This assessment ideally informs decisions concerning need for services, the expense that accompanies sponsorship, and the provision of assistive equipment that can enhance quality of life. Psychological assessment is of particular importance during this era when many health care delivery systems limit access to care, which in turn can result in higher costs associated with the subsequent treatment of preventable conditions. Unfortunately, many psychologists are not trained to face the issues inherent in the assessment of persons with physical disabilities. These problems exist despite the original mandates of the Rehabilitation Act of 1973 for psychologists to have the rudimentary skills to conduct informed assessments of people with disabilities.
