The authors review the recent empirical and theoretical literature on physician-assisted dying (PAD) since implementation of the Oregon Death With Dignity Act (ODDA) in 1997. The authors provide a brief overview of end-of-life practices; consider ethical and practical issues regarding PAD; outline governments' acts and health care organizations' current codified principles regarding PAD, including the American Psychological Association's goal to increase the visibility of psychology in end-of-life issues; examine recent data pertinent to ODDA implementation and psychologists' attitudes regarding PAD; and outline potential roles for health psychologists responding to requests for PAD and implementing PAD (where it is legal). Health psychologists can assume at least 4 roles regarding PAD: (a) policy advocates, (b) educators, (c) practitioners, and (d) researchers.  相似文献

While previous research has mainly emphasised the importance of leader–member exchange (LMX) to job satisfaction, there is a lack of research on reciprocal relationships between job satisfaction and LMX. In this study, we not only suggest that good LMX increases job satisfaction, but that job satisfaction can also enhance high‐quality supervisor–employee relationships. A full cross‐lagged panel analysis was used to test reciprocal relationships between LMX and job satisfaction. Employees (N= 279) of a large information technology company filled out questionnaires at two times, with a time lag of 3 months. In line with our predictions, findings revealed a positive relationship between LMX and job satisfaction both at Time 1 and Time 2. Moreover, LMX at Time 1 predicted the increase of job satisfaction at Time 2, and job satisfaction at Time 1 predicted the increase of LMX at Time 2. The results demonstrate the need to consider reciprocal relationships between job satisfaction and LMX when explaining employees' workplace outcomes. Our findings are discussed in terms of positive psychology theory.  相似文献

The positive link between attitude similarity and attraction is one of the fundamental outcomes in social psychology. However, attitude dissimilarity seems to be a stronger driver of this relationship than attitude similarity. The authors review the evidence on this similarity–dissimilarity asymmetry, and discuss two explanations. One is that people generally enter into interactions with optimism, and so supposedly neutral partners are often seen as mildly positive. Another is that dissimilar attitudes carry greater weight than similar attitudes in cognitive processes. Implications of these mechanisms for wider issues in person perception and attitude structure are discussed, connecting them with more recent theories of attitudinal ambivalence and evaluative space.  相似文献
