The Risk Of Criminal Victimisation In Mental Health Outpatients

The majority of scientific research carried out in mental health has focused on those with mental illness being those who commit violent acts against others.  An understandable research stream in order to gain information about why violence can occur in mental health and how interventions or preventative measures may help in these types of cases.

However, there are a number of research studies which indicate that it is in fact those with mental illness who are more likely to be the victim of a violent crime.  For a person with mental illness, experiencing criminal victimisation through verbal abuse or physical violence can exacerbate their symptoms and push them to require further support from mental health services.

Crime victimisation and mental health has traditionally focused on people who suffer with the most severe mental health problems. Those with more common issues, such as depression and anxiety, and who are generally outpatients of mental health units has been largely overlooked.

Studying Criminal Victimisation

Researchers from the Netherlands aimed to fill this gap by studying the self-reports of victims who had experienced abuse and victimisation because of their mental illness. They wanted to compare the levels of violent and non-violent criminal victimisation among mental health sufferers with a range of diagnoses, with the levels seen in the general population.

A study published in 2015 by Meijwaard and his colleagues identified 300 mental health outpatients in Amsterdam.  102 of these patients had a depressive disorder, 106 a substance use disorder and 92 with a severe mental illness.

They were all interviewed using a National Crime Victimisation Survey completed with trained psychology research associates between 2011 and  2012. A further 10’865 people from within the community with no mental health issues were matched to the mental health group sample and used as controls for comparison.

To give this research a framework to work within, a formal diagnosis in accordance with the Diagnostic and Statistical Manual of Mental Disorders (DSM) was a criterion for participants to be included in the study.  People engaging in outpatient mental health care within the community with a primary diagnosis of depressive disorder, substance misuse disorder or severe mental illness were included.

Severe mental illness included diagnosis of schizophrenia and bipolar disorder. All participants were over 16 years of age and gave their written consent to take part in the study. For the control subjects, the same questionnaire was sent out to them in the post or via the internet and those who did not respond were telephoned or visited face to face in order to complete the questionnaire.

A number of crimes within victimisation, from violent crimes, threats and assaults, to property crimes, burglary, car theft, pickpocketing and robbery were examined with a view to discover how many people from each group had experienced these crimes against themselves or their property.  A Pearson Chi-square and Analysis of Variance were carried out on the resulting dataset from the questionnaires in statistics program SPSS to analysis the results.

Of the mental health outpatients, 61% reported they had experienced ‘some kind of victimisation’ in the past 12 months, with one-third of those reporting this was a violent victimisation, a rate three and a half times higher than in the general population.  Outpatients with depression and substance misuse disorder were found to be victimised more than outpatients with severe mental illness (67%, 76% and 39% respectively).

The mental health outpatient group also experienced a higher rate of violent crime against them  (33%) compared to that experienced in the general population (9.5%), putting this group at a 3.5 times higher risk of experiencing violent victimisation compared to general population.

Property crimes were more similar across the two groups, with 36% of the outpatients experiencing property crime in this period compared to 29% of the general population. This is a 1.2 times higher risk for the mental health group than the general population group.

When interpreting such results, external factors which could have influenced these rates and experiences outside the existence of mental health issues in these subjects need to be examined.  Factors such as age, gender, ethnicity, education level and living area.  In this study, these were weighed within the general population providing the closest matches as possible and therefore they are not factors which could account for these results.

It is clear that overall those suffering with mental health issues, ranging from depression to drug use and severe psychosis experienced a considerably higher rate of criminal victimisation against them, because of their mental illness. These results are consistent with a number other studies completed within this area and supporting the notion that psychiatric patients experience more victimisation that general population.

A key finding from this study is the high level of depressive outpatients who have been a victim of violent crime with that year, 33% in total.  This suggests how vulnerable this group of outpatients are and how much of a problem victimisation against them is – at least in the Netherlands.

In an effort to explain these results, the authors have speculated using various psychological theories due to lack of research findings to be able to inform more scientifically why this might be.  They highlight the stress generation hypothesis; a theory which says that those with depressive disorders experience higher levels of negative and stressful events in their life because they are depressive and because of their own depressive behaviour.

They can be irritable, paranoid, negative, and cynical which will affect their attitude to events and people in their lives and their outward behaviour to those around them and in their life circumstances.

A domino effect where such attitudes and behaviours evoke more negativity, conflict and stress around them which in turn may result in victimisation.  This theory also suggests that while people without depressive disorders would actively avoid threatening situations, those with depressive disorders who may feel hopeless and that everything is pointless, may walk into such situations.

The cycle continues where victimisation, in turn, causes more depressive symptoms. This then may prompt a relapse in symptoms and therefore this person requires more support.  Further research is required to identify more accurately what factors may be involved in victimisation in depressive patients and how this may be overcome.

Substance Misuse and Mental Health

Turning to look at patients with substance misuse issues, this study found that overall victimisation rates were higher for this group (76%) compared to the severe mental illness group (41%), with violent victimization being almost twice the rate in substance misuse patients compared to severe mental illness group (43% to 22% respectively).

This does support results from other studies including Brekke et al (2001) who studied schizophrenia patients living within the community and Stevens et al (2007) who studied dependent drug users within Europe and the criminal victimisation in which they experience.

It was Stevens and colleagues who in their paper The Victimization of Dependent Drug Users: Findings from a European Study have provided possible explanations for why this might be.

  • Using drugs causes an increased risk of victimisation. Judgement errors and decreased ability to recognise danger when under the influence of drugs increases the risk of crimes being committed against them. Route activity theory – The people they spend their time with are in similar situations and few are people who may be able to help support them in a positive manner. This study finding that most of the drug user group suffered victimisation in public places and strangers and by people they knew could support this theory.
  • Using addictive drugs is because of victimisation that has been experienced. Flipping it around, when a person has been the victim of violence this can have a great impact on their sense of self, their self-esteem and confidence and is highly associated with depression disorders.  When in this state of mind, using drugs to relieve the anxiety and difficulty in dealing with their feelings may become an escape route.
  • Both the victimisation and the drug abuse is caused by other confounding factors such as poor mental health, living conditions, social exclusion, family violence or employment troubles. This is a more rounded theory taking into account the range of external influences and factors which are interlinked with drug abuse, including mental health.  This confirms the complexity of trying to understand the why behind a behaviour or a phenomenon such as victimisation.

A clear problem with the current study is the reliance on self-reported data from research participants.  Their honesty in the answers they provided and accuracy about their own experiences should be a factor to be aware of when interpreting these results.  Furthermore, we cannot be sure the control group participants from the community didn’t have any substance misuse or mental health problems as no measure or dataset was available to work from in that regard.

Consent was required for people to take part in the study therefore only people who wanted to take part were actively involved in the study as participants.  While this is a required and needed measure in these kind of studies it means the more severe cases of outpatient mental illness may not have been represented within this willing group sample, potentially skewing the resulting dataset.

This research highlights the need for a better understanding of mental health issues and the need for criminal victimisation to be addressed more thoroughly. In order to help those who suffer with mental ill health, a reduction in prejudice, hate crimes and abuse towards them is absolutely necessary.

Risk of Criminal Victimisation in Outpatients with Common Mental Health Disorders

ABSTRACT
Background: Crime victimisation is a serious problem in psychiatric patients. However, research has focused on patients with severe mental illness and few studies exist that address victimisation in other outpatient groups, such as patients with depression. Due to large differences in methodology of the studies that address crime victimisation, a comparison of prevalence between psychiatric diagnostic groups is hard to make. Objectives of this study were to determine and compare one-year prevalence of violent and non-violent criminal victimisation among outpatients from different diagnostic psychiatric groups and to examine prevalence differences with the general population. Method: Criminal victimisation prevalence was measured in 300 outpatients living in Amsterdam, The Netherlands. Face-to-face interviews were conducted with outpatients with depressive disorder (n = 102), substance use disorder (SUD, n = 106) and severe mental illness (SMI, n = 92) using a National Crime Victimisation Survey, and compared with a matched general population sample (n = 10865). Results: Of all outpatients, 61% reported experiencing some kind of victimisation over the past year; 33% reported violent victimisation (3.5 times more than the general population) and 36% reported property crimes (1.2 times more than the general population). Outpatients with depression (67%) and SUD (76%) were victimised more often than SMI outpatients (39%). Younger age and hostile behaviour were associated with violent victimisation, while being male and living alone were associated with non-violent victimisation. Moreover, SUD was associated with both violent and non-violent victimisation. Conclusion: Outpatients with depression, SUD, and SMI are at increased risk of victimisation compared to the general population. Furthermore, our results indicate that victimisation of violent and non-violent crimes is more common in outpatients with depression and SUD than in outpatients with SMI living independently in the community.
