We investigated the causal impact of conflict-related violence on individual mental health and its potential pathways in Colombia. Using data from before and after the 2016 peace accord between the Colombian government and the Revolutionary Armed Forces of Colombia (FARC), we adopted a difference-in-differences empirical design combined with instrumental variables estimation. We also used formal mediation analysis to investigate a possible mediating role of alcohol consumption in the relationship between conflict exposure and mental health. Our results did not support the hypothesis that changes in exposure to conflict violence after the peace accord causally led to any changes in individual mental health. We were unable to identify a statistically significant mediating effect of alcohol consumption in the relationship between exposure to conflict violence and mental health.
我们在哥伦比亚调查了与冲突相关的暴力对个人心理健康的因果影响及其潜在途径。利用哥伦比亚政府与哥伦比亚革命武装力量（FARC）2016年和平协议前后的数据，我们采用了双重差分实证设计并结合工具变量估计。我们还使用了正式的中介分析来研究饮酒在冲突暴露与心理健康关系中可能的中介作用。我们的结果不支持这样的假设，即和平协议后冲突暴力暴露的变化会因果性地导致个人心理健康的任何变化。我们无法确定饮酒在冲突暴力暴露与心理健康关系中的统计学显著中介效应。
