Descriptive information on intended drinks, drinks consumed, and their discrepancy

			Discrepancy (no. consumed – no. intended)
Category	M (SD)	M (SD)	M (SD)	Mdn	Range
All available days (N = 4,247 days)	3.69 (3.45)	4.80 (3.65)	1.11 (3.79)	1	-21 to 25
Days underestimated (by at least one drink) (58.79%; n = 2,497 days)	2.39 (3.14)	5.77 (3.58)	3.38 (2.73)	2	1 to 25
Days matched (no difference) (13.99%; n = 594 days)	5.57 (2.99)	5.57 (2.99)	N.A.	N.A.	N.A.
Days overestimated (by at least one drink) (27.22%, n = 1,156 days)	5.52 (3.03)	2.30 (2.85)	-3.22 (2.47)	-2	-21 to -1

Notes: Only drinking days with sufficient data to calculate a discrepancy score were included. Underestimation and overestimation were defined as a discrepancy of at least one drink. No. = number; n.a. = not applicable.
