Acceptability and psychometric properties of four scales assessing the impact of Type 2 diabetes on quality of life—Results of ‘YourSAY: Quality of Life’
Authors' conclusion
The current study provides novel insights into the acceptability, validity and reliability of diabetes-specific QoL measures for adults with T2D. Consistent with the published Type 1 diabetes cohort findings, the DIDP is recommended as a brief, acceptable and psychometrically sound measure. However, selection needs to be considered in the context of the specific research or clinical aims and further evidence (e.g. responsiveness) may be required before it can be recommended for use in trials or prospective studies.
