In describing mild mental retardation, there is minimal reference to adaptive behavior problems, except for the inclusion of low academic skill attainment.. 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. The definition also views adaptive behavior as a multidimensional construct, in that the definition is expanded to include two or more factor scores below two or more standard deviations. It appears to have good potential for assessing adaptive behavior for diagnostic purposes. Children with special needs might be delayed in these areas. The Vineland Adaptive Behavior Scales (VABSSparrow et al., 1984a) have their conceptual roots in the Vineland Social Maturity Scale (Doll, 1936b), although overlap between the original and the new scales is minimal (Kamphaus, 1987b). Rather, there is a standard clinical methodology that consists of presenting the individual with a hypothetical situation in the form of a story and asking What would you do if this happened to you? The Social Problem-Solving Test (Castles & Glass, 1986) is an example of an assessment instrument employing this methodology that was specifically designed for use with individuals with mental retardation. 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. At the workplace, for example, overdependence on the strategy of appealing to a supervisor, regardless of the nature of the problem, can be a problem in creating tension with peers or in creating a perception that the person cannot function autonomously in a work setting. Of the various social perception assessment instruments that have been developed, the TSI is the instrument that has been used most widely to assess social perception skills in this population (de Jung et al., 1973; Matthias & Nettelbeck, 1992). In an unstructured interview, the clinician applies personal, experience-based clinical norms to the adaptive behavior assessment. Another psychometric concern is whether the norming samples are adequate. Reprinted with permission. Furthermore, these limitations may be more noticeable in certain settings or circumstances than in others (Greenspan, 1999). 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). 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). These domains vary by age, consistent with the development of adaptive behavior. To the extent that SSSQ data can predict entry or retention of competitive, gainful employment among people with mental retardation, it may have utility. 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. It contains broad domains similar to those found on adaptive behavior scales, which include: personal-social, adaptive, motor, communication, and cognitive. The residential and community version, ABS-RC:2, was developed to be appropriate for use with persons through 79 years of age. 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 . Because the sample for mild mental retardation shown in Table 4-3 was drawn from a school-age sample, some members of the group may have had IQs above 70 (i.e., less than 2 SDs below the mean). Assessments. Several studies have shown significant and meaningful correlations between the BDI and other measures of cognitive, adaptive, language, and social functioning, with samples of children with and without disabilities (Bailey et al., 1998). Among these four definitions, there is little variation in the intelligence construct for individuals with mental retardation. Although research from the 1970s and 1980s found comparable performance on adaptive behavior scales among majority and minority ethnic groups (Bryant et al., 1999; Craig & Tasse, 1999), linguistic factors remain a concern. Clearly, examiners need to be concerned about whether available instruments and practices for assessing adaptive behavior adequately document critical difficulties in social functioning that prevent individuals with mild mental retardation from fulfilling key roles and expectations in society. The adaptive behavior scales described above have been consistently identified in research and practice reports as meeting criteria of technical excellence in measurement. In the mastery approach, examinees are encouraged to do their best, and testing conditions are designed to elicit maximum performance. This leads to some unique problems with these measures. They can contribute to accurate and appropriate clinical diagnosis of concurrent conditions that may meet listing requirements for SSI and DI as an alternative to assessment of adaptive behavior. In some definitions (Division 33 and AAMR), adaptive behavior is construed as distinct from intellectual functioning and of equal importance, while in other definitions it is considered a result of deficits in intellectual functioning. 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 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). 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. Consider using a formal rating scale (for example, the Aberrant Behavior Checklist or Adaptive Behavior Scale) to provide baseline levels for the behaviour and a scale (such as the Functional Analysis Screening Tool) to help understand its function. Adaptive behavior is defined as the set of skills that individuals should be able to perform at a certain age. 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. Response options such as never, sometimes, and always or Likert-type response formats using a five- or seven-point continuum with anchor statements like very good, good, acceptable, poor, and very poor are open to a variety of response sets. However, the simplicity and lack of reliability or validity of many such procedures render them less useful than more complex measures administered professionally. Edger Doll produced form board speeded performance tests, which were analogues to everyday vocational tasks. 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. 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. The VABS-3 assesses three domains of adaptive behaviors: communication, daily living, and socialization, with an additional optional motor skills assessment. 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. 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). Consequently, they have difficulty evaluating which potential strategy is best to enact in a particular situation (Hickson et al., 1998; Jenkinson & Nelms, 1994). Adaptive Behavior Is adaptive behavior the consistency with which an individual performs various skills in coping with environmental demands? . However, teachers have limited opportunities to observe all behaviors on the VABS-C and must necessarily provide estimates of behaviors that do not occur in the school context. In describing the different severity levels of mental retardation, the ICD-10 guide presents IQ levels not as strict cutoffs but as guides to categorizing individuals with mental retardation. Thus, most norming samples, item development, and scale selection have been targeted at groups ages 3 to 18 or 21. Comprehensive, convenient, and cost-effective, this behavior rating scale . Does the person recognize that a social problem has occurred? The advantage of the method is that it frees the clinician from using a set of criteria that may be perceived as restrictive. . Limitations in present functioning must be considered within the context of community environments typical of the individual's age, peers, and culture. The ABS-S:2 has excellent interrater reliability. (1991) and Widaman and McGrew (1996) concluded that evidence supported a hierarchical model with four distinct domains: (1) motor or physical competence; (2) independent living skills, daily living skills, or practical intelligence; (3) cognitive competence, communication, or conceptual intelligence; and (4) social competence or social intelligence. By the close of the 19th century, medical practitioners diagnosing mental retardation relied on subjective or unsystematic summaries of such factors as age, general coordination, number of years behind in school, and physiognomy (Scheerenberger, 1983). There are actually three scales, including a survey form (VABS-S) and an expanded form (VABS-E), which uses a conversation data gathering format during interviews with parents or guardians. Greenspan (1999) argues that the victimization of people with mental retardation, observed in social and economic exploitation, is a more central (and generally more subtle) problem that goes to the heart of why people with mental retardation are considered to need the protections (ranging from in-home services to conservators) associated with the label (p. 69). 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. Adaptive behavior is the skill set required for a person to care for themselves. Independence of Domains. 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). In their review, Thompson et al. Smith (1989) cited many problems with the norm tables but concluded the ABI could contribute some information to the determination of mental retardation. 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. Correspondence Between SSI Classification Domains and Domains or Subdomains in Prominent Adaptive Behavior Measures. (1991) found that two adaptive behavior scales ranked 20th and 21st among 29 specific psychological assessment measures used by psychologists serving adolescents, and they were used frequently by fewer than 10 percent of practitioners. It is possible that the use of these measures is diminishing in local educational agencies, with increasing emphasis on specific educational classification in many states. In a 1990 survey, Archer et al. It is clear that different scales place different levels of emphasis on different adaptive behavior domains. Refusal to perform a task that a person is capable of doing is also a reflection of problem behavior and should not be considered in relation to adaptive behavior. . Table 4-3, adapted from Harrison and Oakland (2000b), shows the percentage of adaptive behavior domain scores for a sample of children with mild mental retardation (N = 66) and controls without mental retardation matched for gender, age, and socioeconomic status (N = 66) that scored below the 2 SD standard on the teacher form of the ABAS. Also, current measures also evidence strong validity, as described in the chapter. Perceptions of others are typically measured by sociometric ratings and behavior rating scales. Moreover, the ABAS is appropriate for use with children (age 5 and older) as well as adults. 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. Standardization is the process of . By contrast, maladaptive behaviors. Since other norms should be used for determining a diagnosis of mental retardation, according to the manual, this should not be a problem in the current SSA context. 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). (1999) reviewed studies that reported factor analyses of adaptive behavior measures. Specifically, a comprehensive adaptive behavior assessment should include information obtained from: 1. They open a window into a child's inner world and often serve as a starting point for therapy. Overall, as a supplement to standardized adaptive behavior assessment scales, social-cognitive assessment has the potential to contribute to the improvement of SSI and DI eligibility determination practices by enriching the pool of relevant information that is available for resolving uncertainty in decisions regarding impairment in the social domain. In adolescence and adult life: vocational and social responsibilities. In 1936, he introduced the Vineland Social Maturity Scale (VSMSDoll, 1936b), a 117-item instrument. Interview methods recommended for different measures vary from high to low structure. In this definition, the order of the constructs can be switched without affecting the validity of the definition. This important finding has direct implications for definitions that require limitations to be observed in a specific number of areas. SOURCE: Data from Harrison & Oakland (2000b, p. 89). Furthermore, behavioral, emotional, and social difficulties of the mildly mentally retarded . <p>Adaptive Behavior Assessment System Third Edition (ABAS-3) gives a complete picture of adaptive skills across the lifespan. The TICE, which is commercially available, consists of two subtests that assess the individual's ability to evaluate strategies in relation to the situational demands of two distinct social interaction contexts common in work settings: interaction with coworkers and interaction with supervisors. (5) $6.99. Cross-cultural and cultural subgroup studies of adaptive behavior differences among ethnic, racial, or national groups are certainly needed, but evidence for substantial relationships between racial or ethnic group membership and performance on adaptive behavior scales, unmediated by socioeconomic differences, is very limited. SSA guidelines further clarify the intent and nature of activities of daily living and social functioning for adults, and personal functioning for younger and older children, closely paraphrased below: The overall correspondence of several adaptive behavior measures to the content within the functional areas that are considered in ascertaining marked limitations is shown in Table 4-2. Typically these measures are structured in terms of factors, domains, and subdomains or scales. However, this also means that most scales are structured in steps that permit sampling of typical developmental tasks at each age. 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). It consisted of 3,000 children ages birth through 18 years 11 months of age, including 99 children in special or gifted education among the 2,500 who were of school age. It also differs from other adaptive behavior scales because it is administered as a test directly to the individual and, as such, does not measure typical performance in real life. Haring (1992) found this to be an advantage in terms of its excellent reliability but noted that there were concerns about validity. Reliabilities are initially assessed at the item level and then at the scale and factor levels. In conjunction with the ICIDH-2, WHO has developed the World Health Organization Disability Assessment Schedule II (WHODAS II), which, in its most extensive form, contains 36 items tapping domains of: (1) understanding and communicating, (2) getting around, (3) self-care, (4) getting along with others, (5) household and work activities, and (6) participation in society.
