[Snijders-Oomen Nonverbal Intelligence Test: useful for the elderly?].
The feasibility of the SON-R 5 1/2-17, a non-verbal intelligence test for deaf children, was investigated in a group of older adults, with a view to the future use of the test in older neurological patients. In a group of 58 healthy elderly persons intelligence was measured with the SON, the Raven Progressive Matrices and a Dutch reading test. The subjects were also asked for their subjective judgements of the tests. The SON-R 5 1/2-17 appears to be a user-friendly test. The high correlations between the subtests, and between the SON and other measures of intelligence suggest that the SON is a valid test for measuring fluid intelligence in elderly persons. The existing norms are not suitable when the SON is used in elderly people, new norms for adults should therefore be developed.
