Average variance extracted (AVE) values were used to determine whether or not convergence validity and discrimination validity were verified (Fornell & Larker
, Richardson, and Tuna (2007) found no evidence of a link between directors' age and financial performance measured by return on assets (ROA) or future stock returns.
In determining discriminant validity, the squared correlation between two constructs must be less than either of their individual AVEs (Fornell and Larker
This was done using the suggested procedure of Fornell and Larker
Get West London photographer Grahame Larker

De acordo com Ringle, Silva e Bido (2014), deve-se usar o criterio de Fornell e Larker
(Henseler et al., 2009), cujo valores de referencia da AVE devem ser iguais ou superiores a 0,50 (AVE's > 0,50).
The cut off values exceeding 0.50 in respect of both AVE and construct reliabilities are considered significant to ensure the convergent validity (Fornell & Larker
, 1981; Bagozzi & Yi, 1991; Hair et al., 2006).
Para evaluar la validez convergente, Fornell & Larker
(1981) sugieren el uso de la varianza media extraida (AVE).
A consistencia interna do instrumento foi avaliada pelo alfa de Cronbach (MESSICKS, 1995) e pela fiabilidade composita (FORNELL; LARKER
