Standardization and the Impact of Big 5 Factor Personality Test Subscales on Achievement (Published)
The latest research supports a five-factor structure to describe the personality of children, as well as of adults, confirming the structure proposed by many authors. The study aims to assess the underlying structure and psychometric properties of the Big Five Factor Personality Test among mixed professions employees as well as among students of different study programs. The study also aimed to measure the impact of neuroticism, extraversion, conscientiousness, openness, and agreeableness subscales on achievement. Data was gathered from 912 respondents from the mixed professions population and 501 respondents from the student population. A substantial proportion of respondents from the two populations of the study were classified as probable cases on the Big Factor Personality scale and subscales, with the samples recording higher mean Big Factor Personality subscales scores than many other respondent groups reported in the previous work. Confirmatory factor analysis supported the structure of five subscales of the Big Factor Personality Scale representing the personality of different professions and students from varying study programs. There was a linear relationship between neuroticism, extraversion, conscientiousness, openness, agreeableness, and achievement. Extraversion, cconscientiousness’, and openness were positive predictors of achievement while, neuroticism and agreeableness were negative predictors.
