Frequency of survey research studies containing one or more measures of expert-defined need, consumer-defined need, or both expert and consumer-defined need, by publication year (n = 1594). Expert-defined need: reporting one or more of: prevalence of substance use, prevalence of substance use disorders (using some expert diagnostic criteria), and/or substance use service utilization rates. Note that ‘user-only’ studies (i.e., studies where eligibility criteria included substance use) were only coded as reporting a substance use prevalence estimate when survey data were combined with administrative data to estimate population prevalence of use. Consumer-defined need: reporting one or more of: perceived need for substance use services, self-assessed barriers to accessing substance use services, and/or informal help-seeking from family or friends. 36 studies published between January 1 and May 28 2015 were excluded from this figure due to incomplete data for 2015
