Modeling the Triadic System and Interference

Formalize the vee relationship as a network graph with nodes (individuals), dyads (pairs), and a triad (system).

Define an exposure mapping that formally captures how each member's outcome depends on the full treatment vector (interference).

Redefine causal estimands (e.g., direct, spillover, total effects) for an individual under interference from their partners.

Formulate research questions about satisfaction maximization in terms of these network-aware causal estimands.

Specify treatment variables (e.g., living arrangements) and measurable satisfaction outcomes for each node and dyad.

Map potential mediating pathways (e.g., autonomy, security) and shared confounders (e.g., household stress) onto the system.
