Measuring Structural Stigma in Health Care

Addressing stigma in health care is crucial to ensure people with lived and living experience of mental health or substance use health concerns have access to quality care. Measuring and monitoring is a core principle of any quality improvement initiative. By measuring change, organizations can ensure that actions are effective in reducing the negative impacts of mental health and substance use (MHSU)-related structural stigma in health care.

What is structural stigma?

In health care, structural stigma encompasses the organizational and societal rules, policies, procedures, laws, and cultural norms that increase stigma and raise barriers for people seeking to access the help they need. The result is unfair treatment of people with lived and living experience (PWLLE) of mental health and/or substance use (MHSU) problems or illnesses. Such unfairness leads to inequitable access and lower quality of care for these individuals. It can also perpetuate de-prioritization, devaluation, and “othering” of mental health and substance use health, as compared with physical health, within our health-care delivery, governance, knowledge building, and training systems. 1

Research has consistently identified the health-care system as a significant contributor to stigma for PWLLE.

Structural stigma also arises in cultures of care that exude negative and disempowering policies and practices. These “stigma cultures” undermine every aspect of recovery-oriented and person-centred care and act as an important barrier to system transformation. 2

Stigma cultures are a quality-of-care issue

Stigma cultures in health-care settings are the organizational-level norms, values, assumptions, physical façades, and practices that govern day to day activities and interactions. Aspects include poor quality of care, coercive care, a punitive and patronizing atmosphere, and disempowerment to make treatment decisions. 2

Shaping cultures of care is increasingly viewed as an important means of improving safety and performance outcomes across the full spectrum of health-care settings and promoting high-quality, person-centred care. The management of cultures of care is increasingly considered to be a key aspect of health system reform, and interest in the concept of promoting more caring cultures has grown. 3

Importance of measuring structural stigma

“It doesn’t count until you count it.”
– Stephanie Knaak, Ph.D, Senior Research Consultant

It is important to measure and address structural stigma for several reasons:

It is a groundbreaking way to approach health system reform. By measuring and addressing structural stigma, organizations can become champions in the quest to provide more equitable health care for PWLLE.

Structural stigma affects not only patients and their families but also the providers who care for them. Addressing structural stigma can protect staff from experiencing moral distress. A workplace that protects workers from moral distress supports staff to do their job with a sense of integrity and in a manner consistent with their values.

Addressing structural stigma builds trust with patients and their families. Extensive research has shown that trust between patients and their providers plays an important role in producing better health outcomes. Trust in health-care institutions and health-care providers has been theorized and found to impact self-reported health, help-seeking, engagement with services, and treatment compliance. 4

Measurement Scales

An important first step to tackling structural stigma within health-care environments is to assess its scope and severity. To address this need, the Mental Health Commission of Canada (MHCC) developed the following tools to measure the scope and magnitude of stigma experienced by people with MHSU problems and illnesses:

This scale was designed to capture stigma cultures in any health-care setting (including family doctors’ offices, outpatient clinics, emergency departments, and hospitals) where people with a MHSU concern may seek care. It is a 23-item unidimensional scale.

This scale was designed to provide a cultural barometer of stigma experienced by individuals with a MHSU disorder receiving care in a MHSU service setting. It is a 20-item scale with two factors: an eight-item person-centred care factor and a 12-item coercive care factor.

The SCHCS and SSMHCS have been psychometrically tested using factor analytic procedures.

The scales are not meant to provide an objective measure of stigma. Rather, the scale scores provide a way to measure differences in experiences across different service user groups or health-care settings and/or to measure change over time. For example, higher scale or item scores (reflecting higher levels of stigma) for patient groups receiving mental health care compared with physical health care may suggest the presence of discriminatory or inequitable treatment. 2

The power of these tools is that they measure stigma from the perspective of service users themselves, thus providing a key quality assessment tool for any organization or setting interested in person-centred care.

The SCHCS or the SSMHCS can be the tool(s) that your organization needs to identify stigmatizing encounters reported by PWLLE as well to target areas in need of a change and/or to assess and monitor the impact of organizational interventions to reduce structural stigma over time.

Spotlight on early adopters

Throughout 2023 and 2024, the MHCC worked with two health-care sites to field test the measurement scales. The goal of these pilot studies was to better understand how the scale(s) work in different real-world health-care settings, identify redundancies to potentially shorten the scale(s), and facilitate opportunities for quality improvement initiatives by supporting organizations in establishing baseline measurements from which to assess the effectiveness of their interventions.

Learn about the approaches, results, and lessons learned through the two featured case studies.

Please note that both pilot studies took place at large academic hospitals; it is important to be aware of the context of a research study when considering available resources, study design, recruitment, and other factors. Health-care settings can vary substantially, and there can be differences in the way health-care research and quality improvement are approached even among provincial and territorial jurisdictions. It is important to understand that different settings will have different contexts, and methods and approaches will need to be adapted for each particular setting.

Frequently asked questions (FAQs)

Getting Started

Which scale should we select?

A: We recommend basing your selection on the type of health-care services your setting provides. SCHCS gathers more general information, while SSMHCS measures factors related to coercive care and patient-centred care, which are typically present in mental health and/or substance use health-care settings.

A: Yes. The scales have undergone psychometric testing, and through pilot site demonstration they have proven to be reliable tools to measure stigma cultures. Though data are limited, we are confident that they are effective and broadly adaptable to any health-care context.

The research for the SCHCS has been published in the peer-reviewed scholarly journal Social Psychiatry and Psychiatric Epidemiology. Read the academic paper here: Measuring aspects of stigma cultures in healthcare settings. https://link.springer.com/article/10.1007/s00127-024-02780-5#citeas

A second research paper on the SSMHCS is forthcoming.

A: Yes. You can collect whatever information will be helpful to your research. Early adopters of the scales included options for qualitative feedback for answers that were particularly negative to gather additional details and context about the participants’ experiences (i.e., if a participant answers a question with a negative versus positive response, there would be an open-field text option for them to provide additional comments).

A: We recommend using the scale in its entirety, but if there are items that will not resonate with your clientele, they can be removed. It is also possible to use a combination of the two scales. The case studies provide information on how the sites in the pilot studies approached adapting the scales into include within their own surveys.

A: There is no one ideal sample size. The ideal sample size for your project will depend on your setting, population, project aims, and available resources.

Yes. We recommend the IAP2 Framework. This has recently been adapted by the MHCC advisory councils to support meaningful engagement of PWLLE in  Engaging with People with Lived and Living Experience of Mental Illness Effectively: The MHCC’s Advisory Councils (PWLLE)

An additional resource: Guidelines for Partnering with People with Lived and Living Experience of Substance Use and Their Families and Friends.

A: This will depend on the setting. Be sure to check local policies.

Depending on the setting, ethics approval might be required to conduct this type of research. To prepare for this, a comprehensive research protocol must be developed. This should outline all the details of the study (the research question, methodology for data collection, analysis, etc.).

The World Health Organization has an excellent resource outlining the necessary elements for research protocol (available in English only).

Implementation & Recruitment

What resources (staff, time, training, etc.) are needed to implement the scale(s)?

A: There is no one-size-fits-all approach. Be sure that all staff (or volunteers) understand the goal of conducting this research. Learn more about the recruitment approaches from the two case studies and apply the lessons learned to your own context.

A: Ensure PWLLE are centred in decision-making and project planning. This way, important considerations will have been discussed on ways to ensure respect, empathy, and accessibility are central components in your data collection methodology.

A: Incentives can be powerful motivators, but they do not come without risks. However, one of the health-care sites in the case studies found that offering incentives was a successful way to facilitate data collection in the emergency department. Other settings might not need incentives to support data collection (e.g., family practice or outpatient services).

A: Depending on your protocol, you could decide to engage a proxy to complete the survey on a patient’s behalf, or you could simply not include individuals with impairments from the data collection. If you are in a setting where many patients experience cognitive impairment, consider this factor during planning.

A: It is important to consider how your clientele, particularly marginalized individuals, can access the survey. Keep in mind that clients might be experiencing precarious housing, work, or social situations. To gather a more inclusive sample, be flexible and understanding and offer alternate methods for data collection.

A: Each setting will have unique needs. A survey should be administered at least until the minimum sample size is achieved, which will vary from setting to setting. Do not attempt to collect baseline data for a long time as environmental factors will change over time, which might skew the results. Typically, a few months has been a reasonable time frame to achieve target sampling.

A: The MHCC has developed a comprehensive implementation guide that can support your efforts in producing transformative change. The structural stigma project staff is happy to answer questions to the best of their ability but cannot provide direct support for any quality improvement initiative.

Evaluation & Improvement

Will the scale(s) identify what interventions should be made?

A: No. The scale(s) are designed to assess the presence and severity of stigma cultures. Each site will need to determine appropriate interventions to suit their unique needs.

A: Changes in scale scores over time will show your organization’s progress (lower scores indicate less stigma). Measures of statistical significance will tell you if the change is real (and not due to chance), and effect-size calculations can provide a sense of the magnitude of change over time.

A: Presenting the findings to your organization’s quality improvement team, which should include patients and/or family members, is a good first step. However, a project plan should be established before data collection begins.

A: This will differ from setting to setting, but we recommend waiting at least three to six months before engaging in a second round of data collection.

A: Not every intervention is successful. Don’t become discouraged. Regroup with the project team and discuss the next steps. Forecasting possible challenges is a critical part of any project planning. It is unlikely that after appropriate interventions stigma cultures would worsen. Consider other factors that might be affecting the results.

Other tips and related resources

Use available resources to increase awareness:

Consider your organization’s readiness:

  • Any intervention to address MHSU-related structural stigma first requires an understanding of what is needed: organizational readiness to disrupt existing norms, a clear vision for change, and acceptance of the discomfort that comes from thinking about and doing things differently. Completing a readiness assessment could help your organization to better understand how implementing the SCHCS or SSMHCS fits into your site’s current work and context. The Hexagon tool 5 can assess fit and feasibility at any implementation stage.

Be realistic:

  • Transformative change takes time, and this is just the first step. You will be looking at your organization more critically and challenging existing practices and policies that may be perpetuating structural stigma. Expect pushback: remain persistent and plan for resistance.

Learn from others:

  • The “spotlight on early adopters” case studies provide valuable insight into the process of implementing the structural stigma measurement scales. Review the methods, approaches, and lessons learned to help support the development of your implementation plan.

Other measurement tools

The Mental Health Commission of Canada has been championing anti-stigma initiatives since its inception. Here are some other stigma measurement tools and resources the MHCC has developed in collaboration with Opening Minds.

The Opening Minds Stigma Scale for Health Care Providers (OMS-HC) was developed to measure stigma in health-care provider populations. To learn more, access the Opening Minds Stigma Scale for Health Care Providers (OMS-HC): Examination of psychometric properties and responsiveness. 6

The Opening Minds Provider Attitudes Toward Opioid Use Scale (OM-PATOS) was designed to help professionals who respond to or care for people who are experiencing opioid use problems or are at risk of an overdose or poisoning, such as paramedics, fire or police services workers, health-care and social-care providers, pharmacists and counsellors.
