Understanding and Solving Discriminant Validity Issues.

We have now assessed the discriminant validity. However, a number of time scholars face issues in establishing discriminant validity. The two session specifically focus on how to solve discriminant validity issues. 

Considerations before Collecting the Data

  • Make sure to have adequate No. of Items in each scale/construct.
  • There should be at least 4-6 items, since, in SEM items are deleted if they fail to load or due to cross-loading.
  • Make sure that the Items/Statements are easy to understand.
  • Make sure there is no overlap in the statements of different constructs.

How to Solve Discriminant Validity Problems?

To solve the discriminant validity issues, following steps may be undertaken

  • Make sure to clean the data.
  • Check for Standard Deviation in Responses. Standard Deviation value of Less than 0.25 mean that there is probability of respondent misconduct and the responses for the questions are almost similar.
  • Assess cross-loading, if an item is loading well onto another construct instead of its own construct, that particular items shall be removed. For example, an item has loading over 0.70 on two constructs
  • Check for Cross-loading, if an item is cross-loading, and the difference is less than .10, REMOVE the item(s).
  • Check for low loadings, remove items that have low loadings (start with < 0.40).
  • If the problem still persists,–try collecting more data
  • –Combine the constructs that have lack of discriminant validity as they are measuring the same concept (This is appropriate for dimensions of the same construct).
  • If problems still persist, dropping one (or more) independent variables (i.e., collinear variables that demonstrate insufficient discriminant validity) from the model may also help.
