Background and Objectives: Workplace bullying has been classified as an extreme social stressor in work contexts and has been repeatedly linked to several negative consequences. However, little research has examined reversed or reciprocal relations of bullying and outcomes. Design: We conducted a two-wave longitudinal study with a time lag of six months. Methods: The study sample consisted of 348 employees of the Spanish workforce. The present study examined longitudinal relationships between workplace bullying, psychological health, and well-being. On the basis of conservation of resources theory, we hypothesized that we would find reciprocal relations among study variables over time. Results: Results of cross-lagged structural equation modeling analyses supported our hypotheses. Specifically, it was found that Time 1 (T1) workplace bullying was negatively related to Time 2 (T2) vigor and positively related to T2 anxiety. Additionally, T1 anxiety and vigor had an effect on T2 workplace bullying. Conclusions: Overall, these findings support the validity of the theoretical models postulating a reciprocal bullying–outcome relationship, rather than simple one-way causal pathways approaches.  相似文献

In this article the process of assimilation in the problematic experience of tiredness of one patient, María, is shown. María was treated with linguistic therapy of evaluation (LTE), a therapy midway between constructivist and cognitive therapies based on the theory of General Semantics, for 14 sessions. María was one of the most successful cases of LTE. Aims of the study were to show the process of assimilation in a case with good outcome and to explore if this process shows an irregular pattern, with setbacks or jumps between stages. This process is analyzed by the Assimilation of Problematic Experiences Scale (APES), an eight-stage scale that shows the process of assimilation from an experience being warded off, avoided, in vague awareness, clarified, understood, solutions applied, and finally resolved and integrated into the self. Results showed, first, that the process of assimilation reaches APES Stages 5 (application) and 6 (problem solution), and, second, that the process of assimilation showed a clear sawtoothed, irregular pattern.  相似文献

Previous work has generated inconsistent results with regard to what extent working memory (WM) content guides visual attention. Some studies found effects of easy to verbalize stimuli, whereas others only found an influence of visual memory content. To resolve this, we compared the time courses of memory-based attentional guidance for different memory types. Participants first memorized a colour, which was either easy or difficult to verbalize. They then looked for an unrelated target in a visual search display and finally completed a memory test. One of the distractors in the search display could have the memorized colour. We varied the time between the to-be-remembered colour and the search display, as well as the ease with which the colours could be verbalized. We found that the influence of easy to verbalize WM content on visual search decreased with increasing time, whereas the influence of visual WM content was sustained. However, visual working memory effects on attention also decreased when the duration of visual encoding was limited by an additional task or when the memory item was presented only briefly. We propose that for working memory effects on visual attention to be sustained, a sufficiently strong visual representation is necessary.  相似文献

Two studies were conducted to examine how home healthcare nurses stay engaged in their work and maintain their psychological well-being. In Study 1, we hypothesized that nurses would perceive work pressure more as a hindrance demand than as a challenge demand, and that the reverse would be true for emotional demands. We approached 120 home healthcare nurses who filled in a survey. Results of a series of paired sample t-tests supported our hypotheses. In Study 2, we used the JD-R model to hypothesize that weekly job demands can either facilitate or undermine the positive impact of personal resources on work engagement and flourishing, depending on the nature of the job demand (hindrance vs. challenge). A sample of 63 nurses filled in a questionnaire at the end of the working week during three consecutive weeks (N = 3 × 63 = 189 occasions). Results of hierarchical linear modeling showed that emotional job demands strengthened the effect of personal resources on weekly well-being, whereas work pressure undermined this effect. Taken together, the present findings challenge the idea that whether job demands act as hindrances or challenges is the same for all occupations and for all individuals.  相似文献

The authors examined the relationship between newborn neurobehavioral profiles and the characteristics of early mother-infant interaction in Nagasaki, Japan. The authors administered the Brazelton Neonatal Behavioral Assessment Scale (NBAS; T. B. Brazelton &; J. K. Nugent, 1995) in the newborn period and the Nursing Child Assessment Teaching Scale at 1 month (NCATS; G. Sumner &; A. Spietz, 1994). They administered the Perceived Stress Scale (S. Cohen, T. Kamarck, &; R. Mermelstein, 1983) as an index of maternal stress experienced over the past month. Lower irritability, higher stability in skin coloration, and lower tremulousness in the neonatal period were correlated with higher levels of maternal nurturing behaviors at 1 month. Birth weight and 2 NBAS range-of-state items (peak of excitement, irritability) predicted 31% of the variance in NCATS caregiver subscale score. The NBAS autonomic stability items (tremulousness, startles, lability of skin color) predicted 31% of the variance in the NCATS child subscale score. Perceived stress and maternal sociodemographic variables (education, income, age, parity) were not associated with child, caregiver, and total scores on the NCATS. The results suggested that lack of autonomic stability in Japanese neonates might serve as an early indicator of infant frailty, negative behavioral cues, and decreased maternal responsiveness.  相似文献

This study aims at exploring a structural model of satisfaction with life’s (SWL) predictors in a cross-national sample of older adults. A quantitative approach was followed with a cross-sectional study design. A community-dwelling sample of 1,234 older adults from four different nationalities residing in Portugal, was assessed regarding SWL, sense of coherence (SOC) and socio-demographic, lifestyle and health-related characteristics. Sampling was performed in lifelong learning centres’ message boards and local community centres’ list-serves in the Lisbon metropolitan area and in the Algarve region. Structural equation modeling was used to investigate a structural model of the self-reported SWL, comprising SOC, socio-demographic characteristics (age, sex, education, marital and professional status, household, adult children, income, living setting and religion), as well as lifestyle and health-related characteristics (physical activity, recent disease and medication). Significant predictors are SOC (β?=?0.733; p?<?0.001), religion (β?=?0.725; p?<?0.001), income (β?=?0.551; p?<?0.001), adult children (β?=?0.546; p?<?0.001), education (β?=??0.403; p?<?0.001), living setting (β?=??0.292; p?<?0.001) and medication (β?=??. 197; p?<?0.001). The variables accounted for 24.8 % of the variability of SWL. Moreover, differences between the four nationality groups (F (3, 671)?=?3.671, p?=?0.066) were not found concerning SWL. Sense of coherence is the strongest predictor of self-reported SWL. Other predictors are religion, income, adult children, education, living setting and medication. The four nationalities did not present significant differences, concerning SWL. This study points out the potential factors that influence older adults’ SWL, in particular SOC, religion and income, as promoters of aging well, within a salutogenic model of health for older populations.  相似文献

Previous research on the contribution of top-down control to saccadic target selection has suggested that eye movements, especially short-latency saccades, are primarily salience driven. The present study was designed to systematically examine top-down influences as a function of time and relative salience difference between target and distractor. Observers performed a saccadic selection task, requiring them to make an eye movement to an orientation-defined target, while ignoring a color-defined distractor. The salience of the distractor was varied (five levels), permitting the percentage of target and distractor fixations to be analyzed as a function of the salience difference between the target and distractor. This analysis revealed the same pattern of results for both the overall and the short-latency saccades: When the target and distractor were of comparable salience, the vast majority of saccades went directly to the target; even distractors somewhat more salient than the target led to significantly fewer distractor, as compared with target, fixations. To quantify the amount of top-down control applied, we estimated the point of equal selection probability for the target and distractor. Analyses of these estimates revealed that, to be selected with equal probability to the target, a distractor had to have a considerably greater bottom-up salience, as compared with the target. This difference suggests a strong contribution of top-down control to saccadic target selection—even for the earliest saccades.  相似文献

The study of family factors, (namely, parenting, attachment and family functioning) that can either reduce or increase risk factors during adolescent development is crucial to the early identification of adolescents at risk for self-destructive thoughts and behaviors (SDTB). Altough several studies have highlighted the role of family factors, few have analysed the joint impact of parenting styles and attachment in SDT. This study aimed to: (1) to identify the dimensions of parenting styles and parental attachment that predict SDTB; (2) to determine the mediation effect of cohesion on the relation between these predictors and reports of SDTB; and (3) to analyze sex and age differences in the abovementioned process. Participants included 1,266 Portuguese adolescents with a mean age of 15.9 years. Structural equation modeling demonstrated that paternal and maternal rejection and paternal control were the most accurate predictors of SDTB, emphasizing their role as risk factors for maladaptive trajectories with reports of SDTB. Results clearly emphasized the relevancy of the fathers’ role in such maladaptive trajectories. Additionally, a mediation effect of cohesion and a moderation of sex were also found. This study highlights the importance of intervening with the family in preventive and therapeutic contexts regarding adolescents’ well-being and their relationship with parents.  相似文献

In the present study, we present normative ratings of free association for 139 European Portuguese (EP) words among 7- to 8-, 9- to 10-, and 11- to 12-year-old children attending the 3rd, 5th, and 7th grades of elementary and middle school in Portugal. For each word, five indices are presented: (a) the percentage of associates, (b)?the strength of the first associate, (c)?the strength of the second associate, (d) the distance between the first and second associates, and (e)?the percentage of idiosyncratic responses. Additionally, grade-level frequency values for each word from the ESCOLEX database (Soares et al., in press) are also provided. As expected, the results revealed developmental changes in the knowledge organization of the children, which occurred at the ages of 9–10 (5th grade) and remained stable in the 11- to 12-year-old children (7th grade). Specifically, we observed a decrease in the percentages of associates and idiosyncratic responses, as well as an increase in the strengths of the first and second associates from the 3rd to the 5th grade. Moreover, a comparative analysis with the previous work of Carneiro, Albuquerque, Fernandez, and Esteves (2004) on EP and Macizo, Gómez-Ariza, and Bajo (2000) on Spanish, for the subsets of common words (16 and 58, respectively), showed that the present norms fit well with previous EP data, but differ from the Spanish data.  相似文献
