Replication package for: Community mental health centre openings and suicide mortality in Chile (2002–2025)

Replication package for the study "Community mental health centre openings and suicide mortality in Chile (2002–2025): a staggered difference-in-differences study" (Montiel A, Olivares F; submitted to The Lancet Psychiatry). The study estimates the effect of the opening of the first community mental health centre (CMHC, known in Chile as COSAM) on municipal suicide mortality in Chile, using a municipality-year panel of 287 municipalities (2002–2025) and difference-in-differences estimators robust to treatment-effect heterogeneity under staggered adoption (Callaway–Sant'Anna and related estimators). This record contains: README.md: full documentation: software requirements (Stata 17; csdid 1.81, did_multiplegt_dyn, jwdid 2.2, ppmlhdfe 2.3.3, honestdid 1.3.0), replication instructions, and licensing. cmhc_panel.dta: aggregated municipality-year analytical panel (287 municipalities, 2002–2025, population aged 15 years or older), with all variables required to reproduce the analyses. CMHC_Data_Dictionary.pdf: data dictionary defining each field. opening_CMHC.dta: facility-level dataset of CMHC opening dates (ministerial and verified date for each facility) used to construct the treatment variable. CMHC_Study_Protocol.pdf: study protocol (prepared retrospectively). 01_build_panel.do: Stata code building the panel from the raw sources (requires the individual-level DEIS death records, not redistributable; provided for transparency). 02_analysis.do: Stata code reproducing all analyses, tables, and figures from cmhc_panel.dta; runs without restricted data. Individual-level death records cannot be shared by the authors but are publicly available from the Department of Health Statistics and Information (DEIS) of the Chilean Ministry of Health (https://deis.minsal.cl).
