Development and calibration data for the Illness Burden item bank: a new computer adaptive test for persons with type 2 diabetes mellitus.

ABSTRACT:

Purpose

The purpose of this study was to develop a new measure, the Re-Engineered Discharge for Diabetes Computer Adaptive Test (REDD-CAT) Illness Burden item bank, to evaluate the impact that a chronic condition has on independent living, the ability to work (including working at home), social activities, and relationships.

Methods

Semi-structured interviews were used to inform the development of an item pool (47 items) that captured patients' beliefs about how a diagnosis of type 2 diabetes interferes with different aspects of their lives. The Illness Burden item bank was developed and tested in 225 people with type 2 diabetes mellitus.

Results

No items had sparse response option cells or problems with monotonicity; two items were deleted due to low item-rest correl
