PSYC 3250 Chapter Notes - Chapter 8: Face Validity, Convergent Validity, Discriminant Validity
Provides a definition in terms of concrete behaviours o i. e. aggressiveness reflected in assaulting a classmate. The stronger the match b/w expected correlations and actual correlations, the stronger evidence of construct validity. Cv depends on a detailed description of relationship b/w construct and a number of different behaviours. An implication is that it"s easier to determine cv for measures of well-defined constructs than those loosely defined: can"t tell if given test provides a good measure of the construct if only have a fuzzy idea of. Validity and measurement: content and construct orientation validation strategies. Goal of construct validation is to determine whether test scores provide a good measure for specific what construct means. Determining appropriate methods for studying cv depends on the construct we wish to measure. Campbell and fiske (1959) noted that if we use a number of methods to measure more than one trait, the correlations among the measures will take form of a multitrait-multimethod matrix: ex.
