Reliability of Scale(s):

In two studies testing the median internal consistency reliabilities of the JPI-R the results were .90 and .93. Correlations indicated that the subscales correlate higher on average with their own score than any of the total scores of the other 14 subscales.

Validity of Scale(s):

Several studies have been conducted in the past that demonstrate the validity and broad capabilities and applications of the JPI-R. Hundreds of correlations of JPI-R subscales with varying criteria, ranging from relationships with dimensions of executive performances to occupational preferences, support the validity of the JPI-R. In addition, correlations between the JPI-R and several well-known measures of personality provide evidence of convergent and discriminant validity.
