Inconsistent use of terms such as positive mental health, flourishing, and mental wellbeing across disciplines limits reliable measurement, intervention design, and policy development. In this study, researchers aimed to gather a consensus on a preliminary taxonomy of positive mental health dimensions using the Delphi method.

Six dimensions reached over 90% agreement across experts from 11 relevant disciplines: meaning and purpose, life satisfaction, self-acceptance, connection, autonomy, and happiness.

This taxonomy supports more consistent conceptualisation and greater cross-disciplinary alignment, helping to strengthen the development of interventions and policy.
