Trauma and grief often co-occur, however the degree to which these two constructs overlap or are distinguishable is still poorly understood. Homicidally bereaved individuals are exposed to both trauma and loss-related stressors. Previously collected data were used to explore the relationship between trauma and grief components in homicide bereavement distress, and whether homicide bereavement distress was distinguishable from that of other adverse life events. The overarching research question for this study was: Are event and loss related distress distinguishable among siblings bereaved by homicide,1 as measured on the Impact of Event Scale-Revised (IES-R)? Data from 67 individuals who lost a sibling to murder while growing up (Murder Group) were compared to data from 80 comparison individuals who grew up with a sibling (Comparison Group), but who had no experience of homicide bereavement. A cross-sectional, iterative survey design using group comparisons was used. Participants in the Murder Group reported significantly higher levels of current subjective distress compared with the Comparison Group. Among the siblings bereaved by the homicide loss of a sibling, event- and loss-related subjective distresses were highly and significantly correlated. In addition, both decreased significantly over time (years), and at similar rates. Preliminary findings from exploratory analyses of the IES-R provide insight into the avoidance, intrusion, and hyperarousal components of subjective distress following homicide loss. Findings will inform understanding of the overlap, and distinguishing features, of concurrent trauma and grief. Implications for theory and empirical research are noted, and recommendations for future research and counselling practice are discussed. / Graduate / 2017-09-13 / simpson9@uvic.ca

This study examined the validity of the South African Police Service (SAPS) multiple stressor intervention. The multiple stressor was developed for members of their specialised units to address Post Traumatic Stress Disorder (PTSD). Unfortunately, the SAPS multiple stressor intervention lacks scientific evidence to support its possible effectiveness in addressing PTSD. In the current study a deployment and intervention group was compared which employed a pre- test post-test design. The Davidson Trauma Scale and the Revised Impact of Event Scale measured PTSD globally, but also the PTSD dimensions of Intrusion, Avoidance/Numbing, and Hyperarousal. The Wilcoxon signed rank test results indicated that the intervention and deployment was both effective in addressing PTSD although the intervention group revealed the greatest improvement in their overall PTSD scores. The intervention group made significant progress in dealing with all three PTSD symptoms while the deployment group made less progress with their Intrusion and Avoidance/Numbing symptoms, but made significant progress with their Hyperarousal symptoms. The Mann-Whitney u test revealed no significant differences between the post intervention test scores of the two groups, either globally or on the three PTSD dimensions. It appears that deployment was just as effective as the multiple stressor intervention in addressing PTSD. / Psychology / M.A. (Psychology)
