Veterans who have served in military armed forces are often more likely to report having difficulties with anger and aggression. Despite this higher prevalence, our understanding of these phenomena in veterans is still emerging. The aim of this review is to explore research evidence into the prevalence of anger and aggression in veterans and to answer questions relating to associations between anger, aggression and other factors such as demographics and health conditions. Finally, the review summarises our latest understanding of the availability and effectiveness of treatment interventions.


Keywords: Anger, Military, Veterans, Mental health, Treatment


Anger and aggression are often reported to be areas of difficulty in military veteran populations [1]. Data suggests that individuals who have difficulties with anger and aggression may be more likely to have difficulties in social relationships, employment or day to day functioning [2].

Furthermore, anger and aggression can often present alongside comorbid health conditions, which may compound the difficulties they pose and significantly affect an individual’s well-being [3]. It is important to try to understand why anger and aggression can affect military veterans and what other factors might increase the chances of an individual being affected and in turn what impact it can have.

The aim of this review is to provide an overview of research into anger and aggression in military veterans. Within the review, anger is assumed to be primarily an emotional response and aggression a behavioral manifestation of this emotion. The review will focus on several key questions, each of which adds to our understanding of the risks of developing problems with anger and aggression. The questions relate to the prevalence of anger and aggression in military populations; exploring links between anger, aggression, demographic variables and co-morbid mental health conditions; and whether anger and aggression are linked to problematic behaviors such as offending and risk-taking. Finally, the review will summarize the latest research on treating anger and aggression in veterans.


High rates of anger have been reported both in serving military personnel [1] and veterans who are seeking help for their mental health [4-6] findings which have been found in several countries [1,7,8].

A recent study of UK veterans demonstrated that 74% of those who were seeking mental health treatment reported experiencing difficulties with anger. Furthermore, 28% reported frequent episodes of aggressive behavior [2].

Some authors have proposed hypotheses as to why veterans might be more prone to developing problems with anger and aggression. Morland et al. [9] suggested that because combat involves aggression, anger difficulties are more likely to develop in military veterans. Additionally, environmental and cultural factors in military settings might lead to aggressive traits being valued more than those of emotional sensitivity. In turn, anger as a primary emotional response can be highly adaptive in preventing vulnerable emotions such as guilt, sadness and remorse from weighing on individuals.


Research into UK veterans found that being younger, male and unemployed increased the likelihood of reporting difficulties with anger and aggression [2]. It may be that those who are not in employment suffer additional functional impairments as a result of anger and aggression which creates a barrier to seeking and maintaining employment. Furthermore, veterans were more likely to report problems with aggressive behavior if they did not feel supported by their family [2]. This suggests that close family support is a protective factor, preventing individuals from acting out on their anger. However, causality is difficult to establish, as being aggressive may have resulted in veterans being alienated from their families, rather than resulting from a lack of support.

In most research samples of veterans, the majority are male, which reflects the traditionally male-oriented nature of armed forces, although these trends are likely to change as more women take on military roles. Nevertheless, there may be some ideas from male psychology which also help to explain the prevalence of anger in veteran populations. For example, some research has posited that males with major depression are less likely to be given a diagnosis because they are more likely to display externalizing behaviors, e.g. aggression in response to distress, as opposed to more typical depressive symptoms, in a form of masculine variation of depression [10-12].



There is evidence of high rates of co-morbidity between anger and a range of mental health problems, in particular PTSD [3]. Longitudinal research has suggested that PTSD can predict the onset of anger difficulties, but that anger does not predict PTSD [13]. Feeling and expressing anger may serve as coping strategies for individuals who are overwhelmed by other trauma-based emotions such as guilt, shame, fear and hopelessness. As discussed above, angry reactions might be seen as more socially acceptable or might be more readily accessible to those who have served in the military, but in time this coping strategy becomes maladaptive.

Social processing theory offers an explanation as to why an individual who has experienced trauma might be more likely to respond with anger, as opposed to fear or sadness, for example. Taft et al. [14] reported on findings from studies looking at intimate partner violence (IPV) in individuals with PTSD. One study suggested that those with PTSD were more sensitive to shame-based content and to misinterpret neutral behavior in others as rejecting. These cognitive biases were related to higher rates of aggression and IPV [15]. Similarly, research of a small veteran sample showed that cognitive biases like hostile attributions mediated the relationship between PTSD and anger [16]. Social processing theory offers one way of understanding the link between PTSD and anger, which has implications for treatment, such as targeting cognitive biases.

Symptom network analysis has been used to investigate the nature of relationships between different primary and associate symptoms of PTSD [17], including anger. Findings suggested that anger was strongly associated with feelings of detachment. Detachment could also be described as emotional numbing, or avoidance of emotions and experiences. It is possible that those who are detached from PTSD-related emotions, e.g. fear, shame, sadness, are still able to express anger. Some authors have suggested that military personnel might express anger as a secondary emotion as it feels more empowering than the emotions that are underlying it [18].


As well as associations between anger and PTSD, studies of UK veterans have suggested that anger is also related to obesity [19]. Obesity was found to be far more prevalent among veterans seeking support for mental health difficulties and those who reported concurrent mental health difficulties, including anger, were more likely to be classified as obese according to their Body Mass Index (BMI). Other research has shown a relationship between other mental health difficulties and obesity [20] and it is possible that the relationship between anger and obesity is explained by this wider association. There may be several explanations for this link, including illness-related factors (e.g. lack of motivation), lifestyle factors (e.g. diet) or medication side-effects [19]. Again, causality is difficult to establish from this research.

Brain injury

Research has also shown that veterans who report having a traumatic brain injury (TBI) were more likely to describe significant difficulties with anger [21]. Aggression is one of the most common consequences of traumatic brain injury, with prevalence previously reported as high as 34% [22]. Studies of individuals with TBI have shown that verbal aggression is particularly high, but that physical aggression is less common [23,24]. This relationship might be explained by reduced functioning in areas of the brain involved in impulse control or reasoning. However, aggression after a TBI has also been linked with reductions in psychosocial functioning (including functional impairment and reduced engagement in therapy), activities of daily living, as well as depression, which might partly explain the association with anger and aggression too.

These studies suggest that anger in veterans rarely presents in isolation and instead presents alongside numerous other factors. The challenge for those seeking to help individuals with anger is teasing apart the extent to which anger is the primary target problem, as opposed to an additional secondary symptom of something else, e.g. PTSD.


Research has suggested that anger and aggression have been linked to problematic behaviors in veterans. For example, network analysis has found anger to be closely linked to reckless and self-destructive behavior [17]. One such self-destructive behavior could be alcohol misuse. Recent findings have suggested that treatment-seeking veterans who report anger difficulties are also more likely to report alcohol misuse, alcohol dependency and alcohol-related harm [25]. Alcohol misuse is also linked to violent offending in military personnel post-deployment [26]. UK Government statistics show that veterans form the largest single occupational group within the prison and probation services and that they are more likely to have committed a violent or sexual offence than offenders who have not served in the military. Veteran status has been associated with increased levels of interpersonal violence, motoring offences, anxiety disorders and hazardous drinking patterns [27].

Veterans have also been found to have higher rates of risk-taking behaviors, in particular fighting, heavy drinking, smoking and risky driving. Fighting was found to be six times higher in this sample of veterans compared to previous findings of military personnel [26]. Given the high proportion of PTSD within this population group, this high fighting prevalence may be due to neurobiological changes in the brain following trauma and difficulties with emotion regulation [26].


Recent research has systematically reviewed 13 meta-analyses of anger treatments [28]. There was good evidence supporting the effectiveness of anger and aggression interventions, such as CBT and other treatments which have been less widely studied, such as family therapy, psychodynamic therapy and relaxation. The authors note that psycho educational anger classes have very little evidence, despite being commonly used as interventions. They added that CBT-based interventions are often not consistent in their content, which makes it hard to know what components, i.e., cognitive, behavioral, etc. are effective for which populations. Whilst some have questioned whether anger and aggression are necessarily linked, evidence does suggest that the treatment of anger can help to reduce aggression, suggesting that they are related [29,30].

Dialectical Behavior Therapy (DBT) is an adapted form of CBT which has been used widely in the treatment of Borderline Personality Disorder (BPD) and self-harm or suicidal behaviors [31], with a primary focus on emotional disturbance. DBT has been trialed as an anger intervention and one review compiled evidence from 21 studies [32]. DBT typically comprises four core elements: mindfulness, distress tolerance, emotion regulation and interpersonal effectiveness. Results of the review suggested DBT-based interventions for anger show promising reductions in anger and aggression. The review also showed that participants who were experiencing anger alongside other mental health difficulties showed reductions in anger and other psychiatric symptoms, e.g. BPD [33-35]. The authors suggested that this could mean that a DBT approach could be useful for individuals experiencing anger in the context of other psychological difficulties and that reducing anger might accelerate treatment effectiveness for co-morbid problems.

Residential anger management programmes offer a high-intensity alternative to outpatient treatments. In the UK, a two-week intervention has been trialed with veterans, combining elements of CBT and DBT in group and 1:1 environments. Findings have demonstrated reductions in anger in those concurrently experiencing PTSD symptoms [36]. This may have benefits for those who go on to access trauma-focused interventions, as the presence of co-morbid psychological problems can reduce the effectiveness of PTSD treatments [37].

Pharmacological interventions have also been researched in the general population but with few using veteran samples. For example, a small-scale study suggested that a low dose of risperidone was associated with reductions in aggression, irritability and some PTSD symptoms [9,38]. Evidence from general population samples suggests other pharmacological interventions can reduce anger and aggression, such as selective serotonin re-uptake inhibitors (SSRIs), e.g. fluoxetine [39]. However, some authors have discussed how treatment interventions, both pharmacological and psychological, can be have less efficacy in veteran samples compared to the general population [40].


There is increasing evidence for the prevalence of anger and aggression-related difficulties in military veterans, as well as different relating factors which increase the chance of these difficulties presenting. Anger and aggression are strongly linked to the presence of other co-morbid health difficulties, which poses a challenge in understanding an individual’s difficulties and where to intervene. However, it also presents an opportunity for applying different interventions, as reductions in anger, for example, can lead to improvements in other areas or make it easier to access further treatments. Anger and aggression in veterans is linked to several problematic behaviors which may compound an individual’s mental health. Nevertheless, our understanding of the effectiveness of different treatments is improving. Treatments using different CBT and DBT models have been found to be effective, but future interventions might look to more integrative approaches as a way of advancing treatments. Either way, more robust, longitudinal and controlled trials would be of benefit to the field.
