The principle objective of this study was to explore the degree of overlap between similar personality sub scales on the EZ-Yale Personality Questionnaire (EZPQ) (Zigler et al, 2002), and the NEO Personality Inventory revised (NEO PI-R) (Costa and McCrae, 1992), in a sample of adults with mild intellectual disability. A within subjects design was used. Twenty seven participants completed the EZPQ and the NEO PI-R personality questionnaires, each in relation to a specific client with mild intellectual disability. Pearson correlations and Spearman rho correlations were used to investigate the associations between sub-scales of the two questionnaires that purport to measure similar aspects of personality. Significant positive correlations were found between the Agreeableness (NEO PI-R) and Obedience (EZPQ) sub-scales and between the Conscientiousness (NEO PI-R) and Effectance Motivation (EZPQ) sub-scales. The associations between the other personality sub-scales were less than anticipated. The findings were discussed in terms of the possible future utility of the EZPQ and NEO PI-R in the assessment of psychiatric disorders, particularly personality disorder. The lack of correlation was discussed in relation to differences in the way the NEO PI-R and EZPQ were developed and standardised.
