Disaster recovery work increases risk for mental health problems, yet the mechanisms underlying this association are unclear. We explored links from recovery work to post‐traumatic stress (PTS), major depression (MD), and generalized anxiety disorder (GAD) symptoms through physical health symptoms and household income in the aftermath of the Deepwater Horizon oil spill. As part of the NIEHS GuLF STUDY, participants (= 10,141) reported on cleanup work activities, spill‐related physical health symptoms, and household income at baseline, and mental health symptoms an average of 14.69 weeks (SD = 16.79) thereafter. Cleanup work participation was associated with higher physical health symptoms, which in turn were associated with higher PTS, MD, and GAD symptoms. Similar pattern of results were found in models including workers only and investigating the influence of longer work duration and higher work‐related oil exposure on mental health symptoms. In addition, longer worker duration and higher work‐related oil exposure were associated with higher household income, which in turn was associated with lower MD and GAD symptoms. These findings suggest that physical health symptoms contribute to workers’ risk for mental health symptoms, while higher household income, potentially from more extensive work, might mitigate risk.  相似文献

People use the word “violent” to describe a wide range of behaviors. When referring to acts of force, however, past research indicates that people often reserve the word “violent” to refer to acts of force that they define as “bad.” In the current study we use vignettes to explore variation in people’s definitions of a particular instance of the use of force. The findings indicate support for the idea that people reserve the word “violent” to refer to acts of force they view as “bad.” Findings indicate there is variation in perceptions of the level of violence, and whether the incident was even violent. Characteristics of the incident as well as the gender of those involved account for the majority of the variance explained.  相似文献

The process of identity formation as a central task of adolescence is difficult and fragile but even more so in adolescents with a migration background. Confronted with adverse experiences, cultural peculiarities of the country of origin can aggravate the second individuation phase of the adolescent, superimposed by a third phase caused by migration (Blos, Ahktar). With three case reports of mentally disturbed adolescents from different migration backgrounds, some specific dangers of such borderland adolescents are presented. All three cases have something in common: the importance of the glorified militant ideologies of the country of origin influencing the mental disorder of the adolescent in a special way such as a suitable target of narcissistic self-aggrandizement. The dangers of diagnostic colonization of alien symptoms and reactivation of elements of the Nazi past into the present with offender-victim constellations triggered by alienation are pointed out and discussed. The inability to draw borderlines between reality and fantasy and transmissive and deposed conflicts are described.  相似文献

With the stage set by the overview of supervision models in the previous paper, thispaper now presents the development and evolution of a currently ongoing leader-ledsupervision group for experienced genetic counselors. I discuss the procedures forgetting started; the creation and maintenance of the contract; typical issues and themesconsidered; the format for case presentation; and the overall growth of the group and itsmembers.  相似文献

A common way of studying developmental disorders is to adopt a static neuropsychological deficit approach, in which the brain is characterized in terms of a normal brain with some parts or ‘modules’ impaired. In this paper we outline a neuroconstructivist approach in which developmental disorders are viewed as alternative developmental trajectories in the emergence of representations within neural networks. As a concrete instantiation of the assumptions underlying this general approach, we present a number of simulations in an artificial neural network model. The representations that emerge under different architectural, input and developmental timing conditions are then analysed within a multi‐dimensional state space. We explore alternative developmental trajectories in these simulations, demonstrating how initial differences in the same parameter can lead to very different outcomes, and conversely how different starting states can sometimes result in similar end states (phenotypes). We conclude that the assumptions of the neuroconstructivist approach are likely to be more appropriate for analysing developmental deviations in complex dynamic neural networks, such as the human brain.  相似文献

This study explores the profile of 364 Anglican clergy serving in the Church in Wales (264 clergymen, 93 clergywomen, and 7 who did not disclose their sex) on the Schutte Emotional Intelligence Scale. The data confirm the finding from three earlier studies of church leaders in Britain that both male and female clergy in Britain record significantly lower levels of emotional intelligence in comparison with the standardization data published for this scale. Closer investigation of the scale items, however, questions whether this instrument may offer a fair assessment of the kind of emotional intelligence best suited for pastoral ministry.

In executing purposeful actions, adults select sufficient and necessary limbs. But infants often move goal‐irrelevant limbs, suggesting a developmental process of motor specialization. Two experiments with 9‐ and 12‐month‐olds revealed gradual decreases in extraneous movements in non‐acting limbs during unimanual actions. In Experiment 1, 9‐month‐olds produced more extraneous movements in the non‐acting hand/arm and feet/legs than 12‐month‐olds. In Experiment 2, analysis of the spatiotemporal dynamics of infants’ movements revealed developmental declines in the spatiotemporal coupling of movements between acting and non‐acting arms. We also showed that the degree of specialization in infants’ unimanual actions is associated with individual differences in motor experience and visual attention, indicating the experience‐dependent and broad functional nature of these developmental changes. Our study provides important new insights into motor development: as in cognitive domains, motor behaviours are initially broadly tuned to their goal, becoming progressively specialized during the first year of life.  相似文献

With advancing age, episodic memory performance shows marked declines along with concurrent reports of lower subjective memory beliefs. Given that normative age-related declines in episodic memory co-occur with declines in other cognitive domains, we examined the relationship between memory beliefs and multiple domains of cognitive functioning. Confirmatory bi-factor structural equation models were used to parse the shared and independent variance among factors representing episodic memory, psychomotor speed, and executive reasoning in one large cohort study (Senior Odyssey, N = 462), and replicated using another large cohort of healthy older adults (ACTIVE, N = 2802). Accounting for a general fluid cognitive functioning factor (comprised of the shared variance among measures of episodic memory, speed, and reasoning) attenuated the relationship between objective memory performance and subjective memory beliefs in both samples. Moreover, the general cognitive functioning factor was the strongest predictor of memory beliefs in both samples. These findings are consistent with the notion that dispositional memory beliefs may reflect perceptions of cognition more broadly. This may be one reason why memory beliefs have broad predictive validity for interventions that target fluid cognitive ability.  相似文献

With an increasingly aging population, more work is needed to identify factors which may promote the maintenance of normal cognitive functioning. The current study tested the concurrent association between sense of purpose in life and the cognitive variables of episodic memory, executive functioning, and composite cognitive functioning in adults (N = 3489, Mage = 56.3 years, SD = 12.27, Range = 32–84 years) from the Midlife in the United States study (MIDUS). Correlational analyses suggested that purpose in life was associated with higher scores for memory, executive functioning, and overall cognition. Bootstrapping tests of moderation found no evidence for a moderating effect of age on purpose and the cognitive variables. Future studies should attempt to explain the mechanisms behind this relationship and explore the potential for interventions to promote healthy cognitive and purposeful aging.  相似文献
