Genetic and environmental parameter estimates and fit indices for the sex-equated univariate model of victimization at primary school and secondary school

Primary School

Full model (ACE) 0.55 0.15 0.30
  AE model 0.71 0.29 2.11 1 .15
  CE model 0.58 0.42 24.24 1 <.001

Note: For the model on primary school data, thresholds and parameters could be equated across gender without significant loss of model fit (Δχ2 = 8.3; Δdf = 4, p = 0.1). For the secondary school model, parameter estimates could be equated across gender without significant loss of model fit (Δχ2 = 3.0; Δdf = 2, p = 0.2), but thresholds could not (Δχ2 = 6.8; Δdf = 2, p = 0.03), reflecting the mean gender differences observed in victimization at secondary school. A, additive genetic; C, shared environment; E, nonshared environment.
