Resumé

AIMS: To investigate the validity and reliability of the 6-item DAWN2 Impact of Diabetes Profile (DIDP), and the modified 7-item DIDP, which includes assessment of dietary freedom.

METHODS: The online, cross-sectional, Australian MILES-2 survey included the DIDP and other validated measures, to examine convergent, discriminant and known-groups validity. The DIDP was completed by 2,207 adults with diabetes (Type 1: n=1,012; Type 2 insulin: n=504; non-insulin: n=691). Data were subjected to exploratory factor analysis, internal consistency reliability and univariate statistics, conducted separately by diabetes type/treatment.

RESULTS: The DIDP was highly acceptable: 99% completion rate. One-factor solutions were supported for the 6-item and 7-item DIDP scales, in all diabetes type/treatment groups (variance explained range: 6-item: 59%-67%, 7-item: 55%-62%), with satisfactory internal consistency (α=0.85-0.90). Known-groups validity was demonstrated, by diabetes type and complications presence/absence, as was satisfactory convergent and discriminant validity.

CONCLUSIONS: The DIDP meets the need for a brief, contemporary, valid and reliable measure of the perceived impact of diabetes on quality of life, suitable for adults with Type 1 or Type 2 diabetes mellitus. The 6-item and 7-item scales have psychometric equivalence. Use of the seventh item can be informed by research questions.
