Why is adaptive behavior difficult to measure

In the 19th century, mental retardation was recognized principally in terms of a number of factors that included awareness and understanding of surroundings, ability to engage in regular economic and social life, dependence on others, the ability to maintain one's basic health and safety, and individual responsibility Brockley, Today, fulfillment of these personal and social responsibilities, as well as the performance of many other culturally typical behaviors and roles, constitutes adaptive behavior.

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, These practices persisted over that century because of the absence of standardized assessment procedures.

And many individuals who would currently be considered to have mild mental retardation were not included in these early definitions. 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.

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, ; Wilbur, 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.

Chapter 3 provides details on the development of intelligence assessment. Alternative measures to complement intelligence measures began to appear as early as Edger Doll produced form board speeded performance tests, which were analogues to everyday vocational tasks. During the s, Doll, Kuhlmann, and Porteus sought to develop assessment practices consistent with a definition of mental retardation that emphasized adaptive behavior and social competence.

Their work in this area sparked broadened interest in measurement of adaptive behavior among practitioners serving people with mental retardation Doll, ; Kuhlman, ; Porteus, ; Scheerenberger, Doll emerged as a leader in the development of a psychometric measure of adaptive behavior, called social maturity at that time.

His work emphasized social inadequacy due to low intelligence that was developmentally arrested as a cardinal indication of mental retardation Doll, a, p. Doll objected to the definition of mental retardation in terms of mental age, which had proven problematic in IQ testing because it resulted in classification of a significant proportion of the population.

The VSMS, which measured performance of everyday activities, was the primary measure used to assess adaptive behavior, social competence, or social maturity for several decades.

One concern that emerged over time was that it was developed and normed for use with children and youth. It did not cover adults and had a limited range of items tapping community living skills Scheerenberger, The assessment of adaptive behavior became a formal part of the diagnostic nomenclature for mental retardation with the publication of the manual of the American Association of Mental Deficiency Heber,distributed in The manual Heber, discussed adaptive behavior with respect to maturation, learning, and social adjustment.

The manual characterized the tasks or activities encompassed by adaptive behavior and, plausibly social competence as: In infancy and early childhood: During the s, a wider variety of adaptive behavior measures was developed and disseminated e.

Measures developed in the s have typically been updated in subsequent editions with enhanced psychometric characteristics and scoring e. Over the past 25 years there has also been further refinement of the parameters and structure of tests of adaptive behavior and social competence.

Finally, the difficulties and complexities of differentiating mild mental retardation from its absence or from other disabling conditions e.

Differing Conceptualizations In Chapter 1 we summarized the history of definitions of mental retardation and discussed their relevance to the Social Security Administration's definition. At first glance, current definitions seem to be quite similar; however, there are subtle differences in the conceptualization of adaptive behavior that may affect the outcomes of diagnostic decisions for individuals with mental retardation, particularly those in the mild range.

The definition speaks to the presence of significant limitations in intellectual functioning and significant limitations in adaptive behavior, which exist concurrently.

In this definition, the order of the constructs can be switched without affecting the validity of the definition.

The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition DSM-IVpublished by the American Psychiatric Associationdefinition 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.

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.

Furthermore, issues are raised about the degree to which existing instruments are able to take into account the cultural context in assessing an individual's adaptive behavior. For example, adaptive behavior is defined in terms of effectively coping with common life demands and the ability to meet the standards of personal independence for a particular age group with a specific sociocultural background.

No mention is made of the degree of severity of adaptive deficits for each of these levels, nor of the number or types of impaired adaptive behavior domains at each level.

ICD views the relationship between intellectual functioning and adaptive behavior as causal, with deficits in adaptive behavior resulting from deficits in intellectual functioning.

In their most recent classification system American Association on Mental Retardation,AAMR defines mental retardation as subaverage intellectual functioning existing concurrently with limitations in adaptive skills.

These limitations in adaptive skills are operationally defined as limitations in two or more of ten applicable adaptive skill areas e. AAMR no longer differentiates, either qualitatively or quantitatively, differences in intellectual or adaptive functioning of individuals with mild, moderate, severe, and profound mental retardation.

Instead, they differentiate individuals with mental retardation based on the supports they need. The result is that the unique aspects and characterization of individuals with mild mental retardation are no longer the basis for differentiating them from more moderately and severely involved individuals.

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.

Among these four definitions, there is little variation in the intelligence construct for individuals with mental retardation.Adaptive behavior refers to behavior that enables a person (usually used in the context of children) to get along in his or her environment with greatest success and least conflict with others.

This is a term used in the areas of psychology and special education. Explain why adaptive behavior difficult to measure. Adaptive behavior measurement is difficult because of each individual’s competency to adjust socially. Each group’s situation may be different and many other things come into play that effect adaptive behavior%(6).

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.

A number of people with intellectual disability are mildly affected, making the disability difficult to recognize without visual cues. Intellectual disability is diagnosed through the use of standardized tests of intelligence and adaptive behavior.
