The Program Environment Scale (PES) was developed for use with clients of community-based programs for the severely mentally ill. It is intended to fill the gap in available tools for assessing clients' perceptions of program functioning as it affects their quality of life in a program. Formal pretests were conducted with 121 clients at 12 randomly selected programs near Washington, DC. The final field test used a revised form (29 domains; 129 items) with 221 clients in 22 programs selected randomly throughout the U.S., including Clubhouse, day treatment, psychosocial rehabilitation, and social club programs. Twenty-three subscales met at least five of eight psychometric criteria for internal consistency and discriminant validity. A 24th subscale was retained because of its substantive importance. Successful subscales cover program atmosphere and interactions (program cares about me, energy level, friendliness, openness, staff-client and client-client respect, reasonable rules, availability of positive physical contact, protection from bad touch, staff investment in their jobs, and confidentiality), client empowerment/staff-client equality (program and treatment empowerment, egalitarian space use), and service components (support for paid work, work importance, emergency access, family activities, housing, public benefits, community activities, medications, substance abuse, and continuity). Subscale validity is indicated by associations of specific service offerings with scores on scales measuring client perceptions of those services, and by an ability to differentiate among program models (i.e., Clubhouses, day treatment programs, and psychosocial rehabilitation programs look different from each other). Subscale scores were not influenced by client characteristics (gender, race, age, diagnosis, number of hospitalizations, length of time in program). The final scale has 97 items and takes about 25 minutes to complete. The PES succeeds in measuring different aspects of programs as clients perceive them. In the programs we visited, directors felt the PES covers the important things they want to know about how clients perceive their program. The PES should become a useful tool both for researchers interested in how client responses to programs may influence their therapeutic outcomes, and for practitioners interested in improving their clients' program experiences and/or increasing convergence of staff and client views of their program.  相似文献

Evidence of the continuity of early problem behaviors in young girls and boys was examined developmentally. Data were gathered on 104 mother-child dyads from low-income families when children were between 1 and 5 years of age. Difficult temperament, aggression, and noncompliance from 12 to 24 months, and externalizing and internalizing problems at 36 and 60 months, were assessed. The results provide evidence for the continuity of early behavioral and emotional problems and support for the early differentiation between internalizing and externalizing problems. Implications of the current findings for prevention efforts are presented.  相似文献

Parents' perceptions of child development are influenced by complex interactions among cultural, social, and economic factors. Insights into how parents from culturally diverse societies perceive the development of their children might explain why different cultural groups foster or value the development of different skills in their children. In this study, we explored the perceptions of child development among low income Mexican American parents. A series of ethnographic interviews were conducted with eight Mexican American families who had preschool children. Qualitative data analyses yielded three main themes that were important to these parents: family attitudes and values, changes, and adaptations. For these parents, the development of social attributes in children, that will enable them to function within their own cultural group, was as important as the development of cognitive or motor skills. Service providers, such as school and mental health personnel, should take into account cultural differences in parents' perceptions of the importance of various developmental milestones for their children when suggesting interventions typically used by parents in the dominant culture.  相似文献

In their search for an authentic moral self, women and men may at some time in their lives assume a position of resistance. Men are most likely to assume this position in the sphere of war. It is not clear, however, where or when women would be expected to assume such a position or what the nature of that position might be, and how far it could be likened to that of the resisting man. This paper explores the idea that choosing to be a single mother can be a position by and from which women can voice their moral criticism. Such position is comparable to the (known and well-studied) position taken by men who show their moral criticism by refusing to participate in a specific battle during a morally controversial war. The paper begins with an examination of the philosophical and psychological concepts of separate and connected moral positions available to resisting men and women in the spheres of war and family. The conclusions are based on data from two samples of resisters in the spheres of war and the family: 36 soldiers (30 years old on average) who decided to take a stand as selective conscientious objectors (SCOs) during a morally controversial war and 50 (biologically) mature single women (over age 30) who chose to become pregnant and to remain unwed mothers. The conceptual and methodological questions regarding this comparison are discussed.  相似文献

This paper explores the concept of sustainable development and its ethical and public policy implications for engineering and multinational corporations. Sustainable development involves achieving objectives in three realms: ecological (sustainable scale), economic (efficient allocation) and social (just distribution). While movement toward a sustainable society is dependent upon satisfying all three objectives, questions of just distribution and other questions of equity are often left off the table or downplayed when engineers and corporate leaders consider sustainable development issues. Indeed, almost all the effort of engineers and engineering organizations on the issue of sustainable development has been focused on striking a balance between economic development and environmental protection. Similarly, corporate approaches rely on technological fixes to the challenges posed by sustainable development. While there have been some efforts aimed at incorporating environmental and social equity concepts into engineering codes of ethics, social concerns have been secondary to environmental issues. The incongruity between the ideal of sustainable development and the way in which it is typically characterized by the engineering and business communities has significant implications for engineering and public policy, engineering ethics, and the potential roles of engineers and multinational corporations as facilitators of a transition to a sustainable society. Presented at the Engineering Foundation Conference on “Ethics for Science and Engineering Based International Industries”, Durham, NC, USA, September 1997. An earlier version was presented at and appeared in the proceedings of the “1997 International Symposium on Technology and Society”, IEEE Society on Social Implications of Technology, Glasgow, Scotland, UK, June 1997. The author, an Assistant Prolessor of Multidisciplinary Studies, teaches in the Science, Technology and Society Program and is Director of the Benjamin Franklin Scholars Program, a dual-degree program in engineering and humanities/social sciences.  相似文献

Seventy-one families from a low socio-economic background, each with a son at risk of developing psychosocial problems at the onset of the study, were observed three times over a six-year period while solving a combinatorial task presented on a microcomputer. The permutations task was used to gather information with regard to cognitive functioning and cognitive self-regulation of the families, which were observed as a developmental unit. Cognitive functioning was assessed according to three variables: cognitive strategies, performance, and completion of the task. Six self-regulatory activities were assessed: task definition, planning, supervision, evaluation, parental support, and sharing of responsibilities. Although inefficient strategies were mainly used across the six years, the cognitive level of functioning improved over the years. Cognitive self-regulatory activities most often used across time were supervision and parental support. Differences were observed in the three time periods for supervision, task definition, parental support, and individual involvement. Results indicated a link between cognitive strategies used by the families to solve the task and their self-regulatory activities. Results are interpreted within both the Piagetian and Vygotskian perspectives. Families' cognitive self-regulatory activities observed in this study are an example of parental disengagement and children's growing involvement in a joint activity.  相似文献

The costs of disconnection between the basic and applied sectors of behavior analysis are reviewed, and some solutions to these problems are proposed. Central to these solutions are collaborations between basic and applied behavioral scientists in programmatic research that addresses the behavioral basis and solution of human behavior problems. This kind of collaboration parallels the deliberate interactions between basic and applied researchers that have proven to be so profitable in other scientific fields, such as medicine. Basic research questions of particular relevance to the development of behavioral technologies are posed in the following areas: response allocation, resistance to change, countercontrol, formation and differentiation/discrimination of stimulus and response classes, analysis of low-rate behavior, and rule-governed behavior. Three interrelated strategies to build connections between the basic and applied analysis of behavior are identified: (a) the development of nonhuman animal models of human behavior problems using operations that parallel plausible human circumstances, (b) replication of the modeled relations with human subjects in the operant laboratory, and (c) tests of the generality of the model with actual human problems in natural settings.  相似文献
