Predictive validity is a measure of whether a test (eg, IQ) predicts performance on a related criterion. Different from construct validity, which looks at how well tests relates to the concept intended. IQ has construct validity issues because of diasaggreemnt about what it is.
Construct validity is "the degree to which a test measures what it claims, or purports, to be measuring." In the classical model of test validity, construct validity is one of three main types of validity evidence, alongside content validity and criterion validity. #EDU7270
Construct validity, test-retest reliability and repeatability (Bollinger et al, 2018)
Romanian deadlift (RDL)
3 x 5 maximal effort repetitions for each exercise.

I think that assumes the scale in question has good construct validity. How can 50 different measures of health literacy (for example) all have good construct validity, and even if they did, what is the point of having so many? Why not just have one good one for each construct?
Garmin running watch equipped w/ an accelerometer strap can provide a valid measure of leg & vertical stiffness. Construct validity is greatest at fastest running speeds (5:45 min/mile pace) & at habitual training pace. Presented @APTAcsm in Washington D.C. Paper out soon.pic.twitter.com/tN4fuaUyop
Now I really want to write a paper about the construct validity of experimental manipulations just so I can have the heading "Conclusion: Making Causal Inferences on the Basis of Experimental Data is Very Hard" and give this the twin it deserves
Sharon Inouye presenting on behalf of Anne Racine at @NIDUS_Delirium symposia at #ADS2018. BASIL Study- Scale to measure delirium burden. Details in 2018 Gerantologist. Decent construct validity and good reliability. Great area that needs to be explored as outcome pic.twitter.com/76TijxxQBb
(5) There are no inherent differences between the strategies used for construct validity research and those for other kinds. Construct validity research is a bit more "basic" in that most research implicitly rests on claims about the construct validity of measures
