A screening test of auditory comprehension for individuals with severe physical disability (PACST)

Tests of auditory comprehension are frequently unsuitable for patients with physically disabling conditions as they require abilities such as good vision or physical manipulation of test materials. A suitable test is required to assess patients who can only indicate 'yes' or 'no'. This has implications for enabling patients to make decisions about their care. A test consisting of 60 Yes-No questions was developed from a larger set tested on normals. A clinical trial was completed and the test found to be a useful tool. It allocates patients to three groups: normal, impaired and chance performance.
