Neuroticism affects nightmare distress through rumination.

BACKGROUND/AIMS: The role of neuroticism in predicting nightmare distress have been highlighted, and negative coping style may contribute to this relationship, but how these variables interact is limited. The present study aimed to explore how neuroticism and ruminative response contribute to producing nightmare distress, and to explore whether sex influences this relationship. METHODS: We recruited 758 university students, aged an average of 19.07. A moderated mediation model was built to examine the relationships among neuroticism, rumination, and nightmare distress (measured by dream anxiety scale), and explore whether sex could affect this relationship, using the SPSS PROCESS 3.5 macro. RESULTS: The moderated mediation analyses results showed that ruminative response-depression related can significantly partially mediate the relationship between neuroticism and dream anxiety (ß = 0.32), dream anxiety-sleep-related disturbances (ß = 0.11) and dream anxiety-daytime dysfunctions (ß = 0.21). However, the moderating effects of sex were not significant in all path from neuroticism to dream anxiety. CONCLUSION: The study provides a novel architecture on the underlying psychological mechanisms of neuroticism and nightmare distress. This interplay is assumed to be facilitated by ruminations, suggesting that interventions for individuals who suffer from nightmares may focus on their repetitive negative response strategies, especially in people with high neuroticism, irrespective of sex differences.

Psychometric properties of the Chinese version of the Courtauld Emotional Control Scale in women newly diagnosed with breast cancer.

PURPOSE: Emotional control, the attempt to suppress the expression of negative effects, is an essential factor in the prevalence of psychological distress in women with breast cancer. The Courtauld Emotional Control Scale (CECS) is a commonly used self-report tool for assessing emotional suppression in both clinical and general groups. This study aimed to validate the Chinese version of the Courtauld Emotional Control Scale (CECS) in women newly diagnosed with breast cancer. METHODS: The study involved 680 women newly diagnosed with breast cancer aged 25 to 76 (mean age = 48.19, standard deviation (SD) = 8.57) from Changsha (China). Data analysis included Cronbach's alpha coefficients, the intraclass correlation coefficient (ICC), Pearson's correlations, Independent-Samples T test, confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were conducted to determine the optimal model. For the best fitting model stability was assessed with tests for invariance across age, educational level, and employment status. RESULTS: Internal consistency (α = 0.987) and test-retest reliability (ICC = 0.715) of the CECS were presented. Results confirm the structure of the Chinese version of the CECS with 21 items divided into three dimensions, anger suppression (CECS_AG), depression suppression (CECS_MD), and anxiety suppression (CECS_AX). Convergent and known-groups validity were acceptable. Additionally, this model remained invariant across age, educational levels, and employment status. CONCLUSIONS: The Chinese version of the CECS has good psychometric properties in terms of reliability and validity, remaining invariant across age, educational levels, and employment status in women newly diagnosed with breast cancer.

Optimism and symptoms of anxiety and depression among Chinese women with breast cancer: the serial mediating effect of perceived social support and benefit finding.

OBJECTIVE: This research examines the direct and indirect relationships between optimism, perceived social support (PSS), benefit finding (BF), and anxiety and depressive symptoms among Chinese women with breast cancer (BC). METHODS: We recruited 512 patients, aged averagely 47.46(SD = 8.51) years from two hospitals located in Hunan province, China. The variables were assessed using the Optimism-Pessimism Scale (OPS), the Multidimensional Scale of Perceived Social Support (MSPSS), the Benefit Finding Scale (BFS), and the Hospital Anxiety and Depression Scale (HADS). Path analyses were conducted by Amos version 24.0 for Windows to test the hypothesized serial mediation model. RESULTS: Path analyses suggest a significant negative association between optimism and symptoms of anxiety and depression. The relationship was mediated by BF (ß = -0.085, SE = 0.015, 95% CI [-0.126, -0.055]), and by BF together with PSS (ß = -0.027, SE = 0.007, 95% CI [-0.047, -0.017]). The difference comparison between the two indirect effects was significant (ß = 0.057, SE = 0.015, 95% CI [0.034,0.101]). CONCLUSIONS: Our findings suggest that PSS, and BF are important mediators through which optimism may buffer symptoms of anxiety and depression among Chinese BC patients. Clinicians and healthcare practitioners should be aware of the importance of patients' emotional health and endeavor to offer emotional support, facilitate their capacity to improve their quality of life.

Disrupted functional connectivity of the cerebellum with default mode and frontoparietal networks in young adults with major depressive disorder.

Cerebellar dysconnectivity has repeatedly been documented in major depressive disorder (MDD). The cerebellum is composed of multiple functionally distinct subunits, and whether those subunits show similar or distinct dysconnectivity patterns with the cerebrum in MDD, is still unclear and needs to be further clarified. In this study, 91 MDD patients (23 male and 68 female) and 59 demographically matched healthy controls (22 male and 37 female) were enrolled to explore the cerebellar-cerebral dysconnectivity pattern in MDD by using the cutting-edge cerebellar partition atlas. Results showed that MDD patients exhibit decreased cerebellar connectivity with cerebral regions of default mode (DMN), frontoparietal networks (FPN), and visual areas. The dysconnectivity pattern was statistically similar across cerebellar subunits, with no significant diagnosis-by-subunit interactions. Correlation analyzes showed that cerebellar-dorsal lateral prefrontal cortex (DLPFC) connectivity is significantly correlated with anhedonia in MDD patients. Such dysconnectivity pattern was not affected by sex, which, however, should be further replicated in larger samples. These findings suggest a generalized disrupted cerebellar-cerebral connectivity pattern in MDD across all cerebellar subunits, which partially accounts for depressive symptoms in MDD, thus highlighting the pivotal role of the disrupted connectivity of cerebellum with DMN and FPN in the neuropathology of depression.

The Applicability of Acceptance and Commitment Therapy for Obsessive-Compulsive Disorder: A Systematic Review and Meta-Analysis.

BACKGROUND: Acceptance and commitment therapy (ACT), a third-generation cognitive behavioral therapy (CBT), has proved its efficacy amidst various mental disorders. A growing body of studies has shown that ACT can improve obsessive-compulsive disorder (OCD) severity in recent years. To assess the effect of ACT on OCD, we carried out a systematic review and meta-analysis to provide a basis for therapists to use different psychological dimensions of ACT for OCD. METHODS: PubMed, the Cochrane Library, EMBASE, EBSCO Host, and literature references were searched until May 2021. Randomized controlled trials (RCTs) and other study designs assessing the effect of ACT among adults suffering from OCD were examined. RESULTS: Fourteen studies, including 413 participants, published between 2010 and 2021 were identified. ACT made statistically significant progress in the Yale-Brown Obsessive-Compulsive Scale (YBOCS) compared with control conditions. CONCLUSION: After reviewing all the ACT studies, we acknowledge the plausibility of ACT in treating OCD and improving its symptoms for the clinical population. ACT can also be an adjunct therapy for other well-established treatments. It also favors targeting psychological inflexibility. Further well-controlled and high-quality RCTs are required for a better conclusion in further studies.

Decreased sensitivity to risk levels in ventral stratum in major depressive disorder during risky decision-making.

BACKGROUND: Reduced decision-making ability in depressive people has been observed both in daily life and experimental behavioral studies. However, the neurobiology of dysfunction in decision-making among depressive people is still unclear. METHODS: The study included 63 patients with major depressive disorder (MDD) and 49 healthy controls (HCs). The balloon analog risk task (BART), a risky decision-making paradigm, was used in a functional magnetic resonance imaging experiment to evaluate how brain activation was modulated by different levels of risk. RESULTS: No significant difference in behavioral performance was found. In prespecified brain regions, the activation of the left ventral stratum (VS) in MDD patients showed reduced modulation by risk levels compared with HCs. No significant group difference was found in prespecified dorsal anterior cingulate cortex (dACC) and right dorsal lateral prefrontal cortex (DLPFC). LIMITATIONS: BART did not isolate stages of making a choice and experiencing the outcome of the choice. CONCLUSION: The left VS was less sensitive to risk levels in MDD patients compared with HCs, indicating inefficient reward processing in risky decision-making in MDD.
