RESUMO
The effectiveness of mental health care can be improved through coordinated and wide-scale outcome measurement. The International Consortium for Health Outcomes Measurement has produced collaborative sets of outcome measures for various mental health conditions, but no universal guideline exists for eating disorders. This Position Paper presents a set of outcomes and measures for eating disorders as determined by 24 international experts from professional and lived experience backgrounds. An adapted Delphi technique was used, and results were assessed through an open review survey. Final recommendations suggest outcomes should be tracked across four domains: eating disorder behaviours and cognitions, physical health, co-occurring mental health conditions, and quality of life and social functioning. Outcomes are collected using three to five patient-reported measures. For children aged between 6 years and 12 years, the measures include the Children's Eating Attitude Test (or, for those with avoidant restrictive food intake disorder, the Eating Disorder in Youth Questionnaire), the KIDSCREEN-10, and the Revised Children's Anxiety and Depression Screener-25. For adolescents aged between 13 years and 17 years, the measures include the Eating Disorder Examination Questionnaire (EDE-Q; or, for avoidant restrictive food intake disorder, the Nine-Item Avoidant Restrictive Food Intake Disorder Screener [NIAS]), the two-item Patient Health Questionnaire (PHQ-2), the nine-item Patient Health Questionnaire (PHQ-9), the two-item Generalised Anxiety Disorder (GAD-2), the seven-item Generalised Anxiety Disorder (GAD-7), and the KIDSCREEN-10. For adults older than 18 years, measures include the EDE-Q (or, for avoidant restrictive food intake disorder, the NIAS), the PHQ-2, the PHQ-9, the GAD-2, the GAD-7, the Clinical Impairment Assessment, and the 12-item WHO Disability Assessment Schedule 2.0. These questionnaires should be supplemented by information on patient characteristics and circumstances (ie, demographic, historical, and clinical factors). International adoption of these guidelines will allow comparison of research and clinical interventions to determine which settings and interventions work best, and for whom.

INTRODUCTION: A knowledge gap exists in the relationship between suicide and psychiatric hospitalization in Asia. This study investigated inpatient service utilization before suicide and suicide risk at different periods of hospitalization in Taiwan. METHODS: Using the National Health Insurance Research Database, we applied a nested case-control design with controls being alive on the date each case died by suicide. RESULTS: A total of 56 939 suicide cases and 1 138 780 controls were included (2:1 male-to-female ratio). Only 5.7% of suicide cases had a history of psychiatric hospitalization in the preceding year. Patients with a history of psychiatric hospitalization were associated with a higher risk of inpatient and postdischarge suicide than those without prior hospitalization. The risk was greatest in the first postdischarge week, decreased gradually, and remained significantly elevated over 7 years after discharge. The suicide risk increased more in females. Patients with affective disorders had higher inpatient and postdischarge suicide risks than those with schizophrenia spectrum disorders. DISCUSSION: A low rate of psychiatric hospitalization before suicide implies that inpatient treatment of psychiatric disorders could be enhanced. Community-based approaches to suicide prevention can improve the treatment utilization of those with suicide risk and bridge continuous care from hospital to community.

OBJECTIVE: To investigate natural- and unnatural-cause mortality at different follow-up time points in Taiwanese patients with anorexia nervosa (AN) and bulimia nervosa (BN). METHOD: In this longitudinal cohort study, 330,393 patients, including 2143 patients with AN, 13,590 with BN, and 20 times as many respective non-AN and non-BN patients, were followed up for 16 years. We performed conditional Cox regression survival analysis to examine the risk of mortality in the AN and BN groups relative to the comparison group. RESULTS: A total of 1242 patients died, including 101 and 343 patients with AN and BN, respectively. Mortality rates for AN and BN were 5.42 and 2.90 deaths per 1000 person-years, respectively. Compared with the non-AN group, the AN group had a significantly higher risk of both natural- and unnatural-cause mortality, and the BN group had a significantly higher risk of unnatural-cause mortality. Suicide was the most common cause of death, and suicide risk was significantly higher in both the AN and BN groups. All-cause mortality risk was the highest at the beginning of follow-up and markedly declined in the AN group. In the BN group, all-cause mortality risk was lower but stable at follow-up. The risk of unnatural-cause mortality remained high throughout the follow-up period for both the groups. CONCLUSIONS: Early detection and treatment for associated physical problems in patients with AN are crucial. Regular monitoring for unnatural-cause mortality events (mainly suicide) in AN and BN over time is also crucial. PUBLIC SIGNIFICANCE: AN had a significantly higher risk of both natural- and unnatural-cause mortality and BN had a significantly higher risk of death from unnatural causes. All-cause mortality risk was highest at the beginning of follow-up in AN, but unnatural-cause mortality risk remained high throughout the follow-up period for both groups. Our findings imply that early detection and treatment in AN and regular monitoring for unnatural-cause mortality events in AN and BN are crucial.

BACKGROUND: The Binge Eating Scale (BES) is a widely used measuring tool to assess binge eating problems in Western countries. However, the psychometric properties of such scales among cross-cultural youth groups are insufficient, and the factor structure continues to be debated; therefore, further research is needed. The aim of this study was to examine the properties of BES among overweight college students in Taiwan. METHODS: A cross-sectional design and convenience sampling were adopted to recruit 300 overweight students from five universities. A translated Traditional Chinese version of BES was used for the survey, and the validity of the scale was tested using the Confirmatory Factor Analysis (CFA) and Bulimic Investigatory Test, Edinburgh (BITE). The reliability was evaluated using internal consistency and test-retest reliability. RESULTS: The CFA results showed a reasonable model fit. The first-order two-factor model was consistent with that of the original BES and significantly correlated with the criterion of BITE score. Cronbach's α value, representing internal consistency reliability, and the intraclass correlation coefficient of repeated measures made one month apart were both 0.83, indicating good reliability and stability. Significant correlations were observed between the BES score and sex and BMI; however, no correlation was observed between BES scores and age. CONCLUSION: The BES presents sound psychometric properties, has good cross-cultural applicability, and can be used as a first-line screening tool by mental health professionals to identify the severity of binge eating behavior among overweight college students in Taiwan. It is recommended that participant diversity and obesity indicators be incorporated into the scale in the future to establish a universal psychometric tool.
The Binge Eating Scale (BES) is a screening tool that has been widely used to assess binge eating problems in Western countries. The current study aimed to test the validity and reliability properties of the BES among overweight college students in Taiwan. This research involved 300 overweight and obese college students while using a traditional Chinese-translated questionnaire in the survey and analyzed with subjective and scientific statistics methods afterward. The results indicated that BES has good cross-cultural applicability and can be used as a first-line measuring tool by mental health professionals to identify the severity of binge eating behavior among overweight or obese college students in Taiwan.
RESUMO
BACKGROUND: Binge eating (BE) is considered a marker of obesity and overweight and a significant characteristic of feeding and eating disorders. Despite the high prevalence of obesity on college campuses, the issue of BE among college students in Taiwan has received little attention. The aim of this study was to investigate BE behavior among overweight college students in Taiwan and associated factors. METHODS: This study utilized a cross-sectional survey. A total of 300 overweight college students were recruited through convenience sampling. Data were collected using a self-administered Binge Eating Scale (BES) and a body weight composition monitor (Model No. OMRON, HBF-126) and analyzed using descriptive statistics, correlation analysis, and regression analysis. RESULTS: The average BES score was 10.67 (SD = 6.66, 0-34). With a BES score of 17 as the cut-off point, 17.3% (n = 52) of the participants were found to have moderate or severe BE behavior. Analysis of the demographic and psychosocial data using Spearman's rho rank correlation coefficient revealed that sex, body mass index (BMI), uncontrolled eating, weight loss diets, academic stress, peer competition, interpersonal distress, and unpleasant or major life events were significantly correlated with BE behavior and its probability (rs = -0.14-0.15, p < 0.05). Furthermore, logistic regression analysis indicated that the odds ratio of the BES scores of female participants and those who stated to have experienced uncontrolled eating, weight loss diets, peer competition, and interpersonal distress was 1.05-6.04 times those of male participants and those without such experiences (p < 0.05). CONCLUSION: The study found that nearly one-fifth of participants presented moderate to severe levels of BE behaviors, and these were significantly correlated with sex and external environmental stress. This study suggests early intervention from campus psychological health personnel to provide proper therapy.
RESUMO
OBJECTIVE: To investigate the incidence and risk of renal-related complications in a nationwide cohort of Taiwanese patients with anorexia nervosa (AN). METHOD: This longitudinal cohort study analyzed the data of 43,951 individuals-comprising 2091 patients with AN and their controls matched (1:20) using propensity scores according to sex, age, degree of urbanization of residence, socioeconomic status, and year of diagnosis-from a population-based health insurance database; the study lasted 16 years. We used Kaplan-Meier curves to estimate the cumulative incidence of renal events. We also performed Cox proportional regression and constructed a risk model with death as a competing event (both adjusted for basic characteristics, renal diseases, and psychiatric comorbidities) to examine the risk of dialysis and renal outcomes in the AN group relative to the control group. RESULTS: In total, 204 and 10 patients with AN had renal-related outcomes and end-stage renal disease (ESRD), respectively. The cumulative incidence rates of all renal outcomes and ESRD in the AN group were 10.72% and .64%, respectively, at 10-year follow-up. Compared with the control group, the AN group had a significantly higher risk of acute dialysis (adjusted hazard ratio 2.10 [95% confidence interval 1.19-3.68]), hypokalemia, hypovolemia, nephritis, acute renal failure, and chronic renal failure. The AN group did not have a significantly higher risk of ESRD. DISCUSSION: The elevated risks of acute dialysis and some renal outcomes in AN highlight the importance of monitoring electrolyte imbalance and renal malfunctioning. PUBLIC SIGNIFICANCE: Malnutrition and purging behaviors may cause renal complications in patients with AN. In this longitudinal cohort study, we found that the 10-year cumulative incidence of all renal outcomes in AN was 10.72%, and that patients with AN had a two-fold higher risk of overall renal outcomes compared with those without AN. Our findings imply that weight restoration and ceasing purging behaviors are crucial for recovery from AN.

AIMS: We aimed to investigate the trajectories of absolute and relative risks of cause-specific mortality among patients discharged from inpatient psychiatric services. METHODS: We conducted a national matched cohort study (2002-2013) using data from the Taiwan National Health Insurance database linked to national cause-of-death data files. Patients discharged from inpatient psychiatric care without prior psychiatric hospitalizations were individually matched to 20 comparison individuals based on sex and age. The rates, rate differences, and relative risks (hazard ratios, HRs) of cause-specific mortality were calculated at six follow-up periods post-discharge. Cumulative mortality incidence was assessed at 5 years of follow-up. RESULTS: The mortality risks of all causes were increased among patients (n = 158 065) relative to comparison individuals (n = 3 161 300). Mortality rate differences were greater for natural causes, while relative risks (HRs) were higher for unnatural causes. Suicide was the leading cause of death within the first year of discharge, while circulatory and respiratory diseases were the leading causes of death from the second year. The mortality rates and HRs for all causes of death (except homicide) were highest during the first 3 months. The elevated risk of unnatural-cause mortality declined rapidly after discharge but remained high in the long term; in contrast, risk elevation for natural-cause mortality was more stable over time. Approximately one-eighth of patients (12.9%, 95% confidence interval 12.7-13.7%) died within 5 years of follow-up. CONCLUSIONS: Integrated physical and mental health care is needed to reduce excess mortality, particularly during the first 3 months post-discharge, among psychiatric patients.

Quetiapine is a common off-label antipsychotic drug for treating insomnia. Its effects in different disease conditions and dosages remain unclear. We conducted a systematic review and meta-analysis in clinical trials examining the efficacy of low-dose quetiapine in sleep. We obtained 21 clinical trials. Mean difference (MD), standard mean difference (SMD), and odds ratio (OR) were used to estimate the effect sizes using a random-effects model. The pooled results showed that quetiapine improved sleep quality compared with placebo (SMD: -0.57 [95%CI: -0.75, -0.4]). The SMD of sleep quality was correlated with age (coefficient: -0.0174) and sex (coefficient: -0.012). The significant effects were observed in the general anxiety disorder (SMD: -0.59 [95%CI: -0.92, -0.27]), major depressive disorder (SMD: -0.47 [95%CI: -0.66, -0.28]), and healthy (SMD: -1.33, [95%CI [-2.12, -0.54]) subgroups, at the dosage of 50 mg (SMD: -0.36 [95%CI: -0.36, -0.11]), 150 mg (SMD: -0.4 [95%CI: -0.52, -0.29]), and 300 mg (SMD: -0.17 [95%CI: -0.31,-0.04]). Quetiapine increased total sleep time compared with placebo (MD: 47.91 [95%CI: 28.06, 67.76]) but not when compared with other psychiatric drugs (MD: -4.19 [95%CI: -19.43, 11.05]). Adverse events (AEs) and discontinuation due to AEs were common among the quetiapine users. Quetiapine is effective as a sleep-helping drug. Precaution is suggested when interpreting the results on the elderly due to the high heterogeneity caused by incorporating patients over 66 years in the meta-analyses. We recommend an initial dosage of 50-150 mg/day with priority consideration for the elderly with GAD or MDD while monitoring its potential AEs.

OBJECTIVE: This study aimed to examine the characteristics of psychiatrists and the hospital settings in relation to the first-time diagnoses of anorexia nervosa (AN) and bulimia nervosa (BN) and depict medical utilization and the detection rate before diagnosis of patients with AN and BN. METHOD: We extracted data of individuals with AN or BN, as defined by the International Classification of Diseases, Ninth Revision, Clinical Modification, from a national health insurance database. Individuals with AN (n = 1,893) or BN (n = 10,542) who were first-time diagnosed by psychiatrists from 2002 to 2013 were included. Individuals with schizophrenia were selected as control groups that were matched with the incident AN and BN cases for sex, age stratum, and year of diagnosis. RESULTS: AN was more likely to be diagnosed by female psychiatrists. Patients with AN were more frequently diagnosed in medical centers while patients with BN were mostly diagnosed in primary care clinics. Nearly all patients with AN and BN had sought treatment for physical problems but less than half had sought help for mental health problems in the year preceding the diagnosis. Individuals with AN, BN, and schizophrenia were all under-detected by nonpsychiatric medical professionals. Notably, BN was least likely to be recognized by both psychiatrists and other medical professionals. DISCUSSION: Our findings underscore the importance of educational programs that are designed to improve the detection and management of eating disorders by medical professionals in Taiwan. Advanced educational programs that target differential diagnosis and the tailored management of different eating disorders should be highlighted among psychiatrists.

OBJECTIVE: This study aimed to examine the health service use and healthcare costs of adults with anorexia nervosa (AN) and bulimia nervosa (BN) in Taiwan. METHOD: AN and BN cases between 2002-2013 were extracted from a national health insurance database. For each AN and BN case, we randomly selected 10 controls with no eating disorder, matched for sex, age, urbanization of residence, and year of medical visit. The percentage and frequency of health services use and costs in the year preceding and after the diagnosis of AN/BN were compared between groups. We used generalized linear models with gamma distribution and log link function to determine the effects of age, sex, and psychiatric comorbidities on the total cost adjusting for physical comorbidities and to calculate the mean cost difference between groups by using marginal and incremental effects. RESULTS: Both individuals with AN and BN had significantly elevated healthcare utilization and costs compared to controls during the baseline and one-year period after diagnosis. Patients with AN had more than three times higher total costs (US $792) and patients with BN had two times higher total costs (US $320) than individuals without eating disorders. Comorbidity of depressive disorder and older age significantly increased healthcare costs among both individuals with AN and BN. DISCUSSION: There are high medical and economic burdens of care for individuals with AN and BN. Early diagnosis and integrated care for eating disorders are important tasks to reduce disease burden in Taiwan.

BACKGROUND: This study aimed to compare the predictors of suicides among psychiatric inpatients and recently discharged patients and to examine the association between the length of stay and suicides. METHODS: Data from psychiatric inpatients were extracted from the National Health Insurance databank and merged with information from the Cause of Death data using unique identification numbers. Poisson regression analyses were used to estimate the incidence rate ratio for inpatient and post-discharge suicides, which included the variables of sex, age, psychiatric diagnosis, and number of admissions in the preceding year. The associations between length of stay and inpatient and post-discharge suicide were examined using multivariate Poisson regression analyses that were adjusted for these variables. RESULTS: A diagnosis of affective disorders and a higher number of previous admissions increased both inpatient and post-discharge suicides. Patients older than 15-24 years had a significantly lower inpatient suicide risk but were more likely to die by suicide post-discharge. The risk of suicide both during the inpatient stay and post-discharge statistically significantly decreased when the length of stay was longer. LIMITATIONS: As there were variations in societal, environmental, and facility-level factors that might have influenced the association between length of stay and suicide, the generalization of our findings to different settings may be impeded. CONCLUSIONS: This study provides additional evidence that hospitalization helps to reduce the suicide risk. It suggests that medical professionals should be alert to inpatient suicide and that they should determine the optimal length of stay considering post-discharge suicide.

PURPOSE: In contrast to the downsizing trend of psychiatric beds in the Western world, the psychiatric bed capacity in Taiwan has steadily increased in recent decades. This study aimed to assess the suicide rates and their variations over time among psychiatric inpatients and recently discharged patients. METHODS: Data on psychiatric inpatients admitted from 2002 to 2013 were extracted from the psychiatric inpatient registry of the National Health Insurance and merged with information from the Cause of Death data by means of unique identified numbers. Suicides occurring during admission and within 90 days after discharge were defined as inpatient and postdischarge suicides, respectively. Calendar year was fitted as a continuous variable in multivariate Poisson regression models to evaluate these rates over time. The analyses were adjusted for sex, age, primary psychiatric diagnosis, and number of admissions in the preceding year. RESULTS: The overall inpatient suicide rate was very low (81 per 100,000 person-years). It decreased significantly from 146 to 74 per 100,000 person-years over the study period. This fall was observed among both genders and across all psychiatric diagnoses. The postdischarge suicide rate was comparatively high (1108 per 100,000 person-years) and did not show statistically significant change over the study period. CONCLUSIONS: Our results suggest that efforts to increase public awareness of mental disorders and efficient utilization of psychiatric inpatient care are essential for suicide prevention despite the comparatively high bed capacity. The discharge plans of inpatients should be bridged with population suicide prevention programs for continuity of care after discharge.

This exploratory study examined the cortisol awakening response (CAR) in patients with bipolar disorder (BPD) at acute phases and partial remission of manic or depressive episodes. Saliva samples of twenty-seven BPD inpatients and 25 healthy controls were collected to determine the CAR patterns, and 12 patients were sampled again at partial remission. BPD patients exhibited a non-enhanced CAR pattern. Lower cortisol expression and a blunted CAR distinguished bipolar-depressive patients from the controls. The intra-individual follow-up for both patient groups revealed a non-significant improvement in CAR patterns, indicating a trend of a normalized CAR after partial remission for BPD patients.

OBJECTIVE: This study examined the psychometric properties of the Internet and paper-and-pencil versions of the Mandarin Chinese version of the Night Eating Questionnaire (C-NEQ) and compared these measures' validity. METHOD: The C-NEQ was evaluated through two different media: 626 participants completed the C-NEQ on the Internet and 160 participants completed the paper-form C-NEQ at the psychiatric outpatient clinics. A subgroup completed both versions of the C-NEQ (n=50). The Night Eating Syndrome History and Inventory was used to identify individuals with night eating syndrome (NES). RESULTS: The paper-and-pencil and Internet versions of the C-NEQ both showed good internal consistency, reliability, and concurrent validity. Reliability between the Internet and the paper-and-pencil versions of the C-NEQ was excellent (ICC=.96). Diagnostic analysis of the C-NEQ's performance using the Receiver Operation Curve method showed excellent results in both versions; the area under the curve did not differ significantly between the versions. Regarding detecting NES, the Internet version had a higher optimal cutoff point than the paper-and-pencil version (23 and 22, respectively). CONCLUSIONS: The Internet and paper-and-pencil versions of the C-NEQ both showed strong reliability and validity; however the two versions appear to differ marginally regarding usage in NES detection.

BACKGROUND: To examine the differences of associated characteristics and prescription drug use between co-occurring unipolar and bipolar disorders in patients with eating disorders (EDs). METHODS: Patients with EDs and major depressive episode (MDE) were recruited from psychiatric outpatient clinics. They were interviewed and completed self-administered measures assessing eating and general psychopathology. The prescribed drugs at the index outpatient visit were recorded. Clinical characteristics and prescription drugs of groups with major depressive disorder (ED-MDD), MDE with lifetime mania (ED-BP I), and MDE with lifetime hypomania (ED-BP II) were compared. Continuous variables between groups were compared using generalized linear regression with adjustments of age, gender, and ED subtype for pair-wise comparisons. Multivariate logistic regression with adjustments of age, gender, and ED subtype was employed to estimate adjusted odds ratios with 95% confidence intervals between groups. RESULTS: Two hundred and twenty-seven patients with EDs had a current MDE. Among them, 17.2% and 24.2% experienced associated manic and hypomanic episodes, respectively. Bipolar I and II patients displayed significantly poorer weight regulation, more severe impulsivity and emotional lability, and higher rates of co-occurring alcohol use disorders than ED-MDD patients. ED-BP I patients were found to have the lowest IQ, poorest working memory, and the most severe depression, suicidality and functional impairment among all patients. Patients with ED-BP II shared affect and behavioral dysregulations with ED-BP I, but had less severe degrees of cognitive and functional impairments than ED-BP I. Patients with ED-BP I were significantly less likely than those in the ED-MDD and ED-BP II groups to be on antidepressant monotherapy, but a great rate (27%) of ED-BP I individuals taking antidepressant monotherapy had potential risk of mood switch during the course of treatment. CONCLUSIONS: Our study identified discriminative features of bipolar I and II disorders from MDD among a group of depressed ED patients. We suggest that the associated mania, hypomania, and mood lability are predictors of clinical severity and should be identified from ED patients presented with depressive features. Accurate diagnosis of bipolar disorders may have implications for pharmacotherapy in patients with EDs.

OBJECTIVE: An intertwined relationship has been found between dissociative and psychotic symptoms, as the two symptom clusters frequently co-occur, suggesting some shared risk factors. Using a source monitoring paradigm, previous studies have shown that patients with schizophrenia made more errors in source monitoring, suggesting that a weakened sense of individuality may be associated with psychotic symptoms. However, no studies have verified a relationship between sense of individuality and dissociation, and it is unclear whether an altered sense of individuality is a shared sociocognitive deficit underlying both dissociation and psychosis. METHOD: Data from 80 acute psychiatric patients with unspecified mental disorders were analyzed to test the hypothesis that an altered sense of individuality underlies dissociation and psychosis. Behavioral tasks, including tests of intelligence and source monitoring, as well as interview schedules and self-report measures of dissociative and psychotic symptoms, general psychopathology, and trauma history, were administered. RESULTS: Significant correlations of medium effect sizes indicated an association between errors attributing the source of self-generated items and positive psychotic symptoms and the absorption and amnesia measures of dissociation. The associations with dissociative measures remained significant after the effects of intelligence, general psychopathology, and trauma history were excluded. Moreover, the relationships between source misattribution and dissociative measures remained marginally significant and significant after controlling for positive and negative psychotic symptoms, respectively. LIMITATIONS: Self-reported measures were collected from a small sample, and most of the participants were receiving medications when tested, which may have influenced their cognitive performance. CONCLUSIONS: A tendency to misidentify the source of self-generated items characterized both dissociation and psychosis. An altered sense of individuality embedded in self-referential representations appears to be a common sociocognitive deficit of dissociation and psychosis.
RESUMO
Eating disorders (EDs) have been underdiagnosed in many clinical settings. This study investigates the influence of clinical characteristics on presenting symptoms of patients with EDs. Psychiatric outpatients, aged 18-45, were enrolled sequentially and received a two-phase survey for EDs in August 2010-January 2013. Their primary reasons for seeking psychiatric help were obtained at their first encounter with outpatient psychiatrists. Patients' clinical and demographic characteristics were compared according to presenting symptoms with or without eating/weight problems. Of 2140 patients, 348 (16.3%) were diagnosed with an ED (22.6% of women and 6.3% of men). The three most common reasons for seeking psychiatric help were eating/weight problems (46.0%), emotional problems (41.3%), and sleep disturbances (19.3%). The multivariate analyses suggest that when patients with EDs presented symptoms that were less related to eating/weight problems, they were significantly more likely to be those having diagnoses other than anorexia nervosa or bulimia nervosa and less severe degree of binge-eating. Further, patients with EDs who demonstrated more impulsive behaviors and poorer functioning were less likely to report their eating problems when visiting psychiatric clinics. Thus, ED should be assessed routinely in patients with complex psychopathology to facilitate comprehensive treatment.

Swift switching, along with atypical ability on updating and inhibition, has been found in non-clinical dissociators. However, whether swift switching is a cognitive endophenotype that intertwines with traumatisation and pathological dissociation remains unknown. Unspecified acute psychiatric patients were recruited to verify a hypothesis that pathological dissociation is associated with swift switching and traumatisation may explain this relationship. Behavioural measures of intellectual function and three executive functions including updating, switching and inhibition were administered, together with standardised scales to evaluate pathological dissociation and traumatisation. Our results showed superior control ability on switching and updating in inpatients who displayed more symptoms of pathological dissociation. When all three executive functions were entered as predictors, in addition to intellectual quotient and demographic variables to regress upon pathological dissociation, switching rather than updating remained the significant predictor. Importantly, the relationship between pathological dissociation and switching became non-significant when the effect of childhood trauma were controlled. The results support a trauma-related switching hypothesis which postulates swift switching as a cognitive endophenotype of pathological dissociation; traumatisation in childhood may explain the importance of swift switching.

BACKGROUND/PURPOSE: Although dancers are at risk for eating disorders (EDs), little is known about the features of EDs among the dance population. This study explores the prevalence of EDs, and their psychiatric comorbidities and correlates in dance students. METHODS: In total, 442 female high-school dance students participated in a two-phase survey. All participants completed screening questionnaires as well as measures assessing teasing, self-esteem, perfectionism, body dissatisfaction, and personality. Of the participating students, 311 underwent the Structured Clinical Interview for DSM-IV-TR Axis I Disorders. RESULTS: Sixty-eight individuals (15.4%) had an ED by DSM-IV diagnosis. The prevalence of any co-occurring mood (47.1%) and anxiety disorders (30.9%) was high. Although low self-esteem, high neuroticism, and high psychological distress were associated with EDs in univariate analysis, only teasing for overweight and body image dissatisfaction were significantly associated with EDs by multivariate analysis. CONCLUSION: Prevention and intervention programs for dance students should include recognition and management of emotional disorders and strategies promoting positive body image and reducing the incidence of negative weight-related comments.
