The result is an overidentification of skill limitations among minority children. Performance on tasks taken from the current program 3. The Adaptive Behavior Assessment System (ABAS-2) is a behavior rating scale that gives a complete assessment of adaptive skills across the lifespan (Harrison & Oakland, 2000). If not, diagnosticians would have to consider a profile of adaptive behavior deficits that takes all domain scores into account. Another psychometric concern is whether the norming samples are adequate. Brown, personal correspondence, June 17, 2001). Research with individuals with mental retardation has consistently documented limitations in their performance of both of these components of strategy generation. Stinnett (1997) matched ABS items to the 10 adaptive skill areas in the AAMR definition and found that some skill areas are addressed in depth by the ABS (social skills and self-care domains), while others have too few items to give reliable estimates (home living, health and safety, leisure). Some of the more common and relevant response sets are (a) social desirability, involving responses consistent with positive or desirable connotations of the items or behaviors, (b) acquiescence, involving the tendency to say yes, true, or, in cases in which knowledge is lacking or uncertain, sometimes, and (c) halo effects, involving reporting higher adaptive behavior among persons who are more liked by the respondent. National Academies Press (US), Washington (DC). "A system of assessment for adaptive behavior, social skills, behavioral function, medication side-effects, and psychiatric disorders." For example, in relation to the AAMR school-age scales, items were selected in part based on discrimination among institutionalized individuals and community dwelling individuals previously classified at different adaptive behavior levels, and among adaptive behavior levels in public school populations (Lambert et al., 1993b). To the extent that low income or very low income is more common among certain ethnic minority groups, however, differences in developmental trajectories for children may reflect differences in childrearing practices and stimulation that are associated with economic and social class and related levels of parental education (Hart, 2000; Hart & Risley, 1992; Walker et al., 1994). 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. Standard scores, age-equivalent scores, and percentile rank scores can be converted from raw scores on the adaptive behavior subscales and three factor scores for ages 3-21. Very recently Greenspan (1999) proposed ideas for assessing vulnerability in a comprehensive assessment of adaptive behavior or social competence. 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). Full details on standardization and reliabilities are provided in the manuals associated with the major adaptive behavior scales (Adams, 2000; Bruininks et al., 1996; Harrison & Oakland, 2000b; Lambert et al., 1993b; Sparrow et al., 1984b; see also Harrington, 1985). Table 4-1 shows the principal available adaptive behavior measures that are comprehensive in nature and their characterstics, including age range for use, age range of norm groups, date of publication, available versions, examiner requirements, appropriate scores for use in determining presence of adaptive behavior limitations, and assessed reliability of scores. Some scales contain provisions for alternative items or alternative performance of items. Formal Adaptive Behavior Assessments Assessments are used for many different purposes in the K12 educational setting. The second social-cognitive process is the generation of strategies for resolving social problems. 8 Special Education Assessments Find out about what tests are used to diagnose or help students with special needs. 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). The advantage of the method is that it frees the clinician from using a set of criteria that may be perceived as restrictive. But it does seem reasonable, based on clinical experience, that any cutoff scores used should classify a majority of people in this IQ range as having adaptive limitations consistent with mental retardation. When subscale scores are aggregated into summary scores, this results in a meaningful number of age-relevant items, although the items sampled in each subscale are limited. As environments change, people must learn new skills in order continue to meet the environmental demands. In infancy and early childhood: sensorimotor development, communication skills, self-help skills, socialization, and interaction with others; In childhood and early adolescence: application of basic academic skills in daily life activities, application of appropriate reasoning and judgment in mastery of the environment, and social skillsparticipation in group activities and interpersonal relations; and. 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). Multidimensional or Unidimensional? The domains assessed by adaptive behavior scales, and thus the individual items included on them, depend in part on the context, target age group, and purpose of the measure. A psychologist, social worker, or other professional who has appropriate training in interview techniques must complete these forms. 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. For example, a percentile rank of 41 indicates that the examinee scored higher than (or the same as) 41% of the age-matched norm . 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. self-care, home living, social skills, self-direction, health and safety, etc.). Adaptive behavior assessments are often used in preschool and special education programs for determining eligibility, for program planning, and for assessing outcomes. On one instrument, the items are shown to the respondent and the respondent is given responses from which to choose (e.g., Bruininks et al., 1996), while in another the interviewer is required to assess adaptive competencies through a general conversation with prompts such as Tell me about Thomasina's language skills (Sparrow et al., 1984a). Each of the four adaptive behavior measures included in the table collects or assesses information regarding developmental status or performance in the areas of motor development, activities of daily living, communication, social functioning, and personal functioning. For any given age, it is unlikely that developmental tasks will be oversampled. It does not have the problems with floor effects in diagnosing developmental delays at the youngest ages that are present in other adaptive behavior scales. 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. In an unstructured interview, the clinician applies personal, experience-based clinical norms to the adaptive behavior assessment. The Adaptive Behavior Assessment System (Harrison & Oakland, 2000a) is quite new and relatively untested, but its psychometric properties and norms extend to age 89. In using the term accompanied, the definition suggests that adaptive behavior is a supplementary variable to intelligence, although both criteria must be present. This allows the rater to obtain a complete picture of the adaptive functioning of the person being assessed. Scales developed subsequently improved on the simple rating format found in the ABS, which contained a finite list of problem behaviors rated according to the frequency of occurrence. Lowe and his colleagues (2007) categorized problem behavior into four broad groupings including self-injurious behavior, aggression toward persons, destruction of objects, and disruptive behavior. Taken together, these findings suggest that the primary cadre of psychologists with experience and expertise in the use of adaptive behavior measures, those who are most likely to use them in assessment and classification of mental retardation, consists of school-based practitioners. Adaptive behavior has been fundamental to conceptions of mental retardation at least since the early 19th century (Doll, 1936a, 1967). Deficits in adaptive behavior are defined as non-existent in an individual's effectiveness in meeting the standards of maturation, learning, personal independence, social responsibility and school performance. 2. Gresham and Elliott (1987) and Greenspan (1999) have argued that social competence has received too little attention in the conceptualization and measurement of adaptive behavior (Figure 4-1). Finally, it has been suggested that adaptive behavior and social competence represent an important facet of adjustment in academic contexts, as important if not more so than intelligence (Forness et al., 1998). 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. Vineland Adaptive Behavior Scales What it measures: How a child's daily living skills compare to those of other kids his age. Over the past 25 years there has also been further refinement of the parameters and structure of tests of adaptive behavior and social competence. Adaptive behavior measures differ regarding the use of typical or maximum performance methods. However, a recent surgeon general's report (U.S. Department of Health and Human Services, 2001) focuses on the miscommunication that may exist when the interviewer and the respondent speak different languages. It is, however, performance or typical performance that most adaptive measures address. As with the current Vineland, the content and scales of . Children with special needs might be delayed in these areas. A good example of adaptive social behavior is aggregation against predator. It also appears that community practitioners, aside from those associated with developmental disabilities clinics or centers or with community developmental disabilities services, may not be well versed in the use and interpretation of adaptive behavior measures or prepared to apply different measures in different situations for different purposes. AAMR departs significantly from other organizations by eliminating the grouping of individuals with mental retardation into levels of severity. Greenspan and colleagues (Greenspan, 1999; Greenspan & Driscoll, 1997; Greenspan & Granfield, 1992) have argued that social intelligence, some aspects of which are not contained on any current scales of adaptive behavior or social skills (e.g., credulity, gullibility), should be a key determinant of a diagnosis of mental retardation for adults (Figure 4-2). Vineland Adaptive Behavior Scales What it measures: How a child's daily living skills compare to those of other kids his age. In other instances, scales may be constructed such that they are relevant to only certain age groups (e.g., the motor scale in the Vineland ABS), or different versions of the same scale may be used in different settings (e.g., school versus residential and community settings). The 1992 AAMR definition requires that an individual show significant limitations in at least 2 of the 10 adaptive skill areas. The following areas by age should be adopted by SSA: Current science also suggests that several measures of adaptive behavior tap into these domains. What are examples of adaptive behaviors? Careful analysis of the appropriateness of the item content and density of specific measures is crucial. A consequence of this, according to Thompson et al., is the inability to develop precise measures of adaptive behavior that would objectively differentiate individuals by disability. Adaptive behavior assessment is a process that is used to determine an individual's level of functioning in daily life activities. In fact, semistructured interviews require the highest level of professional expertise, as the questioning and interpretation of answers requires a high level of training. Interpretation of ABAS-II Results Adaptive Behavior Composite Scores The General Adaptive Composite score (GAC) summarizes performance across all skill areas excluding Work. concluded: No single adaptive-maladaptive behavior assessment instrument completely measures the entire range of adaptive and maladaptive behavior dimensions. In Chapter 1 we summarized the history of definitions of mental retardation and discussed their relevance to the Social Security Administration's definition. These data are presented in Chapter 5. This is the key difference between these two forms of behavior. The value of such instruments will depend on careful decisions about instrument choice, score interpretation, and consideration of other information that bears on adaptive status. Social perception refers to an individual's ability to interpret or read relevant social messages from others (Maheady et al., 1984). In 1936, he introduced the Vineland Social Maturity Scale (VSMSDoll, 1936b), a 117-item instrument. Today, fulfillment of these personal and social responsibilities, as well as the performance of many other culturally typical behaviors and roles, constitutes adaptive behavior. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), published by the American Psychiatric Association (1994), definition of mental retardation also has a cutoff of two standard deviations below the mean for intelligence, making an IQ cutoff of 70 to 75 acceptable for a diagnosis of mental retardation. Getting dressed 4. With regard to identifying decision-making criteria, Division 33 presents the only definition that employs a statistical cutoff based on standard norms. Vineland Adaptive Behavior Scales are a valid and reliable test to measure a person's adaptive level of functioning. Comprehensive adaptive behavior measures are those that assess adaptive behavior through multiple items in multiple domains of functioning. The DABS measures adaptive behavior in these three areas: Conceptual skills: literacy; self-direction; and concepts of number, money, and time. In particular, criticism has focused on the inadequacy of existing techniques for measuring the social domain of adaptive behavior (MacMillan et al., in press). Validity can be categorized in terms of: (1) content validity (evidence of content relevance, representativeness, and technical quality); (2) substantive validity (theoretical rationale); (3) structural validity (the fidelity of the scoring structure); (4) generalization validity (generalization to the population and across populations); (5) external validity (applications to multitrait-multimethod comparison); and (6) consequential validity (bias, fairness, and justice; the social consequence of the assessment to the societyMessick, 1995). In addition, mitigating current circumstances (not speaking English) or past history (absence of schooling) were often ignored in the beginning years of intelligence testing (Kerlin, 1887; Wilbur, 1882). As the importance of adaptive behavior measures in classification of mental retardation has increased, this concern has been heightened as disproportionate numbers of minority children have been identified as having mental retardation, primarily because of low-income status and the overrepresentation of individuals with mental retardation among low-income people (Boyle et al., 1996). The ABS-S:2 has excellent interrater reliability. Table 4-4 presents examples of questions that can guide examiners in eliciting information regarding the three social-cognitive processes reviewed here. In our judgment, good clinical practice requires that data from standardized adaptive behavior scales be combined with other clinical or behaviorally oriented information in determining the presence or the absence of adaptive behavior deficits. A major reason why proper assessment of the social domain of adaptive behavior can be a challenge for eligibility examiners is that the limitations in social functioning in individuals with mild mental retardation are often difficult to quantify with available assessment methods. In the United States there have been significant concerns about the relationship between ethnicity or racial origin and performance on intelligence tests (Neisser et al., 1996). For example, an individual with mild mental retardation may be familiar with the routines and may benefit from the supports that staff provide in the supervised apartment program in which he lives. Although it is linked to AAMR by name, the ABS does not provide subscale scores in the 10 adaptive skill areas listed in the 1992 AAMR definition of mental retardation. Adaptive behavior assessment aims at assessing the emotional and social maturity of a child in comparison to his/her peers, along with practical life skills ("The diagnosis of intellectual disabilities," 2020). Best-practice guidelines require that clinicians using adaptive behavior measures employ those that are culturally compatible and have suitably contemporary and age-related norms. Adaptive Behavior Assessment Examples. In this format, the professional has the opportunity to ask questions that are at the appropriate level of sophistication and also appropriate to the cultural group of the respondent.
