Resumen en inglés

Therapeutic adherence depends on the behaviors adopted by people with diabetes and their families, to avoid chronic complications, which can affect their quality of life, generating in them social and economic consequences. In order to design and validate an instrument to identify therapeutic adherence in patients with type 2 diabetes mellitus, a methodological study was carried out. The effective communication process to build consensus group Delphy Method was used to measure the facial validity and content of the instrument to measure therapeutic adherence in patients with type 2 diabetes mellitus. (AT-DM2) Modifications were made, 10 on the second measurement formed by professionals of different professions associated with the Diabetes control program, and twelve experts on the third one. Statistical analysis reported a median of 3.4, interquartile range of 0.4. The Cronbach alpha reliability psychometric tests 0.86 rates it very high. The Factor analysis using the Varimax rotation or normalization method identified the highest values of variance. These were grouped into 5 factors which accumulated the 89.23% of the variance with eigenvalues close to one. The factors are: "knowledge about self-care", "family support", “socio-cultural and economic environment influence” “personal commitment for therapeutic compliance” "Influence of education on therapeutics compliance". The final instrument consisted of two dimensions: "related to the patient and his environment" and "related to health care" and 20 items that can qualify clinical adherence and be used for research purposes.
