Temporal relationships between Gulf War deployment and subsequent psychological disorders in Royal Australian Navy Gulf War veterans

Key Hospital Anxiety and Depression Scale (HADS) items associated with DSM-IV depressive and anxiety disorder 12-months post traumatic brain injury

BACKGROUND

Anxiety and depression are common problems following traumatic brain injury (TBI), warranting routine screening. Self-report rating scales including the Hospital Anxiety and Depression Scale (HADS) are associated with depression and anxiety diagnoses in individuals with TBI. The relationship between individual HADS symptoms and structured clinical interview methods (SCID) requires further investigation, particularly in regard to identifying a small number of key items that can potentially be recognised by clinicians and carers of individuals with TBI.

METHODS

138 individuals sustaining a complicated-mild to severe TBI completed the HADS, and the Structured Clinical Interview for DSM-IV, Research Version (SCID) at 12-months post-injury. The associations between individual HADS items, separately and in combination, as well as overall depression and anxiety subscale scores, and SCID-diagnosed depressive and anxiety disorders were analysed.

RESULTS

CART (Classification and Regression Tree) analysis found HADS depression item 2 "I still enjoy the things I used to enjoy" and a combination of two anxiety items, 3 "I get a sort of frightened feeling as if something awful is about to happen" and 5 "worrying thoughts go through my mind", performed similarly to total depression and anxiety subscales in terms of their association with depressive and anxiety disorders respectively, at 12-months post-injury.

LIMITATIONS

Patients were predominantly injured in motor vehicle accidents and received comprehensive care within a no-fault accident compensation system and so may not be representative of the wider TBI population.

CONCLUSIONS

Although validation is required, a small number of self-report items are highly associated with 12-month post-injury diagnoses.

Predictors of changes in daily alcohol consumption in the aftermath of military deployment

BACKGROUND

Several studies have documented factors related to increase in alcohol consumption in the context of stressful experiences. However, little is known about predictors of different courses of alcohol use in this context. This study aims to investigate diverse predictors and correlates of increase and decrease of average daily alcohol consumption (aDAC) in the aftermath of military deployment taking into account a variety of potentially relevant factors.

METHODS

N=358 soldiers were examined before (T1) and 12 months after return from deployment (T2) using standardized interviews. Change in aDAC was categorized into decreased (n=72), stable (n=215) and increased (n=71) aDAC.

RESULTS

Overall, aDAC did not change significantly between T1 and T2 (median change=0.0 g, inter quartile range=11.3g). Compared to stable aDAC, increase was characterized by a lower proportion of high-educated individuals (OR: 0.3 (0.1-0.7), p=0.008), lower rank (marginally significant: OR: 2.0 (1.0-4.1), p=0.050), and less acceptance (trend: MR: 0.97 (0.93-1.00), p=0.053). Correlates of increased aDAC were less social support (MR: 0.84 (0.71-0.99), p=0.043), more sleeping problems (MR: 1.15 (1.00-1.31), p=0.045) and more negative post-event cognitions following deployment (MR: 2.32 (1.28-4.21), p=0.006). Decrease in aDAC was predicted by lower PTSD symptom severity before deployment (MR: 0.34 (0.16-0.72), p=0.005) and less childhood emotional neglect (marginally significant: MR: 0.78 (0.60-1.00), p=0.050).

CONCLUSIONS

Increase and decrease in alcohol use after stressful experiences might have differential risk factors and correlates. Findings might stimulate future research that could result in improved measures to prevent increases as well as in interventions that could foster decreases in alcohol consumption in the context of stressful experiences.

Recognition and treatment of psychological disorders during military service in the UK armed forces: a study of war pensioners

PURPOSE

Little is known about the detection and treatment of psychological disorders arising during military service. We investigated whether personnel who developed disorders while serving in the UK armed forces came to the attention of medical services for these problems, received corresponding diagnoses, and were treated.

METHODS

For this retrospective record-based study 132 veterans in receipt of a war pension for psychological or physical problems received a lifetime diagnostic interview. Those with onsets of PTSD, depression, or alcohol abuse while in service were compared with those who never developed any condition or only developed it after discharge. Their medical records were inspected for contemporaneous contacts, diagnoses, and treatment.

RESULTS

PTSD and depression, but not alcohol abuse, were independently associated with mental health contacts while in service. The median time from PTSD onset to first contact was 1 month. Under half of personnel meeting criteria for these disorders received a corresponding diagnosis, and alcohol abuse was more likely to be recognised in the context of comorbid PTSD. PTSD was as well recognised in earlier as in later years covered by the study. Most personnel with disorders received treatment, and those treated were more likely to be medically downgraded or discharged.

CONCLUSIONS

War pensioners are more likely than not to have had their psychological problems acknowledged and treated while in service. The fact that these problems are still largely present 10 years later raises questions over the continuity of care associated with the transition to civilian life.

A new psychological intervention: "512 Psychological Intervention Model" used for military rescuers in Wenchuan Earthquake in China

OBJECTIVE

We sought to compare the efficacy of the "512 Psychological Intervention Model" (that is, "512 PIM", a new psychological intervention) with debriefing on symptoms of post-traumatic stress disorder (PTSD), anxiety and depression of Chinese military rescuers in relation to a control group that had no intervention.

METHOD

We conducted a randomized controlled trial with 2,368 military rescuers 1 month after this event and then at follow-up 1, 2 and 4 months later to evaluate changes in symptoms of PTSD, anxiety and depression based on DSM-IV criteria, respectively.

RESULTS

Baseline analysis suggested no significant differences between the study groups. Severity of PTSD, anxiety and depression decreased over time in all three groups, with significant differences between the groups in symptoms of PTSD (P < 0.01). Compared with the debriefing and control group, significant lower scores of PTSD and positive efficacy in improving symptoms of re-experiencing, avoidance and hyperarousal were found in the "512 PIM" group.

CONCLUSION

"512 PIM" was an effective psychological intervention for military rescuers in reducing symptoms of PTSD, anxiety and depression after a crisis.

Predicting future depression in adolescents using the Short Mood and Feelings Questionnaire: a two-nation study

BACKGROUND

Adolescence is a key life period for the development of depression. Predicting the development of depression in adolescence through detecting specific early symptoms may aid in the development of timely screening and intervention programmes.

METHODS

We administered the Short Mood and Feelings Questionnaire (SMFQ) to 5769 American and Australian students aged 10 to 15 years, at two time points, separated by 12 months. We attempted to predict high levels of depression symptoms at 12 months from symptoms at baseline, using statistical approaches based upon the quality, as well as the quantity, of depression symptoms present. These approaches included classification and regression trees (CART) and logistic regression.

RESULTS

A classification tree employing four SMFQ items, such as feelings of self-hatred and of being unloved, performed almost as well as all 13 SMFQ items at predicting subsequent depression symptomatology.

LIMITATIONS

Depression was measured using a self-report instrument, rather than a criterion standard diagnostic interview.

CONCLUSION

Further validation on other populations of adolescents is required: however the results suggest that several symptoms of depression, especially feelings of self-hatred, and being unloved, are associated with increased levels of self-reported depression at 12 months post baseline. Although screening for depression can be problematic, symptoms such as the ones above should be considered for inclusion in screening tests for adolescents.

Longitudinal health study of US 1991 Gulf War veterans: changes in health status at 10-year follow-up

The authors assessed changes in the health status of US 1991 Gulf War-era veterans from a 1995 baseline survey to a 2005 follow-up survey, using repeated measurement data from 5,469 deployed Gulf War veterans and 3,353 nondeployed Gulf War-era veterans who participated in both surveys. Prevalence differences in health status between the 2 surveys were estimated for adverse health indices and chronic diseases for each veteran group. Persistence risk ratios and incidence risk ratios were calculated after adjustment for demographic and military service characteristics through Mantel-Haenszel stratified analysis. At 10-year follow-up, deployed veterans were more likely to report persistent poor health, as measured by the health indices (functional impairment, limitation of activities, repeated clinic visits, recurrent hospitalizations, perception of health as fair or poor, chronic fatigue syndrome-like illness, and posttraumatic stress disorder), than nondeployed veterans. Additionally, deployed veterans were more likely to experience new onset of adverse health (as measured by the indices) and certain chronic diseases than were nondeployed veterans. During the 10-year period from 1995 to 2005, the health of deployed veterans worsened in comparison with nondeployed veterans because of a higher rate of new onset of various health outcomes and greater persistence of previously reported adverse health on the indices.
