Stage 2. Selection of Sample Village.
In each selected regency/city, village names were listed and then two were selected by systematic random sampling.
Stage 3. Selection of Households.
In each selected village, five Rukun Tetangga (RT, neighborhoods) were established by random numbers. In each selected RT, households were listed and two of them were selected by using random numbers.
Stage 4. Respondent Selection.
In every selected household, voting age members were listed (male or female only). One person was then selected to be a survey respondent based on the Kish Grid system.
Stage 5. Substitution.
In case the selected respondent could not be interviewed (e.g., unavailable after two visits to the household during interview time set for a particular village, interview refusal, etc.), the respondent was substituted with a voting-age person from the household to the left side of the originally selected household. Selection of that respondent followed Stage 4. In case the newly selected respondent could not be interviewed, the interviewer moved to the right side of the originally selected household.
The same procedure for selecting a respondent from that household was applied.
5. Research Methodology a. Preparation
(1) Questionnaire
The definitive language version of the questionnaire is Bahasa Indonesia, which is a translated version from the original questionnaire in English. Then the language translation underwent cognitive pretests to make sure that the messages were conveyed accurately.
(2) Pre-Testing and Finalizing the Questionnaire
LSI pre-tested the questionnaire on 17 voting-age adults from different socio-economic classes in order to:
- Determine the time length of the interview,
- Improve the wording of the questions, if necessary,
- Eliminate unnecessary questions or add new items, as the case may be, - Test question sequence and identify bases,
- Correct and improve translation,
- Change open-ended questions into multiple-choice questions, - Find out which items are conceptually vague,
- Check accuracy and adequacy of the questionnaire instructions,
- Determine whether the focus of the question is clear, and - Identify interviewer’s recording difficulties.
(3) Training
(c) LSI had two levels of trainings. LSI conducted the first level of training in Jakarta by inviting all areas coordinators of LSI to special sessions. The aim of this training was to give the coordinators a general picture of the survey, as well as read and review the questionnaire. The second level of training took place in various provinces of Indonesia. The area coordinators who received knowledge disseminated information to surveyors in their respective areas. Particular attention was given to areas with large primary sampling units such as West Java, Central Java, and East Java and where researchers from LSI’s head office were most involved in the training.
(b) Training time - The minimum training time for group supervisors and interviewers was two days prior to field implementation. The third day was the start-off, where the field supervisor observed the field interviewers during their first round of interviews.
(c) Training Activities - These mainly consisted of one or two days of office training to learn the basics of the project and mock interviews among participants. The latter activity meant that field interviewers interviewed field anchors as if they were respondents in order to get accustomed to the flow of interviewing and the questionnaire format. Interviewers practiced with a supervisor until they could sufficiently conduct interviews on their own.
(f) Evaluation of interviewer’s work - A field supervisor observed and evaluated all of the first interviews of each field interviewer. Only after meeting certain evaluation criteria was an interviewer left to interview on her own. The field supervisor always stayed within the vicinity of the sample spot to conduct checks, however.
b. Fieldwork
(1) Workers on Hand
For this project, LSI deployed a total of 174 field staff:
Overall Field Manager = 1
Western Indonesia Field Anchors = 12 Field Interviewers = 135
Central Indonesia Field Anchors = 10 Field Interviewers = 35
Eastern Indonesia Field Anchors = 2 Field Interviewers = 4
(2) Supervision
Supervisors reported to the field manager and monitored the study full-time. They observed interviewers, where at least 10% of the total interviews were observed by supervisors, conducted follow-ups, and did surprise checks on the field interviewers.
They also ensured that field logistics were received promptly and administered properly.
(3) Spot-checking
Part of quality control was to make sure at least 30% of each interviewer’s output was spot-checked and back-checked. Once an incomplete or inconsistent answer was spotted in the questionnaire, the field interviewer went back to the respondent’s house to re-ask the question for verification.
c. Field Editing
(a) After each interview, the interviewer was asked to go over his or her own work and check for consistency.
(b) All accomplished interview schedules were submitted to the assigned group supervisor who, in turn, edited every interview.
(c) Data Processing
(1) Office editors conducted final consistency checks on all interviews prior to coding.
(2) A data entry computer program verified and checked the consistency of the encoded data before data tables were generated.
