چکیده
Since the seminal paper by Rosenbaum and Rubin (1983b) on propensity score analysis, research using propensity score analysis has grown exponentially over three decades. Nevertheless, some methodological and practical issues still remain unresolved. This introductory chapter describes these issues along with an introduction to basic concepts of propensity score analysis. The remaining chapters in this book represent a collective effort to further address these issues and provide demonstrations and recommendations on how to use propensity score analysis appropriately and effectively for various situations. The rest of this chapter proceeds as follows: It starts with a general introduction to propensity score analysis based on the theoretical framework of causal inference, followed by a detailed description of four major steps in propensity score analysis, and concludes with a brief discussion of current issues in propensity score analysis.

Propensity Score Methods in Nursing Research: Take Advantage of Them but Proceed With Caution.
Intervention research on health outcomes is important to advancing the nursing science. Using randomized controlled trials (RCTs) to estimate intervention (or treatment) effects is optimal for this purpose. Unfortunately, for practical or ethical reasons, RCTs are often not feasible, and thus, researchers often rely on observational or non-RCT data to estimate treatment effects. Such practice p...
متن کاملPropensity score interval matching: using bootstrap confidence intervals for accommodating estimation errors of propensity scores
BACKGROUND Propensity score methods have become a popular tool for reducing selection bias in making causal inference from observational studies in medical research. Propensity score matching, a key component of propensity score methods, normally matches units based on the distance between point estimates of the propensity scores. The problem with this technique is that it is difficult to estab...

Propensity score methods allow investigators to estimate causal treatment effects using observational or nonrandomized data. In this article we provide a practical illustration of the appropriate steps in conducting propensity score analyses. For illustrative purposes, we use a sample of current smokers who were discharged alive after being hospitalized with a diagnosis of acute myocardial infa...
