Caseness rates according to the Posttraumatic Diagnosis Scale (PDS > 20) and the General Health Questionnaire (GHQ > 3)
| PDS Cases (percentage of 2095 valid responses) | GHQ Cases (percentage of 2155 valid responses) | |||||||
|---|---|---|---|---|---|---|---|---|
| N | % | OR | CI | N | % | OR | CI | |

Note: OR = odds ratio for probable caseness compared to the no exposure group. CI = the 95% confidence interval for the OR estimate. *p < 0.05; ** p < 0.01. In the calculation of the OR, the logistic model controlled for gender, age and family structure and having a missing value on any of the items used in the construction of the exposure scale (parameter estimates for these covariates are not shown). N is restricted to those with valid responses on the PDS and the GHQ.
