This Handbook gathers together empirical and theoretical chapters from leading scholars and clinicians to examine the broad issue of adult mental health. The contributors draw upon data from a variety of contexts to illustrate the multiple ways in which language as action can assist us in better understanding the discursive practices that surround adult mental health. Conversation and discourse analysis are useful, related approaches for the study of mental health conditions, particularly when underpinned by a social constructionist framework. In the field of mental health, the use of these two approaches is growing, with emergent implications for adults with mental health conditions, their practitioners, and/or their families. Divided into four parts; Reconceptualising Mental Health and Illness; Naming, Labelling and Diagnosing; The Discursive Practice of Psychiatry; and Therapy and Interventions; this Handbook provides a comprehensive overview of current debates regarding adult mental health.
