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). Chapter 4, The Role of Adaptive Behavior Assessment. The ABI has a normative sample representative of all school-age children, including those with disabilities, and of a sample with mental retardation. Valid assessment considers cultural and linguistic diversity as well . The issue of sociocultural bias also arises in the context of the adaptive behavior interview. 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). Adaptive Behavior Skills Assessment Guide. The AAMR definition is accompanied by five major principles for the assessment and understanding of adaptive behavior: 1. With regard to the direct assessment of processes, the overarching construct of social cognition has been put forth by developmentalists over the past four decades (e.g., Crick & Dodge, 1994; Dodge, 1986; McFall, 1982; Trower, 1982). The most widely used measures use a typical performance approach involving third-party respondents (Bruininks et al., 1996; Harrison & Oakland, 2000b; Lambert et al., 1993b; Sparrow et al., 1984b), although several differences exist among the response formats for items in 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. Does the person accurately interpret others' emotions and intentions on the basis of the available cues? Thus, some of the concerns about cultures that are less accepting of mental illness labels than the majority culture are much less relevant to adaptive behavior assessment. Nonetheless, culturally competent assessment practices require consideration of the developmental impacts of cultural practices or language differences among examiners, examinees, and informants that may affect the validity of the clinical information collected and interpreted. Research studies in the past decade that employ adaptive behavior measures have used them as outcome measures or to study the structure or dimensions of adaptive behavior, rather than behavioral development. These other bits of data could include a review of developmental and social history, direct observation of the individual's behavior, verbal reports from interviews, and the use of the other structured and semistructured interviews. Finally, the difficulties and complexities of differentiating mild mental retardation from its absence or from other disabling conditions (e.g., Gresham et al., 1995; MacMillan, Gresham, et al., 1996; MacMillan, Siperstein, & Gresham, 1996) have remained an enduring concern in both professional practice and policy formulation. Thus, most norming samples, item development, and scale selection have been targeted at groups ages 3 to 18 or 21. 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). 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 an unstructured interview, the clinician applies personal, experience-based clinical norms to the adaptive behavior assessment. 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 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. The advantage of the method is that it frees the clinician from using a set of criteria that may be perceived as restrictive. Adaptive behavior refers to the ways individuals meet their personal needs as well as deal with the natural and social demands in their environments (Nihira et al., 1993). There are some techniques that extend the range of appropriate respondents. Because adaptive behavior scales are designed with applicability for a wide age range but with primary emphasis on childhood and adolescence, some items may not be suitably worded or may not reflect a performance that is age-relevant. Measures used in schools may not need a work domain, for example, if students are too young for employment or the school does not have a work experience program. 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. There are many different ways to assess . For the Adaptive Behavior Assessment System (Harrison & Oakland, 2000a), the norming groups for 5- to 21-year-olds included 1,670 (parent form) to 1,690 (teacher form) children; for 16- to 89-year-olds, the norming groups included 920 (rated by others) to 990 (self-report) adults without disabilities throughout the United States. 1. Connect with AAIDD on Social Media Behavior . Sociometric ratings provide useful information but are impractical for diagnostic purposes, and the use of nonstandardized rating forms is not recommended for diagnosis of significant limitations in social skills. concluded: No single adaptive-maladaptive behavior assessment instrument completely measures the entire range of adaptive and maladaptive behavior dimensions. Generally, adaptive behavior assessment involves obtaining information from parents, legal primary caregivers, or even teachers about a child with a learning disability to determine their strengths and weaknesses and how well they can perform independently at home, school, and in the community. 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. Each request for ABT must include an assessment involving the use of a standardized assessment (for example, Verbal Behavior Milestones Assessment and Placement Program [VB-MAPP], the Vineland Adaptive Behavior Scale [Vineland], the Autism Diagnostic Observation Schedule [ADOS], etc.). Dr. Smagula is the 2022 . The decision on which standardized instrument to use must be informed by knowledge of the following characteristics of clients, respondents, and instruments. Adaptive behavior assessment information can provide information needed to determine an individual's eligibility for special education services. 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. Social cognition encompasses such constructs as social problem solving (Spivack & Shure, 1974), decision making (Hickson & Khemka, 1999), and social and emotional learning (Elias et al., 1997). A good example of adaptive social behavior is aggregation against predator. 5.0. Based on the ratio of marked deficits in the two groups (column 4), children with mild mental retardation were much more likely to have deficits in functional academics (especially), self-care, and community use and more likely to have deficits in social, self-direction, school living, and communication than children without mental retardation. Adaptive Behavior 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. In contrast, the other definitions employ more qualitative terms, which are open to interpretation in describing deficits and limitations in adaptive behavior. 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. Moreover, the ABAS is appropriate for use with children (age 5 and older) as well as adults. Through the assessment of strategy generation, researchers have been able to evaluate an individual's fund of social knowledge (i.e., his or her repertoire of social strategies), as well as the ability to adapt to varied social situations by generating situationally appropriate strategies. Doll emerged as a leader in the development of a psychometric measure of adaptive behavior, called social maturity at that time. 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). 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. 8. The social-cognitive processes and the approaches that are used to measure them can also inform and enrich the interviews that examiners conduct with individuals with mild mental retardation and other informants. 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). Other scales permit someone to help the person answer questions that cannot be answered without assistance. 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. 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). Behavior identification supporting assessment It is not evident that adaptive behavior scales efficiently differentiate among individuals with diverse disabilities that can be described as mild in degree (e.g., mild mental retardation, hyperactivity, specific learning disability) (Gresham & MacMillan, 1997; Zigler et al., 1984). 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. 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. 2. Grooming 2. 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. Some scales contain provisions for alternative items or alternative performance of items. Noncomparability of items may alter norms due to item wording that requires a higher developmental level of performance in the translated item. Such scales sample behaviors that are typically achieved at a range of ages and can indicate strengths and weaknesses in the ability to adapt. 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. 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). Unlike the area of social perception, there is no single instrument for assessing strategy generation in individuals with mental retardation. The committee does not recommend any specific list of instruments, but choices should be guided by the reviews of the available instruments in this chapter and the research literature on existing and new instruments. AAMR no longer differentiates, either qualitatively or quantitatively, differences in intellectual or adaptive functioning of individuals with mild, moderate, severe, and profound mental retardation. Student assessment results from formal, standardized assessment tools are often statistically based and can be very difficult for families to understand. The ABS-S:2 has excellent interrater reliability. Is adaptive behavior a set of abilities and skills useful in coping with environmental demands that are mastered by the individual? Vineland Adaptive Behavior Scales are a valid and reliable test to measure a person's adaptive level of functioning. 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. An adaptive behavior measure is a specific comprehensive assessment of independent living skills. Generally, adaptive. There are many reasons that can lead to maladaptive behavior. The Adaptive Behavior Inventory (ABIBrown & Leigh, 1986) was designed to reflect the ability of school-age youngsters to meet age-appropriate socio-cultural expectations for personal responsibility (Smith, 1989). (2000) mention the utility of adaptive behavior measures as components of multidimensional models of functioning and child psychopathology but did not include any adaptive behavior scales in an extensive listing of prominent measures that are currently used in psychological testing in schools. Checklists completed by teachers, parents, or other caregivers are often used to rate individuals' behavior for a broad variety of suspected conditions (e.g., mental retardation, autism, other pervasive developmental disorders, attention deficit disorder). (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. 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. Because Florida is a large and populous state with a culturally diverse population, it is likely that results can be generalized to the national population. Problems with assessing long term and short term adaptation One problem with assessments of adaptive behavior is that a behavior that appears adaptive in the short run can be maladaptive in the long run and vice versa. Furthermore, these limitations may be more noticeable in certain settings or circumstances than in others (Greenspan, 1999). Nine behavior domains measure personal independence and personal responsibility in daily living, including prevocational/vocational activity. Furthermore, behavioral, emotional, and social difficulties of the mildly mentally retarded . + Purpose of Adaptive Behavior Assessment: To confirm or establish a diagnosis To determine if the child is eligible for special education services To identify specific skills that need to be taught to the child for independent living To determine the child's level of functioning in daily tasks required to be successful in the home . 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. Jacobson & C.S. Careful analysis of the appropriateness of the item content and density of specific measures is crucial. Most adaptive behavior scales contain factors addressing interpersonal relationships or social skills, but they do not address overall social competence. 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). Avoiding danger 6. In adolescence and adult life: vocational and social responsibilities. Making a phone (or video) call is an example of adaptive behavior that changed over time. These measures also may be validly used, with repeated or periodic administrations, for assessment of changes in status. A strength of this scale is that teachers are asked to record when they estimate behaviors, so the resulting threat to reliability and validity can be appraised. In fact, semistructured interviews require the highest level of professional expertise, as the questioning and interpretation of answers requires a high level of training. 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. 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). Dr. Stephen Smagula, (Assistant Professor of Psychiatry), did his doctoral work in epidemiology, followed by postdoctoral training in geriatric psychiatry and sleep research. 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. Multidimensional or Unidimensional? 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. Observations of the individual in real-life, everyday situations 2. In fact, only one adaptive behavior test manual provides data that would be useful for answering this question. The result is an overidentification of skill limitations among minority children. 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. Bias refers to a consistent distortion of scores that is attributed to demographic factors, principally nonmodifiable personal characteristics such as age, gender, race, and ethnic or cultural membership. Thus, adaptive behavior scales have particular relevance in application with preschoolers and with teens, who are often participants in Supplemental Security Income (SSI) determinations or redeterminations. 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. ICD-10 views the relationship between intellectual functioning and adaptive behavior as causal, with deficits in adaptive behavior resulting from deficits in intellectual 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). 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. Consequently, several features must be balanced. When trained professionals use an interview format, the phrasing of items contained in the record booklet is not used. There are vast differences in how the third-party respondent reports on the adaptive behaviors of a client, particularly in the structure for the interview. 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. It also allows for reconciliation of ratings among these informants. The Adaptive Behavior: Street Survival Skills Questionnaire (SSSQLinkenhoker & McCarron, 1983) was designed to assess adaptive behavior in youth from age 9 years and adults with mild to moderate mental retardation. Indeed, this latter approach is consistent with guidance already noted from the Social Security Administration. By contrast, maladaptive behaviors. For example, they rarely employ the strategy of attempting to work out a mutually acceptable compromise solution in instances when one's interests conflict with another person's wishes (Hickson & Khemka, 1999; Hickson et al., 1998; Jenkinson & Nelms, 1994; Smith, 1986). 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. It is an important tool in eligibility consideration for students with mental handicaps and in the continual development of effective educational interventions. 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 use of a formal adaptive behavior measure allows . It appears to have good potential for assessing adaptive behavior for diagnostic purposes. 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. The disadvantage is that each clinician imposes his or her own subjective criteria, a process that threatens both the reliability and the validity of the assessment. In addition to the CBC, there are other instruments available to assess overt behavior, affect, or verbal statements consistent with the presence of mental or behavioral disorders among children and youth with mild mental retardation. 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). Washington (DC): National Academies Press (US); 2002. (1984), that adaptive behavior lacks a unifying theoretical foundation. Adaptive behaviors include real-life skills such as grooming, getting dressed, avoiding danger, safe food handling, following school rules, managing money, cleaning, and making friends. Generally, however, adaptive behavior measures will be less effective in fine-grained analysis and classification of such problems as specific motor disorders or communication disorders and deficiencies in concentration, persistence, or pace. It may, however, be useful for identifying some of the issues likely to arise in setting a specific numeric cutoff point. Because clinicians are encouraged to utilize multiple measures in diagnosis, these other measures may be useful in providing supplemental or complementary information. They also found that it was not the selection of the instrument that determined the number of factors. 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). 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. A relatively wide age range must be represented. Measures of behavioral functioning or responsiveness of children younger than 36 months have not been strengths of many adaptive behavior measures. These messages, known as social cues, consist of verbal and nonverbal stimuli, such as physical actions, words, facial expressions, tone of voice, and body language, which tell about others' behaviors, feelings, and intentions. Personal competence model. 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). Direct measures from target individuals involve presenting them with hypothetical situations and conducting direct observations. National Academies Press (US), Washington (DC). Food handling 7. The committee has identified several measures that would be useful in disability determination for mental retardation. The Vineland-3 is a standardized measure of adaptive behavior--the things that people do to function in their everyday lives. Reliability is good. The instrument must be appropriate to the age of the client and the client's approximate functioning level. Adaptive behavior scales were seldom used as components of assessment batteries. An average five-year-old, for example, would be expected to have adaptive behavior similar to that of other five-year-olds. 25. 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. 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.
