Note: Estimates for all model constrained variables, β (SE), estimate of regression association and accompanying standard error from multivariate model; ci.lb, lower bound of 95%Cl; ci.ub, upper bound of 95% Cl. Bold estimates represent significant associations at Bonferroni-corrected threshold. Assessment of overall model fit suggested an acceptable to good fit based on RMSEA (0.047) but not CFI (–0.075) and TLI (–0.013).
