The Department of Defense has released its latest study of the mental health of soldiers and marines in Iraq. The fourth Mental Health Advisory Team report (MHAT-IV; "emm hat four"), among other findings, confirms that multiple and lengthened deployments for soldiers and marines are causing increased mental health problems for troops.

The report is long -- 89 pages with 20 appendices -- and contains a wealth of information about what troops are enduring in Iraq. The report's findings include:

• Soldier and marine morale is worsening (this is a problem because low morale leads to poor "unit cohesion" which is a risk factor for developing Post-Traumatic Stress or other mental health problems);
• about 20 percent of soldiers met screening criteria for a mental health problem (anxiety, depression or acute stress) -- an increase from previous years;
• the "linear relationship" between combat exposure and subsequent mental health problems was further confirmed (nearly one third of troops who had seen "high combat" met criteria for a mental health problem);
• troops with a mental health problem are not likely to seek help because a perceived stigma against such problems -- of the 20 percent of solders who met screening criteria for a mental health problem, only 42 percent sought help.

The report was written in November 2006, and was released to the public May 4, 2007. (While some find that 6-month delay suspicious, it's worth noting that the MHAT-IV was released much more quickly than the MHAT-II, which was delayed 8 months, and the MHAT-III, which was delayed a full year.)
