This R Markdown document accompanies the manuscript "The Effects of Prison Experience and Social Support on Mental Health Among Inmates in Brazil" by Luis Anunciação, PhD, and colleagues. It provides a fully reproducible analysis pipeline for data preparation, descriptive statistics, psychometric processing, and hierarchical multiple regression modeling. In particular, it includes a replication of SPSS-style stepwise and blockwise regression procedures using R, with clear annotation and transparent code. While certain analytic steps were included to match legacy outputs (e.g., stepwise regression), the overall structure prioritizes clarity, reproducibility, and theoretical coherence.
