Establishing the psychometric properties of self-reported scales and constructs is vital to social and behavior sciences. This task is more challenging for researchers interested in within-person variability. The psychometric qualities of within-person variability require statistical approaches that differ from traditional between-person approaches. This chapter provides a description and tutorial on how to assess the reliability, factor structure, and discriminant validity of a construct simultaneously at the between- and within-person levels of variability using the example of daily cognitive interference.
