The Patient Assessment of Chronic Illness Care questionnaire: evaluation in patients with mental disorders in primary care.

The Chronic Care Model provides evidence-based recommendations to improve the care for patients with chronic conditions. The Patient Assessment of Chronic Illness Care questionnaire (PACIC) is an instrument to evaluate the patient's perspective on receipt of care delivered in the five domains patient activation, delivery system, goal setting, problem solving, and follow-up. The aim of this study was to assess the psychometric characteristics of the PACIC in 442 primary care patients with major depression. The psychometric properties were good. We found possible ceiling effects in the two subscales 'patient activation' (12.9%) and 'problem solving/contextual' (8.9%), as well as floor effects in 'goal setting/tailoring' (4.6%). The Cronbach's α coefficient for the total scale was excellent (0.91). We found two major factors, which we labeled according to the PACIC domains as composite factors 'patient activation and problem solving' as well as 'goal setting and coordination'. The perspective of patients with mental disorders, such as depression, on primary chronic illness care can be assessed adequately by the PACIC.
