Global Mental Health: Globalization and Hazards to Women’s Health Anne E. Becker, M.D., Ph.D., Sc.M. October 15, 2009 SW 25
Global Mental Health Delivery Challenges: Quick Reprise & Overview Resource and allocation gaps • Suboptimal health financing and inequitable distribution • “Clinico-centric services” • Child mental health policy gap • Understanding their relation to social processes and to vulnerable & “undervisible” populations (e.g., women and adolescents) • Research & information gap • Operationalization of social predictors of risk & resilience • Assessment of mental illness outcomes
Global Mental Health Delivery Challenges: Quick Reprise & Overview Limitations of quantitative assessment • Uncertain validity of measurement • Selection and reporting biases (method and topic-dependent) • Perils of reductionism • Ethnocentrism, bias, and limited local relevance
Global Mental Health Delivery Challenges: Quick Reprise & Overview Limitations of mental health assessment • Uncertain fit of universal nosologic categories with local worlds and relevance • Implications for screening, prevalence estimates, relevance of interventions developed for other populations • Not only illness, but impairment, distress, course, and outcomes may be culturally particular Possible strategies to circumvent limitations?
Global Mental Health Delivery Challenges: Quick Reprise & Overview Limitations of qualitative assessment of mental health data • Disentangling signal from noise: the inherent “messiness” of field data • Imperfect access to inner experience • Positioned subjects • Limits to causal inference • Balance of action with scholarship
What about globalization and mental health? • What causal mechanisms link economic and social change to impact on health? • Who is vulnerable? • Social processes and associated health risks are dynamic
Why study mental health in Fiji? • Fiji is undergoing rapid social and economic change • Opportunity to understand impact of social adversity
How do we measure impact of socio-cultural environment on mental health?
Studies relating acculturation to eating pathology (n=29) Becker et al, 2009
Studies relating acculturation to eating pathology (n=29) Becker et al, 2009
Results of an exploratory factor analysis of items relating to 5 dimensions of *acculturation* Becker et al, in press
Intercorrelations among 12 dimensions of *acculturation* Note: *p<.05, **p<.01; ***p<.001; Traditional adherence dimensions shaded in light grey; overlapping traditional dimension cells shaded in dark grey. Note: ** p<.01; ***p<.001; Ethnic Fijian cultural dimensions are shaded in light grey; overlapping Ethnic Fijian cultural dimension cells are in shaded in dark grey. (Becker et al, in press)
Outcome misclassification • LeGrange and colleagues (2004) investigated the validity of high EAT-26 scores among impoverished black adolescents in South Africa
Outcome misclassification • EDE-Q was used as a gold standard for validation and was consistent with no eating disorder diagnosis in 2 of 5 study participants • Their response relating to food preoccupation turned out to have related to their poverty and hunger, not an eating disorder
Anorexia Nervosa without Fat Phobia • Lee and colleagues described anorexia nervosa without fat phobia in the 1990s • EAT-26 misclassified non fat phobic individuals as not having an eating disorder when they apparently did (Lee et al. 2002)
Eating Disorders as biosocial phenomena • Cultural diversity in aesthetic ideals • and what they mean
Eating Disorders as biosocial phenomena: Weight management behaviors are constrained by the social environment
Eating Disorders as biosocial phenomena Cultural diversity in idioms of distress and rhetoric for self-expression
Meta-analysis comparing AN with NFP-AN d = .27, p = ns (Becker, Thomas, & Pike, 2009)
Meta-analysis comparing AN with NFP-AN d = .65, p = .002 Significant difference holds even when constructs with no potential for overlap with fat phobia are excluded from the meta-analysis (d = .41, p = .04). (Becker, Thomas, & Pike, 2009)
DSM-IV Eating Disorder Categories Not Useful for Classifying Potential Cases Source and relevant discussion in: Thomas JJ, Crosby RD, Wonderlich SA, Striegel-Moore RH, Becker AE. A latent profile analysis of the typology of bulimic symptoms in an indigenous Pacific population: Evidence of cross-cultural variation in phenomenology. Under review at Psychological Medicine.
Etic perspective Universalizing versus local classification • The “outsider” perspective • Assumes a universal framework for illness • Attempts to identify the “true” core illness despite variations in epiphenomena
Emic perspective Universalizing versus local classification • The “local” perspective • Assumes a culturally particular and relativistic frame • Begins from the “ground up” with indigenous nosologic categories
An indigenous perspective on an illness episode: Macake Peri-orbital cellulitis Delirium Weight loss High fever Seizure Food Refusal

Cultural Norms vs. Symptoms Is binge-eating relative to its context?
Cultural Norms vs. Symptoms Is purging relative to its context?
So, in the universe of possible ED symptoms, where do we draw the line? Binge-eating Purging Weight loss Anorexia nervosa?/ EDNOS? Excess shape concern Food Refusal
Where do we draw the line? Bulimia nervosa?/ EDNOS? Binge-eating Purging Weight loss Excess shape concern Food Refusal
Where do we draw the line? Binge-eating Purging Weight loss Macake? Excess shape concern Food Refusal
Encompassing cultural diversity in DSM-V another empirical approach
Indigenous Herbs Facilitate Culturally Normative Purging • Purging with indigenous Fijian herbs reported in focus groups • Using herbs to induce vomiting or diarrhea, or clean out the stomach, is socially acceptable in Fiji • Added items to EDE and EDE-Q to assess herbal purgative use
LPA Identified Two Classes with Different Methods of Purging Multiple purging class (37%) (Data from Thomas et al, under review)
LPA Identified Two Classes with Different Methods of Purging Multiple purging class (37%) Herbal purging class (63%) (Data from Thomas et al, under review)
Herbal and Multiple Purging Classes Have Similar Levels of Eating Pathology EDE-Q Global a b b F = 13.72, p< .001, error bar = SE (Data from Thomas et al, under review)
Herbal and Multiple Purging Classes Have Similar Levels of Dysphoric Affect CES-D a b b F = 5.88, p< .01, error bar = SE (Data from Thomas et al, under review)
Herbal Purging Class Exhibits Greater Impairment Than Multiple Purging Class CIA a a b F = 6.12, p< .01, error bar = SE (Data from Thomas et al, under review)
Conclusions about Eating Disorder Nosology from Fiji No, despite high rates of individual ED symptoms, DSM-IV categories did not detect any eating disorder cases • Are DSM-IV eating disorder categories useful for classifying potential cases in Fiji? • Yes, latent profile analysis identified two classes associated with impairment and pathology: • Multiple purging class • Herbal purging class • Can a more culturally sensitive and locally meaningful classification be empirically derived through latent profile analysis?
Eating Disorders: Can the DSM V have Global Clinical Utility? • Attunement to diverse cultural patterning of symptoms and local social norms • Locally valid assessment of population and individual risk • Consideration of emerging risk in populations undergoing rapid economic transition • Emphasis of fluidity of social norms
Back story narrative: Violence and despair • 117 (23%) girls reported seriously considering killing themselves in the past year • 15% (80) girls reported a physical attack in the past year
