Adaptive Behavior Assessment System (ABASHarrison & Oakland, 2000a) is the newest of the adaptive behavior measures that has sound psychometric properties. This assessment utilizes structured observa-tion and/or standardized and nonstandardized tests to determine the levels of . Data from reliability and validity studies of the survey form are very impressive, especially in light of the flexible conversational procedures used for obtaining information. 7-8). In the mastery approach, examinees are encouraged to do their best, and testing conditions are designed to elicit maximum performance. National Research Council (US) Committee on Disability Determination for Mental Retardation; Reschly DJ, Myers TG, Hartel CR, editors. Several other tests have been widely used and have many positive features but do not have the same reputation. The Social Skills Rating Scales (SSRSGresham & Elliott, 1987) is probably the best measure available of social skills adaptation in the school context. Also, English language norms may be lower than the typical performance of a same-age child in another culture. (1999) suggest that this incongruity reflects the problem noted by Clausen (1972) and Zigler et al. The SIB provides norms from infancy to adulthood (40+ years), contains 14 adaptive behavior subscales that fall into four major clusters, and provides an additional full-scale broad independence score. Conversely, adult scales would not need items on school-related behaviors (Kamphaus, 1987a). Purpose of Behavioral Assessment. For example, individuals with very high adaptive performance may be impatient with red tape, resistance to change and organizations that prioritize group harmony over performance. Many adaptive behavior scales contain assessments of problem or maladaptive behavior, but relationships between domains of adaptive and maladaptive behavior are generally low, with correlations tending to be below .25 (and a tendency to be higher in samples of persons with severe or profound retardationHarrison, 1987). Social Skills Dimension of Social Competence. In Chapter 1 we provided the details of SSA's criteria for a disability determination of mental retardation in terms of both mental capacity and adaptive functioning. In addition to summarizing adaptive behavior status for the purposes of diagnosis and establishing SSI and DI eligibility, some adaptive behavior scales, such as the AAMR Adaptive Behavior Scales (both school and residential or community versions) and the Scales of Independent Behavior permit the recording of maladaptive behavior. The instrument must be appropriate to the age of the client and the client's approximate functioning level. The ABS-S:2 is used to identify students who are significantly below their peers in adaptive functioning for diagnostic purposes. At first glance, current definitions seem to be quite similar; however, there are subtle differences in the conceptualization of adaptive behavior that may affect the outcomes of diagnostic decisions for individuals with mental retardation, particularly those in the mild range. In fact, semistructured interviews require the highest level of professional expertise, as the questioning and interpretation of answers requires a high level of training. There is some confusion in the field of developmental disabilities regarding the relationship between problem behavior and adaptive behavior. 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. Doll emerged as a leader in the development of a psychometric measure of adaptive behavior, called social maturity at that time. 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. 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 . Greenspan and Driscoll (1997) proposed a dual nature of competence. They suggest that intelligence, as measured by IQ, is typically viewed as an independent variable that predicts outcomes, whereas personal competence is the combination of what individuals bring to various goals and challenges as well as their relative degree of success in meeting those goals and challenges (p. 130). Similarly, adequate internal consistency of subscales or domains is documented using split-half or alpha coefficients. Some of these scales were developed to serve only one of these purposes; however, several have attempted to include both the breadth required for diagnosis and the depth required for clinical use. Because adaptive behavior scales are typically completed through interview of informants or direct responses (marking of a protocol by the informant), the reliability and the validity of informant responses have been particular concerns. As Switzky et al. A marked limitation is not represented by the number of areas in which social functioning is impaired, but rather by the overall degree of interference in a particular area or combination of areas of functioning. Adams (2000), in contrast, uses a mixture of typical performance with third-party respondents and maximum performance operations. What is adaptive Behaviour assessment? 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. Scores from the instrument that are useful in diagnostic decisions must be provided and, in turn, interpretations need to be guided by the structure and organization of the adaptive behavior inventory. In this fashion, the assessment of social-cognitive processes can become part of a more comprehensive approach to individual assessment that includes information from informants about day-to-day behavior, as well as direct assessment of skills of a social-cognitive nature. For example, some instruments permit more than one respondent to answer different items, depending on which respondent is most knowledgeable about the behavior (Adams, 2000). 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. In such instances, if a same-language or same-culture interviewer is not available, the clinician needs to be very aware of such possible miscommunications in order to obtain a valid interview. Consequently, several features must be balanced. 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. self-care, home living, social skills, self-direction, health and safety, etc.). As with the current Vineland, the content and scales of . In addition, social-cognitive assessment can also be helpful in establishing that an individual's social problems are indeed a manifestation of an underlying cognitive impairment (in accordance with standard definitions of mental retardation), rather than primarily reflecting other factors, such as environmental constraints or motivational characteristics. The skills or abilities items may be readily assessed through direct measures of the individual with behavioral tasks, while performance or does-do features can be assessed only through extensive behavioral observations that often are impractical given the breadth of the adaptive behavior construct and the number of relevant settings. 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 . The ABS-S was standardized on population samples of people with and without mental retardation. Even a statement such as "Emily is aggressive toward her peers" is too vague to target for intervention. The two versions of the AAMR ABS differ with respect to the age groups emphasized and the settings about which items are structured and weighted in item selection. These score patterns also suggest that if a criterion of 1.0 to 1.5 SD was adopted as a cutoff point for each of several limitations in different domains, a much smaller percentage of people would be excluded from eligibility. Presumably, these findings reflect the importance of the schools as a setting in which the presence of mild mental retardation is frequently first identified and the use of adaptive behavior scales as a component of this practice. Administration of adaptive behavior scales generally follows one of two possible formats. Principal Comprehensive Adaptive Behavior Measures and Their Characteristics, Correspondence Between SSI Classification Domains and Domains or Subdomains in Prominent Adaptive Behavior Measures, Percentage of People Ages 5-18 Lower Than Two Standard Deviations Below the Mean on the Domains of the Adaptive Behavior Assessment System, Question Guide for the Assessment of Social-Cognitive Processes, Completion by a professional; or completion by a paraprofessional, with professional supervision (perhaps Class C, not specified), Comprehensive Test of Adaptive Behavior-Revised, -Normative Adaptive Behavior Checklist-Revised (NABC-R) is composed of a subset of CTAB-R items, Completion of NABC-R by a parent or guardian, Completion by a professional; or completion by a paraprofessional, with professional supervision (possibly Class C for & interpretation of scores), Class C; or completion by social worker or educator, Social perception: encoding of social cues. Technical manuals present analyses of data gathered in the process of test development that addresses content validity (in terms of representativeness and inferences from age norms), substantive validity (in that they present either a theoretical or empirically derived model of adaptive behavior to which the scale conforms), generalization validity (with respect to differing age or disability groups), external validity (in terms of concurrence with previous or contemporary adaptive behavior measures and intellectual measures), and consequential validity (in terms of evidence of bias or procedures utilized to reduce bias).
