Abstract

This study aims to investigate double monotonicity of Revised Clinical Interview
Schedule (CIS-R) psychiatric status rating scales data from 2007 Adult Psychiatric
Morbidity Survey (APMS) within the framework of Mokken models. Results show that the items of the scale are sufficiently unidimensional in the general population for the CIS-R responses to be scalable according to broad Mokken principles. These do not require recourse to the parametric models for item response function curves typical of most applications of IRT in patient reported outcome measures research (PROMs). Our illustrative results provide an exemplar of the method. The methods are however more widely relevant for phenotype work in clinical and behavioural research, and so should appeal to those who work on addictions or in clinical medicine.
