The LAS was one comprehensive score, summarizing physical, psychological, and social aspects.All questionnaires used in this study were self-completed questionnaires in Dutch version. Each participant received by e-mail a personal link to the questionnaire, which was sent from the eCRF. In current analyses, the Cronbach’s alpha was acceptable (α = ≥.70 < .80) for the EDS-3A, to good (α = ≥.80 < .90) for the EPDS, GMDS, sSTAI-6 and SOC at each timepoint.
