Final answer:
The Social model calls for changes to the traditional medical approach by emphasizing societal barriers as the main contributors to disability, instead of individual physical limitations.
Step-by-step explanation:
The view that calls for changes to the traditional approach to diagnosing and treatment planning in People with Disabilities (PWD) is the Social model.
This model contrasts with the Medical model which views disability largely as a problem of the individual, directly caused by disease, trauma, or other health condition which requires medical treatment.
The Social model sees disability as created by social factors and the environment that does not accommodate for the diverse abilities of individuals. It suggests that societal barriers are the main contributing factor to disability, not one's physical limitations or conditions.
The Psychological model would focus on the individual's mindset and emotional responses to their disability, while the Holistic model would consider a range of factors including physical, emotional, social, and spiritual aspects in diagnosis and treatment.
Moreover, cultures approach mental illness and disability differently. For instance, in some communities, conditions such as schizophrenia might not be seen negatively but might have a role within cultural belief systems.
It's crucial, therefore, for health care providers to respect and understand various cultural perspectives and to integrate ethnomedicine with biomedicine, where appropriate, rather than overriding it.
