You need to check for Convergent validity ( Average Variance Explained (AVE) where is the value for each factor should above 0.50), and Discriminate validity . According to Fornell and Larcker’s To assess the discriminant validity, , that square root of the AVE for each construct should be greater than the correlation between constructs.
