We used the known-groups method (9) to examine the construct validity of the HINT to address this research aim. Construct validity is measured by the extent to which hypotheses--suggested by theory and prior research about the relationship between a target construct and other possible constructs--are supported by data. Construct validity is established for a measure with the gradual accumulation of evidence from different sources over time, and each type of evidence presented above is pertinent to the inclusive, integrative concept of construct validity (Anastasi & Urbina, 1997). |
