Development and Implementation of a Computerized Adaptative Testing (CAT) of Self-perceived Quality of Care in Psychiatry

Objectives

1. to develop and validate a Computerized Adaptative Testing (CAT) of self-perceived quality of care in Psychiatry.
2. to analyze the implementation of this new measure in clinical practice : qualitative analysis of the relationship patient/professional.

   • Elaboration of a pool of items, based on literature review and interview with patients.
   • Selection of the most relevant items based on a qualitative approach using cognitive interview with patients.
   • Calibration of the item bank : the psychometric properties of the item bank will be based on classical test and item response theories and approaches, including the evaluation of unidimensionality, item response theory model fitting, and analyses of differential item functioning.
   • Metrological validation of the CAT.

2. Analysis of the implementation of the CAT in clinical practice using interview with professionals and patients.
