Disseminating science-based prevention: lessons learned from CSAP's CAPTs

A wide variety of prevention approaches that reduce substance use and associated problems have been developed and tested. But successes have been limited in promoting the use of these scientific advances by the policy makers, practitioners, and concerned citizens. The Center for Substance Abuse Prevention's six regional Centers for the Application of Prevention Technologies (CSAP's CAPTs) are a major mechanism by which CSAP brings research to practice. This article synthesizes the issues that the CAPTs have faced, the solutions they have developed, and conclusions concerning the work that still needs to be done to increase the application of science-based approaches to prevention. These discussions highlight the particular importance of addressing issues related to the larger systems in which prevention programs and strategies operate.     

A method for combining sample survey data and symptomatic indicators to obtain population estimates for local areas

Past efforts of statistical demographers to compute postcensal population estimates for local units have been hampered by the fact that they have had to rely completely on symptomatic information. In this paper, a new method of postcensal estimation is presented in which the symptomatic information is combined with sample data by means of a regression format. Combining symptomatic information on births, deaths, and school enrollment with sample data from the Current Population Survey, county estimates of population growth were computed by means of the new method for the postcensal period after 1960. These estimates were tested for accuracy by comparison with a set of special censuses which were conducted between 1964 and 1967 in 75 counties. The results of this test are promising, but not conclusive. A more conclusive test is currently underway using 1970 data. While the method has been tested as a means for estimating population growth, it is to be emphasized that it can be used to compute postcensal estimates for any variable for which the necessary symptomatic information and sample data are available.     

Infant mortality decline in Chile: A replication

This replication of a previous analysis of the effect of sociological variables on infant mortality rates in Chile refines the earlier work by using the more numerous communes for comparisons, by presenting the basic data in the form of a path analysis, and by expanding the theory to include “health practices,” customs, such as avoiding teenage pregnancies, that are community-backed and maintained. This type of practice is then integrated into the “institutionalized problem-solving capacity” framework that guides the analysis. Urabnization and voting, the two indicators of institutionalized problem-solving capacity, predict reduced infant morality, as before. Teen pregnancies is a positive predictor, as expected, but the number of children already born does not predict. These results are net of two indicators of health technology-whether or not a physician was in attendance, and the number of clinics. Mother's education also predicted low infant morality, and the theory is applied to this well-known predictor to interpret its effect. In addition, the anomalous role of mother's education in the dominant biomedical explanation is highlighted.     

Race,SES Contexts and Fulfillment of College Aspirations*

The differential effects of social contexts and race on educational behavior are examined in terms of a causal process model. Based on data from San Diego, the role of social contexts are found to be important through a causal process in which SES contexts affect personal characteristics which, in turn, influence educational aspirations and attainment. Utilizing both correlational and tabular techniques, the basic model holds for all racial (ethnic) groups; however, race does affect the level of the individual variables. The findings from this study suggest that the importance of SES contexts are mediated by race and contingent upon the common relations of these contexts and educational behavior to individual characteristics.     

Bridging Environmental Science with Environmental Policy: Plasticity of Population, Affluence, and Technology

Objective . Sound environmental policy is fully dependent upon sound science. However, we have little scientific knowledge of the driving forces behind environmental change. We use the well-known I = PAT formulation (environmental i mpacts are the multiplicative product of p opulation, a ffluence, and t echnology) as a framework to assess the relative impacts of driving forces. Methods . We introduce the concept of plasticity —the potential for each factor to vary, particularly because of purposive human action (e.g., policy)—to fine tune our understanding of how each factor can influence different impacts. We illustrate plasticity by assessing each driving force for a variety of environmental impacts. Results . We demonstrate that population, affluence, and technology have different potentials for mitigating different types of impacts and that no one factor is of greater importance than the others. Conclusions . We conclude that plasticity measures can guide policymakers toward identifying and prioritizing those environmental problems most responsive to policy solution.     

Personnel Selection Procedures and Invasion of Privacy

We conducted two studies on the perceived invasiveness of 12 personnel selection procedures. In Study 1, indirect scaling methods were used to examine the degree to which 84 employed adults in the United States perceived such procedures to be invasive of privacy. Results showed the application blank was the least invasive of privacy and the lie detector was the most invasive of privacy. In Study 2, data from 149 (mostly employed) adults in the Northeast were used to assess relationships between invasiveness and several hypothesized antecedents. Correlation analyses showed that invasiveness was predicted by several factors (e.g., the extent to which the procedures erroneously discredited job applicants). Implications for personnel selection practices in work organizations are considered .
