Human hair cortisol concentration (HCC) has previously been found to be highly stable for a 1-year interval (r = 0.73) in terms of a product-moment correlation. The present study aimed to replicate this finding and compare HCC stability regarding 1-year and 2-year test-retest intervals. Female university students (N = 39) provided hair strands twice (t1 and t2) at intervals of 1 (n = 21) or 2 years (n = 18). Multiple regression analysis predicting HCC at t2 revealed a significant interaction term (HCC at t1 × time interval condition). It was determined that HCCs were substantially related for the 1-year interval but unrelated for the 2-year interval. The findings were not attributable to potential influences, such as hair treatment. The product-moment correlation showed nearly identical consistency with previous research regarding the 1-year test-retest interval. There was no significant product-moment correlation for the 2-year interval. Overall, these findings indicate that within a temporal framework of 1 year, HCCs may be stable predictors in correlational studies where the focus is on the rank orders of measured values.

Effective regulation of emotions is essential in coping with everyday stressors. Although cognitive reappraisal and acceptance are both commonly employed to downregulate negative emotions, they differ in many aspects. Their effectiveness in real-life situations can also be influenced by prior stress or a person's trait preferences for certain emotion regulation (ER) strategies. In the present study, we compared the effectiveness of both ER strategies in a laboratory setting, while focussing on the effect of stress and trait moderators. Ninety-eight healthy participants aged 18-40 were randomly divided into three groups with instructions to use reappraisal, acceptance, or nothing while viewing distressing pictures from the IAPS database. Half of the participants in each group underwent a laboratory stressor (socially evaluated cold pressor test) 20-30 min before the ER task. The effectiveness of ER was measured subjectively on the visual analog scale, and by measuring heart rate, skin conductance, and pupil responses. The data show that cognitive reappraisal lowered subjectively experienced negative emotion, while acceptance did not. These group differences were however not supported by psychophysiological indicators. Secondly, although the laboratory stressor elicited cortisol stress responses in our participants, we did not find any effect on ER. Furthermore, the data has not supported the moderation effect by trait reappraisal and acceptance. The present findings show that deliberate usage of ER strategies when viewing emotionally charged pictures leads to a decrease in experienced emotion. On the other hand, the effects of stress and trait moderators were not supported, therefore they may be smaller and more variable than expected.

Child externalising problems, such as acting out and hostility, have been found to be significant stressors for parents, leading to increased distress levels. This cross-sectional study examined the mediating role of parents' use of mobile phones to soothe or engage children in the association between child externalising problems and distress in parents. Altogether 937 parents of children aged 5-12 reported their child's externalising problems, child's mobile phone use, and their distress through an online survey. The findings indicated that parents of children with high externalising problems are more likely to use mobile phones to soothe their children and keep them engaged in daily activities, which, in turn, is associated with higher distress in parents. Child externalising problems and distress in parents remained significantly and positively associated even after accounting for the mediating effect. The results highlight the child-driven effect on distress in parents through parenting behaviours, indicating the importance of providing alternative parenting strategies to cope with child externalising behaviours, in order to promote parental emotional well-being.

Although stress is often related to substance use, it remains unclear whether substance use is related to individual differences in how adolescents respond to stress. Therefore the present study examined associations between substance use and daily emotional reactivity to stress within a year across adolescence. Adolescents (N = 330; Mage = 16.40, SD = 0.74 at study entry; n = 186 female; n = 138 Latine; n = 101 European American; n = 72 Asian American; n = 19 identifying as another ethnicity including African American and Middle Eastern) completed a longitudinal study, including three assessments between the 10th grade and 3-years post-high school. At each assessment, participants reported frequency of alcohol and cannabis use and the number of substances they had ever used. They also completed 15 daily checklists, in which they reported the number of daily arguments and their daily emotion. Multilevel models suggested that more frequent alcohol and cannabis use were related to attenuated positive emotional reactivity to daily stress (i.e., smaller declines in positive emotion on days when they experienced more arguments) for both male and female adolescents. Associations for negative emotional reactivity to stress varied by sex; more frequent alcohol use and use of more substances in one's lifetime were related to greater anxious emotional reactivity to stress among female adolescents, whereas more frequent alcohol and cannabis use and higher lifetime substance use were related to attenuated depressive emotional reactivity to stress among male adolescents. Taken together, substance use was related to emotional reactivity to daily stress within the same year during adolescence, although associations differed by valence and adolescent sex.

Healthcare professionals report poor overall well-being, with many citing mental health concerns and stress as contributing factors. Given that healthcare professionals are crucial to the sustainability of the health sector, examining the factors affecting their well-being at work is essential. This paper reports the findings of research conducted in an Australian regional public hospital, utilising the conservation of resources theory to examine the factors (similarities and differences) that influence the resource loss of healthcare professionals (nurses, medical professionals, and allied health professionals). Qualitative semi-structured interviews were conducted with 43 healthcare professionals of varying roles, and participant perspectives revealed two themes contributing to a resource-poor work environment: 'occupational demands and obstacles' and 'barriers to effective teams'. These challenges caused individual resource loss, and as stress arises from resource depletion, each turn of the stress spiral left the individuals and organization with fewer resources to counteract the loss, causing loss spirals to intensify in momentum and scale. The findings of this research emphasise the importance of executing a proactive approach to well-being initiative implementation to support resource investment and assist in creating a more nurturing healthcare work environment that fosters resource creation and sustenance for healthcare professionals.

We surveyed workers in the performing arts sector to explore the role of positive mindsets in facilitating work-related resilience, engagement and reduced stress using retrospective reporting surveys during the Covid-19 work shut down period. Integrating conservation of resources theory with research on metacognitive self-regulation, we controlled for the severity of the Covid-19 impact and negative affect and found that hope (but not mindfulness) predicted professional engagement, resiliency and reduced tension and distress over time. Further, the relationships between hope and outcomes were mediated by positive affect (PA). Mindfulness was not indirectly (via PA) related to outcomes (i.e., engagement, resiliency, job tension, distress) but was directly and negatively related to job tension and distress. These findings suggest that in times of intense stress or adversity, future-oriented thinking such as hope may be more effective than mindfulness in sustaining positive mindsets and action-oriented outcomes such as engagement. Implications for practice and future research are discussed.

In their seminal Transactional Theory of Stress, Lazarus and Folkman described a complex adaptation mechanism that involves appraisal and coping processes that lead to the subjective experience of stress. In this study, we examined the temporal order of all components of this theory using a cross-lagged panel analysis. A sample of 354 students (62.10% female, mean age = 20.63 y.o.) participated in a 5-week study and completed weekly self-reported measures of prospective appraisal, coping, core burnout, and mental health (i.e. depression, anxiety, and stress). Using cross-lagged panel network analyses, we analyzed how each measured variable is predicted by all variables from the previous measurement moment. Convergent with the transactional stress theory, we found that threat appraisals and negative self-perception predicted future anxiety and depression. Contrary to expectations, core burnout and somatization emerged as significant predictors of poor mental health outcomes, suggesting a self-perpetuating spiral. Furthermore, our study highlighted the importance of recognizing the bidirectional connections between appraisals, coping strategies, and mental well-being.

Depression is closely related to individual social functions. The current study aimed to examine whether depression is associated with ostracism, whether interpretation bias mediates this relationship, and whether trait mindfulness moderates direct and indirect relationships between depression and ostracism. Overall, 389 Chinese college students completed the Center for Epidemiological Survey, Depression Scale, Interpretation Bias Questionnaire, Philadelphia mindfulness scale, and perceived ostracism scale at two-time points. Latent Profile analysis and moderated mediation analysis were performed. After controlling for sex and age, depression (t1) was positively correlated to perceived ostracism, with this relationship being partially mediated by negative interpretation bias (IBN, t2). The effect of IBN on perceived ostracism was weak when awareness was high at time 2. Acceptance had a non-significant moderating role in the relationship between IBN and perceived ostracism at time 2. LPA delineated three profiles: high awareness, high acceptance, and medium mindfulness. The moderating role of the different profiles in the relationship between IBN (t2) and perceived ostracism (t2) was significant. Depressed individuals appear to experience more ostracism because of IBN. Awareness might alleviate the effect of IBN on perceived ostracism.

Against the background of Job Demands-Resources and Conservation of Resources theory and research on organizational communication, this prospective study among n = 312 employees explores the significant role of perceived information process quality (PIPQ) in enhancing employees' optimism during the COVID-19 pandemic. It thereby contributes to a deeper understanding of the factors influencing employee optimism in challenging contexts. In this study, PIPQ is defined by the availability of timely information, clarity, and consistency in the information provided. Results from latent change score modelling revealed that employees who experienced high PIPQ, particularly consistent information, reported feeling more optimistic about work-related aspects and also experienced spillover effects into their private lives. Notably, both consistency in information prior to the pandemic and increases in consistent information during the pandemic demonstrated this beneficial effect. Moreover, timely available information also positively influenced optimism, especially regarding work-related aspects. However, the study did not find evidence that clarity in information significantly affected optimism. In summary, the findings underscore the importance of accessible and consistent information as a vital resource for employees' ability to navigate crises.

Purpose in life is an aspect of well-being associated with less subjective stress. The present research sought to expand this literature by testing the association between both dispositional and momentary purpose with stress in daily life using a micro-longitudinal study design. Participants (N = 303) reported their dispositional purpose at baseline and reported their momentary purpose and stress three times a day for 8 days. Between-person, dispositional purpose was associated with less momentary stress across the 8 days tested with linear regression (β = -0.29, 95% CI = -0.39, -18, p < 0.001); it was unrelated to variability in stress (β = 0.05, 95% CI = -0.05, 0.14, p = 0.310). In contrast, the within-person analysis tested with multilevel modelling indicated that in moments when participants felt more purpose-driven than their average, they felt more stressed (b = 0.09, 95% CI = 0.06, 0.12, SE = 0.01, p < 0.001). This association was slightly stronger among participants with relatively lower dispositional purpose (b_interaction = -0.04, SE = 0.02, 95% CI = -0.08, -0.01, p = 0.032). This study replicated the negative association between dispositional purpose and subjective stress when stress was measured at moments in daily life. It also found that feeling more purpose-driven than usual in the moment is stressful, a counterintuitive finding that, if replicated, suggests that striving for purpose can be stressful in the moment, even if feeling more purposeful in general is associated with lower stress.
