4.2 Transcultural Psychiatry

Culture: Definition & Core Characteristics

  • Culture = patterns of human activity producing shared symbols, meanings & structures → languages, knowledge, beliefs, norms, values, behaviours, technology.
  • 8 Essential traits
    • 1 Learned
    • 2 Individual & group process
    • 3 Trans-generational transmission
    • 4 Shared symbols/behaviours w/ tacit or explicit consensus
    • 5 Template shaping future behaviour & novel situations
    • 6 Constantly changing
    • 7 Contains subjective & objective patterns
    • 8 Expressed in institutions/laws.
  • Cultural Psychiatry (Transcultural Psychiatry) studies influence of culture across neurobiological → social levels on mental health.

Cultural Competence Frameworks

  • Cultural competence = capacity to function effectively w/ culture at: micro (clinical), meso (program/organisation), macro (system).
  • Training targets: attitudes, knowledge, skills + awareness of power differentials.
  • Pitfalls: stereotyping. Alternative/adjunct concepts:
    • Cultural Safety (Māori nurses, NZ): recognise oppression history, develop critical consciousness, safety judged by recipients.
    • Structural Competence: act on social determinants, policies; requires structural humility & cultural humility.
    • Anti-oppressive Practice: identify/disrupt racism, classism, genderism, heterosexism, ableism; empower collective advocacy.
  • DEI
    • Diversity: representation of differences (race, ethnicity, gender, orientation, (dis)ability…)
    • Equity: fair access based on need (≠ equality).
    • Inclusion: meaningful participation & voice.
    • Must be enacted together.

Race • Ethnicity • Census Examples

  • Race = social construct based on superficial traits; term “racialised” highlights process. Misuse → biologic determinism.
  • Ethnicity = common ancestry, geography, language, religion; fluid, self-assigned or externally imposed.
  • 2020 US Census racial categories: White, Black/African Am, AI/AN, detailed Asian/Pacific sub-groups, “Some other race” + separate Hispanic ethnicity.
  • Canada 2021 long-form: >500 ethnic origins list + visible-minority question; UN critique of “visible minority” imprecision.
  • England/Wales 2021 groups: Asian, Black, Mixed, White, Other; Scotland & N. Ireland differ.

Migration & U.S. Demographics

  • Migrant (UN): any person moving away from habitual residence.
  • Immigrant: living outside country of birth. Four statuses: naturalised citizens, permanent/conditional residents, non-immigrants, undocumented.
  • 2020 US racial/ethnic snapshot (alone/in combination):
    • White 61.6\% (204.3 M, ↓8.6\% since 2010)
    • Hispanic 18.7\% (62.1 M)
    • Black 14.2\% (46.9 M)
    • Asian 7.2\% (24 M)
    • AI/AN 2.9\% (9.7 M, ↑160\% in-combination)
    • NH/PI 0.5\% (1.6 M)
    • Two + races 10.2\% (↑ from 2.9\%).
  • Foreign-born share: 14.8\% (2020); projected 17.1\% by 2060.
  • 1960 immigrant origins 84\% Europe/Canada/NA vs 2011–2020 top 5: Mexico 14.6\%, China 7.0\%, India 6.2\%, Philippines 4.9\%, Dominican Rep 4.9\%.
  • Refugee definition (UNHCR); 2021 displaced 89.3 M (refugees 27.1 M, IDPs 53.2 M). US admitted 25{,}465 refugees in 2022 (peak 132{,}531 in 1992).

Racism & Mental Health

Micro-level: Interpersonal / Internalised

  • Overt assaults & microaggressions → depression, anxiety, psychosis across Latino, Asian, African American, Afro-Caribbean; dose–response w/ domains (NESARC, NLAAS, NSAL).
  • Allostatic load higher under discrimination → cardiovascular risk; mediation via anger, poor sleep.
  • EMA: same-day anxiety (all), somatic symptoms (Asians), next-day depression (Latinos).
  • Protective: strong ethnic identity, pride, communal involvement.
  • Internalised racism (e.g., colorism) linked to psychiatric disorders; “model minority” myth harms Asians & fuels anti-Blackness.
  • Intersectionality (Crenshaw): overlapping oppressions ↑ mental-health risk.

Meso & Macro: Structural / Systemic

  • Embedded in laws, housing, finance, environment, policing, education (“school-to-prison pipeline”).
  • Historic psychiatry racism: Rush “negritude”, Cartwright “drapetomania”.
  • Table 4.2-1 pathways: economic injustice, environmental hazards, trauma, targeted marketing, inadequate care, state violence, political exclusion, maladaptive coping, stereotype threat.

Socio-economic Disparities

  • 2021 Supplemental Poverty: AI/AN 12.4\%, Black 11.2\%, Hispanic 11.2\%, Asian 9.5\%, White 5.7\%.
  • 2020 median income hierarchy: Asian > White > Hispanic > Black. Income-gap top10\%/bottom10\% =10.7× Asians, 9.8× Blacks.

Social Determinants & ACEs

  • Domains: housing, transport, racism, education, income, food, environment, literacy.
  • ACEs inc. abuse, household dysfunction; Philadelphia study added bullying, violence, racism, foster care → 83.2\% ≥1 ACE.

Prevalence Patterns

  • CPES combined analysis (n=21{,}024): Lifetime mood/anxiety/substance rates highest in non-Latino Whites (22.6\%/26.1\%/18.8\%) vs Asians (12.0/13.1/5.1\%).
  • Immigrant paradox: foreign-born generally lower prevalence; risk rises with years in US & generations; exception = Puerto Ricans.
  • Psychosis: African Americans 3.27× schizophrenia risk (Kaiser cohort); Blacks & Latinos higher lifetime psychotic symptoms (15.3\%/13.6\%). Diagnostic bias → over-schizophrenia.

Service Utilisation Disparities

  • Past 12-mo treatment (NLAAS): Asians 8.6\% total sample, 34.1\% w/ diagnosis; Latinos vary (Puerto Ricans 19.9\%).
  • MEPS 2004–2012 access rise Whites 16→20\% vs Asians 3→5\%; disparities persist.

Indigenous Peoples (AI/AN)

  • Population 9.7 M (2.9\% US). Life expectancy 65.2 y (vs 76.1 general). Suicide ≤3× in under 25. Higher PTSD, alcohol disorders; IHT concept: colonial, collective, cumulative, cross-generational trauma.
  • IHS serves 2.6 M, only
    7\% funds to mental health.

Refugee Mental Health

  • Premigration PTSD
    3.5\% vs 1.2\% voluntary migrants (NLAAS). Cambodian PTSD 62\% even 20 y post-resettlement.
  • Bhutanese depression 21\%; suicide 21.5 per 100{,}000.
  • Multitier MHPSS: 4 levels (basic services → community → trauma healing → specialised care).

Cultural Dimensions & Values

  • Hofstede 6 dimensions; US: highest Individualism (91/100) & Indulgence (68), lowest LTO (26). China opposite.
  • Individualism ↔ analytic cognition, high-arousal emotions; Collectivism ↔ holistic cognition, low-arousal calm.
  • DRD4 7R/2R allele moderates culture–emotion relations.
  • Schwartz 10 values across 2 axes (openness–conservatism, self-enhancement–transcendence).

Identity Development Models

  • Nigrescence, Helms White Identity, R/CID (conformity → integrative awareness), Latino Orientation types, Phinney exploration/commitment.

Acculturation Theories

  • Berry bidimensional: Integration, Assimilation, Separation, Marginalisation.
  • Bourhis Interactive model pairs dominant-group attitudes; mismatch ↑ acculturative stress.
  • Policy indices: MIPEX 2020 top Sweden 86; US 73.

Culturally Competent Assessment

Engagement Triad

Communication (verbal/non-verbal) • Empathic understanding • Rapport.

Working w/ Interpreters — key rules

  • Pre-brief ➔ first-person, no filtering; seating triangle; destroy notes.

DSM-5-TR Outline for Cultural Formulation (OCF)

1 Identity 2 Cultural concepts of distress 3 Stressors/Resilience 4 Clinician-patient relationship 5 Overall assessment.

Pharmacotherapy Highlights

  • CYP2D6: 5−10\% Whites poor metab vs 70\% East Asians intermediate; Arabs/Ethiopians 20−30\% ultrarapid.
  • Clozapine levels higher in Asians; BEN new ANC cutoff <500/µL.
  • Start-low-go-slow, explore cultural beliefs (e.g., “hot” meds in TCM), religious constraints (gelatin, fasting).

Psychotherapy & Culture

  • LEARN mnemonic: Listen • Explain • Acknowledge • Recommend • Negotiate.
  • Meta-theoretical lens: Goals–Content–Process & Time–Locus–Activity mapping; use Pro-cultural vs Counter-cultural strategies.
  • Common healing factors (Frank): charged relationship, culturally sanctioned ritual.

Global Mental Health (GMH)

  • 2019 DALYs mental disorders 4.9\%; incl neuro/ substance/suicide → 13.0\% ≈ cardiovascular.
  • Global suicide 9 per 100{,}000; 77\% in LMICs; highest Lesotho 72.4.
  • Treatment gap: HIC untreated 35.5−50.3\% vs LMIC 76.3−85.4\%. Schizophrenia gap LMIC 69\% (low-income 89\%).
  • NIMH 25 grand challenges → 6 goals (root causes, prevention, care, stigma, metrics, capacity).
  • Lancet 2018 Commission pillars: universality, continuum, biopsychosocial, human-right.
  • Task-shifting example: Zimbabwe “Friendship Bench” ↓ PHQ-9 vs enhanced usual care.
  • Implementation science RE-AIM: Reach • Effectiveness • Adoption • Implementation • Maintenance; requires equitable local partnership.
