Drawing on a study of UK national broadsheets, this article examines the emergence and spread of happiness as a social problem in the UK by drawing on the theoretical insights of social problem constructionism and related social movement theory in terms of the processual, rhetorical, and contextual factors involved in the construction, transmission, and institutionalisation of new social problems. In particular, issue ownership in the realm of process and flexible syntax, experiential commensurability, empirical credibility, and narrative fidelity in the realm of rhetoric are argued to have played an important role in the discursive spread of the happiness problem in this public arena. A socio-political context hospitable to de-politicised and highly personalised constructions of social issues is argued to have played a major contextual role in the construction of the ‘happiness problem’.
