q3 i? The mutualism model could be equality constrained across sexes without notable fit loss, and allowing age to directly predict change scores did not improve fit. → Kievit 2017

q3 · i? · associational · r3

Control analysis in the Results section of the two-wave cohort study; a separate sensitivity check found allowing age to predict change scores did not improve fit (Δχ2(2) = 0.13, p = .93), supporting age as a Time 1 covariate only.

"Further control analyses suggested that the mutualism model could be equality constrained across sexes without a notable drop in model fit, Δχ 2(18) = 17.184, p = .51."
