Pedrero, E. ; López-Durán, A. ; Fernández del Río, Elena (Universidad de Zaragoza)
Resumen: El Inventario Clinico Multiaxial de Millon (MCMI-II) es un cuestionario ampliamente utilizado en la clínica, especialmente en drogodependencias, para la evaluación de la personalidad. El objetivo del presente estudio es conocer la estructura factorial subyacente del MCMI-II en una muestra de 1.106 adictos a sustancias psicoactivas que inician tratamiento. Los participantes cumplimentaron el MCMI-II y el TCI-R. Se realizó análisis factorial exploratorio multivariado. Los resultados muestran que en el MCMI-II hay un factor principal que evalúa sintomatología de aparición reciente relacionada con el Eje I, una escala de ideación autolítica, dos escalas que exploran problemas relacionados con alcohol y otras drogas, dos de rasgos de personalidad normal y siete de rasgos de personalidad disfuncional. Aunque el objetivo del MCMI-II es evaluar la personalidad, los resultados indican que la mayor parte del mismo evalúa condiciones no necesariamente estables que han aparecido recientemente. Las escalas que miden rasgos disfuncionales de personalidad se combinan entre sí para configurar los trastornos, sin ajuste claro a la teoría de referencia. Se concluye que el uso del MCMI-II con fines diagnósticos debe considerar la presencia de condiciones inestables que pueden incrementar artefactualmente las cifras de prevalencia y de coexistencia de trastornos de personalidad y comportamientos adictivos.
Factorial dimensions of the Millon’s MCMI-II in substance addicts. The Millon Clinical Multiaxial Inventory II is a widely used questionnaire for the assessment of personality in clinical settings, especially in addictive behaviors. The aim of this study is to determine the underlying factorial structure of the MCMI-II in a sample of 1,106 drug-dependents who seek treatment. All participants completed the MCMI-II and the TCI-R. Multivariate exploratory factor analysis was performed. The results show that, in the MCMI-II, there is a main part that assesses symptoms of recent onset associated with the Axis I disorders, a scale that explores autolytic ideation, two scales that explore issues related to the use of alcohol and other drugs, two scales that assess normal personality traits, and seven scales that explore dysfunctional personality traits. Although the objective of the MCMI-II is the assessment of personality, the results indicate that the largest part of the questionnaire assesses not necessarily stable conditions and which have appeared recently. The scales measuring dysfunctional personality traits are combined to account for disorders without a clear match to the theory of reference. We conclude that, when using the MCMI-II with diagnostic purposes, one should consider the presence of unstable conditions that could artifactually increase the prevalence rates and the coexistence of personality disorders and addictive behaviors.
