The Cognitive Difficulties Scale (CDS, McNair and Kahn, 1984) was used
to assess memory complaints in 1648 subjects devoid of severe medical
or psychiatric disorder. The subjects, aged 45-75 years, were recruit
ed when visiting their general practitioner. The CDS was well accepted
and showed a good and stable factorial structure. A weak correlation
was found between CDS score and the results of a short neuropsychologi
cal battery. A high CDS score was associated with advancing age, low e
ducational level, and psychological motives for visiting. A reduced 26
-item version is proposed to shorten the time required to fill in the
scale.
