This study aimed to explore health professionals' views and practice regarding the provision of information about health-protective behaviors (e.g., exercise, alcohol consumption, diet) during genetic consultation for breast cancer. Ten genetic counselors participated in three focus groups, and seven medical specialists were interviewed in a focus group or individually. Data was analyzed using the constant comparative method. Findings suggested that health professionals held differing, often opposing, views about the value of health-protective behaviors for women at increased risk of breast cancer. The content and extent of information provided about health-protective behaviors varied widely, and participants expressed a need to form consensus regarding information provision both within and across clinics. The main barriers to providing information regarding health-protective behaviors included the lack of research evidence regarding the impact of these factors and higher priority of other information need to be provided in the limited consultation time. Participants generally did not consider it their role to promote health-protective behaviors, and were concerned about the psychological impact of providing information about behavioral risk factors during genetic consultations. 相似文献

A new grouping principle, uniform connectedness (UC), has been posited to be a basic organizer of visual pattern information,
one that takes precedence over other, more classic grouping principles (Palmer & Rock, 1994), but its ontogenetic origins
have not previously been investigated. We examined whether 3- to 4-month-olds and 6- to 7-month-olds utilize UC to organize
static two-dimensional displays. Infants habituated to uniformly connected patterns exhibited a novelty preference for disconnected
element patterns, whereas those without any habituation failed to exhibit a preference. The results indicate that infants
are sensitive to UC as a cue for perceptual organization. Prior studies indicate that some Gestalt principles (e.g., common
movement) are functional during the first half year of life, but that other principles (e.g., form similarity) are less readily
available. The present finding showing that young infants are sensitive to UC points to the foundational nature of this cue
and adds to an emerging body of evidence indicating that at least some of the mechanisms believed to produce perceptual organization
in adults are already operational in the first months of life. nt]mis|This research was supported by grants from the National

Following initial encoding, memories undergo a prolonged period of reorganization. While such reorganization may occur in many different memory systems, its purpose is not clear. Previously, we have shown that recall of recent contextual fear memories engages the dorsal hippocampus (dHPC). In contrast, recall of remote contextual fear memories engages a number of different cortical regions, including the anterior cingulate cortex (ACC). To examine whether this reorganization leads to greater memory stability, we examined reconsolidation of 1 d-old (recent) and 36 d-old (remote) contextual fear memory in mice. We infused the protein synthesis inhibitor, anisomycin (ANI), into either the dHPC or ACC immediately following retrieval of either a recent or remote contextual fear memory. In the dHPC, ANI infusions disrupted subsequent expression of recent, but not remote, contextual fear memory. Similar infusions into the ACC had no effect on either recent or remote contextual fear memories, whereas systemically applied ANI blocked subsequent remote memory expression when long re-exposure durations were used. Together, these data suggest that as memories mature they become increasingly stable. Furthermore, the dissociation between the effects of systemically and centrally administered ANI on remote memory suggests that stability is due, in part, to the distributed nature of remote contextual fear memories. 相似文献

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Personality Psychopathology-Five (PSY-5) scales were developed to measure abnormal personality symptomatology. The present study examines the incremental validity of the PSY-5 scales beyond the clinical and content scales in assessing criteria associated with personality disorders. The current sample includes 240 male and 407 female clients from private practice settings who completed the MMPI-2 and the Multiaxial Diagnostic Inventory (MDI), a self-report checklist of Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised) symptoms. Six of the MDI personality disorder scales, conceptually related to the PSY-5 scales, are used as criteria. Hierarchical regression analyses determine the incremental validity of each PSY-5 scale. In most analyses, PSY-5 scales add a significant increment of variance to the clinical and content scales. Implications of the results are discussed. 相似文献

Emotional intelligence (EI) may predict stress responses and coping strategies in a variety of applied settings. This study compares EI and the personality factors of the Five Factor Model (FFM) as predictors of task-induced stress responses. Participants (N = 200) were randomly assigned to 1 of 4 task conditions, 3 of which were designed to be stressful. Results confirmed that low EI was related to worry states and avoidance coping, even with the FFM statistically controlled. However, EI was not specifically related to task-induced changes in stress state. Results also confirmed that Neuroticism related to distress, worry, and emotion-focused coping, and Conscientiousness predicted use of task-focused coping. The applied utility of EI and personality measures is discussed. 相似文献

In this study the authors used cluster analysis to create racial identity profiles for a sample of Asian Americans using the People of Color Racial Identity Attitudes Scale (PCRIAS). A four-cluster solution was chosen: each cluster corresponded to one PCRIAS subscale and was named accordingly. Scores on the Asian American Racism-Related Stress Inventory and the Color-Blind Racial Attitudes Scale were compared across clusters. As expected, the Dissonance and Immersion clusters were characterized by relatively high racism-related stress and low levels of color-blind attitudes; the Conformity cluster showed roughly the opposite pattern. Surprisingly, the Internalization cluster showed a pattern similar to that for Conformity and thus may reflect "pseudoindependence" as discussed by Helms. 相似文献

- In this study, we deal with the existing debate related to the establishment of switching barriers retaining customers in the relationship with a provider. In particular, we demonstrate that ‘positive’ switching barriers (relational benefits) play a greater role that the ‘negative’ ones (switching costs and availability and attractiveness of other providers' offers) in determining customer satisfaction and retention. On the other hand, we include customers' need for variety in the proposed model, in order to demonstrate that a higher level of this psychological trait will lead to a lower perception of the existence of switching barriers. The hypotheses proposed have been tested for a services context on a sample of 800 individuals, using the technique ‘Partial Least Squares’ (PLS). Our findings lead to some interesting managerial implications.

Although a range of methods allow investigators to measure the local dependencies among behaviors in a sequence, only indirect
methods are available for measuring the interrelationships among behaviors across an entire sequence. This article introduces
a new “proximity” coefficient that measures interrelationships among behaviors as a direct function of their intrinsic organization
within a sequence. The coefficient does not depend on a user-defined “window” of analysis and provides an efficient use of
data that facilitates comparisons across actors, over time periods, and between single cases. An analysis of artificial data
shows further properties of the coefficient, including a diagonal value that reflects the degree to which a behavior is reciprocated,
and an asymmetry in values that depicts the relative precedence among behaviors. Extensions of the coefficient to the multivariate
case, and its relation to existing methods of analyzing sequences, are discussed. 相似文献
