We determined sociodemographic background through questions of age, gender, relationship status, number of underage children at home, education, and income. Gender options were male, female, and other. Only one participant reported other. For the analysis, we used a dummy-coded variable (0 = male, 1 = female/other). Relationship status referred to whether respondents were married or in another type of close relationship during the crisis (0 = no, 1 = yes). We requested information on education, with seven categories that we recategorized into three for study purposes: primary/secondary degree, degree from the university of applied science (usually bachelor level), and university degree (usually master's level or higher). We requested information about the participants' monthly gross incomes, with options ranging from 1 (less than 1000 €) to 8 (more than 7000 €).
