dc.description.abstractTest anxiety is a psychological variable that diversely impacts academic test performance. Test anxiety tools are developed to understand and predict its impact in different test settings. It is important to determine the reliability and validity of these tools to affirm the measures they provide. Additionally, where computers have been used in testing, there is a further need to assess the impact of test anxiety accurately. The purpose of this study was to find out the psychometric properties of the 10-item Westside Test Anxiety Scale (WTAS) that was adapted for use in Kenya. The study also investigated the effect of test mode on test anxiety. The study sample comprised 424 male and female pupils in public primary schools in Nairobi, Kenya. In a between-groups experimental set-up, 208 pupils were assigned randomly to sit a computerbased science test, and 216 pupils were assigned to the paper-based version. The WTAS was thereafter administered to pupils in both groups. An analysis of the test anxiety tool revealed adequate internal consistency and person reliability estimates. The tool also fulfilled the key Rasch model assumptions of local independence. Though all the items fitted the Rasch model, three items had disordered categories. Exploratory factor analysis revealed two additional test anxiety factors. An independent sample t-test showed that test mode had a small and insignificant effect on test anxiety. The study recommended that future studies consider developing localized test anxiety tools rather than adapting from foreign sources. Keywordsen_US
