The Parchemins study: a study of the impact of the Papyrus regularisation programme on the health and living conditions of undocumented migrants in Geneva aimed to follow undocumented migrants over a period of 4 years in order to have time to evaluate the effects of obtaining a residence permit on their living conditions and health status (Jackson, Courvoisier, et al., 2019). Participants were recruited through the associations involved in 'Operation Papyrus' and the CAMSCO. In the first wave of data collection, which took place between 2017 and 2018, 468 people were recruited. They were over 18 years of age, from countries outside the European Union (EU) or the European Free Trade Association (EFTA). They had been living in Geneva for at least 3 years and planned to stay for at least another 3 years. Migrants who had applied for asylum were not included in the study.
The quantitative component involved 4 successive waves of data collection, planned at approximately one-year intervals between 2017 and 2022. A standardised questionnaire was administered face-to-face with the help of a digital tablet. The questionnaire is available in different languages (French, Spanish, Portuguese and English) and the data collectors - interns and students
of medicine, social sciences and economics - are selected to cover the main languages present in the study population. In addition to the socio-demographic characteristics of the participants, the questionnaire assesses their living conditions (housing, quality of
life), employment conditions, health status and access to health care.
