RESUMO
The FERONIA (FER)-LLG1 co-receptor and its peptide ligand RALF regulate myriad processes for plant growth and survival. Focusing on signal-induced cell surface responses, we discovered that intrinsically disordered RALF triggers clustering and endocytosis of its cognate receptors and FER- and LLG1-dependent endocytosis of non-cognate regulators of diverse processes, thus capable of broadly impacting downstream responses. RALF, however, remains extracellular. We demonstrate that RALF binds the cell wall polysaccharide pectin. They phase separate and recruit FER and LLG1 into pectin-RALF-FER-LLG1 condensates to initiate RALF-triggered cell surface responses. We show further that two frequently encountered environmental challenges, elevated salt and temperature, trigger RALF-pectin phase separation, promiscuous receptor clustering and massive endocytosis, and that this process is crucial for recovery from stress-induced growth attenuation. Our results support that RALF-pectin phase separation mediates an exoskeletal mechanism to broadly activate FER-LLG1-dependent cell surface responses to mediate the global role of FER in plant growth and survival.

The question of how the brain links behavioral and biological features of defensive responses has remained elusive. The importance of this problem is underscored by the observation that behavioral passivity in stress coping is associated with elevations in glucocorticoid hormones, and each may carry risks for susceptibility to a host of stress-related diseases. Past work implicates the medial prefrontal cortex (mPFC) in the top-down regulation of stress-related behaviors; however, it is unknown whether such changes have the capacity to buffer against the longer-lasting biological consequences associated with aversive experiences. Using the shock probe defensive burying test in rats to naturalistically measure behavioral and endocrine features of coping, we observed that the active behavioral component of stress coping is associated with increases in activity along a circuit involving the caudal mPFC and midbrain dorsolateral periaqueductal gray (PAG). Optogenetic manipulations of the caudal mPFC-to-dorsolateral PAG pathway bidirectionally modulated active (escape and defensive burying) behaviors, distinct from a rostral mPFC-ventrolateral PAG circuit that instead limited passive (immobility) behavior. Strikingly, under conditions that biased rats toward a passive coping response set, including exaggerated stress hormonal output and increased immobility, excitation of the caudal mPFC-dorsolateral PAG projection significantly attenuated each of these features. These results lend insight into how the brain coordinates response features to overcome passive coping and may be of importance for understanding how activated neural systems promote stress resilience.

Hormonal contraceptives, including oral contraceptives (OCs), regulate hormonal cycles and broadly affect physiological processes, including stress responsivity. Whereas many users describe overall improved mood, up to 10 % of OC users experience adverse effects, including depression and anxiety. Given the link between regulation of hypothalamic-pituitary-adrenal (HPA) axis, stress exposure, and risk for depression, it is likely that OC-effects on stress mediate increased risk or increased resilience to these disorders. In this study, we developed and characterized a tractable mouse model of OC exposure with which to identify the mechanisms underlying OC modulation of brain, behavior, and mood. Specifically, we aimed to determine whether translationally relevant doses of OC-hormones in mice mimic changes in stress responsivity observed in humans taking OCs and describe behavioral changes during OC exposure. Young adult female C57Bl/6 N mice received daily ethinyl estradiol (EE) and levonorgestrel (LVNG) in 10 % sucrose, EE and drospirenone (DRSP) in 10 % sucrose, or 10 % sucrose alone. Translationally relevant doses of EE + LVNG-exposure, but not EE + DRSP, suppressed the acute stress response, consistent with effects observed in human OC users. EE + LVNG caused a specific anhedonia-like effect, without broad changes in stress-coping behavior, other depression-like behaviors, or anxiety-like behaviors. The suppression of regular estrous cycling, together with the blunting of the corticosterone response to acute stress, demonstrate the utility of this model for future studies to identify the mechanisms underlying OC interactions with stress, motivation, and risk for depression.

BACKGROUND: Given the increasing stress levels among medical students due to the impact of COVID-19, it is crucial to effectively reduce their stress levels for their future development. To better understand medical students' stress coping, this study investigated how their emotional intelligence is related to stress coping and whether this relationship is moderated by gender differences. METHODS: A cross-sectional study was conducted. A random sample of 744 medical students from Hebei Province, China, was investigated via an emotional intelligence scale and stress coping questionnaire from March-May 2023. The response rate was 93%. SPSS and Mplus statistical software were used for the data analysis. RESULTS: The self-emotional appraisal of medical students had a significant negative effect on avoidant coping (ß = -0.173, CI 95% = [-0.243, -0.099], p < .001). However, the other dimensions of emotional intelligence (others' emotional appraisal, use of emotion, and regulation of emotion) had a significant positive impact on the active coping of female medical students (ß = 0.146, CI 95% = [0.082,0.214], p < .001; ß = 0.235, CI 95% = [0.167,0.304], p < .001; ß = 0.165, CI 95% = [0.084,0.247], p < .001). In contrast to those of female medical students, other dimensions of emotional intelligence had a significant positive impact on the avoidant coping of male medical students (ß = -0.161, CI 95% = [-0.284, -0.062]; p < 0.01; ß = 0.126, CI 95% = [0.043,0.246], p < 0.001; ß = 0.159, CI 95% = [0.054,0.277], p < 0.05; ß = -0.221, CI 95% = [-0.363, -0.129], p < 0.001). Moreover, the use of emotion had a significant positive impact on the active coping of male medical students (ß = 0.272, CI 95% = [0.182,0.382], p < .001). Furthermore, gender differences had a moderating effect on the relationship between emotional intelligence dimensions and stress coping (ß = 0.178; CI 95% = [0.068,0.292]; p < 0.05). Others' emotional appraisal has a greater impact on female students' active coping. In addition, with increasing regulation of emotion ability, female medical students reduce avoidant coping (ß = 0.169, CI 95% = [0.002,0.326]; p < 0.05). CONCLUSIONS: The current study revealed that gender is a significant moderator of the relationship between medical students' emotional intelligence and stress coping. These findings may help medical colleges focus on gender differences when improving medical students' ability to cope with stress.

The purpose of this descriptive-exploratory study was to identify profiles of mental health among undergraduate nursing students to understand the relationship between student's mental health profiles and relevant risk and protective factors at the onset of COVID-19. Latent Class Analysis (LCA) was employed to cull these students' mental health profiles (yielding 3 profiles) using data collected from 277 participants enrolled in a four-year BSN Program at a large, public institution in the Southeastern United States. Relational analyses of these profiles indicated that students who were the most vulnerable for mental health challenges also had the highest resilience and coping scores.

BACKGROUND: The sleep quality of nurses affects both their health and standard of nursing care. Working conditions, depression, and coping potential can also lead to sleep problems. INTRODUCTION: Sleep plays a crucial role in overall health at every stage of life. The purpose of this study is to determine the effect of sleep quality, depression, and coping mechanisms on the performance of nurses, whose sleep quality is strongly affected due to shift-based work. METHODS: The sample of this descriptive correlational study consisted of 133 healthcare workers. Data were collected using the Personal Information Form, Beck Depression Inventory (BDI), Coping Response Inventory (CRI), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS) and evaluated using the t test, Mann-Whitney U test, one-way ANOVA, Enter method, and linear regression. FINDINGS: One in three nurses reported having poor-quality sleep, and one in two nurses said they felt sleepy during the day. With declining sleep quality, the nurses' ability to cope with stress diminished, and their degree of depression increased. DISCUSSION: The nurses' financial situation and level of depression were key factors that influenced their quality of sleep and capacity to handle stress. To improve nurses' sleep, the shift pattern needs to change. CONCLUSION: To increase the quantity of sleep and enhance mental health, changes should be made to the shift schedules of nurses to allow for appropriate rest and reduce daytime sleepiness. IMPLICATIONS FOR NURSING PRACTICE AND POLICIES: Improved working conditions for nurses and updated nursing standards are required to improve nurses health and wellbeng.
RESUMO
Stress-coping strategies have been implicated in depression. The control of stress coping may improve the symptom and higher prevalence of depression during the postpartum period in women. However, the neuronal mechanisms underlying stress coping remain to be fully elucidated in postpartum women. In this study, we examined how locus coeruleus-noradrenergic (LC-NA) neurons, which have been associated with both stress coping and depression, regulate changes in coping style induced by subchronic exposure to unfamiliar male mice as a social threat in postpartum female mice. In contrast to virgin females, dams exposed to unfamiliar males daily for four consecutive days showed reduced immobility duration in the forced swim test, indicating that exposure to unfamiliar males decreased passive stress coping in dams. Exposure to unfamiliar males also decreased sucrose palatability in the sucrose preference test and suppressed the crouching behavior in the maternal care test but did not affect anxiety-like behavior in the hole-board test in dams. In fiber photometry analyses, LC-NA neurons showed differential activity between dams and virgin females in response to unfamiliar males. Chemogenetic inhibition of LC-NA neurons during exposure to unfamiliar males prevented the social threat-induced decrease in immobility duration in the forced swim test in dams. Furthermore, inhibition or activation of LC-NA neurons exacerbated crouching behavior in dams. These results indicate that LC-NA neurons regulate the social threat-induced decrease in passive stress coping and relieve social threat-induced inhibition of maternal care in postpartum female mice.

BACKGROUND: Stress coping strategies are related to health outcomes. However, there is no clear evidence for sex differences between stress-coping strategies and mortality. We investigated the relationship between all-cause mortality and stress-coping strategies, focusing on sex differences among Japanese adults. METHODS: A total of 79,580 individuals aged 35-69 years participated in the Japan Multi-Institutional Collaborative Cohort Study between 2004 and 2014 and were followed up for mortality. The frequency of use of the five coping strategies was assessed using a questionnaire. Sex-specific, multivariable-adjusted hazard ratios (HRs) for using each coping strategy ("sometimes," and "often/very often" use versus "very few" use) were computed for all-cause mortality. Furthermore, relationships were analyzed in specific follow-up periods when the proportion assumption was violated. RESULTS: During the follow-up (median: 8.5 years), 1,861 mortalities were recorded. In women, three coping strategies were related to lower total mortality. The HRs for "sometimes" were 0.81 (95% confidence interval [CI], 0.67-0.97) for emotional expression, 0.79 (95% CI, 0.66-0.95) for emotional support-seeking, and 0.80 (95% CI, 0.66-0.98) for disengagement. Men who "sometimes" used emotional expression and sometimes or often used problem-solving and positive reappraisal had a 15-41% lower HRs for all-cause mortality. However, those relationships were dependent on the follow-up period. There was evidence that sex modified the relationships between emotional support-seeking and all-cause mortality (P for interaction = 0.03). CONCLUSION: In a large Japanese sample, selected coping strategies were associated with all-cause mortality. The relationship of emotional support-seeking was different between men and women.

BACKGROUND: Children with long-term conditions are vulnerable due to the treatments required for their conditions. Since the start of the coronavirus disease 2019 (COVID-19) pandemic, Western Australians experienced restrictions that changed daily life activities but were able to return to some of their previous routines due to the restrictions. AIM: The study explored the stress experiences of parents caring for children with long-term conditions during COVID-19 in Western Australia. DESIGN AND PARTICIPANTS: The study was codesigned with a parent representative caring for children with long-term conditions to ensure essential questions were targeted. Twelve parents of children with various long-term conditions were recruited. Ten parents completed the qualitative proforma, and two parents were interviewed in November 2020. Interviews were audio-recorded and transcribed verbatim. Data were anonymised and analysed using reflexive thematic analysis. FINDINGS: Two themes were produced: (1) 'Keep my child safe' describes the children's vulnerabilities due to their long-term conditions, the adjustments parents' made to keep their children safe and the various consequences faced. (2) 'COVID-19's silver lining' covers the positives of the COVID-19 pandemic, including their children having fewer infections, the availability of telehealth appointments, relationship improvements and the parent's hopes for a new normal where behaviours prevent transmission of infectious (e.g., hand sanitising). CONCLUSION: Western Australia provided a unique context for the COVID-19 pandemic due to no transmission of the virus severe acute respiratory syndrome coronavirus 2 at the time of the study. The tend and befriend theory aids in explaining the parents' stress experiences, and the application highlights a unique aspect of this theory. Parents tended to their children during COVID-19, but many could no longer rely on others for connection, support and respite, and became further isolated in attempting to protect their children due to COVID-19 consequences. The findings highlight that some parents of children with long-term conditions need specific attention during times of pandemics. Further review is recommended to support parents through the impact of COVID-19 and similar crises. PATIENT OR PUBLIC CONTRIBUTION: This study was codesigned with an experienced parent representative who was part of the research team and involved throughout the research process to ensure meaningful end-user engagement and ensure essential questions and priorities were addressed.

Kinship care represents the most prevalent form of foster care in Poland. Most commonly, the role of kinship carers is taken on by grandparents, who may struggle with various problems, needs and deficits in this role. The aim of this study was to investigate the problem of patience in kinship carers aged 60 + and its impact on deficits in the performance of roles and duties.Methods Seventy-five foster grandparents (63 female, 84%) aged from 61 to 97 years (M = 69,12; SD = 6.22) were investigated in north-western Poland in 2018 and 2019. The study was based on the diagnostic survey method.Results Psychological disposition, functioning, health problems and parental needs and deficits were assessed using standardised psychometric scales and tools self-constructed for this research study. A lack of patience with foster children was reported by 46.7% (n = 35) of the respondents. Patience deficits corresponded with a significantly lower sense of coherence, especially in the manageability domain (p < 0.001) and such stress coping strategies as lower positive reappraisal (p = 0.016) and seeking of emotional support (p = 0.025), as well as a greater tendency for suppression of activities (p = 0.014) and venting of emotions (p = 0.035). Relatively permanent personality traits and general self-efficacy were not differentiated by patience with children.Conclusions The results suggest that patience - so important for biological and foster parents - is related to psychological competencies that can be improved through psychoeducation and skills-training, which may be beneficial for improving foster carers' effectiveness.

INTRODUCTION: The number of young adults with eating disorders or subthreshold eating disorders has increased recently. Although disordered eating behaviors persist once they appear, there have been relatively few studies on factors that might cause disordered eating behaviors. The purpose of this study was to investigate how the eating attitudes of young adults change over time and the risk factors that increase disordered eating behaviors. METHODS: A total of 1,141 college students, 639 males and 502 females, participated. We investigated changes in eating attitudes (using EAT-26 and BITE), depressive symptoms (using BDI-II), and stress coping (using CISS, which has three subscales) between 2 time points: at college entrance and in the fourth year of college. We divided the students into three groups (clinical, subthreshold, and healthy) based on EAT-26 scores and compared their BDI-II and CISS scores. Next, we identified students who developed disordered eating behaviors, both clinical and subthreshold, during their time at college (exacerbated students) and compared depressive symptoms and stress coping styles between exacerbated students and healthy students (unchanged students). RESULTS: The students in the subthreshold group (both males and females) scored significantly higher on the BDI-II and emotion-oriented coping (CISS-E) than the students in the healthy group at college entrance. Additionally, the exacerbated students (both males and females) scored significantly higher on the CISS-E in the fourth year than unchanged students. The female exacerbated students scored significantly higher on the BDI-II than female unchanged students at both time points. CONCLUSIONS: Our results show that depressive symptoms and nonadaptive stress coping are associated with an increased risk of disordered eating behaviors. This study suggests that early intervention may be necessary for both the clinical and subthreshold groups. The key to early intervention may be to manage not only eating behaviors but also depressive symptoms and stress coping.

Prenatal manipulations can lead to neurobehavioral changes in the offspring. In this study, individual and combined effects of forced exercise and zinc supplementation during pregnancy on prenatally restraint stress (PRS)-induced behavioral impairments, neuro-inflammatory responses, and oxidative stress have been investigated in adolescent female rat offspring. Pregnant rats were divided into five groups: control; restraint stress (RS); RS + exercise stress (RS + ES), RS + zinc supplementation (RS + Zn); and RS + ES + Zn. All the pregnant rats (except control) were exposed to RS from gestational days 15 to 19. Pregnant rats in ES groups were subjected to forced treadmill exercise (30 min/daily), and in Zn groups to zinc sulfate (30 mg/kg/orally), throughout the pregnancy. At postnatal days 25-27, anxiety-like and stress-coping behaviors were recorded, and the gene expressions of interleukin-1ß (IL-1ß) and tumor necrosis factor-α (TNF-α) and the concentration of total antioxidant capacity were measured in the prefrontal cortex. PRS significantly enhanced anxiety, generated passive coping behaviors, increased IL-1ß and TNF-α expression, and decreased the antioxidant capacity. ES potentiated while zinc reversed PRS-induced behavioral impairments. Prenatal zinc also restored the anti-inflammatory and antioxidant capacity but had no effect on additive responses imposed by the combination of RS and ES. Suppression of PRS-induced behavioral and neurobiological impairments by zinc suggests the probable clinical importance of zinc on PRS-induced changes on child temperament.

BACKGROUND: Over recent decades, chronic stress at an early age has become a worrying health problem in children. We seek to evaluate an intervention involving mindfulness-based practices and prosocial activities in 7- to 8-year-old children. METHODS: Stress levels were determined using hair cortisol concentration (HCC), and social integration was measured by means of a sociogram. The program had previously proven to be effective in decreasing salivary cortisol levels and in favouring social integration in children. A total of 35 children participated in the study: 18 constituted the intervention group and 17 the wait-list group. In both groups, HCC and social integration were evaluated before and after the intervention conducted throughout an entire school year. RESULTS: The experimental group showed a significant reduction in HCC, as well as significant enhancement of social integration levels, whereas no changes were observed in the wait-list group. CONCLUSIONS: This is the first research to show that HCC, a reliable neuroendocrine indicator, decreased as a result of a mindfulness-based program. This successful outcome adds new evidence to previous findings regarding the reduction of chronic stress in children following participation in this program.

An escapable (ES)/inescapable stress (IS) paradigm was used to study whether behavioral control and repeated footshock stressors may affect adult neurogenesis and related cognitive function. Male stressed mice having behavioral control (ES) had a short-term escalation in dorsal dentate gyrus (DG) neurogenesis, while similarly stressed mice having no such control had unaltered neurogenesis as compared to control mice receiving no stressors. Paradoxically, ES and IS mice had comparable stress-induced corticosterone elevations throughout the stress regimen. Appetitive operant conditioning and forced running procedures were used to model learning and exercise effects in this escapable/inescapable paradigm. Further, conditioning and running procedures did not seem to affect the mice's corticosterone or short-term neurogenesis. ES and IS mice did not show noticeable long-term changes in their dorsal DG neurogenesis, gliogenesis, local neuronal density, apoptosis, autophagic flux, or heterotypic stress responses. ES mice were found to have a greater number of previously labeled and functionally integrated DG neurons as compared to IS and control mice 6 weeks after the conclusion of the stressor regimen. Likewise, ES mice outperformed IS and non-stressed control mice for the first two, but not the remaining two, trials in the object location task. Compared to non-stressed controls, temozolomide-treated ES and IS mice having a lower number of dorsal DG 6-week-old neurons display poor performance in their object location working memory. These results, taken together, prompt us to conclude that repeated stressors, albeit their corticosterone secretion-stimulating effect, do not necessary affect adult dorsal DG neurogenesis. Moreover, stressed animals having behavioral control may display adult neurogenesis escalation in the dorsal DG. Furthermore, the number of 6-week-old and functionally-integrated neurons in the dorsal DG seems to confer the quality of spatial location working memory. Finally, these 6-week-old, adult-born neurons seem to contribute spatial location memory in a use-dependent manner.

The COVID-19 pandemic severely hit the hospitality industry and caused employees concerns over health, finance, and well-being. These challenges may trigger their decisions to leave the profession, leading to major talent crises in the industry. Guided by the transactional model of stress and coping and the career construction theory, this study explored how their experiences with the pandemic affected their career choices moving on. A phenomenological approach was adopted, and 31 current and past hospitality employees were interviewed. The findings supported the conceptual model and addressed the connection between stress management and career decisions among the participants. It is also noted that, besides generational differences, most participants' career decisions at this critical moment were influenced by their personality traits, industry involvement, and employer-employee relationships. Thus, to create a sustainable, resilient, and engaged workforce, hospitality practitioners must commit to crafting positive relationships with their employees both in regular and crisis times.
RESUMO
This study aimed to determine the correlation between stress coping styles and self-efficacy with regard to the spiritual and religious coping of mothers with disabled children. The descriptive and relational screening model was used in this study. The research was completed with 227 mothers in a private rehabilitation center at Turkey. The data were collected using Maternal Spiritual Coping, Religious Coping Styles, Stress Coping Styles Scales (SCSS), and General Self-Efficacy Scales. As a result of the study, there was a statistically advanced degree of significant correlation in a positive direction between effective coping with stress and spiritual coping (p < 0.001), and a negative significant correlation between ineffective coping with stress and general self-efficacy (p < 0.05). Additionally, there was a negative significant correlation between the SCSS-effective coping dimension with the SCSS-ineffective coping points (p < 0.05). The high level of spiritual coping of mothers and its effect on coping with stress is an important result. For the participation of children with disabilities and their parents in society, it is essential to identify components such as mental health and spiritual coping that will improve mothers' mental health so that mothers can effectively cope with the difficulties they experience.

The reported high rates of deaths and negative psychological outcomes of the Coronavirus (COVID-19) pandemic have led to an increased empirical interest in examining the contributing factors of coping during the COVID-19 pandemic. Adolescents living in Arab societies have unique challenges that may increase the likelihood of exhibiting symptoms of stress during this crisis. However, this population has been understudied in this context. The current research aims to elucidate factors that may contribute to Arab Israeli-Palestinian students' coping abilities during the COVID-19 pandemic by investigating the relationship between coping with stress during the COVID-19 outbreak and both self-control and religiosity. To our knowledge, the present study is the first to investigate the relationship of coping with stress during the COVID-19 outbreak with self-control skills and religiosity among Arab Israeli-Palestinian college students in Israel (n = 465). Correlational analyses and stepwise multiple regression models were used to examine these relationships. The stepwise multiple regression model demonstrated that (1) higher levels of self-control (ß = .19, p < .01) and religiosity (ß = .16, p < .01) predicted higher levels of adaptive, problem-focused coping, and (2) higher levels of self-control (ß = -.21, p < .01) and religiosity (ß = -.17, p < .01) predicted lower levels of maladaptive, emotion-focused coping. Thus, the current research demonstrates the importance of these variables in countering stress resulting from the COVID-19 outbreak in non-Western societies. These findings are consistent with previous literature that has addressed the impact of self-control and religiosity in improving coping behaviours in Western societies.

Introduction: This paper presents the role of attachment style in determining an individual's way of coping with stress, which in turn helps to understand the differences in response and adjustment to cancer among cancer patients. Cancer is an illness that causes overwhelming distress, and dealing with it requires social support, among other coping strategies. Material and methods: Studies show that social support is associated with a decrease in psychological symptoms and a better quality of life in cancer patients. According to attachment theory, one's perception of threat, way of signaling distress, and strategies of coping with it, with special consideration for the ability to use a partner's support, relies on differences in avoidance and anxiety (attachment style dimensions). Results: People with high avoidance (associated with deactivating attachment strategy) tend not to seek support from others and rely on themselves. Conclusions: People with high anxiety (associated with deactivating attachment strategy) tend to display strong emotional responses, permanently seek attention and support from others, and yet are less able to feel comforted by them.
RESUMO
Dominance-based social hierarchies are common among teleost fishes. The rank of an animal greatly affects its behaviour, physiology and development. The outcome of fights for social dominance is affected by heritable factors and previous social experience. Divergent stress-coping styles have been demonstrated in a large number of teleosts, and fish displaying a proactive coping style have an advantage in fights for social dominance. Coping style has heritable components, but it appears to be largely determined by environmental factors, especially social experience. Agonistic behaviour is controlled by the brain's social decision-making network, and its monoaminergic systems play important roles in modifying the activity of this neuronal network. In this Review, we discuss the development of dominance hierarchies, how social rank is signalled through visual and chemical cues, and the neurobiological mechanisms controlling or correlating with agonistic behaviour. We also consider the effects of social interactions on the welfare of fish reared in captivity.

BACKGROUND: Eating plays an important role in mental and physical health and is influenced by affective (e.g., emotions, stress) and appetitive (i.e., food craving, hunger) states, among others. Yet, substantial temporal variability and marked individual differences in these relationships have been reported. Exploratory data analytical approaches that account for variability between and within individuals might benefit respective theory development and subsequent confirmatory studies. METHODS: Across 2 weeks, 115 individuals (83% female) reported on momentary affective states, hunger, and food craving six times a day. Based on these ecological momentary assessment (EMA) data we investigated whether latent class vector-autoregression (LCVAR) can identify different clusters of participants based on similarities in their temporal associations between these states. RESULTS: LCVAR allocated participants into three distinct clusters. Within clusters, we found both positive and negative associations between affective states and hunger/food craving, which further varied temporally across lags. Associations between hunger/food craving and subsequent affective states were more pronounced than vice versa. Clusters differed on eating-related traits such as stress-eating and food craving as well as on EMA completion rates. DISCUSSION: LCVAR provides novel opportunities to analyse time-series data in affective science and eating behaviour research and uncovers that traditional models of affect-eating relationships might be overly simplistic. Temporal associations differ between subgroups of individuals with specific links to eating-related traits. Moreover, even within subgroups, differences in associations across time and specific affective states can be observed. To account for this high degree of variability, future research and theories should consider individual differences in direction and time lag of associations between affective states and eating behaviour, daytime and specific affective states. In addition to that, methodological implications for EMA research are discussed.
