Table 4. Best-fitting model for personal distress with type of pain and negative affect.

Personal Distress ~ Type of Pain + Negative Affect + (1 + Type of Pain|Subject) + (1|Item)
Fixed effects	Estimate (Std. Error)
Intercept	0.07 (0.45)
Psychological pain	1.02 *** (0.14)
Physical pain	2.39 *** (0.23)
Negative affect	0.12 ** (0.04)
Random effects	Explained variance (Std. Dev.)
Items	0.01 (0.11)
Subjects	0.38 (0.61)
Psychological pain	1.03 (1.02)
Physical pain	3.10 (1.76)

Linear mixed-effects model with type of pain and negative affect before the experiment as fixed effects and random intercepts for subjects and items as well as by-subject random slope for type of pain;

** p < .01,

*** p < .001.
