For example, one needs to distinguish between an individual's deficit in a specific adaptive behavior skill, as opposed to a deficit in a larger domain. Auty and colleagues (1987) have found positive correlations between subtest scores on the TICE and supervisor-rated work skills, self-reported job satisfaction, and worker productivity among adults with mild mental retardation. Recent studies with these individuals have documented limitations in their reasoning about the consequences of strategies that make it difficult for them to select a social strategy that is appropriate for a given social situation. However, this also means that most scales are structured in steps that permit sampling of typical developmental tasks at each age. Children with mild mental retardation were most likely to have adaptive behavior skills consistent with marked limitation (e.g., 2 SDs) in the domains of functional academics, communication, and community use. 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). Adams (2000), in contrast, uses a mixture of typical performance with third-party respondents and maximum performance operations. Making a phone (or video) call is an example of adaptive behavior that changed over time. However, because several adaptive behavior scales contain maladaptive components, it is worth noting important challenges to reliable measurement. 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. Factor analysis results do not support the existence of more than one overall ABAS general factor. 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. Still another way to extend respondent usefulness has been to permit guessing on items involving behaviors that have not been observed (e.g., Harrison, 1984; Harrison & Oakland, 2000a). 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. Social skills: interpersonal skills . The 1961 manual (Heber, 1961) discussed adaptive behavior with respect to maturation, learning, and social adjustment. Adaptive behavior measures are useful in the identification of limitations concurrent with an IQ significantly below average. 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. 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). <p>Adaptive Behavior Assessment System Third Edition (ABAS-3) gives a complete picture of adaptive skills across the lifespan. (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. 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. 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. The purpose of doing a behavioral assessment is to understand and to explain how behavior can affect a child or an individual depending on the environment. 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. As a result, they often rely on generic, one-size-fits-all strategies, such as appealing to an authority, rather than adjusting their strategies in accordance with situational demands. Assessment of adaptive behavior should include social competence, play and leisure skills, and self-help/independent living skills. Food handling 7. 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 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. They have provided valuable information that has informed decision making about interventions to improve the social functioning of individuals with mental retardation. The Vineland-3 is a standardized measure of adaptive behavior-the things that people do to function in their everyday lives. The committee discussed the use of specific numeric cutoff points at which a marked deficit is present. Vineland Adaptive Behavior Scale (VABS): This test measures the social skills of people from birth to 19 years of age. Observations of the individual in real-life, everyday situations 2. In so doing, AAMR ignores the substantial theoretical and empirical foundation that validates the difference between individuals with mild mental retardation and other individuals with mental retardation (MacMillan et al., in press). Interpretation of ABAS-II Results Adaptive Behavior Composite Scores The General Adaptive Composite score (GAC) summarizes performance across all skill areas excluding Work. The Social Skills Rating System, described below, is a behavior rating scale that was developed to provide this information for students. Chapter 4, The Role of Adaptive Behavior Assessment. It was developed to be consistent with the 10 AAMR adaptive skill domains, and, depending on the weight placed on using the AAMR definition for diagnosis by a clinician, this may be a relevant characteristic. Typically these measures are structured in terms of factors, domains, and subdomains or scales. The dimensions of adaptive behavior and social skills in the Gresham and Elliott model are surprisingly similar to the 10 adaptive skill areas in the 1992 AAMR definition of mental retardation. The committee therefore, makes two major recommendations to SSA: Recommendation: Standardized adaptive behavior instruments should be used to determine limitations in adaptive functioning. Vineland Adaptive Behavior Scales are a valid and reliable test to measure a person's adaptive level of functioning. The social domain is particularly important to assess for individuals with mild mental retardation because prominent limitations that these individuals experience are often in the domain of interpersonal relationships, rather than in skill domains that are not predominantly social in nature (e.g., activities of daily living, motor skills). 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 this reason, some manuals recommend that clinicians fully explore the nature of tasks that the focal person performs that may be age typical (e.g., Sparrow et al., 1984a). At the same time, it has been noted that use of adaptive behavior measures in the process of identifying children with mild mental retardation, especially, may be forgone in many schools because the academic failures or behavioral problems that prompt teacher referral of students, in and of themselves, may be considered valid indicators of limitations, deficits, or delays in adaptive behavior (McCullough & Rutenberg, 1988). 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). 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. This is perfect for any special education, life skills, or autism or ABA classroom. 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. 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. 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 the committee's view, the use of standardized measures of adaptive behavior is potentially valuable in the overall assessment of adaptive behavior. Because clinicians are encouraged to utilize multiple measures in diagnosis, these other measures may be useful in providing supplemental or complementary information. 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. These assessment instruments, which have been useful in instructional contexts, can also be valuable for the evaluation of an individual's eligibility for SSA services. The ABS-S:2 provides norms only through age 21 and includes some content specifically appropriate for school settings rather than adult environments. NOTE: When assessed as mean or total scores, row differences were significant at p < .0001 with t-tests for matched samples. Reliability is good. Unlike intelligence tests, which measure maximum performance, adaptive behavior assessment focuses on what the individual typically does. McGrew and Bruininks (1989) and Thompson et al. 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. As environments change, people must learn new skills in order continue to meet the environmental demands. (1999) is the most recent summary of studies using factor analysis; it concludes that adaptive behavior is a multidimensional construct. These measures have excellent psychometric properties, with reliabilities of about .90. The issues of cross-cultural, racial, ethnic, and subcultural biases are of concern to some who view many aspects of adaptive functioning as culturally determined (Boyle et al., 1996; Valdivia, 1999for a general discussion see the section Sociocultural Biases). This chapter contains material drawn from an unpublished paper commissioned by the committee from Sharon Borthwick-Duffy, Ph.D., University of California, Riverside. It requires an individual to demonstrate adaptive skills, rather than using a third-party informant or self-report to gather information on typical behavior. Individuals or third-party respondents are asked to indicate their usual feelings or behaviors, not their best or most positive feelings or behaviors. Examples include social skills, cleaning, and personal grooming. Scales typically include items that permit behavioral assessments for young children and adolescents without disabilities (i.e., superior behavioral development or skill). Social-cognitive assessments have already demonstrated their usefulness as a supplement to standard adaptive behavior rating scales. In contrast, the other definitions employ more qualitative terms, which are open to interpretation in describing deficits and limitations in adaptive behavior. These practices persisted over that century because of the absence of standardized assessment procedures. Adult norming samples are often included as well, but they tend to consist of people with already identified disabilities. The standardization sample was proportional in demographic characteristics to the 1980 census data. Adaptive behavior is the collection of conceptual, social, and practical skills that all people learn in order to function in their daily lives. Jane obtained a GAC score of 72. 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. It may, however, be useful for identifying some of the issues likely to arise in setting a specific numeric cutoff point. The number of items associated with each descriptive category must be sufficient to provide a scale and to be applicable across age ranges. As previously noted, primary concerns in the use of adaptive behavior scales in eligibility determination decisions center on informant bias. In using the term accompanied, the definition suggests that adaptive behavior is a supplementary variable to intelligence, although both criteria must be present. That is, current science suggests that there are various domains of behavior that form the construct of adaptive behavior. 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 three processes occupy a prominent place in most theoretical models of social cognition (e.g., Crick & Dodge, 1994; Gumpel, 1994; Leffert & Siperstein, in press; McFall, 1982). Adaptive Functioning Adaptive functioning is affected by three basic skill sets: Conceptual This includes reading, numbers, money, time, and communication skills. By eliciting information about an individual's performance of these processes, the examiner can increase the likelihood of detecting impairments in social functioning that often characterize this population. Moreover, the findings suggest that eligibility criteria for SSI and DI applicants with IQs in the range of 2 to 2.66 SDs, by including the presence of marked limitations in activities of daily living, communication, social functioning, and personal functioning, will exclude a substantial number of people with IQs in this range. It also allows for reconciliation of ratings among these informants. Purpose, defnition, and two examples of adaptive behavior assessments Defnition of six specialized assessment terms both of a content and statistical nature including an explanatory example of each used in formal adaptive behavior assessments 8 Special Education Assessments Find out about what tests are used to diagnose or help students with special needs. The DSM-IV definition identifies four levels of mental retardation based on IQ: mild, moderate, severe, and profound. The DABS measures adaptive behavior in these three areas: Conceptual skills: literacy; self-direction; and concepts of number, money, and time. The Independent Living Scales (ILSLoeb, 1996) were designed to assess the degree to which older adults are capable of caring for themselves (i.e., functional competence). The advantage of the method is that it frees the clinician from using a set of criteria that may be perceived as restrictive. Washington (DC): National Academies Press (US); 2002. Vineland Adaptive Behavior Scales What it measures: How a child's daily living skills compare to those of other kids his age. This problem, and recommended strategies to avoid errors in diagnosis, are discussed in the section on norms. 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. 7-8). The instrument's structure must guide interpretation. PDF. How it works: Someone who knows the child well fills out a questionnaire or answers questions about him. Beltran's Behavior Basics. Physical/developmental and vocational/community dimensions were found less often. assessment of Jane's adaptive behavior. Their model divides social competence into two overall dimensions: (1) adaptive behavior, which includes the factors contained on most adaptive behavior scales (independent functioning, self-direction, personal responsibility, vocational activity, functional academic skills, physical development) and (2) social skills, including domains that are likely to be most key to identifying mental retardation at the borderline levels (interpersonal behaviors, self-related behaviors, academic-related skills, assertion, peer acceptance, communication skills). As there is no research yet on credulity in people with mental retardation, these proposals for assessment are unlikely to be found in practice in the next several years. Instead, it may be possible to establish only that their skills are superior to those achieved by other young adults with mild mental retardation, and they may sometimes fall in the normal range of performance of similar age peers. 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. Generally, these instruments do not have well-established norms but rather have been assessed for their sensitivity with diagnosed cases (e.g., Reiss & Valenti-Hein, 1994), and some scales are more suitable for youth than for children: the Assessment of Dual Diagnosis (Matson & Bamburg, 1998); the Psychopathology Instrument for Mentally Retarded Adults (Balboni et al., 2000; Linaker, 1991; Sturmey & Ley, 1990; Watson et al., 1988); and the Reiss Screen for Maladaptive Behavior (Havercamp & Reiss, 1997; Prout, 1993; Sturmey & Bertman, 1994) For practitioners skilled in clinical interviewing, a field-tested adaptation of a structured clinical interview is available. Reprinted with permission. In an unstructured interview, the clinician applies personal, experience-based clinical norms to the adaptive behavior assessment. No one instrument produced a factor structure that included all of the domains that were identified by the American Association on Mental Retardation (1992). One concern that emerged over time was that it was developed and normed for use with children and youth. The Vineland-3 is a standardized measure of adaptive behavior--the things that people do to function in their . 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. Adaptive behavior. Manuals for the major adaptive behavior scales encourage the use of multiple informants, for example, teachers and parents. This nomenclature has dimensions of impairments of body functions, impairments of body structures, activity limitations and participation restrictions, and environmental factors. It is reported to be appropriate for ages 5-22, yet it may not have a sufficient ceiling to discriminate performance levels among children above age 14 (Evans & Bradley-Johnson, 1988). 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. Possibly the most thoroughly researched and well understood instrument to assess both prosocial and problem behavior among children generally is the Achenbach Child Behavior Checklist (CBCsee Achenbach & Edelbrock, 1978). 8. Here we review data from the only adaptive behavior test manual that could provide some guidance about the use of cutoff points for adaptive behavior assessment. It is important to note that the Division 33 definition places equal importance on the constructs intellectual functioning and adaptive behavior. Each of these scales (except the Adaptive Behavior Assessment System) has been reviewed extensively and compared with others in detailed reports. Some caution is needed in interpreting these findings, because the study is small and unrepresentative. There is a much larger number of scales that do not have extensive norms but may nonetheless be suitable as a means of gathering and summarizing information that can be assessed on a clinical basis. It should also be noted, however, that there is no gold standard against which cutoff scores could be appraised, or research from which a true proportion of people with observed IQs in the range of approximately 65-75 who manifest adaptive limitations consistent with mental retardation may be directly projected. 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. The ABI has a normative sample representative of all school-age children, including those with disabilities, and of a sample with mental retardation. Breadth of Domains. Making friends Teaching how to clean oneself, brush hair and teeth, wear clean clothes and make one's presence neat and presentable. Social competence model. (1995) found that only 13 percent of respondents in the sample of clinical psychologists engaged in ability testing as part of their clinical practice, but 66 percent engaged in intellectual assessment. 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). Gifted Testing. Adaptive behavior is the skill set required for a person to care for themselves. In unpublished data on some 27,000 people with mild mental retardation, between 75 and 100 percent of participants obtained perfect scores (100 percent) on three of five indices of one scale (J.W. Children with special needs might be delayed in these areas. There are a small number of well-normed adaptive behavior scales that are especially suitable for use in initial determinations for children and youth with possible mental retardation. Interview methods recommended for different measures vary from high to low structure. Methodologies for assessing consequential reasoning have existed for several decades. The result is an overidentification of skill limitations among minority children. Assessments are used for many different purposes in the K12 educational setting. 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. The distinction between maximum performance and typical performance assessments might be illustrated with some common adaptive behavior items. Even a statement such as "Emily is aggressive toward her peers" is too vague to target for intervention. In order for the assessment to be clinically and scientifically meaningful, it is important that the assessor be sufficiently trained in using and interpreting appropriate instruments. In addition to rating skill performance, raters also specify whether each skill is critical to success in the environment in which the child is observed, i.e., school or classroom. The typical adaptive behavior inventory inquires about both the individuals' skills or abilities (what they can do) and about what they usually do in various circumstances (performance of skills or typical performance). This usually entails behavioral patterns that are dysfunctional to the individual. Thus, most norming samples, item development, and scale selection have been targeted at groups ages 3 to 18 or 21. This is usually a parent or teacher. There are a number of ways to assess the level, quality, and pattern of adaptive functioning, each with its own strengths and weaknesses. The adaptive behavior scales described above have been consistently identified in research and practice reports as meeting criteria of technical excellence in measurement. Reviews of the ILS have been generally negative, and it may not be suitable for disability determination purposes. ASEBA behavior rating scales include the Child Behavior Checklist (CBCL), the Caregiver-Teacher Report Form (C-TRF), the Teacher Report Form (TRF), the Youth Self-Report (YSR), the Adult Behavior Checklist (ABCL), the Adult Self-Report (ASR), the Older Adult Behavior Checklist (OABCL), and the Older Adult Self-Report (OASR).
