An article in Rolling Stone magazine about an alleged gang rape on the campus of the University of Virginia has come under scrutiny for its reporting methods, even as the university and the local police investigate the events the article described.

The article began with one woman’s description of a violent rape in 2012 by seven members of a Virginia fraternity, complete with vivid and harrowing details. It criticized the university’s culture and fraternity system, and said that the supposed attackers had not yet faced any consequences. After the article’s publication last month, the case was handed to the Charlottesville, Va., police; the university vowed to update its policies; and the fraternity, Phi Kappa Psi, suspended its operations.

But some have also raised questions about the article. Its writer, Sabrina Rubin Erdely, a contributing editor at Rolling Stone, has faced criticism because she has acknowledged in interviews that she did not contact or interview the men accused of the rape. News organizations, seeking to be fair, usually seek comment from those suspected of criminal conduct.

In an interview Tuesday, Ms. Erdely said that she stood by her reporting.

“I am convinced that it could not have been done any other way, or any better,” she said. “I am also not interested in diverting the conversation away from the point of the piece itself.” The real scandal, she said, is that the university administration did not pursue the accusations further.
