Whereas situational and functional assessment are appropriate in intervention design for maladaptive behavior or behavior disorders or problems, norm-referenced or criterion-referenced instruments are appropriate for initial assessment (Reschly, 1992). Novel frameworks for conceptualization of adaptive behavior have been proposed (American Association on Mental Retardation, 1992), and conventional frameworks have been endorsed for application in differential diagnosis and classification practices (Jacobson & Mulick, 1996). However, if functional independence is to be considered within the context of the environments and social expectations that affect his or her functioning (Hill, 1999), interpreting scores without considering opportunity and societal expectations for a person with physical limitations could be problematic for a diagnosis of mental retardation. If not, diagnosticians would have to consider a profile of adaptive behavior deficits that takes all domain scores into account. Adaptive behavior also includes the ability to work, practice social skills, and take personal responsibility. Adaptive Behavior Assessment Examples. Observations of the individual in real-life, everyday situations 2. Some organizations are too rigid for adaptive performers such that they are likely to leave. (1999) have concluded, for example, that the number of factors emerging from factor analyses depends on whether data were analyzed at the item, parcel, or subscale level, with fewer factors found for subscale-level data than item- or parcel-level data. For the Social Skills and Vocational Success, Chadsey-Rusch (1992) described three measurement approaches to operationalize a definition of social skills, including (1) the perception of others in the workplace, especially employers, (2) the goals and perceptions of the target individual, and (3) performance of social behaviors in natural contexts. 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.

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. (1999) reviewed studies that reported factor analyses of adaptive behavior measures. 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. The instrument must be appropriate to the age of the client and the client's approximate functioning level. Reprinted with permission. Vineland Adaptive Behavior Scales are a valid and reliable test to measure a person's adaptive level of functioning. 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). For example, saying a student is "always getting in trouble" is vague and not measurable. Adaptive behavior assessment is a process that is used to determine an individual's level of functioning in daily life activities. Vineland Adaptive Behavior Scales What it measures: How a child's daily living skills compare to those of other kids his age. Also, current measures also evidence strong validity, as described in the chapter. 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). Useful score scales and appropriate norms are vital features of adaptive behavior instruments used in diagnostic decisions. At the turn of the century, intelligence assessment placed primary emphasis on moral behavior (which largely comports with the current construct of social competence) and on the pragmatics of basic academics. These studies also show that use of adaptive behavior scales has been growing over time (Hutton et al., 1992; Ochoa et al., 1996; Stinnett et al., 1994). 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. Adaptive behavior is the skill set required for a person to care for themselves. The adaptive behavior construct has both typical performance and maximum performance elements, a characteristic that complicates measurement operations. These measures have excellent psychometric properties, with reliabilities of about .90. Furthermore, behavioral, emotional, and social difficulties of the mildly mentally retarded . 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). AAMR departs significantly from other organizations by eliminating the grouping of individuals with mental retardation into levels of severity. 8. As a result, the committee commissioned Monte Carlo simulations to understand better the implications of requiring a specific numeric cutoff point. Gullibility/Credulity Component of Social Competence. Food handling 7. Retaining all features that made the second edition the preferred instrument for evaluating adaptive behavior, the ABAS-3 is even easier to administer and score. Reviews of the ILS have been generally negative, and it may not be suitable for disability determination purposes. Is adaptive behavior a set of abilities and skills useful in coping with environmental demands that are mastered by the individual? Both legislative action and judicial decisions at the federal level have focused on concerns that parents may misinform clinicians regarding their children's skills in order to obtain SSI benefits. Nonetheless, available research on the clinical use of adaptive behavior scales for diagnosis and treatment-related purposes by either school psychologists or community clinical psychologists appears to be relatively sparse and does not focus on groups of people with mental retardation, as such (i.e., Clinger et al., 1988; McNamara et al., 1994; Pearson & Lachar, 1994; Roberts et al., 1993; Voelker et al., 1990; Wolber et al., 1997). They open a window into a child's inner world and often serve as a starting point for therapy. Most adaptive behavior scales contain factors addressing interpersonal relationships or social skills, but they do not address overall social competence. It also allows for reconciliation of ratings among these informants. It can be a habit picked up at an early age or can be a behavior that starts after a major life change, illness, or traumatic event. ABS-RC:2 norms are not available for adults with typical functioning, and most norm-referenced scores provide comparisons only with adults with developmental disabilities. The initial, and probably primary, application of adaptive behavior scales in clinical practice has been to assess the behavioral development of children thought to have mental retardation. Adaptive behavior is defined as the set of skills that individuals should be able to perform at a certain age. These concerns are heightened when informants have a stake in the outcome of the assessment (e.g., when responses may affect eligibility for services). For example, an item may tap skills associated only with childhood (e.g., performing a specific activity or completing a task with adult assistance in an age-typical manner) or with adulthood (e.g., menstrual care for an adult or adolescent woman). This information may otherwise be lacking because of inadequacies in existing adaptive behavior measures. The DSM-IV definition identifies four levels of mental retardation based on IQ: mild, moderate, severe, and profound. 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. Our review of the practice literature reveals that adaptive behavior scales are in wide use by some groups of clinicians. Under ideal circumstances, adaptive behavior measures should be administered in an examinee's or informant's primary language. form to factor analysis results. Grooming 2. 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). Hill (1999) also emphasized that behaviors that interfere with a person's daily activities, or with the activities of those around him or her, should be considered maladaptive behavior, not the lack of adaptive behavior. Diagnostic decisions about mental retardation nearly always involve normative comparisons using various derived scores. The number of items associated with each descriptive category must be sufficient to provide a scale and to be applicable across age ranges. The Vineland-3 is a standardized measure of adaptive behavior--the things that people do to function in their . Most adaptive behavior instruments have a number of subscales or subtests that measure four to six broad areas of independence. The use of a formal adaptive behavior measure allows . Adaptive behavior is generally not a mental health issue, since the focus is on developing positive behaviors, rather than deficits. This use may result from concerns among clinicians about the robustness of adaptive behavior measures. 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).

Because clinicians are encouraged to utilize multiple measures in diagnosis, these other measures may be useful in providing supplemental or complementary information. The Batelle Developmental Inventory (BDINewborg et al., 1984) is a developmental scale, rather than an adaptive behavior scale, and is appropriate for children from birth to age 8 (Spector, 1999). 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. 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. Referring to the dual purpose of adaptive behavior scales, Spreat (1999) concluded that it is unrealistic to think that the same test can be used for program evaluation, diagnosis, classification, and individual programming (p. 106). It is important to note that the Division 33 definition places equal importance on the constructs intellectual functioning and 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. Social-cognitive assessments have already demonstrated their usefulness as a supplement to standard adaptive behavior rating scales. In recent years, existing operational definitions of adaptive behavior and techniques for measuring adaptive behavior have been criticized as being inadequate for determining the presence of significant limitations in individuals with mild mental retardation. Vineland Adaptive Behavior Scales What it measures: How a child's daily living skills compare to those of other kids his age. 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. Is the person familiar with and able to think of a variety of strategies that are potentially appropriate for resolving social problems? For any given age, it is unlikely that developmental tasks will be oversampled. Inventories or checklists that attempt to assess vocational interests, emotional status, and personality traits nearly always are typical performance measures. Rather than weighing the likely outcomes of enacting a particular strategy in a given situation, these individuals tend to render global judgments (e.g., whether a strategy is generally a good thing or bad thing to do) when evaluating behavioral options. Generally, adaptive. Direct measures from target individuals involve presenting them with hypothetical situations and conducting direct observations. 1. 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. Assessments are used for many different purposes in the K12 educational setting. 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). Typically these measures are structured in terms of factors, domains, and subdomains or scales. The definitions also vary as to whether they consider adaptive behavior to be made up of a single factor or to have multiple factors or domains. Their view has been both supported and disputed in the past two decades, and there are currently firm adherents on each side of this issue. Current measures evidence acceptable interrater and test-retest reliability, with consistency scores at levels of .90 and above (seldom at a level below .80) for clinical and normative subgroups, partitioned by age and clinical variables. This attention to and concern about the assessment of social behavior is hardly surprising, given the prominent place that social behavior has historically occupied among the domains of day-to-day life that constitute adaptive behavior for individuals with mental retardation. It includes two adult forms, including a self-report and a report by others, and norms that extend well into adulthood.
