The purpose of this study was to examine whether recovery rates differed between people who gambled online and those who gambled offline at one and two years after beginning treatment. Data from 237 adults who began outpatient treatment for gambling disorder were used in this study. Participants completed a standardized clinical evaluation at the start of care and at 12 and 24 months after. Among participants who did not drop out, the majority achieved middle-term (i.e., at 1 year, 74%) and long-term (i.e., at 2 years, 79%) recovery. There were no differences in recovery rates between those who gambled online and those who gambled offline at these two time points. Participants with higher perceived self-efficacy (i.e., believed that they could control their gambling) and those who did not have a history of mood disorders were more likely to achieve middle-term recovery. Participants with lower level of sensation seeking were more likely to achieve long-term recovery.
