There is a general lack of consensus on the most appropriate treatment options for RS. AIM To summarize the literature on treatment options for RS. METHODS We conducted a systematic review according to PRISMA guidelines. We searched Medline (1946 to February 2019), EMBASE (1947 to February 2019), PsycINFO (1806 to February 2019) and Cochrane central register of controlled trials for articles discussing treatment options for adult patients (> 18 years) with RS. All relevant articles were accessed in full text. We extracted data on study designs, patient profiles, duration of symptoms, follow up periods, date, diagnostic criteria, interventions and outcomes. Risk of bias assessment was carried out independently by 3 reviewers via Cochrane Risk of Bias tool and Newcastle Ottawa Scale for randomized controlled trials and Cohort studies respectively. RESULTS Twelve articles were identified. A total of 254 patients were included in the analysis, with a mean age of 36.1 (range 18-89). 185 patients (72.8%) were females. 5 studies looked into behavioral therapies, primarily diaphragmatic breathing (DB) 2 studies looked at baclofen, 1 fundoplication and 1 supportive lifestyle changes. 3 studies looked at a combination of therapies involving pharmacological, behavioral and psychotherapies. CONCLUSION Although evidence for treatment options is still limited, the strongest evidence point towards the use of DB and Baclofen, and both should be considered depending on their availabilities.展开更多

Methods: A cross-sectional study was conducted between October 2017 and May 2018. A sample of 253 individuals who had experienced a traumatic event in the last two years, was included. Participants completed an online self-reported survey, including demographic variables, trauma characteristics, the German Posttraumatic Growth and Depreciation Inventory — Expanded, the Brief COPE Inventory, and the Event Related Rumination Inventory. An analysis of correlation, a principal component analysis and hierarchical regression analyses were conducted. Statistical analyses were undertaken on SPSS (version 25.0;IBM, New York, USA). Results: After controlling for the effects of personal and trauma characteristics, self-sufficient coping and socially supported coping were found to favor the emergence of PTG. Event-related and recent deliberate rumination were positively related to PTG. Avoidant-focused coping and recent intrusive rumination were positively associated with PTD. Overall, the final models accounted for 46% and 58% of the variance in PTG and PTD. Conclusion: Our findings confirm the PTG model and support the central role of deliberate rumination, self-sufficient coping and socially supported coping in the development of PTG. Our results indicate that a similar model of PTD with comparable influencing factors can be assumed: if the individual is stuck in ongoing intrusive rumination and uses more avoidance-focused coping, it might lead to more reports of PTD.展开更多

Adversity quotient is the adaptation ability to overcome problems and obstacles with a positive attitude. Early adolescence, as a critical stage of life, needs to cultivate adversity quotient. However, adversity quotient and its influencing factors in adolescents have not been fully understood. Methods: A total of 129 students from 3 junior high schools (grade 7-9) in Chon Buri province, Thailand, were randomly recruited to participate in this correlational research study. They completed 5 questionnaires including the demographic form, adversity quotient assessment, authoritative parenting style, optimism, and rumination. Descriptive statistics and Pearson’s correlation coefficient were used for data analysis. Results: Adversity quotient was at a moderate level with a mean of 138.78 (standard deviation [SD] = 21.25). Adversity quotient was significantly, positively correlated with authoritative parenting at the highest level (r = 0.60), followed by optimism at a moderate level (r = 0.38), and rumination at a low level (r = 0.25, P < 0.01). Conclusions: All parties responsible for early adolescents’ development should enhance the adversity quotient to a higher level through campaigns promoting authoritative parenting and optimism. An unexpected positive correlation between adversity quotient and rumination warrants cautious interpretation and more studies.展开更多

文摘BACKGROUND Non-suicidal self-injury(NSSI)is common among adolescents with depressive disorders and poses a major public health challenge.Rumination,a key cognitive feature of depression,includes different subtypes that may relate to NSSI through distinct psychological mechanisms.However,how these subtypes interact with specific NSSI behaviors remains unclear.AIM To examine associations between rumination subtypes and specific NSSI behaviors in adolescents.METHODS We conducted a cross-sectional study with 305 hospitalized adolescents diagnosed with depressive disorders.The subjects ranged from 12-18 years in age.Rumi-nation subtypes were assessed using the Ruminative Response Scale,and 12 NSSI behaviors were evaluated using a validated questionnaire.Network analysis was applied to explore symptom-level associations and identify central symptoms.RESULTS The network analysis revealed close connections between rumination subtypes and NSSI behaviors.Brooding was linked to behaviors such as hitting objects and burning.Scratching emerged as the most influential NSSI symptom.Symptomfocused rumination served as a key bridge connecting rumination and NSSI.CONCLUSION Symptom-focused rumination and scratching were identified as potential intervention targets.These findings highlight the psychological significance of specific cognitive-behavioral links in adolescent depression and suggest directions for tailored prevention and treatment.However,the cross-sectional,single-site design limits causal inference and generalizability.Future longitudinal and multi-center studies are needed to confirm causal pathways and verify the generalizability of the findings to broader adolescent populations.

文摘BACKGROUND Rumination is a critical psychological factor contributing to the relapse of major depressive episodes(MDEs)and a core residual symptom in remitted MDEs.Investigating its neural correlations is essential for developing strategies to prevent MDE relapse.Despite its clinical importance,the brain network mechanisms underlying rumination in remitted MDE patients have yet to be fully elucidated.AIM To investigate the brain network mechanism underlying rumination in patients with remitted MDEs using functional magnetic resonance imaging(fMRI).METHODS We conducted an fMRI-based rumination-distraction task to induce rumination and distraction states in 51 patients with remitted MDEs.Functional connectivity(FC)was analyzed using the network-based statistic(NBS)approach,and eight topological metrics were calculated to compare the network topological properties between the two states.Correlation analyses were further performed to identify the relationships between individual rumination levels and the significantly altered brain network metrics.RESULTS The NBS analysis revealed that the altered FCs between the rumination and distraction states were located primarily in the frontoparietal,default mode,and cerebellar networks.No significant correlation was detected between these altered FCs and individual rumination levels.Among the eight topological metrics,the clustering coefficient,shortest path length,and local efficiency were significantly lower during rumination and positively correlated with individual rumination levels.In contrast,global efficiency was greater in the rumination state than in the distraction state and was negatively correlated with individual rumination levels.CONCLUSION Our work revealed the altered FC and topological properties during rumination in remitted MDE patients,offering valuable insights into the neural mechanisms of rumination from a brain network perspective.
文摘The objective of this study was to characterize the rumination time in lactating dairy cows fed with corn silage.Rumination time was recorded 24 h/day using direct visual observation.Six trials were conducted during 2018,2019 and 2020,and rumination time was recorded in 480-2-hour periods from 40 Holstein Friesian cows.In each trial,6 or 8 cows were selected and balanced for days in milk(DIM),milk production and number of lactations.Each cow was recorded continuously for periods of 2 h at a time to complete a full 24-h period per week(12 values per day).Data from all cows were associated with 4 reproductive statuses of cows:Inseminated(1-45 days after insemination),Open(45-150 days after calving),not-pregnant and pregnant.The longest rumination time(RT)was found in pregnant cows(average 536.9±29.87 min/day),and the shortest RT was in open cows(average 420.3±63.2 min/day).Inseminated and non-pregnant cows were found with intermediate values(527.3±82.4 min/day and 467.1±30.7 respectively).Significantly different RT means were found between pregnant and open cows(p<0.0001),pregnant vs.inseminated cows(p<0.0001),and between inseminated and open cows(p=0.0005).We concluded that some gynecological conditions of lactating cows affect the RT.Measurement of RT by visual observations proved to be acceptable for the conditions of this study when cows were housed indoors and were fed with partial mixed ration(PMR)based on corn silage.

文摘Background Previous investigations into the effect of dietary forage on calf performance have been inconsistent,and there is a paucity of information exploring the effect of age on the growth performance and rumination of calves.Eighty-four female Holstein calves(41.5±4.2 kg)were enrolled at birth,a subset of the calves were fed calf starter only(CON,n=21)while the rest(n=63)were classified into three treatment groups:the early(EHAY,n=26,5.1±0.8 d),the middle(MHAY,n=21,7.9±0.8 d)and the late(LHAY,n=16,12.1±1.4 d)hay consumers.The short-term effect of the age at first forage consump-tion(AFF)on calves’feed intake was monitored until d 84.In addition,the long-term effects of AFF on body weight,structural growth and rumination behavior were recorded until d 196.Rumen samples were collected on d 1,7,35,84 and 196 to ana-lyze the rumen fermentation,while fecal samples were collected from d 78 to 84 to estimate digestibility parameters.Results Treatment had no effect on feed intake.While,the EHAY calves tended to have lower BW and ADG compared to LHAY and CON calves.Several total-tract apparent digestibility parameters and digestible nutrients intake were significantly lower in EHAY calves compared with CON and LHAY calves.Calves in the EHAY group tended to begin ruminating ealier,while CON calves were the latest(12.3 vs.15.5 days of age).A treatment and time interaction was present for rumination time due to greater rumination in calves consuming hay compared to CON calves in week 10 to 12,the differences in rumination disappeared afterwards,no long-lasting significant differences in the rumina-tion and rumen fermentation parameters were found between treatments.Conclusions In conclusion,this study showed that hay consumption earlier in life(in the first week,around 5 days of life)could negatively affect the growth of the calf in the short and long term.Compared to consuming hay from the second week(around 12 days of life)or feeding concentrate only without hay,starting to consume hay from the first week could compromise nutrient digestibility and digestible nutrient intake independent of developing rumination behaviour and rumen fermentation.
文摘AIM To explore the association between metacognitive beliefs,rumination and shyness in a non-clinical sample of adults.METHODS One hundred and three healthy subjects from the general population were enrolled in the study.Shyness was evaluated using the Revised Cheek and Buss Shyness Scale,rumination was assessed using the Ruminative Response Scale,metacognition was evaluated using the MetaCognitions Questionnaire 30,and anxiety levels were measured using the State Trait Anxiety Inventory form Y.Correlation analyses,mediation models and 95%bias-corrected and accelerated(BCaCI)bootstrapped analyses were performed.Mediation analyses were adjusted for sex and anxiety.RESULTS Shyness,rumination and metacognition were significantly correlated(P<0.05).The relationship between metacognition and shyness was fully mediated by rumination(Indirect effect:0.20;95%BCaCI:0.08-0.33).CONCLUSION These findings suggest an association between metacognition and shyness.Rumination mediated the relationship between metacognition and shyness,suggesting that rumination could be a cognitive strategy for shy people.Future research should explore the relationship between these constructs in more depth.
文摘BACKGROUND Illness perception has long been hypothesized to be linked to psychological well-b eing in patients with rheumatic diseases,although substantial evidence is lacking,and the contribution of ruminative coping style to this relationship is unclear.AIM To investigate the roles of illness perception and rumination in predicting fatigue and negative emotions in patients with chronic rheumatic diseases.METHODS Illness perception,rumination,fatigue and negative emotions(i.e.depression,anxiety and stress)were assessed by the Illness Perception Questionnaire-Revised,Stress Reactive Rumination Scale,Multidimensional Assessment of Fatigue,and the Depression,Anxiety and Stress Scale respectively.Multivariate regression analysis,the Sobel test,and the bootstrap were used to identify the mediating effect of rumination.RESULTS All five subscales of illness perception,including perceived illness identity,chronicity,cyclical nature,consequences and coherence of illness,were significantly associated with fatigue and negative emotions.In mediational analysis,rumination was found to mediate three components of illness perception(the identity,cyclical nature and consequences of illness)and negative emotions/fatigue.CONCLUSION Perceived identity,cyclical nature,and consequences of illness are significantly associated with fatigue and negative emotions in patients with chronic rheumatic diseases and these associations are mediated by rumination.Our findings suggest that psychological intervention should target rumination to improve physical and emotional well-being of patients with chronic rheumatic diseases.
文摘BACKGROUND Rumination syndrome (RS) is characterized by recurrent effortless postprandial regurgitation of recently ingested food from the stomach to the oral cavity and has been associated with quality of life impairment and malnutrition. There is a general lack of consensus on the most appropriate treatment options for RS. AIM To summarize the literature on treatment options for RS. METHODS We conducted a systematic review according to PRISMA guidelines. We searched Medline (1946 to February 2019), EMBASE (1947 to February 2019), PsycINFO (1806 to February 2019) and Cochrane central register of controlled trials for articles discussing treatment options for adult patients (> 18 years) with RS. All relevant articles were accessed in full text. We extracted data on study designs, patient profiles, duration of symptoms, follow up periods, date, diagnostic criteria, interventions and outcomes. Risk of bias assessment was carried out independently by 3 reviewers via Cochrane Risk of Bias tool and Newcastle Ottawa Scale for randomized controlled trials and Cohort studies respectively. RESULTS Twelve articles were identified. A total of 254 patients were included in the analysis, with a mean age of 36.1 (range 18-89). 185 patients (72.8%) were females. 5 studies looked into behavioral therapies, primarily diaphragmatic breathing (DB) 2 studies looked at baclofen, 1 fundoplication and 1 supportive lifestyle changes. 3 studies looked at a combination of therapies involving pharmacological, behavioral and psychotherapies. CONCLUSION Although evidence for treatment options is still limited, the strongest evidence point towards the use of DB and Baclofen, and both should be considered depending on their availabilities.
文摘[Objective]Real-time monitoring of cow ruminant behavior is of paramount importance for promptly obtaining relevant information about cow health and predicting cow diseases.Currently,various strategies have been proposed for monitoring cow ruminant behavior,including video surveillance,sound recognition,and sensor monitoring methods.How‐ever,the application of edge device gives rise to the issue of inadequate real-time performance.To reduce the volume of data transmission and cloud computing workload while achieving real-time monitoring of dairy cow rumination behavior,a real-time monitoring method was proposed for cow ruminant behavior based on edge computing.[Methods]Autono‐mously designed edge devices were utilized to collect and process six-axis acceleration signals from cows in real-time.Based on these six-axis data,two distinct strategies,federated edge intelligence and split edge intelligence,were investigat‐ed for the real-time recognition of cow ruminant behavior.Focused on the real-time recognition method for cow ruminant behavior leveraging federated edge intelligence,the CA-MobileNet v3 network was proposed by enhancing the MobileNet v3 network with a collaborative attention mechanism.Additionally,a federated edge intelligence model was designed uti‐lizing the CA-MobileNet v3 network and the FedAvg federated aggregation algorithm.In the study on split edge intelli‐gence,a split edge intelligence model named MobileNet-LSTM was designed by integrating the MobileNet v3 network with a fusion collaborative attention mechanism and the Bi-LSTM network.[Results and Discussions]Through compara‐tive experiments with MobileNet v3 and MobileNet-LSTM,the federated edge intelligence model based on CA-Mo‐bileNet v3 achieved an average Precision rate,Recall rate,F1-Score,Specificity,and Accuracy of 97.1%,97.9%,97.5%,98.3%,and 98.2%,respectively,yielding the best recognition performance.[Conclusions]It is provided a real-time and effective method for monitoring cow ruminant behavior,and the proposed federated edge intelligence model can be ap‐plied in practical settings.
文摘Objective:To evaluate the nursing effect of self-help mindfulness therapy for patients with depression.Methods:120 cases of depression patients admitted to the Department of Psychosomatic Disorders of our hospital between January 2020 and January 2023 were selected.After being grouped by the random draw method,60 cases in the observation group adopted self-help mindfulness therapy and 60 cases in the control group adopted conventional nursing care,the nursing effects were subsequently compared.Results:Before nursing,there was no difference in the comparison of clinical symptom scores,rumination scores,positive psychological scores,and self-esteem scores between the two groups(P>0.05).After nursing,the clinical symptom scores of the observation group were lower than those of the control group;the rumination scores were lower than those of the control group;the positive psychological scores were higher than those of the control group;and the self-esteem scores were higher than those of the control group,and all of them were statistically significant(P<0.05).Conclusion:Self-help mindfulness therapy can improve the clinical symptoms of patients with depression and their rumination,and enhance their positive psychological state and self-esteem level,which has high nursing advantages.

文摘Rumination is closely related to ruminant’s health and welfare,so it is very important to monitor rumination.Rumination monitoring equipment based on chewing and swallowing audio is easy to be affected by ambient noise,equipment based on acceleration sensor is not easy to monitor number of cuds and other information,equipment based on video monitoring has high cost and is easy to be affected by weather and other cows,while equipment based on chewing pressure can accurately record the chewing pressure of dairy cows,and use related processing technology to obtain the number of cuds and other information.In the related research,the peak value and interval of masticatory pressure peak in time domain were used to identify rumination.In view of the problem that the standard of pressure peak was not well defined due to the different head size and masticatory strength of different age and different breed cows,this paper proposed a method to identify the number of rumination,duration of rumination and number of cuds of cows by using standard deviation and noseband pressure signal frequency spectrum.The accurate and stable frequency spectrum range of rumination noseband pressure signal was obtained by frequency spectrum analysis,and the interference of feeding noseband pressure signal to rumination noseband pressure signal was eliminated by using standard deviation.Compared with the direct observation,the results showed that the recognition accuracy of the method proposed in this paper were 100%,94.2%and 94.45%for the number of rumination,duration of rumination and number of cuds respectively,and the average absolute errors were 0,2.0029%and 2.5623%respectively,which showed that the method can accurately identify the rumination information of dairy cows.
文摘Purpose: The present study examined the joint impact of coping and rumination after trauma on posttraumatic growth (PTG) and posttraumatic depreciation (PTD) based on the PTG model. Methods: A cross-sectional study was conducted between October 2017 and May 2018. A sample of 253 individuals who had experienced a traumatic event in the last two years, was included. Participants completed an online self-reported survey, including demographic variables, trauma characteristics, the German Posttraumatic Growth and Depreciation Inventory — Expanded, the Brief COPE Inventory, and the Event Related Rumination Inventory. An analysis of correlation, a principal component analysis and hierarchical regression analyses were conducted. Statistical analyses were undertaken on SPSS (version 25.0;IBM, New York, USA). Results: After controlling for the effects of personal and trauma characteristics, self-sufficient coping and socially supported coping were found to favor the emergence of PTG. Event-related and recent deliberate rumination were positively related to PTG. Avoidant-focused coping and recent intrusive rumination were positively associated with PTD. Overall, the final models accounted for 46% and 58% of the variance in PTG and PTD. Conclusion: Our findings confirm the PTG model and support the central role of deliberate rumination, self-sufficient coping and socially supported coping in the development of PTG. Our results indicate that a similar model of PTD with comparable influencing factors can be assumed: if the individual is stuck in ongoing intrusive rumination and uses more avoidance-focused coping, it might lead to more reports of PTD.

文摘Rumination,as a clinical manifestation and pathogenic factor of depression,has long been the focus of psycho-logical research regarding its causes and ameliorating approaches.Behavioral studies have shown that rumina-tion is related to inhibitory control deficits,which provides ideas for reducing it.However,the neural relationship between them has not been clearly discussed.In this study,we first used multi-level kernel density analysis to conduct two meta-analyses of published functional magnetic resonance imaging studies:one was rumination comprising 17 studies with 180 foci,and the other was inhibitory control comprising 205 studies with 3791 foci.Conjunction analysis was then performed to explore the common brain regions and further decode them through Neurosynth to confirm the cognitive specificity.Results showed that rumination was mainly related to the default mode network(DMN),while inhibitory control was associated with the frontoparietal network(FPN).In addition,the common activation areas were mainly concentrated in the bilateral precuneus,right supe-rior frontal gyrus,bilateral median cingulate,paracingulate gyri,and the left triangular part of inferior frontal gyrus(IFG).Decoding results also revealed they were involved in inhibition,memory retrieval,and self-related processes.Our findings support that rumination is associated with inhibitory control and can be explained neu-rologically by an antagonistic relationship between the DMN and FPN.In sum,inhibitory control may be related to rumination via inhibiting task-unrelated attention and controlling self-related processing.This research will help us understand and predict rumination from the perspective of inhibitory control and reduce rumination through behavioral training of inhibitory control or the application of neuromodulation techniques to common activation regions.

文摘Information about dairy cow ruminating is closely associated with the health status of dairy cows.Therefore,it is of great significance to recognize and make statistics of dairy cows’ruminating and feeding behavior.Concerning conventional recognition methods which are dependent on contact type devices,they have some defects of poor instantaneity and strong stress responses.As for recognition based on machine vision,it needs to transmit masses of data and raises high requirements for the cloud server and network performance.According to principles of edge computing,the model is deployed via Tensorflow.js in an edge device in the present study,constructing a recognition and statistical system for ruminating and feeding behavior of dairy cows.Through the application programming interface(API)of the browser,an edge device is able to invoke a camera and acquire dairy cow images.Then,the images can be inputted in the SSD MobileNet V2 model,which is followed by inference based on browser hashrate.Moreover,the edge device merely uploads recognition results to the cloud server for statistics,which features high instantaneity and compatibility.In terms of recognizing ruminating and feeding behavior of dairy cows,the proposed system has a precision ratio of 96.50%,a recall rate of 91.77%,an F1-score of 94.08%,specificity of 91.36%,and accuracy of 91.66%.This suggests that the proposed method is effective in recognizing dairy cow behavior.

文摘This study was to investigate growth performance,rumination development,rumen fermentation and feed digestion in young calves provided high volumes(about 20%of calf birth weight)of milk with or without forage inclusion and how these parameters correlate with each other.Immediately after birth,160 newborn Holstein female calves(41.6±4.2 kg of initial BW)were randomly divided into 2 treatments:1)starter(CON,only starter)and 2)starter and hay(HAY,both starter and hay).The calves were fed their respective experimental diets from d 4 to 84,after which they were all introduced to similar diets until the end of the experiment on d 196.Treatment had no effect on growth and structural measurements throughout the experimental period.However,treatment had an effect on the other parameters,mainly during the post-weaning period.Forage supplementation tended to reduce starter dry matter intake(P=0.05),while increasing the forage intake(P<0.01)and the feed-to-gain ratio(P<0.01).HAY calves had increased neutral detergent fiber(NDF)and physically effective NDF(peNDF)intakes(P<0.05)and tended to lower(P<0.01)starch intake compared to CON calves.The HAY calves had a higher rumination time(P<0.01),ruminal pH(P<0.01),and acetate-to-propionate ratio(P=0.05)compared to the CON calves.Spearman correlation analysis showed that rumination time was positively related to the ruminal p H at d 84(P=0.01)and 196(P=0.02).The HAY calves had similar apparent total-tract digestibility of dry matter(DM),NDF and ether extract(EE),but lower digestibility of organic matter(OM,P=0.03),crude protein(CP,P<0.01)and starch(P<0.01)compared to those of the CON calves at week 12.Furthermore,there were no positive relationships between rumination time and nutrient digestibility or between rumination time per kilogram DM and nutrient digestibility.In conclusion,feeding hay to calves fed a high milk level improved rumination during the post-weaning period only,without a concomitant effect on growth performance throughout the experimental period,suggesting no detrimental effect of feeding forage in calves fed high milk level.

文摘Background:Rumination is a transdiagnostic psychological process that plays a prominent role in many common psychiatric disorders,albeit its neurophysiological basis remains elusive.Existing neuroimaging studies have highlighted the precuneus and hippocampus as two pivotal brain regions in rumination’s neural underpinnings.Methods:Here,we examined the intracranial electroencephalogram(iEEG)recordings from 21 patients with epilepsy during a naturalistic,continuous,active rumination state and measured the low frequency(1-8 Hz)and high gamma(70-150 Hz)band oscillation powers.Results:We observed enhanced low-frequency power in the precuneus and reduced high gamma power in the hippocampus during the rumination condition compared to the control condition.The hippocampal high gamma power reduction was associated with the self-reported reflection tendency.Conclusions:Our findings provided empirical evidence of the neurophysiological underpinnings of rumination and implicated a precuneus-hippocampus coupling across neural oscillation bands during an active rumination state.

文摘In order to realize the automatic monitoring of ruminant activities of cows,an automatic detection method for the mouth area of ruminant cows based on machine vision technology was studied.Optical flow was used to calculate the relative motion speed of each pixel in the video frame images.The candidate mouth region with large motion ranges was extracted,and a series of processing methods,such as grayscale processing,threshold segmentation,pixel point expansion and adjacent region merging,were carried out to extract the real area of cows’mouth.To verify the accuracy of the proposed method,six videos with a total length of 96 min were selected for this research.The results showed that the highest accuracy was 87.80%,the average accuracy was 76.46%and the average running time of the algorithm was 6.39 s.All the results showed that this method can be used to detect the mouth area automatically,which lays the foundation for automatic monitoring of cows’ruminant behavior.
文摘Objectives:To explore the approaches for reducing non-suicidal self-injury(NSSI)behaviors in Chinese adolescents,the present study investigated the association between parent-child conflict and NSSI in adolescents,while also examining the mediating role of depression and the moderating role of rumination thinking.Methods:A cluster sampling method was employed to select 1227 Chinese adolescents aged 12 to 18 as participants,who completed measures including the Parent-Child conflict,Depression,Rumination Thinking,and Non-Suicidal Self-Injury questionnaires.The present study used SPSS 26.0 to conduct the Descriptive statistics,correlation analysis,and reliability tests,and PROCESS 3.3 to test the hypothesis model.Results:(1)There is a positive correlation between parent-child conflict and NSSI in adolescents;(2)Depression mediates the relationship between parent-child conflict and NSSI in adolescents;(3)Rumination thinking acts as a moderator in the association between parent-child conflict and depression.This study finds the indirect effect of depression on NSSI behaviors among Chinese adolescents.Furthermore,the study also finds protective factors by examining the role of reducing individual rumination thinking in mitigating negative emotions following adverse experiences.In conclusion,this research provides a pathway and foundation for enhancing interventions targeting NSSI behaviors among Chinese adolescents.Conclusion:The relationship between parent-child conflict and NSSI in adolescents is positively correlated.Depression acts as a mediator in the association between parent-child conflict and NSSI in adolescents.The effect of parent-child conflict on NSSI is positively moderated by rumination thinking.Specifically,low-level rumination thinking may mitigate the negative impact of parent-child conflict on depression.

文摘The present study examined the role of emotional balance and the moderating role of rumination in the relationship between psychological inflexibility and sleep quality among college students.Participants were 837 Chinese college students(females=52%,mean age=18.89,SD=0.93 years).They completed the Multidimensional Psychological Inflexibility Scale(MPIS),Affect Balance Scale(ABS),Ruminative Response Scale(RRS),Pittsburgh Sleep Quality Index(PSQI).We utilized moderated-mediation analysis to explore the mechanism of action among variables.Emotional balance mediated the relationship between psychological inflexibility and sleep quality,and rumination moderated the direct effect of psychological inflexibility on sleep quality and the mediating effect of emotional balance.Specifically,the direct effect of psychological inflexibility on sleep quality and the mediating effect of emotional balance increased with the increase in rumination level.High levels of rumination in individuals exacerbate the negative effects of psychological inflexibility on sleep quality.It also enhances the disruption of psychological inflexibility on the individual’s emotional balance ability,which leads to poorer sleep quality.The results contribute to the evidence of how psychological inflexibility explains the sleep quality of college students and how sleep quality can be improved by psychological inflexibility interventions,rumination interventions,and emotional balance interventions.Student development services should provide targeted students’sleep quality counseling for the promotion and maintenance of college students’physical and mental health.

文摘Objectives: To determine the level of adversity quotient and its associations with rumination, optimism, and authoritative parenting style in junior high school students. Adversity quotient is the adaptation ability to overcome problems and obstacles with a positive attitude. Early adolescence, as a critical stage of life, needs to cultivate adversity quotient. However, adversity quotient and its influencing factors in adolescents have not been fully understood. Methods: A total of 129 students from 3 junior high schools (grade 7-9) in Chon Buri province, Thailand, were randomly recruited to participate in this correlational research study. They completed 5 questionnaires including the demographic form, adversity quotient assessment, authoritative parenting style, optimism, and rumination. Descriptive statistics and Pearson’s correlation coefficient were used for data analysis. Results: Adversity quotient was at a moderate level with a mean of 138.78 (standard deviation [SD] = 21.25). Adversity quotient was significantly, positively correlated with authoritative parenting at the highest level (r = 0.60), followed by optimism at a moderate level (r = 0.38), and rumination at a low level (r = 0.25, P < 0.01). Conclusions: All parties responsible for early adolescents’ development should enhance the adversity quotient to a higher level through campaigns promoting authoritative parenting and optimism. An unexpected positive correlation between adversity quotient and rumination warrants cautious interpretation and more studies.
