Publication: Review of posttraumatic cultural concepts of distress

Although not every human culture would recognize psychological terms as we use them in North America and Europe, every culture has ways of talking about how individuals feel, and every culture has terms that describe extreme and abnormal versions of these feelings. Cultural concepts of distress are those culturally-specific ways that people from within a given group express their psychological distress. For example, Cambodians talk about a khyal attack” as an experience whereby “wind” that flows naturally through the body (akin to chi in Chinese medicine) is blocked from exiting, causing problems that Western psychologists would call symptoms of panic attack (if you’re at all curious, you really should visit the website dedicated to explaining khyal attack).

A couple of colleagues and I recently published a review in Social Science and Medicine of the symptoms that are included in the various ways that different cultures think about the emotional distress following trauma. Our review included 55 studies and identified 116 different cultural concepts of distress. We categorized these concepts based on their symptoms (using hierarchical cluster analysis), and found that the 116 concepts could be described in four basic categories: (1) somatic dysphoria, which largely concerned bodily complaints; (2) behavioral disturbances, “odd” behavior (relative to cultural norms), (3) anxious dysphoria, which as its name implies included lots of anxiety; and (4) depression, which was surprisingly similar to depression as it appears in North American and European medicine. Notably, none of these groups of concepts looked like the psychological disorder that most mental health professionals in North America and Europe think of when they think about trauma — posttraumatic stress disorder, or PTSD.

Of course there are all sorts of limitations to our review, and some would argue that the way we categorized cultural concepts of distress using symptoms alone misses the point of the diversity of these concepts globally (which is broader concerning explanations for distress than it is concerning symptoms). Others would argue that PTSD is actually somewhere in the mix of concepts we reviewed. I’d like to think our review is a starting point for discussion of these issues, rather than a definitive answer to any of these questions.

One million Syrians in Lebanon: A portrait of daily stressors

The one millionth Syrian refugee in Lebanon was registered recently, and the United States’ National Public Radio commemorated the moment with a illuminating profile of life for Syrian refugees in Lebanon. Reporting from Beirut, NPR’s Alice Fordham reports that Syrians are struggling with multiple daily stressors — those stress-inducing events and conditions of varying degrees of severity that result in large negative effects on mental health.

Notably, of this four-minute radio piece it is not until the second half that Ms Fordham refers to trauma as a problem. Of course, for many Syrian refugees trauma and the emotional consequences of trauma are without a doubt a problem — but they are not the only problem. For psychologists and other mental health professionals the (mostly academic) debate surrounding the roll of common stressful events and conditions is still an unsettled question. For displaced persons, there is no debate at all.

In the interest of disclosure, I come to this debate not exactly as a neutral party: Ken Miller and I proposed a model for integrating daily stressors into conflict and post-conflict research a few years ago. For an alternative viewpoint, see the debate that followed.

Cognitive processing therapy for rape survivors in the Democratic Republic of Congo: Setting a new standard for post-conflict psychosocial care

Last week saw the publication of an important randomized control trial of cognitive processing therapy (CPT) for Congolese survivors of sexual assault in the New England Journal of Medicine (NEJM — and thanks, NEJM, for making the article available in full online). The fruit of intensive work by Judy Bass of Johns Hopkins, Jeannie Annan of the International Rescue Committee, Debra Kaysen of the University of Washington, and a host of others, this publication sets a new standard in the field of post-conflict mental health research and is welcome news for those affected by rape and other forms of sexual assault in low and middle-income (or, “LMIC”) war-affected settings.

The study involved almost 500 female survivors of rape in the eastern provinces of the Democratic Republic of Congo (DRC), an area of the world infamous for the absence of state control and an ongoing epidemic of sexual violence. Half were randomly assigned to a group-based version of CPT led by trained local counselors, half to generalized, patient-directed individual support and case management. Those attending CPT improved far more than those in the control group (although the latter also improved somewhat).

CPT has been shown to be effective for sexual assault survivors in several Northern, high-income countries, so that it was effective in the DRC may seem unsurprising. However, debates have raged in the past decade or so about the efficacy and effectiveness of doing psychotherapy in post-conflict settings that are not technically “post”-conflict and in populations with low-levels of education.

Prior research has suggested that short-term therapies may not be effective for populations exposed to ongoing trauma or multiple severe traumas. In our study, all villages reported at least one major security incident during the trial, including attacks, displacement due to fighting, and robbery by armed groups. In addition, there was concern that providing therapy to illiterate persons would be challenging. Our findings suggest that despite illiteracy and ongoing conflict, this evidence-based treatment can be appropriately implemented and effective.

This study shows that, with sufficient technical support, psychotherapy targeting trauma-related emotional problems can be delivered effectively in violence-affected LMICs as part of comprehensive psychosocial programs.

For a brief summary of the study and some commentary, see the related New York Times article from last Wednesday.

Global Mental Health Capacity Building at the 2012 ISTSS Annual Meeting

The annual meeting of the International Society for Traumatic Stress Studies (ISTSS), this year held in Los Angeles, wrapped up this weekend. This year’s theme, Beyond Boundaries: Innovations to Expand Services and Tailor Traumatic Stress Treatments, was in large part a response to a lack of global and cross-cultural perspectives at most ISTSS meetings. This year the planning was directed by two global mental health researchers, Debra Kaysen (University of Washington’s Global Mental Health program)and Wieste Tol (Johns Hopkins). Thanks to Debra and Wietse and their deputies (disclosure: the latter crowd includes yours truly), global perspectives were given the main stage. This was most obvious in two of the keynote addresses, one by global mental health luminary Vikram Patel (Kings College London School of Hygiene and Tropical Medicine and founder of Sangath) and longtime transcultural psychosocialist Joop de Jong (the founder of Transcultural Psychosocial Organization (TPO), professor at VU Amsterdam (which is the link), the University of Amsterdam, Boston University, Rhodes University in South Africa). (A request to academics from the blogosphere: If you’re going to hold appointments at multiple institutions, please host your own website — finding which link to post ain’t easy.)

In addition to the international perspectives, it was good to hear the issue of capacity building addressed head on. This was addressed in the keynotes, but it also had it’s own symposium. Theresa Betancourt (Harvard) chaired “Capacity Building in Low-Resource Settings,” and she laid out the issue as movement from “relief to resource,” which sums it up nicely. Speakers included Vikram Patel, Mary Fabri (formerly of Heartland Alliance in Chicago), and Joop de Jong. One of the key problems in global trauma practice is that mental health professionals from high income countries fly in to low and middle income countries (LMICs), do their thing for a few weeks or a few months, then fly out — leaving nothing in terms of increased ability to deal with the long-term issues related to disasters, let alone in terms of preparation for subsequent ones. Capacity Building in Low-Resource Settings was a discussion of how to guard against this all too frequent phenomenon.

Vikram Patel noted that a key to “scaling up” access to empirically supported treatments was identifying “primary tools of mental health… skilled human beings.” Patel is well-known for advocating “task-shifting” to “nonspecialists” — in the US we would call them paraprofessionals. His preferred term is “counselors,” as it is a now globally familiar term because of the widespread use of counselors for medication adherence issues in HIV/AIDS work and breastfeeding (the two global public health predecessors Patel looks to as models for global mental health). Important “soft skills” (i.e., non-content specific capabilities) that are basic to counseling include: engaging patients, assessing their mental health, suicide assessment, and knowing when to refer to more skilled professionals. The next stage of training involves advanced competencies that are disorder-specific, treatment-specific, and health context specific. Acquiring these competencies involves brief (a few days) classroom training and then moving trainees on to supervised field work (a few months). One of the major stumbling blocks to sustainability of any counseling program is the lack of consistent supervision. Patel has moved to a model that includes peer supervision with web-based (e.g., Skype) supervision done remotely. He noted that as very often counsellors do much more therapy than senior supervisors, peer supervision is often better than supervision by senior intervention researchers.

These themes were taken up by Mary Fabri and Theresa Betancourt in explications of their clinical interventions efforts with women in Rwanda and former child soldiers in Sierra Leone, respectively. A common problem was remote supervision. Certainly Skype and other web-based communication helps connect experienced clinicians, but connection speeds being what they are — or rather, what they are not — in many lower income countries, these are often simply not feasible. Fabri makes frequent trips, and Betancourt gets by with large telephone bills for weekly supervision.

Only just touched upon was how these programs, sustained largely with external funding, can be integrated into a countries’ national health strategies. One particularly sticky issue related to certification. Joop de Jong noted that “professionalizing” lay workers has historically been accompanied by nongovernmental organizations’ (NGOs) ignorance to local politics. The inability to engage established local authorities makes them (understandably) angry, which then leads to barriers to certifying those who have been working with NGOs following post-conflict periods (and may extend to them being unable to access educational resources as well). It is during these “post-post-conflict” periods where the sustainability of programs is proven.

Left untouched was the issue of building research capacity. But research capacity building was not left undiscussed at the conference. Later in the evening I had the good fortune to be at dinner with Marc Jordans, the Research Director at HealthNet TPO (also at Kings College London School of Hygiene and Tropical Medicine), who has made research capacity a priority. He explained the process as excruciatingly slow, as the challenges are largely educational. Here’s where the distinction between lower income countries and middle income countries is critical. Middle income countries (MICs — e.g., India, Peru) tend to have university systems, and therefore a pool of educated researchers in a field that uses research methods applicable to mental health research (.e.g, sociology, anthropology, public health); lower income countries (LICs — Sierra Leone, Nepal), however, often have one or two universities, and a very small pool of people with the base level research understanding to build upon. In essence, groups like HealthNet TPO are engaged in educational development, which, like all development work, is a multi-decade proposition. Jordans added, however, that the payoff for homegrown LIC researchers with a PhD is great, given that they are one of a few in their countries with the expertise and legitimacy to advise governmental and international organizations working in their regions.

Looking for graduate school applicants for research in forced migration, trauma and stress at Fordham University

Fall is graduate school application time, as many programs have application deadlines in October, November and December. I have recently moved to Fordham University’s Department of Psychology, and will be looking for graduate student applicants to the Clinical Psychology Division for the 2013 cohort. If you read this blog you know my experience and general research interests, so you know what kind of student researchers I am looking for. Current research projects include comparing the social networks of forced and voluntary immigrants and the health and mental health implications of network differences, measuring trauma and stress in different culturally-defined subgroups, and community-based participatory research with immigrant populations in general. If those are topics that interest you (and you want to get a PhD in Clinical Psychology), follow the links on the Clinical Psychology website and apply.

Deadline for 2013 applicants is Wednesday, December 5, 2012.

If you are not sure you want to commit to a PhD, but know that you are generally interested in psychology, program evaluation and related skills, please visit Fordham University’s MS in Applied Psychological Methods page. Fordham’s APM program is a relatively new course of study that draws heavily on it’s well-respected Psychometrics and Applied Developmental Psychology divisions within the Department of Psychology. Admissions are “rolling,” meaning that you can apply at any time and start the following semester. Students can be full- or part-time.

Two press pieces on the science (and anti-science) of PTSD in the military

The past weekend saw two articles in the popular press concerning PTSD among U.S. soldiers that are worth a read. First, the Seattle Times reported that the Army’s new PTSD screening guidelines fault the established screening tests designed to root out PTSD fakers. Why would anyone fake PTSD? The Army pays an average of $1.5 million in disability benefits per soldier (over his/her lifetime) with PTSD. It is estimated that 22 percent of returning soldiers have PTSD. The difference between those who have it and those who may be faking is no small chunk of change.

In part because of pressure by Senator Patty Murray (D-Washington) to investigate screening at the Madigan Army Medical Center (in Tacoma, Washington), the Army Surgeon General has issued new guidelines that criticize the use of the Minnesota Multiphasic Personality Inventory — or, MMPI, as most psychologists know it. The MMPI is one of the most venerated of psychological screening questionnaires, holding up pretty well in over 60+ years of research (it has been revised several times, most recently in 2008). At issue in this case is the MMPI’s “lie scale,” which has been shown to detect malingerers of various stripes in multiple studies.

According the the Seattle Times, the Army’s new policy “specifically discounts tests used to determine whether soldiers are faking symptoms of post-traumatic stress disorder. It says that poor test results do not constitute malingering.” Technically this is true; malingering scale scores on any normed test like the MMPI are associated with higher or lower probabilities of malingering, and not absolute certainty. Still, by throwing out the best tool they have to detect whether soldiers are malingering or not, what the Army really seems to be doing is trying to avoid appearing callous by relying on scientific methods.

Ironically, the same guidelines include empirically-based treatment improvements regarding medication:

The document found “no benefit” from the use of Xanax, Librium, Valium and other drugs known as benzodiazepines in the treatment of PTSD among combat veterans. Moreover, use of those drugs can cause harm, the Surgeon General’s Office said. The drugs may increase fear and anxiety responses in these patients. And, once prescribed, they “can be very difficult, if not impossible, to discontinue,” due to significant withdrawal symptoms compounded by PTSD, the document states.

Score one for research on meds, zero for research on screening questionnaires (or maybe: psychiatrists one, psychologists zero).

The second article of note wasn’t a report, but an editorial. Writing in the New York Times’ Sunday Review, Weill Cornell Psychiatrist Richard Friedman builds the case that one possible reason for the increase in cases of PTSD among returning soldiers from Afghanistan and Iraq is an increase in stimulants prescribed to them on the battlefield. With the help of the Freedom of Information Act, Dr. Friedman found that military spending on stimulants increased 1,000 percent over five years.

Stimulants do much more than keep troops awake. They can also strengthen learning. By causing the direct release of norepinephrine — a close chemical relative of adrenaline — in the brain, stimulants facilitate memory formation. Not surprisingly, emotionally arousing experiences — both positive and negative — also cause a surge of norepinephrine, which helps to create vivid, long-lasting memories. That’s why we tend to remember events that stir our feelings and learn best when we are a little anxious.

Since PTSD is basically a pathological form of learning known as fear conditioning, stimulants could plausibly increase the risk of getting the disorder.

Dr. Friedman goes on to explain the neurochemistry behind the proposed interaction of stimulants and trauma, review new research showing ameliorative effects of beta-blockers, and (appropriately) call for more transparency and more research on the topic.

More evidence that measuring local concepts of distress matters

The latest issue of Psychological Assessment includes an article by University of Pennsylvania postdoctoral research fellow (and soon to be Manhattan College Assistant Professor) Nuwan Jayawickreme that provides support for the use of locally developed distress measures in post-disaster settings that are beyond the cultural boundaries of Western psychology’s usually realm. Are Culturally Specific Measures of Trauma-Related Anxiety and Depression Needed? The Case of Sri Lanka provides empirical evidence suggesting that once locally-developed measures of posttraumatic distress are administered, administering measures of PTSD and depression (as defined by DSM-IV) does not provide any more useful information vis-a-vis an individual’s impairment of day-to-day functioning.

Developing psychological distress measures in non-Western disaster zones has been on the agenda of many in the disaster mental health field for over a decade now. The essential problem is that conceptualizations of mental health problems and the way that different people from different cultures express their distress vary widely. So, when mental health professionals need to assess individuals to see if they need treatment, they need a measure (questionnaire, survey, or some other standard measurement tool) that is sensitive to that population. How  are such tools to be developed? Jayawickreme explains:

Identifying such idioms first need to use ethnographic methods to understand how the social world interacts with the individual’s physical and psychological processes. Such ethnographic studies usually involve an in-depth examination of a specific culture’s conceptualization of a particular experience. Once the concepts and the idioms used by the community in question have been identified, questionnaires or inventories can be developed to assess these concepts, which are then validated using iterative statistical and field testing methods

And that’s what he did. And then he administered this measure, called the Penn/RESIST/Peradeniya War Problems Questionnaire (PRP-WPQ), the PTSD Symptom Scale (or PSS, a standard PTSD scale developed by trauma treatment luminary — and Jayawickreme advisor — Edna Foa) and the Beck Depression Inventory (the BDI, a standard measure of depression) to 197 Tamil Sri Lankans living in the war torn northern and eastern parts of the island. And then he looked at the incremental ability of the PTSD Symptom Scale and the Beck Depression Inventory to predict a measure of functional impairment.

Jayawickreme’s regression analysis showed what some of us have been talking about (and even publishing empirical results on) for a while now: Using measures of psychological distress with local populations that incorporate terms that they can understand is better at getting at the functional impairment due to this distress than using DSM-IV based measures.

The current findings provide support for the notion that sensitive measurement of  psychopathology in non-Western, war affected populations may require the development of instruments that incorporate local idioms of distress. As noted earlier, there are limited resources available for providers of psychosocial aid in non-Western, war-affected countries. Given the considerable needs of such populations, it may seem inappropriate to engage in what appears to be a costly and complicated process to develop measures incorporating local idioms of distress. The current results do indicate that the PSS and the BDI predict functional impairment to a substantial degree. However, the current results also suggest that measures incorporating idioms of distress may improve our ability over and above the established measures to identify those who are functionally impaired because of mental illness and who therefore need assistance.
