Women with a strong family history of breast and/or ovarian cancer can now have genetic testing, that may identify mutations associated with increased cancer predisposition. Within the context of a clinical trial evaluating printed educational materials, we examined motivation, satisfaction, coping, and perceptions of genetic counseling and testing among 159 women who underwent pretest counseling and made a testing decision. Ninety-six percent of the participants elected to have BRCA1/2 testing. When making a decision about genetic testing, study participants were concerned less about the potential negative effects that could result from testing than the potential benefits. After counseling, participants said that they felt better able to make decisions that were right for them and that their questions and concerns were adequately addressed during the session. Ninety-five percent of the women were satisfied with their test decision. Participants used a range of strategies to cope with thoughts and feelings about cancer and/or genetic testing immediately following test decision. Results suggest that the genetic counseling session helped women make decisions about testing for BRCA1 and BRCA2, even in the setting of a trial in which all women also received detailed educational materials. Further, the results indicate that future research focusing on perceptions of risks and benefits of testing and of coping strategies immediately following test decision may be warranted.  相似文献

A community sample of foreign-born first generation (n = 53) and U.S.-born secondgeneration (n = 57) youth of Indian origin (ages 18–25) was studied. Variables predicting self-critical perfectionism were perceived prejudice, enculturation, and communication difficulty with parents and their interaction with generation status. The differences between the two generations pointed to nuanced self-pressures of Indian immigrant youth, despite good academic standing and middle-class family income. Implications discuss counseling with Indian immigrant youth.  相似文献

The aggressive behaviour of free-ranging guanacos and vicuñas, living in sympatry in Catamarca Andes, Argentina, was analysed in relation to their social organisations. These organisations include territorial family units, solo males (territorial or not), and bachelor groups. In both guanacos and vicuñas, family groups tended to have higher rates of agonistic interactions than bachelors and to be frequently involved in aggressive encounters, whereas bachelor groups showed the opposite tendencies. Encounters between family groups and solo males were more frequent than expected. Bachelors acted almost exclusively as recipients of aggressive interactions, whereas solitary and family males frequently initiated encounters. Family groups adopted different behaviours towards bachelors in the two camelids. In guanacos, the latter were simply ignored, whereas in vicuñas (where they tend to compete for food with families) bachelors were consistently attacked by families. The behaviour of solitary males showed the main difference between the two species. Guanaco solo males had a much more aggressive attitude than vicuña counterparts. Their proportion in guanaco population was also unexpectedly high. These results suggest that, in the less rigid organisation of guanaco society, the behaviour of solitary males is adopted by a number of adult males in an attempt to breed. © 1996 Wiley-Liss, Inc.  相似文献

The brain dopaminergic system is involved in the process of long-term selection for reduced aggressive reaction towards man in Norway rats. The dopamine levels in the striatum as well as the nucleus accumbens with the tuberculum olfactorium were significantly lower in domesticated rats than in their wild counterparts. A substantial decrease was found in homovanillic acid level in the n. accumbens and tuberculum olfactorium. Specific binding of [3H]spiperone which labels D-2 dopamine receptors was higher in the mesolimbic structure of tame rats, whereas binding of [3H]SCH 23390 (D-1 receptors) was unchanged in this area. No substantial differences were detected in D-1 and D-2 binding in striatum. Apomorphine (0.3 mg/kg) elicited less locomotion in tame animals, reflecting a decrease of sensitivity of postsynaptic dopamine receptors. Tame rats showed fewer aggressive contacts in a foot-shock test than wild rats and the D-2 receptor antagonist sulpiride (25 mg/kg) significantly decreased the foot-shock aggression only in wild rats. Therefore, domestication, which diminishes defensive behavior and emotional reactivity of animals, is associated with decreases of dopamine level in the striatum, changed metabolism of dopamine in mesolimbic system, and an alteration in density and senstivity of D-2 receptors.  相似文献

Although family systems theory posits reciprocal causality between subsystems of the family, such as intimate partner violence exacerbating harsh parenting and vice versa, longitudinal studies with cross‐lagged models have been used infrequently to test these principles. As guided by the spillover model, this study examined bidirectional associations between couple dysfunction, parent–child aggression risk, and child functioning across the transition to parenthood to determine whether and how disruptions in one subsystem relate to problems in other family subsystems. Participants were 201 first‐time mothers and 151 fathers from a diverse community sample, evaluated during pregnancy, and reassessed two more times through their child's first 18 months of life. Individual and dyadic path model results indicate bidirectional spillover effects between parent–child aggression risk and child functioning for both mothers and fathers, and spillover from parent–child aggression risk to couple dysfunction for mothers but not fathers. However, limited spillover effects were identified between couple functioning and child adjustment, in contrast to previous work. Findings suggest that spillover can happen reciprocally and early in the family, supporting transactional models of behavior and highlighting the need for early family level intervention.  相似文献

Research suggests that parent–child conflict is a salient family process in Asian immigrant families and often a stressful experience for Asian American youth due to value discrepancies between Asian and Western cultures. The present study examined ratings of parent–child conflict across conflict topics from parents' and children's perspectives in a sample of Chinese American immigrant families with school‐age children (N = 239; age = 7.5–11 years). Latent profile analyses identified three parent‐rated conflict profiles and four child‐rated conflict profiles. Parent and child conflict profiles were unrelated to each other and differentially related to family sociocultural factors and children's psychological adjustment. Parents' moderate conflict profile scored highest on parent‐rated child behavior problems and had the highest household density and lower parent Chinese orientation. Children's moderate‐specific and high conflict profiles scored higher on child‐reported behavior problems than the low conflict profile. These results highlight the need to assess family conflict from both parents' and children's perspectives and target parent–child conflict communication as a pathway to prevent or reduce behavioral problems in Chinese American children of immigrant families.  相似文献

In recent years, same‐gender group‐based relationship education has emerged as a viable intervention to prevent relationship distress among same‐gender couples. However, many of these programs are conducted in metropolitan areas and lack the ability to reach rural populations. The current study sought to investigate whether two wide‐reaching web‐based heteronormative relationship education programs could positively impact same‐gender relationships. In a sample of 49 same‐gender couples, heteronormative relationship education had small (Cohen's d = 0.16–0.39) but reliably positive effects on key areas of relationship functioning and perceived stress relative to a waitlist control group. Additionally, when same‐gender couples were matched with different‐gender individuals with similar baseline characteristics, no reliable differences between the two groups emerged even though the program effects were sometimes half as large for same‐gender couples. Finally, same‐gender participants were as satisfied with the program as the matched different‐gender individuals. Though the results of the present study indicate that heteronormative relationship education can be helpful for same‐gender couples, additional tailoring should be undertaken to ensure that same‐gender couples experience as much benefit as possible. Estimates from the current study could be used in future studies to detect what might be small‐sized differences.  相似文献

Joint physical custody, a parental care arrangement in which a child lives with each parent about equally after separation or divorce, is an increasingly common phenomenon in many Western countries. Although attention from family scholars, practitioners, and law professionals is growing, there are hardly any numbers on the prevalence of joint physical custody (JPC). Moreover, studies using large‐scale representative data on the effects of JPC for children’s well‐being are still rare. The data for this study come from Health Behaviour in School‐Aged Children (HBSC), a representative cross‐national survey of adolescents in 37 European and North American countries that was conducted in 2002, 2006, and 2010 and included information on students at the ages of 11, 13, and 15 years (N = 92,886). First, results revealed that symmetrical JPC after family dissolution is still very rare in the majority of countries (5% or less), but reaches 10–20% in some countries. Second, adolescents’ life satisfaction in nonintact families is higher in symmetric JPC arrangements than in asymmetric care arrangements. However, after controlling for children and family characteristics, the differences disappear. Thus, it is not the symmetric JPC arrangement that induces adolescents’ higher life satisfaction, but rather the children and family characteristics that are associated with the choice of such a custody arrangement by separated or divorced parents.  相似文献

This study examined divorce attitudes and reasons for divorce in Iran, a nation experiencing a rapid increase in divorce. Using instruments translated into Farsi with a sample of 230 Iranian spouses filing for divorce, we found a preponderance of common relational reasons for divorce (such as growing apart and not getting enough attention), along with high rates of interpersonal violence reported by wives. Study participants showed considerable rates of divorce ambivalence, along with openness to reconciliation services. The findings were compared with similar studies of the United States spouses in the divorce process. Clinical implications include a careful approach to considering how discernment counseling might be adapted to the cultural situation of Iran, and particularly the special concerns of Iranian women.  相似文献
