Data falsification in the European Social Survey? Stoop, I., Briceño-Rosas, R., Koch, A., & Vandenplas, C.Publications on this topic Working papers ESS9 FMS data upload portal - User manual.ESS9 Guidelines on fieldwork progress reporting.ESS9 Guidelines for enhancing response rates and minimising nonresponse bias.ESS9 Interviewer briefings: Interviewer manual.These activities include the definition of standards, the provision of support in implementing the standards, the analysis and documentation of survey procedures and numerous quality indicators, and, finally, the provision of feedback on any observed deficiencies. Taken together, the ESS aims to achieve a process of continuous improvement in data collection by implementing a coherent set of quality assurance activities. CST to analyse and document numerous quality aspects related to data collection (call schedule, refusal conversion, interviewer effects, sample composition, etc.).Each country to provide metadata (National Technical Summary) and paradata (contact forms data) to the ESS Data Archive.Each country to deposit the ESS main data set and all fieldwork documents (briefing materials, advance letters, contact forms, etc.) at the ESS Data Archive.For troubleshooting, survey organisations may be requested to provide more detailed information or investigate quality problems identified by the CST. The actual progress of fieldwork is compared with the benchmark data from the fieldwork projections to identify possible problems and a need for action. Each country to provide weekly case level information on fieldwork progress (in the form of a dataset) to the CST.To be provided by each country two weeks before fieldwork starts. Fieldwork projections: Forecasts of weekly production/response rates based on experience from previous rounds and current interviewer staffing. To be filled in by NCs, discussed by NC and CST, and agreed and signed-off by the CST four weeks before fieldwork starts. Fieldwork questionnaire: An instrument to discuss, help decide upon, and document major fieldwork decisions and parameters (timing of fieldwork, number of interviewers, etc.).Meeting of CST members with Field Directors to discuss data collection standards with the survey organisations appointed.To be taken into account in the planning of data collection for the upcoming round. Quality report: Country-specific feedback provided by the CST on a wide range of quality issues encountered in the previous round (see Data quality assessment page).At various points in the survey life cycle, countries are required to document and discuss the planning and progress of data collection. The whole process of preparation and implementation of data collection in each country is monitored by the CST. The slides are developed with a teaching approach which acknowledges the interviewers’ previous experience while identifying and remedying any gaps in their knowledge or skills. The training materials consist of an interviewer manual plus a series of pre-structured slides with movie clips. In order to foster compliance with these standards, the ESS Core Scientific Team provides guidelines, training materials, as well as individual feedback and support to countries. Quality control back-checks on completed interviews and ineligible cases.Contact forms to record and document data on fieldwork processes.Interviewer call schedule: 4 contacts attempts minimum, among which at least 1 in the evening and 1 at the weekend.Restricted interviewer workload (maximum 48 sample units gross).
