Agreement…
There is value in understanding the nature of different kinds of disabilities and identifying disabilities so that beneficial interventions and services may be provided
Disagreement
The process by which we classify and label individuals in our pursuit to provide effective treatments
Classification
A process that separates individuals into groups that share common characteristics
SO….
If an individual is a member of a particular class or category, what is known about the class designation will give information about that individual
Purpose of classification
To determine eligibility for services and entitlements; to make diagnoses; to plan, implement, and evaluate intervention services; and to conduct research
Classification to Determine Eligibility for Services
The Individuals with Disabilities Education Act (IDEA, PL 101-476) specifies those disabilities that entitle children to special education and related services ■Autism ■Deaf-blindness ■Deafness ■Developmental delay ■Emotional disturbance ■Hearing impairment ■Intellectual disability ■Multiple disabilities ■Orthopedic impairment ■Other health impairment ■Specific learning disability ■Speech or language impairment ■Traumatic brain injury ■Visual impairment, including blindness
“Autism” eligibility category
…means a developmental disability significantly affecting verbal and nonverbal communication and social interaction, generally evident before age three, that adversely affects a child’s educational performance. Other characteristics often associated with autism are engaging in repetitive activities and stereotyped movements, resistance to environmental change or change in daily routines, and unusual responses to sensory experiences. The term autism does not apply if the child’s educational performance is adversely affected primarily because the child has an emotional disturbance, as defined in #5 below.
A child who shows the characteristics of autism after age 3 could be diagnosed as having autism if the criteria above are satisfied.
This categorical approach results in “all in” or “all out” outcomes
Either a child does or does not have a particular disability
Conversely
A “dimensional“ approach groups individuals according to constructs or dimensions
Examples: Borderline personality disorder, mood disorder
This approach could allow inclusion of individuals with serious problems, but who do not meet full criteria for category membership
Classification by Etiology
The “what” Grouping individuals with disabilities
according to the causes of the disabilities
Classification by Etiology
The “why” Durkin and Stein (1996) suggest that
etiological classification is useful for planning primary prevention, understanding the nature of a disability, conducting epidemiological research and providing information to families
The scientific study of mental retardation is often based on etiological classification…
Organic Versus Familial Retardation
Zigler et al. (1986) propose 2 groups of individuals with mental retardation:
Organic etiology
Non-organic etiology
The “organic” etiology
IQ scores below 50 Physical stigmata Siblings with typical cognitive
development High prevalence of physical conditions
such as epilepsy or cerebral palsy
All socioeconomic classes represented
The “non-organic” etiology
The “familial” group IQ scores between 50 and 71 Typical physical appearance At least one family member with lower
intelligence or mental retardation Families are generally of lower socioeconomic
status
No demonstrable organic cause
Perspective: Recent years
Mental retardation is the result of complex, often interactive influences
May be an interaction of adverse biological, environmental, and behavioral influences on health and development
Syndromes
Down Syndrome Genetic cause Generally identified at (or before) birth Good deal of knowledge regarding associated
medical problems, prognosis, and treatments that optimize development
Classification by etiology has proven beneficial in this case
Classification by Levels of Support
In 1992, the AAMR (American Association on Mental Retardation ) revised the definition of mental retardation
The new definition eliminated previous levels of measured intelligence and replaced it with an individuals level of need for intensive supports to function in daily life
What are the potential problems with this?
Operationally defining the definition Lack of reliable or valid measures for
determining support intensities Poor applicability of specified adaptive
skill areas to children Potential to confuse intensities of
supports with previously specified degrees of intellectual disability
The 2002 AAMR Definition
A “happy medium”
Classification may be based on intensities of supports, etiology, IQ ranges, levels of adaptive behavior, or other factors
Replaces the 10 adaptive skills areas with 3 more general areas Conceptual Social practical
Classification by Levels of Measured Intelligence
2002 AAMR definition permits classification by IQ severity levels Mild Moderate Severe Profound
Each level of severity is associated with different developmental trajectories, and different adult outcomes
This information assists with planning interventions
International Classification Systems
In an attempt to create increased international consistency, the World Health Organization developed two classification systems:
Classification of Mental and Behavioral Disorders: Diagnostic Criteria for Research (ICD-10)
International Classification of Functioning, Disability, and Health
International Classification Systems
ICD- 10 is conceptualized in terms of interaction between person and environment NOT as a fixed trait
Criticisms: this functional orientation is likely difficult when one considers differences between countries and cultures
Identification and Diagnosis
Where classification emphasizes characteristics of groups…
Diagnosis focuses on characteristics of particular individuals…
Resulting in a label(s)
Early Identification and Diagnosis
There are legal mandates and funding incentives to identify children’s developmental problems prior to age 3
Early intervention renders preferred outcomes in school, home and community settings
Early Identification and Diagnosis
Some disabilities are evident from infancy
Other disabilities do not become evident until certain developmental milestones fail to be achieved
Many children with autism are now identified prior to age 3
Early Identification and Diagnosis
Benefits child outcomes
Benefits parent outcomes Decreased parental stress Improved family interactions
Diagnostic Guidelines
General use of diagnostic criteria DSM-IV (1994), DSM-IV-TR (2000) Subjective clinical judgement in deciding
whether or not the symptoms observed meet diagnostic criteria
Some criteria are not suited for very young children…
Diagnostic Guidelines
In an effort to establish and present more age appropriate guidelines, the National Center of Clinical Infant Programs developed the
Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (birth-3)
Checklists and Screening Tools
The Checklist for Autism in Toddlers (CHAT; Baron-Cohen, Allen, & Gillberg, 1992)
The Childhood Autism Rating Scale (CARS; Schopler, Reicher & Renner, 1988)
The Pre-Linguistic Autism Diagnostic Observation Schedule (PL-ADOS; DiLavore, Lord & Rutter, 1995)
The Autism Diagnostic Interview- Revised (ADI-R; Rutter, Lord & LeCouteur, 1995)
The Communication and Symbolic Behavior Scales (CSBS; Wetherby & Prizant, 1993)
Labels
The outcome of both diagnostic processes and classification for services (the educational system) often result in LABELS
Labels
Can be stigmatizing
Criticisms of the biases of IQ tests especially for minority groups, individuals of low socioeconomic status
Changing Labels?
Reluctance to use labels may result in a shift from one label perceived as less preferable to one that may be more socially acceptable
Data from the U.S. Department of Education (1999) indicate that children served as “learning disabled” increased 202% from 1994 to 1997; those served as “mentally retarded” decreased 38%
Changing Labels
Alternative terminology has been suggested for “mental retardation” including
General learning disorder Intellectual disability Cognitive-adaptive disability
The Effects of Labeling
A direct relationship between labeling and self concept has not been evidenced Some children experience improved self
esteem when they access appropriate services
But what about teacher perception and expectations?!?!
Effects of Labeling
Smith (1980) conducted a meta analysis of 47 studies and found full support for formation of expectations, partial support for the differential effects of labels on teacher behavior and student achievement, and little support for the effects of that process on student ability
Brophy (1983) reviewed the research on self fulfilling prophecy and concluded that teachers revise their expectations as they gain new information about their students
Sattler (2001) found that although teachers may form initial opinions and establish early expectations about their students, they revise their expectations based upon the students performance
BUT what about peer attitudes?!?!
Effects of Labeling
Studies found that labels had little impact on the attitudes of peers toward their classmates with disabilities
Some research supports a protective effect
Non-Labeling
There have been no benefits found to avoiding formal labels
Students had less favorable attitudes toward children with disabilities (mental retardation) who were not labeled
Non-labeling often results in a failure to provide appropriate services and poor outcomes
Permanence of Labels
“once labeled…always labeled”
Often it is the nature of the disability and not the label that renders life long obstacles
Our goals should focus on optimizing treatment opportunities rather than pursuit of a “cure”
Professionals’ Reluctance to Label
Some professionals may be reluctant to use the diagnostic labels, or discuss the nature of the disability May use vague terminology
Studies support that parent want to know the truth about their children’s disabilities
Benefits to Labeling
Professionals and families may formulate appropriate expectations
Access, plan and implement appropriate interventions
Support families in accessing resources, community groups, adovocacy
Conclusion
Although classification, diagnostics, and labeling will likely be a source of controversy for some time
It is essential that professionals and parent base their opinions on empirical data rather than personal ideology
Classification, diagnosis and labels can assist families in accessing appropriate supports and services
