Purpose

The purpose of the questionnaire is to assess both normal and pathological characteristics (traits) of personality. It is a diagnostic tool that allows mental health professionals to identify key personality features in individuals, both in the context of typical personality development and psychopathology.

General Description

The questionnaire consists of 28 scales, divided into two main parts. The first part includes 16 scales related to normal personality traits, based on the well-known 16 Personality Factors Questionnaire (16 PF). These scales assess traits such as boldness, intelligence, emotional stability, dominance, liveliness, social sensitivity, conscientiousness, adventurousness, sensitivity, alertness, idealism, guilt-proneness, self-control, tension, trust, and conservatism.

The second part includes 12 additional scales that assess pathological personality characteristics. These pathological scales address areas such as psychotic tendencies, paranoia, depression, anxiety, worry, antisocial behavior, schizoid detachment, psychosomatic complaints, hostility, emotional instability, self-destructive tendencies, and passive dependency.

In total, the CAQ includes 272 items to be answered by the individual. The questionnaire can be administered individually or in groups. Completion time typically ranges between 90 and 120 minutes, depending on the examinee’s concentration and cooperation. It is intended for individuals aged 16 and older, and there is no time limit for completion.

Scoring Method

Scoring is performed using specific answer keys for each of the two main groups of scales (normal and pathological). First, raw scores are calculated for each scale. These are then converted into sten scores (standardized scores with a mean of 5.5 and a standard deviation of 2, on a scale from 1 to 10).

Results are typically presented through a personality profile chart, where the distribution of scores per scale is visually depicted, allowing comparison with normative data. Norms are available for both the general population and special groups (e.g., university students, psychiatric patients, inmates, etc.).

Validity and Reliability

The reliability and validity of the questionnaire have been confirmed through numerous international research studies. In Greece, the CAQ has been translated, adapted, and standardized on representative samples. Preliminary results of the Greek edition indicate very satisfactory levels of internal consistency and construct validity. The tool is considered suitable for both research and clinical use.
