Thomas Szasz, a psychiatrist whose 1961 book “The Myth of Mental Illness” questioned the legitimacy of his field and provided the intellectual grounding for generations of critics, patient advocates and antipsychiatry activists, making enemies of many fellow doctors, died Saturday at his home in Manlius, N.Y. He was 92.

He died after a fall, his daughter Dr. Margot Szasz Peters said.

Dr. Szasz (pronounced sahz) published his critique at a particularly vulnerable moment for psychiatry. With Freudian theorizing just beginning to fall out of favor, the field was trying to become more medically oriented and empirically based. Fresh from Freudian training himself, Dr. Szasz saw psychiatry’s medical foundation as shaky at best, and his book hammered away, placing the discipline “in the company of alchemy and astrology.”

The book became a sensation in mental health circles, as well as a bible for those who felt misused by the mental health system.

Dr. Szasz argued against coercive treatments, like involuntary confinement, and the use of psychiatric diagnoses in the courts, calling both practices unscientific and unethical. He was soon placed in the company of other prominent critics of psychiatry, including the Canadian sociologist Erving Goffman and the French philosopher Michel Foucault.

Edward Shorter, the author of “A History of Psychiatry: From the Era of the Asylum to the Age of Prozac” (1997), called Dr. Szasz “the biggest of the antipsychiatry intellectuals.”

“Together,” he added, “they tried their hardest to keep people away from psychiatric treatment on the grounds that if patients did not have actual brain disease, their only real difficulties were ‘problems in living.’ ”

This attack had some merit in the 1950s, Dr. Shorter said, but not later on, when the field began developing more scientific approaches.

To those skeptical of modern psychiatry, however, Dr. Szasz was a foundational figure.
