Note. Addiction Severity Index composite scores in each domain range from 0 (no problems) to 1 (severe problems). In Beck Depression Inventory II, higher scores indicate more severe depression: minimal = 0–13; mild = 14–19; moderate = 20–28; severe = 29–63. The SF-12 Health Survey (SF-12), Physical Component Summary and Mental Component Summary scores have a range of 0 to 100 and were designed to have a mean score of 50 and a standard deviation of 10 in a representative sample of the US population. Scores greater than 50 represent above-average health status.
