The Patient Assessment of Chronic Illness Care (PACIC) instrument, developed by Glasgow in 2005, assesses from the patient’s perspective, how far care by health care professionals is congruent with the Chronic Care Model (CCM).
Several studies have performed validation analyses of the PACIC, showing wide variations of the psychometric properties across diseases, languages and populations.
Whereas some authors agreed on the one-dimensional structure of the instrument, they did not all agree on the number of items to include: all 20 items or less such as proposed in shorter versions of the PACIC.
Up to now, most PACIC validation studies were based on factor analyses and focused on the PACIC’s dimensional structure.
With the present study we want to go a step further and investigate additional psychometric properties using Rasch models (parametric Item Response Theory (IRT) model).
