Nods Gambling Screen
Overview
The National Opinion Research Center DSM Screen for Gambling Problems (NODS) is a screening measure based on the DSM-IV. It is a telephone-screening tool that identifies gambling problems as defined by the DSM-IV. It includes 34 items that yield a total score ranging from 0 to 10. Scores of 1 or 2 suggests some risk for the individual. Scores of 3 or 4 implies possible harmful gambling. A score of 5 or higher indicates probable pathological gambling. These numbers correspond to the DSM-IV criteria of gambling problems.
A self-assessment version (NODS-SA) is also available. This tool helps individuals decide if they should change their gambling behaviour, or seek help for their gambling.
The Brief Biosocial Gambling Screen. The NODS-CLiP: A rapid screen for adult pathological and problem gambling. Journal of Gambling Studies, 25(4), 541-555.
RESULTS: The NODS-CLiP demonstrated perfect sensitivity for problem gambling, along with high specificity and a NPV, but a low PPV. Has there ever been a period when, if you lost money: gambling one day, you would return another day to get. NODS 14 Has your gambling ever caused serious or repeated: problems in your relationships with any of your family. Members or friends? A score of one or more is a positive screen. The NORC DSM-IV Screen for Gambling Problems (NODS) is a 17-item self-report screening instrument. The 17 NODS items yield a score ranging from 0 to 10, corresponding to the number of discrete DSM-IV criteria for pathological gambling. A NODS score of 5 or more qualifies as pathological gambling, whereas scores of 3 or 4 indicate problem gambling. The NORC Diagnostic Screen for Gambling Problems-Self-Administered (NODS-SA) was developed by staff from the National Opinion Research Center at the University of Chicago. The instrument is a modification of the NODS, a diagnostic instrument based on the American Psychiatric Association’s DSM-IV criteria for Pathological Gambling.
Key Points
Studies have shown that the NODS is a reliable tool used to measure behaviour in the gambling population. Because it is based on the DSM-IV, the symptoms it measures are proven to be related to problem and pathological gambling. The NODS covers all the symptoms dictated by the DSM-IV. However, it does not ask any questions related to the individual's own perception of his or her gambling. Many researchers criticize this tool because of this limitation.

This assessment tool was designed in the 1999 Gambling Impact and Behavior Study. A structured interview used to determine the prevalence of problem gambling in a population. The NODS consists of 17 questions intended to reflect the DSM-IV criteria It was developed and tested on non-clinical population, and is based upon DSM-IV criteria. Respondents to the NODS are classified as non-gamblers, low-risk, at risk, problem,
and pathological.

The SOGS was originally developed to screen for gambling problems in clinical populations and is a scientifically reliable and valid instrument of 20 items based on DSM III criteria for pathological gambling. It has been the most widely used assessment screen for problem gambling by researchers and counsellors, though it has not been specifically validated for that use.

The MAGS is a clinical tool that can be administered in a 5 to10 minute survey or interview. The MAGS presents an index of non-pathological (NPLG) and pathological (PLG) gambling based upon the criteria of the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). Outcomes also outline the prevalence of a variety of social and emotional problems associated with adolescent gambling.

The CAMH Gambling Screen is primarily based on the SOGS and contains 7 items in total. The first 5 were adapted directly from the SOGS. Another item was developed by Turner and Horbay; and the final item determines the frequency of problem gambling. This tool was essentially developed to screen for problem gamblers, to determine if problem gambling is an issue and if there is a need for treatment.
