“…More specifically, feelings of “worthlessness” or “unworthiness” appear throughout the codification of different psychiatric disorders; it is one of the nine symptoms present in major depressive disorder (“feelings of worthlessness or excessive or inappropriate guilt…”), an aspect of the depressivity personality trait associated with Borderline Personality Disorder, and a functional consequence of developmental coordination disorder (American Psychiatric Association, 2022, p. 183). Additionally, this concept arises as a key feature of suffering in multiple qualitative studies of individuals with substance use and mental health disorders (e.g., Batchelder et al, 2013; Batchelder, Gonzalez et al, 2015; Batchelder, Peyser et al, 2015; Kidd et al, 2004). Despite a few exceptions in early clinical psychology (e.g., Freud in 1917/1993 and famously referenced by Rogers in his “conditions of worth” in 1959), personality, developmental, and social psychologists have, in more recent years, largely and problematically regarded self-worth as synonymous with the construct of self-esteem.…”
