According to WHO, depression is one of the most common mental disorders on the planet that has a direct impact on a person's loss of ability to work and is the second most frequent cause of suicide. In European countries, postpartum depression occurs at a frequency of 10-15%, while in Muslim countries the figure is 17-27%. Unfortunately, Russia does not register statistically the number of cases where women consult specialists about their symptoms of postpartum depression. If we accept the WHO overall data, about 200 thousand women in Russia had postnatal depression (PND) in 2017 alone. The problem of measuring the level of PND in Russia is acute. The important goal of the study is to design a methodological toolkit for assessing a woman's psychological state in order to prevent the occurrence of depression. This task includes the adaptation of the Edinburgh Postnatal Depression Scale (EPND) -a methodology intended for PND diagnosis, which is successfully used in many countries for about 20 years. 151 mothers of children from 1 to 11 months (mean age = 5,4 months) took part in the study. EPND scale was translated in Russian and showed high validity (α = ,838) and strong correlations with Beck Depression Scale (r-Spearman = ,798, p < 0.01). .
