Abstract
Persistence is the propensity to maintain goal-directed actions despite adversities. While this temperamental trait is crucial to mitigate depression risk, its neurobiological foundations remain elusive. Developing behavioral tasks to capture persistence in animal models is crucial for understanding its molecular underpinnings. Here, we introduce the Sinking Platform Test (SPT), a novel high-throughput paradigm to measure persistence. Mice were trained to exit a water-filled tank by ascending onto a platform above water level. Throughout the training, mice were also occasionally exposed to "failure trials," during which an operator would submerge a platform right after the mouse climbed onto it, requiring the mouse to reach and ascend a newly introduced platform. Following training, mice were subjected to a 5-min test exclusively consisting of failure trials. Male and female mice exhibited comparable persistence, measured by the number of climbed platforms during the test. Furthermore, this index was increased by chronic administration of fluoxetine or imipramine; conversely, it was reduced by acute and chronic haloperidol. Notably, six weeks of social isolation reduced SPT performance, and this effect was rescued by imipramine treatment over the last two weeks. A 4-week regimen of voluntary wheel running also improved persistence in socially isolated mice. Finally, comparing transcriptomic profiles of the prefrontal cortex of mice with high and low SPT performance revealed significant enrichment of immediate-early genes known to shape susceptibility for chronic stress. These findings highlight the potential of SPT as a promising method to uncover the biological mechanisms of persistence and evaluate novel interventions to enhance this response.

Association between Grit and depressive symptoms at the timing of job start among medical residents during the COVID-19 pandemic in Japan: a cross-sectional study. MEDICAL EDUCATION ONLINE 2023; 28:2225886. [PMID: 37343594 PMCID: PMC10286665 DOI: 10.1080/10872981.2023.2225886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/11/2023] [Accepted: 06/12/2023] [Indexed: 06/23/2023]
Abstract
INTRODUCTION The COVID-19 pandemic had an additional negative impact on the mental health of healthcare workers, including residents. Previous studies revealed that grit, which is an individual trait to achieve long-term goals unrelated to intelligence quotient, is not only positively associated with academic achievement and career success but also negatively correlated with depression. This study aimed to examine the association between grit and depressive symptoms among residents at the time of job start during the coronavirus disease 2019 (COVID-19) pandemic in Japan. MATERIALS AND METHODS This cross-sectional study used data from all post-graduate year 1 residents from March 2020 to April 2022 at Tokyo Medical and Dental University, Tokyo, Japan. Grit was measured by the Japanese version of Grit-S. The resident's depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. The association of interest was examined using logistic regression analysis. RESULTS Among 221 residents, 28 (12.7%) have depressive symptoms. One unit increase in Grit-S score after adjusting for age, sex, graduated university, and sleeping hours was associated with lower odds of having depressive symptoms by 63% (odds ratio [OR]: 0.37; 95% confidence interval [CI]: 0.19-0.74). Further, the perseverance of effort subscale score was associated with lower odds of having depressive symptoms after covariate adjustment (OR: 0.43; 95% CI: 0.22-0.84). CONCLUSIONS Higher grit scores were associated with lower odds of having depressive symptoms among residents at the timing of job start during the COVID-19 pandemic. Regular mental health assessment is particularly important for residents with low grit scores at entry.

Abstract
There is evidence showing that the triarchic model of grit and its dimensions (i.e., perseverance of effort, consistency of interests, and adaptability to situations) predict engagement and well-being outcomes in high school and undergraduate students during the COVID-19 pandemic outbreak. However, there has been limited research on how this model of grit relates to engagement and optimal psychological outcomes in primary school students. This research investigates the association of grit's dimensions with academic engagement in math and science as well as well-being outcomes (i.e., positive emotions, negative emotions, and flourishing) in primary school students. Participants were primary school students (Mage = 10.42; SDage = 1.26) from Hong Kong (n = 279) and Macau (n = 124). Results showed that perseverance of effort positively predicted cognitive and behavioral engagement in math as well as positive emotions even after controlling for demographic covariates (i.e., age, gender, setting, and year level), conscientiousness, and achievement goal orientations. Adaptability to situations positively predicted cognitive and social engagement in math and flourishing. Consistency of interests negatively predicted both cognitive engagement in science and negative emotions. Indeed, this study indicates that perseverance and adaptability may facilitate children's positive academic and psychological functioning during the COVID-19 pandemic outbreak.

Abstract
Impulsivity is a multidimensional construct. The UPPS-P model of impulsivity differentiates five distinct dimensions: negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking. The present study, reports the first translation and validation of the recently revised short form of the UPPS-P scale (S-UPPS-P) on a Persian-speaking sample, examining the relationship between impulsivity and working memory. who also completed the Positive and Negative Affect Scale (PANAS), the Buss and Perry Aggression Questionnaire, the Behavioral Inhibition and Activation Scales (BIS/BAS), and the Wechsler Digit Span Task (WDST). A series of confirmatory factor analyses, and Cronbach's alpha results supported the factor structure of the scale. The findings supported the S-UPPS-P model's hypothesized correlations with PANAS, aggressiveness, and the construct validity of the model. The results of hierarchical regression analysis showed that backward and forward digit span scores of the WDST predicted the S-UPPS-P impulsivity scores over the portion explained by BIS/BAS, PANAS, and aggression scores. To conclude, the revised S-UPPS-P Impulsive Behavior Scale was well supported even in a very different population than usually sampled, adding to growing evidence that it assesses distinct but interrelated aspects of the impulsivity construct. Our findings also suggest that attentional capacities and working memory play important roles in the prediction of impulsivity.

Abstract
OBJECTIVES Blunted cardiovascular reactivity is associated with a distinct behavioural profile of greater exposure to early life adversity, coupled with higher levels of behavioural disengagement and symptoms of depression. The present study sought to extend on this work by investigating if behavioural clusters with distinct patterns of reactivity were related to health and behavioural outcomes at baseline and at a 4-year follow-up. METHODS Hierarchical cluster analyses were conducted using longitudinal data drawn from the Midlife Development in the United States (MIDUS 2) Biomarker Project and the MIDUS 3 follow-up 4 years later. During MIDUS, 2 participants (N = 513) underwent a standardized stress testing protocol and had their blood pressure and heart rate monitored throughout. In addition, hierarchical cluster analyses were conducted on responses from measures of early life adversity, behavioural disengagement and depression. Binary logistic regressions were conducted to determine whether cluster membership was related to health and behavioural outcomes which were taken at both time points. RESULTS Three behavioural clusters emerged with statistically different blood pressure reactivity patterns. The cluster characterized by greater exposure to early life adversity, higher levels of behavioural disengagement and depressive symptoms, had relatively lower blood pressure reactivity patterns compared with both the exaggerated reactivity cluster and the cluster similar to the sample mean. In fully adjusted models, this cluster was associated with hypertension (p = .050) and depressed affect (p = .033), while Cluster 1 characteristic of an exaggerated blood pressure reactivity profile was associated with depressed affect (p < .001). Cluster membership did not significantly predict future health status. CONCLUSION This study extends research on behavioural clusters characteristic of reactivity profiles to demonstrate how they relate to health and behavioural outcomes during MIDUS 2.

Abstract
The present study explored whether authentic pride (AP) and hubristic pride (HP) were differently associated with cognitive reappraisal strategy. In study 1, undergraduates (n = 235) completed a battery of self-report questionnaires, including the Authentic and Hubristic Pride-Proneness Scale (AHPPS), Emotion Regulation Questionnaire (ERQ), and emotion regulation questionnaire (ERP-R). The results showed that AP significantly predicted successful down-regulation of negative emotions via a spontaneous cognitive reappraisal strategy. However, hubristic pride (HP) was negatively associated with spontaneous cognitive reappraisal. In study 2, participants with trait AP (n = 31) and trait HP (n = 29) undergoing continuous electroencephalogram (EEG) recording were required to reinterpret emotional pictures to down-regulate/up-regulate their negative/positive emotional reactions. The results showed that individuals with AP reported lower levels of emotional arousal and lower amplitudes of late positive potentials (LPPs) than did individuals with HP in response to negative pictures during the down-regulation of negative emotions, but not during passive viewing or up-regulation of positive emotions. Across two studies, these findings showed that individuals with AP could utilize the cognitive reappraisal strategy (spontaneously in daily life and under experimental instructions) to down-regulate negative emotions more successfully relative to individuals with HP.

Abstract
Job-search is considered as a developmental task for college students to move from campus to workplace. Based on the self-determination theory, 859 Chinese college students were selected as the study sample and hierarchical regression analysis was used to explore the perseverance of effort and consistency of interest on job-search intensity and clarity. The survey showed that the perseverance of effort has a significant positive effect on the job-search intensity, while it has no significant positive effect on job-search clarity. Consistency of interest has a significant negative effect on job-search intensity and a significant positive effect on job-search clarity. Theoretical and practical implications are discussed and the directions for future research are outlined in this study.

Abstract
BACKGROUND There is considerable evidence documenting associations between early life adversity, behavioral disengagement, and depression with blunted cardiovascular reactivity to acute psychological stress. However, while often examined as independent predictors, it is also likely that a combination of these factors uniquely relate to cardiovascular reactivity. PURPOSE The present study employed multivariate cluster analysis to examine if distinct combinations of these outcomes relate to cardiovascular stress reactivity. METHODS Participants (N = 467) were predominantly female (60.6%) with a mean age of 19.30 years (SD = 0.82). Measures of early life adversity, behavioral disengagement, and depression were completed; in addition, participants had their blood pressure and heart rate monitored throughout a standardized stress testing session. Cardiovascular reactivity was calculated as the difference between mean stress and mean baseline cardiovascular values. RESULTS Analyses revealed two clusters with distinct patterns of exposure to early life adversity, levels of behavioral disengagement and depression, uniquely related to cardiovascular reactivity. In unadjusted models, Cluster 1 that was characterized by greater exposure to early life adversity, higher levels of behavioral disengagement and depression, was associated with lower systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) reactivity. Cluster 2 was characterized by reactivity values similar to the sample means. In fully adjusted models, Cluster 1 predicted heart rate reactivity to stress. CONCLUSIONS The present study identifies a behavioral cluster that is characteristic of a blunted heart rate reactivity profile, significantly extending the research in this area.

Abstract
Grit is associated with positive outcomes in nonclinical samples. However, no studies have examined grit in relation to psychopathology in patients with clinical mood or anxiety disorders. Research and clinical experience suggest that individuals who hoard struggle with characteristics associated with grit, such as task persistence, impulsivity, and self-control. The authors tested the hypothesis that hoarding symptoms are associated with less grit in a sample of individuals (N = 72) presenting for treatment to an anxiety disorders clinic. After covarying symptoms of the four mood and anxiety disorders most commonly comorbid with hoarding disorder (viz. depression, generalized anxiety, social anxiety, and obsessive-compulsive disorder), the authors found that hoarding symptoms were associated with less grit, and the effects were medium-to-large. These results indicate that grit is worthy of investigation in individuals with hoarding disorder using methodologies that permit inferences about causality, and with attention to clinical implications for prevention or treatment.
