MOSAiCH is a cross-sectional survey that focuses on the Swiss population’s values and attitudes towards a wide range of social issues. The thematic focus of the 2022 edition lies on Family and Changing Gender Roles, defined by the 2022 module of the International Social Survey Programme (ISSP) which is repeated for the fifth time (http://www.issp.org). This international part is supplemented by selected socio-demographic questions, as well as a module composed of questions specific to Switzerland. The questions of this Swiss part are selected through a public call, either expanding the ISSP module thematically or measuring other dimensions that are of special interest to Switzerland. Topics: - Family and Changing Gender Roles V (ISSP 2022), including international optional questions - Sociodemographics (education, work, income, household composition, religion, nationality, etc.) - Questions from 3 different proposals from the call on: 1) Gender Ideologies, Behaviours, and Identities; 2) Moving beyond the binary – Examining the advantages and challenges of a more complex sex and gender identity measure; 3) Knowledge and Attitudes towards Assisted Reproductive Technologies (ART) in Switzerland.
