Abstract
PURPOSE Little is known about the level of work-related stress in nurses in China.This study compared the level of work-related stress between female nurses working in psychiatric and general hospitals in China. DESIGN AND METHODS A descriptive comparative cross-sectional design was used.A consecutive sample of nurses from two psychiatric hospitals (N = 297) and a medical unit (N = 408) of a general hospital completed a written survey including socio-demographic data and a measure of work-related stress (Nurse Stress Inventory). FINDINGS Compared to the nurses working in the general hospital, those working in the psychiatric setting had a higher level of stress in the domains of working environment and resources (p < .001) and patient care (p < .001), but lower workload and time (p < .001).Multivariate analyses revealed that college or higher level of education(b = .1, p < .001), exposure to violence in the past 6 months (b = .2, p < .001),longer working experience, and working in psychiatric hospitals were associated with high work-related stress (b = .2, p < .001). PRACTICE IMPLICATIONS Considering the harmful effects of work-related stress, specific stress management workshops and effective staff supportive initiatives for Chinese nurses are warranted.

Abstract
BACKGROUND While several studies have found executive function deficits in adults and maltreated children with posttraumatic stress disorder (PTSD), there are few data on executive function in children and adolescents with PTSD related to natural disasters. The objective of this study was to test executive function changes over time in children and adolescents with PTSD after a magnitude 8.0 earthquake in Sichuan, China. METHOD A sample of 34 children and adolescents with diagnosed PTSD following the Sichuan earthquake and 66 matched controls exposed to the same earthquake but without PTSD participated in the study. Executive function was assessed using a battery of interviewer-rated neuropsychological tests and the guardian-rated Behavior Rating Scale of Executive Function (BRIEF) at 4- and 12-month after the earthquake. RESULTS Children and adolescents with PTSD performed similar to controls in executive function at 4-months after the earthquake. Both groups improved significantly in similar domains of cognition during the following 8 months. The PTSD group exhibited daily deficits in emotional control compared with the controls at the 4-month assessment, but the differences disappeared during the following 8 months. CONCLUSIONS Children and adolescents with PTSD related to a natural disaster have deficits only in the emotional control domain of executive function compared with controls exposed to the same disaster, but even these deficits did not persist.

Abstract
PURPOSE Little is known about quality of life (QOL) in Chinese patients with bipolar disorder (BD) in remission (euthymia). This study examined the QOL of such a cohort of BD patients and its demographic, clinical, and cognitive correlates. DESIGN AND METHODS Forty-seven euthymic BD patients and 47 matched healthy controls formed the study sample. Socio-demographic characteristics, prospective memory, retrospective memory, intelligence quotient, and executive functioning were measured in all participants together with patients’ psychopathology ratings. FINDINGS Multivariate analyses revealed that compared to controls, euthymic BD patients had significantly lower satisfaction with physical QOL domain. Only subthreshold depressive symptoms independently contributed to reduced satisfaction with physical and environmental QOL domains, whereas no variable predicted its psychological and social domains. PRACTICE IMPLICATIONS Contrary to findings from Western settings, demographic variables and cognitive deficits had no associations with any QOL domain in euthymic Chinese BD patients. Control of subthreshold depressive symptoms in euthymic BD patients might enhance their QOL.

Abstract
This study examined the frequency of violence on nurses in Chinese psychiatric hospitals and explored its risk factors and impact on nurses' quality of life (QOL). A survey was conducted with 387 frontline psychiatric nurses in China. Information about experience of workplace violence in the past 6 months, type of workplace violence, and demographic characteristics was collected by a questionnaire. Altogether 319 (82.4%) of 387 nurses reported having experienced at least one type of violent event in the past 6 months. The prevalence of sexual assault, physical and verbal harassment was 18.6%, 61.5% and 78.6%, respectively. Compared to those with no exposure to violence, nurses who were exposed to violence had lower QOL in both the physical and mental domains. Significant predictors of violence against nurses are male sex, receiving college level or higher education and working on rotating duty were independently associated with high risk of violence. Workplace violence against psychiatric nurses commonly occurs in China. Considering the deleterious effects of violence, comprehensive strategies from the perspective of nursing education and training, organizational policy, patient care and staff support are recommended to promote occupational safety in psychiatric settings in China.

Abstract
OBJECTIVES Bipolar disorder is often misdiagnosed as major depressive disorder. Such misdiagnosis partly depends on the type of treatment setting. This study compared general hospital psychiatric units with psychiatric hospitals in China with respect to basic demographic and clinical characteristics of patients with unrecognised bipolar disorder who are treated for major depressive disorder. METHODS Patients treated for major depressive disorder were consecutively examined in 13 health centres (6 general hospital psychiatric units and 7 psychiatric hospitals) in China. Their socio-demographic and clinical features were recorded using a standardised protocol and data collection procedure. The DSM-IV diagnoses were established using the Mini-International Neuropsychiatric Interview. RESULTS Of the 1487 patients included in the study, 309 (20.8%) were diagnosed with bipolar disorder. There was no significant difference between general hospital psychiatric units and psychiatric hospitals in the ratio of all types of unrecognised bipolar disorders (χ2 = 0.008, degrees of freedom = 1, p = 0.9) and bipolar II disorders (χ2 = 3.1, degrees of freedom = 1, p = 0.08). The proportions of unrecognised bipolar I disorders (χ2 = 4.1, degrees of freedom = 1, p = 0.04) differed significantly between the 2 types of study site. Multivariate analyses showed that patients with bipolar I disorders with more seasonal depressive episodes were more likely to receive treatment in general hospital psychiatric units (odds ratio = 3.3, 95% confidence interval = 1.1-9.8). CONCLUSION Patients with bipolar I disorders receiving treatment in general hospital psychiatric units had different clinical characteristics compared to their counterparts treated in psychiatric hospitals in China.

Abstract
PURPOSE Little is known about gender differences associated with major depressive disorder (MDD) in China. This study examined gender differences associated with other demographic and clinical characteristics and psychotropic drug treatment in Chinese patients with MDD. METHODS A total of 1178 patients with MDD from 13 psychiatric hospitals or psychiatric units of general hospitals in China nationwide were enrolled. Cross-sectional data including patients' demographic and clinical characteristics and prescriptions of psychotropic medications were recorded using a standardized protocol and data collection procedure. RESULTS The sample consisted of 793 female and 385 male patients. Univariate analyses revealed that male patients were younger than female patients, had a younger age of onset of depression, had less lifetime depressive episodes and had more bipolar features (i.e. patients who screened positive for hypomanic symptoms on the 32-item Hypomania Checklist, but did not meet the diagnostic criteria for DSM-IV bipolar disorders as measured by the Mini International Neuropsychiatric Interview). Also, men were more likely to be employed than women and less likely to have depressive episodes following stressful life events. In multivariate analyses, being employed, having bipolar features and not having depressive episodes following stressful life events were independently associated with being a male patient with major depressive disorder. There was no difference in use of psychotropic medications by gender. CONCLUSIONS Most gender differences in MDD patients in this study are not consistent with findings of Western studies suggesting that gender differences in MDD may be determined by both biological and sociocultural differences among ethnically different patient populations.

Abstract
BACKGROUND In Hong Kong, older Chinese adults generally have a low level of education. This study examined the effect of education on very mild Alzheimer's disease (AD), as quantified by Clinical Dementia Rating (CDR) scale (CDR 0.5 versus 0), in a Chinese community. The Cantonese version of the Mini-Mental State Examination (C-MMSE) was used to estimate cognitive abilities that were related to the level of education, and that in turn serve as protective factors for AD. METHODS A total of 788 community-dwelling older adults (383 CDR 0 and 405 CDR 0.5) were recruited in this cross-sectional study, which was derived from a population-based prevalence project. The participants' number of years of education and C-MMSE scores were used to predict their CDR scores using logistic regression and the mediation effects of C-MMSE scores were analyzed. RESULTS Consistent with previous studies, the chance of being rated as having very mild AD increased with age, but decreased with years of education, among the older adult community of Hong Kong. The effect of education on very mild dementia was weakened substantially when C-MMSE scores were included as mediating variables. CONCLUSIONS The findings indicate that the protective effects of education on dementia were mediated by an enhancement of older adults' performance on some C-MMSE items, including attention and orientation to time and place.

Abstract
INTRODUCTION Prospective memory refers to the ability to remember to do something in the future. To date, little is known about prospective memory deficits in bipolar disorder (BD) in remission (euthymia). This study examined the nature and correlates of prospective memory in these patients. METHODS Forty-seven euthymic BD patients and 47 matched healthy controls formed the study sample. Socio-demographic and basic clinical characteristics, prospective memory (Cambridge Prospective Memory Test [CAMPROMPT]), retrospective memory (immediate Logical Memory subtests of the Wechsler Memory Scales-Revised [WMS-R]), IQ (Raven's Progressive Matrices) and executive functioning (Wisconsin Card Sorting Test) were measured in all participants; patients' symptoms were rated with the 17-item Hamilton Depression Rating Scale and the 11-item Young Mania Rating Scale. RESULTS Patients performed significantly worse on time-based prospective memory compared to controls. Multivariate analyses revealed that patients' lower score on Raven's Progressive Matrices significantly contributed to poor performance on time-based prospective memory, whereas lower scores on WMS-R Logical Memory subtest contributed to poor performance on event-based prospective memory; in controls, lower education level and older age significantly contributed to poor performance on time-based and event-based prospective memory, respectively. DISCUSSION Prospective memory deficits persist in remitted BD patients suggesting that prospective memory impairment constitutes a trait deficit in BD.

Abstract
BACKGROUND To date there has been no large-scale international study that examined the use of clozapine in older patients with schizophrenia. This study examined the use of clozapine and its demographic and clinical correlates in older patients with schizophrenia in East Asia during the period between 2001 and 2009. METHOD Information on 1,157 hospitalized patients with schizophrenia aged 50 or older in five East Asian countries and territories (China, Hong Kong, Korea, Singapore and Taiwan) was extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) project. Socio-demographic and clinical characteristics and prescription of psychotropic medications were recorded. RESULTS Clozapine was prescribed for 20.6% of the pooled sample; 19.0% in 2001, 19.4% in 2004 and 22.9% in 2009. Multiple logistic regression analysis of the whole sample revealed that patients taking clozapine had a longer duration of illness, more negative symptoms and were less likely to receive first generation antipsychotic and anticholinergic drugs, but more likely to report weight gain compared to those not receiving clozapine. Compared to those in other sites, older patients in China were more likely to receive clozapine. CONCLUSIONS The prescription of clozapine for older Asian schizophrenia inpatients has remained at a stable level during the past decade. The appropriateness of use of clozapine in China needs to be further explored.

Abstract
Previous studies suggested that patients with mild cognitive impairment (MCI) or dementia can have impaired and declining financial skills and abilities. The purpose of this study is to test a clinically applicable method, based on the contemporary legal standard, to examine directly the mental capacity to make financial decisions and its component decision-making abilities among patients with MCI and early dementia. A total of 90 patients with mild Alzheimer disease (AD), 92 participants with MCI, and 93 cognitively normal control participants were recruited for this study. Their mental capacity to make everyday financial decisions was assessed by clinician ratings and the Chinese version of the Assessment of Capacity for Everyday Decision-Making (ACED). Based on the clinician ratings, only 53.5% were found to be mentally competent in the AD group, compared with 94.6% in the MCI group. However, participants with MCI had mild but significant impairment in understanding, appreciating, and reasoning abilities as measured by the ACED. The ACED provided a reliable and clinically applicable structured framework for assessment of mental capacity to make financial decisions.

Abstract
INTRODUCTION Little is known about the prescription patterns of adjunctive antidepressants in Asian schizophrenia patients. This study aimed to examine trends in the use of antidepressants and their demographic and clinical correlates in the treatment of schizophrenia in Asia between 2001 and 2009. METHODS A total of 6,761 hospitalized schizophrenia patients in nine Asian countries and territories were examined: 2,399 in 2001, 2,136 in 2004 and 2,226 in 2009. Patients' socio-demographic and clinical characteristics and prescriptions of psychotropic drugs were recorded using a standardized protocol and data collection procedure. RESULTS The proportion of antidepressant prescription was 6.8% in the whole sample; 5.3% in 2001, 6.5% in 2004 and 8.7% in 2009. There were wide inter-country variations at each survey ranging from 0.9% in Hong Kong to 15.3% in Singapore in 2001; from 1.9% in Korea to 15.4% in Singapore in 2004; and from 2.7% in Japan to 22.0% in Singapore in 2009. Multiple logistic regression analysis of the whole sample revealed that patients on antidepressants were younger, more likely to receive benzodiazepines and have significant extrapyramidal side-effects and less likely to have significant positive symptoms. DISCUSSION Unlike findings in Western countries, adjunctive antidepressant prescription for schizophrenia was not common in Asia. The frequency of antidepressant prescription varied among countries and territories, suggesting that a host of clinical and socio-cultural factors played a role in determining antidepressant use in Asia.

Abstract
BACKGROUND Developing accurate and time-efficient tools to measure depressive symptoms is important for research and clinical practice. This study aimed to test the psychometric properties of the Chinese version of the 16-item Quick Inventory of Depressive Symptomatology - Clinician Rating (C-QIDS-C) and Self-Report (C-QIDS-SR). METHODS This study included 998 patients with major depressive disorder (MDD) established using the Mini International Neuropsychiatric Interview (MINI). The severity of depressive symptoms was assessed using the Hamilton Rating Scale for Depression (HAMD), C-QIDS-C and C-QIDS-SR at baseline and 6 weeks later. RESULTS Internal consistency (Cronbach's alpha) ranged from 0.73 to 0.82 for C-QIDS-C and C-QIDS-SR at both the baseline and exit. The involvement and energy domains at baseline, and sad mood, concentration/decision making, self outlook, involvement and agitation/retardation domains at exit had the highest item-total correlations across the two C-QIDS scales. The C-QIDS-C and C-QIDS-SR total scores were highly correlated with the HAMD total score at both baseline (r=0.61, p<0.01 and r=0.54, p<0.01, respectively) and exit (r=0.75, p<0.01 and r=0.72, p<0.01, respectively). The C-QIDS-C, C-QIDS-SR and HAMD were equally sensitive to change of depressive symptoms, suggesting high concurrent validity. The C-QIDS-C and C-QIDS-SR showed uni-dimensional measurement properties in exploratory factor analyses at both baseline and exit. CONCLUSIONS The C-QIDS-C and C-QIDS-SR have excellent psychometric properties and are sensitive measurement of symptom severity in MDD.

Abstract
INTRODUCTION There is an increasing interest in the patterns of mental health care of people with serious mental illnesses in China, where outpatient and community-based care are not fully developed and long-term hospitalization is still not uncommon. Comparison of sociodemographic and clinical characteristics of long-term and short-term inpatients diagnosed with schizophrenia can be informative about pattern of treatment and their relationship to services needs. METHODS Seventy-three long-term schizophrenia inpatients (current length of stay of more than 5 years) were compared to 116 short-term schizophrenia inpatients (current length of stay of 30 days or less) assessed with the Individual Background Questionnaire, the Positive and Negative Syndrome Scale (PANSS) and the Social Support Rating Scale (SSRS). RESULTS There was no significant difference between the groups on the total PANSS symptom score but the short-term inpatients scored significantly higher than their long-term counterparts on the Positive Syndrome sub-scale and the SSRS and lower on the Negative Syndrome sub-scale. DISCUSSION Differences in symptomatology and social functioning may be related to better medication adherence and more extended social isolation among long-term inpatients while the increased positive symptoms are likely to reflect more acute disease process in short-term inpatients, and possibly poorer medication adherence. These differences may be especially pronounced in developing countries like China in which community-based services need to be more fully developed to facilitate medication adherence and prevent relapse, and to support community adjustment of socially isolated patients who otherwise require hospitalization.

Abstract
OBJECTIVE This study surveyed the use of anticholinergic medications (ACMs) in older Asian patients with schizophrenia and examined its demographic and clinical correlates. METHOD A total of 1452 hospitalized patients with schizophrenia aged 55 years or older in nine Asian countries and territories were surveyed between 2001 and 2009. The cross-sectional data of patients' socio-demographic and clinical characteristics and the prescriptions of antipsychotic drugs and ACM were recorded using a standardized protocol and data collection procedure. RESULTS The frequency of ACM prescription was 64.6% in the pooled sample, with 72.4%, 61.9%, and 59.5% in 2001, 2004, and 2009, respectively. Multiple logistic regression analysis of the whole sample revealed that patients on ACM had a higher dose of antipsychotic medications, and were more likely to have extrapyramidal side effects and receive first-generation antipsychotic medications. CONCLUSIONS Anticholinergic medications were frequently used in older Asian patients with schizophrenia. Considering the potential side effects of ACM, the rationale for their widespread use in this patient population should be revisited.

Abstract
OBJECTIVES Bipolar disorder (BD) is frequently misdiagnosed as major depressive disorder (MDD), which may lead to inappropriate treatment and poor outcomes. This study aimed to compare demographic and clinical features between patients with MDD and those with BD, but being misdiagnosed as MDD, in China. METHODS A total of 1487 patients diagnosed with MDD were consecutively evaluated in 13 psychiatric hospitals or psychiatric units of general hospitals nationwide in China. The patients' sociodemographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The Mini-International Neuropsychiatric Interview (MINI) was used to establish DSM-IV diagnoses, and identify patients with MDD and those with BD, but being misdiagnosed with MDD. RESULTS The proportions of BD (all types), bipolar I disorder (BD-I), and bipolar II disorder (BD-II) misdiagnosed as MDD in clinical practice were 20.8%, 7.9%, and 12.8%, respectively. Multiple logistic regression analyses revealed that compared to MDD patients, BD-I was characterized by more atypical depressive features (increased appetite, increased sleep, and weight gain) [odds ratio (OR) = 2.0, 95% confidence interval (CI): 1.2-3.2], more psychotic symptoms (OR = 2.1, 95% CI: 1.3-3.5), more lifetime depressive episodes (OR = 1.1, 95% CI: 1.1-1.2), and earlier age of onset (OR = 0.97, 95% CI: 0.9-0.99); BD-II was characterized by more psychotic symptoms (OR = 2.1, 95% CI: 1.4-3.1) and earlier age of onset (OR = 0.96, 95% CI: 0.9-0.97). In addition, compared to BD-II patients, BD-I patients were characterized by more frequent depressive episodes per year (OR = 3.1, 95% CI: 1.5-6.6). CONCLUSIONS Depressive episodes in the context of BD-I and BD-II, among those who were misclassified as MDD, present some different clinical features compared to MDD. This finding should be taken into account in guiding diagnostic practices in China.

Screening for bipolar disorder with the Mood Disorders Questionnaire in patients diagnosed as major depressive disorder - the experience in China. J Affect Disord 2012; 141:40-6. [PMID: 22436092 DOI: 10.1016/j.jad.2012.02.035] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2012] [Revised: 02/22/2012] [Accepted: 02/22/2012] [Indexed: 10/28/2022]
Abstract
BACKGROUND Bipolar disorder (BD) is often misdiagnosed as a major depressive disorder (MDD). This study aimed to test the usefulness of the screening tool, the Mood Disorders Questionnaire (MDQ), to identify BD patients misdiagnosed as MDD in Chinese clinical settings. METHODS A total of 1487 patients treated for MDD were consecutively examined in 13 mental health centers in China. The patients' socio-demographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The MDQ was completed by patients to identify symptoms characteristic of BD. DSM-IV diagnoses were established using the Mini International Neuropsychiatric Interview (MINI). RESULTS Three hundred-nine of the 1487 patients (20.8%) satisfied DSM-IV criteria for BD; 118 (7.9%) for BD-I and 191 (12.8%) for BD-II on the MINI. The optimal cut-off point on the MDQ to differentiate BD from MDD was 3, while cut-off points of 5 and 3 differentiated BD-I and BD-II from MDD, respectively. The maximum sensitivity was 0.31, 0.45 and 0.22 for differentiating BD, BD-I and BD-II from MDD, respectively. CONCLUSIONS The optimal cutoff points of the MDQ for screening BD in Chinese patients originally diagnosed as MDD were considerably lower than those in earlier studies. The routine clinical use of the MDQ as a screening scale for BD in Chinese patients treated for MDD does not seem to be justified.

Abstract
OBJECTIVE Bipolar disorder (BD) is frequently misdiagnosed as major depressive disorder (MDD), which may lead to inappropriate treatment and poor outcomes. This study aimed to examine prescribing patterns of antidepressants, antipsychotics and mood stabilizers in BD patients misdiagnosed with MDD in China. METHODS A total of 1487 patients originally diagnosed with MDD were consecutively screened for diagnostic revision in 13 psychiatric hospitals or psychiatric units of general hospitals in China nationwide. The patients' sociodemographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. The Mini International Neuropsychiatric Interview (MINI) was used to establish DSM-IV diagnoses. Data on psychotropic prescriptions were collected by a review of medical records. RESULTS Three hundred and nine of the 1487 patients (20.8%) fulfilled DSM-IV criteria for BD; 118 (7.9%) for BD-I and 191 (12.8%) for BD-II on the MINI. Of the BD patients (n = 309), 227 (73.5%) received any use of antidepressants, 73 (23.6%) antipsychotics and 33 (10.7%) mood stabilizers. In multiple logistic regression analyses, compared with those with MDD, patients with BD-I were more likely to receive antidepressants (OR 1.7, 95% CI 1.1-2.8, p = 0.02), antipsychotics (OR 1.6, 95% CI 1.04-2.5, p = 0.04) and mood stabilizers (OR 3.9, 95% CI 2.1-7.2, p < 0.001), whereas patients with BD-II were more likely to receive mood stabilizers (OR 2.4, 95% CI 1.3-4.4, p = 0.003). There was no difference in the use of antidepressants (OR 1.1, 95% CI 0.8-1.5, p = 0.7) and antipsychotics (OR 1.3, 95% CI 0.9-1.9, p = 0.2) between BD-II and MDD. In addition, there was no difference between BD-I and BD-II in any use of antidepressants, antipsychotics and mood stabilizers. CONCLUSIONS The prescription of antidepressants for BD patients misdiagnosed with MDD is very common, and only a very small proportion of patients received guideline-concordant treatment. Considering the potentially hazardous effects of inappropriate pharmacotherapy in this population, continuing education and training addressing the correct diagnosis of BD and rational use of psychotropic medications are needed in China.

Abstract
Background Little has been known about the demographic and clinical features of the melancholic subtype of major depressive disorder (MDD) in Chinese patients. This study examined the frequency of melancholia in Chinese MDD patients and explored its demographic and clinical correlates and prescribing patterns of psychotropic drugs. Methods A consecutively collected sample of 1,178 patients with MDD were examined in 13 psychiatric hospitals or psychiatric units of general hospitals in China nationwide. The cross-sectional data of patients’ demographic and clinical characteristics and prescriptions of psychotropic drugs were recorded using a standardized protocol and data collection procedure. The diagnosis of the melancholic subtype was established using the Mini International Neuropsychiatric Interview (MINI). Medications ascertained included antidepressants, mood stabilizers, antipsychotics and benzodiazepines. Results Six hundred and twenty nine (53.4%) of the 1,178 patients fulfilled criteria for melancholia. In multiple logistic regression analyses, compared to non-melancholic counterparts, melancholic MDD patients were more likely to be male and receive benzodiazepines, had more frequent suicide ideations and attempts and seasonal depressive episodes, while they were less likely to be employed and receive antidepressants and had less family history of psychiatric disorders and lifetime depressive episodes. Conclusions The demographic and clinical features of melancholic MDD in Chinese patients were not entirely consistent with those found in Western populations. Compared to non-melancholic MDD patients, melancholic patients presented with different demographic and clinical features, which have implications for treatment decisions.

Abstract
BACKGROUND: The paper addressed a unique challenge for public health and community research in rural China, i.e., the very large percentage of young adults that comprises a highly mobile working population that has been an essential component of the country's economic transformation. Fluid local demographic patterns potentially have a substantial impact on sample representativeness and data validity. METHODS: This report is based upon a cross sectional survey with face-to-face interviews of residents aged 16-34 years in rural communities of Mianyang, Sichuan Province, China. Two waves of fieldwork and other strategies were adopted in response to recruitment challenges. RESULTS: 1654 of 3008 potential participants took part in the study; this constituted 98% of those individuals approached and 55% of the persons enumerated in the local household registration system (hukou). Analyses revealed substantial differences among those who were interviewed during September and October 2005, versus those seen during the Chinese Lunar New Year of 2006 when many migrant workers and students returned to their homes. Both groups together differed from those who were unavailable during either recruiting episode. DISCUSSION AND CONCLUSIONS: We discuss potential responses to associated methodological challenges, including, (1) permanent hukou mismatches; (2) temporary hukou mismatches; (3) difficulties faced by potential participants to fully understand the purpose of research, the informed consent process, and specific research questions; and (4) appreciation of the importance of local social networks, as they pertain in particular to rural China. These findings underscore that there may be a need to make "on-the-ground" adjustments to varying local conditions to maximize sample representativeness and data validity.

Characteristics and clinical correlates of prospective memory performance in first-episode schizophrenia. Schizophr Res 2012; 135:34-9.

Abstract
OBJECTIVE The aim of this study was to examine prospective memory (PM) and its socio-demographic, clinical, and neurocognitive correlates in first episode schizophrenia (FES). METHODS Fifty-one FES patients and 42 healthy controls formed the study sample. Time- and event-based PM (TBPM and EBPM) performance were measured with the Chinese version of the Cambridge Prospective Memory Test (C-CAMPROMPT). A battery of neuropsychological tests was also administered. Patients' clinical symptoms were evaluated with the Positive and Negative Symptom Scale (PANSS). RESULTS Patients performed significantly worse in both TBPM (8.7 ± 5.3 vs. 14.8 ± 3.5) and EBPM (11.3 ± 4.7 vs. 15.7 ± 2.7) than the controls. After controlling for age, gender, education level and neurocognitive test score, the difference in performance on the two types of PM tasks between patients and controls was no longer present. In multiple linear regression analyses, longer duration of untreated psychosis (DUP), lower scores of the Hopkins Verbal Learning Test-Revised (HVLT-R) and the categories completed of the Wisconsin Card Sorting Test (WCST-CC) and higher score of the Color Trails Test-2 (CTT-2) contributed to poorer TBPM performance, while lower score of HVLT-R, higher score of the perseverative errors of the Wisconsin Card Sorting Test (WCST-PE) and longer DUP contributed to worse performance on EBPM. CONCLUSIONS Both subtypes of PM are impaired in first-episode schizophrenia suggesting that PM deficits are an integral part of the cognitive dysfunction in the disease process.

Abstract
PURPOSE The aims of this study were to assess insight in Chinese patients with schizophrenia and to identify its relationship with sociodemographic and clinical factors, cognition, and quality of life (QOL). METHODS A cohort of 139 patients with clinically stable schizophrenia was selected by consecutively screening patients who had been diagnosed with schizophrenia and who were attending the outpatient department of a university-affiliated psychiatric hospital in China. Participants' sociodemographic and clinical characteristics, including psychotic and depressive symptoms and insight, as well as their social functioning, QOL, and flexibility of cognition, were assessed with standardized rating instruments. RESULTS Thirty-three patients (23.7%) had good insight into their illness. In univariate analyses, poor insight was associated with the positive, negative, and general symptom scores of the Positive and Negative Syndrome Scale (PANSS), and with higher scores on the physical and mental components of QOL. In multivariate analysis, poor insight was independently associated with a higher negative symptom score on the PANSS, a shorter length of illness, and with a high score on the physical components of QOL. CONCLUSIONS Poor insight is common in patients with clinically stable schizophrenia. In this study, insight was not associated with basic sociodemographic characteristics or had it any associations with depression or the flexibility of cognitive processes.
