The Relationship Between Mental Health Problems and Terrorism

Skip to Main Content.

Most people understand the experience of feeling anxious, sad, or unmotivated. For some, these feelings are temporary and fade with time; for others, they persist and cause significant distress, leading to changes in behavior, thinking, and emotion. When these changes begin to interfere with daily life, a mental illness [1] may be diagnosed. Mental illness is common—the National Institute of Mental Health estimates that one in five people in the United States live with a mental illness, or approximately Diagnoses can change over time and with treatment and, for many, symptoms can be reduced or managed.

Mental disorder

Mental and emotional health and well-being of youth is a serious health issue in Canada that has several implications in the field of youth crime prevention as well as for the juvenile justice system. According to the most recent reports of the MHCC , in , more than 7. The same report also reveals that more than , adolescents ages 13 to 19 lived with a mental health problem or illness in Canada MHCC, a.

For this group of population, substance use is the most frequent problem 9. These statistics show the need to better understand the links between mental illness and youth crime and the practices currently being used to serve the youth suffering from mental health disorders.

As such, the purpose of this report is to examine the Canadian knowledge concerning youth suffering from mental health disorders and their involvement in crime, with particular interest in the age group , to highlight the important correlations between mental health and some specific crime issues and to identify the knowledge gaps.

The following definitions provide clarification between the mental health concepts used in this report:. Footnote 2. Mental disorders are usually associated with significant distress in social, occupational, or other important activities. An expectable or culturally approved response to a common stressor or loss, such as the death of a loved one, is not a mental disorder. Socially deviant behavior e.

See appendix A for certain key mental health disorders. Positive mental health, however, can increase certain protective factors of individuals e. Using the Canadian Community Health Survey — Mental Health Footnote 4 , Statistics Canada compiled mental health contact with the Canadian police in an effort to examine the frequency of contact that those with and without disorders have with police Boyce, The data gathered was collected from people 15 years or older, and focused on specific reasons for police contact Footnote 5.

The findings of this survey demonstrate that Boyce, :. There is very limited information on the statistics of youth suffering from mental health disorders within the Correctional Service of Canada. However, the information is less limited in terms of adults within the correctional system. According to the Correctional Service of Canada and the Office of the Correctional Investigator, research on adult mental health statistics in Canadian penitentiaries indicates that:.

Risk factors can be defined as characteristics or experiences faced by an individual that increases the likelihood that a mental health problem will develop CCSA, Similar with the risk factors associated with a criminal trajectory, there is no single known risk factor for mental illness. Risk factors for future mental illnesses are thought to be the result of a complex interaction between biological genetics , economical e.

These factors will vary amongst individuals and across various stages of life. However, these risk factors can be mitigated by protective factors, which are seen as characteristics or experiences that reduce the likelihood a mental health problem will occur CCSA, ; examples of protective factors can range from strong family relationships to the youth having high self-esteem. No research study has been identified specifying and comparing the weight of risk and protective factors towards mental illness and how they interact to create an exponential effect.

The similarities of the risk factors between crime and mental illness create the idea that the two social issues may be related; an important statement that will be covered in the next section. It should be noted that the research provided in the following section does not pertain solely to youth, but is generalized for adults and youth.

When data is specific to youth, it is noted. However, another study shows that of all crimes committed by people with a serious mental disorder Footnote 8 in the US, only 7. Before any firm conclusions can be made on the association of all mental disorders and crime, more standardized research considering multiple risk factors should be conducted. In terms of the association between crime and comorbidity, a term used to describe multiple disorders present in one person simultaneously or sequentially National Institute on Drug Abuse, , there is also limited research, making it difficult to make formal conclusions about their relationship.

Studies have demonstrated that comorbidity does increase the odds of offending and violence Coker et al. In the Fazel study, it was found that the excess risk created by a schizophrenic disorder was mediated by the risks imposed by the substance abuse disorder, and that the risks associated with comorbidity closely resembled the risks of the population with only a substance abuse disorder Fazel et al. A similar finding was identified in the Coker study, as the majority of associations between psychiatric diagnoses and arrest-related crime became non-significant after conduct disorder diagnoses were removed from the sample Coker et al.

Further research is needed to make a formal conclusion on whether comorbidity increases the chances of offending for those suffering from disorders already heavily associated with crime, such as conduct or substance abuse disorders. Given that certain social issues have an impact on mental health and crime, we should consider the following social issues:. There are few studies that analyze the economic impacts of mental health problems, and techniques used to provide the cost estimations vary within these studies.

For example, over the past decade, four major Canadian studies have analyzed the costs of mental health problems and their implications on the economy on a national basis. Each study has used different cost components and methods health economists distinguish between three types of costs: direct expenditures; indirect or spillover costs; and intangible costs. Indirect costs were measured differently between studies, and expenditures in the justice system due to mental health problems and illnesses were not calculated MHCC, b.

These limitations considered, the following findings can help illustrate the relationship between mental health problems, illnesses, and the economy:. While the National Crime Prevention Strategy through its funding programs has supported the implementation of crime prevention programs helping populations, including youth suffering from mental health disorders, these programs are primarily meant for crime prevention purposes, and outcomes of these programs are not structured to measure indicators in the mental health domain.

However, because of the similarity between risk factors associated to crime and mental health disorders, it remains essential to promote prevention and early intervention for at-risk youth and their families. The potential cost savings of prevention programs can become extremely important in helping reduce the immense costs of mental health problems and mental illness.

Because many of these issues begin in childhood or adolescence, investing in mental health promotion, prevention and early intervention are identified as key areas Knapp et al. Of the utmost importance, access to the proper mental health services e. In , an estimated 1.

According to the CCSA, prevention initiatives that address the appropriate risk and protective factors can be effective at reducing substance abuse and mental health problems, and can even produce cost savings CCSA, ; Leschied, For this section, the core strategies identified by Leschied are directed at youth suffering from mental health disorders at-risk of offending, whereas other core examples are for youth suffering from mental health disorders.

Although these other examples have been effective in the field of crime prevention, the literature did not acknowledge their relation to prevention programs for youth who are suffering from a mental health disorder and are at-risk of crime:.

Several meta-analyses and reviews identified by the American Psychological Association APA Task Force on evidence-based practice with children and adolescents have shown that prevention programs for youth can reduce rates of later behavioural, social, academic, and psychological problems in the participants APA, Within these programs and other social development initiatives Footnote 16 , there have been evidence-based interventions for mental disorders that have been effective in preventing and treating affected youth.

For the purpose of this report, only few examples of evidence-based interventions Footnote 17 followed by pre-packaged programs are presented. Below are some examples of effective programs that have demonstrated positive results on improving mental health disorders as well as certain crime issues.

Due to a lack of outcome evaluations of these programs within the Canadian context, findings from these programs are from outcome evaluations that were conducted in the United-States Footnote 18 :. While delivering evidence-based interventions by appropriately trained staff is seen as a best practice, there are other interventions that have shown promising results in preventing and treating children and youth suffering from mental health disorders.

An example of that is the mentoring for children with emotional and behavioural disorders Footnote This mentoring intervention was designed to provide positive role models and supportive relationships that facilitate educational, social, and personal growth.

To conclude this section on prevention and intervention, it is important to mention the literature and programs oriented towards mental health promotion in children and youth. As such, increasing social connectedness, positive parenting style, physical health, and mental health literacy are just some examples of key domains where promotion programs, both from a public health as well as crime perspectives, can intervene positively. As seen from the information reviewed in this report, knowledge on the relationship between mental illness and youth crime is not conclusive.

The overrepresentation of mentally ill individuals in the correctional system may have been partially explained, however, the similarity of risk factors between youth with mental health disorders and youth at risk of crime is evidence of the potential weight carried by these experiences or life events when it comes to social perversion. We should also consider the link between mental illnesses and victimization; and that conduct and substance abuse disorders have a clearer association with criminality, but there is not enough information to clearly answer questions related to the relationship between mental illness and crime.

In order to begin answering these questions, there must be more research performed on the links between mental disorders and criminal activity. For example, this report could not make specific conclusions about youth crime and mental illness, as there is a lack of available studies concentrating on the link between mental illness and criminal activity in the context of youth.

Therefore, most of the conclusions made in this report needed to be broadened to mental illness and crime, regardless of age unless otherwise specified. Furthermore, factors such as the standardization of definitions within the paradigm of mental illness; studying symptoms of illnesses and their respective links to criminality; and the acknowledgement of the weight of risk factors of mental illness when linked to crime are also very important issues that need consideration in future research if we truly seek to deepen our understanding of the relationship between mental illness and criminal activity.

Finally, the presence of risk factors for criminal activity within the lives of youth suffering from mental disorders presents an opening for intervention before offending can take place. Combined with the proper services and intervention, crime prevention programs can positively impact the lives of these at-risk youth, giving them a chance to alter their future. Mental health disorders are grouped into categories in the DSM-V based on the similarity of symptoms, effects the disorders have on the person, and treatment response, among other things APA, Certain key mental health disorder categories for this report include:.

A mental disorder , also called a mental illness [3] or psychiatric disorder , is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. Many disorders have been described, with signs and symptoms that vary widely between specific disorders. The causes of mental disorders are often unclear. Theories may incorporate findings from a range of fields. Mental disorders are usually defined by a combination of how a person behaves, feels, perceives, or thinks. A mental disorder is one aspect of mental health.

However, these investigations are characterized by notable methodological weaknesses, and, consequently, this conclusion has remained tentative. Little is known about the criminality of intellectually handicapped people. The present study examined the relationship between crime and mental disorder and crime and intellectual deficiency in an unselected Swedish birth cohort followed up to age 30 years. Women with major disorders were five times more likely than women with no disorder or handicap to be registered for an offense and 27 times more likely to be registered for a violent offense. These subjects committed many serious offenses throughout their lives.

However, one shouldn't overlook the fact that most mentally ill people never commit violent crimes and schizophrenia is not a sufficient cause for violence. Besides.


The relationship between mental illness and violent offending has long been a subject of debate. As early as the fifth century BC the Greek philosopher Socrates is reported to have stated that a low crime rate in Athens indicated a low rate of mental disorder in the city. Although advocates for people with mental illness consistently argue that the rate of violence associated with these individuals is no greater than in the general population, recent studies are reporting modest causal connections between mental disorder and violent behaviour.

The link between mental health disorders and terrorism has long been a focus of academic research. Attention has focused most heavily on understanding the prevalence of mental disorders among those involved in terrorism. Evidence about the rates of mental health disorders among different categories of terrorists, including jihadist, right-wing and lone actors, is growing in strength. However, the causal relationship between mental health and engagement in terrorism remains unclear.

The Relationship Between Mental Health Problems and Terrorism

NCBI Bookshelf. The relationship between psychiatric illness and criminality has been the topic of intense debate and scrutiny in the recent past in light of multiple mass shootings in the United States. While the renewed focus and media attention on the importance of mental health in the aftermath of such tragedies is a positive development, the relationship between mental illness and criminality is too often conflated. The popular belief is that people with mental illness are more prone to commit acts of violence and aggression. The public perception of psychiatric patients as dangerous individuals is often rooted in the portrayal of criminals in the media as "crazy" individuals. A large body of data suggests otherwise. People with mental illness are more likely to be a victim of violent crime than the perpetrator.
