Factor-Based Prototypes of the Million Adolescent Clinical Inventory in Adolescents Referred in Residential Treatment

Abstract

Although well received by the clinical community, there have been few published reports on the use of the Millon Adolescent Clinical Inventory (MACI). There have been no published studies describing use of the MACI with a residential treatment population. In addition, there have been no published reports investigating the factor structure of the MACI. A principal components factor analysis was performed for all MACI scales and sex for 251 adolescents referred to a residential treatment facility. Five factors were found accounting for 77.4% of the variance. Factor-based prototypes were generated from these results: Factor 1 defines a prototype for Defiant Externalizers, Factor 2 for Intrapunitive Ambivalent Types, Factor 3 for Inadequate Avoidants, Factor 4 for Self-Deprecating Depressives, and Factor 5 for Reactive Abused Types. Prototype descriptions and clinical vignettes are included for each of the 5 factor-based prototypes. These results are consistent with our clinical experience with this population. Prototype analysis may offer a powerful way of enhancing the utility of the MACI in clinical settings.

Internalizing and Externalizing Personality Dimensions and Clinical Problems in Adolescents

“…The MACI has 27 clinical scales that tap clinical syndromes, expressed concerns, and personality styles and contains validity checks, which all participants included in the current study passed. This widely used assessment instrument [17,18], has demonstrated acceptable internal consistency, testretest reliability, and has been validated against various measures by several different research groups [17,19,20]. In the present study, the 12 MACI personality pattern scales that correspond somewhat to the DSM-IV personality disorders: Introversive (similar to schizoid), Inhibited (avoidant), Doleful (depressive), Submissive (dependent), Dramatizing (histrionic), Egotistic (narcissistic), Unruly (antisocial), Forceful (sadistic), Conforming (obsessive-compulsive), Oppositional (passive-aggressive), Self-Demeaning (self-defeating), and Borderline.…”

Personalidad y gravedad delictiva en adolescentes con conducta antisocial persistente

“…El Inventario MACI (Millon,1993) aporta una buena medición del funcionamiento psicológico y conductual de los adolescentes (Romm, Bockian, & Harvey, 1999) junto con la diferenciación de trastornos específicos (Faúndez & Vinet, 2009;Ferrer & Kirchner, 2014), permitiendo discriminar características de adolescentes infractores de ley, donde las escalas transgresor y poderoso, junto a insensibilidad social, predisposición delictual, tendencia al abuso de substancias, impulsividad y ansiedad muestran el mayor tamaño de efecto al diferenciar a este grupo de adolescentes de una muestra equivalente, pero convencional.…”

Self‐report objective measures of personality for children: A review of psychometric properties for RQC

“…Romm, Bockian, and Harvey (1999) conducted a factor analysis among a hospitalized sample and suggested five factors: defiant externalizing, intrapunitive ambivalence, inadequate avoidance, self-deprecating depression, and reactive abused.…”
