NORC DSM Screen for Gambling Problems (NODS)

A structured interview used to determine the prevalence of problem gambling in a population. The NODS consists of 17 questions designed to reflect the DSM-IV criteria and was devised by the National Opinion Research Center (NORC) for the 1999 National Survey of Gambling Behavior. The NODS classifies respondents as non-gamblers, low-risk (gamblers with no adverse effects), at-risk (gamblers meeting one or two of the DSM criteria), problem (gamblers meeting three or four criteria), and pathological (gamblers meeting five or more criteria.)
