Flashcards in Study Guide 11: Construct Related Evidence Deck (12):
Campbell & Fiske (1959):
developed multitrait-multimethod matrix
degree to which test scores are correlated with tests of related constructs
Cronbach & Meehl (1955)
developed the idea of nomological network to give meaning and structure to constructs
degree to which test scores are uncorrelated with tests of unrelated constructs
Known groups validity or contrasted group studies
validity is determined by the degree to which an instrument/test can demonstrate different scores for groups known to vary (or not vary) on the variables being measured.
Method effects or common method variance:
Occurs when HTMM correlation > HTHM correlation and shows that use of the same method will inflate the correlation effect.
Multitrait-multimethod matrix (MTMM):
Provides guidelines for evaluating construct validity.
By considering the effects of trait and method variance on correlations among measures, researchers can gauge quality of convergent and discriminant validity evidence.
interconnection between a construct and other related constructs (correlations), embedded in theoretical context
Quantifying construct validity (QCV):
quantifying the degree of “fit” between theoretical predictions for convergent and discriminant correlations and actual sets of correlations obtained.
R2 (or r2):
squared correlation – sometimes interpreted as being the proportion of variance in one variable explained by another variable. Criticized for sometimes being statistically incorrect, non-intuitive metric, and minimizing the importance and magnitude of correlations.
correlation between test scores and highly relevant variables
