Interpersonal relationships have been shown to be an important component of the psychosocial work environment that may affect health, job satisfaction, and productivity. The question whether interpersonal relationships at work are influenced by other psychosocial working conditions such as demands and control has not been studied. The aim of the present study is to investigate if high work demands and aspects of low work control could predict three indicators of detrimental interpersonal relationships at work. In a representative Swedish cohort study, data were obtained in two waves three years apart from 4049 participants, who did not change their jobs between the waves. These data were analysed by multiple logistic regression analyses. Odds ratios adjusted for possible confounders and negative interpersonal relationships at base-line showed that high demands predicted serious conflict and exclusion by co-workers. Low skill discretion predicted exclusion by co-workers. It is argued that these prospective findings are of relevance to interventions targeting troublesome and detrimental interpersonal relationships at work and that the findings can be important in understanding the development of work-related mental ill-health. 相似文献

The paper presents an infinite hierarchy PR m [m = 1, 2, . . . ] of sound and complete axiomatic systems for modal logic with graded probabilistic modalities, which are to reflect what I have elsewhere called the Bolding-Ekelöf degrees of evidential strength as applied to the establishment of matters of fact in law-courts. Our present approach is seen to differ from earlier work by the author in that it treats the logic of these graded modalities not only from a semantical or model-theoretic viewpoint but from a prooftheoretical and axiomatic stance as well. A paramount feature of the approach is its use of so-called systematic frame constants as labels of diverse grades of probability. Apart from this novel feature our approach can be seen to go back to pioneering work by Lou Goble in 1970. 相似文献

We consider three infinite hierarchies of what I call “two-dimensional temporal logics with explicit realization operators”, viz. (i) one without historical or deontic modalities, (ii) one with historical but without deontic modalities, and (iii) one with historical and with dyadic deontic modalities for conditional obligation and permission. Sound and complete axiomatizations are obtained for all three hierarchies relative to a simplified version of the finite co-ordinate-system semantics given for so-called T × W logic of historical necessity in [L. Åqvist, The logic of historical necessity as founded on two-dimensional modal tense logic, J. Philos. Logic 28 (1999) 329–369]. 相似文献

Although 14% to 42% of people with whiplash injuries end up with chronic debilitating pain, there is still a paucity of empirically supported treatments for this group of patients. In chronic pain management, there is increasing consensus regarding the importance of a behavioural medicine approach to symptoms and disability. Cognitive behaviour therapy has proven to be beneficial in the treatment of chronic pain. An approach that promotes acceptance of, or willingness to experience, pain and other associated negative private events (e.g. fear, anxiety, and fatigue) instead of reducing or controlling symptoms has received increasing attention. Although the empirical support for treatments emphasizing exposure and acceptance (such as acceptance and commitment therapy) is growing, there is clearly a need for more outcome studies, especially randomized controlled trials. In this study, participants (N = 21) with chronic pain and whiplash-associated disorders were recruited from a patient organization and randomized to either a treatment or a wait-list control condition. Both groups continued to receive treatment as usual. In the experimental condition, a learning theory framework was applied to the analysis and treatment. The intervention consisted of a 10-session protocol emphasizing values-based exposure and acceptance strategies to improve functioning and life satisfaction by increasing the participants' abilities to behave in accordance with values in the presence of interfering pain and distress (psychological flexibility). After treatment, significant differences in favor of the treatment group were seen in pain disability, life satisfaction, fear of movements, depression, and psychological inflexibility. No change for any of the groups was seen in pain intensity. Improvements in the treatment group were maintained at 7-month follow-up. The authors discuss implications of these findings and offer suggestions for further research in this area. 相似文献

We consider a version of so called T × W logic for historical necessity in the sense of R.H. Thomason (1984), which is somewhat special in three respects: (i) it is explicitly based on two-dimensional modal logic in the sense of Segerberg (1973); (ii) for reasons of applicability to interesting fields of philosophical logic, it conceives of time as being discrete and finite in the sense of having a beginning and an end; and (iii) it utilizes the technique of systematic frame constants in order to handle the problem of irreflexivity in tense logics, well known since Gabbay (1981). Axiomatizations are given for two infinite hierarchies of two-dimensional modal tense logics, one without and one with the characteristic operators for historical necessity and possibility. Strong and weak completeness results are obtained for both hierarchies as well as a result to the effect that two approaches to their semantics are equivalent, much in the spirit of Di Maio and Zanardo (1996) and von Kutschera (1997). 相似文献

This study examined the prevalence of self-reported depressive symptoms in a Swedish urban school sample (n=547) aged 13 to 18 years using the Beck Depression Inventory (BDI). The data obtained were examined with respect to sex and age differences and compared with a clinical sample of adolescents hospitalized because of psychiatric disturbances. The results indicated a strong preponderance of depressive symptoms among girls in the school sample, in particular for the severe symptom level. Eight percent of subjects reported depressive symptoms sufficiently high to be classified as a moderate, and 2% as a severe, level of depression. Factor analysis yielded four factors representing dysphoric mood, social activity, relationship, and food-related dimensions. The BDI showed a high internal consistency, and test-retest reliability calculated for a 2-week and a 2-month interval revealed strong correlations. The means of total scores on the BDI for the clinical sample were significantly higher than for those in the school sample. 相似文献

Genetic and environmental influences on the association between performance‐based self‐esteem and exhaustion: A study of the self‐worth notion of burnout 下载免费PDF全文
Pia Svedberg Lennart Hallsten Jurgita Narusyte Lennart Bodin Victoria Blom 《Scandinavian journal of psychology》2016,57(5):419-426
In the self‐worth model, burnout is considered to be a syndrome of performance‐based self‐esteem (PBSE) and experiences of exhaustion. Studies have shown that PBSE and burnout indices such as Pines’ Burnout Measure (BM) are associated. Whether these variables have overlapping etiologies has however not been studied before. Genetic and environmental components of covariation between PBSE and exhaustion measured with Pines’ BM were examined in a bivariate Cholesky model using data from 14,875 monozygotic and dizygotic Swedish twins. Fifty‐two per cent of the phenotypic correlation (r = 0.41) between PBSE and Pines’ BM was explained by genetics and 48% by environmental factors. The findings of the present study strengthen the assumption that PBSE should be considered in the burnout process as proposed by the self‐worth conception of burnout. The present results extend our understanding of the link between this contingent self‐esteem construct and exhaustion and provide additional information about the underlying mechanisms in terms of genetics and environment. This finding corroborates the assumed syndrome view on burnout, while it also suggests an altered view of how the syndrome emerges and how it can be alleviated. 相似文献
