Modified version of the PCAT-A10 tool for the evaluation of primary care

Objective: To evaluate the measurement characteristics of the Spanish and Catalan versions of the 10-Item Primary Care Assessment Tool for adults (PCAT-A10), shortened from the original Primary Care Assessment Tool (PCAT), with a new mental health item. Design: Cross-sectional observational study. Location: The city of Barcelona. Participants: Of the 3,496 people over 14 years of age from the representative random sample of the Barcelona population, from the 2016-17 Barcelona Health Survey, those who declared they had a family doctor, and had visited a specialist at some time in their lives, and had answered more than 50% of PCAT-A10 items were selected (n = 3,107). Main measurements: Item descriptive analysis, analysis of internal consistency, corrected item - total correlation, of the PCAT-A10 index and the 10 items that make it up. Three scenarios for non-response to treatment were analysed: substitution by 0, by the intermediate value, and excluding people who did not answer any item. Results: The PCAT-A10 index obtained Cronbach alphas of 0.73, 0.79, and 0.85 in the three mentioned scenarios, correlation item total corrected between 0.41 and 0.66, and 20.8% nonresponses to the mental health item. Conclusions: The new version of PCAT-A10 has a high reliability with a higher response in the mental health item compared to the previous version. (C) 2019 The Authors.
