3. Interviews as Interactive
Communication
• Interactive Survey Approaches
– Those that allow spontaneous two-way interaction
between the interviewer and the respondent.
– Can be either personal or electronic.
• Noninteractive Media
– Those that do not facilitate two-way communication
and are largely a vehicle by which respondents give
answers to static questions.
• Tradition forms with less flexibility
• Self-administered mail and Internet surveys
10–3
4. Personal Interviews
• A personal interview is a form of direct
communication in which an interviewer asks
respondents questions face-to-face.
– Versatile and flexible
– Truly interactive

respondents’ doorsteps in an effort to
increase the participation rate in the survey.

– Attempts to recontact individuals selected for a
sample who were not available initially.

moderate

excellent

versatile

may be shown or demonstrated;
extended probing possible

9. Mall Intercept Personal Interview
• Personal interviews conducted in a shopping
mall.

central point within the shopping center or at
the main entrance.
10–9
10. Mall Intercept Interview

10–10
11. Personal Interviews
• Global Considerations
– Variations in willingness to participate
• Sensitivity to interview subject matter
• Beliefs about appropriate business conduct
10–11
12. Telephone Interviews
• Telephone Interviews
– Personal interviews conducted by telephone.
– The mainstay of commercial survey research.
– “No-call” legislation has limited this capacity.
• Mobile Phone Interviews
– In U.S., no telemarketing can be directed toward
mobile phone numbers.
– Recipient of call is even more likely to be distracted.
– Area codes not necessarily tied to geography.
– Phones have varying abilities.
10–12
13. Phone Interview Characteristics
• Speed
• Cost
• Absence of face-to-face contact
• Cooperation
• Incentives to respond
• Representative samples
• Callbacks
• Limited duration
• Lack of visual medium
10–13
14. Types of Telephone Interviews
• Central Location Interviewing
– Conducting interviews from a central location allowing firms to hire a
staff of professional interviewers and to supervise and control the
quality of interviewing more effectively.
• Computer-Assisted Telephone Interviewing (CATI)
– Allows answers to telephone interviews to be entered directly into a
computer for processing.
• Computerized Voice-Activated Telephone Interview
– Combining computerized telephone dialing and voice-activated
computer messages to allow researchers to conduct telephone
interviews without human interviewers.
10–14
15. Telephone Interview Recap
• Speed of data collection: very fast
• Geographical flexibility: high
• Respondent cooperation: good
• Versatility of questioning:
moderate
• Questionnaire length: moderate
• Item nonresponse: medium
• Possibility of respondent
misunderstanding: average
• Degree of interviewer influence
of answer: moderate
• Supervision of interviewers: high,
especially with central location
interviewing
• Anonymity of respondent:
moderate
• Ease of call back or follow-up:
easy
• Cost: low to moderate
• Special features: fieldwork and

– Persons who will complete questionnaires versus
those persons who will not.
– Person filling out survey is not the intended
subject.
