The preparation of this annotated bibliography was guided by a desire to include all of the problem gambling research articles related to prevention that have been published in English. Some exceptions were made for articles published in other languages but for which an English abstract was available that provided sufficient details about the study. All studies were included, regardless of their methodological quality. In some cases, studies utilizing the same treated sample but providing additional results of the study were included. The annotations are brief and simply provide the reader with the full bibliographic reference, the basic approach that is evaluated in the study, and, when available, information about the results. No effort was made to critically appraise or review the study.
