Description

The Personality Traits Test 5 (PTT5-75 / TPQue5) is a shortened personality assessment instrument developed by I. Tsaousis and based on the Five-Factor Model of personality (Big Five).

The instrument includes 75 items assessing five major personality dimensions: Extraversion, Neuroticism, Openness to Experience, Agreeableness, and Conscientiousness. In addition, it contains 26 items assessing two validity-related scales, namely a lie scale and a social desirability scale. Overall, the instrument consists of 101 statements.

Purpose

The main purpose of the PTT5-75 is to provide a concise but comprehensive profile of an individual’s personality characteristics.

By assessing the five major personality domains, the instrument can support the study of individual differences and the relationships between personality and psychological, social, or occupational variables.

Core Dimensions

Extraversion refers to characteristics such as sociability, activity, energy, and a tendency toward interpersonal engagement.

Neuroticism is associated with emotional instability and a greater tendency to experience negative emotional states.

Openness to Experience reflects curiosity, receptiveness to new ideas, experiences, and alternative ways of thinking.

Agreeableness refers to interpersonal characteristics such as cooperation, trust, and a generally positive orientation toward others.

Conscientiousness is associated with organization, responsibility, self-discipline, persistence, and goal-directed behavior.

Normative Sample

The evaluation of the test was based on a sample of 488 individuals aged 18 to 45 years. Normative scores are available both as percentile values and T-scores, with separate norms reported for the general population and for employed individuals.

These normative data allow individual scores to be interpreted comparatively and can support the development of a more detailed personality profile.

Scoring

Each of the five major personality scales consists of 15 items. The total score for each dimension is obtained by summing the scores assigned to the corresponding items.

The instrument also includes an electronic scoring system for all scales and a digital format for presenting an individual personality profile.

Validity

The structure of the PTT5-75 was examined using both exploratory and confirmatory factor analysis, supporting its theoretical basis in the Five-Factor Model. Additional studies have also reported satisfactory concurrent validity through associations with other personality measures based on the same theoretical framework and with the full version of the instrument.

Construct validity is further supported by associations with other personality measures, including the EPQ, 16PF, and MMPI, as well as with psychological variables such as emotional intelligence, psychological well-being, occupational stress, career decision-making, social skills, and organizational culture.

Reliability

Internal consistency is reported as satisfactory, with Cronbach’s alpha coefficients ranging from 0.73 to 0.84. Specifically, the reported coefficients are 0.81 for Extraversion, 0.84 for Neuroticism, 0.74 for Openness to Experience, 0.79 for Agreeableness, and 0.73 for Conscientiousness.

Test-retest reliability coefficients range from 0.74 to 0.87, indicating satisfactory stability of the personality dimensions across repeated assessments.

Research and Applied Uses

The PTT5-75 may be used in research examining personality structure, occupational behavior, psychological well-being, workplace adjustment, and career decision-making.

It may also be applied in counseling and career guidance settings, provided that administration and interpretation follow the procedures and standards established for the instrument.
