The aim of this study was to explore associations between mental and cancer-specific distress (psychological distress) and personality traits in healthy women belonging to families with familial cancer and absence of demonstrated mutations. We included 238 healthy women from families with familial breast-ovarian cancer (FBOC) or hereditary non-polyposis colorectal cancer (HNPCC). They responded to a questionnaire including validated instruments for psychological distress and personality traits. Information on demography and cancer-related issues were also collected. Significant associations between psychological distress and personality traits were found in these women. The traits of Optimism and Harm avoidance showed the strongest association with both types of distress. Associations between psychological distress and personality traits were observed in women from families with FBOC or HNPCC that fulfilled clinical criteria for familial breast/ovarian cancer in the absence of demonstrated mutations. Screening for such traits could be helpful in genetic counseling.  相似文献

This investigation explores the perceptions of intergenerational family conflict among 93 Asian American college students from immigrant families in relation to reported discrepancies in Asian values with their parents, behavioral acculturation, gender, and ethnicity (Chinese and Korean). The study is unique in its examination of parent gender and specific dimensions of Asian values as predictors of perceived parent-child conflict. The findings indicated that as discrepancies in Asian values with either parent increased, reports of parent-child conflict also increased. Values discrepancies, but not behavioral acculturation, were significantly associated with perceived family conflicts. Independent hierarchical regression models revealed a significant association between conflict ratings and values discrepancies with mothers on the dimension of Conforming to Family Norms, and with fathers on the dimension of Education/Career Issues. However, interaction effects within a combined model to test beta coefficients differences between parents were not significant. Results also suggest that intergenerational conflict may be associated with discrepancy on Respecting Elders. Implications and limitations of these findings are discussed.  相似文献

Using the think/no-think paradigm, we examined the effect of a meaningful connection between emotionally neutral cues and targets on initial learning and later recall by students in dysphoric or nondysphoric mood states. Compared to meaningfully connected cue-target pairs, unrelated pairs were less easily learned and more easily forgotten, even when initial learning was controlled. Depressive deficits were obtained in initial learning (only marginally) and final recall. When examined separately within each cuing condition, the recall deficit associated with depressed mood was restricted to the unrelated condition, but when initial learning differences were controlled this deficit was only marginally significant. Results are discussed in relation to other recent findings concerning depression-related performance in this paradigm and to findings of depression and memory more generally.  相似文献

The authors examine the reassessments of the National Reading Panel (NRP) report (National Institute of Child Health and Human Development, 2000) by G. Camilli, S. Vargas, and M. Yurecko (2003); G. Camilli, P. M. Wolfe, and M. L. Smith (2006); and D. D. Hammill and H. L. Swanson (2006) that disagreed with the NRP on the magnitude of the effect of systematic phonics instruction. Using the coding of the NRP studies by Camilli et al. (2003, 2006), multilevel regression analyses show that their findings do not contradict the NRP findings of effect sizes in the small to moderate range favoring systematic phonics. Extending Camilli et al. (2003, 2006), the largest effects are associated with reading instruction enhanced with components that increase comprehensiveness and intensity. In contrast to Hammill and Swanson, binomial effect size displays show that effect sizes of the magnitude found for systematic phonics by the NRP are meaningful and could result in significant improvement for many students depending on the base rate of struggling readers and the size of the effect. Camilli et al. (2003, 2006) and Hammill and Swanson do not contradict the NRP report, concurring in supporting comprehensive approaches to reading instruction.  相似文献

This research explores the mediating effects of severity of disability on the employment outcomes of participants with disabilities, taking into account their perception of interest‐job match. Participants were 115 high school students with disabilities who took part in an intensive school‐to‐work transition program that explored occupational interests in relation‐to‐work opportunities. Results of a 1‐way analysis of covariance indicated that severity of disability had a significant effect on the employment outcomes of participants despite interest‐job matching. Although participants experienced positive employment outcomes in terms of job entry, these outcomes may not necessarily translate into higher earnings.  相似文献

People are more forgiving toward transgressors if they see themselves as capable of committing similar offenses, as demonstrated in 7 studies. Methods included hypothetical scenarios, actual recalled offenses, individual and group processes, and correlational and experimental designs. Three factors mediated the link between personal capability and forgiveness: seeing the other's offense as less severe, greater empathic understanding, and perceiving oneself as similar to the transgressor. In terms of predicting forgiveness, it was important that people's own offenses were similar to the target offense in terms of both severity and type. The personal capability effect was independent of other established predictors of forgiveness and was more pronounced among men than women.  相似文献

Three studies tested whether adopting strong (relative to weak) approach goals in relationships (i.e., goals focused on the pursuit of positive experiences in one's relationship such as fun, growth, and development) predict greater sexual desire. Study 1 was a 6-month longitudinal study with biweekly assessments of sexual desire. Studies 2 and 3 were 2-week daily experience studies with daily assessments of sexual desire. Results showed that approach relationship goals buffered against declines in sexual desire over time and predicted elevated sexual desire during daily sexual interactions. Approach sexual goals mediated the association between approach relationship goals and daily sexual desire. Individuals with strong approach goals experienced even greater desire on days with positive relationship events and experienced less of a decrease in desire on days with negative relationships events than individuals who were low in approach goals. In two of the three studies, the association between approach relationship goals and sexual desire was stronger for women than for men. Implications of these findings for maintaining sexual desire in long-term relationships are discussed.  相似文献

Due to changes in state and federal policies, as well as logistical and fiscal limitations, researchers must increasingly rely on teachers' reports of school climate dimensions in order to investigate the developmental impact of these dimensions, and to evaluate efforts to enhance the impact of school environments on the development of young adolescents. Teachers' climate ratings exhibited a robust dimensional structure, high levels of internal consistency, and moderate levels of stability over 1-and 2-year time spans. Teachers' climate ratings were also found to be related consistently with students' ratings. In three large-scale samples of schools, teachers' climate ratings were associated significantly and consistently with students' performance on standardized tests of academic achievement, and with indexes of their academic, behavioral, and socio-emotional adjustment.  相似文献

This paper considers the relationship of unconscious fantasy to theory, with the focus on the issue of unity and multiplicity. The purpose of the paper is to explore the deep structure of unconscious fantasy, which is understood as that which promotes and organizes our experiences of the “one” and the “many” and serves as a driving force in the formation of the self. Using Thomas Ogden’s reformulation of Melanie Klein’s theory of fantasy (phantasy) and his vision of the Kleinian subject, alongside Christian Trinitarian theology, the paper argues that unity and multiplicity persist in a generative and interpenetrating dialectic that unfolds within/toward a transcendent unity-in-process, an eternal “becoming one.”  相似文献

The highly addictive drug methamphetamine has been associated with impairments in social cognitions as evidenced by changes in users' behaviors. Physiological changes in brain structure and functioning, particularly in the frontal lobe, have also been identified. The authors propose a biopsychosocial approach to understanding the effects of methamphetamine addiction by relating the physiological effects of the drug to the behaviors and social cognitions of its users, through the application of the theory of mind paradigm. Although onset of methamphetamine use has been linked to the desire for socialization, chronic use has been associated with an increase in depression, aggressiveness, and social isolation, behaviors that also implicate involvement of the frontal lobe. The reviewed literature provides strong circumstantial evidence that social-cognitive functioning is significantly impacted by methamphetamine use and that the social isolation, depression, and aggressiveness associated with chronic use is due to more than just the social withdrawal associated with addiction. Treatment considerations for methamphetamine must therefore consider the role of social cognition, and pharmacological responses must address the documented impact of the drug on frontal lobe functioning.  相似文献
