Table 2.

Percentages of lifetime first onsets (past plus current) (n = 90) and percentages of current first onsets (n = 60) of war-related PTSD in the 260-member SCID-diagnosed subsample of veterans with and without adjustments for the requirements of impairment and/or independent documentation of traumatic exposure. Sample n values are in parentheses and percentages are based on data weighted to reflect the complex sampling design (22). (Omitted from the analysis are four veterans with prewar onsets, two missing onset information, and one missing a sampling weight.)

Adjustments	Lifetime (%)	Current (%)
Unadjusted	22.5	12.2
Adjusted for impairment of functioning	21.0	10.4
Adjusted for documentation of exposure	20.3	11.1
Adjusted for both impairment and documentation	18.7	9.1
