Abstract

Introduction: The therapeutic adherence is a key aspect in the success of the oncology treatment, however its measurement is a challenge within the health system. Likewise, there are no valid or constructed scales to assess adherence in patients with breast cancer. Objective: To determine the psychometric properties of the Breast Cancer Therapeutic Adherence Scale (EAT-CaMa). Method: A non-experimental, instrumental design with a non-probabilistic sampling was used, for convenience. One hundred eighty nine participants with a diagnosis of breast cancer, between 21 and 84 years old, were included. Statistical analysis: An exploratory factor analysis was performed. Results: An exploratory factor analysis and internal consistency were carried out. Results: The EAT-CaMa of 27 questions obtained a global internal consistency α = 0.81 and an explained variance of 64%. Self-efficacy and physician-patient communication factors were identified, as well as several indicators. Conclusion: The EAT-CaMa is a short, valid and reliable instrument for the multidimensional evaluation of adherence to treatment in the Mexican breast cancer population. The identified factorial structure corroborates components reported in the literature and clinically relevant. It is recommended for use in clinical care (initiation and follow-up of treatment) and in future research.
