Primary Outcome Measures

Name	Time	Method
South Oaks Gambling Screen (SOGS)	6-Months	The 20-item South Oaks Gambling Screen (SOGS) measures gambling involvement and problem severity based on DSM-III-R pathological gambling criteria.
Gambling Quantity and Perceived Norms Scale (GQPN)	6 Months	The gambling quantity and perceived norms scale (GQPN) includes a six-item expenditure subscale assessing amount of money won/lost through gambling on a 10-point scale from $0 to more than $2000 over time-periods from the past month to past year. Additional items assess gambling frequency (on a 10-point scale from never to every day in the past year), disposable income (on an 11-point scale from less than $50 to more than $500 per month) and perceptions of gambling frequency and expenditure for the typical college student (perceived norms). Gambling expenditure was calculated as the expenditure subscale mean residualized on disposable income.
Gambling Frequency (SOGS)	6 Months	The SOGS was modified to assess internet gambling frequency and expand gambling frequency response options from a three- to a five-point scale with anchors of no times, one to 10 times, more than 10 times, less than weekly, weekly or more than weekly but less than daily, and daily. This modified frequency scale has been shown to correlate highly with other measures of gambling frequency.
Gambling Problems Index (GPI)	6 Months	Gambling problems (or negative consequences) were assessed using the 20-item Gambling Problems Index (GPI). Participants indicated how often, from never to more than 10 times in the past 6 months, they experienced consequences while, or as a result of, gambling.
National Opinion Research Center DSM-IV Screen for Pathological Gambling (NODS)	6 Months	DSM-IV \[1\] criteria for pathological gambling were assessed using the 17-item National Opinion Research Center DSM-IV Screen (NODS). Some criteria have multiple items, but possible scores range from 0-10 DSM-IV criteria endorsed in the past 6 months.

Secondary Outcome Measures

Name	Time	Method
Illusions of Control	6 Months	Illusions of control were assessed via a six-item subscale from the Beliefs About Control Scale (BACS), on a five-point scale ranging from strongly disagree to strongly agree.
