ABSTRACT This article examines the rhetorical productivity of ambiguity in the context of a loosely-defined mood disorder formally known as dysthymia, referred to colloquially as mild depression. First, the article offers a rhetorical history of the unusual institutional conditions under which this definitionally ambiguous diagnostic entity was constructed prior to its debut in the DSM-III. Second, the article explores how dysthymia’s definitional ambiguity functions as a rhetorical resource in the context of contemporary online health interactions.
