[Assessment of depressive symptoms in old visually-impaired people: a study of the Geriatric Depression Scale].
This study has two main purposes: (a) to assess the functioning of the Geriatric Depression Scale in its Spanish version in old visually-impaired people, and (b) to assess the relevance of measuring depressive symptoms within a comprehensive assessment of psychological adjustment related to vision impairment in that population. Respondents were 329 people affiliated to the ONCE who were a representative sample of the target population. The assessment of the first goal let us to establish two cut-off points, and led to new methodological developments that combine Item Response Theory and Classical Test Theory. The results indicated that the scale is particularly useful in the target population and that it is very relevant in the assessment of psychological adjustment related to visual impairment in old people.
