Objectives
to verify the face validity, criterion-related validity and the reliability of two distinct forms of presentation of the instrument Measurement of Adherence to Treatment, one being for ascertaining the adherence to the use of oral antidiabetics and the other for adherence to the use of insulin, as well as to assess differences in adherence between these two modes of drug therapy.Method
a methodological study undertaken with 90 adults with Type 2 Diabetes Mellitus. The criterion-related validity was verified using the Receiver Operating Characteristic curves; and for the reliability, the researchers calculated the Cronbach alpha coefficient, the item-total correlation, and the Pearson correlation coefficient.Results
the oral antidiabetics and the other showed sensitivity of 0.84, specificity of 0.35 and a Cronbach correlation coefficient of 0.84. For the adherence to the use of insulin, the values found were, respectively, 0.60, 0.21 and 0.68. A statistically significant difference was found between the final scores of the two forms of the instrument, indicating greater adherence to the use of insulin than to oral antidiabetics.Conclusion
it is concluded that the two forms of the Measurement of Adherence to Treatment instrument are reliable and should be used to evaluate adherence to drug treatment among people with diabetes mellitus. 相似文献To assess the effectiveness of mandibular advancement devices (MADs) for the treatment of obstructive sleep apnea syndrome (OSAS) over a long-term follow-up in patients non-compliant with continuous positive airway pressure (CPAP) and to identify potential predictive factors of response to MADs.
Methods:
Fifteen OSAS patients were enrolled. Apnea-hypopnea index (AHI) and daytime sleepiness were assessed at baseline and at the end of follow-up. Potential baseline predictors of treatment effectiveness were assessed.
Results:
AHI and Epworth Sleepiness Scale (ESS) scores improved significantly with MADs. Sixty per cent of patients were ‘responders’, of whom 33% were ‘full responders’. Sixty-seven per cent of patients showed total compliance. No correlations between the potential predictors and the response to MAD therapy were found.
Discussion:
Effectiveness of MAD therapy was shown over a long-term follow-up in OSAS patients with low compliance to CPAP. Efforts to identify predictive success factors fell short. 相似文献
