Assessment of Usefulness and Validity of IDSQ-J with Subanalysis Focusing on Insulin Pen Devices

Abstract

The Japanese version of the insulin delivery system questionnaire (IDSQ-J) is a scale rating insulin injection devices. We retrospectively subanalyed the data used to develop the IDSQ-J. We found that lifestyle impact is an important factor in the user's view of quality of life (QOL) relating to insulin delivery devices. The IDSQ-J is useful for evaluating the insulin delivery of users in daily social activities. The IDSQ-J is a reliable, valid rating scale in addition to being clinically useful in evaluating insulin delivery from the user's viewpoint.
