Objective: Atypical patterns of cortisol secretion following an acute stressor have been commonly reported in breast cancer survivors. Stressful life events have been associated with blunted acute cortisol levels in other populations. The purpose of this study was to explore the role of stressful life events on cortisol secretion patterns of breast cancer survivors following an acute stressor.
Design: The Trier Social Stress (TSST) was used to elicit a moderate stress response in breast cancer survivors (n = 19) and a control group (n = 17). Saliva samples were collected before, during and after the TSST to provide cortisol concentrations. During recovery, we recorded the frequency and subjective impact of stressful life events in the past year using the Life Experience Survey.
Results: Simple regressions analyses were performed; results suggest no group differences between the total number of stressful life events and their subjective impact. However, the total number of stressful life events as well as their subjective impact correlated negatively with the peak cortisol concentration in breast cancer survivors.
Conclusions: The cumulative effect of stressful life events, positive and negative, may impact the endocrine stress system of breast cancer survivors more so than that of women with no history of cancer. 相似文献
Asthma remains the most prevalent chronic illness among children. Despite the substantial body of literature examining children with asthma, few studies have examined parents’ perspectives of the condition and experiences of caregiver stress. Parents of children with chronic illnesses experience elevated stress and may have limited opportunities to cope with complex emotions while caring for children with asthma. Drawing from focus groups and interviews with African American and Hispanic parents of children with asthma, this qualitative study was conducted as part of a patient-centered engagement process to inform the refinement of an intervention aimed at reducing stress among parents of children with asthma. All data were transcribed and underwent three waves of inductive analysis. The content analysis indicated that the unpredictable nature of asthma and the caregiving burden associated with managing children’s asthma contributed to parents’ stress, and external contexts compounded the impact of these stressors. Parents also reported having difficulty identifying how they coped with stress and employed approaches to coping with stress that they applied intermittently but encountered several barriers to enacting known or available coping strategies. Analyses also revealed that parents desired a multimodal stress reduction intervention that emphasized building relationships, allowed for flexibility, and encouraged staff-parent communication. Whereas African American and Hispanic parents’ experiences of stress and coping strategies were similar, their preferences differed in regards to incorporating technology into the intervention, the credentials of facilitators, and the salience of language preferences. Understanding the complexities of stressors facing caregivers is important for developing interventions to support parents and children coping with asthma, and in particular when working with families from diverse backgrounds. 相似文献
Although sociologists have argued that religious orders fulfill the same creative functions within Catholicism that sectarian groups perform for Protestantism, no research has examined whether the orders can serve this function in non-Western societies where Catholics are a minority. This article examines Catholic religious orders of women in mainland China today. Both internal and external factors prevent Chinese sisters from gaining the power and autonomy they would need to serve as change agents in the Chinese Catholic Church. The effectiveness of external attempts to ameliorate the sisters' difficulties is evaluated. 相似文献
Disputes by their nature involve contentious behavior. If one attributes such behavior to underlying personality traits, these attributions can be quite damning. The current research investigated negative trait attributions and their impact on dispute resolution decisions. We hypothesized that judging one's opponent to be low in agreeableness and high in emotionality (e.g. stubborn and volatile) shifts one's preference towards more formal procedures – formal in the sense that a third party judge controls the process and outcome. Drawing on the attribution literature, we hypothesized that two antecedents of these judgments (and consequent preferences) are the perceiver's level of prior information and the perceiver's cultural proclivity to explaining behavior in terms of personal dispositions. Results of an experiment measuring reactions to a hypothetical dispute found that prior information and culture (USA vs Hong Kong) increased trait attributions and preferences for formal procedures. Additionally, expectancy measures showed interaction effects suggesting that disputants dynamically construct expectancies in light of their personality impressions. 相似文献
American women still confront workplace barriers (e.g., bias against mothers, inflexible policies) that hinder their advancement at the upper levels of organizations. However, most Americans fail to recognize that such gender barriers still exist. Focusing on mothers who have left the workforce, we propose that the prevalent American assumption that actions are a product of choice conceals workplace barriers by communicating that opportunities are equal and that behavior is free from contextual influence. Study 1 reveals that stay-at-home mothers who view their own workplace departure as an individual choice experience greater well-being but less often recognize workplace barriers and discrimination as a source of inequality than do mothers who do not view their workplace departure as an individual choice. Study 2 shows that merely exposing participants to a message that frames actions in terms of individual choice increases participants' belief that society provides equal opportunities and that gender discrimination no longer exists. By concealing the barriers that women still face in the workplace, this choice framework may hinder women's long-term advancement in society. 相似文献
In the present study, we investigated response decisions made under conditions of incomplete information in rats. In Experiment
1, rats were trained on either a positive patterning (PP; A-, B-, AB+) or a negative patterning (NP; A+, B+, AB-) instrumental
lever-press discrimination. Subjects that had learned an NP discrimination responded less to Cue A when Cue B was covered
at test. The cover did not, however, affect test responses to Cue A in the PP condition. In Experiment 2, rats received concurrent
training on both PP and NP discriminations. After concurrent training, responses to Cue A were different with B covered versus
uncovered for both NP and PP discriminations. We discuss possible accounts for why exposure to a nonlinearly soluble discrimination
(NP) may have affected sensitivity to cue ambiguity produced by the cover. These results have interesting implications for
representational processes engaged in problem solving. 相似文献
