Only a few European population-based studies on the epidemiology of posttraumatic stress disorder (PTSD) are available to date. This study aims to broaden the epidemiological knowledge of traumatic experiences (TEs), PTSD, and comorbid mental conditions in a representative German sample (N = 2510). The Composite International Diagnostic Interview list of traumatic events, the Posttraumatic Diagnostic Scale, and Patient Health Questionnaire (PHQ)-9 as well as PHQ-15 were used in this survey. Main results were low frequencies of TEs (24%) and PTSD (2.9%). Older participants (>60 years) reported significantly more TEs and more posttraumatic symptoms, whereas there was no significant difference in PTSD prevalence. A third of the subjects diagnosed with PTSD were found positive for depressive syndromes, and 27% were found positive for somatization syndrome. The results show that TEs and posttraumatic symptoms are frequent in senior citizens and thus have to be considered when treating older patients with mental health conditions.

Anliegen Das Auftreten psychischer Erkrankungen bei Migranten und Nichtmigranten soll verglichen werden. Material und Methode In einer repräsentativen Bevölkerungsstichprobe (n = 2510) wurden Prävalenzen mittels PHQ (depressive Störungen, somatoforme Beschwerden, generalisierte Angststörungen) sowie mit der PTDS (Posttraumatische Belastungsstörungen) geschätzt. Ergebnisse 11,1 % der Stichprobe sind Migranten. Diese sind gleich häufig von den untersuchten psychischen Störungen betroffen wie Nichtmigranten. Schlussfolgerung Die Ergebnisse stehen in Kontrast zur weitverbreiteten defizitorientierten Sichtweise auf Migranten. Objectives There are few, methodically heterogeneous and unsatisfactory studies about the mental health of immigrants. Commonly, these studies refer to a single group of immigrants and in consequence general statements about the mental health of immigrants are impossible. Methods In a representative population survey in Germany (N = 2 510) depressive and somatoform symptoms were screened with the Patients Health Questionnaire, Post Traumatic Stress Disorder was screened with the PTDS. If at least one parent was born abroad, people are classified as immigrants. Results 11.1 % of the sample are immigrants, which are mostly better integrated ones. There are no significant differences in the prevalence of the investigated mental disorders of immigrants compared to the native population. Conclusion The sample includes a large variety of immigrants living in Germany and does not refer to a single group. Asylum seekers and undocumented migrants are not included, those immigrants with low language skills might be underrepresented because of the methodology. Against our expectations, no differences in the mental health between imigrants and native Germans could be proven. This finding stands in a marked contrast to the well established deficit-oriented point of view on the health of immigrants.

Many studies have investigated the highly relevant association between pain and disability in clinical groups using the Pain Disability Index (PDI). To interpret these results, knowledge of disability in the general population is crucial. Moreover, to investigate criterion validity of the PDI, the influence on health care utilisation (HCU) is of special interest. In the present study, a broadened version of the PDI was psychometrically evaluated with a large representative sample of the general population. The independent impact of disability on HCU was also investigated. A representative sample of the German general population (N=2510) was screened for disability, somatic complaints, mental health (PHQ) and HCU. Following a psychometric evaluation of the PDI, data are provided about the distribution of disability in the general population. For the prediction of HCU, stepwise linear regression analysis was calculated. The psychometric evaluation of the PDI revealed a one-factor solution, high reliability, and satisfactory construct validity. Percentage scores for the distribution of disability are provided for those people reporting at least one pain/somatic symptom. These data allow a better description of disability in clinical samples. Somatic complaints, disability, unemployment or retirement, depression and anxiety explained 26% of the variance for HCU. The PDI is an economical, reliable and valid self-rating instrument for assessing disability caused by physical symptoms. HCU in the general population is determined by the number and severity of somatic complaints and also by disability. Symptoms and disability play a crucial but somewhat independent role.
