Introduction The 8-item Stress Mindset Measure-General (SMM-G) is an instrument designed to assess stress-is-enhancing and stress-is-debilitating mindsets. The stress-is-enhancing stress mindset positively correlates with well-being indices and work productivity and negatively correlates with depression and anxiety scores. Mindset could be changed after a psychological, psychoeducational, or psychotherapeutic intervention. Objectives We aim to adapt the SMM-G for adolescents and to explore its factor structure and psychometric properties in a sample of Russian students. Methods A total of 564 Russian students (337 men, 229 women) from 9 universities aged 17 to 23 years (М=19,9) participated in the study. We computed reliability indicators, conducted exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results Psychometric indicators are shown in Table 1. As a result of EFA (maximum likelihood, varimax rotation), two factors (eigenvalues 3,430 and 1,645) were extracted, accounting for 42,9% and 20,6% explained variance. Then, we tested the proposed model via CFA (Table 2). Table 1. Psychometric indicators Mean value ± std Cronbach`s alpha Test-retest reliability (n=179, one month between assessments) 1,175±0,165 0,805 0,563 The first factor includes all odd-numbered questions, while the second factor contains all even-numbered questions. This is consistent with the questionnaire’s structure, leading to a natural interpretation of factors as the stress-is-enhancing and stress-is-debilitating mindsets. Table 2.

IntroductionFuture firefighters are trained and selected for a job requiring the ability to perform well under high stress and time pressure.ObjectivesThe research is focused on the experimental study of fire cadets’ cognitive performance indicators (speed/accuracy) under stress.MethodsThe study follows Solomon Four Group Design with two variables: stress stimuli (exposure/non-exposure) and participants’ background (50 male fire cadets; 50 male civilian students). Stress stimuli consisted of emergencies’ photos, audio, videos. ECG, EMG, systolic wave amplitude, pulse transit time were measured during the experiment to determine the respondents’ stress levels. The cognitive reflection test (CRT) was performed. Mann-Whitney U-test, Spearman’s rank correlation coefficient were used.ResultsThere were no differences between students and fire cadets in CRT time (p=0.515, students: 118.1±38.6 sec, cadets: 143.5±78.1 sec) and accuracy (p=0.246, students: 1.2±0.9, cadets: 1.4±0.9). Fire cadets in the stress exposure group (mean time=122, mean accuracy=1.22) performed CRT significantly faster (p=0.039) than non-exposed cadets (mean time=166, mean accuracy=1.56). The accuracy difference was insignificant (p=0.206). Fire cadets with prior emergency work experience (n=30, mean time=159.7, mean accuracy=1.6) were no different from other cadets (n=20, mean time=159.7, mean accuracy=1.1) both in time (p=0.289) and accuracy(p=0.07). The performance difference between civilian student groups was insignificant (exposure: mean time=123, mean accuracy=1.32; non-exposure: mean time=113, mean accuracy=1.06).ConclusionsStress exposure enhances fire cadets’ CRT performance (in speed, but not in accuracy). Emergency work experience did not contribute to this effect, which could be explained by the self-selection effect (since only people inclined to emergency work choose to become a firefighter).DisclosureNo significant relationships.

IntroductionThe COVID-19 pandemic situation is seen as an intense stressor. However, people process it differently.ObjectivesThis study aims to examine the connection between life situation perception and the desirability of life changes the pandemic caused.MethodsAdult participants (n=144; 01.04.2020–01.06.2020) answered open-ended questions about their current life situation experience and rated the desirability of life changes on a 10-point scale (see table 1). Content analysis and Pearson’s χ2 criterion were used.Table 1Changes’ desirability-5-4-3-2-1+1+2+3+4+5Group 1Group 2Group 3Group 4Rejecting changesAccepting changesResultsWe annotated the participants’ responses. The content of life situations was categorized into restrictions, losses, difficulties (negative responses), acquisitions (positive responses), neutral, and ambivalent responses. Life goals were categorized into an approach to the desired outcome, avoidance of hassles, preservation of status quo, self-development, and return to prepandemic life. χ2 analysis confirms the differences between content-types and goal-types categories in 4 groups of participants: χ2(15)=43.62; p=0.002 (content); χ2(12)=27.23; p=0.01 (goals). The desirability of changes was positively linked with the ambivalent responses and responses containing self-development goals or approach-to-desired-outcome goals; and was negatively linked with the responses containing restriction-type situations and avoidance goals. Only the respondents accepting changes reported acquisitions; only the respondents rejecting changes reported a return to prepandemic life goals.ConclusionsPerceived characteristics of life situations are closely connected with the desirability of life changes during the pandemic.

Введение. Исследуется влияние стрессогенного воздействия умеренной интенсивности на кратковременную память, что востребовано практикой подготовки специалистов экстремального профиля (спасателей) к профессиональной деятельности. Объектом исследования является изменение объема кратковременной памяти под воздействием стрессогенных факторов. Определено существование значимых различий между показателями памяти курсантов и студентов специальностей, не связанных с деятельностью в экстремальных условиях. Новизна заключается в проведенном экспериментальном исследовании влияния стрессогенного воздействия на объем кратковременной памяти с учётом фактора профессиональной направленности испытуемых. Методы. В исследовании приняли участие 90 человек: 50 курсантов силового ведомства и 40 студентов московских вузов. Испытуемые были разделены на четыре группы, из которых одна экспериментальная и три контрольные. Двум группам были предъявлены фото- и аудиоматериалы стрессогенного содержания; двум другим группам – материалы нейтрального содержания. Объем кратковременной памяти испытуемых до и после предъявления материалов определялся при помощи методики Digit Span Test. На протяжении всего эксперимента замерялись физиологические параметры испытуемых. Результаты. У курсантов силового ведомства объем памяти в стрессогенных условиях значимо увеличивается, в то время как объем памяти студентов показывает незначимое снижение. Также в стрессогенных условиях студенты и курсанты демонстрируют разный физиологический ответ: студенты имеют более высокое исходное мышечное напряжение, в то время как показатели сердечно-сосудистой системы курсантов (амплитуда систолической волны, время распространения пульсовой волны) меняются быстрее, при этом не так выраженно, как у студентов. Обсуждение результатов. Показатели объема памяти и его устойчивость к стрессогенным воздействиям курсантов связаны с уровнем невербального интеллекта, а также могут быть опосредованы профессионально-важными качествами и мотивационными особенностями. В качестве важного фактора устойчивости когнитивных функций рассматривается система отбора и психологического сопровождения курсантов силового ведомства.
