These findings support the notion that mental ill health among immigrants is a multi-faceted phenomenon that needs to be tackled within a wide range of sectors - e.g. the healthcare system, the social service sector and, of course, the political arena.

The symptomatic syndrome of probable PTSD does not appear in the absence of extreme trauma, lending empirical support to the definition of PTSD. Prevalence increases with multiplicity of traumas, including those involving a relative or close friend. The high prevalence of probable PTSD found in this study warrants screening for trauma among patients, their relatives and close friends, in outpatient psychiatry.

A high proportion of PTSD and poorer outcome for PTSD patients compared to other psychiatric patients warrants a primary focus upon PTSD in outpatient psychiatry.

Although psychiatric diagnoses are influenced by cultural and social conditions, with large global variations, the ICD and DSM systems are applied worldwide. The aims of this study were to describe the distribution of different ethnic patient groups in psychiatric outpatient services and the influence of ethnicity, demographic conditions and social strain on psychiatric diagnoses. An entire year's cohort of psychiatric outpatients (n = 839) in an outpatient register was divided into nine groups, according to country of birth. The proportion of each group in the outpatient population was compared with its corresponding proportion in the catchment area. In order to examine the relationship between socio-demographic variables and strain on the one hand, and DSM-III-R diagnoses on the other, stepwise logistic regression analyses were carried out. Swedes were the only group under-represented as outpatients (P < 0.001). Africans ran a higher risk (OR = 5.55, 95% CI = 2.56-12.04) than other ethnic groups of receiving a diagnosis of psychotic disorder--except schizophrenia--and Greek patients were more likely to receive a diagnosis of somatoform disorder (OR = 8.81, 95% CI = 4.41-17.59). Swedes were twice as likely to receive a diagnosis of personality disorder (OR = 2.16, 95% CI = 1.55-3.15). Schizophrenia was related to male gender (OR = 1.75, 95% CI = 1.04-2.94) and affective disorders to age >40 years (OR = 1.71, 95% CI = 1.22-2.40). Ethnicity has a strong impact on how diagnoses are given in cross-cultural settings. We could not confirm earlier findings of under-representation of ethnic minorities in outpatient services.

Establishing post-traumatic stress disorder as a psychiatric diagnosis has only marginally increased awareness of traumatic experiences. Traumas are inconsistently recorded in initial psychiatric histories and, when observed, rarely reflected in the primary diagnosis and treatment. The present study aimed to investigate if there is an association between sufficiently addressing trauma and long-term outcome and what factors affect whether trauma, according to the patient's view, is sufficiently addressed or not. Socio-demographic data, experiences of trauma and treatment, and outcome, were collected retrospectively from Arabic, Iranian, Turkish and Swedish patients, who had visited a psychiatric clinic 3-4 years earlier. Fifty-one patients whose traumatic experiences had been sufficiently addressed were compared with 39 patients who perceived that their traumas had not been addressed. Logistic regression analyses were performed to examine relationships between clinical variables and whether or not traumas had been addressed. Patients with trauma sufficiently addressed reported high confidence in staff (odds ratio, OR=7.2, p<0.001), high self-rated health (OR=8.0, p<0.01) and low scores on the Self-rating Inventory for PTSD (OR=7.7, p<0.05) and Depression Scale (OR=3.0, p<0.15). Reporting less than five different traumas (OR=4.6, p<0.01) and being an ethnic Swede (OR=2.4, p<0.10) were the background variables independently related to having trauma sufficiently addressed. Addressing trauma may improve patients' confidence in staff, self-rated health and trauma-related symptoms. Multiplicity of traumas and belonging to an ethnic minority implied that trauma was less addressed.
