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

This study investigated DSM-defined anxiety symptoms in South African youths. Children and adolescents (N = 701) from various cultural groups completed the SCARED and a questionnaire measuring perceived parental rearing behaviors. Results indicated that the psychometric properties of the SCARED were satisfactory in the total sample of South African youths, and acceptable in colored and black children and adolescents. Further, colored and black youths displayed higher SCARED scores than white youths, and there were also differences in the perceived parental rearing behaviors of the cultural groups. White youths generally rated their parents' rearing behaviors as less anxious, overprotective, and rejective, but more emotionally warm than colored and black youths. Finally, positive correlations were found between anxious rearing, overprotection, and rejection and anxiety symptoms. The clinical and research implications of these findings are briefly discussed.  相似文献

This study examined religious involvement and its association to risk behaviors (sexual behavior, marijuana use, alcohol use, and cigarette use) among older youth in foster care (N=383). Three dimensions of religious involvement were assessed—church or religious service attendance, religious practices, and religious beliefs. Findings showed that gender, ethnic group membership, sexual abuse history, and placement type were significantly associated with older foster care youth’s religious involvement. Hierarchical logistic regression analyses showed that religious service attendance was associated with reduced odds of youth’s engagement in sexual behavior in the past 2 months and current use of cigarettes. In addition, greater religious beliefs were associated with a reduction in odds of youth’s use of alcohol in the past 6 months and current use of cigarettes. The consideration of religious involvement as a positive influence and resource that may reduce unhealthy risk behaviors among older youth in foster care is discussed.  相似文献

This paper discusses the view that fantasizing, understood as a flight into fantasy, belongs to a type of mental functioning distinct from imaginative fantasy. From this the idea emerges, proposed by Winnicott, that withdrawal into fantasy assumes a dissociative quality, which is formed early on as a defensive solution following the loss of hope in object relations. Such a defence becomes the foundation for a dangerous enclave in which the individual ends up enclosing himself, experiencing an illusory self-sufficiency. In this perspective, the author maintains that the flight into fantasy must be understood as a risk factor for the draining of the self or for a crystallization into psychopathological structures, becoming an automatic activity of 'non-thought' that substitutes for the working-through processes necessary for the development of the mind. The paper investigates this psychopathological dynamic, which was already present in Breuer and Freud's writings, examining subsequent contributions of various authors. Clinical material (of both children and adults) illustrates how the flight into fantasy may take the form of an anti-relational realm of the mind, compromising the operations necessary to the integration of psychic life. There is also a discussion of which therapeutic tools may help the patient to gradually abandon the withdrawal in favour of an authentically nourishing relational nature.  相似文献

A cross-sectional study examined the relationship between three dimensions of the belief in a just world and the subjective well-being of Pakistani mothers of normal and Down syndrome children (n = 100 each). Personal belief in a just world and two dimensions of general belief in a just world-beliefs in immanent and ultimate justice-were assessed along with four dimensions of subjective well-being: life satisfaction, mood, state anxiety, and depression. It was hypothesized that personal belief in a just world and belief in ultimate justice would be positively associated with subjective well-being for both groups of mothers. Results were obtained through moderated regression analyses. In line with our hypothesis, personal belief in a just world positively predicted life satisfaction and mood level and negatively predicted state anxiety and depression in both groups of mothers. In contrast, beliefs in immanent and ultimate justice were not consistently adaptive. In particular, the more the mothers of a Down syndrome child believed in immanent justice, the more anxiety they experienced the previous week. In addition, the more the mothers of normal children believed in ultimate justice, the more they experienced anxiety. The pattern of results persisted when controlled for mothers' education, the total number of their children and marital status. Overall, the results support the role of personal belief in a just world as a personal resource in adverse as well as normal life circumstances.  相似文献

Research on the belief in a just world (BJW) has focused on its intra-individual functions (e.g., psychological well-being) and its inter-individual consequences (e.g., derogation of victims). Recent theorizing, however, has indicated that the BJW may also have more societal functions and consequences, serving as a legitimizing device of the status quo. The studies in the current paper focus on this latter view and are based on Alves and Correia's ( 2008 ) research which found that the expression of high personal and general belief in a just world is injunctively normative. Two experimental studies aimed at ascertaining three issues: (1) the dimension(s) of social value (social utility and/or social desirability) on which the BJW normativity anchors; (2) whether the expression of moderate BJW is also injunctively normative; and (3) whether the injunctive normativity of the BJW is related to perceptions of truth. Results indicate that moderate and high personal and general BJW are normative. Yet, whereas the normativity of personal BJW anchors both on social utility and social desirability, that of general BJW anchors only on social utility. We discuss personal and general BJW as judgement norms, whose normativity may not be personally acknowledged (in the case of general BJW) and does not necessarily derive from being perceived as true, but from the fact that such norms carry social value at least in individualistic societies.  相似文献

David Thorne's (2010) article, “The Identities Hidden In The Matching Laws, And Their Uses” performs a valuable service in pointing out alternative expressions of matching. However, some identities tend to obscure rather than illuminate empirical relationships. Three such problematic instances are discussed: interresponse time as a function of interval and ratio schedule parameters; probability equality as implying rate matching; the apparent simplicity of probabilistic functions, as opposed to response rate functions, of reinforcement rate.  相似文献

This paper addresses the question of what we can legitimately say about things in themselves in Kant's critical doctrine. Many Kant scholars believe that Kant allows that things in themselves can be characterized through the unschematized or ‘pure’ concepts of our understanding such as ‘substance’ or ‘causality’. However, I show that on Kant's view things in themselves do not conform to the unschematized categories (given their standard discursive meaning): the pure categories, like space and time, are merely subjective forms of finite, discursive cognition. I then examine what this interpretation might entail for central aspects of Kant's system such as his doctrine of noumenal freedom.  相似文献
