A nationally-representative study design will enhance the external validity of any data in relationship to a target population of the country it is intended to represent [ 77].
Additionally, we sought concurrent validity in relationships among predictors of our survey subscales, but validity can also be sought in scales' ability to predict important outcomes (i.e., predictive ability) such as academic achievement (e.g., grades in school).
We focused on three different sources of validity: content validity, internal structure, and relationship to other variables (Downing 2003).
Any transfer of the authority of the body politic either to some part of itself or to some outside entity — the apparatus of the state, a monarch, or even the people — is illegitimate, for the validity of a government is rooted in its relationship to natural law.
To examine the factorial validity of the Contesting Orientations Scale (COS) in a large sample of intercollegiate student-athletes, as well as to extend evidence of the concurrentrrent validity by examining its relationship to autonomous and controlled motivations in sport.
We developed an instrument to measure pediatric residents' self-efficacy in CRM skills and assessed its content validity, internal structure, and relationship to other variables.
The comparative neglect of Ferguson's δ and its lack of generality have resulted in an absence of studies to elucidate its sampling distribution and other characteristics, in particular its relationship to validity, reliability and effect size.
Understanding temporal changes in PCB body burden is crucial for evaluating exposure levels and augmenting validity of studies investigating their relationship to adverse health effects.
Results indicated that the BNSS has excellent internal consistency and temporal stability, as well as good convergent and discriminant validity in its relationships with other symptom rating scales, functional outcome, self-reported anhedonia, and neuropsychological test scores.
