Note. We conducted three alternative models to compare with the Family Stress Model (FSM) based on the discussion with the reviewers. The alternative model 1 is the reversed version of the FSM. The alternative model 2 changes all relations in the FSM as reciprocal. The alternative model 3 changes only the child problem behavior relationships in the FSM as reciprocal. See Figures A1, A2 and A3 in the Appendix for results of alternative models. We then conducted a series of Satorra-Bentler scaled chi-square different tests (Satorra & Bentler, 2010) across models. Results from the model fit comparisons indicated that the alternative models are statistically similar to the FSM (p-values >.256). We chose the original FSM because it had the strongest theoretical support based on the prior literature. χ²= chi-square value. Df = degrees of freedom. SCF = scaling correction factor. TRd = Satorra-Bentler chi-square difference. CD = difference test scaling correction. RMSEA = root mean square error of approximation. CFI = comparative fit index. TLI = Tucker-Lewis index. SRMR = standardized root mean square residual.
