Baksbat (Broken Courage): The Development and Validation of the Inventory to Measure Baksbat, a Cambodian Trauma-based Cultural Syndrome of Distress

The dose-effect relationships of cumulative trauma to the psychiatric symptoms of major depression and post-traumatic stress disorder (PTSD) in a community study of Cambodian survivors of mass violence were evaluated. In 1990, a survey of 1000 households was conducted in a Thai refugee camp (Site 2) using a multi-stage random sampling design. Trauma history and psychiatric symptoms were assessed for two time periods. Analysis used linear dose-response regression modelling. 993 Cambodian adults reported a mean of 14 Pol Pot era trauma events and 1.3 trauma events during the past year. Symptom categories of depression, PTSD, dissociative and culturally dependent symptoms exhibited strong dose-effect responses with the exception of avoidance. All symptom categories, except avoidant symptoms, were highly correlated. Cumulative trauma continued to affect psychiatric symptom levels a decade after the original trauma events. The diagnostic validity of PTSD criteria, with the notable exception of avoidance, was supported. Inclusion of dissociative and culturally dependent symptoms increased the cultural sensitivity of PTSD.

Research into postconflict psychiatric sequelae in low-income countries has been focused largely on symptoms rather than on full psychiatric diagnostic assessment. We assessed 3048 respondents from postconflict communities in Algeria, Cambodia, Ethiopia, and Palestine with the aim of establishing the prevalence of mood disorder, somatoform disorder, post-traumatic stress disorder (PTSD), and other anxiety disorders. PTSD and other anxiety disorders were the most frequent problems. In three countries, PTSD was the most likely disorder in individuals exposed to violence associated with armed conflict, but such violence was a common risk factor for various disorders and comorbidity combinations in different settings. In three countries, anxiety disorder was reported most in people who had not been exposed to such violence. Experience of violence associated with armed conflict was associated with higher rates of disorder that ranged from a risk ratio of 2.10 (95% CI 1.38-2.85) for anxiety in Algeria to 10.03 (5.26-16.65) for PTSD in Palestine. Postconflict mental health programmes should address a range of common disorders beyond PTSD.
