Person distribution for ‘Emotional Representations’ Scale.
A large group of patients, represented by bars above the x-axis, fall between −1.6 and −3.2 logits, which were outside the measurable range of the scale, represented below the x-axis of the figure.

Category response thresholds for item 30.
Disordered response thresholds are evident for item 30.

Category response options for item 26.
Following rescoring, response thresholds are correctly ordered for item 26.
Figure 4.
Illustration of logit (i.e. perceived importance of multimorbidity) value for each subtest in the Summary scale.
When measured along the same linear continuum (perceived importance of multimorbidity) mean location of each subscale can be directly compared. By convention, in Rasch analysis the Summary Scale is centred around zero logits.
