Risk and protective factors for self-harm and suicide behaviours among serving and ex-serving personnel of the UK Armed Forces, Canadian Armed Forces, Australian Defence Force and New Zealand Defence Force: A systematic review

BACKGROUND

Self-harm and suicide behaviours are a major public health concern. Several factors are associated with these behaviours among military communities. Identifying these factors may have important implications for policy and clinical services. The aim of this review was to identify the risk and protective factors associated with self-harm and suicide behaviours among serving and ex-serving personnel of the United Kingdom Armed Forces, Canadian Armed Forces, Australian Defence Force and New Zealand Defence Force.

METHODS

A systematic search of seven online databases (PubMed, Web of Science, Embase, Global Health, PsycINFO, PTSDpubs and CINAHL) was conducted alongside cross-referencing, in October 2022. Following an a priori PROSPERO approved protocol (CRD42022348867), papers were independently screened and assessed for quality. Data were synthesised using a narrative approach.

RESULTS

Overall, 28 papers were included: 13 from Canada, 10 from the United Kingdom, five from Australia and none from New Zealand. Identified risk factors included being single/ex-relationship, early service leavers, shorter length of service (but not necessarily early service leavers), junior ranks, exposure to deployment-related traumatic events, physical and mental health diagnoses, and experience of childhood adversity. Protective factors included being married/in a relationship, higher educational attainment, employment, senior ranks, and higher levels of perceived social support.

CONCLUSION

Adequate care and support are a necessity for the military community. Prevention and intervention strategies for self-harm and suicide behaviours may be introduced early and may promote social networks as a key source of support. This review found a paucity of peer-reviewed research within some populations. More peer-reviewed research is needed, particularly among these populations where current work is limited, and regarding modifiable risk and protective factors.

Involving families in Veteran mental health care: Key considerations and recommendations

LAY SUMMARY

When Veterans seek and receive mental health care, their family members are often involved, directly or indirectly, in the process. Within Canada, recognition of the need for family-centred policies and practices is growing; however, family involvement in care is generally the exception rather than the rule. A recently developed Conceptual Framework advocates for a transformed mental health system centred on the experiences, needs, and preferences of Veterans and their families. This system may be well suited to a shift toward family-involved care. Drawing on this framework, this article makes a case for specifically involving families in Veteran mental health care. In particular, the crucial relationship between family and Veteran well-being is considered, as well as key benefits of and potential barriers to involvement. With these considerations in mind, some recommendations are made to move research, practice, and policy forward. These include 1) formalizing the definition of family, 2) developing a more comprehensive and nuanced understanding of Veteran families and their involvement, and 3) using educational and guidance materials to improve knowledge and build capacity. Despite potential limitations, these considerations and recommendations offer an opportunity to advance dialogue related to meaningful and safe involvement of families in Veteran mental health care.

Group identity, diffi cult adjustment to civilian life, and suicidal ideation in Canadian Armed Forces Veterans: Life After Service Studies 2016

Introduction: Suicide risk is higher in Canadian Armed Forces (CAF) Veterans than the Canadian general population (CGP). Suicidality is understood to be caused by incompletely clarified, complex interacting combinations of multiple factors. One of the precipitating factors for suicide is thought to be the social identity challenges known to occur in major life transitions. Methods: The 2016 Life After Service Studies survey representatively sampled Regular Force Veterans stratified by two release groups: earlier in 1998 to August 2012 ( n = 1,575) and more recently in September 2012 to 2015 ( n = 1,180). The linked dataset included socioeconomic and military characteristics and well-being indicators in multiple domains. Weak group identity was indicated by weak sense of local community belonging and/or not feeling part of a group with shared attitudes and beliefs. Associations were evaluated with multiple logistic regression. Results: Suicidal ideation, weak community belonging, and perceived difficult adjustment to civilian life were more prevalent in Veterans soon after release (September 2012 to 2015) than in Veterans released earlier (1998 to August 2012). Suicidal ideation and weak community belonging were more prevalent in the Veterans than in the CGP. In the more recently released Veterans, weak group identity was endorsed by the majority with suicidal ideation (93.3%). In adjusted regression models, mental health problems had the strongest association with suicidal ideation (adjusted odds ratio [AOR] = 13.4–79.3); however, weak group identity was moderately strongly associated with both difficult adjustment (AOR = 2.4–4.1) and particularly suicidal ideation (AOR = 3.8–9.0), independently of mental health problems. Discussion: Weak group identity was associated with difficult adjustment to civilian life and suicidal ideation in CAF Regular Force Veterans within 3.6 years after military release. These findings indicate the importance in suicide prevention of attending to social identity during transition to post-military life.

Life course well-being framework for suicide prevention in Canadian Armed Forces Veterans

Introduction: The risks of suicidality (suicidal ideation or behaviour) are higher in Canadian Armed Forces (CAF) Veterans (former members) than in the Canadian general population (CGP). Suicide prevention is everyone’s responsibility, but it can be difficult for many to see how they can help. This article proposes an evidence-based theoretical framework for discussing suicide prevention. The framework informed the 2017 joint CAF – Veterans Affairs Canada (VAC) suicide prevention strategy. Methods: Evidence for the framework was derived from participation in expert panels conducted by the CAF in 2009 and 2016, a review of findings from epidemiological studies of suicidality in CAF Veterans released since 1976, suicide prevention literature reviews conducted at VAC since 2009, and published theories of suicide. Results: Common to all suicide theories is the understanding that suicide causation is multifactorial, complex, and varies individually such that factors interact rather than lie along linear causal chains. Discussion: The proposed framework has three core concepts: a composite well-being framework, the life course view, and opportunities for prevention along the suicide pathway from ideation to behaviour. Evidence indicates that Veterans are influenced onto, along, and off the pathway by variable combinations of mental illness, stressful well-being problems and life events, individual factors including suicidal diathesis vulnerability, barriers to well-being supports, acquired lethal capability, imitation, impulsivity, and access to lethal means. The proposed framework can inform discussions about both whole-community participation in prevention, intervention and postvention activities at the individual and population levels, and the development of hypotheses for the increased risk of suicidality in CAF Veterans.
