Very important findings that challenge established 'Models of Madness'. Very important also for any approach - like Open Dialogue and Voice dialogues/ Hearing Voices groups - that are explicit about not being specifically grounded in psychodynamic developmental or neuro-cognitive models.
Life histories IN social context investigations much needed, but not discussed within the scope of this review. Highly recommended reading.
