I am looking for other scholar opinion as i am only able to find of more than 0.50 is the minimum acceptable value.
Perhaps, maybe >0.40
In this article:
http://www.ijiet.org/papers/267-IT0040.pdf
found the following:
Average Variance Extracted (AVE) is higher than 0.5 but we can accept 0.4.
Because Fornell and Larcker said that if AVE is less than 0.5,
but composite reliability is higher than 0.6, the convergent
validity of the construct is still adequate (Fornell & Larcker, 1981)
C. Fornell and D. F. Larcker, “Evaluating structural equation models
with unobservable variables and measurement error,” Journal of
marketing research, pp. 39-50, 1981.

Thank You Mr. Han!
Really appreciate it. But i don't understand what Composite Reliability is?
Owh got it. Composite Reliability is the significant / critical ratio of 1.960. Is that correct?
Hi Mohd,
Composite Reliability is usually generated when running Structural Equation Modeling (SEM) test that is the measure for internal consistency of reliability that does not assume equal indicator loadings whereas Cronbach Alpha is the measure of internal consistency of reliability that presume equal indicator loadings (Hair, Hult, Ringle & Sarstedt, 2014).
Composite Reliability is adopted in SEM analysis as its value is usually higher than Cronbach Alpha in which the difference is inconsequential (Peterson & Kim, 2013).

Hi Mr Han Ping
I would like to get your opinion about Cronbach Alpha ? what is the minimum accepted value ? Can you please share some articles to support my results because I have obtained from SmartPls analysis for Cronbach Alpha result 0.61, 0.57 & 0.45.
Thank you in advance
Thank you Dr Han. I was in the situation where AVE values were below .5 but CR values are above .8. Your contribution has helped me a lot.
Nashwan AL-Emad , literature suggest 0.6 as the minimum acceptable value for Cronbach Alpha

Thanks for the contribution. It´ll help me on my thesis results.
do I need to calculate both CR & Cronbach Alpha ? or CR is enough
i need your opinions . thank you
Dear all,
sorry to drop in like that but i am trying to understand the meaning of critical value of composite reliability
I am getting always a value of 1
is it important to keep while interepreting my results
what does it mean
thank you
Thank you Mr. Han. I have two AVE values below 0,5 and your suggestion helps me a lot
The acceptable AVE value must be greater than 0.50 .( Fornell & Larcker, 1981 )
The value of AVE depends on the value of factor loading. Therefore, if the AVE value is below 0.5 (Fornell and Larcker, 1981), would be advisable to check the factor loading for each items. Any item has loading below 0.4 should be dropped (see Kline 2005 or Hair et al., 2006 and other statisticians). However, from past experience, if you use SEM, the CFA result would supersede the EFA.
