Validation of the Adherence Determinants Questionnaire scale among women with breast and cervical cancer

Abstract

Objectives: the aim was to translate and culturally adapt the Adherence Determinants Questionnaire scale for the Portuguese language in the Brazilian context, and to check its reliability and validity to analyze the elements of the adherence of patients to the clinical treatment for breast and cervical cancer. Method: this was a methodological study, carried out in two oncology reference centers. The sample consisted of 198 participants, with 152 being treated for breast cancer and 46 being treated for cervical cancer. The content validation was performed by a committee of experts. The construct validation was demonstrated through factor analysis and the reliability was analyzed using Cronbach's alpha. Results: the committee of experts made the necessary adjustments so that the scale was adapted to the Brazilian context. The factor analysis suggested a reduction from seven to five factors and the maintenance of 38 items similar to those of the original scale. The reliability, investigated through Cronbach's alpha, was .829, showing high internal consistency. Conclusion: it was concluded that the Brazilian version of the Adherence Determinants Questionnaire scale is a valid and reliable instrument that is able to measure the elements of adherence to the treatment for breast and cervical cancer.

Motivation and Continuance Intention towards Online Instruction among Teachers during the COVID-19 Pandemic: The Mediating Effect of Burnout and Technostress

“…After the Promax rotated factor, the first dimension of the scale, labeled TPK self-efficacy, explains 37.246% of the total variance (and the second dimension of the scale, labeled burnout and technostress, explains 16.589% of the total variance). The value of the Cronbach’s alpha coefficient corresponding to the entire scale found was 0.923, demonstrating that the applied survey has very good internal consistency [ 129 ]. The results of the EFA analyses showed that the value of KMO was 0.949, and Bartlett’s sphericity test was significant [ 130 ].…”

Development and validation of an instrument to assess Brazilian healthcare professional providers’ knowledge on sickle cell disease

“…Regarding reliability, the results show satisfactory indexes, especially when compared with instrument validation studies, thus guaranteeing reliability of the instrument, making it validated for later studies 22, 26. Cronbach's alpha presented a value of 0.818, indicating a high internal consistency.…”

“…A total of 102 professional healthcare providers agreed to participate, 52% (53) of them having taken the above-mentioned distance education course. This number is in accordance with the adopted methodological framework, which recommends a number of participants between 5 and 10 times the number of the items in the instrument, with no need for sample calculations 21, 22. The objective was to verify if the instrument was reliable to assess the knowledge on sickle cell disease acquired by professional healthcare providers.…”

Translation and adaptation of the Competencias Esenciales en Salud Pública para los recursos humanos en salud

“…The process of translation and cross-cultural adaptation requires a method for achieving equivalence between the source language and the target language. For instruments and documents used by cultures other than that of the source language, the ideal is not only the language translation, but a cultural adaptation to maintain the instrument content validity in different cultures 7 - 8 . This situation demands planning before starting the process 8 .…”
