Pearson correlations between pairs of criteria measures of compulsive checking

	Length of check	Recurrence time of checking	No. of stops before returning to check
Frequency of checking	−0.752**	−0.488**	−0.091
Length of check		0.284**	−0.105
Recurrence time of checking			0.410**

Cells with dark gray color refer to measures within the domain of vigor and cells with light gray color refer to measures within the domain of focus; non-shaded cells show correlations between these domains. The Pearson correlation coefficient was computed for the four groups combined (N = 94).

^**P≤0.01 (two-tailed).
