During last 40 years there are constant increase of depressive disorders in the population of many countries. Incidence of these disorders got the character of “big epidemy” and became one of the global problem for the world community. Psychogenic stressful factors, experienced by nearly every adult, have a principal role in development of these disorders. At the same time we have a tendency of forming lingering depressions, this fact shows us the urgency of study next important formation factors of lingering affective disorders - clinical factors, type of personality. The purpose of this investigation is a study of clinicopsychopathologic, typological features of patients with lingering non psychotic depression. The methods of this investigation include clinical method, personal inquirer of Leonhard, Lazarus’ indicator of coping-strategies. Patients with acute form of somatic disease and disorders of other registers didn't take part in investigation. Evaluation of clinical syndroms of depression had displayed significant prevalence of astheno-adynamic, anxious and hypochondriacal depression. Most of the patients had a psychologic traumatic experience of interpersonal family relations. Analysis of individual typological features of personality had shown the prevalence of hysteroid and anxiously-sensitive accents of character. It had been discovered significant correlation between the type of personality and preferred coping-strategies in behaviour, realised as “looking-for social support”, “flight- avoidance” and “ranging”. Formation of lingering non psychotic depression is a multiple-factor mechanism. The components of this mechanism may be as clinical syndromic features so as definite type of personality with its coping-strategies and external factor of psychogenic nature.
