Somatic symptoms in Turkish and German depressed patients

Psychiatry in Turkey

The Republic of Turkey has a population of 67.4 million (year 2000) and covers 783 563 km2; administratively it is divided into 81 provinces. A few national statistics from 2000 are: infant death rate 41.9/1000; life expectancy at birth 68 years; unemployment rate 6.6%; gross national product (GNP) per capita US$2965; and adult literacy rate 87.32% (females 80.64%; males 93.86%) (State Statistics Institute, 2003).

Cultural differences in symptom representation for depression and somatization measured by the PHQ between Vietnamese and German psychiatric outpatients

OBJECTIVE

Despite an extensive body of research on somatic symptom presentation among people of East- and Southeast-Asian descent, results are still inconclusive. Examining and comparing symptom presentation in clinically and ethnically well-characterized populations may constitute a step towards understanding symptom presentation between patients with a different cultural background. This study aims to compare Vietnamese and German patients regarding cultural dynamics of symptom presentation upon first admission to a psychiatric outpatient service.

METHODS

110 Vietnamese and 109 German patients seeking psychiatric treatment at two outpatient clinics completed the Patient Health Questionnaire (PHQ). The somatic symptom subscale (PHQ-15), the depression subscale (PHQ-9) and PHQ-subscales examining anxiety and psychosocial stress levels were analyzed and compared for both groups using multivariate analysis of covariance. Regression analysis was utilized to examine the influences of sociodemographic and migration specific factors.

RESULTS

Vietnamese and German patients showed comparable Cronbach's alpha for all subscales. Vietnamese patients endorsed significantly higher levels of somatic symptoms overall and on certain items (as pain-related items, dizziness, and fainting spells) despite similar levels of depression severity in comparison with German patients. Vietnamese patients with poor German language skills showed a significantly higher focus on somatic symptoms.

CONCLUSION

Raising awareness for cultural dynamics of symptom presentation in patients with depression is indispensable. Cross-cultural symptom assessment using the PHQ seems feasible and expands our understanding of depressive and psychosomatic symptoms when assessed by clinicians.

Comprehensive Psychopathological Assessment Based on the Association for Methodology and Documentation in Psychiatry (AMDP) System: Development, Methodological Foundation, Application in Clinical Routine, and Research

The documentation of psychopathology is core to the clinical practice of the psychiatrist and clinical psychologist. However, both in initial as well as further training and specialization in their fields, this particular aspect of their work receives scanty attention only. Yet, for the past 50 years, the Association for Methodology and Documentation in Psychiatry (AMDP) System has been in existence and available as a tool to serve precisely the purpose of offering a systematic introduction to the terminology and documentation of psychopathology. The motivation for its development was based on the need for an assessment procedure for the reliable documentation of the effectiveness of newly developed psychopharmacological substances. Subsequently, the AMDP-System began to be applied in the context of investigations into a number of methodological issues in psychiatry (e.g., the frequency and specificity of particular symptoms, the comparison of rating scales). The System then became increasingly important also in clinical practice and, today, represents the most used instrument for the documentation of psychopathology in the German-speaking countries of Europe. This paper intends to offer an overview of the AMDP-System, its origins, design, and functionality. After an initial account of the history and development of the AMDP-System, the discussion will in turn focus on the System's underlying methodological principles, the transfer of clinical skills and competencies in its practical application, and its use in research and clinical practice. Finally, potential future areas of development in relation to the AMDP-System are explored.

Understanding psychopathology in migrants: a mixed categorical-dimensional approach

BACKGROUND

Literature on mental disorders in migrants is constantly increasing. Only a few studies describe psychopathological dimensions in migrants over their nosographic diagnoses; however, there is a growing literature about the greater utility of a categorical-dimensional approach, rather than a solely categorical approach, in the understanding of mental disorders. The aim of this paper is to describe the phenomenology of mental disorders in migrants referred to the Transcultural Psychiatric Team of Bologna (BoTPT), by analysing the psychopathological dimensions that underlie their clinical diagnoses.

METHODS

We recruited all migrants who attended the BoTPT between May 1999 and July 2009. The psychopathological assessment was conducted with the Association for Methodology and Documentation in Psychiatry (AMDP) and clinical diagnoses were formulated according to ICD-10. We proceeded through a two-step analysis: (1) comparing the prevalence rates of psychopathological symptoms across diagnoses; then (2) conducting a factor analysis to assess how those symptoms configure psychopathological dimensions and how these dimensions underlie clinical diagnoses.

RESULTS

As expected, we found significant associations between diagnoses and the prevalence of their core psychopathological symptoms. Factor analysis revealed a strong polymorphism of the psychopathological presentation of mental disorders and unexpectedly showed that in each diagnostic cluster, the first extracted factor was not composed of core symptoms.

CONCLUSIONS

A mixed categorical-dimensional approach seems to improve the description of the psychopathology among migrants, as it adds relevant information regarding psychopathological dimensions useful to the understanding of the peculiar clinical expressivity of our patients.

The influence of stigma on depression, overall psychological distress, and somatization among female Turkish migrants

BACKGROUND

Even though some studies suggest that in Mediterranean and non-western cultures more somatic and less psychological symptoms are reported, this so-called 'somatization' hypothesis has been challenged. Reviews show that somatic symptoms are a core component of depressive episodes regardless of cultural background. The expression of symptoms might be related to the psychosocial, social and cultural context surrounding the patient rather than 'ethnicity' or related constructs. Also, stigma associated with mental disorders can affect patients'symptom presentation.

METHODS

The interrelationships of perceived stigmatization (Explanatory Model Interview Catalogue - Stigma Scale), depression (Beck Depression Index II), overall psychological distress (Symptom Checklist-90-R), and somatic symptoms (The screening for SOMATOFORM SYMPTOMS II) was assessed in a sample of female patients with Turkish descent with a diagnosis of depression (N=63).

RESULTS

Depression, overall psychological distress, and somatic symptoms were positively and significantly related. Stigma was positively related to depression and overall psychological distress. There was no significant relationship between stigma and somatic symptoms, neither among the severely depressed group (N=39), nor among the less depressed group (N=24).

CONCLUSION

The positive relationships between stigma, depression, and overall psychological distress indicate that patients who are more depressed and who have higher levels of overall psychological distress experience their condition as more stigmatizing. Since somatic symptoms and stigma were not related (neither positively, nor negatively), it appears that depressive symptoms and other symptoms of psychological distress affect concerns about stigmatizing attitudes in a way that somatic symptoms do not. This result challenges common assumption of the 'somatization'hypothesis, i.e. that depression is 'somatized'because of concern about stigmatizing attitudes.

Ethnic and migrational impact on the clinical manifestation of depression

PURPOSE

Depressive disorders are still underdiagnosed. Ethnic and cultural factors may influence the way depression is presented and therefore contribute to problems in assessing these disorders in different ethnic populations appropriately. In this investigation, the impact of both ethnicity and migration on the manifestation of depression was studied.

METHODS

Three groups of depressed female patients (n = 136) were included in this investigation on the variation in depressive symptomatology by ethnic groups. Group 1 consisted of Austrian patients living in Austria, group 2 were Turkish patients who had migrated to Austria and group 3 were Turkish patients living in Turkey. Participants were rated using the Montgomery-Åsberg Depression Rating Scale (MADRS), the Beck Depression Inventory (BDI), the Bradford Somatic Inventory (BSI) and an additional list of physical symptoms.

RESULTS

Both Turkish groups had significantly higher BSI scores and more somatic symptom severity. Migrated Turkish patients scored significantly higher in the items headache, backache and dry mouth than Turkish patients in Turkey. In addition, there were between-group differences in non-physical symptoms.

CONCLUSIONS

Depressive symptomatology varies between ethnic groups. These differences are mainly due to ethnicity as such but migration may play an additional role. It is essential for physicians to be aware of atypical presentation forms of depression in minority groups.

Somatic complaint differences between Turkish immigrants and Belgians: do all roads lead to Rome?

OBJECTIVE

Turkish immigrants have been found to report more somatic complaints compared to western majority groups. The present study investigates the combination of two cultural explanations (somatization versus psychologization and emotion mediation) with two acculturative explanations (acculturative stress versus acculturative transition) to explain these differences.

DESIGN

In total, 144 Turkish immigrants, 353 Belgian majority members, and 222 Turkish majority members were asked to report the last three emotional episodes they encountered and to rate them on 24 emotion terms and 17 somatic sensations.

RESULTS

Turkish majorities scored higher on all somatic factors, anxiety-sadness, and self-conscious emotions followed by Turkish immigrants and Belgian majorities. Furthermore, path analysis showed (partial) mediation effects of anxiety-sadness and self-conscious factors on the differences in the somatic factors between Belgian and Turkish majorities.

CONCLUSION

These results indicate that the somatic differences do not result from a trade-off between somatization and psychologization, but that emotions mediate differences in somatic processes to a large extent. It was also found that differences between Turkish immigrants and Belgian majority members are to be attributed to acculturative transition, rather than to acculturative stress.

Somatic and Emotional Well-Being Among Turkish Immigrants in Belgium: Acculturation or Culture?

The present studies investigate differences in well-being between Turkish immigrants, Belgian majority members, and Turkish majority members. Furthermore, the relationships between two acculturation dimensions (adaptation and maintenance) and well-being is investigated within the immigrant group. In a first study, somatic well-being is studied in a sample of 519 Belgian majority members, 229 Turkish immigrants, and 232 Turkish majority members. Turkish immigrants reported the most somatic complaints, followed by Turkish majorities and Belgian majorities. No relationships with acculturation were found. In a second study, emotional well-being (sadness/anxiety, anger, and positive emotions) was investigated in 519 Belgians, 151 Turkish immigrants, and 200 Turkish majority members. No differences were found for sadness/anxiety. Turkish majority members report less anger than the other two groups. For positive emotions, Turkish majority members score the lowest, followed by the Turkish immigrant group and the Belgian majority members. In the immigrant group only adaptation was associated with more positive emotions. Both studies demonstrate that indices of well-being behave differently in cross-cultural comparative research.

Stationäre psychosomatische Rehabilitationsbehandlung von Patienten mit türkischem Migrationshintergrund

Die Behandlung von Patienten mit Migrationshintergrund gewinnt im Kontext psychosomatischer Rehabilitation zunehmend an Bedeutung. Dabei stellt die Gruppe der türkischstämmigen Personen die größte Migrantengruppe dar. Erste Befunde weisen den Faktor Migrationshintergrund als negativen Prädiktor des Behandlungserfolges aus, die spezifischen Hemm- und Förderfaktoren dieser Patientengruppe sind jedoch nur unzureichend untersucht. Der vorliegende Beitrag klärt anhand einer Stichprobe von 521 Patienten einer psychosomatischen Rehabilitationseinrichtung, ob sich deutsch- und türkischstämmige Patienten in Bezug auf Ausgangsvoraussetzungen sowie Behandlungserwartungen und -erfolg unterscheiden. Hierbei zeigt sich, dass die türkische Migrantengruppe nicht nur schlechtere Behandlungsergebnisse aufweist als die deutsche Kontrollgruppe, sondern sich auch in den Störungsbildern und nahezu allen Ausgangsbedingungen unterscheidet (z. B. bildungs- und erwerbsbezogenen Angaben, den Lebensformen und Rentenbestrebungen).

Beck Depression Inventory II: evaluation of the psychometric properties and cut-off points in a Turkish adult population

Numerous studies have been previously conducted to assess the Beck Depression Inventory-II's [BDI II; Beck et al., 1996] psychometric properties. However, none of these studies has examined whether the original cut-off scores were applicable to other cultures. Thus, in addition to evaluating its psychometric properties, we also determined the cut-off scores of the BDI II for the Turkish population. Data from nonclinical (n = 362) and clinical psychiatric outpatients diagnosed as depressive disorder according to DSM-IV criteria (n = 176) were gathered. Analyses for internal consistency and test-retest reliabilities and for convergent and discriminant validities were computed. Two confirmatory factor analyses, one derived from the present exploratory factor analyses and the other proposed in the original study were conducted for both groups. A receiver operating characteristics curve was utilized to determine the cut-off scores for the Turkish population revealing 0-12 for minimal, 13-18 for mild, 19-28 for moderate and 29-63 for severe depression. The internal consistency for the nonclinical and clinical groups were .90 and .89, respectively; test-retest stability was also high (r = .94). Convergent and discriminant validity results were satisfactory. Findings confirmed the present model for the clinical group and equally confirmed both models for the nonclinical group. Furthermore, the cut-off scores to classify minimal, mild, moderate, and severe depression were quite akin to the cut-off points previously suggested for the American population. Taken as a whole our findings revealed that BDI II has sound psychometric properties and comparable cut-off scores for the Turkish population.

Depressive Störungen

Das Spektrum depressiver Erkrankungen macht den Hauptteil affektiver Störungen aus und gehört mit einer Inzidenz von ca. 8–20% zu den häufigsten psychischen Erkrankungen. Depressionen werden nach wie vor zu selten einer adäquaten Therapie (Antidepressiva, störungsspezifische Psychotherapie wie z. B. kognitive Verhaltenstherapie) zugeführt.

Self-reported anxiety, sleeping problems and pain among Turkish-born immigrants in Sweden

OBJECTIVES

To study whether symptoms of self-reported anxiety, sleeping problems and severe pain are more common among Turkish-born immigrants in Sweden than among Swedes, and whether age and socio-economic status can explain this hypothesised difference.

DESIGN

Two random samples were studied -- the Swedish National Board of Health and Welfare Immigrant Survey, and the Swedish Annual Level-of-Living Survey, both from 1996. A total of 526 Turkish-born immigrants in Sweden were compared with 2,854 Swedish controls, all aged between 27 and 60 years. Data were analysed by sex, in an age-adjusted model; and a full model also included age, education, marital status, employment and country of origin (logistic regression).

RESULTS

In the full model, odds ratios were 2.12 (1.43-3.15) for anxiety, 2.60 (1.82-3.72) for sleeping problems, and 2.14 (1.50-3.05) for severe pain among Turkish-born men, and 2.44 (1.69-3.53) for anxiety, 3.01 (2.09-4.33) for sleeping problems, and 2.59 (1.80-3.71) for severe pain among Turkish-born women, using the Swedish controls as references.

CONCLUSIONS

Being a Turkish-born immigrant in Sweden significantly increases the risks for self-reported anxiety, sleeping problems and severe pain, even after adjusting for age and socio-economic status (education, marital status and employment).

Racial/ethnic differences in adolescents' physical symptoms

This study was conducted to establish race/ethnic-specific prevalence for 10 physical symptoms in American youths and to examine the extent to which socioeconomic status and depressive symptoms explained racial differences in those symptoms. This descriptive study was based on a cross-sectional analysis of survey data from Wave I of the National Longitudinal Study of Adolescent Health including a school-based sample of over 20,000 adolescents in Grades 7 through 12. Self-reported physical symptoms during the past 12 months were examined. White youths reported the highest frequency of headaches, musculoskeletal pain, and dizziness; feeling hot, chest pain, cold sweats, and urinary symptoms were more common in Black youths. The three symptoms reported by Whites remained significant after controlling for family income and depressive symptoms, whereas racial differences in the four symptoms prominent in Blacks were accounted for by family income and depressive symptoms. Findings highlight racial differences in symptom types and in psychosocial factors contributing to physical symptoms in adolescents and warn against health-care providers' stereotyping associations between physical symptoms and socioeconomic status.
