Psychosocial predictors of medication adherence among patients with type 2 diabetes

A study was designed with the aims of estimating the prevalence of patients with medication adherence problems, and studying the association between the number of adhesion problems and socio-demographic variables, clinical variables, illness perception and support social. For this purpose, a probability sample of 289 patients treated in the Diabetes Clinic of the Medical Service of the Autonomous University of Nuevo Leon (UANL), Mexico, was selected. A scale of medication adherence, a questionnaire of illness perception and two social support scales were applied to this clinical sample. The results showed that the prevalence of problems of adherence to treatment was significant. Medication adherence was predicted by greater perceived improvement owing to treatment and by being older. This model had a close fit to the data by the Maximum Likelihood method. It is concluded that the medication that produces improvement perceived by the patient is the most important variable to predictive the medication adhesion.
