Following several months of psychoanalytic therapy, Karen has abruptly begun missing her scheduled sessions without apparent reason. This behavior is most likely indicative of which psychological phenomenon?

Explanation

Karen's sudden avoidance of therapy sessions exemplifies resistance, a defense mechanism where a patient unconsciously blocks or avoids confronting uncomfortable thoughts or feelings during psychoanalysis. Transference involves projecting feelings onto the therapist, insight refers to gaining understanding of one's issues, and catharsis is the emotional release experienced during therapy. Denial, while a defense mechanism, does not specifically describe avoiding therapy sessions.
