		Self-Reported Weighing: 12 Months^a (n = 182)				Self-Reported Weighing: 24 Months^b (n = 167)
Objective Weighing Frequency		Monthly or less	Weekly	Daily	Weighted Kappa	Monthly or less	Weekly	Daily	Weighted Kappa
	Monthly or less	3.3	3.3	0.6		18.6	25.8	7.2
	Weekly	2.2	45.6	13.2		6.0	23.4	12.6
	Daily	0.0	0.0	31.9		0.0	0.0	6.6
					0.67^***				0.27^***

Notes.

For comparison with 12-month self-report, objective weighing covers period from baseline to 12-month assessment.

For comparison with 24-month self-report, objective weighing covers period from 12 month assessment to 24 month assessment. Values are the percent of total sample for that time period.
