Age differences in response accuracy for factual survey questions.

A R Herzog, L Dielman

    Journal of Gerontology
    |May 1, 1985
    PubMed
    Summary

    Older adults generally provide factual survey responses as validly as younger adults. The only exception was chronological age, which older individuals reported with slightly less accuracy.

    Area of Science:

    • Gerontology
    • Survey Methodology
    • Psychometrics

    Background:

    • Assessing the validity of self-reported data is crucial in survey research.
    • Age-related differences in reporting accuracy are not well understood.
    • Concurrent validity is a key measure of survey response accuracy.

    Purpose of the Study:

    • To examine the concurrent validity of survey responses across different age groups.
    • To determine if older respondents exhibit less accurate reporting compared to younger respondents.
    • To investigate age as a factor influencing factual information accuracy in surveys.

    Main Methods:

    • Analysis of data from four distinct surveys.
    • Comparison of survey responses with independent verification sources.
    • Examination of response validity stratified by respondent age.

    Main Results:

    • Little evidence suggests older respondents report factual information less validly than younger respondents.
    • Concurrent validity of responses for physical health, voting, transportation, charitable contributions, and library patronage showed no significant age-related decline.
    • Older respondents reported their own chronological age with slightly less validity.

    Conclusions:

    • Age is not a significant general predictor of reduced factual reporting accuracy in surveys.
    • Survey data from older adults can be considered largely as valid as that from younger adults.
    • Slightly reduced validity in self-reported chronological age among older individuals warrants further investigation.
