Theory and research have not kept pace with the growing interest in evaluating quality of mental health care, resulting in the use of unvalidated quality indicators. A framework for validating quality indicators is offered by which quality is viewed as the relationship between service structures, processes, and outcomes. Adoption of this framework will facilitate the measurement of quality using valid indicators and should be useful to agencies in their continuous quality improvement efforts. Valid information about the quality of mental health care services will help purchasers and consumers make more informed health care decisions.  相似文献

Little documentation exists regarding the functioning of formalized adolescent groups as drug abuse prevention agents. Two studies are described that were conducted at high schools whose students are at high risk for drug abuse. Twenty-one schools were randomly assigned to one of three conditions: (a) standard care, (b) classroom drug abuse education only, or (c) classroom plus school-as-community. Results of the first study indicated that the school-as-community component--which involved weekly meetings and periodic events at seven schools--was implemented as planned, drug abused focused, and perceived as productive in discouraging drug abuse. In the second study, staff in the classroom plus school-as-community condition self-reported involvement in the greatest number of community activities across the school year, compared with staff from the other two conditions. These two studies support the feasibility of formalized groups of high-risk youth to promote drug-free events.  相似文献

US theoretical models of assimilation of ethnic groups within a larger culture usually assume a unilinear, unidimensional process, which is simplistic, does not account for the persistence of ethnicity, and oversimplifies the process of social change. The argument is advanced that ethnic identity is both primordial and situational (a private sense that is self-maintaining, cumulative, deepening, and self-affirming). Typically, a person has one primary ethnic identity, but where ethnic boundaries overlap, there is instrumental identity. Chinese in Thailand mostly adopt Thai values, speak the Thai language, go to Thai schools, join Thai associations, and celebrate Thai religious festivals. Their secondary identity as Chinese is integrated into their associations with other Chinese and in the home through the use of the Chinese language. Their Chinese identity appears also in ancestor worship. There are symbiotic relationships between native Thais and Chinese Thais along class lines. The Chinese are known to have great financial and economic resources, while the Thais have political and administrative control. These differences with the power elites separate the Chinese from the Thais and interfere with assimilation. The power is balanced. If the Chinese gained in political and administrative power, the balance would be upset, and the interests of both groups would be threatened. The view of Whitten and Whitten acknowledges that individuals and groups act to make the best of the situation and are not merely victims of social forces. Actions are maintained and resisted. The important consideration in theory-building is not the terms of assimilation but the terms specifying the conduct of the group as a whole and as individuals in daily social interactions. The theoretical discussion focuses on border crossings, the Skinner view of the Chinese, bilingualism and cultural education, socioeconomic organizations, occupational differences, and religion, tradition, and ethnic identification.  相似文献

"Life expectancy and mortality increasingly are analyzed in the context of social factors. This study analyzes the impact of social position, marital status, and religious confession on cohort life expectancy. The analysis is based on [German data from the] Socio-Economic Panel Survey, wherein proxy-interviewee's parents have been used to estimate cohort mortality. Results confirm a lower mortality risk of the upper classes and of married persons. However, as opposed to other studies, Catholics do not have a lower, but even a higher mortality risk."

Abstract As fertility comes increasingly under voluntary control in a developing society, it can be argued that individual desires or preferences about children will become more salient and more significant for eventual fertility. Hence, the study of preferences is increasingly important as contraceptive use is extended and results in decreasing the number of unwanted births.(1) Further changes in fertility then depend on changes in preferences. The assumption is that people will at least try to achieve the families they want, if the means to do so are available. The fact that contraception is used at all is some evidence of the soundness of this assumption, although it should be recognized that family size desires operate in a complex of preferences, under varying degrees of conflict and control. To expect a one-to-one relationship between attitudes or preferences and overt behaviour would be simplistic.  相似文献
