Lifetime and twelve-month prevalence rates of major depressive episodes and dysthymia among Chinese Americans in Los Angeles

Validation of the Beck Depression Inventory for a Portuguese-speaking Chinese community in Brazil

The objective of the present study was to investigate the psychometric properties and cross-cultural validity of the Beck Depression Inventory (BDI) among ethnic Chinese living in the city of São Paulo, Brazil. The study was conducted on 208 community individuals. Reliability and discriminant analysis were used to test the psychometric properties and validity of the BDI. Principal component analysis was performed to assess the BDI's factor structure for the total sample and by gender. The mean BDI score was lower (6.74, SD = 5.98) than observed in Western counterparts and showed no gender difference, good internal consistency (Cronbach's alpha 0.82), and high discrimination of depressive symptoms (75-100%). Factor analysis extracted two factors for the total sample and each gender: cognitive-affective dimension and somatic dimension. We conclude that depressive symptoms can be reliably assessed by the BDI in the Brazilian Chinese population, with a validity comparable to that for international studies. Indeed, cultural and measurement biases might have influenced the response of Chinese subjects.

Mental health care for ethnic minority individuals and communities in the aftermath of disasters and mass violence

Findings from research on psychiatric epidemiology, disaster effects, discrepancies in service use, and cross-cultural psychology are reviewed to generate guidelines for culturally responsive postdisaster interventions. Ethnicity and culture influence mental health care at various points: on need for help; on availability and accessibility of help; on help-seeking comfort (stigma, mistrust), and on the probability that help is provided appropriately. There are aspects of disaster mental health practice that may ameliorate many of barriers that contribute to ethnic disparities in service use. It is proposed that interventions should give greater attention to socially engaged emotions and functioning. To promote disaster recovery, practitioners are advised to: assess community needs early and often; provide easily accessible services; work collaboratively and proactively to reduce stigma and mistrust and engage minorities in care; validate and normalize distress and help-seeking; value interdependence as well as independence as an appropriate developmental goal; promote community action; and advocate for, facilitate, or conduct treatment and evaluation research. Notwithstanding the pain and stress they cause, disasters create opportunities to de-stigmatize mental health needs and build trust between providers and minority communities.

Depressive symptoms among women with an abnormal mammogram

An abnormal mammography finding constitutes a stressful event that may increase vulnerability by developing or intensifying pre-existing psychological morbidity. We evaluated depressive symptoms using the Composite International Diagnostic Interview among women of four ethnic groups who had an abnormal mammography result controlling for the effect of demographic, psychosocial and medical factors on recent onset of depressive symptoms. Telephone surveys were conducted among women aged 40-80 years recruited from four clinical sites in the San Francisco Bay Area after receiving a screening mammography result that was classified as abnormal but probably benign, suspicious or highly suspicious, or indeterminate using standard criteria. Among the 910 women who completed the interview, mean age was 56 (S.D.=10), 42% were White, 19% Latina, 25% African American, and 14% Asian. Prevalence of lifetime depressive symptoms was 44%, and 11% of women had symptoms in the previous month. Multivariate logistic regression models showed that Asian ethnicity, annual income >$10 000 and weekly attendance at religious services were significantly associated with decreased depressive symptoms. Having an indeterminate result on mammography and being on disability were significantly associated with more depressive symptoms. Reporting a first episode of depression more than a year before the interview was associated with significant increase in depressive symptoms in the month prior to the interview regardless of mammography result. Women with an indeterminate interpretation on mammography were at greater risk of depressive episode in the month prior to the interview compared to women with probably benign results (odds ratio=2.41; 95% CI=1.09-5.31) or with a suspicious finding. Clinicians need to consider depression as a possible consequence after an abnormal mammography result.

Age of First Onset Major Depression in Chinese Americans

Using data from the Chinese American Epidemiological Study, risk for experiencing an initial episode of major depression across the life course was examined. Data were collected on 1,747 U.S.-born and foreign-born Chinese Americans (ages 18-65 years). Results suggest that Chinese American women did not evidence higher risk than Chinese American men for experiencing a 1st major depressive episode. Risk for experiencing a 1st depressive episode decreased as length of residence in the United States increased. Although those who immigrated at younger ages evidenced greater overall risk, those who came at later ages were more likely to become depressed at or soon after arrival. Competing theories of acculturation-related risk are discussed and directions for future research are proposed.

The phenomenon of somatization among community Chinese Americans

OBJECTIVE

The phenomenon of somatization was explored in relation to the experiences of acculturation, stress, support, and distress.

METHODS

A representative community sample of 1,747 Chinese Americans (aged 18-65 years), selected by a multi-stage household sampling design, in the Los Angeles County was interviewed to tap their psychiatric diagnoses, symptomatology, level of acculturation, stress, and support.

RESULTS

Across all indices, Chinese Americans' level of somatic symptoms, impairment related to somatization, and percentage of meeting the Somatic Symptom Index 5/5 (SSI 5/5) criterion were comparable to those found in other populations. Length of residence in the U. S. and acculturation were not related to somatization. Regression analyses showed that anxiety, depression, gender, age, education, stressors, and support were significantly related to somatization, ps < 0.05. Somatizers tended to perceive themselves with poor health and utilized both Western and indigenous Chinese medicine.

CONCLUSION

The importance of demographics, psychological distress, and stress was emphasized in the explanation of somatization tendencies among immigrant Chinese Americans. Somatization might be a stress response with regard to increased distress severity and psychosocial stressors rather than a cultural response to express psychological problems in somatic terms.

Racial/ethnic differences in the prevalence of depressive symptoms among middle-aged women: The Study of Women's Health Across the Nation (SWAN)

OBJECTIVES

We examined racial/ethnic differences in significant depressive symptoms among middle-aged women before and after adjustment for socioeconomic, health-related, and psychosocial characteristics.

METHODS

Racial/ethnic differences in unadjusted and adjusted prevalence of significant depressive symptoms (score >/= 16 on the Center for Epidemiologic Studies Depression [CES-D] Scale) were assessed with univariate and multiple logistic regressions.

RESULTS

Twenty-four percent of the sample had a CES-D score of 16 or higher. Unadjusted prevalence varied by race/ethnicity (P <.0001). After adjustment for covariates, racial/ethnic differences overall were no longer significant.

CONCLUSIONS

Hispanic and African American women had the highest odds, and Chinese and Japanese women had the lowest odds, for a CES-D score of 16 or higher. This variation is in part because of health-related and psychosocial factors that are linked to socioeconomic status.

Traffic stress, vehicular burden and well-being: a multilevel analysis

This study examined whether health is associated with individually perceived traffic stress and as well as ecologically measured vehicular burden using multi-level analysis. Data from the Chinese American psychiatric epidemiologic study (N = 1503) are linked to data from the 1990 Census in the United States. Hierarchical linear modeling was used to analyze the cross-sectional relationship between traffic stress, neighborhood conditions, depression and health status. Perceived traffic stress is associated with both general health status and depression in multivariate multilevel models, such that persons reporting traffic stress had lower health status and more depressive symptoms. Further, there is an interaction between vehicular burden and traffic stress for both health outcomes. Persons who lived in areas with greater vehicular burden and who reported the most traffic stress also had the lowest health status and greatest depressive symptoms. These findings suggest that traffic stress may represent an important factor that influences the well-being of urban populations, and that studies which examine factors at only one level (either individual level only or ecological level only) may underestimate the effect of the social environment.

Assuring the health of immigrants: what the leading health indicators tell us

Over the past 20 years, the United States has experienced one of the largest waves of immigration in its history. Understanding the health status and needs of immigrants is important because of their growing numbers and their contribution to the health of the nation, but it is challenging because of gaps in national databases, the heterogeneity of immigrant populations, and uncertainty about how migration affects health. Healthy People 2010 outlines the nation's public health objectives for the current decade. It includes ten leading health indicators (LHIs) chosen because of their importance as public health issues, their ability to motivate action, and the availability of data to measure their progress. In this paper, we discuss the health of immigrants from the perspective of these LHIs, as they provide a framework for anticipating some of the future health needs of immigrants and help define priority areas for research and action.

Effect of discrimination on mental health service utilization among Chinese Americans

OBJECTIVES

We examined the association between discrimination and mental health service use among a representative sample of Chinese Americans.

METHODS

Our data were derived from the 2-wave Chinese American Psychiatric Epidemiological Survey, a strata-cluster survey conducted in 1993 and 1994 in a western American city.

RESULTS

Language-based discrimination was associated with higher levels of use of informal services and seeking help from friends and relatives for emotional problems. Negative attitudes toward professional mental health services were associated with greater use of informal services.

CONCLUSIONS

The findings suggest that language-based discrimination influences patterns of mental health service use among Chinese Americans. Implications for service providers and policymakers are discussed.

Some recommendations to assess depression in Chinese people in Australasia

OBJECTIVE

To provide some general recommendations for psychiatric assessment of depression among Chinese patients within a predominately Western society.

METHOD

A literature review is provided with interpretive comments.

RESULTS

The prevalence of depression reported in community studies undertaken in Chinese communities is very low. To what extent Chinese people experience and seek help for depression, and how they report depressive symptoms have long been topics of some importance. The impact of acculturation as well as concepts and interpretations of illness in traditional Chinese medicine are discussed. Awareness of sensitive issues and practices within the Chinese culture will facilitate communication between medical professionals and patients, resulting in more accurate identification and diagnosis of depressive disorders.

CONCLUSION

Direct but culturally sensitive and empathic questioning of psychological symptoms is needed to unveil patients' explanatory models, as most Chinese initially nominate only somatic symptoms to health practitioners. Successfully treated patients can promote earlier and wider utilization of mental health services to other Chinese people.

Prevalence and incidence studies of mood disorders: a systematic review of the literature

OBJECTIVE

To present the results of a systematic review of literature published between January 1, 1980, and December 31, 2000, that reports findings on the prevalence and incidence of mood disorders in both general population and primary care settings.

METHOD

We conducted a literature search of epidemiologic studies of mood disorders, using Medline and HealthSTAR databases and canvassing English-language publications. Eligible publications were restricted to studies that examined subjects aged at least 15 years and over. We used a set of predetermined inclusion and exclusion criteria to identify relevant studies. We extracted and analyzed prevalence and incidence data for heterogeneity.

RESULTS

Of general population studies, a total of 18 prevalence and 5 incidence studies met eligibility criteria. We found heterogeneity across 1-year and lifetime prevalence of major depressive disorder (MDD), dysthymic disorder and bipolar I disorder. The corresponding pooled rates for 1-year prevalence were 4.1 per 100, 2.0 per 100, and 0.72 per 100, respectively. For lifetime prevalence, the corresponding pooled rates were 6.7 per 100, 3.6 per 100, and 0. per 100, respectively. Significant variation was observed among 1-year incidence rates of MDD, with a correspond ing pooled rate of 2.9 per 100.

CONCLUSIONS

The prevalence of mood disorders reported in high-quality studies is generally lower than rates commonly reported in the general psychiatric literature. When controlled for common methodological confounds, variation in prevalence rates persists across studies and deserves continued study. Methodological variation among studies that have examined the prevalence of depression in primary health care services is so large that comparative analyses cannot be achieved.

Prevalence of major depressive disorder among Chinese-Americans in primary care

An epidemiological study in Los Angeles showed that Chinese Americans had lower rates of depression compared to the U.S. national estimates. This study surveys the prevalence of major depressive disorder (MDD) among Asian-Americans in the primary care setting. A two-phase epidemiological survey was performed in the primary care clinic of a community health center in Boston, MA, which provides treatment to under-served Asian-Americans. Participants were Chinese Americans in the waiting area of the primary care clinic, 18 years of age or older, who spoke any one the four commonly used Chinese dialects. The Chinese version of the Beck Depression Inventory (CBDI) was used for initial screening. All consenting patients who screened positive (CBDI >/= 16) and a fraction of those who screened negative (CBDI < 16) were interviewed by a bilingual and bicultural psychiatrist with the Structured Clinical Interview for DSM-III-R, patient version, for confirmation of the diagnosis of MDD. There were 815 in the primary care clinic that were approached, of which 503 patients (62% female, mean age 50 +/- 17 years) filled out the CBDI in the initial phase of depression screening. Extrapolating the results from the SCID-P interviews, the prevalence of MDD among Asian-Americans in the primary care setting was estimated to be 19.6% +/- 0.06. MDD is common among Asian-Americans in primary care settings. The prevalence of MDD is comparable to or higher than those found in the U.S. nonminority populations.

Cultural relevance and equivalence in the NLAAS instrument: integrating etic and emic in the development of cross-cultural measures for a psychiatric epidemiology and services study of Latinos

This paper describes the development, translation and adaptation of measures in the National Latino and Asian American Study (NLAAS). We summarize the techniques used to attain cultural relevance; semantic, content and technical equivalency; and internal consistency of the measures across languages and Latino sub-ethnic groups. We also discuss some of the difficulties and thallenges encountered in doing this work. The following three main goals are addressed in this paper: (1) attaining cultural relevance by formulating the research problem with attention to the fundamental cultural and contextual differences of Latinos and Asians as compared to the mainstream population; (2) developing cultural equivalence in the standardized instruments to be used with these populations; and (3) assessing the generalizability of the measures - i.e., that the measures do not fluctuate according to culture or translation. We present details of the processes and steps used to achieve these three goals in developing measures for the Latino population. Additionally, the integration of both the etic and emic perspectives in the instrument adaptation model is presented.

Smoking and depression in Chinese Americans

BACKGROUND

A close link between smoking and depression has been documented by research primarily based on U.S. white populations. This study examined the association between depressive symptoms and smoking behaviors in Chinese American smokers.

METHODS

Analyses were based on baseline data collected from a convenience sample of 199 Chinese smokers who resided in northern California. The sample included 20.6% women, 97% immigrants, with mean age of 40.8 years and mean cigarettes/day of 8.9.

RESULTS

Compared with population-based studies of Chinese Americans, the Chinese smokers in the current study reported higher depressive symptoms assessed by the Center for Epidemiologic Studies-Depression Scale [M, 20.4; 95% confidence interval (CI), 18.8-22.2], higher lifetime prevalence rates of major depressive disorders (30.3%; 95% CI, 24.0-37.2%) and dysthymia (11.6%; 95% CI, 7.5-16.9%). Multiple regression analysis suggested female gender, unemployment, major depression or dysthymia within the past year, previous experience with nicotine withdrawal syndrome, and high temptation to smoke under negative affect situations are associated with a higher level of depressive symptoms.

CONCLUSIONS

The level of depressive symptoms among Chinese American smokers is comparable with that observed in other US populations reported. In the current sample, elevated depressive symptoms were more prominent among women or those who were unemployed, smokers who reported significant nicotine withdrawal at previous quit attempts, and high temptation to smoke when experiencing negative emotions. Findings support further examination of the role of depression in smoking among Chinese Americans and underscore the importance of addressing depressive symptoms when treating tobacco use in Chinese smokers.

Partner violence and major depression in women: a community study of Chinese Americans

This cross-sectional, retrospective study used epidemiological and anthropological methods toward two aims: 1) to examine associations between partner violence and major depression in a community probability sample of women and 2) to provide new data on partner violence in Chinese Americans. In this study, 181 Chinese American women were interviewed, with 178 completing structured sections on CIDI 2.1 major depression and on partner violence history. Results indicate that a history of partner violence is associated with significantly higher rates of lifetime, 12-month, and current major depression in this community population. This effect is specific and independent of other factors. Partner violence also has a dose-response relationship with the severity of major depression episodes, increasing risk for severe and moderate episodes. The strength and specificity of this association, its dose-response effect, and its commonality across different populations suggest a possible causal role for partner violence needing further investigation in research on major depression in women.

Cultural specificity and comparison in psychiatric epidemiology: walking the tightrope in American Indian research

Increasingly, the mental health needs of populations are measured using large-sample surveys with standardized measures and methods. Such efforts, however, rarely include sufficient number of smaller, culturally defined populations to draw defensible conclusions about their needs. Furthermore, without some adaptation, the standardized methods and measures may yield invalid results in such populations. Using a recently completed psychiatric epidemiology and services study with American Indian populations as a case example, this paper outlines issues facing epidemiologists working in such culturally diverse contexts. The issues discussed include the following: (1) persuading the scientific community and potential sponsors that work with distinct or culturally defined populations is important; (2) framing research questions and activities to meet the needs of communities; (3) defining a population of inference; (4) balancing the needs for comparability and cultural specificity; (5) maximizing scientific validity in light of the challenges in sample acquisition; and (6) developing and implementing data collection methods that uphold scientific standards but are also realistic given the context. The authors draw on their experiences--most recently in the American Indian Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project (AI-SUPERPFP)--to illustrate these issues and suggest ways to address each. A goal of this paper is to challenge those invested in conducting culturally valid epidemiologic work in such populations to better articulate the nature of these efforts.

Psychosocial factors in chronic fatigue syndrome among Chinese Americans: a longitudinal community-based study

Chronic fatigue syndrome (CFS) is a relatively new condition of unknown etiology. Research suggests that psychosocial factors such as perceived social support, life stress, and acculturation may significantly influence individuals who are prone to CFS. For 57 Chinese American individuals initially diagnosed with CFS, those who recovered after one year reported lower levels of life stress than those who did not recover. Effects of changes in perceived social support also appeared to be mediated by life stress.

Measuring culture: a critical review of acculturation and health in Asian immigrant populations

The number of studies examining how acculturation affects the health of Asian immigrants has increased in recent years. The proliferation of studies reflects the growing size and heterogeneity of Asian immigrant populations in the United States, Canada, Australia, New Zealand, and the United Kingdom. This paper compares various approaches to acculturation within the health literature on Asian immigrants by reviewing the literature in three-health domains (1) mental health (2) physical health and (3) health services use. The review critically examines the conceptualizations and measures of acculturation in these three domains and presents major findings. We observe that measurement difficulties posed by the experiences of heterogeneous Asian groups compound theoretical and disciplinary disparities between acculturation instruments. The extent to which conceptual and methodological critiques of acculturation studies in Hispanic populations apply to studies of Asian populations is also discussed. The critical review thus provides insights into the diverse ways that the relationship between culture and health is measured in this complicated and growing literature.

Depression, anxiety, and associated health status in low-income Chinese patients

BACKGROUND

Little is known about the prevalence of mental disorders and the associated impact on health status in low-income immigrant Chinese Americans.

METHODS

This cross-sectional study surveyed low-income Chinese patients attending a community health center in Chinatown (New York City) from July through November 2001 to determine the prevalence of depressive and anxiety disorders. Selected modules translated into Chinese from the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire (PHQ), a self-administered measure designed to diagnose mental health disorders in primary care, were used. To assess the relationship between mental disorders and health status and to examine convergent validity, mean scores on the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) were examined according to PHQ diagnoses and calculated severity of depression.

RESULTS

A total of 856 patients were approached and data were obtained from 523 (61%) eligible participants. Thirty-two (6.1%) patients met the established criteria for major depressive disorder; 26 (5.0%) patients met the criteria for other depressive disorder; and 24 (4.6%) patients met the criteria for other anxiety disorder. Compared to patients without depression or anxiety, patients with major depressive and other anxiety disorder had significantly lower mean scores on all eight SF-36 subscales, while patients with other depressive disorder had lower mean scores on all subscales except for physical functioning. SF-36 subscale scores tended to decrease with increasing depression severity.

CONCLUSIONS

Depression and anxiety were prevalent and demonstrated an adverse impact on health status, as measured by the SF-36. Strategies for screening for mental disorders may vary depending on the needs of the primary care setting and may be accomplished using a general health status measure or a disease-specific approach.

Overcoming barriers to reducing the burden of affective disorders

Affective disorders impose a substantial individual and societal burden. Despite availability of efficacious treatments and practice guidelines, unmet need remains high. To reduce unmet need and the burden of affective disorders, information is needed on the distribution of burden across stakeholders, on barriers to reducing burden, and on interventions that effectively reduce burden at the levels of practice, community, and policy. This article provides the report of the Working Group on Overcoming Barriers to Reducing the Burden of Affective Disorders, for the National Institute of Mental Health Strategic Plan on Mood Disorders. We review the literature, identify key gaps, and recommend new research to guide national efforts to reduce the burden of affective disorders.

A multilevel analysis of the relationship between institutional and individual racial discrimination and health status

OBJECTIVES

This study examined whether individual (self-perceived) and institutional (segregation and redlining) racial discrimination was associated with poor health status among members of an ethnic group.

METHODS

Adult respondents (n = 1503) in the cross-sectional Chinese American Psychiatric Epidemiologic Study were geocoded to the 1990 census and the 1995 Home Mortgage Disclosure Act database. Hierarchical linear modeling assessed the relationship between discrimination and scores on the Medical Outcomes Study Short-Form 36 and revised Symptom Checklist 90 health status measures.

RESULTS

Individual and institutional measures of racial discrimination were associated with health status after control for acculturation, sex, age, social support, income, health insurance, employment status, education, neighborhood poverty, and housing value.

CONCLUSIONS

The data support the hypothesis that discrimination at multiple levels influences the health of minority group members.

Screening for major depression in Asian-Americans: a comparison of the Beck and the Chinese Depression Inventory

OBJECTIVE

This study compares the effectiveness of the Chinese version of the Beck Depression Inventory (CBDI) and the Chinese Depression Inventory (CDI) in screening for depression among Chinese Americans.

METHOD

Five hundred and three Chinese-Americans in primary care were administered the CBDI and the CDI for depression screening. The results were compared with standard semistructured interview.

RESULTS

With empirically determined cutoff scores of the CBDI (> or =13) and the CDI (>/=16), both instruments have good sensitivity (0.78) and excellent specificity (0.91 and 0.93, respectively). The correlation between the total scores of the two instruments was high (0.785, P < 0.01). The areas under the Receiver Operating Characteristic (ROC) curve of the CBDI and the CDI were 0.94 and 0.95, respectively, and were not significantly different.

CONCLUSION

When administered by interviewers, the CBDI and the CDI have comparable effectiveness. Low participation among Chinese-Americans with self-report measures limits both scales as efficient depression screening instruments.

Posttraumatic stress symptoms and victimization among Japanese American women

This study of Japanese American women and immigrant women from Japan investigated the relationship between posttraumatic stress (PTS) symptoms and the perceived abusiveness of partners' emotional and physical violence, with a community-based randon sample. Women who experienced injuries and/or fear for their lives, in addition to partners' emotional and physical violence, had significantly higher PTS symptom counts than those with no lifetime experience of partners' violence. Victimization by nonintimates also increased PTS symptom counts. Satisfaction with social support significantly mitigated the negative effect of childhood abuse for reexperiencing and avoidance symptoms.

Use of the Chinese version of the Beck Depression Inventory for screening depression in primary care

Many Asian-Americans are unfamiliar with depression and its treatment. When depressed, they generally seek treatment from their primary care physicians and complain about their physical symptoms, resulting in under-recognition and under-treatment of depression. This study evaluates the effectiveness of the Chinese version of the Beck Depression Inventory (CBDI) for screening depression among Chinese-Americans in primary care. A total of 503 Chinese-Americans in the primary care clinic of a community health center were administered the CBDI for depression screening. Patients who screened positive (CBDI > or = 16) were interviewed by a psychiatrist using the Structured Clinical Interview for DSM-III-R, patient version (SCID-I/P) for confirmation of the diagnosis. Patients who screened negative (CBDI < 16) were randomly selected to be interviewed using the depression module of the SCID-I/P. The results of the SCID-I/P interview were used as the standard for evaluating the sensitivity and specificity of the CBDI. A total of 815 Chinese-Americans in a primary care clinic were approached, and 503 completed the CBDI. Seventy-six (15%) screened positive (CBDI > or = 16), and the prevalence of major depression was 19.6% by using extrapolated results from SCID-I/P interviews. When administered by a native-speaking research assistant, the CBDI has good sensitivity (.79), specificity (.91), positive predictive value (.79), and negative predictive value (.91). Despite the commonly believed tendency to focus on physical symptoms rather than depressed mood, Chinese-Americans are able to report symptoms of depression in response to a questionnaire. The CBDI, when administered by research assistants, has good sensitivity and specificity in recognizing major depression in this population. Lack of interest among Chinese-American patients in using the CBDI as a self-rating instrument has limited its use for depression screening in primary care settings.

Cultural, psychological, and demographic correlates of willingness to use psychological services among East Asian immigrants

To assess East Asian immigrants' willingness to use psychological services if depressed and willingness to recommend psychological services to distressed friends, and to examine their cultural (acculturation status, self-construal, ethnic identity), psychological, and demographic correlates, 170 East Asian immigrants (88 male, 82 female) were administered a battery of psychometrically established measures. Approximately 50% of participants expressed strong unwillingness to seek psychological treatments, and approximately 30% expressed strong unwillingness to recommend such treatments to distressed friends. Personal willingness to use psychological services was positively associated with assimilation, being female, age, and English fluency, but was negatively associated with interpersonal distance and number of years in the United States. In contrast, willingness to recommend psychological services to friends was positively associated with independent self-construal, overall ethnic identity, interpersonal sensitivity, being female, and number of years in the United States but was negatively associated with interpersonal distance and reported obsessive-compulsive symptoms. A minority of East Asian immigrants report being willing to seek or to recommend psychological services. Psychological distress, and cultural and demographic features were differentially associated with willingness to seek versus willingness to recommend psychological services.

Clinical features of dysthymia and age: a clinical investigation

A few authors have described the clinical picture of dysthymia in groups of elderly patients and pointed out differences from literature reports of dysthymia in younger adults. The present study, an attempt to analyze age effects on clinical characteristics of dysthymia throughout a lifetime, was performed in a sample of 106 patients, all aged > or =18 years, who were diagnosed according to DSM-IV. The patients were evaluated using: (1) a semistructured interview to assess clinical features, family history and previous treatments; (2) the Hamilton Depression Rating Scale; (3) the Interview for Recent Life Events; and (4) the Structured Clinical Interview for DSM-IV Disorders. Statistical analysis with stepwise logistic regression revealed that age was positively related to concomitant medical illnesses and to the total score of recent life events, but negatively related to the presence of avoidant or dependent personality disorders. The data suggested different etiologic pathways in older and younger patients. Dysthymia appeared to be associated in younger adults with abnormalities of personality; in the elderly, with a history of health problems and life losses.

Holding on and letting go: identity and acculturation among Chinese immigrants

This study addresses the general question of whether ethnic identity and general acculturation would prove unique discriminators of quality of life for Chinese immigrants. Eighty-three Chinese immigrants served as participants. Survey data were collected regarding acculturation, Asian identity, and quality of life; observers provided ratings of certain home environment characteristics; and participants responded to open-ended interview questions about their immigration experiences that allowed for qualitative data analysis on perspectives of culture. Significant analysis of covariance and post hoc comparison results revealed meaningful main effects and interactions between acculturation and Asian identity in explaining the immigrants' quality of life and ecocultural aspects of their home environments. Interview responses illuminated important distinctions between groups distinguished by level of acculturation and ethnic identity. Findings are discussed in terms of methodological and conceptual issues in studying acculturation and ethnic identity in immigration experiences and practical implications for immigrants and those working with them.

A structural model of acculturation and mental health status among Chinese Americans

This study examined the role of acculturation and its direct and indirect impact on depressive symptom severity through various correlates, including socioeconomic status (SES), stress, social support, personality negativity, and physical health perception. Using structural equation modeling, the proposed model was tested with 983 employed Chinese Americans from a representative community sample, the majority of whom were immigrants. The results demonstrated that acculturation, correlated with SES, contributed to depressive symptom severity only through indirect pathways. Higher acculturation was found associated with higher stress that in turn contributed to more elevated depressive symptoms. On the other hand, higher acculturation was also found strongly correlated with higher SES, which was associated with lower depressive symptoms directly or indirectly through several mediators. Better support, lower personality negativity, better health perception, and lower stress were found mediating the relationship between higher SES and lower depressive symptom severity. The simultaneous multigroup analysis showed that the final model was comparable for both men and women with very few differences.

Cultural psychopathology: uncovering the social world of mental illness

We review cultural psychopathology research since Kleinman's (1988) important review with the goals of updating past reviews, evaluating current conceptualizations and methods, and identifying emerging substantive trends. Conceptual advances are noted, particularly developments in the definition of culture and the examination of both culture-specific and cultural-general processes. The contributions of the Culture and Diagnosis Task Force for DSM-IV and the World Mental Health Report are reviewed and contrasted. Selected research on anxiety, schizophrenia, and childhood disorders is examined, with particular attention given to the study of ataque de nervios, social factors affecting the course of schizophrenia, and cross-national differences in internalizing and externalizing problems in children. Within the last ten years, cultural psychopathology research has become a significant force. Its focus on the social world holds promise to make significant inroads in reducing suffering and improving people's everyday lives.

Parenting practices and adolescent depressive symptoms in Chinese American families

This study examined parenting practices and adolescent depressive symptoms among Chinese Americans. First, confirmatory factor analyses revealed that self-reported parenting practices by mothers and fathers and adolescent perception of parenting practices loaded adequately on three subscales: Inductive Reasoning, Monitoring, and Harsh Discipline. Second, parents' depressive symptoms were related to disrupted parenting practices, which, in turn, were significantly related to the negative evaluation of these behaviors by the adolescents. Adolescents' perceptions of such parenting practices were significantly associated with their depressive symptoms. Third, the relationships were robust even after parental income, education, and generation status were statistically controlled. Overall, the relationships between parenting practices and adolescent depressive symptoms among Chinese Americans seemed to echo those found among European Americans.

The influence of ethnicity and antidepressant pharmacogenetics in the treatment of depression

Antidepressant disposition can be influenced by a variety of CYP isozymes and their effects in the treatment of depression are reviewed. The CYP isozymes 2D6, 3A4, 1A2 and 2C are discussed in regard to antidepressant drug pharmacokinetics, clinical relevance and variability in activity for each isozyme. Polymorphism has been identified with CYP 2D6 and 2C19. Disposition of antidepressants which are substrates of these two isozymes can also be influenced and contributes towards the wide interpatient and interethnic variability found with these drugs. Antidepressants (especially SSRIs) can be CYP isozyme inhibitors and produce significant drug-drug interactions.

SF-36 health survey: tests of data quality, scaling assumptions, and reliability in a community sample of Chinese Americans

BACKGROUND

Chinese Americans are one of the fastest growing ethnic groups in the United States; however, language and cultural obstacles have challenged health workers and policy makers seeking to understand the health status and needs of this population.

OBJECTIVES

This study is the first to use a large-scale probability design to evaluate the 36-item Short-Form Health Survey (SF-36) in a Chinese population (n = 1,501).

METHODS

Using the International Quality of Life Assessment Project protocols, we examine summated-rating scaling assumptions, item-internal consistency, item-discriminant validity, and reliability.

RESULTS

Similar to previous studies, our tests indicated that the SF-36 generally met minimum psychometric criteria with high reliability and satisfactory scaling success rates for most scales. However, the performance of the vitality and mental health scales was less satisfactory with regard to discriminant validity and scaling success rates. Notably, our results indicate that VT3 and VT4 ("feel worn out" and "tired", respectively) formed a separate "fatigue" cluster more highly correlated with the mental health scale. However, MH4 and MH5 ("downhearted and blue" [reverse coded] and "been a happy person") were more highly correlated with the vitality scale, suggesting that it may be more meaningful to reorganize the vitality and mental health items along the dimensions of well-being and distress.

CONCLUSIONS

These results are interpreted within a cultural framework; however, additional work is needed to better understand the relationship between vitality and mental health for Chinese Americans.

Relationship between ethnicity and sleep patterns in normal controls: implications for psychopathology and treatment

The purpose of the study was to examine ethnic influences on sleep regulation. Seventy-three normal volunteers from four ethnic groups (17 African-Americans, 10 Asians, 30 Caucasians and 16 Hispanics) were studied for two consecutive nights with sleep polysomnography recordings in the laboratory. The subjects were in good physical and psychological health, and were asymptomatic with respect to sleep/wake complaints or sleep disorders. With the exception of minor differences, sleep continuity, sleep architecture and rapid eye movement (REM) sleep patterns were comparable among the four groups. African-Americans had evidence of more stages 1 and 2 and diminished stage 4 sleep, whereas the Hispanics had higher REM density. These preliminary findings suggest that sleep patterns are remarkably similar across cultures. There are, however, important cross-ethnic differences, specifically in the depth of sleep and in phasic REM measures. Because sleep disturbances are common symptoms of emotional disorders and since many psychoactive agents affect sleep, cross-ethnic differences in sleep patterns may have potential implications for the treatment and prevention of psychiatric disorders.
