Validity and Reliability of the Nine Scales
This chapter reports the validity and reliability of the nine scales using the Essential Servant Leadership Behaviors (ESLB) scale to test for convergent validity, Cronbach alpha scores for scale reliability, and pre-post t-tests to show test-retest reliability. Pearson r scores for the nine scales which ranged from .83 to .91 demonstrated strong correlations. Cronbach alpha scores ranged from .92 to .98 showing strong scale reliability. The pre-post t-tests showed no significant difference between the pre- and post-tests. The chapter recommends future research studies to further test for validity and leadership development longitudinal studies to test changes in scale results over time.
