Main effects and interactions of predictor variables on SUDS and imagery vividness scores.

		Fixed Effects			Random Effects		Model AIC
	Effect	B	SE b	95% CI	Slope	Intercept
Vividness Ratings					.06**	2.98**	1451.63
	Session	.002	.06	−.12, .12
	Gender	−.08	.44	−.96, .80
	Gender x Session	−.21	.09	−.39, −.03*
Paired SUDS scores					19.31**	252.44**	3479.07
	Session	−8.26	.71	−9.68, −6.85**
	Vividness	2.35	.63	1.10, 3.59**
	Vividness x Session	−.84	.25	−1.33, −.34**

Note.

^**significant at the .01 level;

^*significant at the .05 level.

SUDS = Subjective Units of Distress Scale. SE = standard error. CI = confidence interval. AIC = Akaike’s Information Criterion. CIs that do not include zero indicate significant predictors. Vividness ratings are square root transformed and, therefore, produce Bs with signs in the opposite direction from what is indicated. To ease interpretation, signs of Bs and the 95% confidence intervals have been reversed to be more intuitive.
