This 5-day diary study examined the impact of daily hassles on well-being, with a focus on the mediating role of positive and negative affect. Previous research has extensively explored the effects of major life events on well-being, yet the influence of minor daily stressors remains poorly understood. We employed a daily diary methodology with 218 participants, aged 18 to 56, who reported their daily hassles, affect and well-being over five consecutive days. Results revealed that daily hassles significantly predicted both current and prospective well-being, mediated by changes in affect. Specifically, at the within-person level, negative affect increased and positive affect decreased in response to daily hassles, both contributing to reduced well-being. At the between-person level, only negative affect mediated this relationship. Our findings underscore the cumulative impact of minor daily stressors on well-being, highlighting the importance of affective responses in this process. This study contributes to a more nuanced understanding of how everyday stressors influence well-being, emphasizing the need for strategies to manage daily hassles and enhance emotional resilience.

In recent years, post-secondary students' mental health has become an important public health concern. However, studies examining protective factors of mental health among students and during challenging times are limited. Guided by the strength-based Resilience Portfolio Model and following a group of undergraduates (N = 1004) throughout the 2020/2021 academic year, this study examined multiple domains of resilience internal assets and external resources and simultaneously tested multiple protective mechanisms for student mental health using structural equation modelling. Results provided support for insulating effects: both internal assets such as emotion regulation and external recourses such as social network supportiveness and cultural fit in university (i.e., perceived congruity between students' personal and cultural selves and their university environment) were associated with reducing academic stress which in turn promoted student mental health at the end of the academic year. There was also support for additive effects: greater cultural fit in university was also directly related to better end-of-year student mental health. As cultural fit in university was associated both directly and indirectly with student mental health, creating an inclusive university community may help reduce student academic stress, lower student psychological distress and improve student subjective well-being.

Based on previous empirical evidence, scholars have argued for a dialectical relationship between burnout and work engagement. However, these conclusions largely rely on latent variable models, which have inherent limitations due to strong hierarchical assumptions about data. As a result, previous findings should be considered preliminary indications rather than conclusive evidence. In this study, we introduce network analysis to investigate the relationship between burnout and work engagement. We demonstrate its utility by comparing the fit indices of the network model and three factor models in a cross-national sample with 2469 employees from Norway and 879 employees from the US and UK. Based on theory and fit indices, we conclude that the network model was preferred in both samples. Using this model, we uncovered positive relationships between two work engagement variables and the exhaustion component of burnout. Theoretically, this study broadens our understanding and show support for the dialectical relationship between burnout and work engagement. Furthermore, by introducing the network model to empirical research, we provide a novel approach that contribute to nuance and ideas for research on burnout and work engagement. Practically, our results offer insightful data on possible points for intervention between burnout and work engagement variables.

The COVID-19 pandemic significantly impacted the psychological well-being of the general population. However, there are limited studies that examine its mental health effects on patients who have experienced traumatic injuries and tracked their recovery over time. This study aimed to: (1) compare the rates and severity of post-traumatic stress disorder (PTSD) and depression between patients who sustained traumatic injuries before the COVID-19 pandemic (pre-pandemic) and those injured during the pandemic (peri-pandemic); and (2) assess whether the degree of pandemic-related stress (e.g., worry about infection, social isolation, loss of home/job) predicted the severity of PTSD or depression symptoms. Participants (N = 198) were recruited from a Level 1 Trauma Centre in Southeastern Wisconsin following admission for a single-incident traumatic injury. Symptoms of PTSD and depression were assessed during hospitalisation and at three additional points within the subsequent 6 months. Self-report measures were used to evaluate PTSD and depression severity among patients injured before (pre-pandemic; n = 126) and during (peri-pandemic; n = 73) the pandemic. Peri-pandemic participants also completed a modified version of the COVID-19 Family Stress Screener to measure pandemic-related stress. Exploratory factor analysis was conducted to identify the dimensions of pandemic-related stress in our sample. The findings indicated that participants injured during the pandemic exhibited higher symptoms of PTSD and depression compared to those injured before the pandemic. Additionally, greater pandemic-related stress correlated with elevated levels of depression and PTSD at baseline. Our results highlight that the broader context in which patients recover from injuries can intensify the negative mental health consequences of traumatic injury. This underscores the need for enhanced access to psychological services for trauma patients, particularly during major societal stressors like a global pandemic.

Depression is one of the most common mental disorders. Perceived stress is a significant trigger and has adverse effects on depression. The complex longitudinal relationship between perceived stress and depression at the symptom level has significant implications for clinical intervention but is understudied. In our study, 823 students (67% female, median age 20.38, IQR 19.42-21.43) from a university in Tianjin were randomly sampled and completed measures of PHQ-9 and PSS-10, while 393 (65% female, median age 20.42, IQR 19.46-21.45) were followed up at three points, six months apart. The longitudinal relationships were estimated using cross-lagged modelling and cross-lagged panel network modelling. Among them, 49 students (59% female, median age 19.48, IQR 18.76-20.12) participated in resting-state functional magnetic resonance imaging (fMRI) scans. Cross-lagged analyses showed that depression and perceived stress predicted each other at the global level. At the dimensional level, depression and perceived helplessness were mutually predictive, while depression and perceived coping did not. In the cross-lagged panel network analyses, we identified symptoms in the top 20% of Bridge Expected Influence as bridging symptoms, specifically 'Guilt' (PHQ6) and 'Felt nervous and stressed' (PSS3). Notably, 'guilt' consistently demonstrated the highest Bridge Expected Influence across all time points and showed the strongest predictive power for perceived stress. We found that fALFF in the left superior frontal gyrus (SFG) mediated the association between "guilt" and perceived stress. Our findings elucidate the bidirectional relationship between symptoms of depression and perceived stress, identifying guilt is the most critical symptom of depression for the followed perceived stress, with SFG activity mediating this association.

Adverse childhood experiences (ACEs) are associated with long-lasting and multifaceted consequences for mental health. Despite established dose-response effects of ACEs on mental health, the specificity of ACE pattern effects remains understudied, especially on executive function. This study aims to explore how specific patterns of ACEs, beyond just cumulative scores, differentially impact emotional symptoms, personality and cognitive function. This study recruited 2515 college students from several universities in northern China. Demographic characteristics, depression, anxiety, borderline personality traits, and executive function (Wisconsin Card Sort Test) were assessed. Latent class analysis was used to identify patterns of ACEs. Data were analysed using χ²-test, ANCOVA, and multivariate linear regression methods. Pattern-oriented and cumulative-oriented approaches were compared to predict the effects of ACEs. Three distinct patterns of ACEs were identified: low adversity (LA), multiple adversity (MA), and family environment adversity (FA). FA with the highest number of ACEs was uniquely linked to executive function impairments, while both MA and cumulative ACEs significantly predicted higher anxiety, depression, and borderline personality traits. The pattern-oriented method was more sensitive to capturing the diverse outcomes of executive function impairment than cumulative scores. Our findings highlight the importance of moving beyond cumulative scores and considering specific ACEs patterns to understand their differential impact on mental health. Identifying FA as a distinct pattern with specific consequences for executive function offers valuable insights into developing targeted prevention strategies tailored to specific risk profiles.

The primary aim was to investigate how respiration rate and inhalation/exhalation ratio influence self-reported state anxiety during a single slow diaphragmatic breathing exercise session. Eight hundred and twenty-eight participants completed the study at two separate geographical locations (Poland and Spain). Participants performed a 10-min online guided breathing exercise. Respiration rates were sampled from a continuous uniform distribution (ranging from 6 to 12 breaths/min). Similarly, inhalation/exhalation ratios were treated as continuous variables and sampled from a uniform distribution for each participant. An application programed for this experiment displayed visual and auditory cues adjusted for each participant. Before and after the breathing exercise, each participant filled in the Current Anxiety Level Measure questionnaire. Self-trait anxiety was measured with the Clinically Useful Anxiety Outcome Scale. A linear regression model showed that respiration rate, trait anxiety, pre-test anxiety, and nationality (Polish/Spanish) were positively related to post-test anxiety levels. Adding quadratic terms of respiration rate and inhalation/exhalation ratio did not improve model fit. Polish participants exhibited higher post-test anxiety levels compared with the Spanish subsample. Age was negatively associated with post-test anxiety. No significant relationships between inhalation/exhalation ratio and post-test anxiety level were found. Slower respiration rates during a single-session breathing exercise are linearly associated with lower post-test anxiety levels in a large and varied sample. This study is the largest to date and may offer further guidance for predicting expected effect sizes for the relationships between anxiety and respiratory dynamics.

Integrating cognitive appraisal theory of stress and attachment theory, the current study explored the influence of daily workplace ostracism on employee short-term work engagement and examined the mediating role of negative work reflection and the moderating effects of employee attachment styles (i.e., attachment avoidance and attachment anxiety). To test the theoretical model, we employed an experience sampling method to collect daily diary data over 10 consecutive workdays, resulting in a final sample of 834 observations drawn from 133 participants. Results of multilevel path analysis indicated that daily workplace ostracism was negatively related to employee next-day work engagement through negative work reflection at night. In addition, we found that employee attachment avoidance not only moderated the within-person relationship between daily workplace ostracism and negative work reflection at night but also alleviated the indirect effect of daily workplace ostracism on next-day work engagement via negative work reflection at night. Taken together, our study contributed by unfolding the dynamic cognitive appraisal process of workplace ostracism and identifying the significant role of attachment avoidance in shaping employees' cognitive reactions to daily workplace ostracism.

The present study aimed to investigate the relationship between school bullying victimization and non-suicidal self-injury (NSSI) frequency, taking into consideration the mediating roles of coping strategies and emotional regulation. Participants were 12-18-year-old outpatients and inpatients who met the NSSI and depressive disorder criteria according to the DSM-5. Assessments included the Multidimensional Peer-Victimization Scale, Coping Style Scale for Middle School Students, Emotion Regulation Questionnaire for Children and Adolescents, and the Functional Assessment of Self-Mutilation to examine the bullying victimization, coping strategies, emotion regulation, and NSSI behaviour. Serial multiple mediation effects of coping strategies and emotion regulation between bullying victimization and NSSI frequency were analysed using the SPSS macro PROCESS programme. A total of 2335 participants were included in this study. Bullying victimization significantly predicted NSSI frequency (B = 0.191, p < 0.001). Both coping strategies and emotion regulation were important mediators in the relationship between bullying victimization and NSSI frequency. Bullying victimization indirectly affected NSSI through two serial mediation pathways: (1) bullying victimization → problem-focused coping → cognitive reappraisal → NSSI frequency, and (2) bullying victimization → emotion-focused coping→ expressive suppression → NSSI frequency. The study revealed a positive association between bullying victimization and the frequency of NSSI among adolescents with depressive disorder. Strategies of coping and emotional regulation significantly mediated the link between bullying victimization and the frequency of NSSI. The findings suggested that supporting adolescents in adopting effective coping and emotional regulation strategies could be a crucial approach to mitigate the impact of bullying victimization on the frequency of NSSI.

Parental stress can affect the ability of parents to cope with the challenges of raising children. The result can be a negative cycle within the family dynamic, which in turn can interfere with children's development and emotional regulation. Among the many instruments available to assess parental stress, the Parental Stress Scale (PSS) deserves particular mention. To our knowledge, there are currently no systematic reviews evaluating the psychometric properties of the PSS. The aim of this systematic review was to assess the psychometric properties of the PSS using the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) methodology and to conduct a meta-analysis. A thorough literature search was conducted from different databases. A meta-analysis to test the generalisability of PSS internal consistency across its component factors was performed. A total of 20 validation studies of the PSS were identified. Based on the COSMIN methodology, this instrument receives an 'A' rating, meaning that it is considered to be a cross-sectional instrument with the necessary scientific evidence for the assessment of the construct of parental stress. The meta-analysis testing the generalisability of its internal consistency yielded satisfactory results across the different factors. Future research should focus on those psychometric properties of the PSS that have not been studied as extensively, such as reproducibility, responsiveness, measurement error, and measurement invariance.
