Query: Transportability of Outcome Measurement Error Correction: from
  Validation Studies to Intervention Trials   Many lifestyle intervention trials depend on collecting self-reported
outcomes, like dietary intake, to assess the intervention's effectiveness.
Self-reported outcome measures are subject to measurement error, which could
impact treatment effect estimation. External validation studies measure both
self-reported outcomes and an accompanying biomarker, and can therefore be used
for measurement error correction. Most validation data, though, are only
relevant for outcomes under control conditions. Statistical methods have been
developed to use external validation data to correct for outcome measurement
error under control, and then conduct sensitivity analyses around the error
under treatment to obtain estimates of the corrected average treatment effect.
However, an assumption underlying this approach is that the measurement error
structure of the outcome is the same in both the validation sample and the
intervention trial, so that the error correction is transportable to the trial.
This may not always be a valid assumption to make. In this paper, we propose an
approach that adjusts the validation sample to better resemble the trial sample
and thus leads to more transportable measurement error corrections. We also
formally investigate when bias due to poor transportability may arise. Lastly,
we examine the method performance using simulation, and illustrate them using
PREMIER, a multi-arm lifestyle intervention trial measuring self-reported
sodium intake as an outcome, and OPEN, a validation study that measures both
self-reported diet and urinary biomarkers.
