Background: Worldwide, type 2 diabetes mellitus (T2DM) is one of the most prevalent chronic diseases and one of those producing greatest impact on patients’ day-to-day quality of life. Our study aim is to validate the “Living with Chronic Illness Scale” for a Spanish-speaking T2DM population. Methods: In this observational, international, cross-sectional study, 582 persons with T2DM were recruited in primary care and outpatient hospital consultations, in Spain and Colombia, during the period from May 2018 to June 2019. The properties analysed were feasibility/acceptability, internal consistency, reliability, precision and (structural) content-construct validity including confrmatory factor analysis. The COSMIN checklist was used to assess the methodological/psychometric quality of the instrument. Results: The scale had an adequate internal consistency and test retest reliability (Cronbach’s alpha=0.90; intraclass correlation coefcient=0.96, respectively). In addition, the instrument is precise (standard error of measurement=3.34, with values<½SD=8.52) and correlates positively with social support (DUFSS) (rs=0.56), quality of life (WHOQOL-BREF) (rs=0.51–0.30) and ssatisfaction with life (SLS-6) (rs=0.50–0.38). The original 26-items version of the scale did not support totally the confrmatory factor analysis. The COSMIN checklist is favourable for all the properties analysed, although weaknesses are detected for structural validity. Conclusions: The LW-CI-T2DM is a valid, reliable and accurate instrument for use in clinical practice to determine how a person’s life is afected by the presence of diabetes. This instrument correlates well with the associated constructs of social support, quality of life and satisfaction. Additional research is needed to determine how well the questionnaire structure performs when robust factor analysis methods are applied.
