Table 7 Model with SD as an independent predictor of the expressed opinion (Figure 4) tested independently with data from the high and low SD groups

From: Methodological considerations regarding response bias effect in substance use research: is correlation between the measured variables sufficient?

Fit index	*Good fit/Cut-off*	High SD group	Low SD group
Overall fit	p > 0.05	χ² = 18.498, df = 13, p = .140	χ² = 17.793, df = 13, p = .166
