Conventional wisdom on measurement: A structural equation perspective.

TL;DR: In this paper, the applicability of five conventional guidelines for construct measurement is critically examined: (a) Construct indicators should be internally consistent for valid measures, (b) there are optimal magnitudes of correlations between items, (c) the validity of measures depends on the adequacy with which a specified domain is sampled, within-construct correlations must be greater than between construct correlations, and (e) linear composites of indicators can replace latent variables.

Practical application of the vanishing tetrad test for causal indicator measurement models: An example from health‐related quality of life

TL;DR: The vanishing tetrad test (VTT) is illustrated by looking at multiple items from a health related quality of life instrument that seem more likely to cause the latent variable rather than the other way around.
