Abstract
The aim of the present study was to examine the psychometric properties of the Millon Clinical Multiaxial Inventory – III (MCMI-III) in an Australian community setting. The sample consisted of 818 (468 males, & 350 females) Australian community members who applied for positions within a Queensland emergency services organisation from 2002 till 2004. Previous studies that have used the MCMI have identified three to five factors underpinning the MCMI’s basic structure. For example, Retzlaff and Gibertini (1990) used factor analysis to assess the validity of the MCMI-I. Results identified a three-factor structure which the authors entitled the ‘Personality Factor scales’ and a five-factor structure which they named the ‘Clinical Convergence scales. In addition, it was concluded that the personality and clinical scales had high reliability across several populations and demonstrated high and appropriate validity estimates. Similarly, Aluja, Cuevas, Garcia, and Garcia (2007) used principal components analysis to explore the relationship between the basic dimensions of the Zuckerman personality model and the personality scales of a Spanish version of the MCMI-III. A clear five-factor structure related to most of the personality disorders was demonstrated. In the current study, factor analysis was conducted with direct oblimin rotation. Five factors were identified: Factor 1: Generalised Maladjustment, Factor 2: Narcissistic versus Emotional Instability, Factor 3: Trauma, Factor 4: Reactive Cognition versus Poor Impulse Regulation, Factor 5: Depressive Thinking. Results indicated that expectations regarding structural invariance were partially supported, although the amount of variance accounted for was low. The low variance was considered a reflection of sampling issues such as sample size and homogeneity. Overall, results indicated that restriction of range may explain the low total variance accounted for in the factor solution. Consequently, these results cannot generalise beyond a job applicant population.
