Is the value of AVE less than but close to 0.5 acceptable?
Though AVE value must be greater than 0.5, yet the question is can i go ahead with further calculations if AVE is close to 0.5. (Little less than 0.5)...All other values, like factor loading, SCR, data adequacy etc is coming under the acceptance zone?
I had previously similar problems, what suggested to me by using one quotation related to AVE is " strict evaluation" for validity analysis. Looking at other reliability values, it would be fine. Hope at least give you an idea.
I am also facing the same issue of having all model fit indices and other measures of reliability and validity correct but my AVE is low (0.4-0.49) for my constructs. Whereas the cronbach alphas and composite reliabilities are above 0.7. Can anyone provide me a reference as to how to justify the low AVE ? Or anyother method which can help.
If p vc() is less than .50, the variance due to measurement error is larger than the variance captured by the construct -q, and the validity of the individual indicators (y,), as well as the construct (-q), is questionable.
It is strongly recommended to conduct a EFA first to assess the variables you obtained then go on with CFA. In EFA, generally, it is widely accepted that items with factor loadings less than 0.5, and items having high factor loadings more than one factor are discarded from the model. It can filter obtained model via EFA. The final model must fit with the data. All the items after run the CFA give the effect to the factors and the factors is not redundant to each other. Reliability also must be achieved in every measurement model. It could be achieved based on several criteria. If AVE is less than 0.5, but composite reliability is higher than 0.6, convergent validity of the construct is acceptable.
AVE is a strict measure of convergent validity because consideration of CR only will conclude that the convergent validity of a construct is adequate, even if more than 50% of the variance is due to the error.
