Self-objectification (Fredrickson and Roberts 1997) has been related to negative psychological consequences in U.S. women. However, little cross-cultural research has been done. We compared convenience samples of American and Nepali women on two measures of self-objectification. Pairs of Nepali mothers and daughters (N?=?23) and pairs of U.S. mothers and daughters (N?=?24) completed a quantitative and a qualitative measure of self-objectification. Cultural and generational differences were found. Nepali women engaged in less self-surveillance than U.S. women. Older women engaged in less self-surveillance than younger women. Women in both cultures had high beliefs in their ability to control the body. An additional dimension of body consciousness, termed Functionality, was particularly important to younger Nepali women.  相似文献

Five adoption‐reconstruction phases were identified in narratives of 100 adoptees ages 35 to 55 years. Phases ranged from no awareness of adoption issues (Phase 1) to acute awareness accompanied by anger, resentment, and sadness about adoption (Phase 3) to a sense of peace and acceptance (Phase 5). Consistent quantitative and qualitative differences were found among adoptees at the 5 phases on multiple measures of functioning.  相似文献

Psychological defense mechanisms are a powerful and often unappreciated force safeguarding mental health. Although rarely directed in this way, the most common forms of psychiatric treatment—psychotherapy and antidepressants—can enhance psychological defense mechanisms. Psychotherapy, through both specific and nonspecific factors, induces positive perspective shifts favoring positive cognitive distortions, including adaptive classical defense mechanisms and healthy attribution biases. Antidepressants, by altering very basic emotional information processing, such as facial expression recognition and emotional memories, also foster positive cognitive distortions. By shifting perceptions and thoughts in a positive direction, psychotherapy and antidepressants improve the capacity to dissociate from negative emotional stimuli.Brad Bowins, M.D., FRCP(C), is a staff psychiatrist at the University of Toronto Health Service and he is in private practice.  相似文献

Although authors are usually considered to be the main perpetrators of research and publication misconduct, any person involved in the process has the potential to offend. Editors may breach ethical standards particularly with respect to conflicts of interest. In the same way that authors are now required to declare competing interests, notably commercial affiliations, financial interests and personal connections, so must editors. Editors can influence the chances of acceptance or rejection of a paper by reviewer selection. Reviewers should also be ready to disclose conflicts of interest. They must ensure that their reviews are evidence based and free from destructive criticism driven by self interest. It seems likely that ultimately we will progressively move towards 'open' peer review in which both the authors and the reviewers are known to each other. There is an urgent need for increased transparency of the relationship between editors and owners. The events of the last few years indicate that unless this interface is fully understood by all parties, conflicts may arise. There is also a need for a radical overhaul in the relationship between journals, journal editors and the biomedical industry. It is now increasingly accepted that all clinical trials should be registered in a centrally held database and that protocols should include the primary and secondary outcome measures and the intended approach to data analysis thereby avoiding opportunistic post hoc analyses. However, the even more radical proposal that journals should cease to publish clinical trials sponsored by industry deserves wider debate.  相似文献

Innocent suspects interviewed by a guilt‐presumptive versus innocence‐presumptive or neutral interviewer may tend more to display non‐verbal behaviours which neutral judges consider indicative of guilt. We examined the effects of interviewer's presumption of guilt on innocent mock suspects' alibis. Participants (N = 90) provided an alibi to convince an interviewer of their innocence of a theft after she implied that she believed that they were guilty or innocent or that she had no belief about their veracity. On the basis of existing conflicting findings for suspects' verbal behaviour during accusatory interviews, we predicted that alibis in the guilt‐belief condition would contain the highest or lowest number of correct details with overall higher or poorer accuracy rates, respectively. Although participants perceived the interviewer's presumptive approach, the number of correct details provided and accuracy rates of alibis did not differ significantly between conditions. We propose explanations to these findings and future research paths.  相似文献

Researchers have documented that vacant lot greening can reduce community-level crime and violence. Busy Streets Theory (BST) suggests that residents who are involved in the greening process can help to improve physical environments and build social connections that deter crime and violence. Yet few researchers have explored how community engagement in the greening process may affect crime and violence outcomes. We applied BST to test the effects of community-engaged vacant lot greening compared to vacant lots that received either professional mowing or no treatment, on the density of violent crime around study lots. Using mixed effects regression models, we analyzed trends in violent crime density over the summer months from 2016 to 2018 at 2102 street segments in Youngstown, OH. These street segments fell within 150 meters of an intervention parcel that was classified as one of three conditions: community-engaged maintenance, professional mowing, or no treatment (control). We found that street segments in areas receiving community-engaged maintenance or professional mowing experienced greater declines in violent crime density than street segments in areas receiving no treatment, and more decline occurred in the community-engaged condition compared to the professional mow condition. Our findings support BST and suggest that community-engaged greening of vacant lots in postindustrial cities with a concentrated vacancy can reduce crime and violence.  相似文献

We established a general genetic counseling clinic (GCC) to help reduce long wait times for new patient appointments and to enhance services for a subset of patients. Genetic counselors, who are licensed in Tennessee, were the primary providers and MD geneticists served as medical advisors. This article describes the clinic referral sources, reasons for referral and patient dispositions following their GCC visit(s). We obtained patients by triaging referrals made to our medical genetics division. Over 24 months, our GCC provided timely visits for 321 patients, allowing the MD geneticists to focus on patients needing a clinical exam and/or complex medical management. Following their GCC visit(s), over 80 % of patients did not need additional appointments with an MD geneticist. The GCC allowed the genetic counselor to spend more time with patients than is possible in our traditional medical genetics clinic. Patient satisfaction surveys (n?=?30) were very positive overall concerning the care provided. Added benefits for the genetic counselors were increased professional responsibility, autonomy and visibility as health care providers. We conclude that genetic counselors are accepted as health care providers by patients and referring providers for a subset of clinical genetics cases. A GCC can expand genetic services, complement more traditional genetic clinic models and utilize the strengths of the genetic counselor health care provider.  相似文献

The role of psychological pain in the risk of suicide was explored using a three‐dimensional psychological pain model (pain arousal, painful feelings, pain avoidance). The sample consisted of 111 outpatients with major depressive episodes, including 28 individuals with suicidal histories. They completed the Chinese version of the Beck Scale for Suicide Ideation (BSI), the Beck Depression Inventory (BDI), the Psychache Scale, and the three‐dimensional Psychological Pain Scale (TDPPS). A structured clinical interview was conducted to assess the history of suicidal acts. Significant correlations were found among BDI, BSI, and TDPPS scores (p < .01). Stepwise regression analyses showed that only pain avoidance scores significantly predicted suicide ideation at one's worst point (β = .79, p < .001) and suicidal acts (β = .46, p < .001). Pain avoidance was also a better predictor of current suicidal ideation (β = .37, p = .001) than were BDI scores (β = .31, p < .01). Increased levels of pain avoidance during a major depressive episode may be a dominant component of the motivation for suicide. Future clinical assessments for populations at high risk of suicide should include measures of psychological pain to reduce the incidence of suicide.  相似文献
