Developmental Disabilities: Disorders in which there is a delay in development based on that expected for a given age level or stage of development. These impairments or disabilities originate before age 18, may be expected to continue indefinitely, and constitute a substantial impairment. Biological and nonbiological factors are involved in these disorders. (From American Psychiatric Glossary, 6th ed)Intellectual Disability: Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range. (from Joynt, Clinical Neurology, 1992, Ch55, p28)Education of Intellectually Disabled: The teaching or training of those individuals with subnormal intellectual functioning.Mentally Disabled Persons: Persons diagnosed as having significantly lower than average intelligence and considerable problems in adapting to everyday life or lacking independence in regard to activities of daily living.Disability Evaluation: Determination of the degree of a physical, mental, or emotional handicap. The diagnosis is applied to legal qualification for benefits and income under disability insurance and to eligibility for Social Security and workmen's compensation benefits.Dental Care for Disabled: Dental care for the emotionally, mentally, or physically disabled patient. It does not include dental care for the chronically ill ( = DENTAL CARE FOR CHRONICALLY ILL).Disabled Persons: Persons with physical or mental disabilities that affect or limit their activities of daily living and that may require special accommodations.Autistic Disorder: A disorder beginning in childhood. It is marked by the presence of markedly abnormal or impaired development in social interaction and communication and a markedly restricted repertoire of activity and interest. Manifestations of the disorder vary greatly depending on the developmental level and chronological age of the individual. (DSM-V)Disabled Children: Children with mental or physical disabilities that interfere with usual activities of daily living and that may require accommodation or intervention.Group Homes: Housing for groups of patients, children, or others who need or desire emotional or physical support. They are usually established as planned, single housekeeping units in residential dwellings that provide care and supervision for small groups of residents, who, although unrelated, live together as a family.Token Economy: A practice whereby tokens representing money, toys, candy, etc., are given as secondary reinforcers contingent upon certain desired behaviors or performances.Reinforcement (Psychology): The strengthening of a conditioned response.Behavior Therapy: The application of modern theories of learning and conditioning in the treatment of behavior disorders.Self-Injurious Behavior: Behavior in which persons hurt or harm themselves without the motive of suicide or of sexual deviation.Child Development Disorders, Pervasive: Severe distortions in the development of many basic psychological functions that are not normal for any stage in development.

(from APA, DSM-IV, 1994).Cerebral Palsy: A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)Language Development Disorders: Conditions characterized by language abilities (comprehension and expression of speech and writing) that are below the expected level for a given age, generally in the absence of an intellectual impairment. These conditions may be associated with DEAFNESS; BRAIN DISEASES; MENTAL DISORDERS; or environmental factors.Employment, Supported: Paid work for mentally or physically disabled persons, taking place in regular or normal work settings. It may be competitive employment (work that pays minimum wage) or employment with subminimal wages in individualized or group placement situations. It is intended for persons with severe disabilities who require a range of support services to maintain employment. Supported employment differs from SHELTERED WORKSHOPS in that work in the latter takes place in a controlled working environment. Federal regulations are authorized and administered by the U.S. Department of Education, Office of Special Education and Rehabilitative Services.Insurance, Disability: Insurance designed to compensate persons who lose wages because of illness or injury; insurance providing periodic payments that partially replace lost wages, salary, or other income when the insured is unable to work because of illness, injury, or disease. Individual and group disability insurance are two types of such coverage.

They may be influenced by physiological drives or by external stimuli.Conditioning, Operant: Learning situations in which the sequence responses of the subject are instrumental in producing reinforcement. When the correct response occurs, which involves the selection from among a repertoire of responses, the subject is immediately reinforced.Chronic Disease: Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care.

Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).Risk Factors: An aspect of personal behavior or lifestyle, environmental exposure, or inborn or inherited characteristic, which, on the basis of epidemiologic evidence, is known to be associated with a health-related condition considered important to prevent.Social Security: Government sponsored social insurance programs.Attitude to Health: Public attitudes toward health, disease, and the medical care system.Pain Measurement: Scales, questionnaires, tests, and other methods used to assess pain severity and duration in patients or experimental animals to aid in diagnosis, therapy, and physiological studies.Retrospective Studies: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past.
