This study tested a 'wise' intervention (quick prompt of a specific psychological mec) in acute care hospital units to improve nurses' hand hygiene compliance (HHC). A multiple baseline design in two medical-surgical teaching hospitals in the United States. Hand hygiene data was collected using an electronic compliance monitoring system with…

This analysis employs a Bayesian framework to estimate the impact of a Cognitive-Behavioral Therapy (CBT) intervention on the recidivism of high-risk people under community supervision. The study relies on the reanalysis of experimental datal using a Bayesian logistic regression model. In doing so, new estimates of programmatic impact were…

As evidence-based interventions are scaled, fidelity of implementation, and thus effectiveness, often wanes. Validated fidelity measures can improve researchers' ability to attribute outcomes to the intervention and help practitioners feel more confident in implementing the intervention as intended. We aim to provide a model for the validation of…

Objective: In this article, we estimate the effect of a multidisciplinary collaboration program on the length of sickness absence. The intention with the program was to avoid long-term sickness absence by providing an early and holistic evaluation of the sick-listed individuals' conditions. The target group was individuals who were at risk of…

The study dealt with a research environment in which the treatment effect is heterogeneous, and in which individuals use their assessments of the treatment effect to decide whether or not to enroll in an intervention program. In this article, a new methodology is proposed for examining the validity of the specified research environment in a given…

Evaluation designs for social programs are developed assuming minimal or no disruption from external shocks, such as natural disasters. This is because extremely rare shocks may not make it worthwhile to account for them in the design. Among extreme shocks is the 2010 Chile earthquake. Un Buen Comienzo (UBC), an ongoing early childhood program in…

The chronic and relapsing nature of substance abuse points to the need for continuing care after a primary phase of treatment. This article reviews the economic studies of continuing care, discusses research gaps, highlights some of the challenges of conducting rigorous economic evaluations of continuing care, and offers research guidelines and…

A problem for program evaluators involves a search for ways to maximize internal validity and inferential power of research designs while being able to assess long-term effects of social programs. A multimethodological research strategy combining a delayed control group true experiment with a multiple time series and switching replications design…

An evaluation strategy in which a set of process indicators is applied to programs to reduce maternal mortality in developing countries is presented. The four-stage strategy is illustrated for three interventions: (1) providing safe abortion services; (2) increasing knowledge of obstetric complications; and (3) improving medical care quality. (SLD)

Synthesizes the long-term findings of three major evaluations of programs that began in the late 1980s and were designed to improve the self-efficacy of teenage mothers on welfare. Economic outcomes for the mothers improved over time, and the interventions had some positive effects, although they did not affect fertility. (SLD)

This article argues that evaluators must go further in mapping how clients' indigenous social structures complement or conflict with the centralized rational structure of program reforms. Evaluation of youth programs in Israel and the United States exemplifies how the respective social rules of program sponsor versus clients may be mutually…

This article presents a method for disentangling the effects of an intervention from changes that are due to growth and regression to the mean. The method is illustrated in the context of evaluating the effect of the Special Supplemental Food Program for Women, Infants, and Children (WIC) on infant growth. (Author/LC)

Describes a method that uses program participants' compliance with program instructions as a means of classifying participants and in that way obtains a randomized control group for a subset of participants. Illustrates two variations of the method through a large smoking-intervention project. (SLD)

In this article, the authors discuss program evaluation of intervention studies when the outcome of interest is collected routinely at equally spaced intervals of time. They illustrate concepts using data from the American Stop Smoking Intervention Study, where the outcome is state per capita tobacco consumption. States differ widely in mean…

Based on a complex time series evaluation, a 2-year intervention in 40 supermarkets in Washington (DC) and Baltimore (Maryland) indicates that a nutrition education program could produce small but positive changes in consumers' food purchasing behavior. Limitations of the study and its implications for future evaluations are discussed. (SLD)
