Development of language-specific stress discrimination in European Portuguese: an electrophysiological study.

European Portuguese (EP) is a language with unpredictable stress. Previous behavioral studies have shown that without vowel reduction EP adult speakers displayed a stress deafness effect akin to that observed in speakers of fixed-stress languages, suggesting that vowel quality may be the primary cue for stress discrimination in EP. However, an event-related potentials (ERPs) study reported that EP adults were able to discriminate stress contrasts pre-attentively in the absence of vowel quality cues. These results seemed to indicate that EP adult speakers may attend to different cues in the attentive and pre-attentive stress perception. Moreover, both the behavioral and ERPs studies have revealed a processing advantage for iambic stress, which could not be predicted by the rhythmic properties of EP, the language-specific weighting of stress correlates, or the frequency distributions of trochaic and iambic stresses in EP. A recent eye-tracking study has found that EP-learning infants at 5-6 months already exhibited an iambic preference in the absence of vowel reduction, manifested by longer looking time at the iambic stress. The present study used a passive oddball paradigm to examine pre-attentive stress perception without vowel quality cues by 5-to-7-month-old EP-learning infants. Results from twenty-two participants showed that both the trochaic and iambic conditions yielded a positive discrimination response (p-MMR). In addition, the iambic condition elicited a prominent late discriminative negativity (LDN) as well as a P3a component. Our findings present the first evidence for reciprocal discrimination of stress patterns in EP-learning infants, showing that, as in adult speakers, stress processing might also differ at the pre-attentive and attentive stages in infants. Importantly, the stress perception ability in EP-learning infants seems to develop asymmetrically, with an advantage for the iambic stress pattern. The present study highlighted the role of language-specific factors that may affect developing stress perception.

Changes in Mental Health Among Adolescents in South Korea Before and After COVID-19: An Interrupted Time Series Analysis From 2015 to 2022.

PURPOSE: This study aimed to examine changes in mental health among adolescents by comparing data from the period following the onset of the COVID-19 pandemic with the period before the pandemic. METHODS: We estimated the annual prevalence of stress perception, depressive symptoms, and suicidal ideation among middle and high school students using data from the Korean Youth Health Behavior Survey spanning from 2015 to 2022. We then compared mental health status across 2 periods-pre-COVID-19 (2015-2019) and during COVID-19 (2020-2022)-employing an interrupted time series analysis. We adjusted for covariates, such as household economic status, residence type, self-rated health, and history of hospitalization, due to violence. RESULTS: We analyzed data from 472,385 adolescents (242,819 boys and 230,016 girls). Stress perception, depressive symptoms, and suicidal ideation showed an increasing trend during the pre-COVID-19 period, followed by a decrease in the first year of the pandemic and an increasing trend in the second and third years. Boys experienced a faster increase in stress and depressive symptoms during the second and third years of the pandemic compared with the pre-COVID-19 period, whereas girls showed trends similar to those observed before the pandemic. Middle school students experienced a more rapid increase in these indicators than high school students during the second and third years. DISCUSSION: Adolescents' mental health initially improved in the first year of COVID-19 but worsened during the second and third years of the pandemic. This suggests a need for intervention policies and programs to support adolescent mental health.

Exploring the Interplay between Stress Perception and Approach-Avoidance Achievement Goal Orientation among Rural Students in College: A Longitudinal Study in China.

The objective of this study was to examine the relationship between stress perception and achievement goals among rural college students in China. Using a two-wave random intercept cross-lagged model, this study analyzed data from a longitudinal survey conducted at 15 public universities in Beijing. First, there was a significant decline in stress levels among Chinese rural students from their junior to senior years. Second, the achievement goal orientations of these students remained relatively stable during the period. Third, while no significant association was found between approach goals and stress perception, a clear positive reciprocal relationship emerged between avoidance goals and stress perception. These results suggest that educators should focus on alleviating the stress experienced by rural college students through academic, employment, and interpersonal support to break the vicious cycle of stress perception and avoidance goal orientation. Future research should further explore the influence of diverse group characteristics and emotional states on these outcomes.

Stress perception and associated factors among patients with Parkinson's disease: a cross-sectional study after the COVID-19 pandemic.

BACKGROUND: Parkinson's disease (PD) is a serious neurodegenerative disease that brings great stress to the physical and mental health of patients. At the same time, long-term treatment will also bring great economic losses and social burden to the family and society, especially after COVID-19 pandemic. The aim of this study is to analyze the current status of stress perception and anxiety in patients with PD and explore the influencing factors after the COVID-19 pandemic. METHODS: This study used the convenient sampling method to select the research objects of patients with PD who were outpatients or inpatients in a general public hospital in Hangzhou, Zhejiang Province, and the survey time was from February 2023 to March 2023. The measurements included the General information questionnaire, The Perceived Stress Scale (PSS) and The Self Rating Anxiety Scale (SAS). SPSS 21.0 software was used for data statistical analysis. RESULT: 394 out of 420 patients with PD completed the questionnaire. The stress perception score of PD was (16.41 ± 6.435) and the anxiety score was (54.77 ± 10.477). The stress perception scores of patients with PD were significantly different in gender, age, educational, occupation, nature of costs, time of sleep, quality of sleep, duration of disease, way of medical treatment and anxiety level (p < 0.05). Among them, age, duration of disease, public expenses, online remote therapy and anxiety level were the main influencing factors of stress perception in patients with PD (p < 0.05). Besides, there were significant differences in gender, educational, nature of costs, time of sleep, quality of sleep and duration of disease in anxiety among patients with PD (p < 0.05). CONCLUSION: After the COVID-19 pandemic, the level of stress perception and anxiety in patients with PD is high, and the influencing factors are complex.

Relationship between childhood trauma and non-suicidal self-injury in high school students: the mediating role of the stress perception and the moderating role of teacher-student relationship.

This study delves into the correlation between childhood trauma and non-suicidal self-injury (NSSI) behaviors among high school students. Additionally, it examines the mediating role of stress perception and the moderating role of the teacher-student relationship in this association. A questionnaire survey was administered to 1,329 high school students in Yunnan Province to assess childhood trauma, NSSI behaviors, and stress perception. Firstly, the survey revealed a 12% prevalence of NSSI, with girls exhibiting a higher occurrence compared to boys (OR = 0.413, 95% CI: 0.280-0.609). Secondly, childhood trauma emerged as a significant predictor of NSSI behavior, irrespective of gender or whether the individual was an only child (r = 0.17, P < 0.01). Thirdly, stress perception functioned as a mediator in the relationship between childhood trauma and NSSI among high school students (t = 4.65, P < 0.01). The mediation effect occupies 26.56% of the total effect. Furthermore, the teacher-student relationship moderated the mediating effect of stress perception on the link between childhood trauma and NSSI (ß = 0.0736, P < 0.01). Notably, individuals with strong teacher-student relationships exhibited a significant elevation in stress perception upon exposure to childhood trauma. The findings of this study support a moderated mediation model in the association between childhood trauma and NSSI, suggesting profound implications for the development of targeted interventions and prevention strategies among high school students.

The impact of telecom industry employees' stress perception on job burnout: moderated mediation model.

BACKGROUND: The rapid development of the telecommunications industry in the post-COVID-19 era has brought tremendous pressure to employees making them a high-risk group for job burnout. However, prior research paid less attention to the burnout of employees. Furthermore, social support and gender have separate effects on job burnout. This study explores the mechanism of stress perception on job burnout and examines the roles of social support and gender amid it. METHOD: This cross-sectional study was conducted from June 2023 to August 2023 in mainland China. A total of 39,507 were recruited by random sampling and online questionnaires, and 28,204 valid questionnaires were retained. SPSS (version 26.0) and PROCESS (Model 4 & 7) were used for correlation analysis, mediation analysis, and mediated moderation analysis. RESULT: Stress perception can positively predict the level of job burnout of employees in the telecommunications industry, and social support plays a partial mediating role, accounts for 8.01% of the total effect, gender moderates the first half of the path in this mediation model. At the same pressure level, female can perceive more social support than male. CONCLUSIONS: Under high pressure background, employees' job burnout varies depending on gender and the perception of social support. Therefore, telecommunications industry managers should adopt decompression measures and targeted social support resources for different groups.

The effect of childhood trauma on depression in college students: A moderated mediation model.

OBJECTIVE: Childhood trauma is considered as a critical risk factor for depression. Although many studies have investigated the pathway of Childhood trauma to depression, especially the mediating or moderating effects of cognitive emotion regulation strategies or neuroticism or stress perception, the results were inconsistent and the underlying psychological mechanisms of depression remain unclear. This study aims to explore the influence and mechanism of childhood trauma on depression in college students, and establish a full model among these interactive factors. METHODS: 1272 college students were surveyed using the childhood trauma questionnaire (CTQ), short version of center for epidemiologic studies depression scale (CES-D), Chinese perceived stress scale (CPSS), neuroticism extraversion openness five-factor inventory (NEO-FFI), and the Cognitive Emotion Regulation Questionnaire (CERQ). RESULTS: (1) Childhood trauma, neuroticism, stress perception, and maladaptive cognitive emotion regulation strategies were all significantly and positively correlated with depression among college students; (2) Stress perception and neuroticism act as a chain mediator between childhood trauma and depression in college students. (3) Maladaptive cognitive emotion regulation strategies play a moderating role in "childhood trauma-neuroticism-depression". CONCLUSION: Childhood trauma increases the risk of depression in college students by affecting neuroticism and stress perception, and high levels of maladaptive cognitive emotion regulation strategies link neuroticism and enhance the effect of childhood trauma on depression in college students.

Dreaming while awake: The beneficial effects of yoga Nidra on mental and physical recovery in two elite karate athletes.

Yoga Nidra (YN) naturally stimulates a hypnagogic state wherein an individual is physiologically asleep yet maintains a certain awareness to follow a guide's instructions. The aim of this study was to investigate the effects of this aware sleep state on recovery-stress balance in two elite karate athletes adopting an idiosyncratic and multimodal approach. One male and one female athlete underwent a YN intervention. Before intervention, after intervention and three weeks later, recovery-stress balance specific scales, perceived stress, cognitive and somatic anxiety, subjective and objective sleep quality, and individual alpha peak frequency (iAPF) values were assessed. Perceived quality of recovery was continuously monitored for three months including the period of the investigation. Feelings and arousal levels before and after each YN session were also examined. Our results showed a YN general positive effect; however, the intervention had higher sport specific effects in the male compared to the female athlete. On the other hand, in the female athlete, YN seems to have effects both from an emotional and physical point of view. We also noted the intertwined relationship among interoception, perceived stress and YN effects. Also, findings suggest that iAPF modulation reflected improved recovery skills or a better control of stressful situations, while the acute effects on arousal levels were expression of anxiety or energy reduction. Overall, YN improved both the perceived quality of recovery and sleep quality, shedding light on the importance of YN for recovery-stress balance enhancement in the sport context.

The relationship between stress perception and sleep quality among college students: chain mediating effect of expression inhibition and anxiety emotions / 中华行为医学与脑科学杂志

Objective:To explore the relationship between stress perception and sleep quality among college students, as well as the chain mediating role of expression inhibition and anxiety emotions.Methods:From October to December 2022, a cross-sectional survey was conducted among 785 college students using the perceived stress scale (PSS-14), emotion regulation questionnaire (ERQ), self-rating anxiety scale (SAS), and Pittsburgh sleep quality index (PSQI). SPSS 26.0 software was used for common method bias testing, Pearson correlation analysis, and stratified regression analysis.PROCESS 3.5 macro program was used for mediating effect test.Results:(1) The correlation analysis results indicated that there were significant positive correlations between stress perception (39.22±7.63), expression inhibition (15.95±4.28), anxiety (45.85±11.70) and sleep quality (5.87±3.28)( r=0.120-0.596, all P<0.05). (2) The results of path analysis showed that stress perception could directly predict sleep quality, with a effect size of 0.243 (95% CI=0.172-0.313). Stress perception could indirectly affect sleep quality through anxiety emotion, with a effect size of 0.229 (95% CI=0.178-0.283). Stress perception could affect sleep quality through the chain mediation of expression inhibition and anxiety emotion, and the effect size was 0.010 (95% CI=0.002-0.019). Conclusion:Stress perception can directly predict sleep quality, and can also indirectly predict sleep quality through partial mediating effects of anxiety and chain mediating effects of expression inhibition and anxiety.

Salt stress perception and metabolic regulation network analysis of a marine probiotic Meyerozyma guilliermondii GXDK6.

Introduction: Extremely salt-tolerant microorganisms play an important role in the development of functional metabolites or drug molecules. Methods: In this work, the salt stress perception and metabolic regulation network of a marine probiotic Meyerozyma guilliermondii GXDK6 were investigated using integrative omics technology. Results: Results indicated that GXDK6 could accept the salt stress signals from signal transduction proteins (e.g., phosphorelay intermediate protein YPD1), thereby contributing to regulating the differential expression of its relevant genes (e.g., CTT1, SOD) and proteins (e.g., catalase, superoxide dismutase) in response to salt stress, and increasing the salt-tolerant viability of GXDK6. Omics data also suggested that the transcription (e.g., SMD2), translation (e.g., MRPL1), and protein synthesis and processing (e.g., inner membrane protein OXA1) of upregulated RNAs may contribute to increasing the salt-tolerant survivability of GXDK6 by improving protein transport activity (e.g., Small nuclear ribonucleoprotein Sm D2), anti-apoptotic ability (e.g., 54S ribosomal protein L1), and antioxidant activity (e.g., superoxide dismutase). Moreover, up to 65.9% of the differentially expressed genes/proteins could stimulate GXDK6 to biosynthesize many salt tolerant-related metabolites (e.g., ß-alanine, D-mannose) and drug molecules (e.g., deoxyspergualin, calcitriol), and were involved in the metabolic regulation of GXDK6 under high NaCl stress. Discussion: This study provided new insights into the exploration of novel functional products and/or drugs from extremely salt-tolerant microorganisms.Graphical Abstract.

ERP evidence for Slavic and German word stress cue sensitivity in English.

Word stress is demanding for non-native learners of English, partly because speakers from different backgrounds weight perceptual cues to stress like pitch, intensity, and duration differently. Slavic learners of English and particularly those with a fixed stress language background like Czech and Polish have been shown to be less sensitive to stress in their native and non-native languages. In contrast, German English learners are rarely discussed in a word stress context. A comparison of these varieties can reveal differences in the foreign language processing of speakers from two language families. We use electroencephalography (EEG) to explore group differences in word stress cue perception between Slavic and German learners of English. Slavic and German advanced English speakers were examined in passive multi-feature oddball experiments, where they were exposed to the word impact as an unstressed standard and as deviants stressed on the first or second syllable through higher pitch, intensity, or duration. The results revealed a robust Mismatch Negativity (MMN) component of the event-related potential (ERP) in both language groups in response to all conditions, demonstrating sensitivity to stress changes in a non-native language. While both groups showed higher MMN responses to stress changes to the second than the first syllable, this effect was more pronounced for German than for Slavic participants. Such group differences in non-native English word stress perception from the current and previous studies are argued to speak in favor of customizable language technologies and diversified English curricula compensating for non-native perceptual variation.

Anxiety, Stress Perception, and Coping Strategies among Students with COVID-19 Exposure.

Background: Studying anxiety, stress, and coping strategies during the COVID-19 pandemic is crucial to mitigate the negative effects associated with infection risk and disease consequences. Objective: This study aimed to investigate anxiety levels, stress perception, and coping strategies in relation to the presence of illness. Material and Methods: A cross-sectional online survey was conducted anonymously among 3950 university students from Poland (1822), Lithuania (232), and the Russian exclave of Kaliningrad (1896). Due to the nearly identical application of anti-epidemic measures, the respondents were treated as a unified group. The State-trait Anxiety Inventory (STAI), Perceived Stress Scale 10 (PSS-10), and mini-COPE scale questionnaires were used. Statistical analysis included the Shapiro-Wilk test to check normality, the Mann-Whitney U test for comparative analysis between groups, the Pearson χ2 test for categorical data, and Spearman coefficients for correlations between variables. Results: A significant proportion of young adults in the community exhibited symptoms of anxiety and stress during the COVID-19 pandemic. Among the 1212 men and 2738 women surveyed, 348 (28.7%) and 1020 (37.3%) individuals, respectively, were diagnosed with COVID-19 according to clinical protocols. Prolonged disease duration and more severe residual symptoms correlated with higher self-reported anxiety levels. Conclusions: The level of anxiety and stress varied depending on the duration of the disease, significantly impacting the choice of coping strategies. Overall, students displayed a proactive approach to coping activities but tended to postpone important decisions. Seeking social support was a prevalent coping mechanism, although respondents who had COVID-19 showed higher levels of concern for their own emotions, a tendency to discharge emotions through alcohol or other substances (male), and a greater reliance on religion (female). The study provides data that may be useful in developing educational and health policies focused on the mental well-being of university students and potentially other social groups.

The Relationship between Stress Perception and Problematic Social Network Use among Chinese College Students: The Mediating Role of the Fear of Missing Out.

Based on the interaction of person-affect-cognition-execution model, this study examined the association between stress perception and problematic social network use among Chinese college students and explored the mediating effect of the fear of missing out (FoMO) on the relationship between stress perception and problematic social network use. A questionnaire survey was conducted among 554 students from nine universities in China. We found that stress perception was significantly positively correlated with problematic social network use and FoMO (r = 0.38, 0.46; p < 0.001), and FoMO was significantly positively correlated with problematic social network use (r = 0.45, p < 0.001). FoMO mediated the relationship between stress perception and problematic social network use. Conclusion: Stress perception has a negative impact on college students' problematic social network use via the mediating effect of FoMO. Practical implications that reveal the college students' problematic social network use were discussed as well.

The association between how medical students were selected and their perceived stress levels in Year-1 of medical school.

BACKGROUND: The prevalence of medical students' mental distress is high. While schools apply various methods to select a well-performing and diverse student population, little is known about the association between different selection methods and the well-being of these students during medical school. The present retrospective multi-cohort study assessed whether students selected by high grades, assessment, or weighted lottery showed different stress perception levels in Year-1 of medical school. METHODS: Of 1144 Dutch Year-1 medical students, 650 (57%) of the cohorts 2013, 2014, and 2018 who were selected by high grades, assessment, or weighted lottery completed a stress perception questionnaire (PSS-14). A multilevel regression analysis assessed the association between selection method (independent variable) and stress perception levels (dependent variable) while controlling for gender and cohort. In a post-hoc analysis, academic performance (optimal vs. non-optimal) was included in the multilevel model. RESULTS: Students selected by assessment (B = 2.25, p < .01, effect size (ES) = small) or weighted lottery (B = 3.95, p < .01, ES = medium) had higher stress perception levels than students selected by high grades. Extending the regression model with optimal academic performance (B=-4.38, p < .001, ES = medium), eliminated the statistically significant difference in stress perception between assessment and high grades and reduced the difference between weighted lottery and high grades from 3.95 to 2.45 (B = 2.45, p < .05, ES = small). CONCLUSIONS: Selection methods intended to create a diverse student population - assessment and lottery - are associated with higher stress perception levels in Year-1 of medical school. These findings offer medical schools insights into fulfilling their responsibility to take care of their students' well-being.

Osmosensing in plants: mystery unveiled.

Osmotic stress limits plant growth and productivity. The downstream signaling components involved in osmotic adjustments are well known, but our knowledge of the perception of osmotic stress is far too limited. Wang et al. have recently identified a lesser-known mechanism of bimolecular condensation that underlies osmotic stress perception in plants.

Minority stress and sleep: How do stress perception and anxiety symptoms act as mediators for sexual minority men?

OBJECTIVES: Sexual minority men experience worse sleep than heterosexuals. Little is known about how minority stress may account for these differences. Therefore, the aims of this study are to (1) understand the relationship between minority stress and sleep disturbance in a sample of sexual minority men, and (2) test whether these relationships are mediated by generalized anxiety symptoms and perception of stress. METHODS: In 2020, 239 sexual minority men were recruited to complete an online survey. Participants responded to scales assessing minority stress (ie, internalized homophobia, experiences of harassment, microaggressions), perception of stress, generalized anxiety symptoms, and sleep disturbance. Linear regressions were used to test the relationship between minority stress and sleep disturbance and to test generalized anxiety symptoms and perception of stress as mediators. RESULTS: The final model was significant (F = 16.916, p < .001) and accounted for 43.5% of the variance in sleep disturbance. Generalized anxiety symptoms and perception of stress fully mediated the relationships between minority stress and sleep disturbance. CONCLUSIONS: Findings from this study suggest the need for psychological intervention to improve sleep for sexual minority men. Future research should test this model longitudinally, and include objective measures of stress. Future interventions could target stress perception using mindfulness or cognitive-based interventions.

Differences in Stress Perception of Medical Students Depending on In-Person Communication and Online Communication during the COVID-19 Pandemic: A Japanese Cross-Sectional Survey.

BACKGROUND: Excessive psychological stress in medical students affects their mental health and causes problems such as burnout and depression. Furthermore, changes in the learning environment to online learning due to the COVID-19 pandemic have had a psychological effect on medical students. However, the relationships between medical students' perceived stress and different methods of communication, including in-person and online communication, remain unclear. The purpose of this study was to investigate the differences in stress perception of medical students depending on in-person communication and online communication during the COVID-19 pandemic. METHODS: This study was a cross-sectional study conducted from September to October in 2020. All of the students of Okayama University School of Medicine were asked to participate in a questionnaire survey. The explanatory variables were the frequency and length of communications with others (by in-person or online communication), empathy, and lifestyle. The main outcome measure was perceived stress. Subgroup analysis was conducted for students who preferred to be by themselves and students who preferred to study together and interact with other people. Univariate analysis and multivariate multiple regression analysis were conducted. Gender and grade, which have been shown to be associated with stress in previous studies, were used as covariates for multiple regression analysis. RESULTS: Valid responses to the questionnaire survey were received from 211 (29.4%) of the 717 students. There was no significant association between perceived stress and online communication, but the number of people with which students had in-person communication (1-2 people compared to 0 as a control, regression coefficient [B] = -4.4, 95% confidence interval [CI]; -7.8, -1.1, more than 10 people, B = -12, 95% CI: -18, -5.8) and the length of communication (more than 120 min, B = -4.5, 95% CI: -8.1, -0.92) were associated with a reduction in perceived stress. In subgroup analysis, the number of people with in-person communication and the length of communication had significant associations with stress reduction even in the group of students who had a preference for being by themselves. CONCLUSION: In-person communications rather than online communications were associated with a lower level of perceived stress. In subgroup analysis, this trend was statistically significant in the group of students who had a preference for being by themselves.

Effect of stress perception on depression in medical staff: the mediating role of resilience / 中华行为医学与脑科学杂志

Objective:To explore the impact of stress perception on depression and the potential mediating role of resilience in medical staff.Methods:A total of 606 medical staff were recruited and investigated by self-designed questionnaire, the perceived stress scale (PSS-10), the 10-item Connor-Davidson resilience scale (CD-RISC-10), and the patient health questionnaire-9 (PHQ-9) from February to March, 2020.SPSS 26.0 software was used to execute Pearson or Spearman correlation analysis, common method biases test, and multicollinearity test.Model 4 in PROCESS 3.2 macro program and Bootstrap method were used for mediating effects analysis.Results:There was a positive correlation between stress perception score(16.93±6.65) and depression score (5.00(2.00, 9.00))( r=0.551, P<0.01), and a negative correlation between stress perception score and resilience score (27.08±8.68) ( r=-0.285, P<0.01) among 606 medical staff.There was a negative correlation between resilience score and depression score ( r=-0.474, P<0.01). Mesometric effect examination showed that resilience played a partial mediating role in the relationship between stress perception and depression, and the mediating effect accounted for 10.87% of the total effect. Conclusion:Stress perception can directly or indirectly influence depression scores, and resilience partially mediates the relationship between stress perception and depression.Depression can be reduced clinically by reducing stress perception or enhancing the resilience of medical personnel.

The Stressful Personality: A Meta-Analytical Review of the Relation Between Personality and Stress.

The current study presented the first meta-analytic review on the associations between the Big Five personality traits and stress measured under different conceptualizations (stressor exposure, psychological and physiological stress responses) using a total of 1,575 effect sizes drawn from 298 samples. Overall, neuroticism was found to be positively related to stress, whereas extraversion, agreeableness, conscientiousness, and openness were negatively linked to stress. When stress assessed under different conceptualizations was tested, only neuroticism, agreeableness, and conscientiousness were related to stressor exposure. All of the Big Five personality traits were significantly associated with psychological stress perception, whereas the five personality traits showed weak to null associations with physiological stress response. Further moderation analyses suggested that the associations between personality traits and stress under different conceptualizations were also contingent upon different characteristics of stress, sample, study design, and measures. The results supported the important role of personality traits in individual differences in stress.

The relationship between resilience and psychological distress of left-behind female college students: the mediating role of cognitive reappraisal and the moderating role of stress perception / 中华行为医学与脑科学杂志

Objective:To explore the relationship between resilience and psychological distress among female college students with left-behind experience, and the role of cognitive reappraisal and stress perception in it.Methods:From May to June 2020, a total of 4 008 female college students with experience of being left-behind were sampled by the whole group sampling method. All participants were evaluated by the Connor-Davidson resilience scale, the cognitive reappraisal scale of the emotion regulation questionnaire, the stress perception scale-10 and Kessler psychological distress scale. The PROCESS macro program of SPSS 25.0 was used to test the mediating effect of cognitive reappraisal and the moderating effect of stress perception.Results:(1) The measure of psychological distress showed that the detection rate was 13.46% for male college students with left-behind experience, 12.93% for male college students without left-behind experience, and 11.40% for female college students with left-behind experience and 9.26% for female college students without left-behind experience.(2) The scores of cognitive reappraisal, stress perception and psychological distress for female college students with left-behind experience were significantly different in terms of grade level ( F= 3.52, 3.54, 3.49, all P<0.05). (3) Resilience(58.39±13.64) showed a significant positive correlation with cognitive reappraisal(31.28±5.09) ( r=0.51, P<0.001) and a significant negative correlation with stress perception(16.42±5.49)and psychological distress(21.62±7.76)( r=-0.41, -0.30, both P<0.001). Cognitive reappraisal showed a significant negative correlation with stress perception and psychological distress ( r=-0.33, -0.27, both P<0.001). Psychological distress showed a significant positive correlation with stress perception ( r=0.67, P<0.001). (4)Stress perception played a moderating role between cognitive reappraisal and psychological distress. The effect of cognitive reappraisal on psychological distress was not significant under low levels of stress perception( βsimple=-0.01, P=0.52). Under high levels of stress perception, cognitive reappraisal had a significant negative effect on psychological distress( βsimple=-0.08, P<0.001). Conclusion:Resilience of female college students with left-behind experiences can directly affect psychological distress or indirectly through cognitive reappraisal, and this mediating model is moderated by stress perception.
