“…We developed the PET@home Toolkit using the Experience-Based Co-Design method ( Melchior et al, 2016 ). In preparation for this study, we conducted a qualitative systematic review ( Reniers et al, 2023a ) followed by semi-structured interviews using the Consensual Qualitative Research method and administered an online questionnaire to assess the content validity of the outcomes from the interview analyses ( Reniers et al, 2023b ). The outcomes of both these phases are reported in separate publications ( Reniers et al, 2023a ; Reniers et al, 2023b ), and provided the initial foundation for developing toolkit materials centred around seven themes identified in the literature review, namely relational aspects, reflection and meaning, emotional aspects, aspects of caregiving, physical health, social aspects, and bidirectional behaviour ( Reniers et al, 2023a ).…”
