Psychoanalytic therapy is a type of mental health treatment that focuses on exploring the roots of psychological issues. There are various synonyms for this form of therapy, which include depth psychology, psychoanalysis, and psychodynamic therapy. Depth psychology emphasizes an analysis of unconscious motivations, and can encompass psychoanalytic or other therapeutic approaches that prioritize reflective exploration of one's inner experiences. Psychoanalysis, on the other hand, is a specific type of therapy founded by Sigmund Freud, and methodically interprets language, symbols, and unconscious material underlying a sufferer's symptoms. Psychodynamic therapy and psychoanalytic therapy are often used interchangeably, with both sharing a similar focus on exploring the unconscious.
