Table 3.15 Initial mental disorder assessments for all new cases seen at a Department of Community
                        Mental Health: numbers and rate ratios, by deployment and ICD-10 classification, 2009
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 mood disorders and '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.

Rate ratios of initial mental disorder assessments for all new cases seen at a
Department of Community Mental Health: by ICD-10 classification, 2009
This graph presents the rate ratios comparing personnel identified as having deployed to the Iraq and/or Afghanistan theatres of operation and those who have not been identified as having deployed to either theatre. The rate ratio is represented as a square block on the graph with the upper and lower 95% confidence limits above and below. The bold red line on the graph is at 1. A confidence interval which lies entirely below this line indicates statistically significantly lower rates in those deployed than those not deployed, whereas a confidence interval that lies entirely above the red line indicates statistically significantly higher rates in those deployed than those not deployed.
