They were responsible to provide a GGS specific training of interviewers in each voivodship. 2.3 Length: 1 day + contacts during the pilot survey. The pilot survey report was prepared and sent to the coordinators. 2.4 Control of performance: Checking the full- filled questionnaires, FAQ was active during the fieldwork. 2.5 Interviewer survey: Yes.

3. Contact protocols 3.1 Advance letter:Before a visit of an interviewer each household selected in the sample received a letter with a description of the study (content of the survey, being a part of the GGP, the agencies involved in the survey, the future use of the data, etc). The household was also invited to visit the project website (http://www.sgh.waw.pl/ggs-pl/) to find more information about the survey and the whole project. 3.2 Cold contacts: Face-to-face. 3.3 Scheduling / scattering: In the case of short-term absence of the selected respondent, the interview could have been postponed to the next date.

The ISD team members were under disposal of the regional survey coordinators. They were contacted either by phone or via e-mail. FAQ was active during the fieldwork.

WAVE 2 DATA COLLECTION

1. Interviewers 1.1 Total number of interviewers: NA 1.2 Number of interviewers in the field: NA 1.3 Network organization: Fieldwork coordinators designated by the Bureau of Research and Statistical Analyses which was responsible for the fieldwork. 1.4 Working arrangement of interviewers: Professional interviewers employed by the Central Statistical Office (CSO) and experienced in performing CSO surveys. 1.5 Payment of interviewers: Paid per interview.

2. Interviewer training:
   2.1 General interviewing: Coordinators of the field study and selected interviewers were already trained in general interviewing techniques: interviewing techniques, appointments taking and general knowledge on surveys carried out by CSO. 2.2 Survey specific: The fieldwork coordinators of CSO were already familiar with the GGS - in July 2014 they received detailed information on new aspects of Wave 2. They were responsible to provide GGS specific training of interviewers in each voivodship. 2.3 Length: NA 2.4 Control of performance: Checking the filled out of questionnaires, FAQ was active during the fieldwork. 2.5 Interviewer survey: Yes. It included mainly questions concerning the conditions under which the interview was conducted (e.g. a way of filling in the questionnaire, a presence of other household members, their possible influence on answers received, a general attitude of a respondent).

3. Contact protocols 3.1 Advance letter: Before a visit of an interviewer each household selected in the sample received a letter with a description of the study (content of the survey, being a part of the GGP, the agencies involved in the survey, the future use of the data, etc). The household was also invited to visit the project website (http://www.sgh.waw.pl/ggs-pl/) to find more information about the survey and the whole project. 3.2 Cold contacts: Face-to-face. 3.3 Scheduling / scattering: In Wave 2 new possible reasons for non-interviewing came to place: the address did not exist anymore, the respondent left the household (here a new address was seeking by an interviewer), the respondent died, the household moved to another place. Therefore, beside the similar rules to contact the respondent as in Wave 1, additional rules were established to reduce attrition. 3.4 Contact history: No, the contact history was recorded only in case of the interview was run (or an attempt to run it). 3.5 & 3.6 Min and Max number of contacts: The rule to contact a respondent of Wave1 was extended: if a respondent/a household was not located at the Wave 1 address, the new address/a new location had to be established whenever possible. If a respondent moved to another place of residence in Poland, an attempt to contact him was recommended either by the same regional team of interviewers or by the new regional team.

4. Questionnaire localization 4.1 Validation: Back translation 4.2 Pre-test: Interviews carried out in July 2014: the questionnaire of Wave 2 (respondents in the panel) was tested internally in selected regional statistical offices. The fieldwork coordinators of CSO were responsible for collecting all comments and doubts concerning the questionnaire. After discussing all comments both the survey questionnaire and the survey instruction were adjusted accordingly. After the interview, interviewers were completing a short survey on the quality of the interview. The data is available from ISD upon request. The ISD team members were under disposal of the regional survey coordinators. They were contacted either by phone or via e-mail. FAQ was active during the fieldwork.
