What is the medical model?
- Defines disability in terms of biological impairments
- Disability viewed as a problem that is caused by medically-diagnosed genetic disorders, disease, trauma, or other health conditions
- Disability is treated as a biological problem that diminishes quality of life
- Disability is viewed as needing to be treated with professional medical care.
What are the strengths of the medical model?
- Acknowledges biological condition that places an individual at a disadvantage compared to the majority of the population
- Clearly-defined set of criteria helps inform decisions about who receives government assistance
- Helps medical professionals make important decisions in terms of treatment.
What are the weaknesses of the medical model?
- Focuses exclusively on the biology of the person - overlooks the impact of the design decisions in our social environment
- Assigns disability as a characteristic of an individual person - stigmatizes person as different or less than. This causes psychological harm.
- People who do not fit within the clearly-defined definitions may be denied benefits they need. Definitions may be too narrow and exclusive.
- Having to prove a disability adds bureaucracy to their lives.
- Having to provide your disability can be dehumanizing.
What is the social model?
- Direct response to the medical model
- Society creates disabling conditions. “Disability” is an avoidable condition caused by poor design
- Emphasizes human rights of people with disabilities to participate in society in meaningful ways
What are the strengths of the social model?
- Empowers people with disabilities by removing the stigma often associated with physical impairments
- Expectation is that society creates inclusive environments - not that people with disabilities need to have a lower quality of life because they do not conform to “normal” expectations
- We get better designs for everyone. Empowers designers of physical and virtual environments to think broadly about usability for all kinds of humans
What are the weaknesses of the social model?
- Can de-emphasize the physical reality of a disability too much. Disability is an important part of identity and should not be minimized.
- Accepting and “owning” one’s disability can be very healthy from an emotional and psychological perspective
