RESUMO:

Causal inference in Statistics considers statistical approaches to establish a causal relationship between manipulable variables (treatment/intervention) and an outcome and it has been vastly developed methodologically in the last few decades. It is well-known that selection bias is likely to lead to incorrect inference in observational studies. Matching methods have been used as an alternative to the definition of comparison groups through the computation of propensity scores. Traditionally, the use of Propensity Score Matching (PSM) involves data analysis of observational studies under assumption of independence of the sample units.The underlying assumption, however, can be rather unreasonable when repeated measures of the outcome are collected in a longitudinal study. Recently, methods have being proposed to incorporate PSM into diverse dependency structures in the statistical model's framework (Li et al, 2013 e Arpino et al, 2016). When the treatment is initiated sequentially during a period of time, a class of longitudinal matching methods have also being proposed in the literature to emulate a random experiment (Li et al, 2001; Lu, 2005; Thomas et al, 2020). The goal of this dissertation is to systematically organize and summarize the statistical methodology involving propensity scores for the estimation of causal effects when analyzing data with longitudinal dependency structure. These methodologies are illustrated with the analysis of three datasets with different longitudinal dependency structure
