The relationship between traumatic experiences and posttraumatic stress disorder (PTSD) has been well documented in the literature. In recent years, studies have been focusing on the relationship between traumatic exposure and subsequent sleep problems and the role of sleep and sleep disorders in PTSD. For example, in a recent study utilizing a sample of 214 male Australian Vietnam veterans, Baird et al. (2018) found that those with PTSD reported a greater number of sleep-related problems compared to those without PTSD. Research has also shown that although sleep problems are not always resolved following PTSD treatment, PTSD symptoms are often reduced after sleep interventions (Koffel, Khawaja, & Germain, 2016). For example, Tamanna et al. (2014) reported that in a sample of 69 US veterans with a diagnosis of PTSD and obstructive sleep apnea, a sleep intervention improved not just the sleep-related symptoms, but also symptoms of PTSD. Existing research on the mechanisms underlying the relationship between trauma, sleep and PTSD is limited.
The aim of this PhD is to further investigate the relationship between trauma, PTSD and sleep using both primary data collection methods and secondary data analysis.
The study objectives will be to 1) Collect and identify appropriate data for analyses, and 2) determine the psychosocial mechanisms underlying the associations between key variables such as trauma, problematic sleep and PTSD. There will be several empirical studies involving quantitative statistical analysis. The study will seek to identify the specific pathways connecting trauma, PTSD and sleep problems, thus contributing to the literature on the mechanisms underlying these relationships. Network analysis and structural equation modelling will be employed. If appropriate data sources are collected and/ or available via secondary data sources, the investigation will be conducted both cross-sectionally and longitudinally.
This investigation will build the knowledge base on the mechanisms underlying the relationship between trauma, sleep and PTSD and will therefore be informative for the development of interventions and treatments aimed at alleviating both problematic sleep and PTSD.
