Purpose : to find out the effect of regular physical exercises and perceived stress interaction on students’ satisfaction with life. Material and methods : The study involved university students (n = 355; М age = 19,97; SD = 2,12). The moderator analysis was conducted according to the cross-sectional questionnaire. Results : It is determined that the difference in students' satisfaction with life at the average and high perceived stress is due to physical exercises. The influence of the interaction of variables (physical activity x perceived stress) on satisfaction with life was statistically significant. Conclusions : It is revealed the peculiarities of interaction between the physical exercises and perceived stress. The reduce of satisfaction with life under the influence of perceived stress is more typical for those students who do not regularly practice physical exercises. Physical exercises act as a buffer against stress.

Purpose of the work was to investigate the mediating role of psychological capital in the relationship between subjective perceptions of stress and person’s life satisfaction.Methods. Psycho-diagnostic methods “Stress Perception Scale-10”, “Psychological Capital”, “Life Satisfaction Scale” were used. Statistical analysis included calculation of descriptive statistics, correlations between variables (r-Pearson), finding differences between samples (ANOVA) and mediator analysis.Results. On the basis of a cross-sectional research of a sample of 460 people, the hypothesis that life satisfaction negatively correlates with the level of subjective perception of stress and positively with psychological capital was confirmed. Subjective perception of stress, in turn, negatively correlates with psychological capital. The hypothesis of the mediating role of psychological capital was partially confirmed, as the relationship between the perception of personal stress and life satisfaction remained statistically significant, although it decreased after psychological capital was added as a mediator. This result indicates that the cognitive assessment of stressors remains an important variable for predicting life satisfaction, even when regulating dispositional characteristics. Psychological capital as an integral personal resource is by a third statistically significant in determining the relationship between person’s perception of stress and life satisfaction. Affecting directly, subjective perception of stress explains 18.9% of the life satisfaction variance; at the same time the model mediated by psychological capital adds another 8.6%.Conclusion. Psychological capital is one of the integral personal resources, which provides a mechanism of response, processing and recovery from stressors, supporting the subjective well-being. It explains a third of the variance of the relationship between subjective perception of stress and life satisfaction. Psychological capital provides a partial mediating effect when people encounter stressors to maintain their well-being.Key words: life satisfaction, subjective well-being, psychological capital, perception of stress, mediator analysis. Метою роботи було вивчення опосередкованої ролі психологічного капіталу у взаємозв’язку між суб’єктивним сприйняттям стресу та задоволеністю життям особистістю.Методи. Використовувались психодіагностичні методики «Шкала сприйняття стресу-10», «Психологічний капітал», «Шкала задоволеності життям». Статистичний аналіз містив розрахунок описових статистик, кореляцій між змінними (r-Пірсона), знаходження відмінностей між вибірками (ANOVA) та медіаторний аналіз.Результати. На основі кроссекційного дослідження вибірки з 460 осіб підтверджено гіпотези, що задоволеність життям негативно корелює з рівнем суб’єктивного сприйняття стресу та позитивно – з психологічним капіталом. Суб’єктивне сприйняття стресу негативно взаємозв’язане з психологічним капіталом. Частково підтвердилась гіпотеза про опосередковану роль психологічного капіталу, оскільки взаємозв’язок між сприйняттям стресу особистістю та задоволеністю життям залишився статистично значущим, хоча і зменшився після того, як був доданий психологічний капітал як медіатор. Цей результат указує на те, що когнітивна оцінка стрес-факторів залишається важливою змінною для прогнозу задоволеності життям, навіть за умов контролю диспозиційної характеристики. Психоло-гічний капітал як інтегральний особистісний ресурс на третину статистично значуще визначає взаємозв’язок між сприйняттям стресу особистістю та задоволеністю життям. Суб’єктивне сприйняття стресу безпосереднім впливом пояснює 18,9% дисперсії задоволеності життям, а модель з опосередкуванням психологічним капіталом додає ще 8,6%.Висновки. Одним з інтегральних особистісних ресурсів, що забезпечує механізм реагування, переробки та відновлення після стресових факторів, підтримуючи суб’єктивне благополуччя, є психологічний капітал. Він пояснює третину дисперсії взаємозв’язку між суб’єктивним сприйняттям стресу та задоволеністю життям. Психологічний капітал забезпечує частковий медіаторний ефект, коли люди зіштовхуються зі стресовими факторами для підтримки свого благополуччя.Ключові слова: задоволеність життям, суб’єктивне благополуччя, психологічний капітал, сприйняття стресу, медіаторний аналіз.

COVID-19 changes radically people’s daily lives, endangering their well-being. Under such conditions, knowledge on psychological characteristics of pandemic situation experiencing and its impact on life satisfaction as a component of an individual’s subjective well-being is of paramount importance for solving the mental health problems during the pandemic situation. The sample consisted of 465 people (160 men, 34.4%; 305 women, 65.6%) aged 18 to 85 years (M = 35.53; SD = 11.64). As a result, two-thirds of the respondents indicated that the pandemic significantly affected their lives. This was a situation with a high stress-cumulating potential. About 65% of the respondents were worried about possible economic losses, 35% had already experienced worsened financial income. The third of the respondents noted that their professional prospects had deteriorated. Most respondents were concerned about the potential risk of virus contracting. Health changes during introduced restrictive measures because of the pandemic were not felt by most respondents. The assessed impact of the coronavirus pandemic on people’s life was related to the respondents’ perceptions of changes in their professional, financial spheres, health and to the anxiety about possible future negative economic and medical consequences. An individual’s subjective conclusion on the pandemic’s impact did not depend, in general, on socio-demographic factors. According to E. Diner’s model, our results show in favour of the stability of the cognitive component of an individual’s subjective well-being after almost a year of coronavirus in Ukraine. At the moment, there is no reason to claim changes in assessed life satisfaction. It is possible that these results demonstrate only initial changes in the pandemic situation and/or coronavirus stress factors on life satisfaction are mediated by personal characteristics, which are promising areas for further research. The higher life satisfaction was, the less noticeable the negative consequences of COVID-19 were.

Conceptualization and measurement of well-being have been carried out from different positions in positive psychology. In this cross-sectional study, the Scale of Positive and Negative Experiences (SPANE) has been adapted and validated on a sample of 458 Ukrainian adults. Confirmatory factor analysis has confirmed a two-factor model in which the positive affect (SPANE-P) and negative affect (SPANE-N) subscales were correlated (r = -0.594). The composite reliability was 0.909 for SPANE-P and 0.861 for SPINE-N. The mean removed variance was 0.630 for SPANE-P and 0.533 for SPANE-N, meaning converged validity is maintained. Discriminatory validity is satisfactory for both SPANE subscales, according to the Fornell and Larcker method and the HTMT test. The analysis of the measurement invariance of the SPANE testifies strict invariance for age and gender.
