Measuring depression in the community: a comparison of telephone and personal interviews

Interview method effects in response to the Center for Epidemiologic Studies-Depression Scale (CES-D) are compared among a community sample (N = 546) of adults randomly assigned to either telephone or in-person interviews. The interviews were conducted in Los Angeles during 1980. No significant differences were observed between the two interview methods in nonresponse to symptom items, preference for specific response categories, reliability, mean level of depression, or proportion classified as depressed. Furthermore, no significant interactions were found between sociodemographic characteristics and the method of interview.
