Summary. When evaluating potential interventions for cancer prevention, it is necessary to compare benefits and harms. With new study designs, new statistical approaches may be needed to facilitate this comparison. A case in point arose in a proposed genetic substudy of a randomized trial of tamoxifen versus placebo in asymptomatic women who were at high risk for breast cancer. Although the randomized trial showed that tamoxifen substantially reduced the risk of breast cancer, the harms from tamoxifen were serious and some were life threaten-ing. In hopes of finding a subset of women with inherited risk genes who derive greater bene-fits from tamoxifen, we proposed a nested case–control study to test some trial subjects for various genes and new statistical methods to extrapolate benefits and harms to the general population. An important design question is whether or not the study should target common low penetrance genes. Our calculations show that useful results are only likely with rare high penetrance genes. 相似文献

This paper, the third in a series concerned with family therapy in cases involving children at risk of abuse, describes an approach to maximising parents' interest and commitment to therapy. After overviewing the difficulties faced by therapists in working with parents who are notorious for their ‘resistance’, we provide guidelines for minimising the negative consequences of notification and for constructing therapeutic leverage in order to elicit and maintain parents' motivation throughout the course of therapy. 相似文献

The Sandwich Generation: Dependency, Proximity, and Task Assistance Needs of Parents 总被引:2,自引:1,他引:1
This study was designed to determine the extent of sandwiched families and the impact of dependency and proximity to task assistance provided to parent(s). Data were collected in Idaho, Oregon, Utah, and Michigan from a random sample of 40–65-year-old respondents. Fifteen percent are sandwiched between needs of aging parents and financially dependent children. Respondents are much more likely to be providing assistance to mothers than fathers. Parents are most likely to live near, but not necessarily with, the respondent. Spouses and partners' parents, however, are likely to live farther away. Task assistance provided most often to aging parent(s) includes help with transportation and shopping; financial assistance was reported least often. Income of respondent and dependency and proximity of parents are significantly related to providing assistance to parents. This study offers a unique glimpse at the relationships between personal characteristics, dependency, proximity, and task assistance issues as they pertain to the sandwich generation. 相似文献

The paper describes the group therapy model which has evolved over the past two years on the Child Psychiatry Inpatient Unit of North Carolina Memorial Hospital. It begins with a brief review of the literature concerning group therapy with latency-aged children. The setting and patient population are described. Vignettes from group sessions are used to illustrate techniques which have evolved to deal with this particular setting and population. These include a leadership style characterized by much clarification, modeling, and limit setting; extensive focus on beginning and terminating; clearly defined behavioral limits; the use of time out; and use of play materials requiring little skill or attention as anxiety binders as well as projective media; and observation and supervisory discussions open to all members of the treatment team. The paper concludes with a discussion of the potentials and limitations of group therapy in such a setting. The thesis is that this model is effective in diagnosing developmental levels, in developing interpersonal skills, in substituting verbalization for action, and in mastering separation anxieties, though the setting limits the extent to which controlled regression, transference, and group pressures can develop and be used to produce change. 相似文献

Women's fear of violence can impact negatively on their active participation in life. An ageing survey conducted with 2,620 Australian respondents aged 50 to 90 years examined aspects of work, learning, social, spiritual and emotional status, health, vision, home, life events, demographics, and asked an open-ended question about what being actively engaged in life meant. Ordinal regression was carried out on two dependent variables: wanting and needing to learn to discourage violence. Analyses found that as women's age increased, those on lower incomes were more likely than others to say they needed to learn how to discourage violence against them. This paper investigates the variables associated with the findings-transport, finances, news media, home safety, and reduced social interactions. Results highlight the importance of understanding women's fear in the context of personal and social issues, and the need to provide learning opportunities to improve safety and social engagement. 相似文献

Efforts to improve child survival in lower-income countries typically focus on fundamental factors such as economic resources and infrastructure provision, even though research from post-industrial countries confirms that family instability has important health consequences. We tested the association between maternal union instability and children’s mortality risk in Africa, Latin America and the Caribbean, and Asia using children’s actual experience of mortality (discrete-time probit hazard models) as well as their experience of untreated morbidity (probit regression). Children of divorced/separated mothers experience compromised survival chances, but children of mothers who have never been in a union generally do not. Among children of partnered women, those whose mothers have experienced prior union transitions have a higher mortality risk. Targeting children of mothers who have experienced union instability—regardless of current union status—may augment ongoing efforts to reduce childhood mortality, especially in Africa and Latin America where union transitions are common. 相似文献
