Group Ketamine Therapy for Identity-Based Trauma

Ketamine-assisted psychotherapy (KAP) research has overwhelmingly focused on individual treatment. But for people whose suffering is rooted in social identity — discrimination, marginalization, internalized stigma — healing in isolation may miss something essential. A 2026 pilot study published in Frontiers in Psychiatry by Sevelius and colleagues tested group KAP for transgender and gender-expansive adults experiencing identity-based trauma. The results were striking.

The "Kindred" Program

The study, named "Kindred," enrolled eight transgender and gender-expansive adults who reported significant identity-based trauma — the cumulative psychological impact of discrimination, harassment, rejection, and violence tied to gender identity. These participants experienced elevated rates of depression, anxiety, shame, and suicidality, consistent with well-documented mental health disparities affecting transgender populations.

The treatment protocol spanned nine weeks and alternated between group KAP sessions and group cognitive processing therapy (CPT). CPT is an evidence-based trauma therapy that helps patients examine and reframe the unhelpful beliefs that develop in response to traumatic experiences. By combining KAP with CPT in a group format, the researchers created a treatment that addressed trauma at both neurobiological and psychological levels within a community context.

Ketamine was administered during designated sessions under medical supervision, with the group format allowing participants to share the experience alongside peers who understood their struggles firsthand.

Results: Across-the-Board Improvements

The findings exceeded what the researchers anticipated for a pilot study of this size:

• 100% retention: All eight participants completed the full nine-week protocol. In clinical trials involving marginalized populations — who often face barriers to sustained engagement with healthcare systems — this is exceptional.
• Significant reduction in depression and anxiety: Participants reported meaningful improvements in depressive and anxiety symptoms as measured by validated clinical scales.
• Decreased cognitive fusion: Cognitive fusion — the tendency to become entangled with and controlled by negative thoughts — decreased significantly. This is important because high cognitive fusion is associated with rigid, shame-driven thought patterns common in identity-based trauma.
• Reduced shame and internalized transphobia: Participants reported lower levels of shame and decreased internalized transphobia, suggesting that the treatment addressed not just symptoms but the underlying psychological mechanisms driving distress.
• Decreased suicidality: Given the elevated suicide risk in transgender populations, any intervention that meaningfully reduces suicidal ideation deserves close attention.

Why Group Format Matters

The decision to use a group format was not incidental — it was central to the therapeutic hypothesis. Identity-based trauma is, by definition, social in origin. It arises from how the world treats people because of who they are. Healing from this kind of trauma in a group of people with shared experiences offers something that individual therapy cannot: peer validation, belonging, and the lived experience of being seen and accepted.

Group KAP creates a shared altered state of consciousness in which participants can access emotional material together, witness each other's vulnerability, and experience connection at a time when the brain is primed for new learning and emotional processing. The neuroplasticity window that ketamine opens is not just available for individual insight — it can be leveraged for relational healing.

Participants in the Kindred study reported that the group component was among the most meaningful aspects of the treatment. Feeling understood by peers, rather than having to explain their experiences to someone outside their community, reduced the therapeutic burden and allowed deeper engagement with the trauma processing work.

The Broader Significance

This study matters for several reasons beyond its specific population.

First, it demonstrates the feasibility and safety of group KAP. While group psychedelic-assisted therapy has been explored in other contexts, rigorous data on group KAP has been limited. The 100% retention rate and absence of serious adverse events are encouraging signals for future research.

Second, it opens the door to applying group KAP for other forms of identity-based trauma. Racial trauma, trauma related to sexual orientation, disability-related stigma, and other forms of marginalization-based suffering could potentially benefit from similar models that combine ketamine's neuroplastic effects with group-based trauma processing.

Third, it highlights the importance of culturally responsive approaches in psychedelic medicine. The Kindred program was designed by and for the community it served, with attention to the specific psychological dynamics of gender identity-based trauma. This stands in contrast to one-size-fits-all approaches that may not address the unique needs of marginalized patients.

Isha Health's Commitment to Inclusive Care

At Isha Health, we believe that effective ketamine therapy must be accessible and affirming for all patients. Our ketamine therapist directory includes clinicians who specialize in LGBTQ-affirmative care, and patients can filter for providers with relevant experience and training.

While Isha Health's current model focuses on individual at-home treatment rather than group therapy, the principles underlying the Kindred study resonate with our approach: ketamine works best when it is embedded in a therapeutic relationship that understands and respects the patient's full identity and experience.

For patients exploring ketamine therapy, finding a provider who understands their background is not a luxury — it is a clinical necessity. Browse our therapist directory to find a clinician who is right for you, or learn more about Isha Health's online ketamine therapy program.
