Results of linear regression models predicting OCS severity at Time 2 from anxiety sensitivity at Time 1

	OCS severity at Time 2
	β	R 2
Univariate model
AS at Time 1	.33 (.28–.39)***	.10
Multivariate model I
OCS at Time 1	.41 (.36–.47)***	.22
AS at Time 1	.12 (.06–.17)***
Multivariate model II
OCS at Time 1	.37 (.31–.43)***
Anxiety at Time 1	.07 (−.01–.15)	.23
Depression at Time 1	.05 (−.01–.12)

95% confidence intervals in parentheses. Analyses were conducted using robust clustering for twin pairs; all analyses adjusted for age and sex.

β, standardized coefficient; AS, anxiety sensitivity; and OCS, obsessive–compulsive symptoms.
