Convergence validity: Yes, rRD1,RD2 = 0.419** and rIP1,IP2 = 0.520** are really high and significant; 
Discriminant validity: Yes, rRD1,RD2 = 0.419** and rIP1,IP2 = 0.520** >> |rRD1,IP2| = 0.017 and |rIP1,RD2| = 0.294**
Construct validity without either a combination of trait and method effects or a mono-method bias: Yes, rRD1,RD2 = 0.419** and rIP1,IP2 = 0.520** >> |rIP1,RD1| = 0.182 and |rRD2,IP2| = 0.320**
