The use of recent life change measurement in the lives of persons developing mental disorders parallels the measurement of risk factors by epidemiologists to understand disease distribution. Examples are given of these parallels, along with critical commentary on methodological issues in life changes research. The principal studies documenting the association of recent life change and depression, schizophrenia, and neurosis are reviewed. Recent life changes appear to be an important element in explaining illness onset. Future advances in the area of life change and illness await the development of reliable and valid measures of an individual's stress tolerance characteristics, such as social support systems, psychological defenses, coping capabilities, and illness behavior tendencies.

In an attempt to demonstrate a valid boundary between schizophrenia and the affective psychoses, discriminant function analyses have been carried out with history, mental state and follow-up data in two populations of patients. A bimodal distribution of discriminant scores was obtained in one of them (a general psychotic sample of 128 patients), using a discriminant function derived from the same sample; but when the function was applied to the second population (a schizoaffective sample of 106 patients) the distribution was ambiguous. Functions derived from the schizoaffective sample produced highly skewed distributions of discriminant scores in the general psychotic sample. Kraepelin's hypothesis that the functional psychoses consist of two distinct disease entities receives some support from our findings, but there is still no compelling evidence that the universe of psychotic patients falls naturally into these two groups.

A special statistic method of confrontation of diseases with aggravation hereditary in the group "parents - children" is proposed. This method can be used under clinical formalization of the diseases. It is shown on a model group parents - children (118 pairs) suffering with schizophrenia, that statistical confrontation makes possible to work out group and individual prognoses in the descending generation. It is found that invariability in the descending generation is provided by a small number of stable indices, other symptoms being variable. Statistic description of the disease symptoms in the descending generation is of interest for planning genetic interpretation.

This study tested the hypothesis that schizophrenics employ more developmentally immature levels of decentering in their structuring of interpersonal relations. A 9-point scale of interpersonal decentering, developed originally by Feffer, was applied to Thematic Appercetion Test stories produced by schizophrenic adolescents and a control group of psychiatrically disturbed patients equivalent in age and intellectual functioning. Results provided convincing support for the hypothesis tested and suggest the theoretical utility of viewing interpersonal deficit in schizophrenia from a cognitive-developmental perspective.

Patients over 15 years of age from Turku hospitalized for psychosis for the first time during the years 1949-50, 1959-60 or 1969-70 were investigated. The incidence of hospitalized psychoses (per 100,000 inhabitants) was 115, 136 and 160, respectively. The increase in incidence was greater in women than in men. The incidence remained approximately the same in patients aged 30 to 59, but increased in the younger and older groups. The incidence of functional psychoses increased; in schizophrenia, however, it declined, while in paranoid and effective psychoses it increased. In organic psychoses, the admission frequency of psychoses of old age rose in the 1950's, but declined in some measure in the 1960's. The incidence of psychosis increased for single persons. The ratio of the incidence between single and married persons rose in men, whereas in women it fell. This was particularly pronounced in schizophrenics. The incidence of psychosis was highest in unskilled laborers. The overrepresentation of schizophrenia and paranoid psychoses seemed to have become more pronounced in this occupational group.

Patients suffering from acute schizophrenia are subjected to treatment according to different therapy standards, depending on the individual hospital. Hence, the present study aimed at a comparative investigation of the effects and side effects of fluphenazine dihydrochloride administered to 51 acutely diseased schizophrenics via the intravenous, intramuscular and oral routes. It was also interesting to record the assessment of efficacy, painfulness and, as the case may be, repeated selection of the form of application concerned, by the patients themselves. Finally, we also investigated the relations between the age of the patients, duration of previous hospitalisation, and the effects achieved with the three application forms. Documentation was effected via the following examination instruments described and recommended by the National Institute of Mental Health (NIMH), USA; CGI, BPRS, Dotes, APDI and PTR.

The study reports about the intravenous application of Biperiden at patients with acute hypokinetic reaction suffering from schizophrenia of the paranoid-hallucinatory type. In all of the six cases examined a fast abolition of the stupor could be observed. The pathophysiological mechanisms deriving from our clinical experiences are discussed. Furthermore, a therapeutic procedure is suggested to treat acute schizophrenic stupor merely with drugs.

The term 'schizophrenic' is used in two distinct ways: namely to describe a particular type of illness and also as a label for the person suffering from this illness. If we concentrate on the 'illness' conception of schizophrenia it readily becomes apparent that its definition and nature varies somewhat from one proponent to another. Added to this is the problem that the major conceptions of schizophrenia are based on disjunctive concepts. The basic argument of this paper is that while all clinical conceptions of schizophrenia have assumed the existence of a disease-entity syndrome, no attempt has ever been made to test its logical alternative: namely a random-symptom model. Some data will be presented which are at least compatible with this alternative and some of the theoretical implications spelt out.

Long-term amphetamine administration to cats (a mean of 8.75 milligrams per kilogram twice daily for 10 days) produced large decreases (40 to 67 percent in serotonin and its major metabolite, 5-hydroxyindoleacetic acid, in all brain regions examined. This treatment also produced several behaviors that are dependent on depressed central serotonergic neurotransmission, and which normally are elicited exclusively by hallucinogenic drugs. Short-term amphetamine administration (15 mg/kg) did not produce these behaviors and resulted in small decreases in brain serotonin and no change in 5-hydroxyindoleacetic acid. These data are discussed in the context of monoamine theories of schizophrenia.

Parents of schizophrenics show more transactional style deviance in diverse situations than do other parents. In a sample of families of nonschizophrenic outpatient adolescents, a manual for scoring such deviance on stories told for seven TAT cards was developed. This scoring system was shown to be composed of six meaningful factors. When this system was applied to the TAT's of parents of offspring with a variety of psychiatric diagnoses, a total deviance score did not discriminate among the parents. High scores on two particular factors were found only in parents of hospitalized schizophrenics, but four factors were nondiscriminating. Parents of young adults with schizophrenia spectrum disorders were more likely to show high scores on at least one of these six factors than other parents. Considering the scores of mothers and fathers together yielded the best discrimination of parents of schizophrenia spectrum disorders from other parents.
