Abstract. The current study aims to explore the likelihood of there being a higher-order factorial model of the Brief COPE ( Carver, 1997 ) that is equally appropriate and valid for different traumatic groups (i.e., breast cancer patients and female flood survivors) at 3–4 months after the traumatic event. Both groups of participants include 180 survivors. Five factorial models for the Brief COPE were identified when reviewing the literature, and model comparisons were made by conducting confirmatory factor analyses (CFAs). The three dimensions of the Brief COPE posited by Litman (2006) and Gutiérrez, Peri, Torres, Caseras, and Valdés (2007) , namely self-sufficient coping, socially-supported coping, and avoidant coping, were supported in both traumatic populations. Tests of measurement invariance generally supported invariance (factor form, factor loadings, item intercepts, error variances, factor variances, and covariances) across groups, implying that groups perceive the latent factors in the same way and the higher-order coping across different traumatic groups is meaningful. Moreover, the relationship between the three higher-order coping factors and variables of psychological adjustment was examined. Generally, different relationships between the subtypes of coping and the outcomes of adaptation existed between female flood survivors and breast cancer patients. Further theoretical and practical implications for these relationships are discussed.

The emergence of Coronavirus disease 2019 (COVID-19) had rapidly spread since FEB/MAR 2020. Policy to prevent transmission of COVDI-19 resulted in multi-dimensional impact on social interaction. We aimed to develop a beneficial survey tool with favorable quality and availability, the Societal Influences Survey Questionnaire (SISQ), to evaluate social influences on people during this pandemic. The SISQ was developed with 15 items and 4-point Likert scales consisting of five factors. These include social distance, social anxiety, social desirability, social information, and social adaptation. Construct validity and reliability were performed to verify the SISQ. A total of 1912 Taiwanese were recruited. The results demonstrated that the SISQ has acceptable reliability, with Cronbach’s alphas ranging between 0.57 and 0.76. The SISQ accounted for 58.86% and satisfied the requirement of Kaiser–Mayer–Olkinvalues (0.78) and significant Bartlett’s Test of sphericity. Moreover, the confirmatory factor analysis fit indices also indicated the adequacy of the model. As for multiple comparison, females scored higher than males in factor of social distance. Unemployed participants and those without partners scored higher in several domains of factors. The survey method and survey instrument prove reliable and valuable, also providing different categories of assessment results regarding social influences and their impacts. Further studies are warranted to extend the applicability of SISQ.

ObjectiveTo 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.MethodsA 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.ResultsThe 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.ConclusionWhile 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.

Sarcophyton glaucum is one of the most abundant and chemically studied soft corals with over 100 natural products reported in the literature, primarily cembrane diterpenoids. Yet, wide variation in the chemistry observed from S. glaucum over the past 50 years has led to its reputation as a capricious producer of bioactive metabolites. Recent molecular phylogenetic analysis revealed that S. glaucum is not a single species but a complex of at least seven genetically distinct species not distinguishable using traditional taxonomic criteria. We hypothesized that perceived intraspecific chemical variation observed in S. glaucum was actually due to differences between cryptic species (interspecific variation). To test this hypothesis, we collected Sarcophyton samples in Palau, performed molecular phylogenetic analysis, and prepared chemical profiles of sample extracts using gas chromatography-flame ionization detection. Both unsupervised (principal component analysis) and supervised (linear discriminant analysis) statistical analyses of these profiles revealed a strong relationship between cryptic species membership and chemical profiles. Liquid chromatography with tandem mass spectrometry-based analysis using feature-based molecular networking permitted identification of the chemical drivers of this difference between clades, including cembranoid diterpenes (2R,11R,12R)-isosarcophytoxide (5), (2S,11R,12R)-isosarcophytoxide (6), and isosarcophine (7). Our results suggest that early chemical studies of Sarcophyton may have unknowingly conflated different cryptic species of S. glaucum, leading to apparently idiosyncratic chemical variation.

This study designed a system for evaluating personal stress by assessing activities of autonomic nervous system (ANS) using heart rate variability (HRV) analysis through Photoplethysmography (PPG) signal. To investigate the performance of stress relaxation, this study also designed an environment with personal preferences. The environment included visional, audio and olfactory elements. Five healthy college students were invited to five days stress task study. The personal preferences of environment were set before experimental procedure. The subjects were required to fill the State-Trait Anxiety Inventory (STAI), and PPG signal was acquired by the developed system during experimental procedure. The experimental procedure was composed with a sequence of initial rest for baseline, relaxation environment after rest, stress task and relaxation environment after stress task. Results indicated that a decrease in STAI and LF/HF was obtained during relaxation environment, whereas increase in STAI and LF/HF was obtained during stress task. These results suggested that an environment with personal preferences may improve helpfully for stress relaxation.

Objective The frequency of various disasters has become a 21st century global crisis. The biological-disaster of the coronavirus disease of 2019 (COVID-19) gave rise to a multi-dimensional global impact. The 25 items of Societal Influences Survey Questionnaire (SISQ) was developed to assess various categories of social influence during the pandemic. This study compares the SISQ scores of Taiwan, Republic of Korea (Korea) and Japan.Methods Persons living in Korea, Japan, and Taiwan were recruited and evaluated through an SISQ online survey. The SISQ is composed of 25 items each with a 4-point Likert scale. The SISQ assesses the following six factors: self-restraint, social impact, government policy, social cost, concern of infection, and awareness of information. A principal factor analysis and reliability (Cronbach’s alpha) were performed to validate the SISQ. The analysis of variance (ANOVA) and post-hoc analysis was conducted to explore the differences between groups.Results The SISQ had acceptable reliabilities, and accounted for 58.86% of the variance. The significance for ANOVA with post-hoc analysis showed that scores of self-restraints ranked highest in Japan followed by Taiwan and Korea. Taiwanese scored lower than other nations regarding the concern of infection. Koreans scored higher in awareness of information than the other two nations. The effect of age and marital status were also estimated.Conclusion The SISQ comprehensively evaluate multiple domains of social influence, and it manifests the divergence of social impacts across the three nations.
