Coefficient alpha (α) was first introduced by Lee J. Cronbach in 1951 and since then it continues to serve as a valuable index of reliability within different areas of research. According to the Social Sciences Citation Index, between 1951 and 2010, Cronbach’s seminar article (Cronbach, 1951) was cited 6,912 times by other published articles and numerous other publications often cite secondary sources in support of the use of coefficient alpha.
