Read the following passage and answer the questions : Ishita, a Psychometrician generated 120 items in July 2021 to develop a tool on pro-environmental behaviour with five response patterns starting from 'Strongly Disagree' to 'Strongly Agree'. She retained 85 items based upon item-total correlation. Then she verified internal consistency of the items using data collected from 800 respondents in Dec, 2021. Ms Ishita named five dimensions extracted by her through exploratory factor analysis in March 2022. Thereafter she collected data from 400 respondents and accomplished measurement model analysis through confirmatory factor analysis in Nov, 2022.
Square root of AVE (Average Variance Extracted) can be used to assess ________
Discriminant Validity Assessment Using AVE
The square root of the Average Variance Extracted (AVE) is a key metric used to assess the discriminant validity of a measurement model. Discriminant validity ensures that a construct is unique and distinct from other constructs.
Assessing Discriminant Validity
A common criterion for assessing discriminant validity is the Fornell-Larcker criterion. This method compares the square root of the AVE for each construct with the correlation between that construct and all other constructs in the model.
- If the square root of the AVE for a construct is greater than the absolute value of the correlation between that construct and any other construct, it provides evidence for discriminant validity.
- Mathematically, for a construct A and another construct B:
$\sqrt{AVE_A} > |correlation(A, B)|$
This indicates that the shared variance between construct A and itself (as measured by AVE) is higher than its shared variance with any other construct, confirming it is distinct.
Distinguishing from Other Concepts
- Composite Reliability (e.g., Cronbach's Alpha, McDonald's Omega) measures the internal consistency of items within a single construct.
- Convergent Validity assesses the degree to which two measures of the same construct are correlated.
- Inter-rater Reliability measures the agreement between two or more independent raters.
The square root of AVE specifically addresses how well a construct differs from others, which is the definition of discriminant validity.
