Antonio E. Puente, Ph.D. Mental Retardation and Adaptive Functioning North Carolina Advocates for Justice Raleigh, NC 05.21.10 In 1799, French physician Marc Itard worked with a child, “Victor”, in one of the first attempts to treat an individual with MR (Lane,1976). In 1846, Dr. Buckminster Brown visited the Hospital for the Cure and Education of Cretins (Switzerland) where cretins” were treated with gymnastic exercise and isolation from population (Brown,1847). In the past, the following terms were used to describe or refer to MR individuals as diagnostic and legal terminology (Volkmar & Dykens, 2002): ◦ ◦ ◦ ◦ Idiots Fools Morons Imbiciles Change from what a person cannot do to what a person can do. There is a greater focus on inclusion instead of exclusion. Treatment and assistance can help MR individuals to function in society MR individuals is associated with cognitive deficits (IQ ≤ 70) and deficits in adaptive skills. There are multiple definitions of MR with overlap. ◦ ◦ ◦ ◦ ◦ World Health Organization (1996). DSM-IV-TR (APA, 2000). AAMR: 10th Edition (Luckasson et al., 2002). AAIDD: 11th Edition (AAID, 2010). Social Security Administration (2010) According to the ICD-10 Guide For Mental Retardation (1996): “Mental retardation is a condition of arrested or incomplete development of the mind, which is especially characterized by impairment of skills manifested during the developmental period, which contribute to the overall level of intelligence, i.e., cognitive, language, motor, and social abilities” (p.9). Source: http://whqlibdoc.who.int/hq/1996/WHO_MNH_96.3.pdf “This disorder is characterized by significantly subaverage intellectual functioning (an IQ of approximately 70 or below) with onset before age 18 years and concurrent deficits or impairments in adaptive functioning. Separate codes are provided for Mild, Moderate, Severe, and Profound Mental Retardation, and for Mental Retardation, Severity Unspecified” (p.39). “Mental retardation is a disability characterized by significant limitations both in intellectual functioning and in adaptive behavior as expressed in conceptual, social, practical adaptive skills. The disability originates before age 18” (p.18). The term “Intellectual disability” is synonymous & generally replacing the term “mental retardation”. According to the President’s Committee for People with Intellectual Disabilities: ◦ Estimated of seven to eight million Americans experience some kind of ID ◦ Affect 10% of the families in the U.S. Source: http://www.aaidd.org/content_96.cfm?navID=20 According to AAIDD: “Intellectual disability is a disability characterized by significant limitations both in intellectual functioning and in adaptive behavior, which covers many everyday social and practical skills. This disability originates before the age of 18” Source: http://www.aaidd.org/content_100.cfm?navID=21 Refers to general mental capacity (learning, reasoning, problem solving, etc). Intellectual functioning usually measured with IQ test scores. Usually, IQ score between 70 & 75 indicates limitation in intellectual functioningborderline. Source: http://www.aaidd.org/content_100.cfm?navID=21 Adaptive behavior includes three skills: Conceptual skills ◦ Language & literacy; money, time, and number concepts, & self-direction. Social Skills ◦ Interpersonal skills, social responsibility, selfesteem, gullibility, social problem solving, ability to follow rules/laws, etc. Practical skills ◦ daily living activities, personal care, occupational skills, healthcare, use of $, travel/transportation, etc. ◦ Source: http://www.aaidd.org/content_100.cfm?navID=21 Used for death penalty cases Based on Supreme Court decision – Atkins State based Two criteria; ◦ Quantitative ◦ Qualitative “Significantly subaverage general intellectual functioning with deficits in adaptive functioning initially manifested during the developmental period, i.e., the evidence demonstrates or supports onset of the impairment before age 22”.

Marked difficulties in maintaining social functioning; or ◦ 3. Marked difficulties in maintaining concentration, persistence, or pace; or ◦ 4. Repeated episodes of decompensation, each of extended duration Source: http://www.socialsecurity.gov/disability/professionals/bluebook/12.00-MentalDisordersAdult.htm#12.05%20Mental%20Retardation Concentration, persistence or pace refers to the ability to maintain focused attention & concentration sufficiently long to permit the timely & appropriate task completion commonly found in work settings. Limitations in concentration, persistence, or pace may also be reflected by limitations in other settings (i.e., social settings).

Source: Standards for Educational and Psychological Testing (1999) The definition of disability under SS is different than other programs. "Disability" under SS is based on inability to work. Considered disabled if: ◦ Cannot do work as before; ◦ Cannot adjust to other work because of medical condition(s); and ◦ Disability has lasted or is expected to last for at least one year or to result in death.
