Marital relationships, like individuals, follow a developmental trajectory over time with ups and downs and gains and losses. We work from a life course perspective and use growth curve analysis to look at trajectories of change in marital quality over time. Although the tendency is for marital quality to decline over time, some groups begin with much higher levels of marital quality than others. Moreover, a number of life course and contextual factors can accelerate or slow this path of change. Our findings point to the importance of considering the multi-dimensionality of time (e.g., age, marital duration, the passage of years) as well as family transitions (e.g., having children, emptying or refilling the nest) in creating the meanings and experiences of marriage over time. 相似文献

Although a large body of research demonstrates that the family has a powerful influence on physical health, the evidence for the effectiveness of family interventions in physical illness is less conclusive. Family therapy and other family interventions appear to be most effective in chronic childhood illnesses such as asthma and diabetes. Family interventions have also been shown to be effective in the management of some cardiovascular and neurologic disorders and for the treatment of obesity. Family therapy appears to be more effective than individual therapy for some groups of patients with anorexia nervosa. This research supports the increasingly important role of medical family therapy in the new health care system. Recommendations for future research are discussed. 相似文献

Donald T. Campbell 《Evaluation and program planning》1979,2(1):67-90
It is a special characteristic of all modern societies that we consciously decide on and plan projects designed to improve our social systems. It is our universal predicament that our projects do not always have their intended effects. Very probably we all share in the experience that often we cannot tell whether the project had any impact at all, so complex is the flux of historical changes that would have been going on anyway, and so many are the other projects that might be expected to modify the same indicators.It seems inevitable that in most countries this common set of problems, combined with the obvious relevance of social science research procedures, will have generated a methodology and methodological specialists focused on the problem of assessing the impact of planned social change. It is an assumption if this paper that, in spite of differences in the forms of government and approaches to social planning and problem-solving, much of this methodology can be usefully shared — that social project evaluation methodology is one of the fields of science that has enough universality to make scientific sharing mutually beneficial. As a part of this sharing, this paper reports on program impact assessment methodology as it is developing in the United States today. 相似文献
