Sammanfattning
Background According to the Swedish National Board of Health and Welfare, structured
assessment of function and activity has high priority when evaluating suspected cognitive
impairment or dementia. Aim/objectives The aim was to develop and psychometrically test an
instrument to measure the ability to perform activities of daily living tasks in patients with suspected
cognitive impairment. Material and methods The Cognitive Impairment in Daily Life (CID) instrument
(for self-reported and informant-based assessments) has been developed in several phases. Content
validity was achieved through five expert panels using a Content Validity Index (CVI). The content
was tested further in a pilot study of 49 patients and 49 relatives from primary care or a specialist
memory clinic. Results Content validity was good with a CVI index of 0.83. All patients considered
that the included activities were relevant to them and reflected the difficulties they were experiencing.
Most relatives considered the activities included in the instrument as adequate and captured the
patients’ difficulties in daily life. Some adjustments of the tasks and scale were suggested and these
were implicated after each phase. In general, relatives reported that patients had more difficulties
performing the activities than the patients reported themselves. Conclusion The CID instrument
seems promising in terms of content validity. Further testing of reliability and construct validity is
ongoing.
