Evaluation design for a community prevention trial. An environmental approach to reduce alcohol-involved trauma

The Community Prevention Trial was 5-year effort to reduce alcohol-involved injuries and death through a comprehensive program of community awareness and policy activities. The three experimental communities were of approximately 100,000 population each (one in Northern California, one in Southern California, and one in South Carolina). Matched comparison communities were used for each experimental community. This article describes the evaluation approach used in a program that sought to change environmental factors not a specific population or target group. This approach demanded unique evaluation approaches for determining overall community aggregate effects, that is, distal outcomes, as well as changes in key mediating variables, that is, process effects. The problem of trending and lagged effects of community prevention programs are discussed.     

Summing up. Recommendations and experiences for evaluation of community-level prevention programs

This article provides recommendations and observations about evaluation of a locally based prevention project to reduce problems at a total community or aggregate level. The shift from targeting specific individuals or subpopulations to the overall structure and environment of a community is most demanding. Evaluation tools and analysis techniques have lagged behind program development because community-level interventions are not linked to a specific target group who can be separately studied. Thus assumptions about using random assignment and/or comparison communities as means to control for confounding variables are weakened when the unit of analysis is the community itself and dependent measures are subject to trending and the effects of history.     

An evaluation of retail outlets as part of a community prevention trial to reduce sales of harmful legal products to youth

Communities across the nation have become increasingly concerned about inhalant use and use of harmful legal products among youth because of increasing prevalence rates and deleterious health consequences from abusing these products. The increasing concern of communities about inhaling and ingesting legal products has been coupled with increasing awareness and concern about ability of youth to access and abuse a variety of other legal retail products. There are few examples of scientifically designed community prevention projects that seek to reduce youth abuse of such legal products. This article describes a community prevention trial that is designed to reduce sales of inhalants and other harmful legal products to youth and demonstrates how the retailer component of the trial can be rigorously evaluated. It also shows how data from youth purchase attempts can complement survey data from retailers.     

In Algeria: Pierre Bourdieu's photographic fieldwork

Today Pierre Bourdieu is well known as one of the most important social scientists of the 20^th century. One of the outstanding qualities of his work has been his innovative combination of different methods and research strategies as well as his analytical skills in interpreting the obtained data (his 'sociological gaze'). In this paper, we attempt to retrace the development of an extraordinary way of doing social research and show the benefit of Bourdieu's visual sociology for his empirical fieldwork and sociological theory. The article particularly stresses the significance of his photographic archive, which has long been ignored within the appreciation of Bourdieu's work. Studying Bourdieu's photography gives access to his œuvre in several new ways: not only can we understand how Bourdieu became an unconventional sociologist practicing his craft in the midst of a colonial war. Bourdieu's visual anthropology also offers an insight into the status nascendi of Bourdieu's sociology in all its elementary forms and contents. Through his photography Boudieu demonstrated the concepts of ' habitat and habitus ', the material and symbolic living conditions of the Algerian population.

Developing Survey Measures of Inequality of Autonomy in the UK

This paper explores the development of survey questions to measure autonomy, interpreted as the degree of choice and control a person has in key areas of his or her life. A review of the theoretical literature leads to a conceptualisation of autonomy as consisting of three components: (1) self-reflection, (2) active or delegated decision-making, and (3) a wide variety of high-quality options. Three major barriers to autonomy are identified: (1) conditioned expectations, (2) coercion, and (3) structural constraints, including lack of advice and support. A suite of questions designed to assess these components and barriers was devised and subjected to cognitive testing with a purposive sample of 34 individuals with diverse characteristics. The tests resulted in refinements to the language, response categories and phrasing of questions. Analysis of responses indicated that issues of decision-making and range and quality of options were easier for respondents to grasp than questions about self-reflection, and conditioned expectations could be detected only indirectly. Nevertheless the components of, and barriers to, autonomy could be separately identified. The article concludes that despite limitations, survey measurement of the complex concept of autonomy is possible and revealing.     

A general causal model to guide alcohol, tobacco, and illicit drug prevention: assessing the research evidence

The problems associated with the use of alcohol, tobacco, and other drugs (ATOD) extract a significant health, social, and economic toll on American society. While the field of substance abuse prevention has made great strides during the past decade, two major challenges remain. First, the field has been disorganized and fragmented with respect to its research and prevention practices; that is, there are often separate ATOD prevention "specialists." Second, both the prevention researchers who test the efficacy of specific prevention strategies and the practitioners who implement prevention efforts often lack an overall perspective to guide strategy selection. To address these limitations, we present an ATOD causal model that seeks to identify those variables (Domains) that are theoretically salient and empirically connected across alcohol, tobacco, and illicit drugs. For the researcher, the model demonstrates important commonalities, as well as gaps, in the literature. For the practitioner, the model is a means to recognize both the complexity of the community system that produces ATOD problems and the multiple intervention points that are possible within this system. Researchers and practitioners are thus challenged to work synergistically to find effective and cost-effective approaches to change or reduce ATOD use and associated problems.     

Community mobilization, organizing, and media advocacy. A discussion of methodological issues

Community Mobilization refers to those activities that prepare communities to accept, receive, and support prevention interventions designed to reduce alcohol-involved trauma. Media advocacy refers to the strategic use of media by those seeking to advance a social or public policy initiative. Within the Community Prevention Trial, both of these activities were critical elements. This article presents the evaluation design for community mobilization and media advocacy implemented for the project. Here the authors argue for the need to include both structured and unstructured community monitoring instruments, coding of local alcohol-related news coverage, and surveying community members about the exposure to alcohol-related problems, and support for project interventions. This article also presents an audience segmentation analysis and discusses the implications of this analysis for media advocacy efforts.
