From the California Association of REALTORS, 12/10/2008:

New data shows that more than half of loans modified in the first quarter of 2008 fell delinquent within six months.

"After three months, nearly 36 percent of the borrowers had re-defaulted by being more than 30 days past due. After six months, the rate was nearly 53 percent, and after eight months, 58 percent," said U.S. Comptroller of the Currency John C. Dugan. A report scheduled to be published later this month will show continued increasing delinquencies and foreclosures in process for all first-lien mortgages held by the largest national banks and federally-regulated thrifts, Dugan said. However, new foreclosures decreased by 2.6 percent from the second quarter.

The mortgage metrics report covers nearly 35 million loans worth more than $6.1 trillion, or about 60 percent of all first-lien mortgages in the United States. The quarterly reports are unique in that they are not merely surveys, but instead consist of validated, loan level data using standardized definitions for prime, Alt-A, and subprime mortgages, and standardized definitions for loan modifications.
