- Hazardous drinking in the prior 30 days (Self-reported number of days of hazardous drinking) [ Time Frame: 6 months ]Self-reported number of days of hazardous drinking (3+ drinks per day for women / 4+ drinks per day for men) in the prior 30 days.
- Drug use in the prior 30 days (Self-reported number of days of drug use) [ Time Frame: 6 months ]Self-reported number of days of drug use (illegal drug use or misuse of prescription drugs) in the 30 prior days.

If at least 4 of 9 are >0, the sum of item scores is used to indicate severity of depression: 1-4 Minimal; 5-9 Mild; 10-14 Moderate; 15-19 Moderately Severe; 20-27 Severe.
