RESUMEN
BACKGROUND: The incidence of stroke is a challenge in China, as stroke imposes a heavy burden on families, national health services, social services, and the economy. The length of hospital stay (LOS) is an essential indicator of utilization of medical services and is usually used to assess the efficiency of hospital management and patient quality of care. This study established a prediction model based on a machine learning algorithm to predict ischemic stroke patients' LOS. METHODS: A total of 18,195 ischemic stroke patients' electronic medical records and 28 attributes were extracted from electronic medical records in a large comprehensive hospital in China. The prediction of LOS was regarded as a multi classification problem, and LOS was divided into three categories: 1-7 days, 8-14 days and more than 14 days. After preprocessing the data and feature selection, the XGBoost algorithm was used to build a machine learning model. Ten fold cross-validation was used for model validation. The accuracy (ACC), recall rate (RE) and F1 measure were used to evaluate the performance of the prediction model of LOS of ischemic stroke patients. Finally, the XGBoost algorithm was used to identify and remove irrelevant features by ranking all attributes based on feature importance. RESULTS: Compared with the naive Bayesian algorithm, logistic region algorithm, decision tree classifier algorithm and ADaBoost classifier algorithm, the XGBoot algorithm has higher ACC, RE and F1 measure. The average ACC, RE and F1 measure were 0.89, 0.89 and 0.89 under the 10-fold cross-validation. According to the analysis of the importance of features, the LOS of ischemic stroke patients was affected by demographic characteristics, past medical history, admission examination features, and operation characteristics. Finally, the features in terms of hemiplegia aphasia, MRS, NIHSS, TIA, Operation or not, coma index etc. were found to be the top features in importance in predicting the LOS of ischemic stroke patients. CONCLUSIONS: The XGBoost algorithm was an appropriate machine learning method for predicting the LOS of patients with ischemic stroke. Based on the prediction model, an intelligent medical management prediction system could be developed to predict the LOS based on ischemic stroke patients' electronic medical records.

This data article presents data from the China Migrants Dynamic Survey (CMDS), a multi-wave, large-scale national cross-sectional survey of China's internal migrants from 2009 to 2018. The CMDS is an annual questionnaire survey conducted by the former National Health and Family Planning Commission (NHFPC) of the People's Republic of China. The respondents included in this survey are internal migrants over 15 years old. The sample was drawn from the China Migrant Population Information System, using multi-stage stratified sampling method and the probability proportional-to-size (PPS) cluster sampling strategy. Between 2009 and 2018, there were 1,527,650 internal migrants from 23 provinces, 5 autonomous regions and 4 municipalities participated in the surveys. The survey tools were a series of self-designed questionnaires with high inheritance and consistency designed and implemented by the NHFPC. The questionnaires mainly contain basic information of the respondents and their family members, migration status, healthcare or health behaviors, public health service utilization, social insurance, social integration, and family planning. The dataset is currently the most widely used survey data on China's internal migrants, offering information on migration patterns, healthcare and health behaviors, use of public health services, access to social security, social integration, and family planning, which are valuable for health planning, health decision-making, and health equity research.

BACKGROUND: Several studies have demonstrated that smoke-free legislation is associated with a reduced risk of mortality from acute myocardial infarction (AMI). This study aimed to examine and quantify the potential effect of smoke-free legislation on AMI mortality rate in different countries. METHODS: Studies were identified using a systematic search of the scientific literature from electronic databases, including PubMed, Web of Science, ScienceDirect, Embase, Google Scholar, and China National Knowledge Infrastructure (CNKI), from their inception through September 30, 2017. A random effects model was employed to estimate the overall effects of smoke-free legislation on the AMI mortality rate. Subgroup analysis was performed to explore the possible causes of heterogeneity in risk estimates based on sex and age. The results of meta-analysis after excluding the studies with a high risk of bias were reported in this study. RESULTS: A total of 10 eligible studies with 16 estimates of effect size were included in this meta-analysis. Significant heterogeneity in the risk estimates was identified (overall I2 = 94.6%, p < 0.001). Therefore, a random effects model was utilized to estimate the overall effect of smoke-free legislation. There was an 8% decline in AMI mortality after introducing smoke-free legislation (RR = 0.92, 95% confidence interval (CI): 0.90-0.94). The results of subgroup analyses showed that smoke-free legislation was significantly associated with lower rates of mortality for the following 5 diagnostic subgroups: smoke-free in workplaces, restaurants and bars (RR = 0.92, 95% CI: 0.90-0.95), smaller sample size (RR = 0.92, 95% CI: 0.89-0.95), study location in Europe (RR = 0.90, 95% CI: 0.85-0.94), regional study area (RR = 0.92, 95% CI: 0.89-0.94), and no previous local smoke-free legislation (RR = 0.91, 95% CI: 0.90-0.93). However, there was not much difference in AMI mortality rates after the legislation between the longer (RR = 0.92, 95% CI: 0.86-0.98) and shorter follow-up duration subgroups (RR = 0.92, 95% CI: 0.89-0.94). CONCLUSION: Smoke-free legislation could significantly reduce the AMI mortality rate by 8%. The reduction in the AMI mortality rate was more significant in studies with more comprehensive laws, without prior smoke-free bans, with a smaller sample size, at the regional level, and with a location in Europe.

BACKGROUND: Trust is regarded as the cornerstone of the doctor-patient relationship in the world of medicine; it determines the decisions patients make when choosing doctors and influences patients' compliance with recommended treatments. In China, patient-doctor trust acts as a thermometer measuring harmony in the doctor-patient relationship. The objective of this study is to explore the relationship between the contract service and patient-doctor trust-building in 25 village clinics of rural China. METHOD: The research was carried out in village clinics in rural China. A simple random sampling method was used to choose clinics and subjects. Based on feasibility and financial support, we chose three counties as our study settings: Dafeng District, Jiangsu Province; Yinan County, Shandong Province; and Wufeng Tujia Autonomous County, Hubei Province. Twenty-five village clinics and 574 subjects were selected in the three areas from the contract service and patient list. Descriptive statistics, t-tests, MANOVA, SEM, and multiple regression statistical analysis were employed to analyze the data. RESULT: Statistical analysis showed that contract service directly and indirectly influenced patient-doctor trust-building in village clinics. The patient perception of doctor communication skills was a mediator in the relationship between contract service policy and patient-doctor trust-building. CONCLUSIONS: Building patient-doctor trust is important in developing and enhancing rural health. The policy of contract service plays a significant role in building relationships. Well-developed communication skills of doctors contribute to the implementation of the contract service policy and to establishing patient-doctor trust.

BACKGROUND: Existing studies in developed countries show that social participation has beneficial effects on the functional ability of older adults, but research on Chinese older people is limited. This study examined the effects of participating in different types of social activities on the onset of functional disability and the underlying behavioral and psychosocial mechanisms among older adults aged 65 and older in China. METHODS: The 2005, 2008, and 2011 waves of the Chinese Longitudinal Health Longevity Study were used. Life table analysis and discrete time hazard models were adopted to examine the relationship between social participation and functional disability. Social participation was defined as the frequencies of engaging in group leisure-time activities (i.e., playing cards/mahjong) and organized social activities, involving in informal social interactions (i.e., number of siblings frequently visited), and participating in paid jobs. Extensive social participation was measured by a composite index by adding up the four types of social activities that an older person was engaged in. RESULTS: After controlling for the effect of socio-demographic characteristics, health status, and health behavioral factors, extensive social participation is associated with a significant reduced risk for the onset of functional disability (hazard ratio [HR] = 0.92, p < 0.001). Different types of social participation affect the risk of functional decline through different mechanisms. Frequent playing of cards/mahjong is a protective factor for functional decline (HR = 0.78, p < 0.001), and the relationship is partially mediated by cognitive ability and positive emotions (accounting for 18.9% and 7.0% of the association, respectively). Frequent participation in organized social activities is significantly related to a reduced risk of functional decline (HR = 0.78, p < 0.001), and the association is mediated by physical exercises and cognitive ability (accounting for 25.7% and 17.7% of the association, respectively). Frequent visits from siblings has a strong inverse relationship with functional decline (HR = 0.75, p < 0.001). However, no significant association between paid job and functional decline is observed. CONCLUSION: Extensive social participation, regular engagement in group leisure-time activities, organized social activities, and informal social interactions in particular may have beneficial effects on the functional health of older adults through behavioral and psychosocial pathways. The findings shed light for the importance of promoting social participation among older adults.

BACKGROUND: In 2009, health-care reform was launched to achieve universal health coverage in China. A good understanding of how China's health reforms are influencing village doctors' income structure will assist authorities to adjust related polices and ensure that village doctors employment conditions enable them to remain motivated and productive. This study aimed to investigate the village doctors' income structure and analyse how these health policies influenced it. METHODS: Based on a review of the previous literature and qualitative study, village doctors' income structure was depicted and analysed. A qualitative study was conducted in six counties of six provinces in China from August 2013 to January 2014. Forty-nine village doctors participated in in-depth interviews designed to document their income structure and its influencing factors. The themes and subthemes of key factors influencing village doctors' income structure were analysed and determined by a thematic analysis approach and group discussion. RESULTS: Several policies launched during China's 2009 health-care reform had major impact on village doctors. The National Essential Medicines System cancelled drug mark-ups, removing their primary source of income. The government implemented a series of measures to compensate, including paying them to implement public health activities and provide services covered by social health insurance, but these have also changed the village doctors' role. Moreover, integrated management of village doctors' activities by township-level staff has reduced their independence, and different counties' economic status and health reform processes have also led to inconsistencies in village doctors' payment. These changes have dramatically reduced village doctors' income and employment satisfaction. CONCLUSIONS: The health-care reform policies have had lasting impacts on village doctors' income structure since the policies' implementation in 2009. The village doctors have to rely on the salaries and subsidies from the government after the drug mark-up was cancelled. China's national health reforms are attempting to draw village doctors into the national health workforce, but the policies have impacted their income and independence. Further research into these concerns and monitoring of measures to adequately compensate village doctors should be undertaken. Reasonable compensation strategies should be established, and sufficient subsidies should be allocated in a timely manner.

BACKGROUND: The Chinese government has increased the funding for public health in 2009 and experimentally applied a contract service policy (could be seen as a counterpart to family medicine) in 15 counties to promote public health services in the rural areas in 2013. The contract service aimed to convert village doctors, who had privately practiced for decades, into general practitioners under the government management, and better control the rampant chronic diseases. This study made a rare attempt to assess the effectiveness of public health services delivered under the contract service policy, explore the influencing mechanism and draw the implications for the policy extension in the future. METHODS: Three pilot counties and a non-pilot one with heterogeneity in economic and health development from east to west of China were selected by a purposive sampling method. The case study methods by document collection, non-participant observation and interviews (including key informant interview and focus group interview) with 84 health providers and 20 demanders in multiple level were applied in this study. A thematic approach was used to compare diverse outcomes and analyze mechanism in the complex adaptive systems framework. RESULTS: Without sufficient incentives, the public health services were not conducted effectively, regardless of the implementation of the contract policy. To appropriately increase the funding for public health by local finance and properly allocate subsidy to village doctors was one of the most effective approaches to stimulate health providers and demanders' positivity and promote the policy implementation. County health bureaus acted as the most crucial agents among the complex public health systems. Their mental models influenced by the compound and various environments around them led to the diverse outcomes. If they could provide extra incentives and make the contexts of the systems ripe enough for change, the health providers and demanders would be receptive to the transition of the policy. CONCLUSIONS: The innovative fund raising measures could be taken by relatively developed counties of China to conduct public health services. Policymakers could take systems thinking as a useful tool to design plans and predict the unintended outcomes during the process of public health reforms.

BACKGROUND: Suicide is an urgent public health challenge for China. This study aims to examine the prevalence, influence factors, and gender differences of suicidal ideation among general population in Northwestern Urban China. METHODS: Data used in this study were derived from the third wave of a cohort study of a randomized community sample with 4291 participants (≥ 20 years) in 2008 in Lanzhou City and Baiyin City, Gansu Province. Data were collected via face-to-face interview by the trained interviewers. Descriptive analyses, chi-square tests and multivariate logistic regressions were performed by using Stata 12.0, as needed. RESULTS: The prevalence of 12-month suicidal ideation was 4.29%, there was no significant difference between males and females [5.04% vs 3.62%, Adjusted Odds Ratio (AOR) = 0.83, p = 0.351]. Several risk factors for suicidal ideation were confirmed, including being unmarried (AOR = 1.55, p = 0.030), having depression symptoms (AOR = 2.33, p < 0.001), having other insurance (AOR = 1.83, p = 0.01) or no insurance (AOR = 1.73, p = 0.024). In addition, several influence factors were significantly different in males and females, such as being currently married (unmarried vs married, AOR = 1.84, p = 0.027, for females; no difference for males), feeling hopeless (hopless vs hopeful, AOR = 1.92, p = 0.06, for females; no difference for males), having other insurances (having other insurances vs having basic employee medical insurance, AOR = 1.92, p = 0.044, for males; no difference for females), having debts (having debts vs no debts, AOR = 2.69, p = 0.001, for males; no difference for females), currently smoking (smoking vs nonsmoking, AOR = 3.01, p = 0.019 for females, no difference for males), and currently drinking (drinking vs nondrinking, AOR =2.01, p = 0.022, for males; no difference for females). DISCUSSION AND CONCLUSION: These findings suggested that comprehensive suicide prevention strategies should be developed or strengthened in order to prevent suicide ideation in China, and the gender-specific differences need to be explored through further researches.

BACKGROUND: To effectively provide public health care for rural residents, the Ministry of Health formally unveiled the contract service policy in rural China in April 2013. As the counterpart to family medicine in some developed countries, the contract service established a compact between village doctors and local governments and a service agreement between doctors and their patients. This study is a rare attempt to explore the perspectives of health providers on the contract service policy, and investigate the demand side's attitude toward the public health services delivered under the contract policy. This evidence from Xinjian County, Jiangxi Province, the first and most representative pilot site of the contract service, could serve as a reference for policymakers to understand the initial effects of the policy, whereby they can regulate and amend some items before extending it to the whole country. METHODS: Official documents were collected and semi-structured interviews with human resources and villagers in Xinjian County were conducted in September 2013. A purposive sampling method was used, and eight towns from the total 18 towns in Xinjian County were selected. Ultimately, eight managers (one in each township health center), 20 village doctors from eight clinics, and 11 villagers were interviewed. A thematic approach was used to analyze the data, which reflected the people's experiences brought about by the implementation of the contract service policy. RESULTS: While the contract service actually promoted the supply side to provide more public health services to the villagers and contracted patients felt satisfied with the doctor-patient relationship, most health providers complained about the heavy workload, insufficient remuneration, staff shortage, lack of official identity and ineffective performance appraisal, in addition to contempt from some villagers and supervisors after the implementation of the contract service. CONCLUSIONS: Contract service is a crucial step for the government to promote public health services in rural areas. To inspire the positive perspective and optimal work performance of the health workforce, it is imperative for the Chinese government to fortify financial support to health providers, adopt an advanced management model and escalate administrative capacity.

BACKGROUND: Bullying is a growing concern worldwide. However, there is insufficient research on the prevalence and factors associated with different forms of bullying in a large sample of Chinese adolescents. This study aims to investigate the prevalence and associated factors of bullying victimization among Chinese high school students. METHODS: Data from the 2020-2021 cross-sectional survey of the DYH program were used. A total of 8203 high school students were randomly selected from all 17 cities in Shandong Province, China. Bullying victimization was measured using two separate questions and identified into three types: school bullying victims, cyberbullying victims, and combined bullying victims. The multinomial logit model was used to explore the factors related to bullying victimization. RESULTS: The prevalence of bullying victimization was 11.59 %, with 4.04 % of school bullying, 3.37 % of cyberbullying, and 4.18 % of combined bullying. Smoking was negatively associated with bullying victimizations. Male, physical exercise, peer relationships, and obsessive-compulsive symptoms were significantly associated with school bullying victims and combined victims. Watching TV was an influencing factor for school bullying victims and cyberbullying victims. Single-child households, family economic status, drinking alcohol, parent-child relationships, and paranoia were correlated with different types of bullying victimization. LIMITATIONS: The cross-sectional design limited the examination of causal inferences. CONCLUSION: We should pay more attention to cyberbullying victimization, which has become as common as school bullying victimization among high school students. The associated factors explored in this study may contribute to understanding bullying victimizations and designing bullying intervention strategies among high school students in China.

OBJECTIVE: To investigate the association between diabetes knowledge and diabetes self-management (DSM) behaviors and to explore the influence mechanism between them among patients with type 2 diabetes mellitus (T2DM) based on health belief model in rural China. METHODS: This cross-sectional study included 483 participants with T2DM from 8 villages of 3 townships in Jiangsu Province. All participants completed a structured questionnaire, including demographic information, diabetes knowledge, DSM behaviors, health beliefs, and cognitive function. Multiple linear regression and mediation analysis were performed to analyze the association between diabetes knowledge and DSM behaviors, furthermore the mechanism between them. RESULTS: Diabetes knowledge and self-efficacy positively influenced DSM behaviors. Health beliefs multiply mediated the association between diabetes knowledge and DSM behaviors. Perceived behavioral barriers mediated the relationship between diabetes knowledge and DSM behaviors, where a suppression effect existed. A chain-mediated effect was found: diabetes knowledge affected perceived benefits, followed by self-efficacy, and finally DSM behaviors. CONCLUSION: Diabetes knowledge acquisition played an important role in improving DSM behaviors, and health beliefs multiply mediated the relationship between them. PRACTICE IMPLICATIONS: When designing interventions, health systems and health providers should refocus on diabetes knowledge, emphasize the benefits of self-management, and consider the barriers that patients may encounter.

Improving diabetes self-management (DSM) is facing real-world challenges among people with type 2 diabetes mellitus (T2DM) who have a low education level in resource-limited areas. This study aimed to investigate whether diabetes knowledge could predict glycemic levels in people with T2DM in rural China. This analytical cross-sectional study recruited 321 people with T2DM from eight villages by purposive sampling at baseline. After 10 months, 206 patients completed the follow-up survey and HbA1c tests, with a response rate of 64.17% (206/321). Multiple regression analysis was employed to explore the correlation between diabetes knowledge and HbA1c levels. The patient's diabetes knowledge was significantly negatively correlated with HbA1c levels before and after controlling for covariates in both hierarchical multiple regression and multiple logistic regression (p < 0.01). In addition, other influencing factors, including sex, age, marital status, employment status, income, and HbA1c levels at baseline, were also identified. Diabetes knowledge could predict HbA1c levels significantly among patients with low education levels in rural China. Therefore, interventions on improving diabetes knowledge need to be strengthened for patients in rural China so that they can improve their health outcomes and reduce the disease burden.

Metal clusters have become increasingly important in various applications, with ligands playing a crucial role in their construction. In this study, we synthesized a bimetallic cluster, Ag6 Cu8 (C=CAr)14 (DPPB)2 (Ag6 Cu8 ), using a rigid acetylene ligand, 3,5-bis(trifluoromethyl)phenylacetylide. Through single-crystal structure characterization, we discovered that the butterfly-shaped Ag2 Cu2 motifs were subject to distortion due to steric hindrance imposed by the rigid ligand. These motifs assembled together through shared vertices and edges. Mass spectrometry analysis revealed that the primary fragments detected during electrospray ionization (ESI) testing corresponded to the Ag2 Cu2 motifs. Furthermore, we conducted a comprehensive investigation of the cluster's solution properties employing 31 P NMR, UV-vis absorption, and photoluminescent measurements. In contrast to previously reported Ag/Cu bimetallic clusters protected by flexible ligands, Ag6 Cu8 protected by rigid ligands exhibited intriguing room temperature fluorescence properties alongside excellent thermal stability. DFT calculations on Ag6 Cu8 and Ag6 Cu8 with the rigid aromatic ring removed revealed that the presence of the rigid aromatic ring can lower the electronic energy levels of the cluster, and reduce the energy gap from 4.05â eV to 3.45â eV. Moreover, the rigid ligand further suppressed the non-radiative transition process, leading to room temperature fluorescence emission.
RESUMEN
BACKGROUND: This study aimed to explore the relationship between communication skills, health service quality, and patient trust in primary health services. METHOD: This study was conducted in village clinics in rural China. A simple random sampling method was used to select volunteer village clinics and patients. In total, 574 participants from 25 village clinics were selected with the help of local health officers and village doctors. The response rate was 90%. Statistical analyses (hierarchical linear regression analysis and a structural equation model) were performed to analyze the data. RESULTS: Patient trust in doctors in rural primary health was influenced by patient perceptions of doctors' communication skills and health service quality. However, health service quality fully mediated the relationship between doctors' communication skills and patient trust in village clinics. In other words, doctors' communication skills indirectly influence patients' trust in doctors. CONCLUSIONS: This study found a link between doctors' communication skills and patient trust. The findings suggest that health managers and doctors should attach great value to communication skills and health service quality in promoting the rural doctor-patient relationship. Moreover, the relationship between doctors and patients should be considered when reforming the primary health system.

Historically, cooperative medical insurance and village doctors are considered two powerful factors in protecting rural residents' health. However, with the central government of China's implementation of new economic policies in the 1980s, cooperative medical insurance collapsed and rural residents fell into poverty because of sickness. In 2009, the New Rural Cooperative Medical Insurance (NRCMI) was implemented to provide healthcare for rural residents. Moreover, the National Basic Drug System was implemented in the same year to protect rural residents' right to basic drugs. In 2013, a village doctor contract service was implemented after the publication of the Guidance on Pilot Contract Services for Rural Doctors. This contract service aimed to retain patients in rural primary healthcare systems and change private practice village doctors into general practitioners (GPs) under government management. OBJECTIVES: This study investigates the factors associated with rural residents' contract behavior toward village doctors. Further, we explore the relationships between trust, NRCMI reimbursement rate, and drug treatment effect. We used a qualitative approach, and twenty-five village clinics were chosen from three counties as our study sites using a random sampling method. A total of 625 villagers participated in the investigation. Descriptive analysis, chi-squared test, t-test, and hierarchical logistic analyses were used to analyze the data. RESULTS: The chi-squared test showed no significant difference in demographic characteristics, and the t-test showed a significant difference between signed and unsigned contract services. The results of the hierarchical logistic analysis showed that trust significantly influenced patients' willingness to contract services, and the drug treatment effect and NRCMI reimbursement rate moderated the influence of trust. CONCLUSION: Our findings suggest that the government should aim to strengthen trust in the doctor-patient relationship in rural areas and increase the NRCMI reimbursement rate. Moreover, health officers should perfect the contract service package by offering tailored contract services or expanding service packages.

BACKGROUND: Effective screening is important for public mental health services. Although the primary care PTSD screen for DSM-5 (PC-PTSD-5) is useful in screening for post-traumatic stress disorder (PTSD) in adults, its reliability and validity for use in children remain unclear. This study aimed to examine the performance characteristics of the Chinese PC-PTSD-5 for children in children aged 8 to 16 years. METHODS: 4,022 rural children from Grades 4 to 9 in China were included in this study. All participants were assessed for PTSD using the Chinese PC-PTSD-5 for children and the PTSD Checklist for DSM-5 (PCL-5), and assessed for anxiety using the Chinese version of the State Anxiety Scale for Children (CSAS-C), and for depression using the Children's Depression Inventory - Short Form (CDI-S). The performance characteristics of the PC-PTSD-5 for children were evaluated using receiver operating characteristic analyses. RESULTS: The mean scores on the PCL-5 and the PC-PTSD-5 were 17.45 (SDâ¯=â¯14.78) and 1.78 (SDâ¯=â¯1.33), respectively. There was a significant correlation between the PC-PTSD-5 and PCL-5 (râ¯=â¯0.54, p < 0.001), and small but significant correlations of the PC-PTSD-5 with the CSAS-C (râ¯=â¯0.31, p < 0.001) and CDI-S (râ¯=â¯0.27, p < 0.001). In this study, 2 and 3 were both found to be acceptable cutoff values. A cutoff value of 2 yielded a sensitivity of 0.87 and a specificity of 0.52, while a cutoff of 3 had sensitivity =â¯0.57, and specificity =â¯0.77. LIMITATIONS: A clinical interview was not used to validated diagnostic findings. CONCLUSIONS: The reliability and validity of the Chinese PC-PTSD-5 were statistically acceptable for screening for probable PTSD in children. Additionally, the Chinese PC-PTSD-5 had a favorable sensitivity at a cut off 2 and a favorable specificity at a cut off 3, based on PCL-5 results.

BACKGROUND: Early distinguishing the cognitive impairment from healthy population is crucial to delay the progression of mild cognitive impairment (MCI) and Alzheimer disease (AD). Test Your Memory (TYM) has been proved to be a valid and reliable screening instrument for AD and MCI. This study aimed to develop a culturally appropriate and functional Standard Mandarin Chinese translation of the TYM, and to evaluate its reliability and validity in detecting AD and MCI in Chinese. METHODS: 182 subjects with AD/MCI and 55 healthy controls were recruited to participate in this study, and everyone undergo the test of Standard Mandarin Chinese version of the TYM (TYM-CN), Mini-mental State Examination (MMSE), Montreal cognitive assessment (MoCA-BJ), and Clinical Dementia Rating (CDR) Scale. Concurrently, all the subjects with AD/MCI received the general physical and neurologic examinations, extensive laboratory tests, and brain computed tomography/magnetic resonance imaging (MRI). Of which, 90 subjects were asked to complete the re-test of TYM-CN at 3 weeks after the initial visit. Intra-class correlation coefficient (ICC) and Cronbach's alpha was used to assess the test-retest reliability and the internal consistency. The validity, sensitivity and specificity were also analyzed. One-way analysis of variance, χ2 test, correlation analysis, and receiver operating characteristic curve (ROC) analysis were employed, as needed. RESULTS: The total scores of TYM-CN was 43.89 ± 3.44, 40.88 ± 4.38, and 29.12 ± 7.44 (p < 0.01) for healthy controls group, MCI group, and AD group, respectively. The ICC for 11 items of TYM-CN ranged from 0.863 (copying) to 0.994 (anterograde), and that of the total scale was 0.993, suggesting an excellent reliability. Furthermore, the significant correlation was also found between TYM-CN and MMSE (r = 0.76), MoCA-BJ (r = 0.74), and CDR scores (r = 0.76), indicating a good validity. A TYM-CN scores ≤ 39.5 had 95% sensitivity and 95% specificity in differentiating AD from healthy controls, and that ≤ 43.5 had 75% sensitivity and 91% specificity in distinguishing MCI from healthy controls, respectively. CONCLUSION: The reliability and validity of the TYM-CN are statistically acceptable for the evaluation of cognitive impairment, which may contribute to neuropsychological tests for the diagnosis of AD and MCI from healthy controls in China.
