| Abstract | The theta (θ) coefficient is an index of internal consistency for a composite score. It was proposed in the 1970s by David J. Armor as an alternative measure of internal consistency in tackling several problems encountered by the alpha (α) coefficient, which had been introduced in the 1950s by Lee J. Cronbach. Theta reliability can be interpreted as an alpha coefficient maximized by using optimal weights in creating a composite score. It is directly related to principal component analysis. In this article, a real example is offered to demonstrate the procedure for estimating the theta coefficient, and how these procedures contrast against those used for estimating the alpha coefficient is discussed. |
