WebIf your measures are not $\tau$-equivalent, then $\alpha$ will underestimate reliability, regardless if the data are continuous or dichotomous.

WebThe example shifts the continuous latent (X*,Y*) distribution to the right along the x-axis (not changing the shape of the latent distribution at all), and finds that the Pearson correlation between (X,Y) decreases as we do so. For this reason, you might consider using the tetrachoric correlation for dichotomous data, if it is feasible to estimate.
