Exposure to traumatic events, Prevalence of Posttraumatic Stress Disorder and Alcohol Abuse in Aboriginal Communities
2010 PHC Research Conference: Paper abstract
Aims & rationale/Objectives
Aims and rationale of this study is to explore the relationship between exposure to traumatic events, prevalence of Posttrauamtic Stress Disorder (PTSD) and alcohol abuse in remote Aboriginal communities.
Indigenous residents of three twons and surrounds settlements in Western Austraslia were sellected for the purpose of this study. Combination of structured clinical interview and multiple survey questionaries - Composite International Diagnostic Interview (CIDI), and Impact of Events Scale (IES), Alcohol Use Disorder Identification Test (AUDIT) and Indigenous Trauma Profile (ITP) - were administered on 221 indigenous subjects aged 18 to 65 years who met inclusion criteria. Quantitative data were collected and analysed to establish the link between exposure to traumatic events, prevalence of PTSD and alcohol abuse/dependence.
Overwhelming, 97.3% (n=215) were exposed to traumatic events. Total of 55.2% (n=122) met the DSM-IV diagnostic criteria for PTSD. Of this group, 91% (n=111) of subjects that met diagnostic criteria for PTSD also met diagnostic criteria for alcohol abuse and dependence. Significant majority, 69% of subects who met diagnostic criteria for PTSD developed the disorder before the of age 21 years. Total of 96% (n=212) reported consuming a drink contain alcohol and 73.8% (n=163) met diagnostic criteria for alcohol use related disorders, abuse and dependence. The onset of alcohol abuse and dependece was before the age of 21 years in 67% of subjects.
Documenting and understanding traumatic events and prevalence of PTSD would lead to comprehensive understanding of issues affecting health and welfare of indigenous people and would help to develop effective strategies to address health concerns of this historically marginalised and traumatised population.
