Identifying probable post-traumatic stress disorder: applying supervised machine learning to data from a UK military cohort

Background: Early identification of probable post-traumatic stress disorder (PTSD) can lead to early intervention and treatment. Aims: This study aimed to evaluate supervised machine learning (ML) classifiers for the identification of probable PTSD in those who are serving, or have recently served in the United Kingdom (UK) Armed Forces. Methods: Supervised ML classification techniques were applied to a military cohort of 13,690 serving and ex-serving UK Armed Forces personnel to identify probable PTSD based on self-reported service exposures and a range of validated self-report measures. Data were collected between 2004 and 2009. Results: The predictive performance of supervised ML classifiers to detect cases of probable PTSD were encouraging when compared to a validated measure, demonstrating a capability of supervised ML to detect the cases of probable PTSD. It was possible to identify which variables contributed to the performance, including alcohol misuse, gender and deployment status. A satisfactory sensitivity was obtained across a range of supervised ML classifiers, but sensitivity was low, indicating a potential for false negative diagnoses. Conclusions: Detection of probable PTSD based on self-reported measurement data is feasible, may greatly reduce the burden on public health and improve operational efficiencies by enabling early intervention, before manifestation of symptoms

Think Again – Supplying War: Reappraising Military Logistics and Its Centrality to Strategy and War

This article argues that logistics constrains strategic opportunity while itself being heavily circumscribed by strategic and operational planning. With the academic literature all but ignoring the centrality of logistics to strategy and war, this article argues for a reappraisal of the critical role of military logistics, and posits that the study and conduct of war and strategy are incomplete at best or false at worst when they ignore this crucial component of the art of war. The article conceptualises the logistics–strategy nexus in a novel way, explores its contemporary manifestation in an age of uncertainty, and applies it to a detailed case study of UK operations in Iraq and Afghanistan since 2001

From rhetoric to reality: which resilience, why resilience, and whose resilience in spatial planning?

This paper analyses contrasting academic understandings of ‘equilibrium resilience’ and ‘evolutionary resilience’ and investigates how these nuances are reflected within both policy and practice. We reveal that there is a lack of clarity in policy, where these differences are not acknowledged with resilience mainly discussed as a singular, vague, but optimistic aim. This opaque political treatment of the term and the lack of guidance has affected practice by privileging an equilibrist interpretation over more transformative, evolutionary measures. In short, resilience within spatial planning is characterised by a simple return to normality that is more analogous with planning norms, engineered responses, dominant interests, and technomanagerial trends. The paper argues that, although presented as a possible paradigm shift, resilience policy and practice underpin existing behaviour and normalise risk. It leaves unaddressed wider sociocultural concerns and instead emerges as a narrow, regressive, technorational frame centred on reactive measures at the building scale

Support needs and experiences of family members of wounded, injured or sick UK service personnel

© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved. Introduction When a service person has been wounded, injured or sick (WIS), family members may provide care during their recovery in an unpaid capacity. This may occur in diverse environments including hospitals, inpatient rehabilitation centres, in the community and at home. Method Thirty-seven family members of WIS personnel were interviewed regarding their support needs, family relationships and use of UK support services. Semistruc-tured, in-depth telephone interviews were used, with data analysis undertaken using a thematic approach. results ’Family member involvement’ was the main theme under which four subthemes were situated:’continuity of support’,’proactive signposting and initiating contact’,’psychoeducation and counselling’ and’higher risk groups’. Family members felt they might benefit from direct, consistent and continuous care regardless of the WIS person’s injury or engagement type, and whether the WIS person was being treated in a hospital, rehabilitative centre or at home. conclusion The findings of this study suggest that family members of WIS personnel value proactive, direct and sustained communication from support service providers. We suggest that families of UK service personnel may benefit from family care coordinators, who could provide continuous and consistent care to family members of WIS personnel
