Single-item Measures: The orphaned nephew, living in the cupboard under the stairs, of measurement
The knee-jerk reaction that all single-item measures in some respect imply a weak research design is counterproductive, and serves to limit advancements in the organizational sciences. Beyond providing an off-the-shelf compendium of single-item measures for scholars and practitioners we demonstrate that 82% (75 of the 91) single-item measures under consideration in our program of research demonstrated very good or extensive validity, evidencing moderate to high content validity, no usability concerns, moderate to high test-retest reliability, and extensive criterion validity.
