Suppоse а teаm оf reseаrchers is interested in investigating the assоciation between childhood adversity and substance abuse. Before conducting their study, they drew a directed acyclic graph (DAG) to determine what confounder variables they need to adjust for in the analyses. Figure 2 shows the DAG that the researchers drew. For each of the variables in Figure 2 (job opportunities, anxiety, and childhood socioeconomic status) describe: What type of “third variable” each variable is (max. 3 points). Whether the researchers should or should not adjust for the respective variable in the analysis stage to minimize confounding (max. 3 points). Why the researchers should or should not adjust for the respective variable (max. 3 points).
