Complex Constructs and Item Selection

Presentation from AERA 2019 with Karen Nylund-Gibson and Michael Furlong

Using self-report survey items administered to 1,908 high school students, it is shown via latent class analysis with distal outcomes that a researcher would likely come to the same conclusions whether using a one item measure of life satisfaction or several items traditionally used to measure subjective well-being (SWB). This research emphasizes the difficulties of being able to make between-person measurement claims in the realm of self-report surveys, in general.
