A prominent Iranian author and psychiatrist who has been imprisoned and tortured frequently, said here yesterday that the Iranian government has no eased up on human rights violations despite the Carter administration's efforts.

Gholam-Hosseim Saedi, who has written numerous books, movies and plays many of which have been banned in Iran, said in an interview that "it is difficult to survive in Iran as a writer."

Saedi, who spent three years since his last release from prison seeking a visa to visit the United States, said the government only let him go because of international critcism which climaxed with demonstrations against Empress Farah in New York earlier this year.

For the most part, however, he said support by writers and publishers for the Writers Association, of Iran, which is fighting to ease censorship, "has not yet had the slightest impact on the government."

The author, who said the main purpose of his visit to the United States was to discuss publication of some of the his works in English for the first time, was particularly critical of government censorship. He said it has "propelled honest intellectuals, writers and artists toward self-censorship."

He said that during his last and longest arrest - for 11 months in 1974-75 - he was tortured frequently by agents of SAVAK, the Iranian secret police.

"They tried to get me to confess," he said. "I said I didn't know what to confess to an they said 'just confess.' I searched my mind to find something and finally said I aided Iraqi activities against Iran.

"That made them happy and I had the strange sensation of accusing myself of a lie."

He was reluctant to talk much about the torture but said the methods included electric shocks, pulling out his nails, banging his head against a wall and hanging him upside down by his feet.

Despite his sharp critcism of the government, he said he intends to return to Iran next month to continue his efforts to restore basic freedoms. His best-known work outside Iran is the film "The Blue Dome," which describes living conditions in Tehran slums. It won an award at the 1977 Paris Film Festival.
