Several studies have developed web-based interventions for individuals with stimulant use disorders (amphetamines or cocaine). In a study conducted fully online in Australia, 160 individuals with self-reported amphetamine use problems were randomly assigned to a three-session computerized intervention based on MI with some components of CBT or a wait list control (Tait et al., 2014). Uptake of the computerized intervention was weak, with only 63% of those assigned to this condition accessing a module, and rates of 3-month follow-up were modest across conditions (57% of those in waitlist control and 48% of those assigned to computerized intervention). As standard outcomes (urinalyses or self-reported days of amphetamine use) were not reported, it was difficult to draw conclusions regarding the efficacy of the intervention in this sample.
