This method paper analyzes validity evidence of the Design Thinking Mindset Questionnaire and extends the capacity of researchers and practitioners to measure design thinking. Specifically, this project investigates the potential development of design thinking mindset among secondary students by appraising the validity of an existing design thinking mindset survey when used in the secondary-education context. Despite its importance, design thinking is invisible like other forms of cognition, presenting difficulty when monitoring students’ development as design thinkers. Dosi et al. (2018) worked on measuring design thinking mindset resulting in a 71-item instrument to assess design thinking mindset based on 22 constructs. Our ongoing research involves design thinking mindset and we had interest in the questionnaire. However, differences between the present administration and the original use of the questionnaire warrant further investigation of the validity of the measurement tool. To examine the instrument’s validity, we apply exploratory factor analysis and confirmatory factor analysis to compare the originally prescribed factor structure and an empirically obtained model. These findings offer insight about the stability of the latent structure of design thinking mindset and the utility of the assessment tool in this context. By verifying the quality of the instrument in a secondary education context, researchers and practitioners may be better equipped to determine changes in this mindset among secondary students who are beginning their journey as designers.
