This paper focuses on network analysis as a way of studying psychological disorders in UK military veterans.
Network analysis is a relatively new methodology for studying psychological disorders. It focuses on the associations between individual symptoms which are hypothesized to mutually interact with each other. The current study represents the ﬁrst network analysis conducted with treatment-seeking military veterans in UK. The study aimed to examine the network structure of posttraumatic stress disorder (PTSD) symptoms and four domains of functional impairment by identifying the most central (i.e., important) symptoms of PTSD and by identifying those symptoms of PTSD that are related to functional impairment. Participants were 331 military veterans with probable PTSD. In the ﬁrst step, a network of PTSD symptoms based on the PTSD Checklist for DSM-5 was estimated. In the second step, functional impairment items were added to the network. The most central symptoms of PTSD were recurrent thoughts, nightmares, negative emotional state, detachment and exaggerated startle response. Functional impairment was related to a number of diﬀerent PTSD symptoms. Impairments in close relationships were associated primarily with the negative alterations in cognitions and mood symptoms andimpairments inhomemanagementwere associatedprimarily withthe reexperiencingsymptoms. Theresults are discussed in relation to previous PTSD network studies and include implications for clinical practice.
