a
Actual n differs by variable due to missing data. On average, 1.5% of responses were missing (range = 0 to 4.9% missing)
b
Percent of sample indicating they had not used any substances in the past month, were living in the community, and had no past month DSM IV criteria for SUDs. This effect size is an Odds Ratio (95% CI: .36 to .92). All other effect sizes are reported as Cohen’s d.
