Abstract(original):
To enable reporting on a latent trait (sometimes referred to as a construct) or other abstract trait, some questions in the TALIS 2018 questionnaires were combined into an index or scale. This chapter explains how the indices were created and describes the methodology used to validate scales and construct scale scores. It details latent trait evaluation and the procedure involved in computing scale scores and illustrates the implications of the evaluation results for using scale scores in further analyses. The chapter also describes the possibilities and limitations of using scale scores for cross-country/economy comparisons and presents each scale in more detail together with its statistical properties.
