Telephone versus in-person surveys of community health status.
Reports of physical morbidity are compared among a community sample of Los Angeles County adults (N = 546) randomly assigned to either in-person or telephone interviews. No statistically significant differences were found between the two interview methods for overall assessment of health status, illnesses reported for the previous four months, or reports of hospitalization. A significantly greater proportion of in-person respondents, however, reported the presence of restricted-activity days during the previous two weeks. This difference could not be directly attributed to sociodemographic characteristics or reported physical health status of the two samples.
