The mediational role of perceived stress in the relation between optimism and burnout in competitive athletes

Abstract

Burnout has been highlighted as an important issue, not only in occupational settings but also among athletes. Optimists appear to be more resistant to burnout, which might be partly explained by lower levels of stress. The purpose of this study was to investigate the relationship between optimism and burnout symptoms in 217 athletes (139 males and 78 females, aged 16 to 19 years), while also examining stress as a mediator in this relationship. The results showed that optimism had a significant negative relationship with both stress and burnout. Mediation analyses indicated that perceived stress fully mediated the links between optimism and two symptoms of burnout, emotional/physical exhaustion and sport devaluation, and partly mediated the link between optimism and a third symptom, reduced sense of accomplishment. The findings indicate that individual factors, such as optimism, may play an important role in the development of burnout by virtue of their association with stress. Future research should, therefore, investigate the longitudinal effects of optimism on stress and burnout.     

Psychophysiological effects of emotional dissonance in a face-to-face service interaction

Abstract

Current research demonstrates that requirements to express emotions which are not genuinely felt in the particular situation (emotional dissonance) are associated with negative long and short-term effects. The aim of the present study was to investigate: (a) the psychophysiological short-term effects of emotional dissonance in a face-to-face service interaction and (b) the moderating role of gender and neuroticism. In total, 32 women and 27 men were instructed to play the role of a service employee, who had to interact with an angry and rude customer. Half of the sample was given information that the organization expected them to be friendly (emotional dissonance), the other half was told they were expected to act naturally and show their genuine feelings (no emotional dissonance). Subjective and behavioral responses revealed that participants in the “friendly” condition modulated their emotional expressions to a greater extent than those in the “naturally” condition. Participants in the “friendly” condition showed stronger systolic and diastolic blood pressure responses. Furthermore, hierarchical regression analyses yielded that gender and neuroticism partly moderated the association between emotional dissonance and participants' psychophysiological response.     

Grace in Nature and History: Luther's Doctrine of Creation Revisited1

Abstract: Interpreting Luther's Trinitarian theology of creation, it is shown how Luther's doctrine of creation is modelled on his soteriology. In his writing Against Latomus(1521) Luther established his famous distinction between the external grace of God (favor dei) and the divine gift (donom): the living Christ. A similar distinction can be re‐constructed from Luther's theology of creation as presented in his catechisms, sermons, tracts, and exegetical writings. Just as Luther makes a distinction between the Christ who takes side for us within God, and the Christ who is dwelling in the heart of the believer, Luther makes a the distinction between the fatherly love toward humankind (benevolentia), and the Father, Son and Spirit, who are at work from within the life of the creatures in God's blessing (benedictio). There is an implicit notion of a pater pro nobis and a pater in nobis, which reflects, in the order of creation, the classic distinction between Christus pro nobis and Christus in nobis. According to Luther's theology of the Eucharist and divine blessing, there exists a union between God and creature, which has a similar structure as the union between Christ and believer. There are distinctions to be drawn as well as correlations to be seen between the order of creation and the order of salvation.     

Normality and naturalness: A comparison of the meanings of concepts used within veterinary medicine and human medicine

This article analyses the different connotations of “normality” and “being natural,” bringing together the theoretical discussion from both human medicine and veterinary medicine. We show how the interpretations of the concepts in the different areas could be mutually fruitful. It appears that the conceptions of “natural” are more elaborate in veterinary medicine, and can be of value to human medicine. In particular they can nuance and correct conceptions of nature in human medicine that may be too idealistic. Correspondingly, the wide ranging conceptions of “normal” in human medicine may enrich conceptions in veterinary medicine, where the discussions seem to be sparse. We do not argue that conceptions from veterinary medicine should be used in human medicine and vice versa, but only that it could be done and that it may well be fruitful. Moreover, there are overlaps between some notions of normal and natural, and further conceptual analysis on this overlap is needed.     

Cue abstraction and exemplar memory in categorization

In this article, the authors compare 3 generic models of the cognitive processes in a categorization task. The cue abstraction model implies abstraction in training of explicit cue-criterion relations that are mentally integrated to form a judgment, the lexicographic heuristic uses only the most valid cue, and the exemplar-based model relies on retrieval of exemplars. The results from 2 experiments showed that, in lieu of the lexicographic heuristic, most participants spontaneously integrate cues. In contrast to single-system views, exemplar memory appeared to dominate when the feedback was poor, but when the feedback was rich enough to allow the participants to discern the task structure, it was exploited for abstraction of explicit cue-criterion relations.     

Effectiveness of an ACT‐based rehabilitation program for the treatment of chronic fatigue: Results from a 12‐months longitudinal study

Acceptance and Commitment Therapy (ACT) is potentially effective for treating chronic fatigue. Given the paucity of studies on this topic, we aimed to assess long‐term trajectories of primary (fatigue, quality of life and functional abilities) and secondary outcomes (anxious and depressive symptoms) of an ACT‐based rehabilitation program for patients with chronic fatigue. Further, we examined if changes in potential process variables (psychological inflexibility, metacognitive beliefs, and cognitive and behavioral responses to symptoms) during ACT predicted change in all outcomes across follow‐up. One‐hundred ninety‐five workers on sick leave (mean age: 43.61 ± 9.33 years; 80.5% females) with a diagnosis of chronic fatigue were enrolled in a manualized, 3.5‐week intensive return‐to‐work rehabilitation program based on ACT. All completed a battery of questionnaires at pre‐, post‐treatment, 6 and 12 months follow‐up. We found significant longitudinal changes in most primary and secondary outcomes from pre‐ up to 12 months follow‐up. All process variables significantly decreased from pre‐ up to 12 months follow‐up, and pre‐to‐post changes in fear avoidance beliefs were most often associated with a greater change in outcomes across follow‐up. Depressive symptomatology showed a similar trajectory of change to fatigue, meaning that scores were correlated at each time point and tended to converge over time. This suggests that both symptoms influence each other substantially over a year following the treatment. Concluding, results lend support to the effectiveness of an ACT‐based rehabilitation program for patients with chronic fatigue and provide preliminary evidence for the role of process variables and depressive symptomatology on subsequent change in outcomes.
