Development and Validation of the Diabetes Pen Experience Measure: A New Patient-Reported Outcome Measure.

ABSTRACT:

Background

Satisfaction with insulin-delivery devices has been shown to improve treatment adherence, translating into better glycemic control. The Diabetes Pen Experience Measure (DPEM) is a new patient-reported outcome measure to evaluate patients' experience when using an injection device.

Methods

The DPEM was developed using literature review and concept elicitation interviews with clinical experts and patients. This led to a theoretical model and a draft measure of the diabetes pen experience, which was refined following cognitive debriefing. Validation entailed a web-based, noninterventional survey; psychometric analyses conducted according to a statistical analysis plan; and refinement and finalization of the DPEM and theoretical model.
