Development of computerized adaptive tests for psychopathology for use of general practitioners in the Northern Netherlands

Psychometrics and Statistics

The role of the General Practitioners (GP’s) in the process of delivering mental health services in the Netherlands is changing. GP’s are expected to fulfill the task of a ‘gate-keeper’ by deciding which patients are referred to primary health institutions and which are referred to specialized mental health care (triage). Furthermore, they are expected to handle more cases themselves, with the aid of a practice nurse. All in all, they are receiving more responsibility in the process of triage. In order to be able to meet those new requirements, GP’s have expressed a need for more support from standardized diagnostic instruments. Unfortunately, the instruments that have been developed so far for the purpose of triage are not empirically based and are not validated. Other instruments that have not been developed specifically for triage are unnecessarily long and therefore time consuming. The current research project focuses on the construction, integration and validation of several computerized adaptive tests (CATs; based on Item Response Theory (IRT)) that tap distinct mental health problems that are relatively frequently encountered by GP’s in the Netherlands. The goal of the current project is to apply CAT to develop an adaptive screener.
