NEO Five-Factor Personality Questionnaire

Scale Analysis

The NEO Five-Factor Personality Questionnaire (NEW Five-Factor Inventory [NEW-FFI-60], Form S) is the abbreviated version of the NEO Revised Personality Inventory (NEO-PI-R), which was developed by Costa and McCrae in 2010.

Objective

The NEO Five-Factor Personality Questionnaire [NEW-FFI-60] is a tool designed to measure personality traits. It is based on the five-factor model of personality and is intended to capture those five core traits: neuroticism, conscientiousness, extraversion, agreeableness, and openness to experience.

Item Calibration

The NEO-FFI includes 60 statements, categorized into five personality factors, with each factor consisting of 12 statements. Evaluation is done using a 5-point Likert scale ranging from 0 (strongly disagree) to 4 (strongly agree).

Statistical Analysis

The questionnaire is intended for adult populations and can be administered individually or in groups. The personality profile is constructed based on scores received in each of the five traits and interpreted according to norms that vary by gender and student populations. The NEO-FFI items are designed to target the five personality traits. Each factor includes six indicative statements. Scores are summed to evaluate each of the five factors.

Validity and Reliability

The questionnaire shows adequate construct validity and good discriminant validity for its subscales. Internal consistency is satisfactory, with Cronbach’s alpha coefficients ranging from 0.64 to 0.85 (Costa & McCrae, 1992). It has been translated into Greek by Dimitriadou and Stalikas using the back-translation method.
