Description

The Gala Professional Personality Test (GPT-350) is a comprehensive psychometric instrument developed by M. Galanakis and A. Stalikas to assess personality characteristics associated with occupational adjustment, professional performance, and career success. Specifically designed for use within the Greek workforce, the instrument is grounded in the Five-Factor Model of Personality (Big Five) and aims to provide a multidimensional evaluation of behavioral tendencies that are particularly relevant to workplace environments.

The GPT-350 consists of 200 statements covering a broad range of behavioral, cognitive, emotional, and interpersonal characteristics. These statements are organized into ten personality dimensions, providing a detailed profile of individual strengths and developmental areas. The instrument is intended for applications in organizational psychology, human resource management, personnel selection, leadership development, career counseling, and employee assessment.

By offering a comprehensive evaluation of work-related personality characteristics, the GPT-350 assists organizations in identifying behavioral patterns associated with adaptability, productivity, teamwork, leadership potential, and long-term professional development.

Purpose

The primary purpose of the Gala Professional Personality Test (GPT-350) is to evaluate ten personality dimensions that are associated with successful adaptation and effectiveness in occupational settings. The instrument helps identify behavioral characteristics that influence workplace performance, interpersonal relationships, decision-making, motivation, and professional growth.

Furthermore, the GPT-350 is widely applicable in:

  • Personnel recruitment and selection.
  • Talent identification and management.
  • Leadership assessment and development.
  • Career counseling and vocational guidance.
  • Employee coaching and professional development.
  • Organizational research and human resource evaluation.

Data Analysis and Interpretation

The GPT-350 provides quantitative scores across ten personality dimensions that describe important aspects of occupational behavior, including:

  • Extraversion
  • Spontaneity
  • Responsibility
  • Ambition
  • Assertiveness
  • Energy
  • Philosophical–critical thinking
  • Independence
  • Self-respect
  • Courage

Participants evaluate statements describing behaviors, attitudes, habits, and beliefs related to each personality dimension. Individual responses are aggregated to generate separate scores for each domain, allowing researchers and practitioners to develop a comprehensive occupational personality profile.

The resulting scores may be examined in relation to important psychological and organizational variables such as:

  • Job performance
  • Leadership effectiveness
  • Organizational commitment
  • Teamwork
  • Adaptability
  • Career advancement
  • Employee engagement
  • Job satisfaction
  • Decision-making style
  • Professional resilience

The GPT-350 is particularly valuable for organizational assessment, executive coaching, leadership development, occupational psychology, and scientific research focusing on workplace behavior.

Scoring

The GPT-350 assesses personality through ten independent numerical indices, each representing one of the personality dimensions measured by the instrument.

Scores for each dimension typically range from negative values to +40, with higher scores indicating stronger expression of the corresponding personality characteristic. Each index is calculated by combining participants’ responses to statements concerning behaviors, thoughts, attitudes, and habits related to that personality domain.

According to the available development data, the instrument underwent an initial pilot evaluation involving 350 participants from across Greece and demonstrated satisfactory preliminary internal consistency (Cronbach’s α = 0.77). At the time of reporting, standardization and psychometric validation were still in progress, and comprehensive validity and reliability studies had not yet been published. Therefore, interpretation of the results should be made with consideration of the instrument’s developmental status.
