Abstract
Aims
To 1) evaluate information provided on the latent diabetes distress trait when using the Problem Areas In Diabetes, 20 item (PAID-20), PAID-11 or PAID-5, and 2) evaluate the information provided by each scale item.
Methods
Using nationwide registry data from 10,190 individuals with type 1 diabetes in Norway, we applied Item Response Theory (IRT) analyses to compare test information curves for PAID-20, PAID-11, PAID-5 and their scale items.
Results
The test information curve for PAID-20 captured an overall broader range of the latent distress trait compared to the other versions. At test information level ≥ 10, the ranges (SD under/above mean) were: PAID-20: −1.30 to 3.32; PAID-11; −1.17 to 2.76; and PAID-5: −0.59 to 2.27. Six PAID-20 items had flat information curves with limited contribution to the latent trait, whereas the PAID-11 included 11 of the 12 items most frequently reported as serious problem areas.
Conclusions
The PAID-20 captures most information on the latent diabetes distress trait; however, the PAID-11 provides comparable information and captures the most serious problem areas. The PAID-5 provided limited information and covers limited aspects of distress. Overall, the PAID-11 may be a good choice for assessing diabetes distress in both research and clinical practice.
期刊介绍:
Diabetes Research and Clinical Practice is an international journal for health-care providers and clinically oriented researchers that publishes high-quality original research articles and expert reviews in diabetes and related areas. The role of the journal is to provide a venue for dissemination of knowledge and discussion of topics related to diabetes clinical research and patient care. Topics of focus include translational science, genetics, immunology, nutrition, psychosocial research, epidemiology, prevention, socio-economic research, complications, new treatments, technologies and therapy.
