The US’s leading professional psychologists’ organization helped justify CIA and Pentagon torture programs, a new 542-page report shows. The psychologists involved later profited from torture-related contracts.

The Central Intelligence Agency’s health professionals repeatedly criticized the agency’s post-Sept. 11 interrogation program, but their protests were rebuffed by prominent outside psychologists who lent credibility to the program, according to a new report.

The 542-page report, which examines the involvement of the nation’s psychologists and their largest professional organization, the American Psychological Association, with the harsh interrogation programs of the Bush era, raises repeated questions about the collaboration between psychologists and officials at both the C.I.A. and the Pentagon.

The report, completed this month, concludes that some of the association’s top officials, including its ethics director, sought to curry favor with Pentagon officials by seeking to keep the association’s ethics policies in line with the Defense Department’s interrogation policies, while several prominent outside psychologists took actions that aided the C.I.A.’s interrogation program and helped protect it from growing dissent inside the agency.

The association’s ethics office “prioritized the protection of psychologists — even those who might have engaged in unethical behavior — above the protection of the public,” the report said.

Two former presidents of the psychological association were on a C.I.A. advisory committee, the report found. One of them gave the agency an opinion that sleep deprivation did not constitute torture, and later held a small ownership stake in a consulting company founded by two men who oversaw the agency’s interrogation program, it said.

The association’s ethics director, Stephen Behnke, coordinated the group’s public policy statements on interrogations with a top military psychologist, the report said, and then received a Pentagon contract to help train interrogators while he was working at the association, without the knowledge of the association’s board. Mr. Behnke did not respond to a request for comment.

The report, which was obtained by The New York Times and has not previously been made public, is the result of a seven-month investigation by a team led by David Hoffman, a Chicago lawyer with the firm Sidley Austin at the request of the psychology association’s board.

After the Hoffman report was made public on Friday, the American Psychological Association issued an apology.

“The actions, policies and lack of independence from government influence described in the Hoffman report represented a failure to live up to our core values,” Nadine Kaslow, a former president of the organization, said in a statement. “We profoundly regret and apologize for the behavior and the consequences that ensued.”

The association said it was considering proposals to prohibit psychologists from participating in interrogations and to modify its ethics policies, among other changes.

The involvement of psychologists in the interrogation programs has been a source of contention within the profession for years. Another report, issued in April by several critics of the association, came to similar conclusions. But Mr. Hoffman’s report is by far the most detailed look yet into the crucial roles played by behavioral scientists, especially top officials at the American Psychological Association and some of the most prominent figures in the profession, in the interrogation programs. It also shows that the collaboration was much more extensive than was previously known.
