Broad Classification of Communication Methods in Survey Research
a) Interviewer-administered survey methods1. Personal Interviews.2. Telephone Interviews.
b) (Respondent) Self-administered survey methods.
1. Paper-based 2. Electronic
c) Mixed-mode surveys.

PERSONAL INTERVIEWS
Personal Interview – A form of direct communication in which an interviewer asks respondents questions face-to-face.
a) Door-to-Door Interviews – Interviews conducted at respondents’ doorsteps (in their homes)
b) Mall Intercept Interviews (Shopping Center Sampling) – Interviews conducted by intercepting respondents at a central location in a shopping mall
c) Pre-arranged Meetings – Interviewing respondents at other mutually agreed upon places

Advantages of Personal Interviews
1. Opportunity for feedback.
2. Opportunity to probe complex questions.
3. Willingness of respondents to spend longer time on interview.
4. Reduction in rate of item nonresponse (completeness of questionnaire).
5. Possibility of using visual aids & props.
6. High response rate / willingness of respondents to participate.

Disadvantages of Personal Interviews
1. Interviewer influence.
2. Respondent cannot be anonymous.
3. There may be a need for several callbacks (attempts to re-contact individuals who have been selected for a sample but who were not available during the earlier visit)
4. High cost.

TELEPHONE INTERVIEWS
• Interviewer-administered interviews that are conducted over the telephone.
• Telephone interviews are the most widely used method in commercial survey research
Telephone Interviewing Systemsa) Central Location Interviewing.b) Computer-Assisted Telephone Interview.c) Computerized Voice-Activated Telephone
Interviewing.

Telephone Interviewing Systems
1. Central Location Interviewing:
Conducting telephone interviews from a single central location from which all interviewers work
Usually through WATS (Wide Area Telecommunications Service) contracts that provide fixed long-distance rates, and allow unlimited calls within a specific geographic area
Allows Supervision and control.

Telephone Interviewing Systems2. Computer-Assisted Telephone Interviewing
(CATI):Telephone interviewing system in which the interviewer reads questions from a computer screen and enters the answers directly into the computer
• Usually incorporate telephone management systems that handle:
a) Phone number selection.b) Automatic dialing.c) Sample selection.d) Automatic callback scheduling.e) Reporting on number of completed interviews.

Telephone Interviewing Systems
3. Computerized Voice-Activated Telephone Interviews
• Computer assumes responsibility for all aspects of the interview administration
• It dials the respondent, asks the questions, and records the responses.
– Used mainly for short, simple questionnaires.
Dr. Alhassan G. Abdul-MuhminKing Fahd University of Petroleum and Minerals
11
Advantages of Telephone Interviews
1. Relatively high speed of data collection.
2. Inexpensive compared to personal interviews.
3. Better respondent anonymity than personal interviews.
4. Relatively higher respondent cooperation lower nonresponse compared to personal interviews.
Dr. Alhassan G. Abdul-MuhminKing Fahd University of Petroleum and Minerals
12
Disadvantages of Telephone Interviews
1. Problems in getting representative samples; unlisted phone numbers; random digit dialing as solution.
2. Problem of answering machines & faxes.
3. Need for callbacks.
4. Respondent can easily hang up.
5. Inability to use visual aids.
6. Need for shorter forms of questioning.

[RESPONDENT] SELF-ADMINISTERED SURVEYS
• Surveys in which respondents take the responsibility for reading and answering the questions.
• Present a special challenge in questionnaire design because self-administered surveys rely on the efficiency of the written word rather than the skill of the interviewer.
• Self-administered questionnaires can be classified into paper-based (printed) or electronic (non-printed)

Paper (Printed) Self-Administered Questionnaires
Distribution Methods
1. Mail (or Postal) Surveys – using regular mail system (now usually called “Snail Mail Surveys”).
2. Drop-off / Pick-up method.
3. Fax surveys
4. Inserts – e.g. in product packages, magazines, etc.
5. Direct distribution to customers – e.g. in restaurants, airplanes, banks.
6. Warranty / Owner registration cards.

2. Lower cost.
3. Respondent convenience– Respondent can take time to think about
response.– Respondent has chance to check records for
information.
4. Respondent anonymity.

ISSUES IN CHOICE OF COMMUNICATION METHOD
• Is the assistance of an interviewer necessary?
• Are respondents interested in the issues being investigated?
• Will cooperation be easily attained?
• How quickly is the information needed?
• Will the study require a long and complex questionnaire?
• How large is the budget?
