[Effect of psychiatric service resources on detection of mentally ill patients in Siberia and Far East (correlation-regression analysis)]. / Vliianie resursov psikhiatricheskoi sluzhby na vyiavlenie psikhicheski bol'nykh v regionakh Sibiri i Dal'nego Vostoka (korreliatsionno-regressivnyi analiz).

Analysis of the character of the linear relation between the totality and some factors (the number of beds, psychiatrists working at hospitals and on an outpatient basis) that characterize the psychiatric services in 18 regions of Siberia and the Far East over 16 years as well as between the identification of new cases of schizophrenia, epilepsy, alcoholism, neuroses, psychoses and oligophrenia has demonstrated a high efficacy of the totality of factors. The differences have been shown between the regions in respect to the relation of the factors to the disease incidence, explained by the authors by the specificity of the organizational structure of the psychiatric services and by a number of other factors.

[Isolation of informative factors regarding the development of epilepsy by the method of image recognition]. / Vydelenie informativnoi sovokupnosti vozniknoveniia épilepsii metodom raspoznavaniia obrazov.

A complex of factors carrying major information on the epileptogenesis was recognized and their interrelation analyzed. Initial sample comprised 14 signs of the patients' constitutional features (532 individuals) and their relatives' mental health (10858 individuals). A model was constructed to represent the interrelation of the signs using an algorithm of logical-+-mathematical image detection realized on an SM-4 computer. Eight signs were entered into a most informative group. The model helped to formulate new theoretical notions of the relationship of constitutional and hereditary factors in epileptogenesis.

[Correlation-regression analysis of the influence of psychiatric service resources on the dynamics of detected morbidity in the populations of Siberia and the Far East]. / Korreliatsionno-regressionnyi analiz vliianiia resursov psikhiatricheskoi sluzhby na dinamiku vyiavlennoi boleznennosti naseleniia Sibiri i Dal'nego Vostoka.

The authors have demonstrated the existence of linear correlation between the complex of three factors (the number of beds and psychiatrists in hospitals and outpatient clinics) and incidence rate (over a period of 16 years) of neuroses in 11 administrative areas, epilepsy, in 12 areas, psychoses, in 15, oligophrenia, in 17, alcoholism and schizophrenia in all 18 areas of Siberia and the Far East. Correlations of each of the three factors with the morbidity rate varied within a wide range in relation to both administrative areas and individual diseases. The authors draw attention to the importance of supplementing the growth of resources of psychiatric service with new forms and methods of work.

[Multidimensional analysis of the relation between the resources of the psychiatric service and the detection and prevalence of mental patients in regions of Siberia and the Far East]. / Mnogomernyi analiz sviazi resorsov psikhiatricheskoi sluzhby s vyiavleniem i rasprostranennost'iu psikhicheski bol'nykh v regionakh Sibiri i Dal'nego Vostoka.

The article deals with the assessment of the main components and canonic correlations reflecting the relationship between the resources of psychiatric care (a number of beds and psychiatrists providing medical care in hospitals and in other settings) and the rate of identification and incidence of psychoses, schizophrenia, epilepsy, alcoholism, neuroses and oligophrenia in Siberia and Far East over a period of 16 years (from 1965 to 1981 excluding 1978). The first main component covered up to 80.1% of the dispersion range of the identification rate and 94.5% of the incidence rate, the second component covered up to 37.1% and 21% respectively. Canonic correlations proved higher for the incidence rate as against the identification rate. Although there were substantial differences in the studied interrelationship with regard to a number of territories, the main tendency was expressed in a marked linear correlation between a growth in the resources of psychiatric service and the time-course of the rates of the studied pathology.

[Extraction of an informative cluster of factors for identification of patients with neuropsychiatric diseases]. / Vydelenie informativnoi sovokupnosti faktorov dlia raspoznavaniia bol'nykh nervno-psikhicheskimi zabolevaniiami.

On the basis of a blanket examination of employees at a large industrial enterprise which revealed 743 patients with neuropsychic diseases, predominantly of a borderline nature, and of 273 mentally normal subjects the authors, using the algorithm of image recognition identified an informative aggregation of factors determining the status of mental health. In the total sample the authors received 85.5% of correct, 13.8% of erroneous, and 0.7% of unrecognized solutions. The authors also discuss signs considered as risk factors and as factors of resistance in relation to the development of neuropsychic abnormalities. The utilization of the results obtained may be promising in conducting the preliminary automatic screening of the population with the purpose of identifying groups at a risk of developing neuropsychic disturbances.
