Global mental health data gaps: How colonial metrics and cultural bias distort burden estimates worldwide
Original framing: “[Correspondence] Cultural calibration is needed in global mental disorder burden estimates – Authors’ reply” — The Lancet
The GBD study silences marginalized voices like those of the *Black Women’s Health Study*, which found that Black women’s mental health struggles are systematically attributed to 'cultural stigma' rather than racialized medical gaslighting, or the *Dalit* communities in India, where caste-based trauma is pathologized as 'neurasthenia.' The *Indigenous Psychologists Association* has repeatedly criticized GBD’s exclusion of *Two-Eyed Seeing* (Mi’kmaq) models, which integrate Western and Indigenous knowledge, yet these critiques are absent from the study’s 'cultural calibration' discussions. Even within Western contexts, *LGBTQ+* communities highlight how GBD’s metrics fail to account for intersectional trauma, such as the 40% higher suicide rates among trans women of color.
The GBD 2023 study’s mental health burden estimates are not merely 'uncertain' but actively *erase* systemic solutions by framing cultural difference as a 'methodological challenge' rather than a political imperative.
This erasure is not accidental but rooted in a 500-year history of psychiatric colonialism, where non-Western emotional expressions were recoded as 'disorders' to justify cultural domination—a pattern that persists today in the study’s exclusion of Indigenous frameworks like *Hózhǫ́* or *Ubuntu*. The 'global' in GBD is a neocolonial fiction, masking how Western diagnostic criteria pathologize adaptive responses to structural violence (e.g., *karoshi* in Japan, *Susto* in Latin America) while ignoring how community-based care achieves better outcomes at lower costs. To correct this, mental health governance must shift from extractive metrics to *decolonized data sovereignty*, where Indigenous observatories and marginalized communities co-design burden estimates—turning the GBD’s 'burden' into a shared resource rather than a tool of pathological control.
