BACKGROUND Depression is a leading global health concern with high suicide rates and recurrence.Cognitive models suggest that mental pain and automatic thoughts are central to depression's impact.The hypothesis is that self-compassion will be negatively associated with mental pain,mediated by automatic thoughts.AIM To determine the mediating role of automatic thoughts in the relationship between self-compassion and mental pain in individuals with depression.METHODS This cross-sectional study included 389 inpatients with depression from Tianjin Anding Hospital.Participants completed the Self-Compassion Scale-Chinese Version(SCS-C),Automatic Thought Questionnaire(ATQ),and Orbach&Mikulincer Mental Pain Scale-Chinese Version(OMMP).Data were analyzed using Pearson correlations,multiple linear regressions,and mediation analysis.RESULTS The SCS-C total score was 68.95±14.89,ATQ was 87.02±28.91,and OMMP was 129.01±36.74.Correlation analysis showed mental pain was positively associated with automatic thoughts(r=0.802,P<0.001)and negatively with selfcompassion(r=-0.636,P<0.001).Regression analysis indicated automatic thoughts(β=0.623,P<0.001)and self-compassion(β=-0.301,P<0.001)significantly predicted mental pain.Mediation analysis confirmed automatic thoughts partially mediated the relationship between self-compassion and mental pain(ab=-0.269,95%CI:-0.363 to-0.212).CONCLUSION Self-compassion is inversely related to mental pain in depression,with automatic thoughts playing a mediating role.These findings suggest potential therapeutic targets for alleviating mental pain in depressed patients. 展开更多

Objectives: The purpose of this study is to test the psychometric properties and validity of the unconditional positive self-regard scale (UPSR) and its two subscales developed by Patterson & Joseph (2006). It also aims to examine and compare the concepts of UPSR with self-compassion and its relation to mental well-being. Design: Correlation survey design validations of the UPSR scale (Patterson & Joseph, 2006). Methods: The validation was conducted using an undergraduate and postgraduate student opportunity sample, n = 179. Internal consistency was assessed using Cronbach’s coefficient alpha and inter-item correlations. Convergent and divergent validity was explored in terms of correlations with self-compassion, depression (PHQ-9) and anxiety (GAD-7) scales. Results: There was good internal consistency for both the UPSR scale and the self-regard subscale and somewhat questionable internal consistency for the conditionality subscale. Overall the scale appears to be relatively consistent, supporting the previous findings reported by Patterson & Joseph (2006). The results supported the hypothesis that UPSR is positively correlated with a measure of self-compassion and negatively correlated with measures of depression (PHQ-9) and anxiety (GAD-7). Conclusions: The UPSR scale is a valid measure of the person-centred concept of unconditional positive self-regard. This supports the potential use of the UPSR scale for evaluating therapeutic change for client-centred practitioners through the use of this non-medicalized tool. 展开更多

Arbitration is a key non-litigation commercial mechanism for the resolution of disputes, and the quality and credibility of its awards depend largely on the competency of the arbitrators. However, the selection and evaluation systems for arbitrators in China have long faced challenges such as the vague criteria for competency and an unclear professionalization path for arbitrators. To address these issues, this study is grounded in the context of actual Chinese arbitration practice and based on the competency iceberg model. Through a methodological approach encompassing literature reviews, behavioral event interviews, expert revisions, and questionnaire surveys, a Chinese Arbitrator Competency Scale was developed and validated in this study. Examination of the findings indicated that the scale needed to consist of five dimensions—communication and coordination, cognitive skills, ethical conduct, work motivation, and personality traits—and possess a total of 28 specific indicators. Confirmatory analysis of the factors demonstrates a good fit for the five-dimensional model, with each of the dimensions exhibiting high reliability and validity. This scale is innovative in integrating the competency elements with Chinese characteristics, such as commercial acumen, crosscultural mediation skills, and adaptability to the local rule of law. This research not only enriches the competency theory in regard to the field of human resource management but also provides a scientific framework of standards and measurement tools for the selection, training, and evaluation of arbitrators. It thus has significant practical value for enhancing the professionalism and international competitiveness of China's arbitration system. 展开更多

Owing to intensified globalization and informatization,the structures of the urban scale hierarchy and urban networks between cities have become increasingly intertwined,resulting in different spatial effects.Therefore,this paper analyzes the spatial interaction between urban scale hierarchy and urban networks in China from 2019 to 2023,drawing on Baidu migration data and employing a spatial simultaneous equation model.The results reveal a significant positive spatial correlation between cities with higher hierarchy and those with greater network centrality.Within a static framework,we identify a positive interaction between urban scale hierarchy and urban network centrality,while their spatial cross-effects manifest as negative neighborhood interactions based on geographical distance and positive cross-scale interactions shaped by network connections.Within a dynamic framework,changes in urban scale hierarchy and urban networks are mutually reinforcing,thereby widening disparities within the urban hierarchy.Furthermore,an increase in a city’s network centrality had a dampening effect on the population growth of neighboring cities and network-connected cities.This study enhances understanding of the spatial organisation of urban systems and offers insights for coordinated regional development. 展开更多

BACKGROUND Studies have indicated that childhood exposure to domestic violence is a common factor in posttraumatic growth(PTG)and posttraumatic stress disorder(PTSD),but it is unclear whether PTG and PTSD share a common/different underlying mechanism.AIM To explore the common/different underlying mechanism of PTG and PTSD.METHODS Between February 12 and 17,2020,a nationwide cross-sectional online survey was conducted in China among 2038 university students,and a self-administered questionnaire was used for the data collection.The data included demographic characteristics,such as age,gender,and subjective social economic status,and childhood exposure to domestic violence scale that was selected from the Chinese version of revised Adverse Childhood Experiences Question,Self-compassion Scale,Connor–Davidson Resilience Scale,Posttraumatic Growth Inventory,and the Abbreviated PTSD Checklist-Civilian version.A structural equation model was used to test the hypotheses.RESULTS Exposure to domestic violence was significantly associated with PTG and PTSD via a 1-step indirect path of self-compassion(PTG:β=-0.023,95%CI:-0.44 to-0.007;PTSD:β=0.008,95%CI:0.002,0.014)and via a 2-step indirect path from self-compassion to resilience(PTG:β=-0.008,95%CI:-0.018 to-0.002;PTSD:β=0.013,95%CI:0.004-0.024).However,resilience did not mediate the relationship between exposure to domestic violence and PTG and PTSD.CONCLUSION PTG and PTSD are common results of childhood exposure to domestic violence,which may be influenced by self-compassion and resilience. 展开更多

Objective: To determine how self-compassion and empathy might influence the degree of burnout, secondary traumatic stress and compassion satisfaction among medical students and residents. Methods: Cross-sectional survey of medical students and select residency programs at Henry Ford Hospital in Detroit, Michigan. Respondents completed the Professional Quality of Life Scale (burnout, secondary traumatic stress and compassion satisfaction), Neff’s Self-Compassion Scale, and the empathic concern and personal distress subscales of the Interpersonal Reactivity Index. Results: The response rate was 28.6%. 23.9% and 27.3% of medical trainees reported high levels of burnout and secondary traumatic stress, respectively. Females reported greater empathy but lower self-compassion than males. Greater concern for others and oneself and lower personal distress predicted greater pleasure derived from professional work. Less concern for others and lower concern for oneself predicted greater burnout. Conclusions: Compassion for oneself and for others within their care appears to ameliorate burnout and can increase professional satisfaction. Initiatives to foster empathy and self-compassion may enhance individual well-being. 展开更多

The present study has been conducted in order to determine the self-compassion levels of the students studying in various departments of the faculties of sports sciences and performing sports, and thus to find out whether certain variables such as their branch, department and families have an effect on their self-compassion levels. The "Self-compassion Scale" was used as the data collection tool in the study. In the present study, when the self-compassion levels of the students of the faculties of sports sciences were evaluated by various variables, it was found that the self-compassion levels of the students of Mugla University were significantly higher than those of the students of Ankara University, that the self-compassion levels of the students studying in the department of teaching were higher than those of the students studying in the department of coaching, and that the self-compassion levels of the students performing the branch of football were significantly higher than those of the students performing the branch of volleyball. When the students were compared based on the cities they live, it was found that the students living in the province of Mugla had significantly higher levels of self-compassion comparing to the students living in the province Ankara. Consequently, it was determined that the self-compassion levels of the students studying in various departments of the faculties of sports sciences were moderate, and that the differences in the province, department and the sports branch had an effect on the levels of self-compassion. 展开更多

Contingent self-esteem captures the fragile nature of self-esteem and is often regarded as suboptimal to psychological functioning.Self-compassion is another important self-related concept assumed to promote mental health and well-being.However,research on the relation of self-compassion to contingent self-esteem is lacking.Two studies were conducted to explore the role of selfcompassion,either as a personal characteristic or an induced mindset,in influencing the effects of contingent self-esteem on well-being.Study 1 recruited 256 Chinese college students(30.4%male,mean age=21.72 years)who filled out measures of contingent self-esteem,self-compassion,and well-being.The results found that self-compassion moderated the effect of contingent self-esteem on well-being.In Study 2,a sample of 90 Chinese college students(34%male,mean age=18.39 years)were randomly assigned to either a control or self-compassion group.They completed baseline trait measures of contingent self-esteem,self-compassion,and self-esteem.Then,they were led to have a 12-min break(control group)or listen to a 12-min self-compassion audio(self-compassion group),followed by a social stress task and outcome measures.The results demonstrated the effectiveness of the brief self-compassion training and its moderating role in influencing the effects of contingent self-esteem on negative affects after the social stress task.This research provides implications that to equip with a self-compassionate mindset could lower the risk of the impairment of well-being associated with elements of contingent selfesteem,which involves a fragile sense of self-worth.It may also provide insights into the development of an“optimal selfesteem”and the improvement of well-being. 展开更多

Background: Family members of Intensive Care Unit (ICU) patients are subject to a higher risk of depression, anxiety, and stress-related disorders. This psychological distress inevitably affects their perception of the quality of care that their relative receives. The aim of this study is to enlighten the effect of psychopathology, resilience, and self-compassion on the satisfaction of family members of ICU patients and examine the role of self-compassion and resilience as explaining variables of the psychopathology and satisfaction relation. Methods: One hundred and seventy-six family members participated in the study. Each participant completed the Symptom Check List 90 (SCL-90-R), the Family Satisfaction in the Intensive Care Unit (FS-ICU) questionnaire, the Connor-Davidson Mental Endurance Scale (CD-RISC), and the Self-Compassion scale (SCS). Analysis of variance and path analysis was applied in order to test the research hypotheses. Results: The patient’s age, patient’s gender, type of relation, and age of the family member did not have a statistically significant direct or interaction effect on the satisfaction of the family members. The psychopathology had a significant negative correlation with the total satisfaction of the family members. The self-compassion was found to have a significant direct effect on psychopathology and a significant indirect effect on satisfaction via resilience, while both resilience and self-compassion had significant direct or indirect effects on satisfaction. Self-compassion was found to eliminate the mediation role of resilience on psychopathology and the resilience and psychopathology effect on satisfaction. Conclusions: Self-compassion emerged as the most important personality characteristic concerning the satisfaction of family members of ICU patients. Our study indicates that interventions aiming to enhance self-compassion will help patients’ relatives cope with the particularly stressful experience of the intensive care unit. 展开更多

Self-compassion refers to a positive, kind attitude of a person toward oneself when confronted with difficulties. A self-compassionate coping style may buffer against the development of psychological problems. Aim was to introduce a new, 4-item measure for Self-compassion and to test its psychometric properties. In addition, its relationships with Neff’s Self Compassion Scale (SCS) and with the HADS depression and anxiety scales were studied, in an adult general population sample. The results showed that the SCCM had a high reliability, confirming internal validity. In addition, the SCCM was strongly related to all subscales and total score of the SCS, suggesting construct validity. Finally, also strong relationships were found with symptoms of depression and anxiety, suggesting criterion validity. The SCCM might therefore be considered a valuable and reliable tool in the study of self-compassion associated with mental-health problems, while it also might provide us with targets for intervention. 展开更多

Self-compassion is a new concept of self-awareness, and proper self-compassion has a positive role in promoting individual mental health. Due to the lack of good education and growth in junior high school, there is a great lack of non-intelligence factors in the current secondary vocational students. Therefore, it is of great significance to carry out "self-compassion" education. In education and teaching, it is necessary to guide students to correctly understand "self-compassion", help students to fully understand themselves, learn to accept themselves, correctly accept their own imperfections, and enable students to master some methods of "self-compassion" so as to promote students' healthy growth. 展开更多

Mason Reset(MR),a groundbreaking invention by Clesson E.Mason in 1930 that later became a part of“the universal approach to process control instrumentation”,is revisited in this paper and is shown to consists of three actions:fast(errorcorrection),medium(negative feedback for expanded proportional band)and slow(reset for zero steady-state error).The focus of the paper is on the reset action,generated from a positive feedback loop,and its underlying principles with profound implications to our understanding and practice of automatic control,both basic and advanced.For example,we note that reset control and integral control,contrary to common belief,differ fundamentally in design principle and in practicality.Such difference comes to a head in the event of integrator windup:while reset windup is a problem of actuator saturation,the integrator windup is a runaway situation due to controller instability.In fact,there is no advantage gained in replacing MR with an integrator.In other words,one should not integrate the error directly as in standard PID,since doing so makes the closed-loop system internally unstable.With MR-based control formulated in this paper,there is no such threat of instability and,therefore,no need for any anti-windup mechanisms.Furthermore,the integral control is made scalable in this framework as a tradeoff between the steady-state accuracy and the controller stability.This leads to a novel MR-based control design,scalable in gain and in time to accommodate various process characteristics and design specifications.Simple in construction and transparent in principle,this MR-based control,as a basic framework of design,is readily deployable in scale. 展开更多

An improved model based on you only look once version 8(YOLOv8)is proposed to solve the problem of low detection accuracy due to the diversity of object sizes in optical remote sensing images.Firstly,the feature pyramid network(FPN)structure of the original YOLOv8 mode is replaced by the generalized-FPN(GFPN)structure in GiraffeDet to realize the"cross-layer"and"cross-scale"adaptive feature fusion,to enrich the semantic information and spatial information on the feature map to improve the target detection ability of the model.Secondly,a pyramid-pool module of multi atrous spatial pyramid pooling(MASPP)is designed by using the idea of atrous convolution and feature pyramid structure to extract multi-scale features,so as to improve the processing ability of the model for multi-scale objects.The experimental results show that the detection accuracy of the improved YOLOv8 model on DIOR dataset is 92%and mean average precision(mAP)is 87.9%,respectively 3.5%and 1.7%higher than those of the original model.It is proved the detection and classification ability of the proposed model on multi-dimensional optical remote sensing target has been improved. 展开更多

Background The patient-reported Dimensional Anhedonia Rating Scale(DARS)has been adapted into Chinese,so there is a need to evaluate its measurement properties in a Chinese population.Aims To evaluate the reliability and validity of the DARS among Chinese individuals with major depressive disorder(MDD)and its treatment sensitivity in a prospective clinical study.Methods Data were from a multicentre,prospective clinical study(NCT03294525),which recruited both patients with MDD,who were followed for 8 weeks,and healthy controls(HCs),assessed at baseline only.The analysis included confirmatory factor analysis,validity and sensitivity to change.Results Patients’mean(standard deviation(SD))age was 34.8(11.0)years,with 68.7%being female.75.2%of patients with MDD had melancholic features,followed by 63.8%with anxious distress.Patients had experienced MDD for a mean(SD)of 9.2(18)months.DARS scores covered the full range of severity with no major floor or ceiling effects.Confirmatory factor analysis showed adequate fit statistics(comparative fit index 0.976,goodness-of-fit index 0.935 and root mean square error of approximation 0.055).Convergent validity with anhedonia-related measures was confirmed.While the correlation between the DARS and the Hamilton Depression Rating Scale was not strong(r=0.31,baseline),the DARS was found to differentiate between levels of depression.Greater improvements in DARS scores were seen with the Hamilton Rating Scale for Depression responder group(effect size 1.16)compared with the non-responder group(effect size 0.46).Conclusions This study comprehensively evaluated the measurement properties of the DARS using a Chinese population with MDD.Overall,the Chinese version of DARS demonstrates good psychometric properties and has been found to be responsive to change during antidepressant treatment.The DARS is a suitable scale for assessing patient-reported anhedonia in future clinical trials. 展开更多
