INTERVIEWING OLDER ADULTS: MODE COMPARISON USING DATA FROM A FACE-TO-FACE SURVEY AND A TELEPHONE RESURVEY

A face-to-face survey conducted in 1984 with a sample of 1491residents of the Detroit metropolitan area (including an oversampleof older adults) and a reinterview of a random subset of theserespondents by telephone were used to compare the two modesof data collection across two age levels. Except for a tendencytoward a disproportionately large number of DK answers and adisproportionately large amount of interviewer assistance onthe telephone, respondents 60 years of age and older did notexhibit larger mode differences than did respondents under 60.For both age groups, response distributions were rather similar,suggesting little effect of mode. Likewise, response style differedlittle by mode, while a higher proportion of missing data (i.e.,"I don't know" answers) was given on the telephone. The responserate for the telephone reinterview was 90%, somewhat lower forolder than younger persons. The findings support the feasibilityof using the telephone for reinterviewing older adults.     

Effects of Questionnaire Length on Response Quality

A response tendency resulting from the length of a group-administeredquestionnaire instrument is described. Respondents answeringitems that are included in large sets toward the later partsof a long questionnaire are more likely to give identical answersto most or all of the items, compared with those respondingto items in smaller sets or in shorter questionnaires. Whilemeans and intercorrelations among items within the same setare affected by this "straight-line" response pattern, intercorrelationsbetween items from different sets are much less affected byit. These investigations are based on comparisons between along questionnaire, administered to 1,050 high school seniorsin nine high schools across the nation in 1978, and five shorterquestionnaires administered to large national samples of highschool seniors.     

LABOR FORCE MIGRATION AND ALLOCATIVE EFFICIENCY IN THE UNITED STATES: THE ROLES OF INFORMATION AND PSYCHIC COSTS

This paper examines the relative importance of information, psychic and other costs of relocation as mitigating factors (off-sets to spatial earnings differentials) within the migration decision. The methodology employed for this examination is based upon: (1) observation of relationships between the geographic allocation and personal characteristics of labor force migrants, and (2) inferences, drawn from these observations, on the relative importance of various relocation cost components. Empirical analyses of the migration decision based upon this indirect methodology provide important insights on both the determinants and allocative efficiency of interstate labor force migration in the United States.     

Interviewing Older Adults: A Comparison of Telephone and Face-to-Face Modalities

This article examines telephone interviewing of older adultsand compares it with face-to-face interviews. Specifically,the following issues are examined in several national surveys:(1) differences in age distributions between the samples ofadults reached in both modes; (2) explanations for potentialdifferences in age distributions; (3) differences between thetwo modes in demographic characteristics in the adults reached,in interview process and in response quality, and how thesemode differences vary by age of the respondents. Telephone surveystend to underrepresent older persons, and older persons whodo participate in a telephone survey are disproportion atelywell educated. Implications of the lower response rate amongolder persons are softened by the fact that reponse distributionsacross a range of questions show little difference by interviewmode between older persons and persons of other age groups.
