Item non-response to lifestyle assessment in an elderly cohort.
Greater attention is being paid to data quality in surveys of older age groups.
In this paper patterns of item non-response are examined in a health risk appraisal instrument administered to an elderly cohort participating in a randomized preventive intervention study.
The association between demographic and health status factors with the number of non-responses out of 174 items was examined at baseline and at the 12-month follow-up on 1791 subjects.
Overall, non-response decreased from baseline to 12 months.
The pattern was consistent across the seven major components of the questionnaire.
