Variable 6RR 6SA 6SR 6STS PDA RMPI DSMS
6-month Readiness Ruler (6RR) .75** .27** .75** .44** −.27** −.33*
6-month Staging Algorithm (6SA) .07 .68** .50** −.45** −.47*
6-month SOCRATES Recognition (6SR) _ .36** .03 .38** .33**
6-month SOCRATES Taking Steps (6STS) _ .47** −.18* .29**

Notes: PDA = percentage of days abstained from marijuana, last 30 days, as measured by the Timeline Followback Interview; RMPI = Rutgers Marijuana Problem Index; DSMS = total count of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, marijuana abuse + dependence symptoms; a square root transformation was applied to the RMPI data; ns for the analyses ranged from 121 to 149.
