Avaliação das propriedades psicométricas dos instrumentos de autorrelato utilizados na determinação da adesão às terapias oncológicas orais não-hormonais: uma revisão sistemática

Abstract

Cancer is one of the main causes of death in Brazil and in the world. Adherence to oral therapies aimed at treating the disease is a serious problem experienced in several types of cancers. In order to be able to identify these factors related to non-adherence, several methods are used, among them, self-report scales, which are low-cost, easy to apply and capable of measuring and identifying the causes of therapeutic non-adherence, stand out. Objective: To evaluate the psychometric properties of self-report instruments used to determine adherence to oral antineoplastic therapies. Methodology: Systematic literature review by searching the PubMed and Scopus databases, including studies published until March of 2021. Results: Chronic myeloid leukemia and multiple myeloma were the most common types of cancer in the studies, ranging from 33 to 66 months to diagnosis. The adherence rate ranged between 57% and 97%. Regarding the use of measuring instruments, the Morisky scale was the most used, followed by the ASK-12, and only 1 study developed a scale to measure adherence in cancer patients. Conclusion: The small number of scales used to measure adherence to cancer treatment, generally adapted to deal with patients with this type of disease, is an indication for the development or validation of new scales in the face of the critical scenario of the disease.
