Perinatal posttraumatic stress disorder as a predictor of mother-child bonding quality 8 months after childbirth: a longitudinal study.

BACKGROUND: Negative childbirth experiences can be related to the onset of perinatal post-traumatic stress symptomatology (P-PTSS), which significantly impacts the mother and the infant. As a response in the face of the discomfort caused by P-PTSS, maladaptive emotion regulation strategies such as brooding can emerge, contributing to the consolidation of post-partum depressive symptoms. Ultimately, both types of symptomatology, P-PTSS and post-partum depression, can act as risk factors for developing mother-child bonding difficulties. Still, this full set of temporal paths has to date remained untested. The present longitudinal study aimed to analyze the risk factors associated with the appearance of P-PTSS after post-partum and to test a path model considering the role of P-PTSS as an indirect predictor of bonding difficulties at eight months of postpartum. METHODS: An initial sample of pregnant women in the third trimester of gestation (N = 594) participated in a longitudinal study comprising two follow-ups at two and eight months of postpartum. The mothers completed online evaluations that included socio-demographic data and measures of psychological variables. A two-step linear regression model was performed to assess the predictive role of the variables proposed as risk factors for P-PTSS, and a path model was formulated to test the pathways of influence of P-PTSS on bonding difficulties. RESULTS: A history of psychopathology of the mother, the presence of depression during pregnancy, the presence of medical complications in the mother, and the occurrence of traumatic birth experiences all acted as significant predictors of P-PTSS, explaining 29.5% of its variance. Furthermore, the path model tested further confirmed an indirect effect of P-PTSS, triggered by a negative childbirth experience, on subsequent bonding difficulties eight months after labor through its association with higher levels of brooding and, ultimately, postpartum depression levels. A further path showed that bonding difficulties at two months postpartum can persist at eight months postpartum due to the onset of brooding and postpartum depression symptoms. CONCLUSION: We identified a set of robust predictors of P-PTSS: the mother's previous history of depression, perinatal depression during pregnancy, the presence of medical complications in the mother and the occurrence of traumatic birth experiences, which has important implications for prevention. This is particularly relevant, as P-PTSS, when triggered by a negative childbirth experience, further indirectly predicted the development of mother-child bonding difficulties through the mediation of higher use of brooding and symptoms of postpartum depression. These findings can serve as a basis for developing new longitudinal studies to further advance the understanding of perinatal mechanisms of mental health.

Effects of a Digital Mental Health Intervention on Perceived Stress and Rumination in Adolescents Aged 13 to 17 Years: Randomized Controlled Trial.

BACKGROUND: Although adolescents report high levels of stress, they report engaging in few stress management techniques. Consequently, developing effective and targeted programs to help address this transdiagnostic risk factor in adolescence is particularly important. Most stress management programs for adolescents are delivered within schools, and the evidence for these programs is mixed, suggesting a need for alternative options for stress management among adolescents. OBJECTIVE: The aim of the study is to test the short-term effects of a self-guided digital mental health intervention (DMHI) designed for adolescents on perceived stress and rumination (ie, brooding). METHODS: This was a 12-week, 2-arm decentralized randomized controlled trial of adolescents aged 13 to 17 years who presented with elevated levels of perceived stress and brooding. Participants were randomly assigned to engage with a self-guided DMHI (Happify for Teens) or to a waitlist control. Participants assigned to the intervention group were given access to the program for 12 weeks. Happify for Teens consists of various evidence-based activities drawn from therapeutic modalities such as cognitive behavioral therapy, positive psychology, and mindfulness, which are then organized into several programs targeting specific areas of concern (eg, Stress Buster 101). Participants in the waitlist control received access to this product for 12 weeks upon completing the study. Participants in both groups completed measures of perceived stress, brooding, optimism, sleep disturbance, and loneliness at baseline, 4 weeks, 8 weeks, and 12 weeks. Changes in outcomes between the intervention and waitlist control groups were assessed using repeated-measures multilevel models. RESULTS: Of the 303 participants included in data analyses, 132 were assigned to the intervention and 171 to the waitlist. There were significantly greater improvements in the intervention condition for perceived stress (intervention: B=-1.50; 95% CI -1.82 to -1.19; P<.001 and control: B=-0.09; 95% CI -0.44 to 0.26; P=.61), brooding (intervention: B=-0.84; 95% CI -1.00 to -0.68; P<.001 and control: B=-0.30; 95% CI -0.47 to -0.12; P=.001), and loneliness (intervention: B=-0.96; 95% CI -1.2 to -0.73; P<.001 and control: B=-0.38; 95% CI: -0.64 to -0.12; P=.005) over the 12-week study period. Changes in optimism and sleep disturbance were not significantly different across groups (Ps≥.096). CONCLUSIONS: Happify for Teens was effective at reducing perceived stress, rumination, and loneliness among adolescents over 12 weeks when compared to a waitlist control group. Our data reveal the potential benefits of DMHIs for adolescents, which may present a more scalable, destigmatized, and cost-effective alternative to school-based programs.

Hard to let it go: repetitive negative thinking and hoarding in later life in Japan.

Objectives: Hoarding in older adults can have a detrimental effect on daily life. Repetitive negative thinking (RNT) could result in a greater avoidance of discarding and increased saving behaviors; yet, the unique role of RNT on hoarding in older adults remains understudied. This study aimed to investigate whether the intensity of RNT contributes to hoarding in older adults. Methods: Two hundred and sixty-four older adults in Japan (ages 65-86 years, 132 males and 132 females) participated in an online survey. Hierarchical regression analyses were conducted to examine whether RNT could significantly explain the variance of hoarding after controlling for age, sex, years of education, self-reported cognitive impairment, and depression. Results: As we expected, RNT was significantly associated with greater hoarding behaviors, such as excessive acquisition (ß = .27, p = .005) and difficulty in discarding (ß = .27, p = .003). On the other hand, reflection, repetitive thinking without negative emotional valence, was significantly associated with higher scores on clutter (ß = .36 p < .001). Conclusion: Our findings highlight the importance of addressing RNT in the prevention and treatment of hoarding symptoms among older adults, potentially leading to more effective interventions and improved outcomes in managing hoarding behaviors in this population.

Unpacking affect maintenance and its association with depressive symptoms: integrating positive and negative affects.

ABSTRACTDepression is associated with increased maintenance of negative affect (NA) and reduced - blunted and short-lived - maintenance of positive affect (PA). Studies have focused on factors associated with the maintenance of NA, specifically, the emotion regulation strategy of brooding and the capacity to hold negative affective experiences in working memory (WM). Despite its theoretical importance, less attention has been given to factors associated with the maintenance of PA in depression. This study aims to synthesise factors playing a role in the maintenance of both NA and PA. Specifically, we used self-reported assessment of PA and NA regulation and performance-based measures of NA and PA processing in WM to predict depressive symptoms severity. Participants (N = 219) completed the Affective Maintenance Task (AMT, Mikels et al., 2008), which provided performance-based measures of PA and NA maintenance, and filled out questionnaires assessing brooding, positive rumination and depressive severity. Brooding, positive rumination and AMT-based measures of positive (but not negative) affective information processing were independently associated with depressive symptoms. We highlight the unique contributions of PA processing, as well as of self-reported emotion regulation strategies in understanding depression maintenance.

Multiple evolutionary transitions of reproductive strategies in a phylum of aquatic colonial invertebrates.

Parental care is considered crucial for the enhanced survival of offspring and evolutionary success of many metazoan groups. Most bryozoans incubate their young in brood chambers or intracoelomically. Based on the drastic morphological differences in incubation chambers across members of the order Cheilostomatida (class Gymnolaemata), multiple origins of incubation were predicted in this group. This hypothesis was tested by constructing a molecular phylogeny based on mitogenome data and nuclear rRNA genes 18S and 28S with the most complete sampling of taxa with various incubation devices to date. Ancestral character estimation suggested that distinct types of brood chambers evolved at least 10 times in Cheilostomatida. In Eucratea loricata and Aetea spp. brooding evolved unambiguously from a zygote-spawning ancestral state, as it probably did in Tendra zostericola, Neocheilostomata, and 'Carbasea' indivisa. In two further instances, brooders with different incubation chamber types, skeletal and non-skeletal, formed clades (Scruparia spp., Leiosalpinx australis) and (Catenicula corbulifera (Steginoporella spp. (Labioporella spp., Thalamoporella californica))), each also probably evolved from a zygote-spawning ancestral state. The modular nature of bryozoans probably contributed to the evolution of such a diverse array of embryonic incubation chambers, which included complex constructions made of polymorphic heterozooids, and maternal zooidal invaginations and outgrowths.

Effects of heat waves on telomere dynamics and parental brooding effort in nestlings of the zebra finch (Taeniopygia castanotis) transitioning from ectothermy to endothermy.

Heat waves are predicted to be detrimental for organismal physiology with costs for survival that could be reflected in markers of biological state such as telomeres. Changes in early life telomere dynamics driven by thermal stress are of particular interest during the early post-natal stages of altricial birds because nestlings quickly shift from being ectothermic to endothermic after hatching. Telomeres of ectothermic and endothermic organisms respond differently to environmental temperature, but few investigations within species that transition from ectothermy to endothermy are available. Also, ambient temperature influences parental brooding behaviour, which will alter the temperature experienced by offspring and thereby, potentially, their telomeres. We exposed zebra finch nestlings to experimental heat waves and compared their telomere dynamics to that of a control group at 5, 12 and 80 days of age that encapsulate the transition from the ectothermic to the endothermic thermoregulatory stage; we also recorded parental brooding, offspring sex, mass, growth rates, brood size and hatch order. Nestling mass showed an inverse relationship with telomere length, and nestlings exposed to heat waves showed lower telomere attrition during their first 12 days of life (ectothermic stage) compared to controls. Additionally, parents of heated broods reduced the time they spent brooding offspring (at 5 days old) compared to controls. Our results indicate that the effect of heat waves on telomere dynamics likely varies depending on age and thermoregulatory stage of the offspring in combination with parental brooding behaviour during growth.

Offspring thermal demands and parental brooding efficiency differ for precocial birds living in contrasting climates.

BACKGROUND: Chicks of precocial birds hatch well-developed and can search actively for food but their homeothermy develops gradually during growth. This makes them dependent on heat provided by parents ("brooding"), which is then traded off against other activities, mainly foraging. Although brooding has been documented in many precocial birds, little is known about the differences in the amount and efficiency of brooding care, brooding diel rhythmicity, and impact on the chick's growth, particularly between species living in different climatic conditions. RESULTS: We used multisensory dataloggers to evaluate brooding patterns in two congeneric species inhabiting contrasting climate zones: temperate Northern lapwing (Vanellus vanellus) and desert Red-wattled lapwing (Vanellus indicus). In accordance with our expectation, the adult desert lapwings brooded the chicks slightly less compared to the adult temperate lapwings. However, the desert lapwings brooded their chicks in higher ambient temperatures and less efficiently (i.e. they could not reach the same brooding temperature as the temperate lapwings), which are new and hitherto unknown brooding patterns in precocial birds. In both species, night brooding prevailed even during warm nights, suggesting a general brooding rule among birds. Although the high rates of brooding can reduce the time spent by foraging, we found no negative effect of the high brooding rate on the growth rate in either species. CONCLUSIONS: Our data suggest that the chicks of species breeding in colder climates may reduce their thermal demands, while their parents may increase the efficiency of parental brooding care. More research is however needed to confirm this as a rule across species.

Patterns of life stress and the development of ruminative brooding in adolescence: A person-centered approach.

Research links life stressors, including acute, chronic, and early life stress, to the development of ruminative brooding. However, singular forms of life stress rarely occur in isolation, as adolescents typically encounter stressors that vary on important dimensions (e.g., types, timings, quantities) across development. The current study employs latent profile analysis (LPA) to identify natural clusters of life stress that, over time, may be differently associated with ruminative brooding. Evaluations of episodic, chronic, and early life stress were conducted with community-recruited mid-adolescents (N = 241, Mage = 15.90 years, 53% female) and their parents using the UCLA Life Stress Interview and lifetime adversity portions of the Youth Life Stress Interview. Analyses identified four distinct patterns: low stress, high peer stress, moderate home / family stress, and multifaceted / high school stress. Adolescents in the high peer stress and moderate home / family stress profiles were at highest risk for developing a brooding style over time. Despite high overall levels of stress, teens in the multifaceted / high school stress profile were at not at elevated risk for developing a brooding style. Findings demonstrate the utility of person-centered approaches to identify patterns of stress exposure that heighten risk for brooding over time.

Aversive well-being comparisons in dysphoria and the role of brooding rumination.

OBJECTIVES: Individuals frequently engage in comparisons on how they are doing relative to different standards. According to the general comparative-processing model, comparisons can be perceived as aversive (appraised as threatening the motives of the comparer) or appetitive (appraised as consonant with, or positively challenging the motives). Research indicates that aversive comparisons are associated with depression. We hypothesize that aversive comparisons play a significant role in the relationship between brooding rumination and depression. Drawing on central propositions of control theory that discrepancies instigate rumination, we investigated the mediating role of brooding rumination in this relationship. Reflecting the different directionality, we also examined whether well-being comparisons mediate the relationship between brooding rumination and depression. METHODS: Dysphoric participants (N = 500) were administered measures of depression and brooding rumination, and the Comparison Standards Scale for Well-being. The latter assesses aversive social, temporal, counterfactual, and criteria-based comparisons regarding their (a) frequency, (b) perceived discrepancy to the standard, and (c) engendered affective valence. RESULTS: The relationship between the frequency of aversive comparisons with depression was partially accounted for by comparison discrepancy and engendered affective valence and brooding rumination. The relationship between rumination and depression was partially mediated by sequential comparison processes. CONCLUSIONS: Longitudinal research needs to unravel the underlying directionality of the relationship between depression, brooding, and comparison. Relevant clinical implications of well-being comparison are discussed.

Associations between daily affective experiences, trait and daily rumination on negative and positive affect: a diary study.

BACKGROUND: Rumination has mostly been studied in relation to depression, however, it may also occur in response to positive emotions (i.e., positive rumination) and therefore may be a protective factor related to the maintenance of positive mood. OBJECTIVE: We hypothesized that daily positive and negative affect would be associated with daily positive and negative rumination even after controlling for trait-level rumination. METHOD: We carried out a diary study with university students (n = 178), where participants had to answer short surveys online about their daily affect and daily rumination every evening for 10 days. We analyzed our data with multilevel regression in R. RESULTS: Daily positive and negative affect were significantly associated with daily negative and positive rumination, while trait-level rumination scores were not. Daily and trait-level rumination were moderately correlated (r = 0.333-0.440). CONCLUSIONS: Our findings highlight that daily rumination plays a more significant role in daily emotional experiences than trait rumination across positive and negative valence domains. Daily negative affect appears to be more closely related to higher daily negative rumination than the lack of daily positive rumination, which could be relevant for intervention strategies.

Is rumination associated with psychological distress after a cancer diagnosis? A systematic review.

Objective: The aim of this work was to review evidence on the association between psychological rumination and distress in those diagnosed with cancer. Methods: Six databases were searched for studies exploring rumination alongside overall assessments of psychological distress, depression, anxiety, or stress. Results: Sixteen studies were identified. Rumination was associated with distress cross-sectionally and longitudinally. However, once baseline depression was controlled for, the association was no longer seen. The emotional valence of ruminative thoughts and the style in which they were processed, rather than their topic, was associated with distress. Brooding and intrusive rumination were associated with increased distress, deliberate rumination had no association, and reflection/instrumentality had mixed findings. Conclusions: This review highlights that it is not necessarily the topic of content, but the style and valence of rumination that is important when considering its association with distress. The style of rumination should be the target of clinical intervention, including brooding and intrusion.

Phosphoproteome Reveals Extracellular Regulated Protein Kinase Phosphorylation Mediated by Mitogen-Activated Protein Kinase Kinase-Regulating Granulosa Cell Apoptosis in Broody Geese.

Geese have strong brooding abilities, which severely affect their egg-laying performance. Phosphorylation is widely involved in regulating reproductive activities, but its role in goose brooding behavior is unclear. In this study, we investigated differences in the phosphoprotein composition of ovarian tissue between laying and brooding geese. Brooding geese exhibited ovarian and follicular atrophy, as well as significant oxidative stress and granulosa cell apoptosis. We identified 578 highly phosphorylated proteins and 281 lowly phosphorylated proteins, and a KEGG pathway analysis showed that these differentially phosphorylated proteins were mainly involved in cell apoptosis, adhesion junctions, and other signaling pathways related to goose brooding behavior. The extracellular regulated protein kinase (ERK)-B-Cell Lymphoma 2(BCL2) signaling pathway was identified as playing an important role in regulating cell apoptosis. The phosphorylation levels of ERK proteins were significantly lower in brooding geese than in laying geese, and the expression of mitogen-activated protein kinase kinase (MEK) was downregulated. Overexpression of MEK led to a significant increase in ERK phosphorylation and BCL2 transcription in H2O2-induced granulosa cells (p < 0.05), partially rescuing cell death. Conversely, granulosa cells receiving MEK siRNA exhibited the opposite trend. In conclusion, geese experience significant oxidative stress and granulosa cell apoptosis during brooding, with downregulated MEK expression, decreased phosphorylation of ERK protein, and inhibited expression of BCL2.

Respiratory sinus arrhythmia moderates the interpersonal consequences of brooding rumination.

Brooding rumination is an intrapersonal emotion regulation strategy associated with negative interpersonal consequences. Resting respiratory sinus arrhythmia (RSA), a psychophysiological marker of self-regulatory capacity, may buffer the association between maladaptive emotion regulation and negative interpersonal behaviors. The current work examines the moderating effect of RSA on the association between brooding rumination and different negative interpersonal consequences. Across three convenience samples, individuals with lower RSA showed a stronger association between brooding rumination and more negative interpersonal behaviors as well as less perception of received instrumental social support (Study 1; n = 154), higher levels of interviewer-rated interpersonal stress (Study 2; n = 42) and a stronger indirect association between brooding rumination and depressive symptoms via daily interpersonal stress (Study 3; n = 222). These findings highlight the negative interpersonal consequences of brooding rumination, particularly among individuals with lower RSA.

Lethal and sublethal effects of thermal stress on octocorals early life-history stages.

The frequency and severity of marine heatwaves causing mass mortality events in tropical and temperate coral species increases every year, with serious consequences on the stability and resilience of coral populations. Although recovery and persistence of coral populations after stress events is closely related to adult fitness, as well as larval survival and settlement, much remains unknown about the effects of thermal stress on early life-history stages of temperate coral species. In the present study, the reproductive phenology and the effect of increased water temperature (+4°C and +6°C above ambient, 20°C) on larval survival and settlement was evaluated for two of the most representative Mediterranean octocoral species (Eunicella singularis and Corallium rubrum). Our study shows that reproductive behavior is more variable than previously reported and breeding period occurs over a longer period in both species. Thermal stress did not affect the survival of symbiotic E. singularis larvae but drastically reduced the survival of the non-symbiotic C. rubrum larvae. Results on larval biomass and caloric consumption suggest that higher mortality rates of C. rubrum exposed to increased temperature were not related to depletion of endogenous energy in larvae. The results also show that settlement rates of E. singularis did not change in response to elevated temperature after 20 days of exposure, but larvae may settle fast and close to their native population at 26°C (+6°C). Although previous experimental studies found that adult colonies of both octocoral species are mostly resistant to thermal stress, our results on early life-history stages suggest that the persistence and inter-connectivity of local populations may be severely compromised under continued trends in ocean warming.

Episodes of high recruitment buffer against climate-driven mass mortality events in a North Pacific seabird population.

Longitudinal studies of marked animals provide an opportunity to assess the relative contributions of survival and reproductive output to population dynamics and change. Cassin's auklets are a long-lived seabird that maximizes annual reproductive effort in resource-rich years through a behaviour called double brooding, the initiation of a second breeding attempt following the success of the first during the same season. Our objective was to explore whether double brooding influenced population change by contributing a greater number of future recruits. We fit temporal symmetry models to 32 years of mark-recapture data of Cassin's auklets to infer the mechanisms underlying the observed variability in per capita recruitment rates. We found that periodic peaks in recruitment were explained by an increase in available nest sites, the proportion of the population double brooding 4 years prior, and spring upwelling conditions. Estimates of population change suggests a relatively stable population throughout the time series, attributable to a 'floating' demographic class of sexually mature individuals excluded from breeding by competition which quickly fill vacant sites following periods of low adult survival. Our results highlight the importance of recruitment in maintaining the population of a long-lived seabird periodically impacted by adverse environmental conditions.

The relationship between rumination and NSSI: A systematic review and meta-analysis.

BACKGROUND: Rumination is a cognitive process that has been implicated in the onset and maintenance of a variety of psychological difficulties. The purpose of this review and meta-analysis was to examine the nature and strength of the relationship between rumination and non-suicidal self-injury (NSSI). METHODS: The protocol for this review was pre-registered (CRD42019148186). A literature search of electronic databases PsycINFO, CINAHL, MEDLINE, and Web of Science was performed from the earliest date available to March 2020. Thirty-nine eligible papers were identified. An additional seven papers were identified from a search conducted in September 2021, resulting in a total of 46 papers. Separate meta-analyses were undertaken for NSSI frequency and NSSI history, with studies grouped by rumination type (depressive, transdiagnostic, anger, brooding, reflection, catastrophising, overall). Moderator analyses were also conducted along with a narrative synthesis of adjusted associations and longitudinal studies. RESULTS: Rumination had a positive small association with NSSI frequency and a positive moderate association with NSSI history. The adjusted associations yielded mixed findings and most longitudinal research found rumination to be associated with prospective NSSI. LIMITATIONS: Most included studies had a moderate risk of bias and used a student sample. A limitation of this review was that only English language papers were included. CONCLUSIONS: Findings indicate that rumination is associated with NSSI, but more so the likelihood of engaging in NSSI overall than the frequency. Rumination-focused techniques for NSSI may therefore be of benefit. Further research is needed to understand this association, particularly with longitudinal studies that focus on state rumination rather than stable trait rumination. PRACTITIONER POINTS: Rumination was found to have a small to moderate association with NSSI. Some individuals who engage in NSSI may benefit from psychological techniques that target rumination. Most of the studies included had a moderate risk of bias.

Slow and Powerless Thought Dynamic Relates to Brooding in Unipolar and Bipolar Depression.

INTRODUCTION: Depression can be characterized by rumination that is featured by spontaneity and perseveration of internally oriented thoughts. At the same time, depressed subjects complain about abnormal slowness and lack of power/energy in their thoughts, suggesting abnormal "thought dynamics." The relationship between rumination and thought dynamics in depression remains unclear, though. METHOD: We investigated thought dynamics and rumination in healthy control, major depressive disorder (MDD), and depressed bipolar disorder (BD) subjects. The dynamics in the spontaneous shift between internally and externally oriented thoughts were measured by a novel method of continuous experience sampling whose time series was subjected to power and frequency analyses. Subjects filled out the Beck Depression Inventory-II and Ruminative Response Scale questionnaires to evaluate current depressive symptoms and ruminative responses to negative affect. The methods used to analyze data included χ2, Pearson correlation, ANOVA, and partial correlation. RESULTS: Our main findings are: (i) increased number and longer duration of internally oriented thought contents in MDD and BD; (ii) reduced thought dynamics with slower frequency (calculated in Hz) and decreased power (power spectral density) in shifting between internally and externally oriented thoughts, especially in MDD and, less strongly, in BD subjects; and (iii) power spectral density as a dimension of thought dynamics is related to brooding rumination with depression severity explaining high degrees of their variance. CONCLUSION: Our results show slow frequency and low power in the internal-external thought dynamic of acute MDD and depressed BD. Together with its close relation to depression severity and rumination, our findings highlight the key importance of abnormal dynamics on the cognitive level of depression.

Emotion regulation across the lifespan: age differences in intrapersonal and interpersonal strategies for the adjustment to the COVID-19 pandemic in four countries.

OBJECTIVES: Studies have shown age differences in adapting to the COVID-19 pandemic. The processes explaining these age differences remain unclear. Intrapersonal and interpersonal emotion regulation play an important role in psycho-social adjustment and develop across the lifespan. This study investigated whether differences in COVID-19-related adjustment disorder symptoms can be explained by age-differences in rumination in a multi-national sample. Furthermore, linguistic indicators of ruminative processing were examined with reference to age. METHODS: N = 1401 participants (from USA, UK, Switzerland, Germany, aged 18-88) completed an online survey and a writing task. Measures included brooding, co-brooding, adjustment disorder symptoms, and language indicators of negative self- and communal-focus . RESULTS: Older participants reported less adjustment disorder symptoms which was mediated by less (co-)brooding. Participants reporting more (co-)brooding wrote about COVID-19 more negatively. While in younger adults more self-focus was associated with higher ruminative brooding, in older adults it was associated with less brooding. CONCLUSION: These findings contribute to a better understanding of regulatory mechanisms that help explain age differences in mental health. They warrant further research considering age-related differences, as our results suggest not only more adaptive emotion regulation as resilience factor in older individuals but also different qualities of self-focus while processing stressful events.

Differential roles of reflection and brooding on the relationship between perceived stress and life satisfaction during the COVID-19 pandemic: A serial mediation study.

Perceived stress is associated with low life satisfaction; however, the underlying mechanism is relatively underexplored. This study investigated whether rumination might mediate this link during the highly stressful COVID-19 pandemic. Building on the distinction between the subtypes of rumination, we predicted that reflection and brooding would sequentially mediate this relationship and that maladaptive brooding would negatively influence life satisfaction. A representative sample of 316 adults was recruited from the greater Daegu area, where the first massive outbreak occurred in South Korea. After informed consent was obtained, they completed a package of questionnaires that included demographics, COVID-19-related experiences, perceived stress, life satisfaction, and rumination. A serial mediation analysis showed that reflection and brooding sequentially mediated the relationship between perceived stress and life satisfaction. As predicted, only brooding was negatively related to life satisfaction. In contrast, reflection per se was positively related to life satisfaction, and it negatively affected life satisfaction only through brooding. Our results extended the negative effect of brooding, as compared to reflection, in the pandemic. Given that reflection may easily turn into brooding under stress, it will be necessary to develop ways to guide people to counteract brooding while maintaining a reflective self-focus to preserve their well-being.

Attachment and brooding rumination during children's transition to adolescence: the moderating role of effortful control.

Brooding rumination is a maladaptive form of emotion regulation and confers a risk for psychopathology. Insecure attachment and low cognitive self-regulation are important antecedents of brooding. Yet, little is known about the developmental interplay between these two systems. Thus, we tested how children's attachment and cognitive self-regulation, conceptualized as effortful control (EC), interact to predict brooding. The participants in the three-wave longitudinal study were n = 157 children (10 to 14 years) and their mothers. Children reported their attachment and brooding, and mothers reported children's EC. Results showed that children with low avoidance received benefit from high EC to decrease brooding, whereas children with high anxiety brooded irrespective of EC. Thus, high EC may foster constructive emotion regulation among securely attached children, whereas the beneficial effects of high EC on emotional functioning seem to be overridden by insecurity. The functional role of cognitive self-regulation on different attachment strategies is discussed.
