Pearson correlation for validity between the Semantic Differential Power Perception (SDPP) Survey and the Sources of Power (SOP) Audit.

Validity of the SDPP Survey (n = 13)
	Informational		Expert		Referent		Legitimate		Reward/Coercive
Number of Word Pairs	Original	Reliable	Original	Reliable	Original	Reliable	Original	Reliable	Original	Reliable
Number of Word Pairs	4	3	5	4	7	5	5	4	5	4
Pearson Correlation	0.79	0.57	0.66	0.68	0.72	0.74	0.63	0.81	0.81	0.51^*
Correlation Strength	Strong	Moderate	Moderate	Moderate	Strong	Strong	Moderate	Strong	Strong	Moderate

Moved a word pair from the Reward/Coercive Power Base to the Legitimate Power Base to improve the reliability of the Legitimate Power Base even though it decreased the reliability and validity of Reward/Coercive. However, Reward/Coercive remained above the acceptable threshold for both reliability and validity.
