Standards of Evidence for Conducting and Reporting Economic Evaluations in Prevention Science.

Over a decade ago, the Society for Prevention Research endorsed the first standards of evidence for research in preventive interventions. The growing recognition of the need to use limited resources to make sound investments in prevention led the Board of Directors to charge a new task force to set standards for research in analysis of the economic impact of preventive interventions. This article reports the findings of this group's deliberations, proposes standards for economic analyses, and identifies opportunities for future prevention science. Through examples, policymakers' need and use of economic analysis are described. Standards are proposed for framing economic analysis, estimating costs of prevention programs, estimating benefits of prevention programs, implementing summary metrics, handling uncertainty in estimates, and reporting findings. Topics for research in economic analysis are identified. The SPR Board of Directors endorses the "Standards of Evidence for Conducting and Reporting Economic Evaluations in Prevention Science."

How has the economic downturn affected communities and implementation of science-based prevention in the randomized trial of communities that care?

This study examined implications of the economic downturn that began in December 2007 for the Community Youth Development Study (CYDS), a longitudinal randomized controlled trial of the Communities That Care (CTC) prevention system. The downturn had the potential to affect the internal validity of the CYDS research design and implementation of science-based prevention in study communities. We used archival economic indicators and community key leader reports of economic conditions to assess the extent of the economic downturn in CYDS communities and potential internal validity threats. We also examined whether stronger economic downturn effects were associated with a decline in science-based prevention implementation. Economic indicators suggested the downturn affected CYDS communities to different degrees. We found no evidence of systematic differences in downturn effects in CTC compared to control communities that would threaten internal validity of the randomized trial. The Community Economic Problems scale was a reliable measure of community economic conditions, and it showed criterion validity in relation to several objective economic indicators. CTC coalitions continued to implement science-based prevention to a significantly greater degree than control coalitions 2 years after the downturn began. However, CTC implementation levels declined to some extent as unemployment, the percentage of students qualifying for free lunch, and community economic problems worsened. Control coalition implementation levels were not related to economic conditions before or after the downturn, but mean implementation levels of science-based prevention were also relatively low in both periods.

A Geography-Specific Approach to Estimating the Distributional Impact of Highway Tolls: An Application to the Puget Sound Region of Washington State.

This study contributes to the debate about tolls' equity impacts by examining the potential economic costs of tolling for low-income and non-low-income households. Using data from the Puget Sound metropolitan region in Washington State and GIS methods to map driving routes from home to work, we examine car ownership and transportation patterns among low-income and non-low-income households. We follow standard practice of estimating tolls' potential impact only on households with workers who would drive on tolled and non-tolled facilities. We then redo the analysis including broader groups of households. We find that the degree of regressivity is quite sensitive to the set of households included in the analysis. The results suggest that distributional analyses of tolls should estimate impacts on all households in the relevant region in addition to impacts on just users of roads that are currently tolled or likely to be tolled.

Childlessness and the economic well-being of older Americans.

OBJECTIVES: The study's purpose is to examine the relationship between childlessness and two key indicators of older Americans' economic well-being: income and wealth. METHODS: Using the Health and Retirement Survey, the study estimates this relationship and compares findings from standard ordinary least squares, random effects, quantile regression, and two propensity score models. RESULTS: Compared with married parents, childless married couples tend to have slightly more income and about 5% more wealth. Unmarried childless men enjoy no income advantage over unmarried fathers but have 24%-33% more wealth. Compared with older unmarried mothers, unmarried childless women have 12%-31% more income and about 33% more wealth. The strength of these relationships increases as one moves up the distribution of income or wealth. DISCUSSION: This study provides evidence on the relationship between childlessness and both income and wealth, including the first evidence for men. The findings may be useful for persons concerned about the determinants of childless adults' well-being as well as the long-run financial demands on public programs that provide income support, health and nursing home care, and social services for older Americans.

Effects of enhanced foster care on the long-term physical and mental health of foster care alumni.

CONTEXT: Child maltreatment is a significant risk factor for adult mental disorders and physical illnesses. Although the child welfare system routinely places severely abused and/or neglected children in foster care, no controlled studies exist to determine the effectiveness of this intervention in improving the long-term health of maltreated youth. OBJECTIVE: To present results of the first quasi-experimental study, to our knowledge, to evaluate the effects of expanded foster care treatment on the mental and physical health of adult foster care alumni. DESIGN: We used a quasi-experimental design to compare adult outcomes of alumni of a model private foster care program and 2 public programs. The latter alumni were eligible for but not selected by the private program because of limited openings. Propensity score weights based on intake records were adjusted for preplacement between-sample differences. Personal interviews administered 1 to 13 years after leaving foster care assessed the mental and physical health of alumni. SETTING/ PARTICIPANTS: A representative sample of 479 adult foster care alumni who were placed in foster care as adolescents (14-18 years of age) between January 1, 1989, and September 30, 1998, in private (n = 111) or public (n = 368) foster care programs in Oregon and Washington. More than 80% of alumni were traced, and 92.2% of those traced were interviewed. INTERVENTION: Caseworkers in the model program had higher levels of education and salaries, lower caseloads, and access to a wider range of ancillary services (eg, mental health counseling, tutoring, and summer camps) than caseworkers in the public programs. Youth in the model program were in foster care more than 2 years longer than those in the public programs. RESULTS: Private program alumni had significantly fewer mental disorders (major depression, anxiety disorders, and substance use disorders), ulcers, and cardiometabolic disorders, but more respiratory disorders, than did public program alumni. CONCLUSION: Public sector investment in higher-quality foster care services could substantially improve the long-term mental and physical health of foster care alumni.

Adolescent expectations and desires about marriage and parenthood.

Using data collected in 2000 on a racially and ethnically diverse sample of high school seniors, this study analyzes adolescents' expectations and desires about marriage and parenthood, including unwed parenthood. The conceptual framework combines family context, opportunity cost, and social-psychological perspectives. Each perspective receives empirical support. Race, ethnicity, gender, parental education, and parental expectations for their child's education show significant relationships with expectations and desires about marriage and parenthood. Adolescents with higher opportunity costs, as indicated by better grades and higher expectations for their schooling, expect and desire to marry and have children at older ages. The relationships between parental education and parental expectations for their child's education and the outcomes are largely mediated through opportunity costs. Significant relationships between locus of control and the outcomes provide empirical support for the social-psychological element of the framework.

Do children from welfare families obtain less education?

In this study, we analyzed whether parents' receipt of welfare affects children's educational attainment in early adulthood, independent of its effect through changing family income. We used data from the Panel Study of Income Dynamics with information on parents' welfare receipt over the first 15 years of childhood. Cross-sectional results show that greater exposure to welfare is significantly associated with children's poorer educational attainment. Family fixed-effect regressions also indicate a negative effect of exposure to welfare, but its overall pattern is less consistent. Although exposure to welfare in early childhood has no effect, in adolescence and, to a lesser degree, in middle childhood, its effect is often negative.
