Notes: number of obs. = 18,958; model controls for random effects of families; Bayesian estimations produce credible intervals (CI), which are the intervals within which the parameter values fall at some particular probability.
Model 2 tests if higher earthquake intensity affects the relationship between family embeddedness structure and how long it took egos to contact a nonfamily plan member (i.e., “friend”). A negative interaction term with (1) showed that at higher earthquake intensity, completely unembedded family structures were significantly faster in calling friends; a positive interaction term with (2) shows that at higher earthquake intensity levels, fully embedded family structures were significantly slower in calling friends. In other words, at higher earthquake intensity, people in completely unembedded families exhibited greater relative urgency in reaching out to friends, while people in fully embedded families were relatively less urgent.
