Table 4.

Study 1: perceived normality of the amount of alcohol participants personally consumed during the study and the serving size provided in the standard and reduced serving size conditions; means are estimated from multi‐level regression model accounting for data clustering within participant pairs.

	Serving size condition
	Reduced (n = 60)		Standard (n = 54)
	Mean (SE)	(95% CI)	Mean (SE)	(95% CI)	d
Normality of amount consumed during study	3.80 (0.15)	(3.50, 4.10)	3.68 (0.14)	(3.40, 3.97)	0.11
Normality of serving size	3.70 (0.15)	(3.40, 4.01)	3.35 (0.14)	(3.06, 3.64)	0.32

Perceived normality was measured on a 5‐point Likert scale, with greater scores indicating greater perceived normality.
