Abstract
Recent years have seen increased attention given to identifying and describing the levels of gambling participation that confer a risk of harm in order to generate public health advice regarding lower-risk gambling. However, most of the existing literature has failed to explicitly assess these limits in a prospective manner. The purpose of this study is to employ a methodology consistent with prior investigations to evaluate the level of gambling participation associated with an increased risk of future gambling-related harm. Using data from the Alberta Gambling Research Institute’s National Project Online Panel Survey, risk ratios and Receiver Operating Characteristic (ROC) analyses were used to determine the relative risk of gambling-related harm associated with participating in a greater number of gambling formats, gambling more days per month, and spending a greater proportion of income gambling. Prospective lower-risk limits were largely consistent with those identified in previous cross-sectional analyses (e.g., no more than two gambling formats, no more than once a week), with the exception that higher limits were found for the percent of household income spent gambling (3.4-6.4% vs. 1%). We advise that future research on lower-risk gambling limits consider the use of more granular assessment instruments and prospective methods to more closely evaluate the association between gambling participation and gambling harm.
