Structured Interviews
Consist of check-off responses to questions that are factual and easily fit an expected pattern
The interviewer should avoid soliciting additional
comments but, when they occur, record them verbatim.
- The main disadvantage of closed-ended questions is that they generally elicit only limited response patterns.
- The advantages are easy administration and data processing.

Unstructured Interviews
Provide open-ended response to questions
No predetermined response categories are provided.
Open-ended items may present a tabulation nightmare but provide the qualitative detail
and complexity of response that may be required, particularly if the subject of study
is little known.

Depth Interview
More intensive or detailed interviews that are particularly useful in life histories or case studies
The researcher has a general list of topics to be explored but exercises great discretion and flexibility in the manner, timing, and direction of questioning.

Advantages of Interviews
Disadvantages of Interviews
Personal contact between
researcher and subject
Interviewer can make use of cards, charts, & other AV aids
Time-consuming and costly
Interviewer effect/bias may distort results
Interviewer can pitch the language to respondent’s level
Interviewer may make errors in asking questions or recording information
Interviewer can use discretion as to the appropriate time to ask the more sensitive questions
Less convenient to the respondent, less anonymity than mail surveys

- Where possible, the field surveyors should match, as closely as possible, the subjects with respect to age, sex, race, social class, and dress. The interviewer’s language style should be adapted to the group studied.
- Attire should be comfortable, but the interviewer should be neither overdressed nor underdressed.
- Interviewers should have experienced a few practice interviews beforehand.
- Interviewers should assure respondents that their responses will be held in strictest confidence.
- Interviewers should attempt to build a rapport with the subjects.

Probing involves asking follow-up question(s) to focus, expand, clarify, or further explain the response given.
The interviewer should be familiar with the responses needed to each question to know when a probe is necessary.
The probe should not appear to be a cross-examination but should be a natural extension of the interview.

- The interviewer should use parentheses to distinguish personal observations from the actual interview.
- Editing entails reviewing the interview schedule after completion of the interview and cleaning it up and preparing it for analysis.
- Unanswered questions should be marked “NA” for “not applicable” or simply “X” to indicate “inappropriate.”
- Where personal observations are included, it may help to cross-reference relevant items.
- Interviewers should avoid summarizing/paraphrasing responses and try to use the respondent’s own words.

Advantages of Telephone Surveys
Disadvantages of Telephone Surveys
No field staff needed
Simpler monitoring/prevention
of interviewer bias
Difficulty in obtaining in-depth responses
Many numbers are unlisted
Quick and inexpensive
The poor and transient may not own phones
Generally yield a low nonresponse rate
Easy and inexpensive follow-up
If the survey is global, the cost could be prohibitive
Possible high refusal rates
