Cortisol and heart rate variability (HRV) are well-established biomarkers of the human stress response system. While a relationship between cortisol and HRV is assumed, few studies have found evidence of their correlation within single study designs. One complication for isolating such a relationship may lie in individual variability in the cortisol response to stress such that atypical cortisol responding (i.e., elevated or blunted) occurs. To-date, studies on the cortisol response have employed traditional mean-difference-based approaches to examine average magnitude change in cortisol over time. Alternatively, data-driven trajectory modelling, such as latent growth mixture modelling, may be advantageous for quantifying cortisol based on patterns of response over time. Latent growth mixture modelling was used in N = 386 adults to identify subgroups based on trajectories of cortisol responses to stress. The relationship between cortisol and HRV was tested within subgroups. Results revealed a 'prototypical' subgroup characterised by expected rise and fall in cortisol response to stress (n = 309), a 'decline' subgroup (n = 28) that declined in cortisol after stress, and a 'rise' subgroup (n = 49) that increased in cortisol after stress. Within the 'prototypical' subgroup, greater HRV during stress was associated with decline in cortisol after stress from its maximum (r (306) = 0.19, p < 0.001). This relationship failed to emerge in the 'decline' and 'rise' subgroups (p > 0.271). Results document different patterns of cortisol response to stress; among those who exhibit a 'prototypical' response, changes in HRV during stress are related to changes in cortisol after stress.

Experiencing parental death during childhood is an adverse, potentially traumatic experience that may have substantial long-term effects on mental and physical well-being. The current study was based on data of the Netherlands Study of Depression and Anxiety to investigate mental health (i.e., depressive symptoms, anxiety symptoms, and suicidal ideation) and physical health outcomes (i.e., metabolic syndrome, telomere length, and perceived physical health) as well as health behaviour (i.e., smoking status, alcohol use, and physical activity) to provide more insight into the long-term outcomes after experiencing childhood parental death (CPD). For individuals who experienced CPD, we also investigated the role of loss-related factors in these associations, namely the age of the child when their parent passed away and gender of the deceased parent. Interviews and questionnaires were completed by adults between 18 and 65 years; 177 participants experienced CPD (mean age = 45.19, 61.6% female) and 2463 did not (mean age = 41.38, 66.6% female). Results showed no overall association between the experience of CPD and mental and physical health indices and health behaviour. Within the CPD group, experiencing CPD at a younger age was related to a higher likelihood of suicidal ideation. These findings seem to illustrate a general positive adjustment with regard to long-term health functioning after experiencing such an impactful life event. Future research should focus on individual differences in terms of adaptation, especially elucidating on contextual factors after the loss, such as the kind of support that is or is not provided by the surviving parent and/or other important individuals.

Job boredom refers to an unpleasant state of passiveness at work that has been found to negatively relate to self-reported health. To date, however, the relation between job boredom and physiological indicators of health has not been examined. The present study investigates whether job boredom relates to dysfunction in autonomic nervous system (ANS) activity as indicated by reduced heart rate variability (HRV) during night sleep. The sample of this study consisted of Finnish public sector workers (n = 125). Job boredom was assessed with an electronic questionnaire and HRV with an ambulatory monitoring period of two nights of sleep. The results supported the hypothesis by showing a negative relation between job boredom and HRV, after controlling for demographic and lifestyle factors. The findings extend previous knowledge on the detrimental consequences of job boredom by showing that it is related to dysfunction in ANS activity. Consequently, it is important to acknowledge boredom at work as a threat to occupational health and well-being and pay more attention to how it can be prevented at workplaces.

The aim of the present study was to illuminate the causal relationships between self-esteem and test anxiety, as well as between general self-efficacy and test anxiety using two-wave longitudinal research design with a sample of 252 Chinese college students. After controlling for gender, grade and autoregressive effects, the results revealed that (1) self-esteem at T1 did not significantly predict test anxiety at T2; (2) general self-efficacy at T1 did not significantly predict test anxiety at T2; (3) test anxiety at T1 significantly and negatively predicted self-esteem at T2; and (4) test anxiety at T1 marginally significantly and negatively predicted general self-efficacy at T2. These results suggest that test anxiety is more likely to affect self-esteem and general self-efficacy rather than vice versa, and that the causal relationship between self-esteem and test anxiety are clearer than the causal relationship between general self-efficacy and test anxiety. However, given the limitation of the longitudinal research using cross-lagged analysis for revealing causality, these results should be viewed with caution.

The COVID-19 pandemic resulted in a reorganization of adolescents' routines, especially their sleep schedules. Utilising 175 caregiver-adolescent dyads, the current study examined associations of biological (e.g., prenatal substance use), environmental (e.g., poverty), and relational (e.g., child maltreatment) subtypes of early life adversity (ELA) with various components of adolescents' sleep across the first year of the COVID-19 pandemic. Relational ELA explained unique variance in adolescents' sleep disturbances, but not other sleep components, following short- and longer-term exposure to the COVID-19 pandemic. However, the direction of this association switched such that relational ELA predicted decreased sleep disturbances during the initial phase of the U.S. COVID-19 pandemic in spring 2020 beyond pre-pandemic levels, but, over time, contributed to increased sleep disturbances beyond early-pandemic levels as the pandemic extended into the winter of 2020.

The job crafting literature has not devoted much attention to the effects of specific forms of job crafting, particularly cognitive crafting. The present study builds on Conservation of Resources theory to explain how cognitive crafting might influence work meaningfulness for employees, and in turn, increase their experienced thriving at work. Moreover, we hypothesise that the impact of cognitive crafting on these outcomes is influenced by two motivational job characteristics: skill variety and job autonomy. To test our hypotheses, we collected three-wave survey data from 223 employees employed in a variety of occupations and industries in China. Results indicate that engaging in cognitive crafting enhances employees' work meaningfulness, resulting in thriving at work. Furthermore, skill variety and job autonomy are crucial moderators of these relationships. Specifically, when employees perceived low levels of skill variety or job autonomy, engaging in cognitive crafting was more likely to lead to enhanced work meaningfulness, which in turn resulted in higher levels of thriving at work. Implications for research, theory and practice are discussed.

Factors originating at the organizational, work, and individual levels are closely interrelated and intricately intertwined, affecting health rates. There was limited research on the interdependence and aggregate effects between multi-source factors and occupational health and well-being (OHW). It is challenging to achieve management goals. Therefore, considering cross-level factors and across the "work environment-stress-exposure-OHW" chain, individual vulnerability was considered. A Fuzzy Bayesian Belief Network (FBBN) driven by both domain knowledge and data was constructed to carve out the logic between multi-source factors and OHW. Workers from four coal mines were surveyed twice in 6 months. 714 valid samples were included in the analysis. The interdependencies among multi-source factors were identified by the Interpretive Structure Modeling method and the visual probability estimation was achieved based on FBBN. It revealed that the work and the organizational level were the root factors. Eight factors involved in work stress were mainly mediating, and actual exposure and individual vulnerability were direct factors. Pathway interventions and joint interventions were proposed. The prediction ability and scheme feasibility of FBBN were verified. The approach developed allows robust assessments of aggregate effects and obtains multi-source factor importance. This study provides vital insights and evaluation tools for understanding workplace stress and OHW management.

Stress forecasting is the cognitive process of anticipating and preparing to respond to future stress experiences based on one's own perceived future stress. Though it may seem intuitive that stress forecasting predicts stress, competing theories exist that indicate the relationship is not so inherent. In this paper we conducted two studies which both examine the relationships between stress forecasting and day stress, examining two different stress domains (appraisal and coping). Participants in Study 1 (n = 143 working adults) and Study 2 (n = 60 undergraduate students) completed 4 and 14 days, respectively, of ecological momentary assessment reports of stress appraisal forecasting, stress coping forecasting, stress appraisal reports, and stress coping reports, for a combined total of 5280 completed assessments. Exploratory analysis in Study 2 examined the importance of morning forecast discrepancy in relation to evening recalls of day stress. Results indicate that within domain (e.g., stress appraisal to appraisal reports), or domain specific, stress forecasting is predictive of day stress, and that across domains (e.g., stress appraisal to coping reports), or domain crossover, was consistent between stress appraisal forecasting and stress coping reports. Results suggest that magnitude of bias and day outlook (i.e., being either optimistic or pessimistic) about one's coping ability matters for day stress outcomes. Findings have implications for developing challenge-based thinking interventions and further understanding cognitive processes for building stress management strategies.

Prior to the COVID-19 pandemic, food insecurity and depression were growing public health concerns among graduate students. Yet, little is known about how COVID-19-related stressors exacerbated these health outcomes among graduate students. To address this research gap, this study examined two types of COVID-19-related stressors, anticipated concerns about remote learning and challenges interfering with academic and research responsibilities, in relation to food insecurity and depressive symptoms among public university graduate students. Between August and October 2020, 631 graduate students who utilised basic needs services from seven University of California campuses completed an online survey assessing the effects of COVID-19 on their academic experiences, mental health, and basic needs security. Regression analyses examined associations of COVID-19-related concerns and COVID-19-related challenges with food insecurity as well as COVID-19-related concerns and COVID-19-related challenges in relation to depressive symptoms. All four models were adjusted for age, sex, race and ethnicity, campus affiliation, and living with a partner. Models examining food security status as the dependent variable were adjusted for depressive symptoms and vice versa. Graduate students concerned about delayed graduation, post-graduate employment, isolation from faculty and not having access to healthcare reported higher counts of depressive symptoms. Challenges associated with higher counts of depressive symptoms included caring for family more than usual, spending more time on errands and not paying for utilities in full. Students concerned about accessing healthcare had higher odds of experiencing food insecurity. Challenges associated with food insecurity included spending more time on errands, being unable to afford housing and sending money to family members during the pandemic. Our findings illuminate the pandemic's deleterious consequences on graduate students' mental health and food security, underscoring the need for strong academic and basic needs programs and policies.

This study aimed to examine attachment and adult separation anxiety (ASA) among women who lost a parent in their youth. We hypothesized that insecure attachment and increased ASA from a romantic partner would be found among women who have lost a parent in youth, compared to women whose parents were both alive. Sixty women who lost one or both parents in their youth and 60 who had living parents participated in the study (mean age: 32.3, range: 18-62 years). Participants filled out the ASA and Short Attachment questionnaires. Women who lost a parent reported higher levels of anxious attachment and ASA from partner; the two groups did not differ, however, in terms of avoidant attachment. Additionally, similar effects on ASA and attachment were found among adult women who lost a father or a mother in their youth. In conclusion, the loss of a parent early in life may be associated with an insecure attachment style and increased ASA.
