Abstract

Although there is no doubt that Likert scaling suffices for straightforward scale development and use, it is important to appropriately model the response process for more complex measurement problems. In this response, we comment on the response process and four applications: assessment of dimensionality, computerized adaptive testing, differential item functioning, and individual differences in responding. In each case, we argue that correctly modeling the psychology of responding is critical.
