[Identification of items for creating a questionnaire for the assessment of instrumental activities of daily living (IADL) in elderly patients].

OBJECTIVE

To identify items to design a questionnaire to assess IADL in the elderly in the community.

DESIGN

Delphi study.

LOCATION

Community setting, primary health care.

PARTICIPANTS

Fifty seven multidisciplinary experts (family doctors, geriatricians, physiotherapists, social workers, male nurses) who are members of the Spanish Society of Family and Community Medicine or the Spanish Geriatrics and Gerontology Society.

METHODS

Three consecutive questions sent via e-mail or fax. First: what items you would take into account in a questionnaire to assess IADL in the elderly? Second: out of the groupings select 10 you consider to be of special relevance? Third: among the 14 more most selected items, select, by scoring from 1 to 10, the ones you consider more important? In the end we obtained the 10 items to include in the questionnaire according to their scores.

RESULTS

Thirty experts answered the 3 mailings. The 53 initial proposals were grouped into 24 items. In the end we obtained the following selection (from higher to lower score): dealing with medication, use of the telephone, housework, handling money, walking outside the home, security measures and risk avoidance, shopping, dealing with doors and keys, transport use, and means of social contact.

CONCLUSIONS

Only 2 items could have gender influence (in contrast to other questionnaires), as "shopping" does not refer only to the household ones and "housework" also includes activities carried out by males. The most important items are "dealing with medication" (due to the high prevalence of problems and clinical outcomes) and "the use of the telephone" (survival item).
