From inclusion to control: Structural racism in medical organization governance
This study examines organizational racial power dynamics through a case study of the interactions between a Diversity, Equity, and Inclusion (DEI) Committee and the Board of Directors at an organization specializing in health care practitioner training. We explore how power—defined as control over resources by certain individuals while others lack such control—can be utilized constructively or destructively. Understanding the hoarding of power to…
Antiracist mental healthcare training and development of multicultural awareness, knowledge and skills among school mental health providers in Canada
In Canada, mental health disparities persist among racialized populations, including Black, Indigenous and other people of color. A major barrier to equitable care is the lack of adequate training of mental health professionals on racial issues. To address this unmet need, Cénat and colleagues introduced the Providing Antiracist Mental Health Care online training course. This contains five modules addressing: (a) awareness of racial issues, (b) a…

Organizational culture, policies, and procedures can prevent or promote sexual violence. Lensed through a case study of one woman police officer and her abuse, this paper examines the organizational issues surrounding sexual harassment and abuse in law enforcement and the impact on officers' psychological well-being. We review issues surrounding workplace discrimination that pose hurdles to reporting. We present concrete guidelines for promoting …
Navigating the “Psychedelic Renaissance”: From Research to Reality
MDMA-Assisted Therapy for Posttraumatic Stress Disorder: A Mixed-Methods Case Study of a Participant of Color From an Open-Label Trial
MDMA (±3,4-methylenedioxymethamphetamine)-assisted therapy (MDMA-AT) was shown in previous clinical trials to have promising efficacy and safety for alleviating treatment-resistant posttraumatic stress disorder (PTSD). However, due to low ethnoracial diversity, the question remains as to whether ethnoracial minority participants would benefit similarly. Thus, a mixed-methods case study was conducted on a participant of color from an open-label tr…
Exploring effects and experiences of ketamine in group couples therapy
BackgroundThis study contributes to the understanding of the efficacy, safety, and experience of ketamine-assisted therapy. The paper documents how individuals describe the effects of a protocolized and personalized use of ketamine ('the relational dose') in the context of group couples therapy based on Imago Relationship Therapy (IRT). Little is known about simultaneously administering ketamine to both members of a couple in this context, and no…
Ketamine and epigenetic processes in depression, intersection between serotonergic and glutamatergic pathways
BackgroundHypotheses surrounding the etiology of depressive disorders encompass a wide range of biological changes that can occur in a depressed individual, from gene variations to epigenetic modifications and not only serotonergic mechanisms. Once again, the therapy response of the patient to antidepressants is connected to modifications in the epigenetic regulation of genes within the serotonergic system. The persistence of depressive symptoms …
Experiences of psychedelic drug use among people with psychotic symptoms and disorders: Personal growth and mystical experiences
Individuals with a history of psychotic experiences and disorders such as schizophrenia, and mood disorders with psychotic features tend to be excluded from psychedelic-assisted therapy research and treatment programs, despite minimal research demonstrating heightened risk of adverse effects for this group. Participants (n = 100) were asked to complete an online, retrospective survey that asked about psychotic experiences and/or diagnoses and one…
The mushroom was more alive and vibrant: Patient reports of synthetic versus organic forms of psilocybin
Interest in psychedelic research in the West is surging, however, clinical trials have almost exclusively studied synthetic compounds such as MDMA, ketamine, DMT, LSD, ibogaine, and psilocybin. To date, few clinical trials have utilized whole mushroom/plant material like Psilocybe mushrooms, Iboga, or Ayahuasca. Individuals participating in the Roots To Thrive Psilocybin-Assisted Therapy for End of Life Distress program were administered syntheti…

Healing Words: Effects of Psychoeducation on Likelihood to Seek and Refer Psychedelic-Assisted Psychotherapy Among Bipoc Individuals
Psychedelic-assisted psychotherapy (PAP) is gaining renewed interest as a treatment for various mental disorders. However, there has been limited Black, Indigenous, and People of Color (BIPOC) representation in PAP clinical trials, signaling the need for culturally consonant communication about the efficacy and safety of PAP. We randomly assigned 321 BIPOC and 301 non-Hispanic White participants to four different modes of psychoeducation (didacti…
Building Psychedelic Studies as an Interdisciplinary Academic Field: Its Urgency and Its Challenges
The field of psychedelic studies is expanding at a rapid pace and the need for academic institutions to engage more directly with this emergent field is growing. There have been some initial moves within the academy to begin tackling this evolving landscape, but these efforts have been relatively siloed along traditional disciplinary lines. Academic inquiry helps shape our collective engagement with – and understanding of – the world around us. A…
Research abuses against people of colour and other vulnerable groups in early psychedelic research
There is a growing resurgence in the study of psychedelic medicines for the treatment of mental health and substance use disorders. However, certain early investigations are marred by questionable research methods, abuses against research participants, and covert Central Intelligence Agency financial involvement. The purpose of this study was to understand how and to what extent people of colour and other vulnerable populations, specifically, ind…
Lifetime Trauma Exposure and Posttraumatic Stress Disorder Among African Americans and Black Caribbeans by Sex and Ethnicity
Future PTSD-related research should aim to characterize the heterogenous experiences of potentially traumatic events within different Black communities. Clinicians working with Black clients should strive to understand the limitations within their tools/interventions in meeting the needs of diverse groups
Effects of Psychedelic Use on Racial Trauma Symptoms and Ethnic Identity among Asians in North America
There is a need to understand ways in which Asians in North America attempt to heal from racial trauma, given their well-documented high risk of exposure and associated adverse mental health outcomes. We conducted a secondary analysis of Asians from a survey of people of color in North America who have consumed psychedelics in response to racial discrimination. Ninety-two Asian participants ( M age = 30.25, SD = 6.83) completed online questions a…
Racial justice allyship requires civil courage: A behavioral prescription for moral growth and change
In racialized societies, race divides people, prioritizes some groups over others, and directly impacts opportunities and outcomes in life. These missed opportunities and altered outcomes can be rectified only through the deliberate dismantling of explicit, implicit, and systemic patterns of injustice. Racial problems cannot be corrected merely by the good wishes of individuals-purposeful actions and interventions are required. To create equitabl…
After Pierce and Sue: A Revised Racial Microaggressions Taxonomy
Harvard psychiatrist Chester Pierce’s conception of “subtle and stunning” daily racial offenses, or microaggressions, remains salient even 50 years after it was introduced. Microaggressions were defined further by Sue and colleagues in 2007, and this construct has found growing utility as the deleterious effects of microaggressions on the health of people of color continues to mount. Many studies seek to frame microaggressions in terms of a taxon…
Racial and Language Microaggressions in the School Ecology
The growth trajectory of ethnically and linguistically diverse individuals in the United States, particularly for youth, compels the education system to have urgent awareness of how diverse aspects of culture (e.g., Spanish-speaking, Black Latina student) are implicated in outcomes in American school systems. Students spend a significant amount of time in the school ecology, and this experience plays an important role in their well-being. Diverse…

In recent years, the study of psychedelic science has resurfaced as scientists and therapists are again exploring its potential to treat an array of psychiatric conditions, such as depression, post-traumatic stress disorder, and addiction. The scientific progress and clinical promise of this movement owes much of its success to the history of indigenous healing practices; yet the work of indigenous people, ethnic and racial minorities, women, and…
A qualitative study of microaggressions against African Americans on predominantly White campuses
Diversity, equity, and access in psychedelic medicine
Although it is exciting to witness the culmination of decades of drug policy advocacy and clinical research, the psychedelic science movement struggles with many of the same social issues that plague healthcare in general. The healing properties of plant medicines and their derivatives were originally brought to Western consciousness by indigenous cultures from all over the world. These practices are now being adapted to Western models of healthc…
The Need for Shared Nomenclature on Racism and Related Terminology in Psychology
With the increased desire to engage in antiracist clinical research, there is a need for shared nomenclature on racism and related constructs to help move the science forward. This article breaks down the factors that contributed to the development and maintenance of racism (including racial microaggressions), provides examples of the many forms of racism, and describes the impact of racism for all. Specifically, in the United States, racism is b…

Preparing for racial microaggressions: The role of cognition and emotion in the proactive coping process of African American college students
Culturally informed research design issues in a study for MDMA-assisted psychotherapy for posttraumatic stress disorder
Recent research suggests that psychedelic drugs can be powerful agents of change when utilized in conjunction with psychotherapy. Methylenedioxymethamphetamine (MDMA)-assisted psychotherapy has been studied as a means of helping people overcome posttraumatic stress disorder, believed to work by reducing fear of traumatic memories and increasing feelings of trust and compassion toward others, without inhibiting access to difficult emotions. Howeve…
Discrimination and symptoms of obsessive–compulsive disorder among African Americans
This study examined symptoms of obsessive-compulsive disorder (OCD) in a nationally representative sample of African American adults (n = 3,570) and correlations between OCD symptom dimensions and experiences of discrimination. Two categories of discrimination were examined, everyday racial discrimination and everyday nonracial discrimination (e.g., because of gender, age, and weight), to determine if racial discrimination had a unique impact on …
Depression Is Real: Developing a Health Communication Campaign in an Urban African American Community
Background: Depression is the leading cause of disability in the United States. African Americans are disproportionately affected owing to systemic and sociocultural factors. Stigma, denial, and inadequate knowledge on depression are significant barriers to mental help seeking. Addressing mental health literacy can improve mental health knowledge, management, and outcomes. West Louisville, a predominantly African American community, is of particu…
Racial/ethnic differences in prevalence of hallucinogen use by age cohort: Findings from the 2018 National Survey on Drug Use and Health
BackgroundFew studies have assessed the epidemiology of hallucinogenic substance use among racial and ethnic groups of varying age cohorts. Use of psychedelic substances may differ among people of color (POC), due to factors such as stigma and discriminatory drug enforcement practices against POC. The lack of inclusion of POC in psychedelic research further underscores the importance of identifying differences in use among racial/ethnic groups an…

Obsessive–compulsive disorder in African American children and adolescents: Risks, resiliency, and barriers to treatment
Obsessive-compulsive disorder (OCD) is a serious condition that remains understudied in ethnoracial minority populations. The presence of OCD and the individual, familial, and cultural factors that influence this condition can interfere with healthy development and cause lifelong disability. To date, there has not been a single published research article focused on OCD in African American youth. Ethnic and racial minorities with OCD are underrepr…
Psychiatric Comorbidity and Hoarding Symptoms in African Americans With Obsessive-Compulsive Disorder
This study investigated comorbidity and hoarding symptoms in a sample of African American adults with obsessive-compulsive disorder ( N = 75). For lifetime disorders, 87.9% of participants had at least one other comorbid condition. The most prevalent comorbidities were mood disorders (67.1%), anxiety disorders (51.4%), and substance abuse disorders (38.0%). There was low comorbidity with eating disorders, as only 4.1% had binge-eating disorder an…
Inclusion of people of color in psychedelic-assisted psychotherapy: A review of the literature
BACKGROUND: Despite renewed interest in studying the safety and efficacy of psychedelic-assisted psychotherapy for the treatment of psychological disorders, the enrollment of racially diverse participants and the unique presentation of psychopathology in this population has not been a focus of this potentially ground-breaking area of research. In 1993, the United States National Institutes of Health issued a mandate that funded research must incl…
Assessing racial trauma within a DSM–5 framework: The UConn Racial/Ethnic Stress & Trauma Survey.

Microaggressions: Clarification, Evidence, and Impact
In a 2017 article in Perspectives on Psychological Science, Scott Lilienfeld critiqued the conceptual basis for microaggressions as well as the scientific rigor of scholarship on the topic. The current article provides a response that systematically analyzes the arguments and representations made in Lilienfeld’s critique with regard to the concept of microaggressions and the state of the related research. I show that, in contrast to the claim tha…
