Posttraumatic stress disorder and its comorbidities among American Indian veterans

A Systematic Review of Trauma and Substance Use in American Indian and Alaska Native Individuals: Incorporating Cultural Considerations

INTRODUCTION

Disproportionate rates of psychiatric disorders, like substance use and posttraumatic stress disorders (SUD and PTSD), exist among American Indian and Alaska Native (AI/AN) individuals. This review examines substance use and trauma in existing AI/AN literature and utilizes an AI/AN-specific model to culturally inform the relationship between these factors and provide recommendations for future research.

METHODS

We searched three databases through April 2021 for peer-reviewed articles that examined substance use and trauma in AI/AN individuals.

RESULTS

The search identified 289 articles and of those, 42 were eligible for inclusion, including 36 quantitative and 6 qualitative studies. Rates of lifetime trauma exposure varied from 21 to 98% and were correlated with increased rates of SUDs. A dose response of traumatic events also increased the likelihood of an SUD among reservation-based AI populations. Factors from the Indigenist Stress Coping model included cultural buffers such as traditional healing and cultural identity, which aided in recovery from SUD and trauma, and social stressors like boarding school attendance, discrimination, and historical loss.

CONCLUSIONS

SUD and trauma are highly correlated among AI/AN individuals though rates of PTSD are lower than might be expected suggesting resilience. However, this pattern may not be consistent across all AI/AN groups and further research is needed to better explain the existing relationship of SUD and PTSD and relevant historical and cultural factors. Further research is needed to culturally tailor, implement, and validate PTSD and SUD assessments and treatments to ameliorate these health inequities.

Consistent Honor, Persistent Disadvantage: American Indian and Alaska Native Veteran Health in the National Survey of Veterans

Objective: To examine self-rated health and activities of daily living (ADLs) limitations among American Indian and Alaska Native (AI/AN) veterans relative to white veterans. Methods: We use the 2010 National Survey of Veterans and limit the sample to veterans who identify as AI/AN or non-Hispanic white. We calculated descriptive statistics, confidence intervals, and used logistic regression. Results: AI/AN veterans are younger, have lower levels of income, and have higher levels of exposure to combat and environmental hazards compared to white veterans. We found that AI/AN veterans are significantly more likely to report fair/poor health controlling for socioeconomic status and experience an ADL controlling for age, health behaviors, socioeconomic status, and military factors. Discussion: The results indicate that AI/AN veterans are a disadvantaged population in terms of their health and disability compared to white veterans. AI/AN veterans may require additional support from family members and/or Veteran Affairs to address ADLs.

Psychometric Properties of the Expanded Version of the Inventory of Depression and Anxiety Symptoms in a Turkish Population

The study examined psychometric properties of the Turkish version of the Inventory of Depression and Anxiety Symptoms-II (IDAS-II) in a Turkish sample. The sample consisted of nonclinical ( N = 931) and clinical ( N = 208) individuals. Confirmatory factor analysis showed that Turkish IDAS-II was similar to the original IDAS-II and supported the construct validity of the test. The Turkish IDAS-II showed good internal consistency, significant acceptable retest correlations, and was sensitive to changes over time. The Turkish IDAS-II also showed good convergent and discriminant validity in relation to the Beck Depression Inventory, the Beck Anxiety Inventory, the Mood Disorder Questionnaire, the Maudsley Obsessive Compulsive Inventory, the Panic Agoraphobia Scale, and the Post-Traumatic Stress Disorder Checklist-Civilian Version. Discriminant analyses revealed that the subscales of the Turkish IDAS-II significantly differentiated healthy controls from outpatients. The Turkish IDAS-II is a reliable and valid measure for assessing symptoms of depression and anxiety in Turkish-speaking participants.

Race/ethnicity and gender differences in mental health diagnoses among Iraq and Afghanistan veterans

Veterans who served in Operation Enduring Freedom (OEF; predominantly in Afghanistan) and Operations Iraqi Freedom and New Dawn (OIF and OND; predominantly in Iraq) and are enrolled in the VA are comprised of a growing cohort of women and higher proportions of racial/ethnic minorities than civilians. To compare rates of mental health disorders by race/ethnicity and gender for this diverse cohort, we conducted a retrospective analysis of existing records from OEF/OIF/OND veterans who were seen at the VA 10/7/01-8/1/2013 (N=792,663). We found that race/ethnicity was related to diagnoses of mental health disorders. Asian/Pacific Islanders (A/PIs) were diagnosed with all disorders at lower rates than whites, and American Indian/Alaska Native (AI/AN) males were diagnosed with most disorders at higher rates than white males. Research is needed to identify contributing factors to differential rates of diagnoses based on race/ethnicity and gender. A/PIs and AI/ANs have unique patterns of mental health diagnoses indicating they should be considered separately to present a comprehensive picture of veteran mental health.
