Language is not only mirroring our psychological world but also shaping it. Wellbeing literacy is defined as the capability of communicating about and for wellbeing through the use of language. As it is a relative new concept in positive psychology, appropriately conceptualising and measuring wellbeing literacy is basic for further research and practice. The present research will introduce a conceptual model of wellbeing literacy developed based on a systematic literature review of the definitions and concepts of literacy. The conceptual model of wellbeing literacy includes five domains: 1) vocabulary, knowledge and skills; 2) multimodal comprehending; 3) multimodal composing; 4) cross contexts; and 5) intention. Expanding upon this model, how it can be empirically tested and used to foster the development of a wellbeing literacy measure will be discussed.
