Summary

Prevention of mental disorders can be effective, but is rarely implemented in routine settings. Here we propose a matrix to show how different aspects of stigma, discrimination and lack of knowledge can hinder different types of prevention, including early intervention. Programmes to reduce stigma's impact and so to facilitate prevention are needed.

The potential benefits from preventing mental illnesses are considerable, both in terms of illness burden for people with mental illness, their families and carers as well as in socioeconomic terms. Evidence so far suggests that prevention can reduce the incidence of mental disorders and can be cost-effective. Reference Mihalopoulos, Vos, Pirkis and Carter1 However, available prevention strategies are rarely implemented in routine public health or mental health service programmes. Here we put forward the hypothesis that the stigma and discrimination associated with mental illness may act as barriers to preventing mental illnesses. We propose a 4×3 matrix to show how three types of stigma and lack of knowledge can hinder three types of prevention (see Appendix).

Forms of prevention and stigma

Prevention in mental health can be categorised in two ways. Reference Compton2 The traditional classification distinguishes prevention according to the illness stage: primary prevention addresses risk factors in order to reduce the number of new cases or the incidence; secondary prevention occurs during the early stages of the disease process; and the domain of tertiary prevention is relapse prevention and rehabilitation after illness onset. The Institute of Medicine’s 3 newer classification arranges prevention efforts according to the target group: universal prevention in the general population, selective prevention for persons at risk (for example children of parents with mental illness), and indicated prevention for people with early signs and symptoms who do not meet diagnostic criteria, but who are at high risk to be in the early subthreshold stages of a developing mental illness. In the Appendix we collapse selective, indicated and secondary prevention into one category, referring to prevention for individuals at elevated risk to develop a mental illness as compared with the general population.

Stigma associated with mental illness is an overarching term that comprises three main components: negative stereotypes (such as ‘people with mental illness are responsible for their condition’); prejudice that refers to agreeing with these stereotypes and negative emotional reactions (‘That’s right, they are to blame and I am angry at them’); and finally discrimination as the behavioural consequence (‘I oppose funding for mental health prevention’). Lack of knowledge or poor mental health literacy is a distinct, but related concept insofar as negative stereotypes about people with mental illness represent factually wrong or one-sided assumptions that are commonly held in society and are a prerequisite for stigma. However, mental health literacy is more than the absence of erroneous stereotypes and includes the recognition of a developing disorder as well as knowledge about prevention and effective interventions. Reference Jorm4 We therefore refer to poor knowledge as a barrier to prevention in its own right in addition to stigma.

Stigma can express itself in three ways: (a) public stigma, when members of the general public endorse prejudice and discrimination against people with mental illness; (b) self-stigma when people with mental illness agree with and internalise negative stereotypes, leading to low self-esteem, shame, demoralisation and giving up life goals; Reference Corrigan, Larson and Rüsch5 and (c) structural discrimination or rules and regulations in society that intentionally or unintentionally disadvantage people with mental illness, for example by the amount of resources dedicated to mental health services.

Stigma and lack of knowledge as barriers to prevention

In the Appendix, we outline how three forms of stigma as well as poor mental health literacy can impair three types of prevention. We postulate the following two main effects. First, prevention may simply not happen because it is not implemented (because of structural discrimination, public stigma or lack of knowledge) or because people do not participate in it (avoidance as a result of fear of public stigma, self-stigma or lack of knowledge). Second, even if implemented, prevention may not succeed (because of direct negative effects of public, self or structural stigma on well-being of the target group). More specifically and regarding different types of prevention, primary or universal prevention will likely be more difficult to implement among members of the public who have poor knowledge about mental health, who distance themselves from people with mental illness, who hold pessimistic views about the benefits of prevention, and who are opposed to channelling resources towards mental health. Reference Jorm4,Reference Schomerus, Matschinger and Angermeyer6 With respect to tertiary prevention, on the other hand, there is ample qualitative and quantitative evidence that stigma is a barrier to mental health service use and relapse prevention. Reference Clement, Schauman, Graham, Maggioni, Evans-Lacko and Bezborodovs7 Conceptually and practically, secondary prevention has an intermediate status because its target population, people at higher risk to develop a mental disorder, may or may not self-label and refer to themselves as having a mental health problem. Depending on their self-concept and the type and timing of the intervention, public stigma and self-stigma/shame may hinder them to participate or may, for example because of stigma as a stressor, worsen clinical outcomes.

Applying the stigma-prevention matrix to future research

The matrix may serve several purposes. First of all, the literatures on prevention and on stigma, both rich in their own right, could be better connected to allow more cross-fertilisation. For example regarding the potential role of stigma for indicated prevention among young people at risk for psychosis, recent findings suggest that the more young people at risk perceive stigma as a stressor that exceeds their coping resources, the more negative their attitudes are towards seeking professional help. Reference Rüsch, Heekeren, Theodoridou, Dvorsky, Müller and Paust8 Another example is that beyond attitude surveys we do not know what members of the public actually do to prevent mental disorders, let alone how their attitudes and knowledge are related to their real-world behaviours. Reference Jorm4 A final example is that public surveys suggest that although members of the public recognise the burden and disability caused by mental disorders they remain hesitant to allocate resources to mental health prevention and services, but the role of stigma for public preferences is still poorly understood. Reference Schomerus, Matschinger and Angermeyer6,Reference Corrigan and Watson9

Second, our matrix might be used to generate and test hypotheses on how interventions meant to address stigma or lack of mental health-related knowledge affect prevention, and vice versa how prevention efforts influence stigma variables. For instance, interventions reducing the shame and self-stigma associated with at-risk state or early psychosis could increase the success of prevention because, by addressing shame and self-stigma, such programmes target factors that undermine self-efficacy and hope. On the other hand, selective or indicated prevention may well lead to intended or unintended (self-)labelling as ‘mentally ill’. This label may be helpful, facilitating help-seeking, or harmful, leading to stigma and self-stigma. Reference Rüsch, Heekeren, Theodoridou, Dvorsky, Müller and Paust8,Reference Rüsch, Corrigan, Heekeren, Theodoridou, Dvorsky and Metzler10 Another example refers to the allocation of resources to the prevention of mental disorders as an example of unintended structural discrimination. Studies are needed to examine whether interventions targeting policy makers or the general population will achieve a fairer resource allocation and improve the implementation and quality of prevention programmes.

Traditional classification of prevention according to illness phase Primary prevention Secondary prevention Tertiary prevention
New classification of prevention according to target population Examples Universal prevention Selective or indicated prevention
- Media campaigns against alcohol misuse or violence in the family - Group programmes for children of parents with mental illness (selective prevention) - Relapse prevention
- Low threshold services for people with mental illness currently not in treatment
- Early intervention for young people at risk for psychosis (indicated prevention)
Poor knowledge - Poor knowledge about risk and protective factors - Poor knowledge about early intervention - Poor knowledge about available treatments and relapse prevention
- Poor recognition of early signs and symptoms
Public stigma - Unwillingness to participate in or implement prevention due to prejudice against people with mental illness - Avoidance of early recognition/intervention due to fear of public stigma - Avoidance of service use due to fear of public stigma
- Discrimination as a barrier to recovery (for example work, relationships, housing)
- Pessimism about success of early intervention
- Pessimism about success of prevention
- Labelling as unintended consequence of prevention, leading to stigma-related stress
Self-stigma - Avoidance of early recognition/intervention because of self-stigma/shame - Avoidance of service use because of self-stigma/shame
- Demoralisation, ‘why try’, and social isolation as consequences of self-stigma
- Self-labelling as unintended consequence of prevention, leading to shame and demoralisation
Structural discrimination - Allocation of fewer resources to prevention in mental health - Underresourced early intervention services - Under-resourced mental health services lead to poorer quality and quantity of available mental health services
- Negative media portrayals of people with mental illness that discourage prevention

Once we better understand the interaction of knowledge, stigma and prevention, we will be able to design and implement interventions for both sides of the coin: prevention programmes in public health and clinical settings as well as addressing the social consequences of mental illness. This two-pronged approach, taking into account the illness and the stigma associated with it, is needed to reduce the burden of mental illness on individuals and society.
