Unique PTSD/Depression Risk Factors for Blacks, Latinos
While it is known that chronic disease and mental health issues disproportionately affect low-income African-Americans, Latinos, and Hispanics, evidence explaining why this occurs has been scant.
Two new studies by the University of California, Los Angeles (UCLA) Center for Culture, Trauma and Mental Health Disparities now shed light on the causes and impacts of this disparity.
The first study analyzed certain types of negative experiences that may affect low-income African-Americans and Latinos. It found five specific environmental factors, which the researchers call “domains,” that can predict adult depression, anxiety, and post-traumatic stress disorder.
This study appears online in the journal Psychological Trauma.
In the second study, published online by the journal Psychological Assessment, researchers used the same five domains to develop a new screening tool for use in clinical settings.
The instrument, called the UCLA Life Adversities Screener, or LADS, is a brief questionnaire that can help providers offer more accurate treatment for stress and trauma.
The five domains identified in the first study are:
- Experiences of discrimination due to racial, ethnic, gender, or sexual orientation;
- A history of sexual abuse;
- A history of violence in the family or from an intimate partner;
- A history of violence in an individuals’ community;
- A chronic fear of being killed or seriously injured.
The researchers explain that the effects of these experiences are cumulative and their impact accrues over a person’s lifetime. As a result, the downstream effects are significant.
“The costs to society of these life experiences are substantial,” said Hector Myers, a former UCLA psychology professor and first author of the Psychological Trauma study.
“We know there is a poorer overall quality of life, a loss of productivity, greater social dependency, disability, health and mental health care costs, and early mortality as a result of repeated experiences of stress and trauma.”
In the first study, researchers asked 500 low-income African American and Hispanic men and women to self-report various measures of stress and mental health, including experiences of discrimination, childhood violence, poverty, and trauma.
Investigators then used a statistical method — structural equation modeling — to discover a correlation between the cumulative burden of these adversities and the likelihood the subjects would later experience psychological distress.
Researchers also found that the greater people’s overall burden of these experiences over their lifetime, the greater the likelihood that they would experience more severe symptoms of depression, anxiety, and PTSD.
“Unfortunately, much of the psychological distress stemming from chronic life stress and trauma remains undetected and untreated,” said Gail Wyatt, a professor of psychiatry and a senior author of both studies.
“Only a small proportion of individuals with psychological distress are identified in health care settings, and a smaller fraction of those ever receive appropriate treatment, especially for the experiences of discrimination,” said Wyatt.
“We talk about being discriminated against, but people don’t learn how to cope with it effectively throughout their lives. If they don’t manage it well enough, the consequences can be long-lasting and life-threatening.”
The second study was led by first author Honghu Liu, a professor in the UCLA School of Dentistry. Working with the five domains, the researchers used regression modeling — a statistical process for estimating relationships among variables — to develop the screening tool or LADS.
The instrument consists of a set of questions health care providers can use to screen patients for the effects of adversity and trauma.
“Given the utility and ease of use, LADS could be effective as a screening tool to identify ethnic and racial minority individuals in primary care settings who have a high trauma burden, and who need more extensive evaluation,” said Liu, who is an expert in the design of research studies, data analysis and statistical modeling.
“We feel it will capture experiences that could be missed with current screening approaches. This could optimize affordable care as it strives to improve prevention of mental health problems.”
Researchers believe emerging health policy, that is, the Patient Protection and Affordable Care Act or Obamacare will help professionals identify many who have not been assessed for the adversities and trauma that can affect mental health needs.
Indeed, many of the 16 million patients who have gained insurance under the ACA could benefit from being screened and assessed.
“The next step is to offer individuals tools to more effectively cope with the adversities and trauma that they endure,” says Wyatt.
“One of the advantages of affordable primary care is that we will have the opportunity to offer skills for people who have not had mental health care for those experiences, one day soon. They will no longer have to manage on their own.”
