Assessment of personality disorders through a new self-report instrument: the CEPER

Personality disorders are highly complex problems that are attracting increased attention. The information available about them is relatively scarce and their diagnosis many times difficult to carry out. Nowadays we have different instruments for their assessment, such as interviews and self-report questionnaires. A new questionnaire is put forward here for the assessment of styles of personality based on the disorders of personality proposed by the DSM-IV in the official classification and in its appendix. Some psychometric properties of the Exploratory Questionnaire of Personality (CEPER) are presented, including the Cronbach’ alpha, the reliability of the two halves and the convergent validity taking as criterion the Millon Clinical Multiaxial Inventory (MCMI-II). Data on differences between men and women in the different styles of personality of the present questionnaire are also included.
