Mean Change in Treatment Outcomes from Baseline to 12 Month Follow-up by Number of Inconsistencies in the Reporting of Substance Use Recency.

	N	Substance Use Frequency Scale^a	Substance Problem Scale^a	Illegal Activities Index	Time in ControlledEnvironment^b	Emotional Problems Index^a
Number of Inconsistencies
0	324	−1.09	−0.55	0.28	20.03	−0.05
1	312	−1.35	−0.70	0.30	19.97	−0.05
2	266	−1.75	−0.76	0.29	24.03	−0.05
3	204	−1.95	−0.87	0.30	24.63	−0.08
4+	357	−2.04	−1.02	0.29	27.54	−0.11

The estimated slope in the linear regression of the number of inconsistencies the given outcome measure was statistically significant from zero (e.g., p-value < 0.05).

Mean time in controlled environment is for 12-month follow-up visit only. It is not the mean change from baseline.
