Abstract or Summary

In this report, we record the process we followed in designing the Personal Agency and Self-Efficacy Rating Scale (PASERS). We outline how we progressed from the general concept of a rating scale to a theory-informed account of the constructs to be measured and how we converted these into test specifications and rating scale statements. We present findings to support our claim that the PASERS has a relatively high level of internal consistency (i.e. reliability). We explain how we used reliability analysis (alpha coefficients) to argue a case for the design. We then proceed to a section on the construct validity of the tool, specifically how principal components analysis can be used in reducing the number of items in the scale. We concluded that although a theory-informed approach was useful in selecting constructs and formulating rating scale items, PCA was a useful supplementary tool to cross-validate how item responses were configured for small cohorts of learners. These configurations then allowed us to re-interpret what the items had tested in relation to each cohort. Finally, we provide a tentative account of how we could potentially use the results to support learners. We conclude that the process of refining the measuring instrument would be on-going and cohort-specific. We viewed the rating scale as having adequate validity and reliability for us to proceed to practical implementation.
