TABLE 2.

Hierarchical regression analysis summary for variables predicting the OP Severity Scale scores among OP patients (N = 58)

Variable	B	SE B	β
Step 1
SCL	1.84	0.30	.62^*
Step 2
SCL	1.11	0.29	.38^*
OF Severity Scale	0.68	0.13	.51^*
Step 3
SCL	0.77	0.31	.26^*
OF Severity Scale	0.52	0.14	.39^*
OCC Severity Scale	0.76	0.32	.29^*

Note. R² = .40 for Step 1; ΔR² = .20 for Step 2; ΔR² = .04 for Step 3 (ps < .05). OP patients = patients with at least one episode of orthostatic panic in the last month; SCL = The average of the Symptom Checklist-90-R’s anxiety and depression subscales; OF = Orthostatic Flashback; OCC = Orthostatic Catastrophic Cognitions. All scales are rated on a 0–4 Likert-type scale.
