Context-dependent responses to the spread of COVID-19 among national and international students during the first lockdown:An online survey

Background: Restrictions to minimize social contact was necessary to prevent the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus but may have impacted individuals' mental well-being. Emotional responses are modulated by contextual information. Living abroad during the coronavirus disease 2019 (COVID-19) pandemic may have boosted the feeling of isolation as the context is unfamiliar. Objectives: This study compared the psychological impact of social distancing in national students (living in a familiar context) versus international students (living in an unfamiliar context). Methods: During March/April 2020 (first lockdown in the Netherlands), 850 university students completed an online survey. Structural equation modeling (SEM) was conducted to compare how students' responses to the virus were predicted by health anxiety, emotional distress, and personal traits. Results: Compared with national students, international students showed higher levels in 4 identified factors (COVID-19-related worry, perceived risk of infection, distance from possibly contaminated objects, distance from social situations). The factors were mainly predicted by health anxiety across international students, while emotional distress and individual traits (eg, intolerance of uncertainty) played a role across national students. Conclusions:In the familiar context, individual characteristics (traits) predicted the responses to the virus, while the unfamiliar context drove individuals' health-focused responses. Living in a foreign country is associated with psychological burdens and this should be considered by universities for more pronounced social support and clear references to health-related institutions.</p

Measuring and Modelling Exposure to External Workplace Aggression in Three Types of Emergency Responders.

The measurement properties of indices about workplace aggression initiated by the public, referred to as external workplace aggression, are underresearched. This study addressed how exposure to external workplace aggression is best measured and modeled in three types of emergency responders. The study inspected the factor structure and explored the addition of severity to an existing measure of frequency of exposure to workplace aggression, which addresses forms of physical aggression, threats, and verbal and nonverbal/nonphysical aggression (gestures) by people outside the organization directed toward employees. Self-reported data from 1,499 emergency responders, including emergency medical workers, firefighters, and police officers in the Netherlands, were analyzed using factor analyses in Mplus. In addition, the relationships between workplace aggression indices and a measure of the situational risk for violence were tested. Results show that the frequency index measured exposure to external workplace aggression better than the index combining the frequency and severity, and that factor structures of indices differed, regarding number and content of factors, between the three groups of emergency responders. An important implication is that researchers and policy employees can use a relatively simple measure to examine exposure to aggression in organizations

Coping and resilience in adults: a cross-sectional network analysis

Background and objectives: Coping and resilience, how we deal with problems and difficulties and recover from misfortune or change, are two well-known interrelated conce

No intolerance of errors:The effect of intolerance of uncertainty on performance monitoring revisited

Errors have been conceptualized as internal forms of threat that can cause harm in unpredictable ways. An index of error processing is the error-related negativity (ERN), an event-related potential reflecting variability in the sensitivity to errors. Prior work has shown the relationship between psychopathology symptoms and the ERN is unclear, and may be moderated by intolerance of uncertainty (IU), a trait that captures how people react to unpredictability. IU includes two subfactors of prospective IU (active seeking of predictability) and inhibitory IU (behavioral paralysis). In the present study, 188 undergraduates performed an Eriksen flanker task designed to elicit the ERN, while brain activity was recorded using electroencephalography (EEG). Participants completed the Intolerance of Uncertainty Scale, Short Form (IUS-12), and other measures of anxiety, depression and worry. Total IU explained 5 % of the variance in correct-response negativity (CRN), but was not associated with the ERN in our sample. In contrast to previous findings, the IU subfactors did not predict the ERN or post-error slowing (PES), nor did total IU and depression interact to predict the ERN. Exploratory analyses also showed that total IU did not moderate the relationship between trait anxiety and the ERN. Small samples may have previously exaggerated the links between self-reported IU and the ERN. As such, further high-powered replications are required to confirm if, and how, they are related

Impaired subjective self-control in alcohol use: An ecological momentary assessment study

Background: While both theory and empirical findings have supported impaired self-control as a crucial factor in understanding problem drinking, little is known about the relationship of self-control and drinking in naturalistic settings. The present study uses Ecological Momentary Assessment (EMA) to examine the predictive relationships between impaired subjective self-control, craving and alcohol use in everyday life. Methods: A sample of 172 regular drinkers responded on their smartphone to three random prompts each day for seven days in which amount of perceived self-control and craving were measured with self-report. In the meantime, participants were instructed to initiate an EMA report when they started drinking alcohol. Results: Findings supported the hypotheses that impaired self-control and higher craving levels were prospectively related to the likelihood that people will drink. That is, on random assessments that preceded drinking (i.e., were within two hours of drinking), perceived self-control was lower and craving was higher compared to random assessments that were not followed by drinking. Additionally, during drink consumption, impaired self-control and craving were associated with a higher amount of expected alcohol consumption. Findings further indicated that subjective self-control acted as a moderator of the relationship between craving and alcohol consumption during drinking occasions. Conclusions: By using a smartphone mobile application, this study showed that impaired subjective self-control and cravin

Validation of the Multicultural Personality Questionnaire Short Form (MPQ-SF) for use in the context of international education

The Multicultural Personality Questionnaire (MPQ) is one of the most widely used instruments for measuring individuals’ intercultural competences. The original version consists of 91 items, divided into five subscales, and has been shown to predict attitudes, behavior, and outcomes in a variety of intercultural contexts. Recently, a 40-item short form of the MPQ was developed (MPQ-SF), which may be particularly useful in settings in which time or survey space are limited, or where respondent drop-out is likely to occur. For example, the MPQ-SF would be a valuable tool for assessing longitudinal development of multicultural personality traits in training or educational settings. A prerequisite for such research is to establish measurement invariance of the MPQ-SF between different respondent groups, as well as across time points. Using a sample of students in an international university program (n = 519), the present study examines how the scales perform among male and female respondents, between students of Western and Non-Western background, and across two time points, five months apart. Based on our findings, we conclude that all five subscales of the MPQ-SF display sufficient measurement invariance to be reliably used in this and similar contexts, in comparative as well as longitudinal study designs

No effect of repetitive tDCS on daily smoking behaviour in light smokers: A placebo controlled EMA study

Introduction The effectiveness of repetitive transcranial Direct Current Stimulation (tDCS) on reducing smoking behaviour has been studied with mixed results. Smoking behaviour is influenced by affect and context, therefore we choose to use mobile ecological momentary assessments (EMA) to measure changes in smoking behaviour after tDCS. Methods In a randomized, placebo-controlled, between subject study, we applied tDCS bilaterally with the anodal electrode targeting the right DLPFC (https://clinicaltrials.gov/ct2/show/NCT03027687). Smokers were allocated to six sessions of either active tDCS (n = 35) or sham tDCS (n = 36) and received two sessions on three different days in one week. They were asked to keep track of their daily cigarette consumption, craving and affect in an application on their mobile phones for three months starting one week before the first tDCS session. Results Number of smoked cigarettes a day p

Model method drawing acts as a double-edged sword for solving inconsistent word problems

Drawing bar diagrams has been shown to improve performance on mathematical word problems wherein the relational keyword is consistent with the required arithmetic operation. This study extends this by testing the effectiveness of bar diagram drawing for word problems with an inconsistent keyword-arithmetic operation mapping. Seventy-five fifth graders solved consistent and inconsistent word problems while encouraged to draw bar diagrams. For each word problem, we assessed problem type (consistent/inconsistent), performance (correct/incorrect), and bar diagrams (accurate/inaccurate/no drawing). Overall, bar diagram drawing was associated with increased performance on both consistent and inconsistent word problems, but the strongest benefits of drawing were found for inconsistent word problems. For inconsistent word problems, bar diagram accuracy was more clearly related to performance (accurate bar diagrams related to correct answers, but inaccurate ones to incorrect answers) than for consistent word problems. We conclude that bar diagram drawing provides an effective graphical support for solving inconsistent word problems
