Studied are changes in diagnosis in a random sample of 10% of all first admissions to psychiatric hospitals and psychiatric wards of general hospitals in Israel from 1983 to 1990 with follow-up evaluation to 1991. This included 4,570 hospitalizations of 2,220 patients. Data were extracted from the National Psychiatric Case Registry of the Ministry of Health. Almost 59% of the sample had one admission, 18% had two, 9% had three, and 14% had four or more. From the first admission to the last discharge (a mean of 2.15 years), 59.2% of the patients' diagnoses did not change. In 89.46% of the cases in which the diagnosis changed, the changes took place during the first admission. Diagnostic change differed between diagnostic groups. In descending order of stability in diagnosis from the first admission to the last discharge were neurotic and personality disorder (73.6%), mental retardation (73.5%), schizophrenia (73.0%), organic conditions (70.6%), affective disorders (66.2%), substance abuse (65.6%), childhood disorders (60%), paranoid disorder (43.6%), other nonorganic psychosis (30.3%), and V-codes (25.0%). The average level of diagnostic agreement between the first admission and the last discharge was a kappa of .52. The average length of stay for patients whose diagnosis became more severe was considerably longer than for patients whose diagnosis became less severe or did not change in level of severity. Older age was related to less change in diagnosis. For patients aged less than 18 years, diagnosis changed in 46.7% of the cases, for patients aged 19 to 44, 31.2%, and for patients older than 45, 27.8%.

Relatedness of schizotypal personality to schizophrenic disorders: multifactorial threshold model.

Genetic analysis of schizophrenia and schizotypal personality disorder (SPD) was conducted on two pedigree samples. The results are interpreted in terms of a multifactorial threshold (MFT) model. A high rate of schizophrenia was found in relatives of both samples, but any excess of SPD was found only in relatives of the SPD sample. Based on these data, the hypotheses assuming a single liability with two thresholds (Reich's model) and different liability (Smith's model) for both disorders were rejected. The coefficient of genetic correlation is 0.61. Our data suggest that schizophrenia and SPD are separate nosological entities and that some of the factors which constitute liability to SPD influence the development of schizophrenia, but not vice versa.

Effects of immigration on the mentally ill--does it produce psychological distress?

This report explores psychological distress among immigrants seeking help from psychiatric outpatient clinics as compared with control nonpatient immigrants. Our hypothesis is that nonpsychotic mentally ill immigrants will react to acculturation by psychological distress similarly to healthy individuals. Three questionnaires were used in this survey: Demographic Psychosocial Inventory, Brief Symptom Inventory (BSI), and Psychiatric Epidemiology Research Interview-Demoralization Scale (PERI-D). They were completed by patient and control groups consisting of recent adult immigrants to Israel from the former Soviet Union. The patient group included 158 subjects seeking psychiatric help from outpatient clinics. Among them, 51 met ICD-10 criteria for neurotic, stress-related, and somatoform disorders; 41 for schizophrenia; 32 for mood disorders; 18 for organic illnesses; and 16 for personality disorders. The control group consisted of 222 immigrants with no previous psychiatric history, matched by gender and age to the patient group. Although all distress symptoms were significantly more severe in the patient group than in the control group, the BSI profile, showing a high level of depression, anxiety, interpersonal sensitivity, and obsessive-compulsive dimensions, was similar in both groups. The psychological distress level as measured by the PERI-D was 1.4 times higher in patients than in the control group. Within the patient group, the lowest distress level was found in patients suffering from organic disorders. No significant differences in the level of psychological distress were found among other diagnostic subgroups. The results suggest that mentally ill immigrants react to acculturation by a psychological distress syndrome similarly to nonpatient immigrants but more severely than nonpatient immigrants.
