“…The participants' stories corroborate research studies (Pflanz and Sonnek 2002;Hoge, Castro et al 2004;Greenberg, Langston et al 2007;MacLean and Elder 2007;Pietrzak et al 2012) demonstrating that the soldier identity is impacted by deployment, and combat engagement in particular, which involves intense, high stakes attachments, exposure to loss of life and human suffering, and danger and threat as occupational hazards in combat (Litz et.al. 2015).…”

“…A Senate Inquiry (November 2016 ongoing) into suicide by veterans and ex-service personnel has highlighted the community concern with regard to the mental health of veterans and is identifying some of the hidden cost for combat veterans of service in a war zone. Lamperd (2016) In a comprehensive review of international literature on military service Australian researchers, Pietrzak, Harpaz-Rotem, Whealin and Southwick (2012) found compelling evidence that military deployment with combat exposure negatively affects the mental health of deployed personnel, especially the incidence of post-traumatic stress disorder (PTSD). Elsewhere, the impact of exposure in a war zone has been of particular interest in bio-medical and psychosocial studies.…”

This study explores the lived post-discharge experience of seven combat veterans of Australia's Middle East wars. The study has identified there is academic and popular recognition, interest in and knowledge about the process of socialisation into the military.However, there is a noticeable gap in material that explores the process of socialisation out of the military.Eighteen in-depth semi-structured interviews were conducted with the seven participants, some ranging over a twelve-month period. A phenomenological, interpretivist approach was taken using current literature, and input from military advisors, to help contextualise the participants' stories. Three themes emerged from the study as relevant to understanding the process of transition out of the military: the militarisation of identity, the impact of combat exposure as more deeply embedding the militarised identity and the challenges to this identity in negotiating the liminal space between military world and civilian world. The study identified that the challenges these veterans individually face on exiting the military, and the role their society has, collectively, in assisting their re-entry into the civilian world is not well understood.The study highlights that as well as understanding of the personal challenges these veterans face, the context of social recognition and response is a critical factor in their post-military adjustment in transition. Cultural dissonance, absence of place, unwitting stigma and marginalisation, and societal disavowal were characteristic of the experience of these men in their journey of transition from their military world to achieving re-assimilation in the civilian world. Civilian world accommodation and a system of repatriation to assist re-entry of combat veterans into the civilian world are identified as key aspects of reassimilation.iii

“…separated these three symptoms into a fifth factor, termed dysphoric-arousal, and found significant enhancement to model fit over the two four-factor models. This finding was then replicated in numerous subsequent studies (Armour et al, 2012;Contractor et al, 2013;Pietrzak, Tsai, Harpaz-Rotem, Whealin, & Southwick, 2012;Reddy, Andersond, Liebschutze, & Steind 2013;Wang et al, 2011). Therefore, although DSM-IV proposed a three-cluster model, and DSM-5 four factors, a five-factor model was eventually found to exhibit superior model fit.…”

“…The PTSD Checklist for DSM-5 (PCL-5, Blevins, Weathers, Witte, & Davis, 2012;Weathers et al, 2013) was utilized to compare the six-factor model to three four-factor models (i.e., the DSM-5 model, a DSM-5 dysphoria model, a DSM-5 dysphoric arousal model) and two five-factor models (i.e., a fivefactor revision of the DSM-5 model, a five-factor revision of a DSM-5 dysphoria model). This six-factor anhedonia model was a revision of a DSM-5 version of the five-factor dysphoric arousal model that had previously exhibited good fit with DSM-IV symptoms Wang et al, 2012;Pietrzak et al, 2012). As described by Liu et al (2014), this modification, which separated the negative alterations in cognitions and mood cluster into two separate factors, was based on theory and research indicating that negative and positive affect are distinct constructs (e.g., Watson, Clark, & Stasik, 2011).…”

The objective of the present research was to examine the underlying factor structure of posttraumatic stress disorder (PTSD) as conceptualized in the recently published fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013). A self-report measure of PTSD symptoms was administered to 258 trauma-exposed Iraq/Afghanistan war veterans. Confirmatory factor analysis was used to compare several different models of PTSD. Confirmatory factor analysis revealed that the best-fitting model was a six-factor model in which symptoms loaded onto the factors of intrusion, avoidance, negative affect, anhedonia, dysphoric arousal, and anxious arousal. These findings have important implications for ongoing conceptualization of PTSD and suggest that additional modifications to the diagnostic criteria for PTSD may still be warranted to more accurately reflect the underlying structure of PTSD symptoms.
