Background. In the modern reality, a person faces many daily troubles, which accumulate and have a negative impact on mental and physical health. In this regard, the relevance of studying the structure of daily stress (DS) is obvious, as it allows to understand the specifics of the relationship between daily stressors depending on the life situation. Understanding the structure of daily stress that occurs in a person's ordinary situation and in a situation of uncertainty is important not only for scientific knowledge, but also for the psychological practice in terms of developing effective coping behavior programs and crisis counseling.

Objective. To study the relationships of various stressors in the structure of DS in everyday life and in a situation of uncertainty (under the influence of a global macrostressor — COVID-19).

Study Participants. The study involved 771 respondents aged 20 to 68 years, including 530 women and 241 men: 407 people before the pandemic period and 364 people during the pandemic period.

Methods. Everyday Stressors Questionnaire (Petrash et al., 2018), comparative analysis, multivariate analysis of variance (MANOVA), structural modeling method "path model".

Results. The study revealed certain differences in the severity of DS characteristics indicating an increase in the intensity of subjective stress experience and a decrease in the level of sensitivity to daily stressors during the pandemic period. The comparative analysis demonstrated gender differences in the intensity of DS experience and the level of sensitivity to everyday stressors. The results of structural modeling identified the specifics in the structure of DS in everyday life (before the pandemic) and in a situation of uncertainty (during the pandemic).

Conclusions. The specificity of the interrelations of stress factors in the structure of daily stress varies depending on the living conditions of a person. In habitual living conditions, the leading stressor is "violation of plans". Under conditions of a macrostressor, a "stress complex" of a situation of uncertainty arises, the triggers being the stressors "expectations", "violation of plans", "affairs/work", associated with the unknown consequences and uncertainty of the future, including employment. The level of stress in the area of family relations in a situation of uncertainty tends to increase in both men and women, but in men this increase is more pronounced. At the same time, women show a more pronounced decrease in the level of sensitivity to daily stressors. In general, under conditions of a macrostressor, the severity of daily stress and its characteristics is higher in women.

Background. Daily work-related stressors, unlike major (life) negative events, are characterized by a lower intensity, however, due to a higher frequency of occurrence, they can lead to mental overstrain and chronic stress. In the modern realities of multitasking the search and study of psychological resources available to a person on a daily basis is of particular importance.

Objective. To study the contribution of a healthy lifestyle and daily positive events to overcoming everyday stress associated with professional activity.

Study Participants. The study involved 155 respondents aged 20 to 56 years (M_age = 31.1; SD = 9.2; 32.3% men, 67.7% women) living in St. Petersburg, Leningrad region and Moscow. The selection method is a random sampling.

Methods. "Profile of a healthy lifestyle" (Petrash, Strizhitskaya, Murtazina, 2018); Questionnaire of everyday stressors (Petrash et al., 2018); authors' questionnaire of everyday positive events; "Scale of perceived stress-10" (Ababkov, 2016), a socio-demographic questionnaire. The results were processed by means of "IBM SPSS Statistics 22", "AMOS" and "Microsoft Excel". Mathematical statistics methods included the descriptive statistics, cluster analysis (k-means), univariate analysis of variance (ANOVA), structural equation modeling (SEM).

Results. The study revealed that respondents with the lowest level of perceived stress are characterized by a greater desire to develop internal resources and achieve self-realization as well as the ability to recognize sources of stress. The analysis allowed to construct a structural model demonstrating the contribution of lifestyle parameters and daily positive events to coping with stress associated with professional activity.

Conclusions. The parameters of lifestyle and daily positive events contribute to reducing the efforts spent by a person on stress management, which leads to reducing overstain and, as a result, a decrease in the subjectively perceived intensity of stressors associated with professional sphere. Professional achievements, interpersonal communication, inner growth, and the ability to recognize sources of stress can serve as resources for coping with stress.
