Validity and reliability The psychometric properties of the scales used are described in the section ‘variables and measurements’ and in Table 1. The scales, originally written in English or German, have been translated into German and French with a forward and backward translation approach, assessing contextual fit with native speakers from the field (Schwendimann et al., 2014). Comprehensibility and understandability of items were assessed with care workers for the staff questionnaire.
