Bold indicates the non-invariant model (error co-variance and error residuals significantly different between groups).

^{^a}

Tests of error co-variances and error residuals for each individual negatively worded item of the ACSS–FAD showed non-significant degradation in model fit, suggesting strict invariance (same between groups).
