Smoking related to anxiety and depression in Greek medical staff

We assessed the relation of anxiety and depression to smoking behavior in a sample of 80 physicians and surgeons, using the Spielberger State-Trait Anxiety Scale and the Beck Depression Inventory. 27 doctors were nonsmokers, 14 were former smokers, and 39 were current smokers. Current smokers showed significantly higher Anxiety and Depression scores compared to nonsmokers and former smokers, while the latter presented significantly lower Anxiety scores than nonsmokers. In current smokers, the daily quota of cigarettes was not correlated with Anxiety or Depression scores. From our results we can hypothesize that, among medical staff, smoking behavior is more anxiety-related than depression-related. In conclusion, we believe that interventions such as stress management techniques could be effective in lessening Anxiety and diminishing the need for relief searched for in smoking.     

“I'll wait for the English one”: COVID-19 vaccine country of origin,national identity,and their effects on vaccine perceptions and uptake willingness

Vaccines can play a crucial role in reducing the negative outcomes of pandemics. In this paper we explore how vaccine perceptions and uptake willingness can be affected by vaccine-related information, the vaccine's country of origin, and national identity. Study 1 (N = 800) showed that a vaccine manufactured by China was perceived more negatively compared to vaccines from the UK, Germany, and Chile. Providing vaccine effectiveness information (83%) increased preference for waiting for an alternative vaccine and reduced perceived effectiveness of a vaccine from China. Brexit supporters perceived vaccines as less safe in general, and particularly thought of a vaccine from China as less competent, effective, and trustworthy, and were less prepared to have it. Study 2 (N = 601) largely replicated findings of Study 1 regarding the effects of a vaccine's country of origin. Moreover, participants who reported a higher sense of British superiority reported more negative attitudes towards a vaccine from China. However, apart from the aforementioned main effects of Study 2, our attempt to manipulate British identity vis a vis a Global identity in order to examine particular national-identity related outcomes was not successful. Overall, vaccine characteristics can interact with various social psychological factors, potentially affecting people's perceptions and willingness to uptake particular measures to support personal and public health.     

Reduction of pairwise comparisons in decision making via a duality approach

Although pairwise comparisons have been seen by many as an effective and intuitive way for eliciting qualitative data for multi‐criteria decision making problems, a major drawback is that the number of the required comparisons increases quadratically with the number of the entities to be compared. Thus, often even data for medium size decision problems may be impractical to be elicited via pairwise comparisons. The more the comparisons are, the higher is the likelihood that the decision maker will introduce erroneous data. This paper introduces a dual formulation to a given multi‐criteria decision making problem, which can significantly alleviate the previous problems. Some theoretical results establish that this is possible when the number of alternatives is greater than the number of decision criteria plus one. Copyright © 1999 John Wiley & Sons, Ltd.     

Adaptation to an autoimmune disorder: Does mental flexibility impact illness-related self-regulation?

Objective: To examine whether mental flexibility moderates the relationship between illness representations of control and coping behaviour in individuals suffering from rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE).

Design: Recently, diagnosed RA (N = 80) and SLE (N = 75) patients completed questionnaires about illness representations of personal and treatment control and four coping behaviours: instrumental coping, adherence to medical advice, palliative coping and wishful thinking. Mental flexibility was assessed with the Trail Making Test Part B (TMT-B), while visuomotor processing speed, as a confounder, was assessed with the Trail Making Test Part A (TMT-A). Moderated mediation models were tested within a bootstrapped multiple regression framework.

Results: TMT-A scores had no statistically significant moderation effects on the relation between representations and coping behaviour. Conversely, in those participants with SLE, TMT-B scores moderated the relation of personal control to wishful thinking and palliative coping, as well as the relation of treatment control to both wishful thinking and palliative coping. All significant effects were restricted to the SLE group.

Conclusion: Interactions between neurocognitive factors and the process of illness adaptation may emerge early during the course of SLE. The present findings highlight the role of cognitive functioning as an integral part of the illness-related self-regulation mechanism.     

Antiabortion Rhetoric and the Undermining of Choice: Women's Agency as Causing “Psychological Trauma” Following the Termination of a Pregnancy

Historically the antiabortion movement has opposed abortions through reference to the fetus' human status. However, recently there has been a rhetorical shift whereby abortion is criticized based on its alleged negative psychological impact on women, with some authors voicing concerns related to this medicalized repertoire undermining women's capacity to act as rational decision-makers. However, no research to date has systematically analyzed how women's agency over their abortions features in antiabortion rhetoric. In this article, through a discourse analysis of interviews with 15 antiabortion supporters, I explore how psychological concepts are employed to indirectly undermine women's agency to abort. Participants construct the termination of a pregnancy as psychologically damaging when women's agency is evident (e.g., in abortions or rape-pregnancy abortions). Women's choice also appears as enforced by society, victimizing them and removing accountability over it. However, unintentional termination (e.g., miscarriage) is constructed as “natural” and psychologically harmless due to the lack of agency. Overall, the pathologization of abortion through reference to psychological trauma stemming from the exercise of agency allows antiabortionists to naturalize motherhood and oppose abortions in an “objective,” depoliticized, nonrestrictive, and prowoman manner, without explicitly disregarding women's ability to choose or breaching Western norms of autonomy and freedom of choice.     

Beat the Heat: Effects of a Motivational Self-Talk Intervention on Endurance Performance

The study examined the effects of a motivational self-talk intervention on endurance cycling performance in hot conditions. Participants were 16 physically active adult men. After a baseline VO₂ peak assessment and two training sessions, participants completed a 30 min cycling trial in a hot environment (35°C, 45% relative humidity) while maintaining a steady rate of perceived exertion. Participants of the intervention group produced greater power output during the final third of the trial. Findings suggest that the self-talk strategy seems to have compromised the aversive effects of the demanding environmental conditions and provide support for the psychobiological model of endurance performance.     

Skills Evaluator: a multicriteria decision support system for the evaluation of qualifications and skills in Information and Communication Technologies

Employees need to acquire new qualifications throughout their lives in order to deal with the multiple changes in the labour market. This knowledge and competences (formally or non-formally acquired) must be identified and evaluated. For that reason, an integrated approach to the evaluation of Information and Communication Technology knowledge and skills is proposed. The multicriteria method that has been developed refers to professionals who wish to be accredited in a particular specialization through the evaluation of their professional experience, studies and vocational training. The aim of this paper is to present the multicriteria decision support system, Skills Evaluator, which brings into effect the aforementioned method. Copyright © 2007 John Wiley & Sons, Ltd.     

Desensitization of postsynaptic glutamate receptors contributes to high-frequency homosynaptic depression of aplysia sensorimotor connections

Withdrawal reflexes of Aplysia are mediated in part by a monosynaptic circuit of sensory (SN) and motor (MN) neurons. A brief high-frequency burst of spikes in the SN produces excitatory postsynaptic potentials (EPSPs) that rapidly decrease in amplitude during the burst of activity. It is generally believed that this and other (i.e., low-frequency) forms of homosynaptic depression are entirely caused by presynaptic mechanisms (e.g., depletion of releasable transmitter). The present study examines the contribution that desensitization of postsynaptic glutamate receptors makes to homosynaptic depression. Bath application of cyclothiazide, an agent that reduces desensitization of non-NMDA glutamate receptors, reduced high-, but not low-frequency synaptic depression. Thus, a postsynaptic mechanism, desensitization of glutamate receptors, can also contribute to homosynaptic depression of sensorimotor synapses.     

The role of core self-evaluations in the relationship between religious involvement and subjective well-being: a moderated mediation model

This study examined whether core self-evaluations (CSE), a personality-based construct, mediates the association between religious involvement and subjective well-being (i.e., physical and psychological). Furthermore, investigates whether the indirect relation of religious involvement to well-being through CSE is conditional on age group (elderly vs. adults). Two different samples were examined: an elderly (N?=?300) and an adult community sample (N?=?294). To determine whether the strength of these effects depend on (moderated by) age group, we used multiple regression analyses and bootstrapping framework to probe conditional indirect (i.e., moderated mediation) effects. The results showed that CSE mediates the relationship between religious involvement (i.e., religious attendance and intrinsic religiosity) and both aspects of subjective well-being. However, the moderated mediation models revealed that this mechanism exists only for elderly. Implications of these results for improving the quality of life in elderly are discussed and directions for future research are provided.     

The Greek Version of the Difficulties in Emotion Regulation Scale: Testing the Factor Structure, Reliability and Validity in an Adult Community Sample

We examined the factor structure, reliability, convergent and criterion validity of the Greek version of the Difficulties in Emotion Regulation Scale (DERS) using data from a community lifespan sample. Exploratory and confirmatory factor analyses revealed a clear six-factor structure consistent with the factor structure evidenced in English-speaking samples. The results also demonstrated adequate classical psychometric properties in terms of internal consistency and test-retest reliability. The scale branches demonstrated convergent and concurrent validity with personality, emotion intelligence abilities and coping strategies. The importance of using culturally validated dimensional measures of emotion regulation is discussed.
