title: [Characteristics of Hospitalized Mentally ill Spanish Migrants in Germany - Results of a Statistical Reanalysis].
abstract: OBJECTIVE
  To draft a clinical profile of mentally ill first-generation Spanish immigrants in Germany treated in a special setting in their native language and to identify possible correlations between time of onset of a mental disorder and migration and also between degree of utilization and clinical as well as care variables.
  
  
  METHODS
  Statistical reanalysis of individual data (n = 100) of a previously published descriptive study with aggregated data corresponding to 15 variables. Correlations are calculated using chi-square as well as Fisher's exact test. Multivariate regression and logistic models were conducted. In addition to the explained variance of the models (R(2)), analyses of residuals as well as post-hoc power analyses (1-β) were performed.
  
  
  RESULTS
  A quarter of the sample (26 %) was mentally ill before migration; most of the patients received treatment very late (about 10 years after onset) and became chronically ill. Half of the sample shows a relevant somatic comorbidity and large average lengths of inpatient stays (54 days). In 16 % of treated cases, repatriation had to be organized. The degree of chronicity correlates with mental illness prior to migration. Severe mood disorders and psychoses occur late after having migrated, addictions and neurotic disorders are equally distributed over time.
  
  
  CONCLUSIONS
  Migration can not be set in a causal relationship with the development of mental disorders, although there is a positive correlation between affective disorders and the duration of the migration status. Chronicity is related to an outbreak of the disease before migration. The sample is relatively homogeneous (one nationality, first generation), but loses epidemiological representativeness (not related to a catchment area).
