Geographically Weighted Cronbach's Alpha

As individual’s cognitions and behaviours are affected by where they live, the reliability of responses to tests or scales may vary with location. In this paper, we develop a local version of Cronbach’s alpha, geographically weighted Cronbach's alpha, to investigate how the reliability of the measure varies spatially. Two demonstrations of exploratory applications of the three-wave geocoded measure of “social capital index” in the Baltimore metropolitan area, USA, was also performed in this paper.
