For the Beck Depression Inventory, positive correlations indicate higher levels of depression are related to increased personality disturbance. * = p < 0.05, ** = p < 0.01, *** = p < 0.001 |
Bilateral Ventromedial Prefrontal Damage: (Barrash et al, 2000)
The IRSPC was shown to discriminate between patients with Prefrontal lesions with bilateral involvement of the ventromedial region, Prefrontal lesions without bilateral involvement of the ventromedial region and non-prefrontal lesions (refer to the "IRSPC Ratings of Severity and Change" Table in the "normative data" section of this summary for details"
