dc.description.abstractAims: There is dearth of information on the psychometric of measures of personality on Nigerian population. This study investigates the internal consistencies and validity scores on the Mini- International Personality Item Pool (mini-IPIP) on Nigerian respondents. Study Design: A cross-sectional survey design was used to validate the scale. Place of Study: University of Ibadan, Oyo State, South-western Nigeria. Between January and April 2022. Methodology: A multistage sampling technique was used to select two hundred and nineteen (219) individuals, made up of 113 (51.6%) of males and 106 (48.4%) of females, between the age of 35 and 61 years with Mean age = 46.49 ± SD = 6.23. The participants included administrative, technical and junior staff working in the University of Ibadan, Oyo State, and South-western Nigeria. Participants responded to The Big Five Inventory (BFI-10) and Mini-IPIP. The internal consistencies for the Mini-IPIP was calculated and obtained using Cronbach’s (α) reliability coefficient. Also, the concurrent validity coefficient was obtained using Pearson's Correlation Analysis, Min-IPIP was correlated with BFI-10 in order to ascertain the concurrent validity. The items total correlations were also obtained to test the relationship between each item and the composite/total item score. Results: A modest but acceptable internal consistency of Extraversion, α =.80; Agreeableness, α =.79, Conscientiousness, α =.84; Neuroticism, α = .83; and Openness to Experience α =.88 for the factors of mini-IPIP was revealed. Positive concurrent validity coefficient was equally observed between the subsections of Mini-IPIP and the BFI-10 (r = .34, .12, .18, .20, .11 for extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience subscales respectively). Conclusion: These findings provide evidence for the use of Mini-IPIP scale as screening tool for the assessment of human personality in Nigeria based on the five-factor model.
