BackgroundThe concept of Prolonged Grief Disorder (PGD) has been defined in recent years by Prigerson and co-workers, who have developed and empirically tested consensus and diagnostic criteria for PGD. Using these most recent criteria defining PGD, the aim of this study was to determine rates of and risks for PGD in survivors of the 1994 Rwandan genocide who had lost a parent and/or the husband before, during or after the 1994 events.MethodsThe PG-13 was administered to 206 orphans or half orphans and to 194 widows. A regression analysis was carried out to examine risk factors of PGD.Results8.0% (n = 32) of the sample met criteria for PGD with an average of 12 years post-loss. All but one person had faced multiple losses and the majority indicated that their grief-related loss was due to violent death (70%). Grief was predicted mainly by time since the loss, by the violent nature of the loss, the severity of symptoms of posttraumatic stress disorder (PTSD) and the importance given to religious/spiritual beliefs. By contrast, gender, age at the time of bereavement, bereavement status (widow versus orphan), the number of different types of losses reported and participation in the funeral ceremony did not impact the severity of prolonged grief reactions.ConclusionsA significant portion of the interviewed sample continues to experience grief over interpersonal losses and unresolved grief may endure over time if not addressed by clinical intervention. Severity of grief reactions may be associated with a set of distinct risk factors. Subjects who lose someone through violent death seem to be at special risk as they have to deal with the loss experience as such and the traumatic aspects of the loss. Symptoms of PTSD may hinder the completion of the mourning process. Religious beliefs may facilitate the mourning process and help to find meaning in the loss. These aspects need to be considered in the treatment of PGD.

Background The cumulative exposure to life-threatening events increases the risk for posttraumatic stress disorder (PTSD). However, over the course of evolutionary adaptation, intra-species killing may have also evolved as an inborn strategy leading to greater reproductive success. Assuming that homicide has evolved as a profitable strategy in humans, a protective mechanism must prevent the perpetrator from getting traumatised by self-initiated violent acts.Objective We thus postulate an inverse relation between a person's propensity toward violence and PTSD.Method We surveyed a sample of 269 Rwandan prisoners who were accused or convicted for crimes related to the 1994 genocide. In structured interviews we assessed traumatic event types, types of crimes committed, the person's appetitive violence experience with the Appetitive Aggression Scale (AAS) and PTSD symptom severity with the PSS-I.Results Using path-analysis, we found a dose-response effect between the exposure to traumatic events and the PTSD symptom severity (PSS-I). Moreover, participants who had reported that they committed more types of crimes demonstrated a higher AAS score. In turn, higher AAS scores predicted lower PTSD symptom severity scores.Conclusions This study provides first empirical support that the victim's struggling can be an essential rewarding cue for perpetrators. The results also suggest that an appetitive aggression can inhibit PTSD and trauma-related symptoms in perpetrators and prevent perpetrators from getting traumatised by their own atrocities.

Objectives of this study were to compare rates of mental health disorders in Rwandan genocide perpetrators with those of genocide survivors and to investigate potential predictors of symptoms of posttraumatic stress disorder (PTSD) and depression for both groups. We expected high rates of mental disorders in both study groups and hypothesized that symptom severity would be predicted by female gender, older age, lower level of education, higher level of trauma exposure, lower level of agreement to reconciliation, and the participation in killing. Structured clinical interviews were carried out with 269 imprisoned perpetrators (66% men) and 114 survivors (64% women). Significantly more survivors than perpetrators met symptom criteria for PTSD (46% vs. 14%) and suffered from anxiety symptoms (59% vs. 36%). A substantial proportion of both groups suffered from clinically significant depression (46% vs. 41%). PTSD severity in perpetrators was associated with trauma exposure, high levels of agreement to reconciliation, and no participation in killing; the severity of depression was associated with trauma exposure and no participation in killing. In the survivor sample, the severity of PTSD and depression were both correlated with female gender, trauma exposure, and low levels of agreement to reconciliation. Results suggest that both groups exhibit considerable psychiatric morbidity.

BackgroundDuring the Rwandan genocide of 1994, nearly one million people were killed within a period of 3 months.ObjectiveThe objectives of this study were to investigate the levels of trauma exposure and the rates of mental health disorders and to describe risk factors of posttraumatic stress reactions in Rwandan widows and orphans who had been exposed to the genocide.DesignTrained local psychologists interviewed orphans (n=206) and widows (n=194). We used the PSS-I to assess posttraumatic stress disorder (PTSD), the Hopkins Symptom Checklist to assess depression and anxiety symptoms, and the M.I.N.I. to assess risk of suicidality.ResultsSubjects reported having been exposed to a high number of different types of traumatic events with a mean of 11 for both groups. Widows displayed more severe mental health problems than orphans: 41% of the widows (compared to 29% of the orphans) met symptom criteria for PTSD and a substantial proportion of widows suffered from clinically significant depression (48% versus 34%) and anxiety symptoms (59% versus 42%) even 13 years after the genocide. Over one-third of respondents of both groups were classified as suicidal (38% versus 39%). Regression analysis indicated that PTSD severity was predicted mainly by cumulative exposure to traumatic stressors and by poor physical health status. In contrast, the importance given to religious/spiritual beliefs and economic variables did not correlate with symptoms of PTSD.ConclusionsWhile a significant portion of widows and orphans continues to display severe posttraumatic stress reactions, widows seem to constitute a particularly vulnerable survivor group. Our results point to the chronicity of mental health problems in this population and show that PTSD may endure over time if not addressed by clinical intervention. Possible implications of poor mental health and the need for psychological intervention are discussed.

A number of studies have demonstrated that symptoms of prolonged grief disorder (PGD) represent a symptom cluster distinct from bereavement-related depression, anxiety, and posttraumatic stress disorder (PTSD). The aim of the present study was to confirm and extend these findings using the most recent criteria defining PGD. The authors interviewed a total of 400 orphaned or widowed survivors of the Rwandan genocide. The syndromes were strongly linked to each other with a high comorbidity. Principal axis factoring resulted in the emergence of 4 different factors. The symptoms of depression, along with the cognitive, emotional, and behavioral symptoms of PGD, loaded on the first factor, symptoms of anxiety on the second factor, symptoms of PTSD on the third factor, and the separation distress symptoms of PGD on the fourth factor. This indicates that the concept of PGD includes symptoms that are conceptually related to depression. However, the symptom cluster of separation distress presents a grief-specific dimension that may surface unrelated to depressive symptoms.
