BACKGROUND Irritable bowel syndrome(IBS)is a common digestive system disease with a high incidence rate and is common in women.The cause of IBS remains unclear.Some studies have shown that mental and psychological diseases are independent risk factors for IBS.At present,the treatment of IBS is mainly symptomatic treatment.Clinically,doctors also use cognitive behavioral therapy to improve patients'cognitive ability to diseases and clinical symptoms.In recent years,exercise therapy has attracted more and more attention from scholars.Improving the symptoms of IBS patients through psychosomatic treatment strategy may be a good treatment method.AIM To explore the effects of an intervention of cognitive behavioral therapy combined with exercise(CBT+E)on the cognitive bias and coping styles of patients with diarrhea-predominant irritable bowel syndrome(IBS-D);and to provide a theoretical reference for the management of IBS.METHODS Sixty IBS-D patients and thirty healthy subjects were selected.The 60 IBS-D patients were randomly divided into experimental and control groups.The experimental group was treated with the CBT+E intervention,while the control group was treated with conventional drugs without any additional intervention.The cognitive bias and coping styles of the participants were evaluated at baseline and after 6 wk,12 wk and 24 wk using the Automatic Thoughts Questionnaire(ATQ),Dysfunctional Attitudes Scale(DAS)and Pain Coping Style Questionnaire(CSQ)instruments,and the intervention effect was analyzed using SPSS 17.0 statistical software.RESULTS At baseline,the scores on the various scales showed that all subjects had cognitive bias and adverse coping styles.The IBS Symptom Severity Scale(IBSSSS)scores,ATQ total scores,DAS scores and CSQ scores of the two groups were not significantly different(P>0.05).Compared with baseline,after 6 wk of the CBT+E intervention,there were significant differences in the ATQ scores,the dependence and total scores on the DAS,and the catastrophization,distraction and prayer scores on the CSQ(P<0.05).After 12 wk,there were significant differences in the scores for perfectionism on the DAS and in the scores for reinterpretation,neglect and pain behavior on the CSQ in the experimental group(P<0.05).After 24 wk,there were significant differences in the vulnerability,dependence,perfectionism,and total scores on the DAS and in the catastrophization,distraction and prayer scores on the CSQ in the experimental group(P<0.01).The IBS-SSS scores were negatively correlated with the ATQ and DAS total scores(P<0.05)but were positively correlated with the CSQ total score(P<0.05).CONCLUSION Intervention consisting of CBT+E can correct the cognitive bias of IBS-D patients and eliminate their adverse coping conditions.CBT+E should be promoted for IBS and psychosomatic diseases. 展开更多

BACKGROUND The use of antidepressant therapy alone has a limited efficacy in patients with childhood trauma-associated major depressive disorder(MDD).However,the effectiveness of antidepressant treatment combined with psychodrama in these patients is unclear.AIM To evaluate the effectiveness of antidepressant treatment combined with psychodrama.METHODS Patients with childhood trauma-associated MDD treated with antidepressants were randomly assigned to either the psychodrama intervention(observation group)or the general health education intervention(control group)and received combination treatment for 6 mo.The observation group received general health education given by the investigator together with the“semi-structured group intervention model”of Yi Shu psychodrama.A total of 46 patients were recruited,including 29 cases in the observation group and 17 cases in the control group.Symptoms of depression and anxiety as well as coping style and resting-state functional magnetic resonance imaging were assessed before and after the intervention.RESULTS Symptoms of depression and anxiety,measured by the Hamilton Depression Scale,Beck Depression Inventory,and Beck Anxiety Inventory,were reduced after the intervention in both groups of patients.The coping style of the observation group improved significantly in contrast to the control group,which did not.In addition,an interaction between treatment and time in the right superior parietal gyrus node was found.Furthermore,functional connectivity between the right superior parietal gyrus and left inferior frontal gyrus in the observation group increased after the intervention,while in the control group the connectivity decreased.CONCLUSION This study supports the use of combined treatment with antidepressants and psychodrama to improve the coping style of patients with childhood trauma-associated MDD.Functional connectivity between the superior parietal gyrus and inferior frontal gyrus was increased after this combined treatment.We speculate that psychodrama enhances the internal connectivity of the cognitive control network and corrects the negative attention bias of patients with childhood trauma-associated MDD.Elucidating the neurobiological features of patients with childhood trauma-associated MDD is important for the development of methods that can assist in early diagnosis and intervention. 展开更多

Individual learners possess distinctive cognitive styles which have a great effect on foreign language learning. The present paper intends to study the relationship between foreign language learning proficiency and cognitive styles from the perspectives of psychology, psycholinguistics, and second language acquisition. Through the analysis, the author has arrived at a conclusion that learners with different cognitive styles adopt quite different strategies in learning a foreign language. The best-matched methods fitting for different cognitive styles may help learners improve their learning proficiency. Therefore, in order to improve teaching proficiency, foreign language teachers should keep a match between learners' cognitive styles and teaching methodologies. 展开更多

In this paper, we conduct theoretical research on British and American literature research and development trend based on cognitive theory and style analysis. Literature as a form of historical culture, the culture of different era, can better reflect the social culture background. Into contact with the cultural background of English-speaking countries, for teachers of English teaching and students' English learning has great significance. Under the basic influence of cultural background in English countries, learning English, will quickly understand the characteristics of syntax and understand the charm of language. Works covered by historical background, English can help students experience a good text artistic conception, thus extended thinking. Under this background, we integrate the basic cognitive theory and style analysis to propose the literature research and development trend that will assist the English community to find better developmental orientation. 展开更多

Since Henry Holec first put forward the term‘Autonomy'in 1980's, autonomous learning has been drawing the universal attention of scholars both at home and abroad. Promoting learners' ability of self-regulated learning has been taken as one of the important goals of modern education. College English autonomous learning based on network environment does not mean free study without any restraints or monitoring, but rather involves the self-monitoring and external monitoring. Meanwhile, different learners may have different cognitive styles in their learning processes, which may have an influence on the improvement of the learners' efficiency in the autonomous language learning. Proper monitoring models coordinating with the students' different field cognitive styles. 展开更多

Purpose: Based on a quasi-experimental design, this study sought to investigate the effects of two different cognitive styles, field independence and field dependence, on students' learning behaviors of online database search strategies.Design/methodology/approach: An experiment was carried out among senior students in a Chinese university.Findings: The field independent(FI) subjects performed better in terms of their search strategy scores. When comparing how many people in each cognitive style group learned the targeted search strategies, more field dependent(FD) subjects were successors, whereas the FI subjects were more inclined to learn from their past experience. When analyzing the reasons for the subjects' selection of search strategies, we found that the FI subjects demonstrated more rational thinking behaviors than the FD subjects.Research limitations: Only 28 students participated in the study, which was a relatively small sample size. A larger sample will give more information and therefore more precise results.Practical implications: This research can provide some suggestions to the information system designers on how the system interface can be better designed to suit the cognitive styles of different users.Originality/value: So far, few studies have been published about the effects of users' cognitive styles on their learning behaviors of online database search strategies. 展开更多

Objective: To investigate the effects of cognitive behavioral intervention on psychological stress response in breast cancer patients by cognitive behavioral intervention in breast cancer patients. Methods: Adopting the random comparison method, 100 patients with breast cancer were divided into comparison group and intervention group by 50 cases. The intervention group underwent cognitive behavioral intervention at the same time as the comparison group only received conventional treatment without cognitive behavioral intervention. Two groups of breast cancer patients were enrolled in the general questionnaire, the Self-Rating Anxiety Scale (SAS), and the Medical Coping Modes Questionnaire (MCMQ) within one week after admission and one month after treatment to understand the psychological stress levels of the two groups. Results: There was no significant difference in the scores of SAS and MCMQ between the intervention group and the comparison group before intervention (P > 0.05). But after intervention, the scores of SAS and MCMQ in the comparison group were significantly higher than those in the intervention group (P 0.05). It shows that the implementation of cognitive behavioral intervention therapy for breast cancer patients has the effect of improving their psychological status. Conclusion: Cognitive behavioral intervention therapy combined with psychology for breast cancer patients can effectively reduce their stress level, improve mental health status and improve their positive coping ability. 展开更多

Communication is vital for construction safety, but how it influences unsafe behavior in the work-place remains unclear. This study aims to explore the relationships between communication, cognitive failure, and unsafe behaviors in order to clarify those mechanics. We defined communication as management input, worker cognitive failure as process, and actual behaviors as management output. We collected data from three Chinese steel construction crews and utilized experience/behavior sampling and questionnaire surveys to collect project information. Bivariate statistical analyses were conducted to explain how communication affected unsafe behavior. The results showed that, rather than communication frequency, management communication style was significantly related to worker cognitive failure;specifically, communication style was related to perception of convenience and self-capacity, which could be upstream factors explaining unsafe behavior at the construction jobsite. This research provided statistical evidence supporting the hypothesized association among safety communication, cognitive failure, and behavior, bridging the missing gaps of previous research. Nonetheless, readers should interpret the results cautiously because of the limitations listed as follows. First, sample size is relatively small. In addition, crew turnover may mediate the relationship between communication and safe behaviors therefore, the impact of communication on cognitive failure can be blurred and a longitudinal study on specific crews working on the same job site could be used to evaluate it. Third, future research should focus on communication style, as it directly relates to the human cognitions that affect unsafe behavior at construction sites. 展开更多

Objective: To explore the effect of cognitive behavioral intervention therapy on the cellular immune function of patients undergoing radical mastectomy for the first time, and to provide a scientific basis for improving the treatment of breast cancer patients. Methods: 100 patients with breast cancer who were eligible for admission to the Department of Breast Surgery, Hainan Provincial People’s Hospital from January 2016 to December 2017 were selected as subjects. It is the first time to improve the radical mastectomy. They were randomly divided into control group and intervention group, 50 cases each. The control group used conventional treatment and routine care. On the basis of this, the intervention group conducted cognitive behavioral interventions including cognitive reconstruction and behavioral therapy. The patients were measured for serum IL-2, IL-4, IL-6, IL-8 and TNF-α levels on the second day after admission and three months after discharge. The changes of serum IL-2, IL-4, IL-6, IL-8 and TNF-α levels in the two groups were compared before and after cognitive intervention. Results: The concentrations of IL-2, IL-4, IL-6, IL-8 and TNF-α in the serum of the intervention group and the control group before intervention were compared. The difference was not statistically significant (P > 0.05). After the intervention, the serum levels of IL-2, IL-4 and IL-8 in the intervention group were lower than before the intervention. The concentration of TNF-α was higher than before the intervention. The difference was statistically significant (P Conclusion: Cognitive behavioral intervention therapy can change the levels of IL-2, IL-4, IL-6, IL-8 and TNF-α in serum of breast cancer patients. It has a positive effect on the regulation of immune function in breast cancer patients. 展开更多

A cognitive interpretation of the basic translation strategy, domestication and foreignization, is elaborated in this paper. It is pro posed that based on differences in linguistic presentation and cultural connotation, the application of translation strategy is determined by the style of the source text (ST) and the translator's performance, both of which are generated from individualized style of construe, decided by a range of experiences. So great importance should be attached to experience and construe. Such an interpretation is proposed to pro vide a new perspective to study translation strategy and initiate a better comprehension of the ST and translation. 展开更多

Given the ongoing character of COVID-19, higher-education students encountered multifaceted pressures brought about by thepandemic and had to overcome many difficulties during this period. Accordingly, it is imperative to identify the factors that mayhave protective effects on the social functioning and mental status of college students in the aftermath of COVID-19. This crosssectional study sought to ascertain the internal mechanism of positive coping (PC) styles affecting post-traumatic growth (PTG)and considered the mediating roles of cognitive reappraisal (CR), psychological resilience (PR), and deliberate rumination (DR),which are essential for understanding how and to what extent these factors shaped PTG in the context of the present pandemic. 463Chinese college students recruited via a convenience sampling method completed a set of online self-report measures of PC, PTG,CR, PR and DR. The findings revealed that the abovementioned five variables were positively correlated with each other, and theindependent variable directly predicted the dependent variable. More importantly, two out of three mediators in parallel mediatedthe relationship between PC and PTG, illustrating that more PC adoption was associated with increased PTG through high levels ofPR and DR, respectively. The two significant serial mediating effects also indicated that PC could contribute to CR, which furtherfacilitates either PR or DR and subsequently promotes the development of PTG. Colleges should adopt routine protectivebehaviors in accordance with such evidence to strengthen students’ mental health education and establish scientific methods toboost their psychological well-being. Overall, our results may shed new light on the process of positive adaption and providetheoretical support for targeted crisis intervention during the late phase of the pandemic. 展开更多
