Internalized-Racism Stress Screen with At-Home Cortisol Confirmation

Concept

A two-step screening product for community health centers, well-woman clinics, and public-health programs serving African-Caribbean and Black women.

Step 1 — Psychosocial screen (tablet or paper, ~10 minutes): a short battery combining an internalized racism (INR) scale, the Perceived Stress Scale (PSS), and the defeated-coping items ("restraint," "denial," "behavioral disengagement") identified in the source study. The screen's logic comes directly from the paper's structure: perceived stress and defeated coping tracked cortisol dysregulation only among women with high internalized racism — so INR is the stratifier that determines whose stress report is biologically meaningful.

Step 2 — Confirmation: women screening high (high INR plus elevated stress/defeated coping) receive a take-home saliva kit with two collections — morning (~8:30 am) and night (~10:30 pm), mirroring the study protocol — processed by a partner lab into a cortisol profile.

Output: a one-page plain-language report for the woman and her clinician showing the cortisol profile, coping-style flags, and concrete next steps: a culturally appropriate stress-management referral plus metabolic follow-up (waist circumference, fasting glucose/HbA1c), since the underlying pathway points to abdominal obesity and glucose intolerance.

The single wedge: converting "I'm stressed" into a racism-contextualized, biologically confirmed risk flag that justifies early metabolic monitoring — before disease, not after.

Why now

• The new study [0], on age- and BMI-matched nondiabetic African-Caribbean women aged 25–60 in Dominica (high-INR n=27, low-INR n=26), found that high-INR women reported higher perceived stress and more defeated coping (restraint, denial, behavioral disengagement), and that perceived stress and defeated coping correlated significantly with an indicator of cortisol dysregulation — a correlation that, adjusted for age and education, held only in the high-INR group. That is exactly the moderation structure a two-step screen needs: a questionnaire variable that identifies whose stress physiology is at risk.
• The same paper notes prior findings that African-Caribbean women with high internalized racism are at increased risk of abdominal obesity and glucose intolerance — giving the screen a concrete metabolic follow-up target.
• The measurement is field-proven and cheap: the study collected usable 8:30 am / 10:30 pm salivary cortisol from 53 women on a small island — no phlebotomy, no wearables — so the screen is deployable in low-resource community settings.
• Older corpus work supplies the downstream plausibility: HPA-axis and glucocorticoid-receptor dysfunction tie stress to inflammatory and metabolic disease [1], and adiposity-driven inflammation and oxidative stress are precursors of insulin resistance, hypertension, and dyslipidemia [4].
• Claims are sized to the evidence: this is a pilot-ready risk screen for community-scale deployment, not a diagnostic — the source study is a single 53-woman field study, so the product's first market is community health programs willing to validate at scale.
