Understanding the mental health impacts of biological disasters: Lessons from Taiwan's experience with COVID-19.

Biological disasters pose a growing challenge in the 21st century, significantly impacting global society. Taiwan has experienced such disasters, resulting in long-term consequences like loss of life, trauma, economic decline, and societal disruptions. Post-disaster, mental health issues such as fear, anxiety, depression, post-traumatic stress disorder (PTSD), and stress surge, accompanied by increased suicide rates. The Coronavirus disease 2019 (COVID-19) (also called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) pandemic, recognized as a biological disaster, triggered lockdowns and quarantines in Taiwan, causing lifestyle changes, economic recession, and so on. These shifts may elevate uncertainty about the future, intensifying mental stress and leading to a rise in various mental illnesses. This article reviews mental health studies conducted in Taiwan during the pandemic, emphasizing the need to integrate this research for future preparedness and interventions regarding the mental health impacts of biological disasters, including COVID-19. Further research is essential to explore long-term effects, interventions, and generalizability.

A Community Survey of Quality of Life and Psychiatric Disorders among Residents Following the Kaohsiung Gas Explosion: a 5-Year Cross-Sectional Follow-Up Study.

To investigate factors associated with quality of life (QoL) and disaster-related psychiatric disorders, including posttraumatic stress disorder (PTSD) and major depressive episode (MDE), in the survivors of a gas explosion in Taiwan 5 years after the event. A community-based cross-sectional study of residents from an area that experienced a gas explosion was conducted 5 years after the event. The Short Form 12v2 (SF-12v2) was used to screen 2511 participants. The Disaster-Related Psychological Screening Test (DRPST) was used to assess probable MDE and PTSD. A total of 2511 participants, including 604 males and 1907 females, completed the QoL survey. The average age was 56.02 ± 16.78 years, and most participants were in the ≧65 age group (39.7%). The males had better QoL in the physical dimensions. Lifestyle was significantly positively associated with QoL. A total of 894 participants completed the DRPST, which showed some individuals with probable MDE (n = 93, 10.4%), probable PTSD (n = 22, 2.5%), or probable MDE and PTSD (n = 49, 5.5%); most people had no MDE or PTSD (n = 730, 81.7%). Those in the probable PTSD or MDE groups were significantly more likely to be female or to be experiencing stressors (p < 0.001). The participants continued to be affected by the disaster based on their QoL, even 5 years later. Females had a higher risk of probable psychiatric disorders and poorer QoL in the physical dimensions. Long-term follow-up, interventions and investigations after a disaster are needed.

Rate of psychiatric disorders and associations with quality of life among community members following the Kaohsiung gas explosion: an 18-month cross-sectional follow-up study.

OBJECTIVE: To conduct a follow-up on the rate and related risk factors of probable disaster-related psychiatric disorders such as depressive disorder (major depressive episode, MDE), stress disorders, post-traumatic (posttraumatic stress disorder, PTSD), and the quality of life of the survivors of a fossil gas explosion in Taiwan 18 months after the event. METHODS: A community-based survey of residents of a community that experienced a petrochemical gas explosion with cross-sectional assessments was conducted 18 months after the event. Two screening tools, including the Disaster-Related Psychological Screening Test (DRPST) and Short Form 12v2 (SF-12v2), were used to survey a representative sample of 388 participants. RESULTS: The average age of 388 participants is 43.27 ± 15.98 years (males: 203, average age: 41.44 ± 15.74 years; females: 185; average age: 45.27 ± 16.03 years). Probable PTSD, probable MDE, probable PTSD and MDE, and non-PTSD or non-MDE (non-P or -M) were present in 34 (8.8%), 14 (3.6%), 9 (2.3%), and 331 (85.3%) participants, respectively. The significant associated factor for probable PTSD or MDE among those who experienced disaster was financial problems. The associated factors on different quality of life subscales were old age, physical injury, employment, educational level, financial problems, probable PTSD and probable MDE. CONCLUSION: While participants' psychiatric status improved after 18 months, their quality of life continued to be affected, especially the quality of life of those with probable PTSD combined with MDE. Postdisaster treatment and follow-up should be addressed to a greater degree, especially for victims with mental illness, physical injuries and financial problems.

Intraprocedural Parenchymal Blood Volume Is a Predictor of Treatment Response for Chemoembolization in Hepatocellular Carcinoma: Results of a Prospective Study.

PURPOSE: To evaluate cone-beam parenchymal blood volume (PBV) before and after embolization as a predictor of radiographic response to transarterial chemoembolization in unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS: A phase IIa prospective clinical trial was conducted in patients with HCCs > 1.5 cm undergoing chemoembolization; 52 tumors in 40 patients with Barcelona Clinic Liver Criteria stage B disease met inclusion criteria. Pre- and postembolization PBV analysis was performed with a semiquantitative best-fit methodology for index tumors, with a predefined primary endpoint of radiographic response at 3 months. Analyses were conducted with Wilcoxon signed-rank tests and one-way analysis of variance on ranks. RESULTS: Mean tumoral PBV measurements before and after embolization were 170 mL/1,000 mL ± 120 and 0 mL/100 mL ± 130, respectively. Per modified Response Evaluation Criteria In Solid Tumors, 25 tumors (48%) exhibited complete response (CR), 13 (25%) partial response (PR), 3 (6%) stable disease (SD), and 11 (21%) progressive disease (PD). Statistically significant changes in median PBV (ΔPBV) were identified in the CR (P = .001) and PR (P = .003) groups, with no significant difference observed in SD (P = .30) and PD groups (P = .06). A statistically significant correlation between ΔPBV and tumor response was established by one-way analysis of variance on ranks (P = .036; CR, 200 mL/100 mL ± 99; PR, 240 mL/100 mL ± 370; SD, 64 mL/100 mL ± 99; PD, 88 mL/100 mL ± 129). CONCLUSIONS: Intraprocedural PBV can be used as a predictor of response in index HCC tumors of > 1.5 cm.

A preliminary report on psychiatric impairments and quality of life among Kaohsiung gas explosion victims 6 months after the event.

OBJECTIVE: To investigate the prevalence and related risk factors for probable disaster-related psychiatric disorders, such as major depressive episodes (MDEs) and posttraumatic stress disorder (PTSD), among the victims of a petrochemical gas explosion in Kaohsiung, Taiwan, 6 months after the event. Additionally, the quality of life (QOL) of victims with related risk factors was simultaneously investigated. METHODS: A community-based screening survey with cross-sectional assessments was conducted. The victims of a petrochemical gas explosion were surveyed 6 months after the event. We used two scales, the Disaster-Related Psychological Screening Test and Short Form 12v2, to survey a representative sample of 502 participants (average age: 42.90 ± 16.61 years; M: 270, average age: 40.89 ± 16.40 years; F: 232; average age: 45.25 ± 16.58 years). The Chinese version of SPSS 17.0 software was used to perform the analysis. RESULTS: Non-PTSD or non-MDE (non-P or M), probable PTSD, probable MDE and probable PTSD, and MDE were present in 341 (67.9%), 54 (10.8%), 37 (7.4%) and 70 (13.9%) participants, respectively. QOL worsened (negative trend) among the groups in the following order: non-P or M, probable PTSD or MDE alone, and probable PTSD and MDE. The risk factors for probable PTSD or MDE were female gender, older age, physical injury, significant financial loss, and lack of religious belief. The risk factors for poorer QOL subscales were older age, financial problems, physical injury, higher educational level, religious beliefs, and probable PTSD and/or MDE. CONCLUSION: This study shows that probable PTSD/MDE is associated with lower QOL, supporting the need for early mental health rehabilitation after a disaster. Therefore, rapid screening and early mental rehabilitation are very important.

State of the ablation nation: a review of ablative therapies for cure in the treatment of hepatocellular carcinoma.

Primary liver cancer, mainly hepatocellular carcinoma, is one of the most common malignancies worldwide. Surgical management, either resection or transplantation, is considered definitive treatment, however, less than 20% of patients are ultimately candidates. Thermal ablation modalities such as radiofrequency ablation and microwave ablation have evolved such that these modalities have been applied with curative intent. Moreover, thermal ablation has demonstrated efficacy in treating early-stage tumors and can be offered as first-line treatment in patients with uncomplicated disease. Attributing to refinements in technology and techniques, recent studies evaluating stereotactic ablative body radiotherapy have shown promising results, while irreversible electroporation, an emerging modality, may further expand the role of ablative therapy in treating potentially resectable hepatocellular carcinoma.

A Cross Cultural Comparison of Attitude of Mental Healthcare Professionals Towards Involuntary Treatment Orders.

The purpose of this study was to investigate East-West cultural attitudes of mental healthcare professionals (MHPs) towards Involuntary Treatment Orders (ITOs) among Taiwan, England, Wales, and New Zealand. Data on Taiwanese MHPs' views of ITO regime were collected from the National Psychiatric Disease Mandatory Assessment and Community Care Review Committee (N = 176). A national survey instrument was designed to assess the level of support for ITOs among senior clinicians and to determine their views on the importance of various factors in decision-making, the mechanisms through which coercion may work, impediments to its use, and its perceived impact on patients and therapeutic relationships. A descriptive analysis was carried out with data presented as appropriate for the distribution and a t-test was used to detect any differences by respondents. Risk reduction was ranked the most important factor in use of ITOs and reasons for discharging an order. Female respondents had higher approval ratings, with 85 % of agreeing that ITOs were of benefit to the therapeutic relationship, assured long-term stability, and increased medication compliance. The results suggest that clinicians decide the use of ITOs largely based on the risk management, both in terms of starting and ending an order. However, the use of ITOs vary which reflected in the practice. Given this variation in the use of enabling legislation, multidisciplinary input in decision-making is an essential safety mechanism.

Pooled Nucleic Acid Amplification Test for Screening of Stool Specimens for Shiga Toxin-Producing Escherichia coli.

Shiga toxin-producing Escherichia coli (STEC)-associated enteric illness is attributed to O157 and non-O157 serotypes; however, traditional culture-based methods underdetect non-O157 STEC. Labor and cost of consumables are major barriers to implementation of the CDC recommendation to test all stools for both O157 and non-O157 serotypes. We evaluated the feasibility of a pooled nucleic acid amplification test (NAAT) as an approach for screening stool specimens for STEC. For retrospective evaluation, 300 stool specimens were used to create pools of 10 samples each. The sensitivity was 83% for the preenrichment pooling strategy and 100% for the postenrichment pooling strategy compared with those for individual NAAT results. The difference in cycle threshold (CT) between individual and pooled NAAT results for specimens was significantly lower and more consistent for postenrichment pooling (stx1 mean = 3.90, stx2 mean = 4.28) than those for preenrichment pooling (excluding undetected specimens; stx1 mean = 9.34, stx2 mean = 8.96) (P ≤ 0.0013). Cost of consumables and labor time savings of 48 to 81% and 6 to 66%, respectively, were estimated for the testing of 90 specimens by the postenrichment pooled NAAT strategy on the basis of an expected 1 to 2% positivity rate. A 30-day prospective head-to-head clinical trial involving 512 specimens confirmed the sensitivity and labor savings associated with the postenrichment pooled NAAT strategy. The postenrichment pooled NAAT strategy described here is suitable for efficient large-scale surveillance of all STEC serotypes. Comprehensive detection of STEC will result in accurate estimation of STEC burden and, consequently, appropriate public health interventions.

Cancer in patients with schizophrenia: What is the next step?

People with schizophrenia, who constitute approximately 0.3-1% of the general population, have a nearly 20% shorter life expectancy than the general population. The incidence of varied types of cancers in patients with schizophrenia is controversial. The majority of previous research has demonstrated that patients who have schizophrenia and cancer have early mortality compared to the general population with cancer. The causes of early mortality in patients with schizophrenia and cancer might be attributed to a lower cancer screening rate and lack of effective treatment, including: (i) patient factors, such as poor lifestyle, passive attitude toward treatment, or comorbidity; (ii) physician factors, such as physician bias, which may decrease the delivery of care for individuals with mental disorders; and (iii) hospital administration factors, such as stigma and discrimination. Additional studies on patients with schizophrenia and cancer are warranted and should include the following: a comprehensive review of previous studies; a focus on differentiating the specific types of cancer; and methods for improvement. To decrease the early mortality of patients with schizophrenia, the following measures are proposed: (i) enhance early detection and early treatment, such as increasing the cancer screening rate for patients with schizophrenia; (ii) provide effective, timely treatment and rehabilitation; (iii) improve patients' psychiatric symptoms and cognitive impairment; (iv) promote healthy behavior in the general population and emphasize healthy lifestyles in vulnerable populations; and (v) remove the stigma of schizophrenia. To reduce disparities in physical health, public health strategies and welfare policies must continue to focus on this group of patients.

Work-related frustration among senior nurses at a medical centre.

AIMS AND OBJECTIVES: To investigate the levels and causes of work-related frustration among senior nurses. BACKGROUND: Role changes and the associated expectations and setbacks faced by senior middle-aged nurses can easily result in low morale. Therefore, working setbacks experienced by senior nurses must be investigated. DESIGN: A cross-sectional questionnaire study. METHODS: Purposive sampling was used to select questionnaire recipients. In total, 482 senior nurses completed and returned a structured questionnaire. RESULTS: The predictive factors for frustration at work among senior nurses included age, service unit, and the impact of sleep disorders, which jointly explained 54% of the variance. In particular, age and service unit were important predictive factors for frustration at work. CONCLUSIONS: Senior nurses had medium-to-low scores for frustration at work and did not perceive a high level of frustration. RELEVANCE TO CLINICAL PRACTICE: The outpatient departments and other medical departments in this sector should provide a reasonable system of incentives and promotion opportunities if they are to retain their most senior and experienced nurses. The results of this study could serve as a reference for hospital administrations.

[The Mental Rehabilitation of Burn Patients After a Major Disaster].

Many catastrophic disasters have happened in Taiwan over the last decade. As disaster is not a special occurrence but rather a part of the norm, mental rehabilitation should be treated as a mainstream issue in psychiatry. The internalization of emergency psychological interventions is necessary for every mental-health professional. The two primary categories of major manmade disasters in Taiwan over the past decade have been gas explosions and powder burns. Both categories have led to the serious injury of many individuals. The physical deformities and job problems faced by burn patients affect their psychiatric and emotional states both directly and indirectly. The psychiatric comorbidities of burn patients include: major depression, generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD), with GAD and PTSD comprising the most significant comorbidities in terms of numbers of diagnoses. To reduce psychological problems in the future, mental-health professionals should use appropriate psychological first aid (PFA) interventions in the early stages of treatment and rehabilitation. Mental rehabilitation is a major and comprehensive rehabilitation process. Mental-health professionals should thus use PFA to treat burn patients as well as provide long-term mental rehabilitation after discharge.

Effects of Home Visit Intervention on Re-hospitalization Rates in Psychiatric Patients.

To examine the home visit intervention (HoVI) effects on the re-hospitalization rate and medical costs in patients with schizophrenia or other psychiatric disorders. The subjects who received more than 3 HoVIs were defined as the HoVI group, whereas the subjects who received equal to or less than 3 HoVIs were defined as the HoVI < 4 group; the subjects who had never received an HoVI were defined as the non-HoVI group. Differences in the re-hospitalization rates and National Health Insurance (NHI) costs among the three groups were examined. The re-hospitalization rate of the HoVI group was significantly lower than that of the non-HoVI group. The hospitalization days and the NHI costs of the HoVI group were also lower than those of the non-HoVI group. However, the HoVI < 4 group was not different than the non-HoVI group regarding the re-hospitalization rate or the hospitalization days. The re-hospitalization rate was significantly higher before compared with after the HoVIs. The NHI costs were significantly higher before compared with after the HoVIs. HoVIs (More than 3 HoVIs) produced a lower re-hospitalization rate, number of hospitalization days, and NHI costs in patients who received care through the Home Visit. Project to strengthen the Community Rehabilitation Program.

Long-acting injectables and risk for rehospitalization among patients with schizophrenia in the home care program in Taiwan.

We aimed at evaluating the relationship between medication and treatment effectiveness in a home care setting among patients with schizophrenia. Patients with schizophrenia hospitalized between 2004 and 2009 with a primary International Classification of Diseases, Ninth Revision, Clinical Modification code of 295 were identified from Psychiatric Inpatient Medical Claims Data released by the National Health Research Institute in Taiwan. Patients who joined the home care program after discharge and were prescribed long-acting injection (LAI) (the LAI group) or oral antipsychotic medications (the oral group) were included as study subjects. The final sample for the study included 810 participants in the LAI group and 945 in the oral group. Logistic regression was performed to examine the independent effect of LAI medication on the risk for rehospitalization within the 12-month observation window after controlling for patient and hospital characteristics and propensity score quintile adjustment. The unadjusted odds ratio for rehospitalization risk was 0.80 (confidence interval, 0.65-0.98) for the LAI group compared to the oral group. The adjusted odds ratio was further reduced to 0.78 (confidence interval, 0.63-0.97). Results remained unchanged when the propensity score quintiles were entered into the regression for further adjustment. In a home care setting, patients treated with long-acting antipsychotic agents are at a significantly lower risk for psychiatric rehospitalization than those treated with oral medication. Consequently, LAI home-based treatment for the prevention of schizophrenia relapse may lead to substantial clinical and economic benefits.

Is low individual socioeconomic status (SES) in high-SES areas the same as low individual SES in low-SES areas: a 10-year follow-up schizophrenia study.

OBJECTIVE: This study investigates the relationship between individual and neighborhood socioeconomic status (SES) and mortality among patients with schizophrenia. METHODS: A study population was identified from the National Health Insurance Research Database (NHIRD) prior to the end of 1999 that included 60,402 patients with schizophrenia. Each patient was tracked until death or to the end of 2009. Individual SESs were defined by enrollee category. Neighborhood SES was defined by enrollee category (as a proxy for occupation) and education, which were classified according to the conventions of Hollingshead. Neighborhoods were also grouped into advantaged and disadvantaged areas. The Cox proportional hazards model was used to compare the death-free survival rate between the different SES groups after adjusting for possible confounding factors and risk factors. RESULTS: During the 10-year follow-up period, the mortality rates among high, moderate, and low individual SES groups were 12.22, 14.75, and 18.48%, respectively (P < 0.001). Schizophrenia patients with low individual SESs in disadvantaged neighborhoods had a risk of death that was 18-22% higher than that of those with high individual SES in advantaged neighborhoods. The analysis of the combined effect of individual SES and neighborhood SES revealed that the death rates were highest among those with low individual SES and low neighborhood SES (P < 0.001). CONCLUSIONS: Schizophrenia patients with low individual SES in disadvantaged neighborhoods have the highest risk of mortality despite a universal health-care system. Public health strategies and welfare policies must continue to focus on this vulnerable group.

Assessment of birth cohort screening of chronic hepatitis C in colorectal cancer screening patients in British Columbia.

Background: Since 2018, British Columbia (BC) has recommended chronic hepatitis C (HCV) screening for those born between 1945 and 1964, with a provincial prevalence of 2.31%. Combining HCV and colorectal cancer (CRC) screening can facilitate specialist referrals and follow-up. We assessed HCV screening uptake among CRC screening patients following the release of BC's birth cohort guidelines and examined the COVID-19 pandemic's impact on HCV screening practices. Methods: A retrospective review was conducted on patients referred to Vancouver Coastal Health Authority's CRC screening program. Two groups, Cohort A (October-December 2019) and Cohort B (December 2021), were studied to identify pandemic-related changes. Data on demographics, liver disease history, hepatitis B or HIV co-infection rates, and initial anti-hepatitis C and ribonucleic acid (RNA) testing dates were collected. Statistical analyses were performed with Stata 15.1. Results: A total of 579 patients were referred for the CRC screening program, of whom 465 were born between 1945 and 1964 and were included in the study. Among the 348 patients in cohort A, 144 (41%, 95% CI 36%-47%) were screened for HCV infection. Of these, four (1.2%) were positive for anti-hepatitis C, and one patient had positive RNA levels. Similar proportions of screenings were observed in cohort B (47.8%, 95% CI 39%-57%). Of those with liver disease, 66% had been screened for HCV. Conclusion: Birth cohort screening for HCV has been underutilized in British Columbia. Combining HCV and CRC screening could provide a practical approach to linking patients to health care.

The clinical effectiveness of elexacaftor/tezacaftor/ivacaftor (ETI) for people with CF without a F508del variant: A systematic review and meta-analysis.

BACKGROUND: Access to elexacaftor/tezacaftor/ivacaftor (ETI) for people with cystic fibrosis (PwCF) without a F508del variant is limited due to lack of clinical data supporting efficacy. METHODS: In this systematic review and meta-analysis, we examined patient-level data from studies reporting the clinical response to ETI for PwCF with non-F508del CFTR variants. We searched electronic data sources including Embase, MEDLINE, and CENTRAL from January 1st, 2019 to May 14th, 2024. FINDINGS: Our search results identified 4,795 studies and 20 met the eligibility criteria. 120 of 164 (73 %) individuals had a positive clinical response to ETI, defined by a sweat chloride (SwCl) decrease of ≥10 mmol/L or percent-predicted FEV1 (ppFEV1) improvement of ≥5 %. 51 unique ETI-responsive variants were represented across these 120 individuals and 27 of these variants (53 %) have not been previously approved by the U.S. FDA. For variants with at least 10 individuals treated with ETI to date, a consistent positive clinical response was observed for N1303K and G85E. For N1303K (n = 48), the median increase in ppFEV1 was 16 % (IQR: 8 %, 29 %), with a median decrease in SwCl of -9 (IQR: -4, -22) mmol/L. For G85E (n = 16), the median increase in ppFEV1 was 13.5 % (IQR: 8 %, 19 %) with a median decrease in SwCl of -46 (IQR: -39, -66) mmol/L. CONCLUSION: Additional ETI-responsive variants were identified following a comprehensive review of ETI clinical use in PwCF without F508del. This data can be used by the CF community in efforts to expand the labelled indications or to help advocate for off-label ETI reimbursement.

Characteristics of sleep disturbance across two waves of the COVID-19 pandemic among nursing staffs.

Objectives: COVID-19 has impacted human lifestyles, including sleep quality. For nursing staff, sleep disorders not only impact their health and daily lives but also have implications for patient safety. The objective of this study is to explore the impact of the COVID-19 pandemic on the psychological and social aspects of nursing staff and the factors influencing their sleep quality through a two-wave survey. Methods: Nursing staff from a psychiatric hospital in southern Taiwan were recruited in two waves during the COVID-19 epidemic. The level of sleep disturbance and related variables, such as Lo's Healthy and Happy Lifestyle Scale (LHHLS) and Societal Influences Survey Questionnaire (SISQ), were collected through self-report questionnaires. Factors related to the level of sleep disturbance were examined using univariate linear regression and multilevel linear regression. Results: 508 nursing staff members were included in the study, with 254 members in each wave. A significant difference was found between the two waves in the positive thinking of LHHLS and all subscales of SISQ. During the second wave, sleep disturbances were mainly related to self-efficacy, positive thinking, social anxiety, and social desirability. At the fourth wave, sleep disturbances were mainly related to self-efficacy, positive thinking, and social anxiety. However, these effects change when the trend of the epidemic shifts, and other factors are taken into account. Conclusions: This study analyzed the factors related to the sleep quality of nursing staff during the COVID-19 pandemic. We preliminarily explored the impact of the COVID-19 pandemic on the sleep quality of nursing staff. However, determining whether the end of the epidemic has reduced the impact on nursing staff requires further research.

Characteristics of Sleep Disturbance and Comparison Across Three Waves of the COVID-19 Pandemic Among Healthcare Workers.

OBJECTIVE: Healthcare workers (HCWs) suffered from a heavy mental health burden during the coronavirus disease-2019 (COVID-19) pandemic. We aimed to explore the differences in sleep disturbance in three waves of the COVID-19 pandemic in Taiwan among HCWs. Moreover, factors associated with sleep disturbances in the third wave were investigated. METHODS: This study, with three waves of cross-sectional surveys, recruited first-line and second-line HCWs. The level of sleep disturbance and related demographic variables were collected through self-report questionnaires. Differences in sleep disturbance across the three waves were compared with analysis of variance. Factors associated with the level of sleep disturbance were identified using univariate linear regression and further used for multivariate stepwise and bootstrap linear regression to identify the independent predictors. RESULTS: In total, 711, 560, and 747 HCWs were included in the first, second, and third waves, respectively. For first-line HCWs, sleep disturbance was significantly higher in the third wave than in the first wave. The level of sleep disturbance gradually increased across the three waves for all HCWs. In addition, sleep disturbance was associated with depression, posttraumatic stress disorder (PTSD) symptoms, anxiety about COVID-19, vaccine mistrust, and poorer physical and mental health among first-line HCWs. Among second-line HCWs, sleep disturbance was associated with younger age, depression, PTSD symptoms, lower preference for natural immunity, and poorer physical health. CONCLUSION: The current study identified an increase in sleep disturbance and several predictors among HCWs. Further investigation is warranted to extend the application and generalizability of the current study.

Development of a Rasch-calibrated emotion recognition video test for patients with schizophrenia.

Patients with schizophrenia tend to have deficits in emotion recognition (ER) that affect their social function. However, the commonly-used ER measures appear incomprehensive, unreliable and invalid, making it difficult to comprehensively evaluate ER. The purposes of this study were to develop the Computerized Emotion Recognition Video Test (CERVT) evaluating ER ability in patients with schizophrenia. This study was divided into two phases. First, we selected candidate CERVT items/videos of 8 basic emotion domains from a published database. Second, we validated the selected CERVT items using Rasch analysis. Finally, the 269 patients and 177 healthy adults were recruited to ensure the participants had diverse abilities. After the removal of 21 misfit (infit or outfit mean square > 1.4) items and adjustment of the item difficulties of the 26 items with severe differential item functioning, the remaining 217 items were finalized as the CERVT items. All the CERVT items showed good model fits with small eigenvalues (≤ 2) based on the residual-based principal components analysis for each domain, supporting the unidimensionality of these items. The 8 domains of the CERVT had good to excellent reliabilities (average Rasch reliabilities = 0.84-0.93). The CERVT contains items of the 8 basic emotions with individualized scores. Moreover, the CERVT showed acceptable reliability and validity, and the scores were not affected by examinees' gender. Thus, the CERVT has the potential to provide a comprehensive, reliable, valid, and gender-unbiased assessment of ER for patients with schizophrenia.
