2.3.1. Sociodemographic Variables and Contextual Variables

We gathered sociodemographic data on age (in ranges of 10 years) and sex. We used multiple choice questions for civil status and education. We included other sociodemographic contextual variables in the survey that we hypothesized could affect the home lockdown situation: number of people living in the home, people in a situation of dependence living in the home, and number of people under 18 or above 65 years old living in the home. We also collected self-reported data about their personal COVID-19 infection status (positive, negative, unknown, COVID-like symptoms), infected people close to them and people close to them that had died due to COVID-19.

Job insecurity, or concern about the possibility of job loss, was measured through a 4-item scale developed by de Witte [26]. An example item is: "Chances are I will soon lose my job." Participants give their responses on a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). Cronbach's alpha for this measure in our sample was 0.91. Worries about the future were measured through the 9-item scale developed by Höge et al. [27]. This measure was composed of three dimensions: labor, material and social worries. Labor worries reflected concerns about not maintaining their work conditions in the future and interference in their professional career (e.g., "I am worried about my future job conditions."). Material worries addressed worries about reduced income in the future and having fewer possibilities to satisfy material needs and wishes (e.g., "I am worried about a future decline in my income."). Social worries reflected worries about not maintaining and nurturing satisfactory family lives, partnerships, friendships, and other social contacts (e.g., "I am worried about not being able to have a happy family life or partnership in the future."). Responses ranged from 1 (strongly disagree) to 5 (strongly agree). Cronbach's alphas in our sample were 0.87 for labor worries, 0.87 for material worries and 0.77 for social worries.
