  4. Discuss strategies to raise awareness of and mitigate or eliminate one's implicit biases.

    1 . Which of the following is a social characteristic that can trigger implicit biases?
    A) Age
    B) Disability
    C) Skin tone
    D) All of the above

    DEFINITIONS OF IMPLICIT BIAS AND OTHER TERMINOLOGIES

    Implicit biases can start as early as 3 years of age. As children age, they may begin to become more egalitarian in what they explicitly endorse, but their implicit biases may not necessarily change in accordance to these outward expressions [10]. Because implicit biases occur on the subconscious or unconscious level, particular social attributes (e.g., skin color) can quietly and insidiously affect perceptions and behaviors [11]. According to Georgetown University's National Center on Cultural Competency, social characteristics that can trigger implicit biases include [12]:

    • Age

    • Disability

    • Education

    • English language proficiency and fluency

    • Ethnicity

    • Health status

    • Disease/diagnosis (e.g., HIV/AIDS)

    • Insurance

    • Obesity

    • Race

    • Socioeconomic status

    • Sexual orientation, gender identity, or gender expression

    • Skin tone

    • Substance use

    2 . Dr. X, a physician, acknowledges that she still has a lot to learn about different racial and ethnic minority groups. She is willing to learn from her patients and assume the role of learner. Dr. X is demonstrating
    A) diversity.
    B) reflexivity.
    C) explicit bias.
    D) cultural humility.

    DEFINITIONS OF IMPLICIT BIAS AND OTHER TERMINOLOGIES

    Cultural humility refers to an attitude of humbleness, acknowledging one's limitations in the cultural knowledge of groups. Practitioners who apply cultural humility readily concede that they are not experts in others' cultures and that there are aspects of culture and social experiences that they do not know. From this perspective, patients are considered teachers of the cultural norms, beliefs, and value systems of their group, while practitioners are the learners [15]. Cultural humility is a lifelong process involving reflexivity, self-evaluation, and self-critique [16]. Experts have identified five attributes of cultural humility: openness, self-awareness, egoless, supportive interaction, and self-reflection and critique [105].

    3 . Intersectionality is a term to describe the multiple facets of identity, including race, gender, sexual orientation, religion, sex, and age.
    A) True
    B) False

    DEFINITIONS OF IMPLICIT BIAS AND OTHER TERMINOLOGIES

    Intersectionality is a term to describe the multiple facets of identity, including race, gender, sexual orientation, religion, sex, and age. These facets are not mutually exclusive, and the meanings that are ascribed to these identities are inter-related and interact to create a whole [22].

    4 . What tool is used to quantitatively measure implicit bias?
    A) IAT
    B) SOAP
    C) STOP
    D) fMRI

    MEASUREMENT OF IMPLICIT BIAS: A FOCUS ON THE IAT

    Project Implicit is a research project sponsored by Harvard University and devoted to the study and monitoring of implicit biases. It houses the Implicit Association Test (IAT), which is one of the most widely utilized standardized instruments to measure implicit biases. The IAT is based on the premise that implicit bias is an objective and discreet phenomenon that can be measured in a quantitative manner. Developed and first introduced in 1998, it is an online test that assesses implicit bias by measuring how quickly people make associations between targeted categories with a list of adjectives [33]. For example, research participants might be assessed for their implicit biases by seeing how rapidly they make evaluations among the two groups/categories career/family and male/female. Participants tend to more easily affiliate terms for which they hold implicit or explicit biases. So, unconscious biases are measured by how quickly research participants respond to stereotypical pairings (e.g., career/male and family/female). The larger the difference between the individual's performance between the two groups, the stronger the degree of bias [34; 35; 107]. Since 2006, more than 4.6 million individuals have taken the IAT, and results indicate that the general population holds implicit biases [3]. By late 2023, more than 80 million study sessions had been conducted and more than 40 million IATs completed at the Project Implicit website [107].

    6 . Which of the following is NOT a risk factor in triggering implicit biases for health professionals?
    A) Uncertainty
    B) Cognitive dissonance
    C) Time pressure to make a rapid decision
    D) Heavy workload and feeling behind schedule

    MEASUREMENT OF IMPLICIT BIAS: A FOCUS ON THE IAT

    Certain conditions or environmental risk factors are associated with an increased risk for certain implicit biases, including [44,45,106]:

    • Stressful emotional states (e.g., anger, frustration)

    • Uncertainty

    • Low-effort cognitive processing

    • Time pressure

    • Lack of feedback

    • Feeling behind with work

    • High patient caseload

    • Lack of guidance

    • Long hours

    • Patient overcrowding

    • High-crises environments

    • Mentally taxing tasks

    • High cognitive load

    • Juggling competing tasks

    7 . Rather than viewing implicit bias as an invisible force (i.e., unconscious cognitive structure), behavioral theorists consider it a normal behavior.
    A) True
    B) False

    THEORETIC EXPLANATIONS AND CONTROVERSIES

    Behavioral or functional theorists argue that implicit bias is not necessarily a latent or unconscious cognitive structure. Instead, this perspective recognizes implicit bias as a group-based behavior [52]. Behavior is biased if it is influenced by social cues indicating the social group to which someone belongs [52]. Social cues can occur rapidly and unintentionally, which ultimately leads to automatic or implicit effects on behavior. The appeal of a behavioral or functional approach to implicit bias is that it is amoral; that is, it is value- and judgment-free [52]. Rather than viewing implicit bias as an invisible force (i.e., unconscious cognitive structure), it is considered a normal behavior [53].

    8 . How might critical theory or a structural perspective be integrated into the values and ethics of interprofessional collaboration and practice?
    A) Advocate for more neurologic imaging studies to examine how implicit bias affects the brain.
    B) Analyze how communications should reflect autonomous decision-making in its role in racism.
    C) The ethical responsibility is to advocate for policies that perpetuate and reinforce implicit biases.
    D) The role of health professionals is to focus less on the unconscious and instead emphasize explicit bias as the behaviors.

    THEORETIC EXPLANATIONS AND CONTROVERSIES

    Many scholars and policymakers are concerned about the narrow theoretical views that researchers of implicit bias have taken. By focusing on unconscious cognitive structures, social cognition and neuroscientific theories miss the opportunity to also address the role of macro or systemic factors in contributing to health inequities [9,57,106]. By focusing on the neurobiology of implicit bias, for example, racism and bias is attributed to central nervous system function, releasing the individual from any control or responsibility. However, the historical legacy of prejudice and bias has roots in economic and structural issues that produce inequities [58,106]. Larger organizational, institutional, societal, and cultural forces contribute, perpetuate, and reinforce implicit and explicit biases, racism, and discrimination. Psychological and neuroscientific approaches ultimately decontextualize racism [9,57].

    In response to this conflict, a systems-based practice has been proposed [59]. This type of practice emphasizes the role of sociocultural determinants of health outcome and the fact that health inequities stem from larger systemic forces. As a result, medical and health education and training should focus on how patients' health and well-being may reflect structural vulnerabilities driven in large part by social, cultural, economic, and institutional forces. Health and mental health professionals also require social change and advocacy skills to ensure that they can effect change at the organizational and institutional levels [59].

    9 . Which of the following statements regarding health disparities is FALSE?
    A) Health disparities are linked to disadvantaged groups.
    B) Health disparities refer to differences in health status and disease that are tied to structural inequities.
    C) There are no differences in life expectancies among African Americans and White Americans.
    D) The Institute of Medicine has implicated implicit bias in the development and continuance of health disparities.

    CONSEQUENCES OF IMPLICIT BIASES

    Implicit bias has been linked to a variety of health disparities [1]. Health disparities are differences in health status or disease that systematically and adversely affect less advantaged groups [60]. These inequities are often linked to historical and current unequal distribution of resources due to poverty, structural inequities, insufficient access to health care, and/or environmental barriers and threats [61]. Healthy People 2030 defines a health disparity as [62]:

    …a particular type of health difference that is closely linked with social, economic, and/or environmental disadvantage. Health disparities adversely affect groups of people who have systematically experienced greater obstacles to health based on their racial or ethnic group; religion; socioeconomic status; gender; age; mental health; cognitive, sensory, or physical disability; sexual orientation or gender identity; geographic location; or other characteristics historically linked to discrimination or exclusion.

    As noted, in 2003, the Institute of Medicine implicated implicit bias in the development and continued health disparities in the United States [1]. Despite progress made to lessen the gaps among different groups, health disparities continue to exist. One example is racial disparities in life expectancy among Black and White individuals in the United States. Life expectancy for Black men is 4.4 years lower than White men; for Black women, it is 2.9 years lower compared with White women [63]. Hypertension, diabetes, and obesity are more prevalent in non-Hispanic Black populations compared with non-Hispanic White groups (25%, 49%, and 59% higher, respectively) [64]. In one study, African American and Latina women were more likely to experience cesarean deliveries than their White counterparts, even after controlling for medically necessary procedures [65]. This places African American and Latina women at greater risk of infection and maternal mortality.

    10 . Healthcare providers have implicit (and explicit) biases at a rate comparable to that of the general population.
    A) True
    B) False

    CONSEQUENCES OF IMPLICIT BIASES

    In an ideal situation, health professionals would be explicitly and implicitly objective and clinical decisions would be completely free of bias. However, healthcare providers have implicit (and explicit) biases at a rate comparable to that of the general population [6,69]. It is possible that these implicit biases shape healthcare professionals' behaviors, communications, and interactions, which may produce differences in help-seeking, diagnoses, and ultimately treatments and interventions [69]. For example, physicians have been shown to minimize Black patients' pain, ignore their complaints, and spend less time in examination rooms with them [111]. In a 2021 study, physicians were more likely to expect Black patients would not adhere to an HIV pre-exposure prophylaxis medication compared with White patients [112]. As a result, physicians were less likely to discuss available regimens with Black patients.

    11 . Research indicates that healthcare professionals' implicit biases are not correlated with lower scores on patient/client satisfaction.
    A) True
    B) False

    CONSEQUENCES OF IMPLICIT BIASES

    It has been hypothesized that providers' levels of bias affect the ratings of patient-centered care [34]. Patient-centered care has been defined as patients' positive ratings in the areas of perception of provider concern, provider answering patients' questions, provider integrity, and provider knowledge of the patient. Using data from 134 health providers who completed the IAT, a total of 2,908 diverse racial and ethnic minority patients participated in a telephone survey. Researchers found that for providers who scored high on levels of implicit bias, African American patients' ratings for all dimensions of patient-centered care were low compared with their White patient counterparts. Latinx patient ratings were low regardless of level of implicit bias.

    A 2013 study recorded clinical interactions between 112 low-income African American patients and their 14 non-African American physicians for approximately two years [71]. Providers' implicit biases were also assessed using the IAT. In general, the physicians talked more than the patients; however, physicians with higher implicit bias scores also had a higher ratio of physician-to-patient talk time. Patients with higher levels of perceived discrimination had a lower ratio of physician-to-patient talk time (i.e., spoke more than those with lower reported perceived discrimination). A lower ratio of physician-patient talk time correlated to decreased likelihood of adherence.

    Another study assessed 40 primary care physicians and 269 patients [72]. The IAT was administered to both groups, and their interactions were recorded and observed for verbal dominance (defined as the time of physician participation relative to patient participation). When physicians scored higher on measures of implicit bias, there was 9% more verbal dominance on the part of the physicians in the visits with Black patients and 11% greater in interactions with White patients. Physicians with higher implicit bias scores and lower verbal dominance also received lower scores on patient ratings on interpersonal care, particularly from Black patients [72].

    12 . An implicit bias training is offered at a hospital, and a total of 50 health professionals attend. During the breakout session, training participants are assigned to discussion groups. One nurse agrees that implicit bias is prevalent, but she is quite sure she does not hold any implicit biases. Which developmental stage might this nurse be in?
    A) Defense
    B) Minimization
    C) Structural competence
    D) Counter-stereotype acceptance

    DEVELOPMENTAL MODEL TO RECOGNIZING AND REDUCING IMPLICIT BIAS

    There are no easy answers to raising awareness and reducing health providers' implicit bias. Each provider may be in a different developmental stage in terms of awareness, understanding, acceptance, and application of implicit bias to their practice. A developmental model for intercultural sensitivity training has been established to help identify where individuals may be in this developmental journey [74,75]. It is important to recognize that the process of becoming more self-aware is fluid; reaching one stage does not necessarily mean that it is "conquered" or that there will not be additional work to do in that stage. As a dynamic process, it is possible to move back and forth as stress and uncertainty triggers implicit biases [74]. This developmental model includes six stages:

    • Denial: In this stage, the individual has no awareness of the existence of cultural differences between oneself and members of other cultural groups and subgroups. Individuals in this stage have no awareness of implicit bias and cannot distinguish between explicit and implicit biases.

    • Defense: In this stage, the person may accept that implicit biases exist but does not acknowledge that implicit biases exist within themselves.

    • Minimization: An individual in this stage acknowledges that implicit biases may exist in their colleagues and possibly themselves. However, he or she is uncertain of their consequences and adverse effects. Furthermore, the person believes he or she is able to treat patients in an objective manner.

    • Acceptance: In the acceptance stage, the individual recognizes and acknowledges the role of implicit biases and how implicit biases influence interactions with patients.

    • Adaptation: Those in the adaptation stage self-reflect and acknowledge that they have unrecognized implicit biases. Not only is there an acknowledgement of the existence of implicit bias, these people begin to actively work to reduce the potential impact of implicit biases on interactions with patients.

    • Integration: At this stage, the health professional works to incorporate change in their day-to-day practice in order to mitigate the effects of their implicit biases on various levels—from the patient level to the organization level.

    13 . If psychological safety is threatened, what might be a potential outcome in implicit bias training?
    A) Recriminations
    B) Self-confessions of guilt
    C) Health disparities increase
    D) Learning may be compromised

    CREATING A SAFE ENVIRONMENT

    Creating and fostering a sense of psychological safety in the learning environment is crucial. Psychological safety results when individuals feel that their opinions, views, thoughts, and contributions are valued despite tension, conflict, and discomfort. This allows the individual to feel that their identity is intact [76]. When psychological safety is threatened, individuals' energies are primarily expended on coping rather than learning [76]. As such, interventions should not seek to confront individuals or make them feel guilty and/or responsible [77].

    14 . When implicit bias interventions or assessments are planned, facilitators should be open, approachable, non-threatening, and knowledgeable.
    A) True
    B) False

    CREATING A SAFE ENVIRONMENT

    When implicit bias interventions or assessments are planned, facilitators should be open, approachable, non-threatening, and knowledgeable; this will help create a safe and inclusive learning environment [77]. The principles of respect, integrity, and confidentiality should be communicated [77]. Facilitators who demonstrate attunement, authenticity, and power-sharing foster positive and productive dialogues about subjects such as race and identity [76]. Attunement is the capacity of an individual to tacitly comprehend the lived experiences of others, using their perspectives to provide an alternative viewpoint for others. Attunement does not involve requiring others to talk about their experiences if they are not emotionally ready [76]. Authenticity involves being honest and transparent with one's own position in a racialized social structure and sharing one's own experiences, feelings, and views. Being authentic also means being vulnerable [76]. Finally, power-sharing entails redistributing power in the learning environment. The education environment is typically hierarchical, with an expert holding more power than students or participants. Furthermore, other students may hold more power by virtue of being more comfortable speaking/interacting [76]. Ultimately, promoting a safe space lays a foundation for safely and effectively implementing implicit bias awareness and reduction interventions.

    15 . Some have suggested using SOAP (subjective, objective, assessment, and plan) notes to assist practitioners in identifying implicit biases in day-to-day interactions with patients.
    A) True
    B) False

    STRATEGIES TO PROMOTE AWARENESS OF IMPLICIT BIAS

    Another way of facilitating awareness of providers' implicit bias is to ask self-reflective questions about each interaction with patients. Some have suggested using SOAP (subjective, objective, assessment, and plan) notes to assist practitioners in identifying implicit biases in day-to-day interactions with patients [80]. Integrating the following questions into charts and notes can stimulate reflection about implicit bias globally and for each specific patient interaction:

    • Did I think about any socioeconomic and/or environmental factors that may contribute to the health and access of this patient?

    • How was my communication and interaction with this patient? Did it change from my customary pattern?

    • How could my implicit biases influence care for this patient?

    16 . Increasing awareness of biased thoughts and responses is an example of a change-based intervention.
    A) True
    B) False

    INTERVENTIONS TO REDUCE IMPLICIT BIASES

    Interventions or strategies designed to reduce implicit bias may be further categorized as change-based or control-based [58]. Change-based interventions focus on reducing or changing cognitive associations underlying implicit biases. These interventions might include challenging stereotypes. Conversely, control-based interventions involve reducing the effects of the implicit bias on the individual's behaviors [58]. These strategies include increasing awareness of biased thoughts and responses. The two types of interventions are not mutually exclusive and may be used synergistically. In a similar vein, interventions targeted on implicit biases may be categorized as either those that "de-bias" or neutralize or that raise awareness [116].

    17 . As part of an implicit bias training, participants watch a film about an African American man's experiences navigating the health system and are asked to enter the protagonist's lived reality. What type of intervention is this?
    A) Priming
    B) Attunement
    C) Control strategies
    D) Perspective taking

    INTERVENTIONS TO REDUCE IMPLICIT BIASES

    Perspective taking is a strategy of taking on a first-person perspective of a person in order to control one's automatic response toward individuals with certain social characteristics that might trigger implicit biases [82; 117]. The goal is to increase psychological closeness and empathy, anticipate others' feelings and reactions, and facilitate connection with members of the group [4; 117]. Engaging with media that presents a perspective (e.g., watching documentaries, reading an autobiography) can help promote better understanding of the specific group's lives, experiences, and viewpoints. In one study, participants who adopted the first-person perspectives of African Americans had more positive automatic evaluations of the targeted group [83]. However, one of the critiques to perspective taking is that instead of highlighting similarities, differences can be emphasized and could result in reinforced stereotypes [117].

    18 . Mr. A, a social worker, attempts to record personal information about his patients and not simply social characteristics. For example, he writes, "Patient is an elderly Hispanic woman, age 79 years. She lives with her daughter and is an avid pianist." What is this an example of?
    A) STOP
    B) Priming
    C) Power-sharing
    D) Individuation

    INTERVENTIONS TO REDUCE IMPLICIT BIASES

    Individuation is an implicit bias reduction intervention that involves obtaining specific information about the individual and relying on personal characteristics instead of stereotypes of the group to which he or she belongs [4,82]. The key is to concentrate on the person's specific and unique experiences, achievements, personality traits, qualifications, and other personal attributes rather than focusing on gender, race, ethnicity, age, ability, and other social attributes, all of which can activate implicit biases [118]. Teaching individuals to pause and take time to ask questions instead of relying on assumptions is vital [118]. When providers lack relevant information, they are more likely to fill in data with stereotypes, in some cases unconsciously. Time constraints and job stress increase the likelihood of this occurring [69].

    19 . Counter-stereotypical imaging approaches involve presenting an image, idea, or construct that is counter to the oversimplified stereotypes typically held regarding members of a specific group.
    A) True
    B) False

    INTERVENTIONS TO REDUCE IMPLICIT BIASES

    Counter-stereotypical imaging approaches involve presenting an image, idea, or construct that is counter to the oversimplified stereotypes typically held regarding members of a specific group [120]. In one study, participants were asked to imagine either a strong woman (the experimental condition) or a gender-neutral event (the control condition) [92]. Researchers found that participants in the experimental condition exhibited lower levels of implicit gender bias. Similarly, exposure to female leaders was found to reduce implicit gender bias [93]. Whether via increased contact with stigmatized groups to contradict prevailing stereotypes or simply exposure to counter-stereotypical imaging, it is possible to unlearn associations underlying various implicit biases. If the social environment is important in priming positive evaluations, having more positive visual images of members in stigmatized groups can help reduce implicit biases [94]. Inviting speakers whose demographic background is different from staff or other invited presenters is also a good practice [120]. Some have suggested that even just hanging photos and having computer screensavers reflecting positive images of various social groups could help to reduce negative associations [94].

    20 . All of the following are concerns with research conducted to examine the effectiveness of implicit bias reduction interventions, EXCEPT:
    A) The studies conducted to examine implicit bias reduction interventions utilize cross-sectional and not longitudinal designs.
    B) The studies conducted to examine implicit bias reduction interventions may not be generalizable to the general population.
    C) The studies conducted to examine implicit bias reduction interventions have measured long-term but not immediate outcomes.
    D) Study samples have tended to include psychology students and it is not clear whether findings can be applied to other populations.

    INTERVENTIONS TO REDUCE IMPLICIT BIASES

    In general, the sample sizes were small. It is also unclear how generalizable the findings are, given many of the research participants were college psychology students. The 30 studies included in the meta-analysis were cross-sectional (not longitudinal) and only measured short-term outcomes, and there is some concern about "one shot" interventions, given the fact that implicit biases are deeply embedded. Would simply acknowledging the existence of implicit biases be sufficient to eliminate them [95,96]? Or would such a confession act as an illusion to having self-actualized and moved beyond the bias [95]? Others have questioned the effectiveness interventions to reduce implicit biases on a long-term basis and suggest that institutional strategies to identify and address biases may be more effective [121]. One example is the University of Washington's School of Medicine's online reporting mechanism, which allows individuals who are either third-party observers or who are targets to report issues. When necessary, follow-up to reported incidents are conducted by human resources.
