Significant at the .05 level, two-sided test
PA-only = lifetime history of panic attack but not panic disorder or agoraphobia; PA-AG = lifetime history of panic attack with agoraphobia but not panic disorder; PD-only = lifetime history of panic disorder without agoraphobia; PD-AG = lifetime history of panic disorder with agoraphobia.
The original PDSS categories of severe and very severe were collapsed to define the severe category reported here.
Responses to the four SDS questions (impairments in function in work, home, social, and personal relationship functioning) were combined by assigning respondents their most severe score across the four. The original SDS categories of severe and very severe were collapsed to define the severe category reported here.
The number of respondents in each subgroup who reported 12-month prevalence does not equal the sample size in Table 1 multiplied by the estimate of 12-month persistence in that table due to the fact that persistence is estimated on weighted data and the sample sizes report the actual numbers of (unweighted) cases.
As the number of respondents with at least mild impairment is the additive inverse of the number with no impairment, the χ2 value in this row is identical to the value in the preceding row.
