RESUMEN
The cumulative negative effects of prolonged Hypothalamic-Pituitary-Adrenal axis (HPA axis) activation are associated with several age-related diseases. Some psychological traits such as optimism and pessimism have been shown to be related to both health and the stress response, although their relationship with the HPA axis is inconclusive. More stable HPA axis biomarkers, such as hair samples of cortisol (HC) and dehydroepiandrosterone (HDHEA), would help to clarify the association between these psychological traits and HPA axis functioning. The main aim of this study was to test the relationships between optimism and pessimism and chronic stress biomarkers measured in hair (HC and HDHEA). Additionally, a secondary objective was to explore sex differences in HC and HDHEA levels and their relationship with these psychological traits. We measured optimism, pessimism, and their combination (dispositional optimism) using the Life Orientation Test Revised (LOT-R) and chronic stress biomarkers (HC and HDHEA) in 119 healthy participants (46 men and 73 women) between 56 and 81 years old who belonged to a university program. Regression analyses controlling for perceived stress and BMI indicated that higher dispositional optimism was related to lower HC and HC:HDHEAratio (ß = -0.256, p = .008 and ß = -0.300, p = .002, respectively). More specifically, higher pessimism was related to higher HC (ß = 0.235; p = .012) and HC:HDHEAratio (ß = 0.240; p = .011), whereas higher optimism was associated with a lower HC:HDHEAratio(ß = -0.205; p = .031). Moderation analyses showed no sex differences. To date, this is the first study to investigate the link between these traits and HC and HDHEA in older people. Our results confirm that positive and negative expectations about the future (i.e. optimism and pessimism) may play an important role in health due to their relationship with the HPA axis. They also strengthen the idea that the negative effects of pessimism have a greater weight than the protective effects of optimism in their relationship with HPA axis regulation.

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.

Self-compassion is a construct of positive psychology related to personality and cognitive factors. Perfectionism and interpersonal sensitivity are prevalent personality traits among university students and are associated with low self-compassion. Further research is required to comprehend how these mechanisms work in creating self-compassion. Consequently, the current study investigated the direct and indirect relationship between perfectionism and interpersonal sensitivity with self-compassion via repetitive negative thinking. To this end, a sample of 450 students studying in Tehran during the 2022 academic year was selected as the study sample. The results indicated that perfectionism and interpersonal sensitivity demonstrate a negative direct relationship with self-compassion, while perfectionism and interpersonal sensitivity exhibit an indirect relationship with self-compassion via repetitive negative thinking. Based on the findings, it can be concluded that the relationship between perfectionism and interpersonal sensitivity with self-compassion is not straightforward and that repetitive negative thinking can mediate this relationship. The results can be used to improve methods for increasing self-compassion and paying attention to personality, and cognitive factors can be an important step toward more effective self-compassion interventions.

BACKGROUND: Depression and anxiety are prevalent in youth populations and typically emerge during adolescence. Repetitive negative thinking (RNT) is a putative transdiagnostic mechanism with consistent associations with depression and anxiety. Targeting transdiagnostic processes like RNT for youth depression and anxiety may offer more targeted, personalised and effective treatment. METHODS: A meta-analysis was conducted to examine the effect of psychological treatments on RNT, depression and anxiety symptoms in young people with depression or anxiety, and a meta-regression to examine relationships between outcomes. RESULTS: Twenty-eight randomised controlled trials examining 17 different psychological interventions were included. Effect sizes were small to moderate across all outcomes (Hedge's g depression = -0.47, CI -0.77 to -0.17; anxiety = -0.42, CI -0.65 to -0.20; RNT = -0.45, CI -0.67 to -0.23). RNT-focused and non-RNT focused approaches had comparable effects; however, those focusing on modifying the process of RNT had significantly larger effects on RNT than those focusing on modifying negative thought content. Meta-regression revealed a significant relationship between RNT and depression outcomes only across all intervention types and with both depression and anxiety for RNT focused interventions only. CONCLUSION: Consistent with findings in adults, this review provides evidence that reducing RNT with psychological treatment is associated with improvements in depression and anxiety in youth. Targeting RNT specifically may not lead to better outcomes compared to general approaches; however, focusing on modifying the process of RNT may be more effective than targeting content. Further research is needed to determine causal pathways.

BACKGROUND: Repetitive negative thinking (RNT), a cognitive process that encompasses past (rumination) and future (worry) directed thoughts focusing on negative experiences and the self, is a transdiagnostic construct that is especially relevant for major depressive disorder (MDD). Severe RNT often occurs in individuals with severe levels of MDD, which makes it challenging to disambiguate the neural circuitry underlying RNT from depression severity. METHODS: We used a propensity score, i.e., a conditional probability of having high RNT given observed covariates to match high and low RNT individuals who are similar in the severity of depression, anxiety, and demographic characteristics. Of 148 MDD individuals, we matched high and low RNT groups (n = 50/group) and used a data-driven whole-brain voxel-to-voxel connectivity pattern analysis to investigate the resting-state functional connectivity differences between the groups. RESULTS: There was an association between RNT and connectivity in the bilateral superior temporal sulcus (STS), an important region for speech processing including inner speech. High relative to low RNT individuals showed greater connectivity between right STS and bilateral anterior insular cortex (AI), and between bilateral STS and left dorsolateral prefrontal cortex (DLPFC). Greater connectivity in those regions was specifically related to RNT but not to depression severity. CONCLUSIONS: RNT intensity is directly related to connectivity between STS and AI/DLPFC. This might be a mechanism underlying the role of RNT in perceptive, cognitive, speech, and emotional processing. Future investigations will need to determine whether modifying these connectivities could be a treatment target to reduce RNT.

The replay of task-relevant trajectories is known to contribute to memory consolidation and improved task performance. A wide variety of experimental data show that the content of replayed sequences is highly specific and can be modulated by reward as well as other prominent task variables. However, the rules governing the choice of sequences to be replayed still remain poorly understood. One recent theoretical suggestion is that the prioritization of replay experiences in decision-making problems is based on their effect on the choice of action. We show that this implies that subjects should replay sub-optimal actions that they dysfunctionally choose rather than optimal ones, when, by being forgetful, they experience large amounts of uncertainty in their internal models of the world. We use this to account for recent experimental data demonstrating exactly pessimal replay, fitting model parameters to the individual subjects' choices.

BACKGROUND: The Psychological Mediation Framework theorizes that repetitive negative thinking (RNT) mediates the relationship between minority stress and mental health, and this theory has been consistently supported by previous research. Yet, it is unclear whether the process or content of RNT is more important in the development of internalizing symptoms in sexual minorities. Consequently, the goal of the current study was to use structural equation modeling to determine whether there are significant indirect effects of repetitive negative thought content in the relationship between minority stress and internalizing psychopathology. METHODS: Measures of RNT, internalizing symptoms, and proximal minority stress were completed online by 205 cisgender sexual minority adults. Structural equation modeling was used to examine indirect effects of proximal stress on internalizing symptoms through content-independent RNT, depressive rumination, and sexual orientation-related rumination. RESULTS: Significant direct effects of proximal minority stress on internalizing symptoms were observed. Indirect effects of proximal stress on internalizing symptoms were observed for content-independent RNT and depressive rumination, but not sexual orientation-related rumination. CONCLUSIONS: The current study provides evidence that the process and affective valence of RNT contributes more to internalizing symptoms in sexual minorities when compared with sexual orientation-related content. Theoretical and clinical implications are discussed.

BACKGROUND: Despite the well-established role of repetitive negative thinking (RNT) in the prediction and maintenance of depression and anxiety, only minimal research to date has investigated RNT in the context of postnatal psychological adjustment. OBJECTIVE: We examined the relationships between RNT, associated maladaptive cognitive processes, infant responsiveness and psychopathology in a sample of first-time mothers (N = 235) with babies under 12 months. METHODS: Participants completed an online battery of measures that indexed RNT, dampening of positive affect, metacognitive beliefs about RNT, infant responsiveness, depression and anxiety symptoms. RESULTS: As predicted, RNT was correlated with depression. Controlling for depression, RNT was associated with anxiety, dampening positive affect and positive beliefs about RNT. RNT was inversely related to maternal responsiveness, but this relationship was accounted for by depression. CONCLUSIONS: Consistent with findings in the broader literature, RNT was associated with depression, anxiety and other unhelpful cognitive processes in the postnatal period, as well as with poor infant responsiveness. Whilst cross-sectional and preliminary, these data suggest there may be potential clinical utility in targeting RNT in first-time mothers.

Optimistic and pessimistic cognitive biases have been described in many animals and are related to the perceived valence of the environment. We, therefore, hypothesize that such cognitive bias can be adaptive depending on environmental conditions. In reward-rich environments, an optimistic bias would be favoured, whereas in harsh environments, a pessimistic one would thrive. Here, we empirically investigated the potential adaptive value of such bias using zebrafish as a model. We first phenotyped female zebrafish in an optimistic/pessimistic axis using a previously validated judgement bias assay. Optimistic and pessimistic females were then exposed to an unpredictable chronic stress protocol for 17 days, after which fish were euthanized and the sectional area of the different ovarian structures was quantified in both undisturbed and stressed groups. Our results show that zebrafish ovarian development responded to chronic stress, and that judgement bias impacted the relative area of the vitellogenic developmental stage, with pessimists showing higher vitellogenic areas as compared with optimists. These results suggest that pessimism maximizes reproductive investment, through increased vitellogenesis, indicating a relationship between cognitive bias and life-history organismal decisions.

Humor has been considered an effective emotion regulation strategy, and some behavioral studies have examined its superior effects on negative emotion regulation. However, its neural mechanisms remain unknown. Our functional magnetic resonance imaging study directly compared the emotion regulation effects and neural bases of humorous coping (reappraisal) and ordinary reappraisal following exposure to negative pictures. The behavioral results suggested that humorous reappraisal was more effective in downregulating negative emotions and upregulating positive emotions both in the short and long term. We also found 2 cooperative neural pathways involved in coping with negative stimuli by means of humor: the "hippocampal-thalamic-frontal pathway" and the "amygdala-cerebellar pathway." The former is associated with the restructuring of mental representations of negative situations and accompanied by an insightful ("Aha!") experience, while the latter is associated with humorous emotional release and accompanied by an expression of laughter ("Haha!"). Furthermore, the degree of hippocampal functional connectivity with both the thalamus and frontal cortex was positively correlated with changes in positive emotion, and this result implied that the degree of emotion regulation could be strongly directly related to the depth of cognitive reconstruction. These findings highlight that regulating negative emotions with humor involves cognitive restructuring and the release of positive emotions.

This paper sought to provide the first validation of a transdiagnostic measure of repetitive negative thinking - the Perseverative Thinking Questionnaire-Child version (PTQ-C) - in young people diagnosed with anxiety and depressive disorders. Participants (N = 114) were 11- to 17-year-olds with complex and comorbid presentations seeking treatment through Child and Adolescent Mental Health Services. Confirmatory factor analyses best supported a three-factor model for the PTQ-C; however, hypotheses of both perfect and close fit were rejected, and a subsequent bifactor model suggested minimal unique variance for each subscale. Results demonstrated good internal consistency, convergent validity and divergent validity for the total score and three PTQ-S subscales: core characteristics, perceived unproductiveness, and consumed mental capacity of negative repetitive thinking. PTQ-C scores did not account for additional variance in anxiety symptoms once worry was considered, indicating that retention of a content-specific measure may be warranted in clinical samples. Findings emphasize the importance of validating clinically relevant measures which were developed with subclinical populations in samples with diagnosed mental health disorders. PRACTITIONER POINTS: Validates Perseverative Thinking Questionnaire in anxious and depressed youth. Support for convergent and divergent validity, and internal consistency. Results suggest measure is appropriate for complex and comorbid presentations.

OBJECTIVES: Fatigue is a prominent symptom of Generalized Anxiety Disorder (GAD). However, the pathways contributing to elevated fatigue in GAD are poorly understood. Sleep disturbance, also prominent in GAD, only partially explains elevated fatigue in GAD. Repetitive negative thinking (RNT) is a cognitive feature of both GAD and sleep disturbance, and RNT has recently also been associated with elevated fatigue. Therefore, this study assessed whether elevated fatigue in GAD is accounted for by a combination of sleep quality and RNT. DESIGN: Between-group, correlational design in 64 primarily university-educated women with and without a GAD diagnosis. METHODS: Women completed self-report questionnaires assessing RNT experienced in the past few days, previous night's sleep quality, and current physical and mental fatigue. Hierarchical linear regressions were conducted to assess whether the relationship between GAD status and fatigue is accounted for by RNT and sleep quality. RESULTS: Women with GAD reported lower sleep quality, and higher RNT and physical and mental fatigue, compared to women without GAD. Sleep quality partly accounted for group differences in both types of fatigue (ß's > -0.4), whereas RNT fully accounted for group differences in both types of fatigue (ß's > 0.29). The relationship between RNT and both types of fatigue was fully accounted for by sleep quality (ß's > -0.39). CONCLUSIONS: These findings indicate that heightened RNT amongst women with GAD may be associated with elevated physical and mental fatigue via its detrimental effects on sleep quality. Interventions that reduce RNT may help to alleviate fatigue symptoms in women with GAD. PRACTITIONER POINTS: Women with Generalized Anxiety Disorder (GAD) have elevated fatigue and repetitive negative thinking (RNT), and poorer self-reported sleep quality, relative to women without GAD. Whereas sleep quality only partially accounts for elevated fatigue in GAD, RNT fully accounts for elevated fatigue, and the relationship between RNT and fatigue is fully accounted for by sleep quality. These findings provide novel evidence that women with GAD may have elevated fatigue because of the detrimental effects of RNT on sleep. These findings suggest that targeting RNT in treatment for GAD may help to reduce fatigue in GAD, by improving sleep quality.

Identifying factors related to healthcare professionals' mental health has become an imperative topic for offering mental health services to foster their psychological functioning. This study, for the first time, examined the mediating role of optimism and pessimism in the association between parental coronavirus anxiety and depression among Turkish healthcare professionals during the COVID-19 pandemic. Participants included 429 healthcare professionals whose age ranged between 22 and 61 years (50.3% female; M = 36.65, SD = 7.0). Results from mediation analysis revealed that parental coronavirus anxiety had a significant predictive effect on optimism, pessimism, and depression. Optimism and pessimism also had significant predictive effects on depression. Most importantly, optimism and pessimism mitigated the adverse impact of parental coronavirus anxiety on healthcare professionals' depression. The findings suggest that optimism is an essential source in reducing depression symptoms in the face of parental coronavirus experiences. Decision-makers and health organizations may integrate strength-based approaches into their guidelines to address parental coronavirus anxiety and depression.

While extensive evidence links service use for mental health problems to demographic variables and positive attitudes, studies have not explored the role of transdiagnostic risk factors, like distress intolerance (DI) and repetitive negative thinking (RNT). This study examined the relationship between parental DI and RNT on mental health treatment seeking for parents themselves and their children. Results suggest higher DI and RNT predict service use among parents (p < 0.05) but were not significantly associated with help seeking for their children, indicating that factors more proximal to the child may have greater influence when parents make treatment decisions for their children. Results also indicte that DI moderates the relationship between parent psychopathology and parent service use, such that parent psychopathology is significantly associated with service use for those with lower DI, but not at moderate or high levels of DI. Implications for marketing mental health information to parents and engaging them in treatment are discussed.

OBJECTIVES: Optimism and pessimism are distinct constructs that have demonstrated independent relationships with aspects of health and well-being. The purpose of this study was to investigate whether optimism or pessimism is more closely linked with physical and mental health among older adults. DESIGN: Cross-sectional survey. PARTICIPANTS: Community-dwelling older adults (N = 272) ages 59-95 in the southern United States. MEASUREMENTS: The Life Orientation Test-Revised and the Short Form 8. RESULTS: At the bivariate level, optimism was associated with higher physical health and mental health, while pessimism was associated with lower physical health and mental health. Multiple-regression analyses as well as comparison of correlation coefficients found that pessimism was more closely associated with physical health and mental health than optimism. CONCLUSIONS: These results add to the literature suggesting that, in terms of older adults' health and well-being, avoiding pessimism may be more important than being optimistic.

Objective/Background: Numerous psychiatric conditions characterized by repetitive negative thinking (RNT) are also frequently associated with disruptions in the duration and timing of sleep. The emerging literature supports that these types of sleep disruptions may be associated with negative psychological consequences such as depressed mood, anxiety, and poor emotion regulation, all of which have features of RNT. There is a paucity of research on the association between RNT and disruptions in sleep duration and timing in adolescents. The aim of the current study was to examine if sleep duration and timing in an adolescent sample would be predictive of RNT. Participants: Participants included 1,021 adolescents (ages 11 to 17) from a public school district in upstate New York. Methods: Participants completed a survey about their sleep practices, symptoms of psychopathology, and RNT. Results: Results indicated that sleep timing was predictive of RNT, but sleep duration was not. This result remained even after controlling for symptoms of psychopathology. Further, sleep onset latency was also predictive of RNT. Conclusions: These results indicate that it may be important to make the distinction between sleep duration and sleep timing. Sleep timing may uniquely impact RNT in adolescents.

OBJECTIVES: Women's greater prevalence of anxiety disorders compared to men is widely assumed to be partly due to gender differences in cognitive and behavioural factors that perpetuate anxiety, such as repetitive negative thinking (RNT) and avoidance. However, past studies assessing this assumption have not controlled for gender differences in baseline symptom severity, the type of stressful life experiences against which RNT and avoidance are measured, or emotional reactivity to these experiences. DESIGN: Using a two-group design, the present study controlled for these confounds by comparing avoidance and RNT in relation to a controlled symptom provocation task in spider phobic men and women with equivalent spider fear severity on the Fear of Spiders Questionnaire. METHODS: Participants engaged in a behavioural approach test (BAT) involving a live spider, during which they were assessed for avoidance (physical proximity to the spider) and subjective distress. Two weeks later, participants reported on their levels of negative affect and RNT experienced during the preceding weeks in relation to the BAT. RESULTS: Women exhibited greater avoidance and reported greater RNT than men, despite reporting comparable distress and negative affect. Gender remained a significant predictor of avoidance when accounting for distress and also remained a significant predictor of RNT when accounting for depressive symptoms and negative affect. CONCLUSIONS: These results provide in vivo evidence that heightened avoidance and RNT may perpetuate anxiety symptoms in women independently of gender differences in symptom severity, daily experiences, or emotional reactivity. PRACTITIONER POINTS: Following symptom provocation, men and women with spider phobia differ in cognitive and behavioural coping responses. Women exhibit greater avoidance and repetitive negative thinking than men, and these differences are not attributable to gender differences in symptom severity or emotional reactivity. These findings provide novel evidence for gender differences in maintaining factors that perpetuate anxiety disorders whilst accounting for confounding factors present in prior research.

INTRODUCTION: The Cognitive Debt hypothesis proposes that repetitive negative thinking (RNT), a modifiable process common to many psychological risk factors for Alzheimer's disease (AD) may itself increase risk. We sought to empirically examine relationships between RNT and markers of AD, compared with anxiety and depression symptoms. METHODS: Two hundred and ninety-two older adults with longitudinal cognitive assessments, including 113 with amyloid-positron emission tomography (PET) and tau-PET scans, from the PREVENT-AD cohort and 68 adults with amyloid-PET scans from the IMAP+ cohort were included. All participants completed RNT, anxiety, and depression questionnaires. RESULTS: RNT was associated with decline in global cognition (P = .02); immediate (P = .03) and delayed memory (P = .04); and global amyloid (PREVENT-AD: P = .01; IMAP+: P = .03) and entorhinal tau (P = .02) deposition. Relationships remained after adjusting for potential confounders. DISCUSSION: RNT was associated with decline in cognitive domains affected early in AD and with neuroimaging AD biomarkers. Future research could investigate whether modifying RNT reduces AD risk.

OBJECTIVE: We investigated the prevalence of anxiety and depression at diagnosis and at 1, 3, and 5 years after breast cancer diagnosis. We hypothesized that a low level of optimism (pessimism) at diagnosis could predict change in anxiety and depression 5 years later. METHODS: Three hundred sixty-seven women with operable breast cancer were included, and data were collected at all five-time points for 293 of these. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale (HADS). Dispositional optimism/pessimism was measured using the Life Orientation Test-Revised (LOT-R). Frequency analysis was used to determine the prevalence of anxiety and depression. Logistic regression was used to examine dispositional optimism/pessimism as a predictor of change in anxiety and depression 5 years after diagnosis. RESULTS: The prevalence rates of anxiety and depression 5 years after diagnosis were 26.3% and 9.6%, respectively. Predictors of change in anxiety 5 years after diagnosis were pessimism (odds ratio [OR] = 0.82; 95% confidence interval [CI]: 0.76-0.89, P < .001); younger age (OR = 0.96; 95% CI: 0.93-0.99, P = .005); and anxiety at diagnosis (OR = 2.41; 95% CI: 1.33-4.37, P = .004). Predictors of change in depression 5 years after diagnosis were pessimism (OR = 0.84; 95% CI: 0.77-0.94, P < .001) and comorbidity (OR = 1.51, 95% CI: 1.10-2.06, P = 0.01). CONCLUSION: Anxiety and depression did not decrease after the first postoperative year. Pessimism was a predictor of change in both anxiety and depression 5 years after breast cancer diagnosis.

BACKGROUND: Each year, over 1 million women in the USA undergo diagnostic breast biopsies, many of which culminate in a benign outcome. However, for many patients, the experience of awaiting biopsy results is far from benign, instead provoking high levels of distress. PURPOSE: To take a multifaceted approach to understanding the psychological experience of patients undergoing a breast biopsy. METHOD: Female patients (N = 214) were interviewed at an appointment for a breast biopsy, just prior to undergoing the biopsy procedure. Pertinent to the current investigation, the interview assessed various patient characteristics, subjective health and cancer history, support availability, outcome expectations, distress, and coping strategies. RESULTS: The findings revealed a complex set of interrelationships among patient characteristics, markers of distress, and use of coping strategies. Patients who were more distressed engaged in more avoidant coping strategies. Regarding the correlates of distress and coping, subjective health was more strongly associated with distress and coping than was cancer history; perceptions of support availability were also reliably associated with distress. CONCLUSION: Taken together, the results suggest that patients focus on their immediate experience (e.g., subjective health, feelings of risk, perceptions of support) in the face of the acute moment of uncertainty prompted by a biopsy procedure, relative to more distal considerations such as cancer history and demographic characteristics. These findings can guide clinicians' interactions with patients at the biopsy appointment and can serve as a foundation for interventions designed to reduce distress in this context.
