Paternalism in family caregiving may jeopardize the older persons' autonomy; it needs to be better understood. Study objectives were to determine the relationship of belief in paternalism to personal-social characteristics and to determine the relative importance of these variables as predictors of belief in paternalism. Forty-six pairs of daughters (age 49.7) and mothers (age 77.7) were measured on belief in paternalism, dogmatism, attitude toward elders, affective feelings toward the other, and background and caregiving variables. Among both mothers and daughters, dogmatism and attitude toward elders were related to belief in paternalism; daughters' affective feelings was also related. Caregiving variables were unrelated, and demographic background was important only for daughters. Attitude toward elders was the strongest predictor. Results were interpreted in terms of a traditional family ideology.  相似文献

The goal of the research was to compare decisions under risk in a situation in which forecasters (F) communicate to decision makers (DM) either numerically (e.g., .70) or verbally (e.g., likely) about the chances that a binary event will occur. Following each forecast, the DM bid for a winning or losing lottery based on the event. In Experiment 1 Fs and DMs also provided numerical translations of each verbal forecast after the DMs' bid. In Experiment 2 the DMs provided membership functions over the [0, 1] interval for each phrase used by the Fs. The primary results were: (a) extreme similarity in the DM's bids and rates of bidding under the two modes of communication; (b) greater variability in bids to specific verbal than numerical forecasts; (c) a pattern of bids, in which DMs demonstrated risk seeking for gains and risk neutrality for losses; (d) DMs' numerical translations in Experiment 1 were closer to .50 than were those of Fs; and (e) phrases selected by Fs had high membership values to DMs for the probabilities the Fs were attempting to describe. Points (a), (b), (d), and (e) are consistent with the ν-μ model which assumes that the vague meaning of a probability phrase can be represented by a membership function over the [0, 1] interval, and that in reaching a decision the DM focuses on a range of probabilities with sufficiently high membership. Point (c) is speculatively attributed to social aspects of the dyadic situation, and requires further investigation.  相似文献

Psychotherapy research should ultimately benefit the psychotherapy client. Unfortunately, traditional psychotherapy research continues to have little influence on practicing clinicians and, therefore, does not benefit psychotherapy clients. As behavior analysts begin to show interest in this area of research, they may be in a position to improve its quality. We argue that traditional psychotherapy researchers have become prematurely wedded to a methodology that does not address the concerns of clinical audiences. Furthermore, we make a case for defining and evaluating psychotherapy data in terms of its capacity to influence both researchers and clinicians. We also suggest several alternative methods for gathering psychotherapy data based on the case formulation approach. We argue that this approach may be one of the most promising methods for gathering useful psychotherapy data.  相似文献

This article asserts that the family therapy field is approaching an epistemological shift from structuralism and positivism to postmodernism and relativism. The confluence of these movements: feminism, constructivism/constructionism, and cultural relativism is cited as a major impetus for the shift. Live supervision is examined within the context of this transformation, with a discussion of implications for the future.  相似文献

In recent years the developmental implications of menarche have garnered particular attention. Investigators have determined that this developmental event tends to affect three significant domains of the adolescent girl's function: psychological status, relationships with peers, and role in the family. This paper explores these issues and introduces a new technique, referred to as previewing, that may help the teenage girl acclimate to the status of sexual maturity. Derived from the early life interactions of caregiver and infant, previewing promotes representational skills and enhances self-esteem as the adolescent confronts developmental challenges.  相似文献

In the mid 1980s it was apparent that the need for organ donors exceeded those willing to donate. Some University of Pittsburgh Medical Center (UPMC) physicians initiated discussion of possible new organ donor categories including individuals pronounced dead by traditional cardiac criteria. However, they reached no conclusion and dropped the discussion. In the late 1980s and the early 1990s, four cases arose in which dying patients or their families requested organ donation following the elective removal of mechanical ventilation. Controversy surrounding these cases precipitated open discussion of the use of organ donors pronounced dead on the basis of cardiac criteria. Prolonged deliberations by many committees in the absence of precedent ultimately resulted in what is, to our knowledge, the country's first policy for organ donation following elective removal of life support. The policy is intricate and conservative. Care was taken to include as many interested parties as possible in an effort to achieve representative and broad based support. This paper describes the development of the UPMC policy on non-heart-beating organ donation.  相似文献
