This paper reports an application of Samejima’s
latent trait model for continuous responses. A brief
review of latent trait theory is presented, including
an elaboration of the theory for test responses other
than dichotomous responses, in order to put the
continuous model in perspective. The model is then
applied using the Impulsivity and Harmavoidance
scales of Jackson’s Personality Research Form.
Special attention is given to the requirement that
the model be invariant across populations and sex
groups. Results showed that responses from males
fit the model better than those from females, especially
for the Harmavoidance scale. The practical
and theoretical implications of the study are discussed.
