Community interventions are complex social processes that need to move beyond single interventions and outcomes at individual levels of short-term change. A scientific paradigm is emerging that supports collaborative, multilevel, culturally situated community interventions aimed at creating sustainable community-level impact. This paradigm is rooted in a deep history of ecological and collaborative thinking across public health, psychology, anthropology, and other fields of social science. The new paradigm makes a number of primary assertions that affect conceptualization of health issues, intervention design, and intervention evaluation. To elaborate the paradigm and advance the science of community intervention, we offer suggestions for promoting a scientific agenda, developing collaborations among professionals and communities, and examining the culture of science.

Beginning with a social system perspective on the forms and functions of the junior high school and high school classroom, a Classroom Environment Scale (CES) was developed. The CES is a 90-item perceived environment scale that assesses nine dimensions (e.g., student involvement, competition) of the classroom. Intercorrelations among the subscales indicate that the CES measures distinct, though moderately correlated, aspects of the classroom environment. Each of the subscales significantly discriminates among the 38 classrooms in the current standardization sample, and internal consistency of the subscales and overall profile stability are high. Sample profiles of contrasting classrooms are described and compared, and the theoretical implications as well as the pragmatic utility of the CES are discussed.The conceptualization and assessment of human environments has recently assumed increased importance as an area of theoreti-

Community psychology has historically focused on understanding individual behavior in sociocultural context, assessing high-impact contexts, and working in and with communities to improve their resources and influence over their futures. This review adopts an ecological perspective on recent developments in the field, beginning with philosophy of science and progressing through a series of substantive research and intervention domains that characterize current work. These domains include research on the ecology of lives, the assessment of social settings and their impact on behavior, culture and diversity as expressed in the community research process, and community intervention.

The purpose of this paper is to apply an ecological perspective to the conduct of multilevel community-based culturally-situated interventions. After a discussion of the emerging consensus about the value of approaching such interventions ecologically, the paper outlines a series of questions stimulated by an ecological perspective that can guide further theory development in conducting multilevel interventions. These questions all derive from the importance of assessing the local community ecology where the intervention occurs. The paper concludes with a series of topics which, taken together, provide a roadmap for further conceptual development of multilevel interventions as vehicles for long-range community impact.

While a great deal of research has been conducted to understand acculturation and its relationship to adaptation in the new country, surprisingly little attention has been paid to the ways in which the characteristics of the local community impact these processes. The present study addresses this gap in the literature by exploring the potential role of community differences in the acculturation and adaptation processes of 269 refugee and immigrant adolescents from the former Soviet Union who resettled in two different community contexts. Specifically, a prior study on acculturation and adjustment among high school students (D. Birman, E. J. Trickett, & A. Vinokurov, 2002) was replicated with the same émigré population in a contrasting community within the same state. The contrast between these communities allowed us to test hypotheses emerging from an ecological perspective concerning (1) patterns of acculturation, (2) levels of discrimination and its effect on acculturative outcomes, and (3) community differences in the relationship between acculturation and outcomes. In addition to the focus on community differences, the study also employs a multidimensional measure of acculturation and assesses acculturation to both American and Russian culture. Furthermore, adaptation is assessed across different life domains; including peer relationships, family relationships, school adaptation, and psychological adaptation. Findings support the general ecological perspective, suggesting the importance of studying acculturation and adaptation as a reflexive process in which culture and context are very much intertwined.

This study explores how acculturation is related to adaptation across different life spheres for 162 Soviet Jewish refugee adolescents in a suburban community in Maryland. Because the different contexts of refugee adolescents' lives vary in acculturative demands, different patterns of acculturation should be related to adaptation in different life spheres. The study uses a multidimensional measure of acculturation and assesses acculturation to both American and Russian cultures as it relates to psychological adaptation, peer relations, and school and family outcomes. Findings support the general ecological thesis that acculturation to different cultures is differentially related to adaptation across life domains. Acculturation to American culture predicted better grades and perceived support from American peers. Acculturation to Russian culture predicted perceived support from Russian peers. Both American acculturation and Russian acculturation predicted reduced loneliness and perceived support from parents. Further, different dimensions of acculturation, such as language and identity, were differentially related to adaptation. Implications for acculturation theory and measurement are drawn, and cautions are offered about the interpretation of acculturation studies using single proxies such as language use or preference.
