THE VALIDATION OF THE TEN-ITEM PERSONALITY INVENTORY (TIPI) IN THE NIGERIAN SAMPLE

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 was 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 30.1064. The standard deviation of their age is 5.88177. Three instruments were employed in the research. They were Ten-Item Personality Inventory (TIPI), forty-four-item Big-Five Personality Inventory and Neuroticism domain (Domain J) of the SCL 90. The design of the study is cross-sectional and 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 627** (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 271**,.419** ,.436** , .163** and .251** (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 -.428**, -.243**, -.047, .447** and -.505** (p<0.01) significant level. Finally, on reliability, TIPI is reliable within the acceptable protocol with Cronbach Alpha of r=.71 and Split-Half of r=.76.a
