Abstract
One way to estimate reliability, specifically the internal consistency, of FSSE results is by calculating Cronbach’s alphas and intercorrelations for the FSSE scales. Internal consistency is the extent to which a group of items measure the same construct, as evidenced by how well they vary together, or intercorrelate. A high degree of internal consistency enables the researcher to interpret the composite score as a measure of the construct (Henson, 2001). Assuming the FSSE scales effectively measure an underlying construct, we would expect to find high estimates of their internal consistency.
