Major depressive disorder (MDD), also known as clinical depression, is a mental disorder characterized by at least two weeks of pervasive low mood, low self-esteem, and loss of interest or pleasure in normally enjoyable activities. Introduced by a group of US clinicians in the mid-1970s, the term was adopted by the American Psychiatric Association for this symptom cluster under mood disorders in the 1980 version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), and has become widely used since. The disorder causes the second-most years lived with disability, after lower back pain.

The diagnosis of major depressive disorder is based on the person's reported experiences, behavior reported by family or friends, and a mental status examination. There is no laboratory test for the disorder, but testing may be done to rule out physical conditions that can cause similar symptoms. The most common time of onset is in a person's 20s, with females affected about three times as often as males. The course of the disorder varies widely, from one episode lasting months to a lifelong disorder with recurrent episodes. (Full article...)

Albert Ellis (September 27, 1913 – July 24, 2007) was an American psychologist and psychotherapist who founded rational emotive behavior therapy (REBT). He held MA and PhD degrees in clinical psychology from Columbia University, and was certified by the American Board of Professional Psychology (ABPP). He also founded, and was the President of, the New York City-based Albert Ellis Institute. He is generally considered to be one of the originators of the cognitive revolutionary paradigm shift in psychotherapy and an early proponent and developer of cognitive-behavioral therapies.

Based on a 1982 professional survey of American and Canadian psychologists, he was considered the second most influential psychotherapist in history (Carl Rogers ranked first in the survey; Sigmund Freud was ranked third). Psychology Today noted that, "No individual—not even Freud himself—has had a greater impact on modern psychotherapy." (Full article...)
