Higher self‐reported rumination, a common form of trait perseverative cognition, is linked with lower resting heart rate variability (HRV), which indicates poorer cardiac function and greater disease risk. A meta‐analysis and systematic review indicated that in samples with fewer European Americans, the association of rumination with both heart rate and blood pressure was stronger. Thus, trait rumination may be more strongly associated with resting HRV among ethnically minoritized populations. The current study investigated whether differences in the association of self‐reported rumination with resting HRV varied by ethnicity in a sample (N = 513; Mage = 19.41; 226 Women) of self‐identified African Americans (n = 110), Asian Americans (n = 84), and European Americans (n = 319). Participants completed a five‐minute baseline period to assess resting HRV, followed by the Ruminative Responses Scale, which contains three facets of rumination including brooding, depressive, and reflective rumination. On average, Asian Americans reported higher levels of rumination relative to European Americans. African Americans had higher resting HRV than Asian Americans. Adjusting for covariates, higher self‐reported rumination was significantly associated with lower resting HRV in both African and Asian Americans, but not significantly so in European Americans. This finding was consistent for brooding and reflective, but not depressive rumination. Overall, this study lends insight into a psychological mechanism—rumination—that may impact health disparities among ethnically minoritized individuals, contributing to an understanding of how stress gets under the skin among such minoritized populations.

Abstract: Self‐esteem moderates the relationship between stress and (cardiovascular) health, with low self‐esteem potentially exacerbating the impact of stressors. Boosting self‐esteem may therefore help to buffer against stress. Subliminal evaluative conditioning (SEC), which subliminally couples self‐words with positive words, has previously been successfully used to boost self‐esteem, but the existing studies are in need of replication. In this article, we aimed to replicate and extend previous SEC studies. The first 2 experiments simultaneously examined whether SEC increased self‐esteem (Experiment 1, n = 84) and reduced cardiovascular reactivity to a stressor in high worriers (Experiment 2, n = 77). On the basis of these results, the 3rd experiment was set up to examine whether an adjusted personalized SEC task increased self‐esteem and reduced cardiac activity in high worriers (n = 81). Across the 3 experiments, no effects were found of SEC on implicit or explicit self‐esteem or affect or on cardiovascular (re)activity compared to a control condition in which the self was coupled with neutral words. The results do not support the use of the subliminal intervention in its current format. As stress is highly prevalent, future studies should focus on developing other cost‐effective and evidence‐based interventions. [ABSTRACT FROM AUTHOR]

Stress-related cognitive processes may occur outside of awareness, here referred to as unconscious stress, and affect one's physiological state. Evidence supporting this idea would provide necessary clarification of the relationship between psychological stress and cardiovascular (CV) health problems. We tested the hypothesis that increases in mean arterial pressure (MAP) and total peripheral resistance (TPR) and decreases in heart rate variability (HRV) would be larger when threatening stimuli are presented outside of awareness, or subliminally, compared with neutral stimuli. Additionally, it was expected that trait worry and resting HRV, as common risk factors for CV disease, would moderate the effect. We presented a subliminal semantic priming paradigm to college students that were randomly assigned to the threat ( n = 56) or neutral condition ( n = 60) and assessed changes from baseline of MAP, TPR, and HRV. Level of trait worry was assessed with the Penn State Worry Questionnaire. The findings indicate that CV activity changed according to the hypothesized pattern: A higher MAP and TPR and a lower HRV in the threat condition compared with the neutral condition were found with practically meaningful effect sizes. However, these findings were only statistically significant for TPR. Furthermore, changes in CV activity were not moderated by trait worry or resting HRV. This is the first study to explicitly address the role of subliminally presented threat words on health-relevant outcome measures and suggests that unconscious stress can influence peripheral vascular resistance.

Objectives: Several studies have shown that perseverative, worrisome thoughts are prospectively related to subjective health complaints (SHC) and that a short worry postponement intervention can decrease these complaints. As SHC and worry are prevalent and costly, we tested whether the intervention can be offered online to reduce these complaints in the general population.Design: A randomized parallel-group trial was conducted with self-selected participants from the general population.Methods: Via the research website, 996 participants were instructed to register their worrying for 6 consecutive days. The intervention group was instructed to postpone worry to a special 30-min period in the early evening. The Subjective Health Complaints inventory, as administered before and after the intervention, and daily worry frequency and duration were considered the primary outcomes.Results: Three hundred and sixty-one participants completed the study. Contrary to our expectation, the registration group (n = 188) did not differ from the intervention group (n = 163) in SHC (ηp² = .000, CI [0.000-0.003]), or in worry frequency or duration. Nevertheless, the different worry parameters were moderately related to SHC (r between .238 and .340, p ≤ .001).Conclusions: In contrast to previous studies using pen-and-pencil versions of the worry postponement intervention, this study suggests that a direct online implementation was not effective in reducing SHC and worry. Overall, participants had high trait worry levels and reported difficulty with postponing worrying. Reducing SHC and worries via the Internet might require more elaborate interventions that better incorporate the advantages of delivering interventions online.Statement Of Contribution: What is already known on this subject? The perseverative cognition hypothesis argues that perseverative cognition, such as worry and rumination, acts as a mediator by which psychosocial stress may produce negative health effects. Prior research has indeed shown that worry and subjective health complaints (SHC) are prospectively related, but causality studies - that is, showing that changes in worry induce changes in health outcomes - are scarce and have mainly been conducted in young samples. These studies showed that reducing worry, using a worry postponement intervention, can reduce daily worrying and SHC. What does this study add? Trait and daily worrying are associated with SHC. An online worry postponement intervention is ineffective in reducing worry and SHC. Paper-and-pencil interventions cannot directly be used as online interventions. [ABSTRACT FROM AUTHOR]

Reduced heart rate variability (HRV) is proposed to mediate the relation between depressive symptoms and cardiovascular health problems. Yet, several studies have found that in women depression is associated with higher HRV levels, whereas in men depression is associated with lower HRV levels. So far, these studies have only examined gender differences in HRV levels using a single assessment. This study aimed to test the interactive effects of gender and sadness on ambulatory-assessed HRV levels. A sample of 60 (41 women) employees participated in an ambulatory study. HRV levels (mean of successive differences; MSD) were continuously measured for 24 h. During the daytime, hourly assessments of sadness and other mood states were taken, while depressive symptoms were assessed with the Center for Epidemiologic Studies Depression scale (CES-D). Gender differences were observed when examining the impact of average daily sadness on MSD. In women, but not in men, the total amount of sadness experienced during the day was associated with higher circadian MSD levels. These findings suggest that researchers need to take gender differences into account when examining the relation between sadness, HRV, and cardiovascular problems. [ABSTRACT FROM AUTHOR]

Objectives In this study, we tested whether high levels of daily worrying are associated with linking, a tendency to overvalue the attainment of specific lower level goals for attaining higher level goals, and more specifically the attainment of experiencing happiness. Methods Thirty-two patients suffering from work stress complaints and awaiting a stress management treatment and 31 healthy adults, who formed the comparison group, filled in a goal linking questionnaire and two widely used trait worry questionnaires. Subsequently, they reported the frequency and duration of worry during 14 consecutive days and nights. Results The patients suffering from work stress complaints scored higher on the linking questionnaire and worried almost twice as much as the healthy comparison group, especially during the night-time. Furthermore, goal linking was a stronger predictor of the frequency and duration of worry in daily life than the trait worry questionnaires and this was independent of the observed group differences in daily worry. Conclusions These findings provide evidence that people who believe that their happiness is strongly dependent on the attainment of specific lower level goals worry frequently in daily life. Linking seems to be at least partly responsible for the excessive worry found in high work stress. Practitioner points Worry is elevated in patients seeking professional help for work stress complaints, compared to healthy controls, The higher levels of worry in the patient group were related to elevated tendencies to overvalue the attainment of specific lower level goals as a means to attain higher level goals ('linking')., It could be beneficial for high worriers to learn how to reduce linking tendencies., No strong inferences on the direction of the association between worry and linking can be made, as we relied on correlational data in which a linking questionnaire predicted worry in daily life.

Sensitization is conceptually related to cognitive bias in experimental psychopathology, and they share the basic mechanism of neuronal sensitization. Every strongly relevant individual concern, like fears, can yield cognitive bias or "cognitive-emotional sensitization". It might also be present for bodily and environmental information related to illness, and could be an etiological factor in medically unexplained complaints. Physiological and cognitive sensitization are theoretically compared. There is evidence for cognitive-emotional sensitization in some medically unexplained somatic complaints, and negative affect is suggested as a catalyst. Prolonged cognitive-emotional sensitization ("perseverative negative cognition" or worry, rumination) might even have demonstrable somatic pathological effects. It is concluded that sensitization may be organized at different levels, both in the organism and in the larger living system within which the organism is subsumed. This view might not only help to clarify medically unexplained pain syndromes, but virtually every subjective complaint, both with and without recognized physiopathology. [ABSTRACT FROM AUTHOR]
