The CCHR has to be considered in context. Robert Whitaker's book, Anatomy of an Epidemic [1], makes the case that Scientologists were used by the drug companies to deflect criticism of the mass use of ineffective drugs:
THE CRITICS BELIEVE IN ALIENS
The story of a "psychopharmacology revolution" had first been
told in the 1950s and 1960s, and then, as we've seen in this chapter,
it was revived in the 1980s. However, the storytellers in the 1980s
were more vulnerable to criticism than the storytellers of the earlier
decades simply because there was now twenty years of research that
undermined their narative. None of the drugs had proven to help
people function well over the long term, and the chemical-
imbalance theory of mental disorders was in the process of flaming
out. As NIMH researchers had concluded in 1984, "elevations or
decrements in the functioning of serotonergic systems per se are not
likely to be associated with depression." ... There was a Grand
Canyon-sized gap between what the broken-brain storytellers
were intimating was true and what was actually known, and that
same gap would appear in their stories when Prozac and the other
second-generation drugs came to market. But fortunately for the
proponents of biological psychiatry, criticism of the medical model
and of psychiatric drugs became associated, in the public mind,
with Scientology.
...
... In 1969, Scientology and Thomas Szasz cofounded the Citizens
Commission on Human Rights, and this group began waging
campaigns against lobotomy, electroshock, and psychiatric drugs.
This proved to be very fortuitous for the APA [American Psychiatric
Association] and its storytelling partners as they raised the flag of
biological psychiatry. Indeed, it is easy to imagine the drug
companies deciding to secretly fund Scientology's protests, eager
as they were to shove money to any organization that would --
wittingly or unwittingly -- advance their cause. For not only did
Scientologist believe in extraterrestrials, they also had gained a
reputation for being a secretive, litigious, and even malevolent
cult. Scientology, Time wrote in 1991, is a "hugely profitable
global racket that survives by intimidating members and critics
in a Mafia-like manner." Thanks to Scientology, the powers that
be in psychiatry had the perfect storytelling foil, for they could
now publicly dismiss criticism of the medical model and
psychiatric drugs with a wave of the hand, deriding it as
nonsense that arose from people who were members of a
deeply unpopular cult, rather than criticism that arose from
their own research. As such, the presence of Scientology in the
storytelling mix served to taint all criticism of the medical model
and psychiatric drugs, no matter what its source.
Those were the storytelling forces that formed in the 1980s.
When Prozac arrived on the market, they were lined up perfectly
for the creation -- and maintenance -- of a tale about psychiatry's
great new leap.

I highly recommended this book for anyone who might ever have to defend themselves or someone their care about against a conventional psychiatrist.
