Eighteen years of research using the Happiness Measures (HM) is reviewed in relation to the general progress of well-being measurement efforts. The accumulated findings on this remarkably quick instrument, show good reliability, exceptional stability, and a record of convergent, construct, and discriminative validity unparalleled in the field. Because of this, the HM is offered as a potential touchstone of measurement consistency in a field which generally lacks it.
