†
The rates of individual reported diagnoses are a percentage of the total sample. Participants could endorse more than one diagnosis. The abstinence rates for specific diagnoses were not statistically compared with the no psychiatric history group due to the small sample sizes. It should be noted that during the initial telephone screen all participants reported that they did not have a history of psychosis or bipolar disorder, but at the initial visit 6 participants reported a history of bipolar disorder diagnosis or treatment and 2 reported a history of schizophrenia.
