Note. PPI = prepulse inhibition.

a

Covariances differed by experimental group: control: 0.82** (0.31), matched affect dysregulation (matched-AD): −0.09 (0.02), nonsuicidal self-injury (NSSI): −0.02 (0.04), no pain: −0.14** (0.05).

b

Covariances differed by experimental group: control: 0.76** (0.30), matched-AD: 0.01 (0.02), NSSI: 0.07 (0.04), no pain: 0.03 (0.02).

c

Covariances differed by experimental group: control: −0.76** (0.38), matched-AD: 0.01 (0.02), NSSI: 0.07 (0.04), no pain: 0.03 (0.02).

d

Means (SE) for control group: −91.82 (1.68)**, matched-AD, NSSI, and no pain groups: −83.44 (1.78)**.

e

Means (SE) for control and matched-AD groups: 3.95 (1.97)**, NSSI group: −8.56 (4.39)**, no pain group: −2.92 (2.30).
