Preliminary Validation of Ten-Item Personality Inventory in a sample From Nsukka in Southeastern Nigeria

Abstract

This study examined the validation of the Ten-Item Personality Inventory (TIPI) in the Nigerian sample. A total of 517 students from University of Nigeria, Nsukka served as the participants in the study; 252 of them, representing 49% were males and 265 in number representing 51 % of them were made up of females. Their ages ranged from eighteen (18) to thirty-five (35) years and their mean age is 30.12 years. The standard deviation of their age is 5.88. Three instruments were employed in the research. They are; Ten-Item Personality Inventory, forty-four-item Big-Five Personality Inventory and Neuroticism domain of the SCL 90. The study is cross-sectional design. Factor analysis, pearson correlations, cronbach alpha and split-half reliabilities were adopted as the standard tools for testing the hypotheses. The results indicated that TIPI has construct validity at 63 (p<.001) significant level. On concurrent validity, the five domains of TIPI concurred with the five domains of the forty-four-item Big-Five Personality Inventory at .27,.42^,.44, .16 and .25 ⁽p<.001) significant level. On discriminant validity, the five domains of TIPI discriminated with Neuroticism domain of the SCL 90 except the Emotional Stability domain at -.43, -.24, -.05, .45    and -.51(p<0.01) significant level. Finally, on reliability, TIPI is reliable within the acceptable protocol with cronbach alpha of r = .61 and Split-half of r = .67.
