 First person symptom descriptions from memoirs, in-depth case studies, and analysis of large data sets, have illuminated the disorder in several ways: its classification and conceptualization (Hoffman &amp; Hansen 2017); the relation of affective states to the self (Ratcliffe &amp; Stephan 2014; Browne 2018); the disorder status of its mood-based phenomenology (Radden 2013); the relation of depression to autonomy, and to narrative theories of emotion in treatment contexts (Radoilska 2012; Biegler 2011); temporal experience (Fuchs 2001, 2013; Ratcliffe 2008), and many more.
