Resum:	The Diabetes Health Profile (DHP-18), structured in three dimensions (psychological distress (PD), barriers to activity (BA) and disinhibited eating (DE)), assesses the psychological and behavioural burden of living with type 2 diabetes. The objectives were to adapt the DHP-18 linguistically and culturally for use with patients with type 2 DM in Ecuador, and to evaluate its psychometric properties. Participants were recruited using purposive sampling through patient clubs at primary health centres in Quito, Ecuador. The DHP-18 validation consisted in the linguistic validation made by two Ecuadorian doctors and eight patient interviews. And in the psychometric validation, where participants provided clinical and sociodemographic data and responded to the SF-12v2 health survey and the linguistically and culturally adapted version of the DHP-18. The original measurement model was evaluated with confirmatory factor analysis (CFA). Reliability was assessed through internal consistency using Cronbach's alpha and test-retest reproducibility by administering DHP-18 in a random subgroup of the participants two weeks after (n = 75) using intraclass correlation coefficient (ICC). Convergent validity was assessed by establishing previous hypotheses of the expected correlations with the SF12v2 using Spearman's coefficient. Firstly, the DHP-18 was linguistically and culturally adapted. Secondly, in the psychometric validation, we included 146 participants, 58. 2% female, the mean age was 56. 8 and 31% had diabetes complications. The CFA indicated a good fit to the original three factor model (χ2 (132) = 162. 738, p < 0. 001; CFI = 0. 990; TLI = 0. 989; SRMR = 0. 086 and RMSEA = 0. 040. The BA dimension showed the lowest standardized factorial loads (λ) (ranging from 0. 21 to 0. 77), while λ ranged from 0. 57 to 0. 89 and from 0. 46 to 0. 73, for the PD and DE dimensions respectively. Cronbach's alphas were 0. 81, 0. 63 and 0. 74 and ICCs 0. 70, 0. 57 and 0. 62 for PD, BA and DE, respectively. Regarding convergent validity, we observed weaker correlations than expected between DHP-18 dimensions and SF-12v2 dimensions (r > −0. 40 in two of three hypotheses). The original three factor model showed good fit to the data. Although reliability parameters were adequate for PD and DE dimensions, the BA presented lower internal consistency and future analysis should verify the applicability and cultural equivalence of some of the items of this dimension to Ecuador.
