Adjustment Disorder	0.6	(−1.5, 2.9)
MH/SUD Spending, Conditional on use	$ Change	95% CI
Bipolar Disorder
Total spending	−140	(−377, 94)
Out-of-pocket spending	−86	(−121, −52)
Major Depression
Total spending	−30	(−108, 49)
Out-of-pocket spending	−78	(−92, −63)
Adjustment Disorder
Total spending	−114	(−193, −41)
Out-of-pocket spending	−78	(−95, −63)

Notes: Individuals were identified for each diagnostic group based on ICD-9 diagnosis codes in 1999 claims data. The difference-in-difference results reflect changes pre- (2000) versus post (2002) for individuals in the FEHB Program group relative to individuals in the comparison group. CI refers to confidence interval. Entries appear in bold text if p≤0.007 (Bonferroni adjusted p. values for multiple comparisons equivalent to p.<.05).
