The auditory alerting cue would then compensate for this decreased validity effect.
We looked to alternative methods to routinely measure compliance because human auditing has decreased validity and reliability inherent in the methodology.
We consider this to be a serious problem, as the chance to produce the expected results in experimental studies increases with decreasing validity of the studies.
Studies have investigated validity among people with cognitive impairment or dementia and have found decreasing validity along with decreasing level of cognitive function (Kørner et al., 2006; Müller-Thomsen, Arlt, Mann, Mass, & Ganzer, 2005; Smalbrugge, Jongenelis, Pot, Beekman, & Eefsting, 2008).
Older age has [ 11, 36] or has not [ 6] been associated with decreased validity of self-reports, while narrow age window in our study (57 68 years) might explain the found minimal age effect.
Inclusion of extra, non-alignable sequence in an assembly and/or expansion of repetitive sequence can both contribute to high parsimony values (the former decreases validity, the latter increases multiplicity).
While the above limitations decrease external validity of our study, including two control groups significantly strengthens internal validity.
If voting patterns can come from unconscious biases, does that decrease their validity?
This may decrease the validity of the composite score.
