Abstract

This study aims to examine the effect of addition and deletion of items on coefficient alpha. In addition, necessary assumptions for appropriate interpretation of coefficient alpha are examined. This research offers prescriptive and descriptive insights for appropriate use of coefficient alpha. [W.P. No. 2016-03-38]
