Mental health surveillance in elite Para athletes: early identification and follow-up of athletes at risk of mental health problems.

OBJECTIVE: There is a lack of prospective data on mental health of elite Para athletes. The objective was to identify and follow elite Para athletes at risk of mental health problems. METHODS: In a 124-week prospective cohort study, mental health of German elite Para athletes was monitored using the Patient Health Questionnaire-4 (PHQ-4). In case of positive screening (PHQ-4≥5) over 2 weeks, a follow-up contact was conducted by a sports psychiatrist, who asked the athletes about their mental condition and sources for their mental distress and offered support. RESULTS: 7543 PHQ-4 scores were obtained from 122 Para athletes with a mean weekly response rate of 84%. The PHQ-4 screening was considered positive for symptoms of depression or anxiety with a prevalence of 6.7%, affecting 48.4% (n=59) of all participants at some point during the study period. In 76.6% (n=49) of all follow-up contacts, athletes (n=34) reported at least one mental health problem, most frequently mental distress (n=31), followed by symptoms of depression (n=19) including acute suicidality (n=1). The most common mental stressors cited were related to education and problems with the team, coaches or federation. At follow-up, almost two-thirds of the athletes were either already in professional psychiatric or psychological care (25%) or were recommended to seek such care (32.8%). CONCLUSION: Our screening and follow-up system revealed high rates of mental health problems in elite Para athletes. Programmes for early identification with mental health monitoring under the supervision of mental health professionals should be considered by sports federations for Para athletes.

Prevalence of DSM-5 somatic symptom disorder in Chinese patients with breast cancer.

OBJECTIVE: The aims of this study were to explore the frequency of somatic symptom disorder (SSD) and the relationship between SSD and somatic, psychological, and social factors in Chinese patients with breast cancer. METHODS: This multicenter cross-sectional study enrolled 264 patients with breast cancer from three different departments in Beijing. The structured clinical interview for fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (SCID-5) for SSD. Standardized questionnaires and clinical data were used to compare patients with and without SSD. RESULTS: Somatic symptom disorder was diagnosed in 21.6% (57/264) of all enrolled patients. No differences were found between SSD patients and non-SSD patients in terms of sociodemographic characteristics and tumor-specific variables, except radiotherapy. However, patients with SSD reported higher levels of depression, anxiety and cancer-related worry. They also showed a longer duration of symptoms, greater impairment in daily life, more concern over their physical complaints and more doctor visits. In a stepwise binary logistic regression analysis, among others, higher health anxiety (WI-8, Exp(B) = 0.107, p = 0.009) and more doctor visits (OR = -1.841, p < 0.001) showed a significant association with SSD; the model explained 53.7% of the variance. CONCLUSIONS: Similar to other physical diseases, there is a high prevalence of SSD in patients with breast cancer. Somatic symptom disorder patients differ from non-SSD patients by exhibiting higher cancer-related emotional distress and dysfunctional illness perception and behavior. There remain substantial challenges in the diagnosis of SSD in patients with cancer and other medical conditions. CLINICAL TRIAL REGISTRATION: ChiCTR2100051525.

A multicenter study of bodily distress syndrome in Chinese outpatient hospital care: prevalence and associations with psychosocial variables.

BACKGROUND: Bodily distress syndrome (BDS) is a new, empirical-based diagnosis of functional somatic symptoms. This study aimed to explore the prevalence of BDS and its association with psychosocial variables in a Chinese clinical population. METHODS: A multicentre cross-sectional study of 1269 patients was conducted in 9 different Chinese tertiary outpatient hospitals. The BDS was identified by trained interviewers face-to face, based on a brief version of the Schedules for Assessment in Neuropsychiatry (RIFD) and the BDS Checklist-25. Sociodemographic data and further information were characterised from psychometric questionnaires (The Patient Health Questionnaire-15, the Patient Health Questionnaire-9, the General Anxiety Disorder-7, the Whiteley scale-8) . RESULTS: Complete data were available for 697 patients. The prevalence of BDS was 26.8% (95% confidence interval (CI): 23.5-30.1). Among the participants, 5.8% (95% CI: 4.1-7.6) fulfilled the criteria for single-organ BDS, while 20.9% (95%CI: 17.9-24.0) had multi-organ BDS. Comparison of the PHQ-15, PHQ-9, GAD-7, and WI-8 scores revealed higher scores on all dimensions for patients with BDS. In a binary logistic regression analysis, BDS was significantly associated with increased health-related anxiety (WI-8) and depression (PHQ-9). The explained variance was Nagelkerke's R2 = 0.42. CONCLUSIONS: In China, the BDS is a common clinical condition in tertiary outpatient hospital settings with high prevalence, and is associated with health anxiety and depressive symptoms. In this clinical population, the severe multi-organ subtype of BDS was the most frequent.

The psychological impact of COVID-19 on Chinese healthcare workers: a systematic review and meta-analysis.

PURPOSE: This study aimed at investigating five dimensions of the psychological impact (post-traumatic stress symptoms (PTSS), anxiety, depression, sleep disturbance or profession-related burnout) of COVID-19 on healthcare workers (HCW) in China. METHODS: Studies that evaluated at least one of the five target dimensions of the psychological impact of COVID-19 on HCW in China were included. Studies with no data of our interest were excluded. Relevant Databases were searched from inception up to June 10, 2020. Preprint articles were also included. The methodological quality was assessed using the checklist recommended by AHRQ. Both the rate of prevalence and the severity of symptoms were pooled. The protocol was registered in PROSPERO (CRD42020197126) on July 09, 2020. RESULTS: We included 44 studies with a total of 65,706 HCW participants. Pooled prevalence rates of moderate to severe PTSS, anxiety, depression, and sleep disturbances were 27% (95% CI 16%-38%), 17% (13-21%), 15% (13-16%), and 15% (7-23%), respectively; while the prevalence of mild to severe level of PTSS, anxiety, and depression was estimated as 31% (25-37%), 37% (32-42%) and 39% (25-52%). Due to the lack of data, no analysis of profession-related burnout was pooled. Subgroup analyses indicated higher prevalence of moderate to severe psychological impact in frontline HCW, female HCW, nurses, and HCW in Wuhan. CONCLUSION: About a third of HCW in China showed at least one dimension of psychological symptoms during the COVID-19 pandemic, whereas the prevalence of moderate and severe syndromes was relatively low. Studies on profession-related burnout, long-term impact, and the post-stress growth are still needed.

Mental Health Screening of Syrian Refugees in Germany: The Refugee Health Screener Objectives: The purpose of the present study was to examine (1) the impact of training in psychotherapy on professional activities and personal life and (2) the frequency of psychotherapy services in primary care and specialty practices. Method: General practitioners and specialists in outpatient medical practices from Baden-Württemberg (n = 289) with completed additional training in psychotherapy were asked to fill out a questionnaire about the current state of implementation in their medical practice. Data were analyzed using descriptive and correlative statistical methods. Results: The response rate was 53.7 % (n = 150). Physicians reported very positive effects on professional activity, job and life satisfaction, and personal growth. They provide an average of 9.1 hours (SD 6.4) of psychotherapy per week. They provide low-frequency psychotherapy for longer periods per quarter to 21.3 (SD 55.6) patients with primarily chronic physical illnesses. Conclusions: Additional training in psychotherapy for physicians seems to be proving successful in its implementation in medical practice. Most physicians regularly provide psychotherapy on a small but significant scale. Further cross-regional studies including data from health insurance companies are needed.

Severe sleep disturbance is associated with executive function impairment in patients with first-episode, treatment-naïve major depressive disorders.

BACKGROUND: Sleep disturbance and executive function impairment are common in patients with major depressive disorder (MDD), though the relationship between the two remains unclear. We investigated this association in first-episode, treatment-naïve patients with MDD. METHODS: We analyzed data from 242 patients with MDD. We divided the patients into 2 groups based on sleep disturbance severity and compared the executive function odds ratios between the groups. RESULTS: A total of 121 pairs of patients were matched (age 39.4 ± 10.1, 70.2% female). After propensity score matching, the odds ratios for cognitive impairment in patients with MDD and severe sleep disturbance were 1.922 (1.068-3.459, P = 0.029, q = 0.044) in executive functioning; 2.023 (1.211-3.379, P = 0.007, q = 0.021) in executive shifting. CONCLUSIONS: Sleep disturbance is associated with executive functioning impairment in first-episode, treatment-naïve patients with MDD. Severe sleep disturbance can be a marker and aid in recognizing executive function impairment in patients with first-episode treatment-naïve MDD. Severe sleep disturbance can be a potential modifiable factor to improve executive function in MDD, as well as an effective measurement to improve cognition for sleep symptom management that should be enforced at initial treatment of first-episode MDD. Further study is required to confirm our results. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02023567 ; registration date: December 2013.

Assessment of the structured clinical interview (SCID) for DSM-5 for somatic symptom disorder in general hospital outpatient clinics in China.

BACKGROUND: It is still unknown whether the "Somatic symptom disorders (SSD) and related disorders" module of the Structured Clinical Interview for DSM-5, research version (SCID-5-RV), is valid in China. This study aimed to assess the SCID-5-RV for SSD in general hospital outpatient clinics in China. METHODS: This multicentre cross-sectional study was conducted in the outpatient clinics of nine tertiary hospitals in Beijing, Jincheng, Shanghai, Wuhan, and Chengdu between May 2016 and March 2017. The "SSD and related disorders" module of the SCID-5-RV was translated, reversed-translated, revised, and used by trained clinical researchers to make a diagnosis of SSD. Several standardized questionnaires measuring somatic symptom severity, emotional distress, and quality of life were compared with the SCID-5-RV. RESULTS: A total of 699 patients were recruited, and 236 were diagnosed with SSD. Of these patients, 46 had mild SSD, 78 had moderate SSD, 100 had severe SSD, and 12 were excluded due to incomplete data. The SCID-5-RV for SSD was highly correlated with somatic symptom severity, emotional distress, and quality of life (all P < 0.001) and could distinguish nonsevere forms of SSD from severe ones. CONCLUSIONS: This study suggests that SCID-5-RV for SSD can distinguish SSD from non-SSD patients and severe cases from nonsevere cases. It has good discriminative validity and reflects the DSM-5 diagnostic approach that emphasizes excessive emotional, thinking, and behavioural responses related to symptoms.

How can learning effects be measured in Balint groups? Validation of a Balint group questionnaire in China.

BACKGROUND: Balint groups aim to reflect doctor-patient relationships on the basis of personal cases. This study reports the validation of a questionnaire aimed at the identification of learning processes among Balint group participants in China. METHODS: This multicenter cross-sectional study was conducted during Balint group sessions in Beijing, Guangzhou and Shanghai. A heterogeneous sample of different professional groups was intended to adequately capture the reality of Balint work in China. After a Balint group session, the participants were asked to complete the Mandarin version of the Balint group session questionnaire (BGQ-C) and the group questionnaire (GQ), an internationally validated instrument to assess central dimensions of therapeutic relationships during group processes. RESULTS: Questionnaires from n = 806 participants from 55 Chinese Balint groups, predominantly comprising individuals with a medical background, were analyzed. Most participants were female (74.6%), and the average age was 34.2 years old (SD = 9.4). The results indicated good to very good reliability (Cronbach's α = .70 to .86; retest rs = .430 to .697). The verification of the construct validity of the BGQ-C showed satisfying convergent (rs = .465 to .574) and discriminant validity (rs = -.117 to -.209). The model was tested with a confirmatory factor analysis of a three-factor model (standardized root mean square residual = .025; comparative fit index = .977; Tucker-Lewis index = .971). The 3 empirically identified scales resulted in good model fit with the theoretical dimensions of Balint work postulated in the literature: "reflection of transference dynamics in the doctor-patient relationship", "emotional and cognitive learning" and "case mirroring in the dynamic of the group". Due to the high correlations between the factors, a single-factor model was possible. A group comparison between the German and Chinese samples showed different loadings across cultures. CONCLUSIONS: The BGQ-C is a quick-to-complete, item-based measuring instrument that allows the relevant dimensions of Balint group work to be recorded. This study suggests good psychometric properties of the Chinese version. Nevertheless, it must be assumed that the composition of constructs in the two countries is different.

[Balint group as a mandatory training - Effects of Balint work as part of the psychosomatic basic care course]. / Balintgruppe als Pflichtveranstaltung ­ Effekte von Balintarbeit im Rahmen des Kurses Psychosomatische Grundversorgung.

Balint group as a mandatory training - Effects of Balint work as part of the psychosomatic basic care course Objectives: Participants in the psychosomatic basic care course often lack a genuine interest in Balint work. What effects does Balint work have on these inexperienced and less motivated participants? Are there differences between male and female participants and between surgical and non-surgical specialties? What are the relationships between the group leaders and the results achieved? Methods: Between 2004 and 2019, a total of 1,667 doctors completed the feedback form for the Balint group as part of the psychosomatic basic care course. The learning objectives included cognitive and emotional items, as well as questions about the group atmosphere and leadership, about the transfer to everyday medical practice and interest in further Balint work. Results: 170 Balint groups took place during the investigation period. The overall grade was on a scale from 1 to 6 with M = 1.80 (SD = 0.72). Good to very good ratings were awarded to the motivation and competence of the group leaders and the group atmosphere, as well as gaining knowledge and positive effects on everyday medical practice. There were hardly any differences between female and male participants and between surgical and non-surgical participants. However, there were significant correlations between the assessment of the leader and the effects of group work. Discussion: The predominantly positive assessment of Balint's work is surprising, both in terms of cognitive and emotional learning goals. In addition to the group atmosphere, the motivation and competence of the group leader, perceived by the participants, are closely related to the learning effects achieved. The survey shows that Balint work can achieve positive results even with less motivated participants on a compulsory course. Balint work should therefore remain an integral part of the qualification in psychosomatic basic care. Sound training and supervision of Balint group leaders are necessary.

Validation of the Chinese Version of the Somatic Symptom Disorder-B Criteria Scale for Detecting DSM-5 Somatic Symptom Disorders: A Multicenter Study.

OBJECTIVE: This study aimed to validate the Chinese version of the Somatic Symptom Disorder-B Criteria Scale (SSD-12) in an outpatient sample from Chinese general hospitals and to determine the diagnostic performance of the SSD-12 as a screening tool for somatic symptom disorder (SSD). METHODS: The Chinese version of the SSD-12 was completed by 699 outpatients from nine general hospitals during a 16-month period (2016-2018). The SSD section of the Structured Clinical Interview for DSM Disorders, Fifth Edition, Research Version, was used to determine diagnostic accuracy (criterion validity). The construct validity of the SSD-12 was evaluated by examining correlations with the Whiteley Index-7, Patient Health Questionnaire-15, Patient Health Questionnaire-9, General Anxiety Disorder-7, World Health Organization Disability Assessment Schedule, and Medical Outcome Study 12-item Short Form Health Survey (SF-12). RESULTS: The SSD-12 had excellent internal consistency in this sample (Cronbach α = .95). Confirmatory factor analyses replicated a three-factor structure that reflects the cognitive, affective, and behavioral aspects (Comparative Fit Index = 0.963, Tucker-Lewis Index = 0.952, root mean square error of approximation = 0.08, 90% confidence interval = 0.08-0.09), but was also consistent with a general one-factor model of the SSD-12 (Comparative Fit Index = 0.957, Tucker-Lewis Index = 0.948, root mean square error of approximation = 0.09, 90% confidence interval = 0.08-0.10). The optimal cutoff point for the Structured Clinical Interview for DSM Disorders-based diagnosis of SSD was 16 (sensitivity = 0.76, specificity = 0.80). The SSD-12 sum score was significantly associated with somatic symptom burden (Patient Health Questionnaire-15: r = 0.52, p < .001), health anxiety (Whiteley Index-7: r = 0.82, p < .001), depressive symptoms (Patient Health Questionnaire-9: r = 0.63, p < .001), general anxiety (General Anxiety Disorder-7: r = 0.64, p < .001), health-related quality of life (physical component score of SF-12: r = -0.49, p < .001; mental component score of SF-12: r = -0.61, p < .001), and health-related disabilities (World Health Organization Disability Assessment Schedule: r = 0.56, p < .001). CONCLUSIONS: Initial assessment indicates that the Chinese version of the SSD-12 has sufficient reliability and validity to warrant further testing in both research and clinical settings.

Physical and psychological correlates of high somatic symptom severity in Chinese breast cancer patients.

OBJECTIVE: We researched associations between somatic symptom severity (SSS), and physical and psychological factors in Chinese breast cancer patients. METHODS: This multicenter cross-sectional study enrolled 255 Chinese breast cancer patients of different stages and treatment phases. They answered standard instruments assessing SSS (Patient Health Questionnaire [PHQ]-15), depression (PHQ-9), anxiety (General Anxiety Disorder [GAD]-7), health anxiety (Whiteley-7 [WI-7]), illness perception (Brief-Illness Perception Questionnaire [IPQ]), illness attribution (Illness Perception Questionnaire-Revised [IPQ-R]), and sense of coherence (Sense of Coherence [SOC]-9). Logistic regression was applied to identify the strongest correlates with SSS. RESULTS: Our sample of high (PHQ-15 ≥ 10) and low SSS differed significantly in the following physical and psychological variables: symptom duration (r = 0.339, P < .001), symptom-related disability (Karnofsky Index) (r = 0.182, P < .001), depression (r = 0.556, P < .001), anxiety (r = 0.433, P < .001), health anxiety (r = 0.400, P < .001), illness perception (r = 0.349, P < .001), psychological illness attributions (r = 0.217, P < .01), and sense of coherence (r = -0.254, P < .001). In an adjusted stepwise multiple binary logistic regression analysis, higher health anxiety (WI-7, B = 0.388, P = .002), higher depression (PHQ-9, B = 0.158, P < .001), younger age (B = -0.042, P = .048), higher impairment in daily life (B = 1.098, P = .010), and longer symptom duration (Wald = 18.487, P = .001) showed a significant association with high SSS; the model explained 55.1% of the variance. CONCLUSIONS: High somatic symptom burden in breast cancer is associated with physical and psychosocial features. The results are a basis for further research to evaluate the new Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, SSD concept in cancer patients and to better operationalize psychobehavioral factors in this patient group.

Emotional distress and dysfunctional illness perception are associated with low mental and physical quality of life in Chinese breast cancer patients.

BACKGROUND: To evaluate the relationship between quality of life (QOL) and physical as well as psychological variables in Chinese breast cancer patients. METHODS: This multicenter cross-sectional study enrolled 254 Chinese breast cancer patients in different stages and treatment phases. They answered standard instruments assessing QOL (EORTC), somatic symptom severity (PHQ-15), depression (PHQ-9), anxiety (GAD-7), health-related anxiety (WI-7), illness perception (BIPQ), and sense of coherence (SOC-9). Canonical correlation was applied to identify the strongest correlates between the physical, emotional and social QOL scales and the physical and psychological variables. RESULTS: In our sample, a low global QOL was significantly associated with the following physical and psychological variables: symptom-related disability (Karnofsky Index) (r = .211, p < .01), somatic symptom severity (r = -.391, p < .001), depression (r = -.488, p < .001), anxiety (r = -.439, p < .001), health-related anxiety (r = -.398, p < .001), dysfunctional illness perception (r = -.411, p < .001), and sense of coherence (r = .371, p < .001). In the canonical correlation analysis, high somatic symptom severity, depression, anxiety, dysfunctional illness perception, and low sense of coherence showed the strongest correlations with low physical, emotional and social functioning. The first three significant canonical correlations between these two sets of variables were .78, .56, and .45. CONCLUSIONS: QOL in Chinese breast cancer patients is strongly associated with psychological factors. Our results suggest that Chinese physicians and nurses should incorporate these factors into their care for women with breast cancer to improve patients' QOL.

Operationalization of diagnostic criteria of DSM-5 somatic symptom disorders.

BACKGROUND: The aim of this study was to test the operationalization of DSM-5 somatic symptom disorder (SSD) psychological criteria among Chinese general hospital outpatients. METHODS: This multicenter, cross-sectional study enrolled 491 patients from 10 general hospital outpatient departments. The structured clinical "interview about cognitive, affective, and behavioral features associated with somatic complaints" was used to operationalize the SSD criteria B. For comparison, DSM-IV somatoform disorders were assessed with the Mini International Neuropsychiatric Interview plus. Cohen's к scores were given to illustrate the agreement of the diagnoses. RESULTS: A three-structure model of the interview, within which items were classified as respectively assessing the cognitive (B1), affective (B2), and behavioral (B3) features, was examined. According to percentages of screening-positive persons and the receiver operator characteristic (ROC) analysis, a cut-off point of 2 was recommended for each subscale of the interview. With the operationalization, the frequency of DSM-5 SSD was estimated as 36.5% in our sample, and that of DSM-IV somatoform disorders was 8.2%. The agreement between them was small (Cohen's к = 0.152). Comparisons of sociodemographic features of SSD patients with different severity levels (mild, moderate, severe) showed that mild SSD patients were better-off in terms of financial and employment status, and that the severity subtypes were congruent with the level of depression, anxiety, quality of life impairment, and the frequency of doctor visits. CONCLUSIONS: The operationalization of the diagnosis and severity specifications of SSD was valid, but the diagnostic agreement between DSM-5 SSD and DSM-IV somatoform disorders was small. The interpretation the SSD criteria should be made cautiously, so that the diagnosis would not became over-inclusive.

Effect of a Website That Presents Patients' Experiences on Self-Efficacy and Patient Competence of Colorectal Cancer Patients: Web-Based Randomized Controlled Trial.

BACKGROUND: Patients often seek other patients' experiences with the disease. The Internet provides a wide range of opportunities to share and learn about other people's health and illness experiences via blogs or patient-initiated online discussion groups. There also exists a range of medical information devices that include experiential patient information. However, there are serious concerns about the use of such experiential information because narratives of others may be powerful and pervasive tools that may hinder informed decision making. The international research network DIPEx (Database of Individual Patients' Experiences) aims to provide scientifically based online information on people's experiences with health and illness to fulfill patients' needs for experiential information, while ensuring that the presented information includes a wide variety of possible experiences. OBJECTIVE: The aim is to evaluate the colorectal cancer module of the German DIPEx website krankheitserfahrungen.de with regard to self-efficacy for coping with cancer and patient competence. METHODS: In 2015, a Web-based randomized controlled trial was conducted using a two-group between-subjects design and repeated measures. The study sample consisted of individuals who had been diagnosed with colorectal cancer within the past 3 years or who had metastasis or recurrent disease. Outcome measures included self-efficacy for coping with cancer and patient competence. Participants were randomly assigned to either an intervention group that had immediate access to the colorectal cancer module for 2 weeks or to a waiting list control group. Outcome criteria were measured at baseline before randomization and at 2 weeks and 6 weeks. RESULTS: The study randomized 212 persons. On average, participants were 54 (SD 11.1) years old, 58.8% (124/211) were female, and 73.6% (156/212) had read or heard stories of other patients online before entering the study, thus excluding any influence of the colorectal cancer module on krankheitserfahrungen.de. No intervention effects were found at 2 and 6 weeks after baseline. CONCLUSIONS: The results of this study do not support the hypothesis that the website studied may increase self-efficacy for coping with cancer or patient competencies such as self-regulation or managing emotional distress. Possible explanations may involve characteristics of the website itself, its use by participants, or methodological reasons. Future studies aimed at evaluating potential effects of websites providing patient experiences on the basis of methodological principles such as those of DIPEx might profit from extending the range of outcome measures, from including additional measures of website usage behavior and users' motivation, and from expanding concepts, such as patient competency to include items that more directly reflect patients' perceived effects of using such a website.

Psychological and somatic distress in Chinese outpatients at general hospitals: a cross-sectional study.

BACKGROUND: Our study aimed (1) to describe the proportion of psychological distress among Chinese outpatients at general hospitals, (2) to compare cognitive and behavioral characteristics of patients with different distress patterns, and (3) to investigate the discriminant function of the analyzed variables in indicating the affinity towards the different distress patterns. METHODS: This multicenter cross-sectional study was conducted at ten outpatient departments at Chinese general hospitals. The somatic symptom severity scale (PHQ-15), the nine-item depression scale (PHQ-9), and the seven-item anxiety scale (GAD-7) were employed to classify patients in terms of four distress patterns. RESULTS: A total of 491 patients were enrolled. Among them, the proportion of patients with high psychological distress was significantly higher within those with high somatic distress (74.5% vs. 25.5%, p < .001). Patients with psychological distress alone and mixed distress were significantly younger and with lower monthly family income, while the proportion of female patients (80.9%) was highest in the somatic distress group. Patients with mixed distress had the most negative cognitive and behavioral characteristics [highest health anxiety (5.0 ± 1.9), lowest sense of coherence (35.5 ± 10.0), the worst doctor-patient relationship from both patients' (36.0 ± 7.3) and doctors' perspectives (23.3 ± 7.0)], as well as most impaired quality of life (41.6 ± 7.4 and 31.9 ± 10.3). In addition, compared with patients with somatic distress alone, those with psychological distress alone had lower sense of coherence, worse doctor-patient relationship, and more impaired mental quality of life, but less doctor visits. Discriminant analysis showed that gender, mental quality of life, health anxiety, sense of coherence, and frequent doctor visits were significant indicators in identifying patients with different distress patterns. CONCLUSIONS: Our study found that (1) psychological distress was not rare in the Chinese general hospital outpatients, especially in those with high somatic distress; (2) patients with psychological distress alone sought less help from doctors, despite their severe psychosocial impairment; and (3) gender, health anxiety, sense of coherence, mental quality of life, and frequent doctor visits could help to identify different distress patterns.

Validation of the Chinese version of the PHQ-15 in a tertiary hospital.

BACKGROUND: This study aimed to investigate the reliability and validity of the Chinese version of the Patient Health Questionnaire (PHQ-15) in a tertiary hospital. METHODS: Using a cross-sectional study design, the Chinese version of the PHQ-15 was administered to a total of 1329 inpatients. To examine the discriminant validity of this questionnaire, we investigated the correlation of the PHQ-15 score with sociodemographic data and the PHQ-9 and GAD-7 scale scores. Exploratory factor analysis was performed to assess the internal consistency of the PHQ-15. To evaluate the consistency of this questionnaire with item response theory (IRT), IRT analysis was performed. RESULTS: The Chinese version of the PHQ-15 showed good reliability (Cronbach's alpha = 0.83). The correlations of the PHQ-15 scores with the PHQ-9 depression scale scores (r = 0.565) and the GAD-7 anxiety scale scores (r = 0.512) were moderate; these results suggested that the PHQ-15 had discriminant validity. We identified three factors, referred to as "cardiopulmonary," "gastrointestinal," and "pain/neurological," which explained 56 % of the total variance. A second-order factor analysis including these three factors produced an acceptable model. Several items (4, 8 and 11) displayed extreme floor effects. Additionally, item 4 displayed a very small variance of 0.35 and showed very small differences in its thresholds based on IRT analysis. CONCLUSIONS: The PHQ-15 scale had good reliability and high validity to detect patients with high somatic symptom severity in a Chinese tertiary hospital. Several of the current findings were consistent with previous research on the PHQ-15 in Western countries and in China. To improve the diagnostic quality of this questionnaire, items 4, 8 and 11 can be omitted.

Short-term intervention to reduce anxiety before coronary artery bypass surgery--a randomised controlled trial.

AIMS AND OBJECTIVES: The aim of this study was to evaluate an intervention with individualised information and emotional support before coronary artery bypass grafting in a controlled randomised trial. BACKGROUND: Anxiety is a typical phenomenon in patients who are to undergo cardiac surgery. Preoperative anxiety has been shown to correlate to adverse postoperative outcomes. Emotional support could be an effective measure to reduce preoperative anxiety. DESIGN AND METHODS: Patients with planned first coronary artery bypass grafting were randomised into an intervention group (n = 139) and a control group (n = 114). The patients of the control group were routinely informed as usual. The patients of the intervention group received a dialogue with individualised information and emotional support one day before surgery in addition to standard care. This intervention of ~30 minutes was based on a supportive psychotherapy model and was delivered by trained nurses. The primary outcome was the change in anxiety before operation. The secondary outcomes consisted of changes in postoperative anxiety, time on intensive care unit and in-hospital mortality. RESULTS: Significantly reduced anxiety was found in the intervention group patients compared to control patients before coronary artery bypass grafting (p < 0·001) and five days after surgery (p < 0·001). Both groups did not differ in in-hospital mortality and duration of stay in the intensive care unit. CONCLUSIONS: Our short-term psychosocial intervention in patients undergoing coronary artery bypass grafting had a beneficial effect on reducing pre- and postoperative anxiety that was better than routine information alone. RELEVANCE TO CLINICAL PRACTICE: These results advocate training for nurses and physicians to provide emotional support to patients before coronary artery bypass grafting.

Sense of coherence contributes to physical and mental health in general hospital patients in China.

The sense of coherence (SOC) may explain why some people become ill under stress whereas others remain healthy. SOC is strongly related to perceived health, particularly mental health. Little is known about the physical and mental health statuses associated with SOC among general hospital outpatients in China. This multicentre cross-sectional study analysed 491 outpatients from four large Chinese general hospitals located in Beijing, Shanghai, Chengdu and Kunming. Patients completed questionnaires examining their SOC (SOC-9), somatic symptom severity (PHQ-15), depression (PHQ-9), generalised anxiety disorder (GAD), health anxiety (WI-7), quality of life (QoL; SF-12) and socio-demographic and clinical characteristics. SOC was negatively correlated with daily-life impairment, symptom duration, somatic symptom severity, depression, GAD and health anxiety, but was positively correlated with age as well as physical and mental QoL. Using a multiple linear regression model, the three strongest correlates of SOC were mental QoL, depression and age. These three variables explained 52% of the variance. SOC may be an important contributor to both mental and physical health in Chinese general hospital outpatients, which is consistent with the results obtained for primary care patients in Western countries. Longitudinal studies are needed to investigate how SOC predicts physical and mental health statuses over time and how these statuses respond to treatment for low SOC.

Negative illness perceptions associated with low mental and physical health status in general hospital outpatients in China.

In western countries, negative illness perceptions are associated with poor health status and affect health outcomes in primary care populations. The aim of this study is to examine the relationship between illness perception and mental and physical health status in general hospital outpatients in China. This multicentre, cross-sectional study analysed a total of 281 consecutive patients from four general hospital outpatient departments of internal medicine and traditional Chinese medicine in Beijing and Kunming. The patients answered questionnaires concerning illness perception (Brief-IPQ), somatic symptom severity (Patient Health Questionnaire-15), illness behaviour (Scale for the Assessment of Illness Behaviour), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (Twelve-Item Short Form Health Survey). Negative illness perception, especially negative emotional reactions, perceived illness consequences, encumbering illness concerns, and strong illness identity were significantly associated with high emotional distress, impairing illness consequences, and a low mental and physical quality of life. Using a multiple linear regression model, five strongest correlates of negative illness perception were high anxiety, seeking diagnosis verification, low mental and physical quality of life and high somatic symptom severity. The variance explained by this model was 35%. Chinese general hospital outpatients showed associations between negative illness perceptions and poor mental and physical health status that were similar to those of primary care patients in western countries. The main difference was that no association with perceived illness control was found in Chinese patients. Chinese physicians should be sensitised to their patients' negative illness perceptions and should focus on helping patients cope with uncertainty and anxiety by providing an understandable illness model and increasing control beliefs.
