Diagnosis of disruptive behavior disorders using the Millon Adolescent Personality Inventory.
Millon Adolescent Personality Inventory differential diagnosis of disruptive behavior disorder vs no behavior disorder was investigated. Results were twice cross-validated. Millon adolescent Scales 4, 5, 6, G, SS, and TT were closely related to diagnosis of behavior disorder. Two psychometric rules averaged 70% hits and 35% false positives over three samples, Rule 1 of > 2 elevations (baserate score > 63) among Scales 6-G-SS-TT and Rule 2 of Scale 4 elevated with Scale 5 or with one of 6-G-SS-TT. An ancillary rule was highly specific to behavior disorder (90%). Two broad dimensions or factors appeared to be represented in the key scales; Scales 4 and 5 exemplified a histrionic-narcissistic factor, while the 6-G-SS-TT combination typified behavioral conflict and instability.
