Table 3.

Pretreatment Delay Discounting as a Predictor of Treatment Outcomes

Outcome	β
Percent days of marijuana abstinence during treatment	.06
Maximum consecutive days of marijuana abstinence during treatment	−.07
Percent marijuana-positive urine specimens during treatment	.03
Number of days in treatment	.10
Number of treatment sessions attended	.01
Percent days of marijuana abstinence during follow-up	.01

Note. Standardized coefficients (β) from linear regression models are presented, with delay discounting scores (natural logarithm of k) as the predictor. Posttreatment outcomes were assessed at 12 weeks, and the follow-up outcome was assessed at 1 year.
