Anger, PTSD, and the nuclear family: A study of Cambodian refugees
Introduction
The current study investigates anger, specifically the anger of traumatized Cambodian refugees directed toward family members. All patients attended a psychiatric clinic in Lowell, MA, USA, and all were survivors of the Pol Pot period. The Pol Pot genocide occurred from 1975 to 1979, during which about 1.7 million of Cambodia's 7.9 million people died, a quarter of the population; death resulted from execution, starvation, overwork, and illness. Owing to having survived these and other traumas (e.g., living in dangerous refugee camps), Cambodian refugees have high rates of psychiatric disorders. In one study, 56% of the Cambodian refugees attending an outpatient psychiatric clinic had PTSD, and the PTSD scores were quite high (on the Clinician-Administered PTSD Scale; Hinton, Chhean, Pich, Pollack, et al., 2006); in another study, 60% had panic disorder (Hinton, Ba, Peou, & Um, 2000).
Anger appears to play an important role in the psychopathology of traumatized Southeast Asian refugees. In one study, Southeast Asian refugees with PTSD had significantly higher scores on the Anger Reaction Index, including higher levels of both expressed and experienced anger (Abe, Zane, & Chun, 1994). In a study of Vietnamese refugees using the Symptom Checklist (SCL), of the 9 items that were able to differentiate between patients with and without PTSD, 3 were anger items (Hauff & Vaglum, 1994). In a study of Cambodian refugees attending a psychiatric clinic, the patients had elevated rates of anger and much anger associated autonomic arousal, with 58% of the patients with PTSD having anger episodes causing enough somatic arousal symptoms (e.g., palpitations) to meet panic-attack criteria; and they had many catastrophic cognitions about the somatic symptoms induced by anger, including culturally specific concerns, such as that the neck vessels might rupture (Hinton, Hsia, Um, & Otto, 2003).
In the study of anger among Cambodian refugees discussed above (Hinton et al., 2003), the authors did not investigate the cause of anger episodes, or whether anger triggered recall of trauma events. Our clinical experience with Cambodian refugees would suggest that anger is often directed toward spouse and children, that the anger is severe (e.g., associated with extreme somatic arousal: palpitations), and that the anger often triggers trauma recall. Anger is a one of the 14 DSM–IV diagnostic criteria for PTSD (First, Spitzer, & Gibbon, 1995), and trauma's main impact on local social worlds may be through anger. The few studies that have examined the effect of anger among trauma victims at the level of the family have only investigated anger directed toward a spouse (see, e.g., Taft, Street, Marshall, Dowdally, & Riggs, 2007); none have examined anger directed toward children. The lack of studies of anger's effect on the family unit of traumatized populations represents a major gap in the literature.
To address this gap in the literature, the current study examines the anger of Cambodian patients directed toward family members, specifically nuclear family (NF) members, here defined as the “significant other” (i.e., spouse or boyfriend/girlfriend) and children. To investigate family-directed anger, we developed an approach informed by the psychological literature on anger (Berkowitz, 1999, DiGiuseppe and Tafrate, 2007, Novaco and Chemtob, 2002) and anthropological theories of emotion (Shweder, 2004). In addition, the approach was influenced by the literature demonstrating that “generational dissonance” (Smith-Hefner, 1999), a difference in acculturation between the first and second generation, may be a key issue in Cambodian diaspora communities, and by our clinical experience showing a linguistic gap to be a key problem in conflict resolution.
Based on this literature review and our clinical experience, we undertook a multidimensional, psycho-sociocultural examination of NF-type anger of Cambodian refugees attending a psychiatric clinic. We determined the number of patients having experienced anger toward NF members in the previous month, whether the source of anger was a significant other or a child, asked the reasons for becoming angry at a NF member, and assessed anger along several dimensions (viz., intensity, frequency, somatic arousal, and acting-out behaviors). To further profile anger episodes, we also investigated whether anger resulted in trauma recall, the content of that trauma recall, and whether anger caused concerns about bodily dysfunction. If the conflict involved a child, we examined whether the child's lack of proficiency in the Cambodian language, conjoined with the parent's lack of English ability, impeded conflict resolution. And we asked patients what they did to gain relief from the anger episode. We also determined the rate of PTSD, its association with NF-directed anger, and whether the effect of anger on PTSD severity resulted in part from anger-associated trauma associations and catastrophic cognitions. [We performed these regression analyses, for one, because previous studies of Cambodian refugees indicate that the effect of panic attacks on PTSD severity results in large part from trauma recall triggered by those panic attacks (Hinton, Chhean, Pich, Um, et al., 2006), and anger episodes, which often trigger strong arousal, would be expected to demonstrate a similar pattern; and second, because catastrophic cognitions about the somatic symptoms in anger episodes would be expected to result in panic-disorder-like panic attacks and a sense of vulnerability, both of which have been shown to worsen PTSD (Clark, 1999, Hinton et al., 2006, Hinton and Good, 2009)].

Participants
All patients received treatment at a psychiatric clinic in Lowell, MA, home to approximately 30,000 Cambodians, the second largest Cambodian population in the United States. Upon first presenting to the clinic, all patients have PTSD, with comorbid anxiety and depression; very few have bipolar or schizophrenia disorder (<5%). The vast majority (over 90%) are unemployed, many receiving disability benefits. For the current study, we aimed to obtain a sample of at least 60 patients with NF-type
Demographic information
Of the surveyed patients, most were women: 72.7% (104/143). The mean age of patients was 50.1 (SD = 8.2), range 39–75. Forty percent (57/143) of the patients had a significant other (SO). The rate of having a SO did not differ significantly by gender. Of the 57 patients with a SO, 68% (39/57) had been married according to the traditional Cambodian wedding ceremony but only 14% (8/57) were legally married, with all those legally married also having married according to the traditional ceremony.
Discussion
Among Cambodian patients attending a psychiatric clinic, the current study documented the frequency and clinical importance of anger directed toward NF members. We found that NF anger was frequent and often directed toward children, and that NF-type anger was severe, for example, 71% of the anger episodes met panic-attack criteria on the basis of somatic arousal, and the anger episodes often resulted in trauma recall and catastrophic cognitions. We also discovered that language barriers between
