This is the third in a series of perspective articles (Schalock et al., 2007; Wehmeyer et al., 2008) from the Terminology and Classification Committee of the American Association on Intellectual and Developmental Disabilities (AAIDD). The purpose of these articles is to share our thoughts on critical issues associated with terminology, definition, and classification in the field of intellectual disability and to seek input from the field as we prepare the 11th edition of AAIDD's Diagnosis, Classification, and System of Supports Manual (the working title). In the first article (Schalock et al., 2007), we explained the reasons for shifting from the term mental retardation to intellectual disability. Although the two terms cover the same population of individuals, we concluded that intellectual disability was the better term because itIn the second article (Wehmeyer et al., 2008), we distinguished between operational and constitutive definitions of intellectual disability and discussed their application to understanding the construct underlying the term intellectual disability. The primary function of an operational definition is to assure consistency among diagnosticians by setting parameters for observing and recording evidence of the disability (Wehmeyer et al., 2008). We supported the continued use of the operational definition of intellectual disability (formerly mental retardation) from the 2002 manual (Luckasson et al., p. 1): “[Intellectual disability is] characterized by significant limitations both in intellectual functioning and in adaptive behavior as expressed in conceptual, social, and practical adaptive skills. This disability originates before age 18.”The operational variables included in AAIDD definitions have not changed significantly in 50 years (Schalock et al., 2007). Operational criteria for diagnosis have been generally consistent for the past 35 years, when the IQ criterion was changed from one to two standard deviations (Grossman, 1973). However, the construct underlying the term intellectual disability (and, thus, the constitutive definition of intellectual disability) has changed significantly over the last 2 decades due to the impact of the social–ecological model of disability (Institute of Medicine, 1991; Luckasson et al., 1992, 2002; WHO, 2001). In this model, intellectual disability is understood as a multidimensional state of human functioning in relation to environmental demands.This article focuses on supports and support needs, as they pertain to persons with intellectual disability, and closely related developmental disabilities. Definitions of each are as follows:This article is organized into five sections: (a) distinguishing the concept of supports from the construct of support needs; (b) conceptualizing supports as the bridge between “what is” (i.e., a state of incongruence due to a mismatch between personal competency and environmental demands) and “what can be” (a life with meaningful activities and positive personal outcomes); (c) considering support needs within a model of human functioning; (d) recommending an assessment and planning process to guide planning teams (and organizations) when developing and implementing individualized support plans; and (e) comparing and contrasting support planning with other planning approaches in the field of intellectual disability and related developmental disabilities.Supports are resources and strategies that enhance human functioning (Luckasson et al., 2002). Although this definition was developed with people with intellectual disability in mind, it is clear that everyone uses supports. The 17th-century theologian John Donne wrote, “No man is an island” (as cited in Jokinen, 2006) to convey the fundamental truth that human beings do not thrive in isolation from others. We live in an interdependent world and everyone needs a variety of supports to function on a daily basis. However, the types and intensity of supports needed by people with intellectual disability are different from those needed by most other people.Support needs, as we use it and position it within our understanding of intellectual disability, is a psychological construct referring to the pattern and intensity of support a person requires to participate in activities associated with normative human functioning. Multiple psychological constructs have been identified regarding both “states” and “traits” of humans. For example, anxiety, intelligence, happiness, and morality are all psychological constructs on which there are extreme points (e.g., euphoric vs. depressed) as well as many points in between, just like the construct of support needs. The support needs construct is based on the premise that human functioning is influenced by the extent of congruence between individual capacity and the environments in which that individual is expected to function. Addressing this congruence (i.e., ensuring person–environment fit) involves understanding the multiple factors that shape human performance, determining the profile and intensity of needed supports for a particular person, and providing the supports necessary to enhance human functioning.The concept of need generally refers to a condition characterized by the absence of some requisite necessity. Within professional literature pertaining to health, the concept of need has traditionally referred to a condition characterized as “a disturbance in health and well-being” (Donabedian, 1973, p. 62). Within psychology, need is defined as “what is necessary for an organism's health and well being” (Harré & Lamb, 1988, p. 409) or a motivated state resulting from “a feeling of unfulfillment or deprivation in the biological system…evidenced by a drive to complete such a lack” (Colman, 2001, p. 631). As discussed by Thompson and colleagues (Thompson et al., 2002, 2004b), support needs are identified on the basis of input from the individual and other respondents. Global (i.e., overall) support needs can be understood in at least four distinct ways:We do not see a person's support needs as necessarily or exclusively reflecting a disturbance of human capacity (although disability certainly may result in a disturbance of human capacity); rather, the person's support needs reflect a limitation in human functioning as a result of either personal capacity or the context in which the person is functioning. Like other psychological constructs, the level of a person's support needs (like the level of a person's motivation or shyness) is inferred and not directly observable. Moreover, an individual's support needs can be measured with varying degrees of accuracy by self-report and other report indicators of the intensity of support needs, such as is accomplished using the Supports Intensity Scale (Thompson et al., 2004a). To be clear, we see the support needs construct as reflecting more of an enduring characteristic of the person than simply a point-in-time description of the need for a particular type of support. People with intellectual disability are people who require the provision of ongoing, extraordinary (when compared with their nondisabled peers) patterns of support. Providing supports to people with intellectual disability enables their functioning in typical life activities in mainstream settings but does not eliminate the possibility that they will continue to need ongoing supports. Put another way, if supports were removed, people with intellectual disability would not be able to function as successfully in typical activities and settings.A major implication of conceptualizing intellectual disability as a state of functioning instead of an inherent trait is that the person–environment mismatch is addressed. The focus is not solely on “fixing” the individual. This implication is shown in the supports model depicted in Figure 1. First, in this model, a mismatch between personal competency and environmental demands results in support needs that necessitate particular types and intensities of individualized supports. Second, to the extent that these individualized supports are based on thoughtful planning and application, it is more likely that they will lead to improved human functioning and personal outcomes. As a bridge between “what is” and “what can be,” the focus of educational and habilitation service systems shift to understanding people by their types and intensity of support needs instead of by their deficits. Although there is a reciprocal relationship between impairments and support needs in that greater personal limitations will almost always be associated with more intense support needs, a focus on reducing the mismatch between peoples' competencies and the environmental requirements where they function, rather than a focus on deficits, is more likely to reveal supports that enhance personal outcomes.Figure 1 also illustrates two related global functions of individualized supports. The first function addresses the discrepancy between what a person is not able to do in different settings and activities and what changes–additions make that person's participation possible (e.g., promote human functioning). The second function of individualized supports focuses on enhancing personal outcomes by improving human functioning. Both functions need to be thoughtfully aligned.Sometimes, planning teams focus solely on what individuals can and cannot do in a variety of settings and, thus, arrange supports to empower individuals to do more things. Although this type of planning may lead to an individual's improved functioning, that individual's personal outcomes may not be significantly enhanced. Such planning may expand the activities available to the person and may even increase participation by the individual, but if these activities are not based on the person's preferences and priorities, any improvement in personal outcomes may be negligible. Equally misguided would be a focus only on personal priorities and preferences without thoughtfully considering the gaps between a person's competence and his or her environmental demands. This approach to planning increases the risk that supports will be arbitrarily applied. For example, an individual may want to live in his or her own home in the community, but may need some support that peers without disabilities will not need due to specific safety related concerns. A “throw in everything plus the kitchen sink” approach to supporting the individual might involve supplying staff inside the home 24 hr a day, 7 days a week who do all the cooking, cleaning, transporting, and so forth. Such excessive support provisions will not enhance the life experiences of the individual and will certainly result in wasting finite resources. Therefore, it is important to thoughtfully analyze and align both personal priorities and areas of need when planning and delivering supports.Supports are resources and strategies that enhance human functioning (Luckasson et al., 2002). Human functioning is enhanced when the person–environmental mismatch is reduced and personal outcomes are improved. Because human functioning is multidimensional, considering supports as a means to improve human functioning provides a structure for thinking about more specific functions of support provision.Human performance technology (HPT) theorists posit that human functioning results from interactions between a person's behavior and his or her environment (Gilbert, 1978). For example, Wile (1996), who created an HPT model by synthesizing five other leading HPT models, suggested that human performance is influenced by the following seven elements: organizational systems, incentives, cognitive supports, tools, physical environment, skills–knowledge, and inherent ability. Examples of support that correspond to each of Wile's human performance elements are listed in Table 1. Wile noted that some of these elements are external to the person (Elements 1–5), whereas others (Elements 6–7) are internal.Wile's (1996) seven elements are interdependent in terms of human performance and, more accurately, should be thought of as being cumulative. Therefore, from a supports perspective, solving a problem for any single element may be of limited value if problems with the other elements are ignored. As Edyburn (2000) pointed out when relating Wile's model to decision making in the area of assistive technology, getting a tool (Element 4) to improve performance would have a negligible impact if the person lacked motivation (Element 2) to be productive on the task for which the tool was to be used. Based on Wile's HTP model, supports should not be delivered to address discrete life activities or separate events, or be based on specific support individuals (e.g., job coaches, teachers). Rather, systems of support should be conceptualized where multiple aspects of human performance are considered in regard to multiple settings.It is not difficult to envision what a system of support would entail when considering the human performance elements in Table 1. Take the case of a man with intellectual disability working on a community job. The man in our hypothetical example was hired through an on-the-job-training (OJT) program offered by a state vocational rehabilitation (VR) agency (Element 1: Organizational Systems). This person was motivated to do well on the job because of opportunities for and (Element but from on specific job that to be difficult (Element In this assistive to more (Element and needed to have the physical environment to complete job (Element task of aspects of the job were developed and to (Element and was to a job that was consistent with his and personal This example illustrates each element of human performance was through a system of supports, the a to be on his implication of Wile's (1996) model is the supports at the organizational Although is not considered an individualized it is that and can have on the and of the Disabilities of and on opportunities to with disabilities in the to it was in many to a with needs to a Although and state as well as would be listed as distinct supports on individualized it is important to the that and have on the and of supports that are are a of resources and strategies that enhance human functioning. individual will need all of the types of supports that are support needs both and teams are in the position to the types of supports that people As shown in Figure we a process for (a) what the person most and needs to (b) the of support a person will require to what or most and needs to (c) developing an to and supports, (d) and the and (e) personal outcomes.
