The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) is a synthesis model of interpersonal and cognitive and behavioral therapies developed (and patented) by James P. McCullough Jr of Virginia Commonwealth University specifically for the treatment of all varieties of DSM-IV Chronic Depression. CBASP is often mistakenly labeled a variant of Cognitive Therapy (CT) or Cognitive Behavioral Therapy (CBT) but it is not. Dr. McCullough writes that Chronic Depression (i.e., depressive disorder in adults that lasts continuously for two or more years; one year continuously in adolescents), particularly the type beginning during adolescence (early-onset), is essentially a refractory "Mood Disorder" arising from traumatic experiences or interpersonal psychological insults delivered by the patient's Significant Others (nuclear or extended family).
