Table 3.15 Initial mental disorder assessments for all episodes of care seen at a Department of Community Mental Health: numbers and rate ratios, by deployment and ICD-10 classification, 2010
Rate ratios provide a comparison of cases seen between personnel identified as having deployed to a theatre and those who have not been identified as having deployed to either theatre. A rate ratio less than 1 indicates lower rates in those deployed than those not deployed, and a rate ratio greater than 1 indicates higher rates in those deployed than those not deployed. If the 95% confidence interval does not encompass the value 1.0, then this difference is statistically significant.

Rates of 'other mental disorders' were lower in those that had deployed to the Iraq and/or Afghanistan theatres of operation than in those who had not deployed there. Rates of neurotic disorders, including adjustment disorders and PTSD, were higher among those deployed to the Iraq and/or Afghanistan theatres of operation compared with those not deployed there.

The data in this table are not National Statistics because they have not been designated as such by the Ministry of Defence.

1. Figures do not include personnel deployed to Afghanistan during the period January 2003 to October 2005 (see Mental Health Introduction for more information).
2. The previously reported 'Not Known' category has been removed as in 2010 all records were supplied with an deployment identifier.
