A comparative analysis of 2-option and 3-option response formats for computerized work aptitude test

This study aims to identify the optimal response format for a work aptitude test by evaluating its psychometric properties. This study employed a quantitative, quasi-experimental method utilizing a post-test only control group design. Following data cleaning, a total of 45 participants, divided into two groups, were included in the final analysis. The instruments utilized were the Focusync Test, administered with both 2-option and 3-option response sets, and the Pauli Test. The results revealed that the 3-option format demonstrated higher reliability, as indicated by Cronbach’s alpha, in measuring aspects such as total responses, errors, and variability, compared to the 2-option format. Nevertheless, the 3-option response format showed more adequate convergent validity than the 2-option format. Therefore, the 3-option response format is recommended for future computerized work aptitude tests.
