This article explores different response styles by using two scales representing attitudes toward immigrants and reunion across the Taiwan Strait. Data were collected from a face-to-face survey – the 2003 Taiwan Social Change Survey. A response style index was first used to compare response style across scales. Exploratory Factor Analysis, Latent Class Factor Model-continuous indicators and Latent Class Factor Model-nominal indicators were then used to compare the response patterns (styles) of the nine attitudinal items.
