Definition
Convergent validity is a supporting piece of evidence for construct validity. The underlying idea of convergence validity is that related construct’s tests should be highly correlated.
Description
Convergent validity is one of the topics related to construct validity (Gregory, 2007). Convergent validity states that tests having the same or similar constructs should be highly correlated. Two methods are often applied to test convergent validity. One is to correlate the scores between two assessment tools or tools’ sub-domains that are considered to measure the same construct. In intelligence research, two intelligence tests are supposed to share some general parts of intelligence and at least be moderately correlated with each other. Then, moderate to high correlation shows evidence of convergent validity (Gregory, 2007). The other method is the multitrait-multimethod matrix (MTMM) approach. It includes the correlations between multiple constructs and multiple measuring...
